The train driver in the courtyard

"Name?"

"Don't you know?"

Inside the interrogation room of the Qianmen Locomotive Depot Police Station.

Minister Niu of the Armed Forces Department and Zhou Ke were interrogating Yi Zhonghai. Li Aiguo, who knew Yi Zhonghai, was also sitting next to them.

Zhou Ke slammed his hand on the table: "Don't you already know?"

Yi Zhonghai shuddered in fright and quickly answered honestly, "Yi Zhonghai."

"Origin?"

"Labour farms".

"Position?"

"Seventh-level fitter at the steel rolling mill."

After the routine questioning ended, Zhou Ke looked up at Li Aiguo, signaling him to continue the questioning.

Li Aiguo didn't rush to speak. He first took out a cigarette case from his pocket, lit one, took two deep drags, and then said in a deep voice, "Why did you steal military secrets?"

Yi Zhonghai was already on tenterhooks the whole way, and the oppressive atmosphere in the interrogation room made it even harder for him to breathe.

Upon hearing this, his legs went weak and he almost slipped off his chair. He hurriedly protested, "I didn't steal military secrets! I'm innocent!"

Li Aiguo continued, "Why did you want to steal military secrets?"

Yi Zhonghai: "."

He felt as if his whole body had grown mouths and he could explain everything.

"I was really just fishing. I had no idea you guys were conducting experiments there. Even if you gave me a hundred lives, I wouldn't dare venture into the restricted area!"

Yi Zhonghai actually cried at this moment, and he really cried.

If this charge is proven true, his life is over, and he'll never be able to leave this police station.

Li Aiguo pressed him for more questions, but Yi Zhonghai kept repeating the same explanation.

In a moment of confusion, he mistakenly entered a restricted area while trying to catch fish for a deaf elderly woman to use for her medicine.

Unable to get any information from him, Zhou Ke ordered Yi Zhonghai to be taken away and Yan Bugui to be brought up.

The old man looked at the cold steel chair and subconsciously took two steps back: "Can I not sit here? Something just doesn't feel right."

Li Aiguo slammed his hand on the table, his tone stern: "No! You're now a suspect in a case, don't you know your own identity?"

Yan Bugui shrank back in fright, not daring to say another word. He obediently moved to a chair and sat down. As soon as he was settled, he hurriedly distanced himself from the situation.

"This has nothing to do with me! I took Yi Zhonghai fishing, but I really didn't know he would dare to go into a restricted area!"

Yan Bugui was also wronged.

This time, while fishing, not only did he break his bicycle, but he was also arrested.

Li Aiguo asked the same question as usual, and Yan Bugui's answer was very similar to Yi Zhonghai's, both saying that they had mistakenly entered a forbidden area.

At this moment, the cadre who went to the courtyard to conduct the investigation returned.

The survey results were similar to those of Yi Zhonghai and Yan Bugui; many residents reported that the deaf elderly woman was ill and needed fish as a medicinal ingredient.

Zhou Ke rubbed his temples, both amused and exasperated: "After all this fuss, it really was just for a fish?"

Minister Niu couldn't help but laugh: "These two old guys are really bold, daring to trespass into military restricted areas."

Even if the two were not Dieter, they violated the rules by knowingly entering a military restricted area.

Some people do this all the time: they go to the airport to take pictures, and when you investigate further, it turns out they're actually doing favors for outsiders.

After thinking for a moment, Zhou Ke suggested, "Let's notify the local street office to come and pick them up, and let them teach them a lesson."

Minister Niu nodded in agreement: "Let's do it that way."

Subsequently, Minister Niu personally called Director Wang of the Subdistrict Office.

Director Wang on the other end of the phone was completely stunned after hearing this.

Yi Zhonghai and Yan Bugui, the two stewards of the courtyard house, were arrested together.

When she arrived at the Qianmen Locomotive Depot Police Station, she met Yi Zhonghai and Yan Bugui in the detention room.

Yan Bugui was squatting in the corner, not daring to utter a sound.

As soon as Yi Zhonghai saw Director Wang, he burst into tears: "Director, I was bombed."

