The train driver in the courtyard

early morning.

Li Aiguo was still getting dressed in the inner room when He Yushui's voice came from outside.

"Brother, do you have any more wolf fangs at home? Can I borrow one?"

As Li Aiguo put on his clothes, he said, "What would a young lady like you need that thing for?"

"I was just curious, brother~" He Yushui said coquettishly from outside the curtain.

"Alright, there's only one left." Li Aiguo took out a wolf tooth with a red string strung on it from the drawer, walked out, and handed it to He Yushui.

"Thank you, brother." He Yushui took the wolf tooth, clutched it in her hand, and ran off in a flash.

By the time Chen Xueru brought her the cornmeal porridge, she had already disappeared.

"Why is Yushui interested in Wolf Fang out of the blue?"

Li Aiguo took the cornmeal porridge, slurped it up, then picked up a steamed bun and said while eating, "It's probably for a male classmate."

“She’s so young and already dating, this is really affecting her studies. I have to talk to her about this.” Chen Xueru really treated He Yushui like her own younger sister, and she was getting anxious.

Li Aiguo grabbed her arm: "It's okay. He Yushui is more mature than most girls and knows how to behave."

Recalling He Yushui's background, Chen Xueru said, "Yes, her mother passed away, her father ran away, and her older brother was imprisoned. It's certainly been a difficult life. Don't let her cheerful demeanor fool you; you can't imagine how much suffering she endures inside."

She sighed and said, "But it can't affect my studies. Never mind, I'll try to find out about it from the side when I have time."

Xiao Hongsheng was munching on a steamed bun, tilting his head as he said, "I'm not interested in dating. The girls in my class are such a pain; they're always crying."

"Keep eating."

Thinking about getting to the BAIC factory, Li Aiguo didn't delay. He teased Xiao Hongsheng, picked up the canvas bag he had prepared in advance, and walked out the door with a hearty laugh.

As soon as I arrived at the Intermediate People's Court, I saw Liang Ladi practicing cycling.

"Brother Aiguo, look at my new Flying Pigeon, what do you think?" Liang Ladi said, standing on one foot and looking at Li Aiguo as he approached.

Li Aiguo replied with a smile, "It's quite beautiful. Are you planning to install a grinding wheel?"

“Hey, if you hadn’t reminded me, I would have completely forgotten about this. Once we get to the factory, I’ll find an old one to install.” Liang Ladi’s eyes lit up.

After chatting for a bit, Li Aiguo hopped on his bicycle and leisurely rode to the BAIC factory.

In those days, the BAIC factory, having obtained truck blueprints, took on the important task of producing trucks, and the level of activity far exceeded the original timeline.

Early in the morning, the gate was crowded with vehicles, including trucks from out of town that came to purchase goods and those transporting spare parts; it was very lively.

As soon as Li Aiguo parked his bicycle at the factory gate, a middle-aged man in a gray Zhongshan suit walked over quickly.

"Patriotic comrade!"

"Chief Engineer Liu." Li Aiguo tied up his bicycle and warmly extended his hand to shake hands with Chief Engineer Liu.

When Chief Engineer Liu first introduced the Cherbel truck technology, he and Li Aiguo analyzed the blueprints together within the ministry.

After learning that BAIC Group refused to transfer personnel, Li Aiguo thought of this old friend.

"It's a mess here. Come on, let's talk in my office."

Upon entering the factory, Li Aiguo looked around and praised, "The BAIC factory is getting better and better. When I came here two years ago, it was still a wasteland, wasn't it?"

Chief Engineer Liu proudly straightened his back and explained with a smile, "It was all built last year. Due to the urgent need for trucks, the factory's size has doubled."

Chief Engineer Liu did not explain in detail where the trucks went.

Li Aiguo saw rows of dark green military vehicles driving out of the parking lot and understood that these vehicles were being sent to the front lines in the South Asian subcontinent.

Due to confidentiality principles, Li Aiguo didn't ask any more questions or look around, and followed Chief Engineer Liu into the office.