"Huh? Who?!" Director Wang exclaimed in surprise. Yi Zhonghai pointed to Li Aiguo behind Director Wang, gritting his teeth as he said, "It's him, Li Aiguo!"

Director Wang: "."

After figuring out the whole story, Director Wang of the neighborhood office was also completely baffled.

The neighborhood committee repeatedly emphasized confidentiality at its meetings, but these two old men in charge actually went to peek at the small plane.

Director Wang took the two back to the subdistrict office and immediately enrolled them in a training class.

Yi Zhonghai looked at Director Wang and said somewhat awkwardly, "Director, can I go back for a bit now?"

"What's wrong?"

"My pants."

Director Wang then noticed a pungent, strange smell; he hadn't thought much of it before because he was so focused on handling the matter.

He quickly took two steps back, a look of disdain on his face: "Old Yi, you're so old, how can you still..."

Yi Zhonghai explained with a mournful face, "Director, you have no idea how outrageous Li Aiguo was! He flew his plane and dropped bombs on me. I was so scared my legs went weak and I couldn't control myself at all..."

"Alright, alright, go back now. And Yan Bugui, you go back too, come back for training tonight." Director Wang said helplessly, waving his hand at the two of them.

The two felt as if they had been granted a pardon and returned to the courtyard house looking dejected.

As soon as we entered the courtyard, Xu Damao approached us with a grin.

The voices were neither too loud nor too soft, just loud enough for the surrounding residents to hear: "Hey, isn't this our compound's 'Big Diet' Yi Zhonghai and Yan Bugui?"
"You're finally back! You two are really something, daring to even trespass into a military restricted area!"

Yi Zhonghai's face darkened, and he asked, "Da Mao, how did you know about this?"

Xu Damao smiled sinisterly: "You don't know yet, do you? The locomotive depot has already reported your situation to the steel rolling mill! You'll be going to work tomorrow... Hehe, you'll see what happens then."

Yi Zhonghai's face turned deathly pale instantly, and his heart skipped a beat.

"I knew Li Aiguo wouldn't let me off so easily. Turns out he was waiting for me here!"

Li Aiguo wasn't really concerned about Yi Zhonghai's situation, because he had just received a notification from Section Chief Xing.

Tomorrow, aviation experts will visit the Qianmen Maintenance Depot's workshop to see small aircraft.

It is said that a high-ranking leader will also be coming.

Right now, Li Aiguo's most important task is to rush out the flight helmet.

This morning, Lanzhou Chemical Company delivered the first batch of aramid fibers to the laboratory by train.

This is a small-batch sample produced in the laboratory, weighing only a few dozen kilograms, but it's enough to manufacture a batch of flight helmets.

The flight helmet developed by Li Aiguo has an outer shell made of aramid fiber and special engineering plastic, which has high structural strength and light weight.

The inner lining uses a layered cushioning structure, with the inner layer consisting of sponge and knitted mesh fabric.

The helmets can be made in a motorcycle helmet workshop; the foam is readily available, and the most crucial part is the mesh fabric.

This thing was originally designed to replace rigid polyetheretherketone (PEEK) cushioning boards.

There are strict requirements for the thickness and the density of the stitches; it is best to find an experienced tailor to do it.

“Aiguo, didn’t your sister-in-law used to be a tailor?” Zong Xianfeng came back from the helmet workshop after unloading the materials and saw Li Aiguo staring blankly at the specially made cloth. He reminded him.

Li Aiguo suddenly slapped his forehead: "How could I have forgotten about this?"

In recent years, Ms. Chen has taken over the household's clothing production, and her sewing skills have become comparable to those of a master seamstress.

At dusk, the fiery clouds on the horizon were a beautiful sight.

When Li Aiguo returned to the courtyard house on his mountain bike.

The residents of the compound had already spread the word about the arrests of Yi Zhonghai and Yan Bugui.

When they saw Li Aiguo return, the residents greeted him warmly.

"Aiguo, I heard you flew a plane. Did you fly it really high?"

"Was Yi Zhonghai, that Dieter, hiding in the bushes when you spotted him?"

"Yi Zhonghai even wet his pants, hahaha!"

"Uncle Patriot, can you tell us about the time you flew a plane and bombed Dieter?"