Chief Engineer Liu poured tea and handed it over, saying with a smile, "Comrade Aiguo, you're such a busy man, you must have something to discuss with me today?"

“I can’t hide it from you.” Li Aiguo took out the transfer order that had been rejected by the BAIC factory from his canvas bag and handed it over: “Old Liu, I need this person here. Do you think you can find a way?”

"Transferring people? That's easy."

Chief Engineer Liu took the transfer order, glanced at it, and when he saw Deputy Section Chief Niu's name, his expression changed slightly.

"It turns out it was rejected by the technical department."

"What?" Li Aiguo asked curiously.

"To put it simply, Deputy Section Chief Niu is Yu Shu's direct superior. Although his position isn't high, the transfer order can't bypass him. Even the personnel department would find it difficult to forcibly transfer someone," Chief Engineer Liu explained the procedure.

After hearing this, Li Aiguo had only one feeling: "It's easier to see the King of Hell than to deal with his underlings."

"How about this, I'll give Section Chief Niu a call, he should be willing to do me that favor."

Chief Engineer Liu didn't pay much attention at the time, after all, he was a senior engineer in the factory and had a certain status.

Even if a request is made to the factory manager, it will be approved as long as it does not violate principles, let alone the deputy head of the technical department.

What Chief Engineer Liu didn't expect was that Deputy Section Chief Niu, who was initially very enthusiastic, suddenly became cold after hearing the name Yu Shu.

"Chief Engineer Liu, it's not that I don't want to release him, but Yu Shu has a disciplinary record and was once responsible for a major production accident. If someone like that is transferred to another unit and causes any trouble, our BAIC plant will also suffer the consequences. Please understand."

"Yeah."

Chief Engineer Liu, being a veteran chief engineer, understood Deputy Section Chief Niu's intentions perfectly. He emphasized, "The person who came to transfer people this time is Comrade Li Aiguo from the Qianmen Locomotive Depot. The blueprints for our factory's truck production were obtained by him. Section Chief Niu, please reconsider."

"There's nothing to consider. As long as I'm in this deputy section chief position, I can't be transferred."

Snapped!
With a cold remark, Deputy Section Chief Niu hung up the phone.

He picked up the enamel mug and gulped down several mouthfuls before he recovered.

Officer Chen leaned closer and asked in a low voice, "Section Chief, what's wrong?"

"That Yu Shu from Workshop 5 is really dishonest; he actually tried to get someone to transfer him away."

Officer Chen was also aware of the entanglement between the two and whispered his advice: "Section Chief, Yu Shu has been in the workshop for a few years now. I think we should transfer him away so he won't be around you and will save you from getting annoyed."

Deputy Section Chief Niu grunted and said, "Xiao Chen, do you think I'm making things difficult for Yu Shu? No, I'm helping him. This kid is too stubborn. He needs to be tempered before he can be of great use. Otherwise, he'll definitely cause trouble."

If it weren't for the fact that Officer Chen knew about those past events, he would have actually believed his nonsense. But since this matter had nothing to do with him, he didn't try to persuade him further.

"Section Chief, I'm going to deliver the blueprints to the workshop."

After Officer Chen closed the door, Deputy Section Chief Niu's amiable expression vanished, replaced by a sinister grin.

"Yu Shu, Yu Shu, now you know how to get anxious?!"

"Back then, you suddenly pointed out that there was a problem with the blueprints, catching me completely off guard and almost getting me kicked out of my position as deputy section chief. Didn't you ever think this day would come?"

He muttered under his breath, a hint of malice flashing in his eyes: "If I don't sign, let's see who among you can transfer him away."

"Even if Deputy Section Chief Niu doesn't sign, as long as I raise it with the factory director and get him to give the order to the personnel department, you can take him away today." After hanging up the phone, Chief Engineer Liu sullenly thought of a solution.

Li Aiguo took a sip of tea and declined the offer.

"Let's go through the proper procedures."

Chief Engineer Liu was stunned: "Proper procedure?"

Without Deputy Section Chief Niu's signature, the person cannot be transferred. How can we follow the proper procedures?
Li Aiguo didn't answer him. Instead, he took out a cigarette from his pocket and handed it to him. After lighting one for himself, he asked, "I heard there was a man-made production accident here recently?"

"That's true. Yu Shu was punished for it."

"What is the specific situation?"

"Last year, when we started mass production of trucks, a batch of bearings produced in the workshop did not meet the standards. Later, the factory investigation revealed that Yu Shu was in charge of the parts drawings for the workshop. Due to Yu Shu's negligence, significant losses were caused, and he should have been severely punished."

Seeing that Chief Engineer Liu didn't continue, Li Aiguo asked, "What's wrong?"

"Speaking of which, Yu Shu was quite unlucky. At the time, Engineer Zhou, who was in charge of the blueprints, was hospitalized due to illness, and Yu Shu was sent to temporarily fill in, which resulted in this incident."

Chief Engineer Liu sighed with regret and said, "Taking this into account, the factory demoted him to a workshop and gave him a major demerit."

Oh, he was just a temporary worker!
This rhythm sounds so familiar!
Li Aiguo flicked his cigarette ash and said, "How come I heard this has nothing to do with Yu Shu?"

Chief Engineer Liu stood up, went to the cabinet, rummaged around for a while, and handed a document to Li Aiguo: "This is the original investigation report."

While Li Aiguo was reviewing the documents, Chief Engineer Liu continued, "After the accident, Yu Shu did point out that the production accident had nothing to do with him, but was due to a problem with the drawings provided by the technical department."

As a technician, he had previously reminded Deputy Section Chief Niu, but Deputy Section Chief Niu had not taken it seriously.

Didn't you conduct any investigation?

"The security department and the technical department conducted a joint investigation and ultimately proved that there was nothing wrong with the drawings. It was Yu Shu who misread the drawings and caused the production accident in an attempt to shirk responsibility."

Li Aiguo flipped through the documents, and the contents recorded therein were indeed as Chief Engineer Liu had said; all the evidence pointed to Yu Shu.

"Do you still have that original blueprint?"

"In the archives room of the technical department." Chief Engineer Liu realized what Li Aiguo was about to do, and his face immediately turned ugly: "Aiguo, I'm not trying to persuade you, but the investigation is over. If you want to restart the investigation, the factory leaders will definitely not agree."

This is true.

If the final investigation results are different from the previous ones, it would be a slap in the face to those leaders, and no one would want to invite trouble.

Li Aiguo is a colleague from another factory. How can he persuade those factory leaders?
Faced with Chief Engineer Liu's question, Li Aiguo simply smiled faintly: "I remember that the production of trucks involves classified information, right? Didn't you report this accident to the security department at the time?"

"After the factory's security department got involved, they found that Dieter was not involved, so they decided to keep the matter quiet and avoid trouble." Chief Engineer Liu still didn't understand what Li Aiguo was up to.

Li Aiguo's expression gradually turned serious: "All work must be carried out according to proper procedures. This is for the protection of those in charge above, and also for your own safety. Your security personnel have not handled things properly."

"Yes, yes, yes." For some reason, Chief Engineer Liu always felt a little uneasy when facing Li Aiguo now.

Li Aiguo stood up and looked at Chief Engineer Liu: "Old Liu, can I borrow your phone?"

"Come here." Chief Engineer Liu still didn't understand what Li Aiguo wanted to do, but he picked up the phone and handed it over.

Li Aiguo took the phone but did not immediately make a call. Instead, he looked at Chief Engineer Liu.

Despite his many doubts, Chief Engineer Liu still left the office.

He stood at the doorway, lit a cigarette, and squinted slightly: "What exactly does this Li Aiguo want?"

After a while.

The office door opened, and Li Aiguo came out and said, "Let's go to the security department and find a way to investigate this matter thoroughly."

Chief Engineer Liu was completely bewildered. How could Li Aiguo expect the security department to cooperate? But out of politeness, he followed behind.

Before the two even reached the entrance of the security department, Chief Qin of the security department of BAIC Factory hurriedly pushed open the office door and came face to face with them.

Section Chief Qin looked Li Aiguo up and down, his eyes lighting up: "You must be Comrade Li Aiguo from the Qianmen Locomotive Depot."

"Hello, Section Chief Qin, I'm afraid I'll have to trouble you this time." Li Aiguo extended his hand.

Section Chief Qin grabbed his hand and said, "Comrade Aiguo, I just received a notice from above, asking me to cooperate with you in investigating a previous case. Please give the order." Seeing this, Chief Engineer Liu, recalling the phone call he had just received, couldn't help but gasp.

It's important to know that BAIC is now a key automobile factory in China, and Section Chief Qin is a very high-ranking official. Li Aiguo only made one phone call, yet Section Chief Qin cooperated so readily. Who exactly did he make that call to?

In particular, the fact that Section Chief Qin, a very composed person, now seemed somewhat panicked made Chief Engineer Liu even more uneasy.

Li Aiguo was unaware of Chief Engineer Liu's thoughts, and even if he had, he wouldn't have cared.

"Section Chief Qin, you are a few years older than me, so I will call you Old Qin."

“good good”

Section Chief Qin remembered the origin of the phone call and was worried that the young man in front of him might take the opportunity to cause trouble.

Seeing Li Aiguo's softened attitude, the heart that had been hanging in my throat instantly settled down.

He ushered Li Aiguo into his office and asked, "Aiguo, do you think there's a problem with the case of the workshop production accident a year ago?"

“Although I haven’t been in charge of production in the workshop, I have worked there. It’s impossible for a junior technician to draw such important parts drawings, right? Besides, Yu Shu was only temporarily transferred to be in charge of bearing parts drawings!”

Upon hearing this, Section Chief Qin's expression immediately changed.

Drawings in mechanical factories are divided into engineering drawings, assembly drawings, part drawings, structural drawings, flowcharts, process drawings, and final assembly drawings.

The part drawings provide detailed descriptions and displays of the structure and dimensions of individual parts, including the specific shape, size, tolerances, and processing methods of the parts, which directly affect whether the accessories are qualified.

This is considered one of the most important types of drawings.

Generally, these drawings need to go through three rounds of review before they are finally sent to the workshop.

“This matter is being investigated by Deputy Section Chief Niu. I’ll call him over.”

After realizing there was a problem, Section Chief Qin immediately notified Deputy Section Chief Niu of the Technical Section.

This was the first time Li Aiguo had ever met the legendary Deputy Section Chief Niu.

A middle-aged man, short and stocky with a large belly, entered the office with his beady eyes that darted around.

"Niu Ke, what happened in the production accident in Workshop 5 a year ago? Could Yu Shu have made the decisions on the parts drawings all by herself?"

Deputy Section Chief Niu sensed something was wrong when he received the notification, and upon hearing these words, a hint of panic flashed in his eyes.

“I’ve checked. But the technicians in the technical department all denied Yu Shu’s statement. Also, the three signatures on the drawings are all Yu Shu’s, which is enough to prove that he is directly responsible for the accident.”

"Nonsense, utter nonsense! How can the technical department let one technician be in charge of three procedures!" Section Chief Qin was so angry that his face was red, but as the leader of the security department, which was a different system from production, he couldn't do anything about it.

Actually, this kind of thing is not uncommon. These days, due to the lack of rules and regulations and the shortage of personnel, many technical personnel hold multiple positions.

It's really outrageous that something like this happened at the BAIC factory.

Deputy Section Chief Niu quickly said, "Sir, after the accident, I have already apologized to the factory. We are now implementing a three-tier management procedure, so there will definitely be no problems."

Li Aiguo interjected, "So, you personally identified Yu Shu as the person directly responsible for the accident?"

Deputy Section Chief Niu had noticed Li Aiguo long ago, but since no one introduced him and he hadn't dared to ask, he hesitated before asking, "And you are?"

"This is Comrade Aiguo from the Qianmen Locomotive Depot," Section Chief Qin wanted to introduce Li Aiguo, but didn't know how, so he could only say, "Just answer Comrade Aiguo's questions honestly."

Deputy Section Chief Niu then realized that this guy was the one behind it all.

"Ahem, Comrade Aiguo, don't believe Yu Shu's one-sided story. This guy is all talk and no action, and he's full of bad intentions."

Upon hearing this, Section Chief Qin sighed inwardly. In fact, Li Aiguo's repeated questioning earlier was already giving Deputy Section Chief Niu a chance.

If he is willing to tell the truth, there may still be a chance to salvage the situation.

Unfortunately, it's too late now.

As expected, seeing that Deputy Section Chief Niu was still insisting on Yu Shu, Li Aiguo stood up and said, "Alright, now take me to the technical department. I want to personally examine that drawing."

Deputy Section Chief Niu's expression changed slightly: "On what grounds do you investigate our technical section?"

Section Chief Qin stood up and said coldly, "Deputy Section Chief Niu, please cooperate with Comrade Aiguo's work."

Deputy Section Chief Niu's heart skipped a beat, but he didn't pay much attention to it.

After all, he learned his methods from an old man; otherwise, the security department wouldn't have been unable to find anything.

"If you are upright, you are not afraid of slanted shadows."

"Since the leader has given the order, I will naturally obey."

Deputy Section Chief Niu made a sarcastic remark and led Li Aiguo, Section Chief Qin, Chief Engineer Liu, and several others into the Technical Section.

It was during working hours, and the technicians in the technical department were quite surprised to see so many people arrive.

"Section Chief, who are these comrades?"

“You continue with your work. The comrades above think that our technical department framed Yu Shu and are investigating the situation. This has nothing to do with you.”

This statement, seemingly an explanation, was actually a warning to the technicians not to meddle in other people's business.

The technicians all understood the implied meaning, exchanged glances, and lowered their heads.

Although they wanted to help Yu Shu, what could they do when Deputy Section Chief Niu had gathered evidence?

Li Aiguo knew what Deputy Section Chief Niu was thinking, but he didn't care.

"Deputy Section Chief Niu, where is that blueprint?"

"Don't rush," Deputy Section Chief Niu said, his tone becoming unfriendly.

Deputy Section Chief Niu couldn't understand why Li Aiguo could be treated so cautiously by Section Chief Qin. As the deputy section chief of the technical department, as long as he wasn't caught doing anything wrong, even if the King of Heaven himself came, he couldn't do anything to him.

Deputy Section Chief Niu opened the office door, took a set of blueprints from the safe, and threw them on the table.

"See for yourself."

Li Aiguo was not angry; instead, he picked up the blueprints with a smile.

The blueprints were indeed as Section Chief Qin described, with only Yu Shu's signature, and there seemed to be no problem with them.

"So, do you believe me now?"

Deputy Section Chief Niu, his beer belly protruding, swept his sinister gaze across the crowd: "Let me tell you the truth, Yu Shu was only treated leniently back then because I pleaded with the factory leaders. And this kid, he repays kindness with enmity! I'll definitely get him later..."

The words stopped abruptly.

When Deputy Section Chief Niu saw Li Aiguo take the blueprints to the window and hold them up to the sun, his expression changed slightly.

"You think I tampered with the blueprints? That's an insult to me."

Deputy Section Chief Niu's face turned red, and his lips twitched twice, perfectly conveying his anger.

If this happened in later generations, he would definitely win an award for best villain.

Section Chief Qin leaned closer and examined the blueprints for a while: "Aiguo, these blueprints look fine, don't they?"

Li Aiguo handed over the blueprints and said with a smile, "Old Qin, have you ever heard of a forgery method in the antique trade called 'turning the mountain'?"

"Turn the mountain?"

"Changing the mountain top, also known as moving the mountain top, is one of the methods of altering the version of the document to commit forgery."

The main method is to use the signature area as an interface, roll it thin into a slope, then flatten the carved part, brush paste along the edges, remove the carved part, glue the new signature on the paste-coated part, and let it dry on a drying rack.

Then, the traces were completely covered with a brush of the same color at the patched area, moistened with water, and then pasted smoothly onto the wall. This technique is so ingenious that it can be mistaken for the real thing.

Li Aiguo pointed to the signature and said, "The only drawback is that it is afraid of strong light. Even if it is a full-color brushstroke, as long as the back paper is held up to the light, the flaw will be visible."

Upon hearing this, Section Chief Qin quickly held up the blueprint. After clearly seeing the three signatures, his expression changed slightly: "As expected, there's a lingering fear."

He turned to Deputy Section Chief Niu and demanded, "How do you explain this?!"

Deputy Section Chief Niu never expected that the signature he had painstakingly created would be exposed.

"This, this wasn't me, it wasn't me."

Li Aiguo asked with a slanted eye, "You were in charge of keeping the blueprints, and you cooperated with the investigation. Besides you, who else had the opportunity to access the blueprints?"

Deputy Section Chief Niu was speechless for a moment, looking at Li Aiguo without daring to speak.

Li Aiguo turned to look at Section Chief Qin: "Will you be the one to conduct the interrogation, or will I?"

Section Chief Qin glanced at Deputy Section Chief Niu, then said to the few technicians who had gathered to watch, "Get out."

Those who followed him in quickly turned around and left upon hearing Section Chief Qin's words.

This is a huge deal. It could cause a major upheaval in the technical department, or even the BAIC plant. They dare not provoke that young man.

Li Aiguo unbuttoned his collar, pulled a pistol from his waist, and slammed it on the table.

"I don't want to waste any more words with you. You know what crime it is to deliberately send problematic blueprints to the workshop in an attempt to disrupt production and affect major events on the frontier."

Deputy Section Chief Niu was terrified and said through a wide grin, "This...this is all a misunderstanding, how could I dare?"

Before he could finish speaking, Li Aiguo raised his gun, released the safety, pointed it at him, and said, "If you dare to cheat on me again, I'll put a hole in you. You're going to get shot anyway, so a few days earlier won't matter."

Deputy Section Chief Niu never expected that Li Aiguo would use the same methods he used against Yu Shu to link the production accident with major events on the frontier.

A chill ran down his spine, and he knelt on the ground with a thud, saying, "I really didn't mean to! I was drunk that day and I really didn't know that the blueprint was faulty and would cause such serious consequences. Waaah... really, I really didn't know!"

Li Aiguo asked coldly, "So, it was indeed Yu Shu who found the problem with the blueprints, and you're ignoring it?"

Deputy Section Chief Niu cried and said, "Production is about to begin. If the blueprints are changed, I, as the section chief in charge, will be criticized. I thought it was just a small mistake, nothing serious, so I sent Yu Shu away."

As soon as these words came out.

Chief Engineer Liu couldn't hold back any longer and grabbed Deputy Section Chief Niu by the collar, shouting, "As the leader of the technical department, don't you know that the dimensions of the parts cannot be wrong at all?"

Your subordinates pointed out your problems, but instead of accepting them, you dismissed them.

After the accident happened, you then arranged for someone else to take the blame.

"Deputy Section Chief Niu, do you have any sense of morality whatsoever?"

"It's my fault, I'm a sinner in the factory, but I really didn't do it on purpose, and I'm not Dieter." Deputy Section Chief Niu was already sobbing uncontrollably.

The cicadas outside the window were chirping shrilly. Deputy Section Chief Niu lay sprawled on the ground, convulsing, like a stranded fish.

Section Chief Qin looked at Deputy Section Chief Niu, who had been so arrogant just half an hour ago, and felt a pang of regret.

The train driver from the Qianmen Locomotive Depot arrived here and solved a long-standing case in less than ten minutes.

It seems he does have connections with those people at the weather station.
