The train driver in the courtyard

Monday morning.

Li Aiguo first rode his motorcycle to the Changxindian Motorcycle Factory.

Tanker trains have begun mass production.

The first batch of two vehicles will be shipped out at the end of the month and delivered to the State Farm.

Chen Xingyi is now also a team leader in the technical department, specifically responsible for technical issues in production.

After a brief chat with Chen Xingyi, Li Aiguo rode his motorcycle back to the Qianmen Locomotive Depot.

Section Chief Xu and Chief Engineer Wang from the State Farm General Farm have arrived at the Qianmen Locomotive Depot, accompanied by two railcars of supplies.

With pork, beef, and refined white flour, it must be said that life at the State Farm General Farm was indeed prosperous.

Section Chief Xing was overjoyed and led his men to unload the supplies. He then instructed Li Aiguo to take good care of the comrades from the State Farm.

Li Aiguo was not concerned about the supplies, but rather about the Agricultural Reclamation General Farm's opinion on the development of a new type of oil pumping machine.

The two seemed somewhat embarrassed upon hearing Li Aiguo's question.

"That's the situation, Comrade Aiguo. The leaders don't agree on the oil pumping unit." Section Chief Xu still wanted to keep it a secret, but Engineer Chen didn't care about the details and told him everything.

Li Aiguo was not surprised.

Trust always has inertia.

In this era, although Big Brother no longer wants to be the Big Brother, his image still remains in the hearts of many.

Especially in the early stages of the construction of Daqing Oilfield, our elder brother provided a lot of support and helped us solve our urgent problems.

Regardless of whether it was obtained through money and food, we cannot deny this fact.

"That's something for the leaders to worry about. We just need to work hard and build the double-headed oil pumping unit." Li Aiguo didn't care about these things.

If something is good, it will always have a chance to shine.

Section Chief Xu was initially worried that Li Aiguo would harbor resentment because of this. After all, the Qianmen Locomotive Depot's workshop had other jobs, so why would they insist on building oil pumping units for him?

Seeing Li Aiguo's attitude now, I feel like I underestimated this train driver.

"Comrade Aiguo, don't worry, even if we have to leave these two hundred-plus pounds of meat here, we'll still help you build the oil pump."

"Section Chief Xu, you're exaggerating. If you lose weight, the leaders there will definitely cause trouble for us when we return to the State Farms."

"Hahaha"

The atmosphere immediately eased.

Then Li Aiguo took out the blueprints he had prepared beforehand.

Although Section Chief Xu had studied the four-bar linkage structure proposed by Li Aiguo in advance, he still couldn't help but gasp when he saw the design on the drawings.

If an oil pumping unit is manufactured according to this design, its efficiency can be increased by at least 100%, and energy savings of 50% can be achieved.

But is this design feasible?

Section Chief Xu's fingers trembled slightly as he held the blueprints. He called out, "Old Chen, give me the draft paper."

Section Chief Xu took the pen and scrap paper, sat down, and began to calculate.

It took him two hours to complete all the calculations.

"Comrade Patriot, I never expected you to be an oil expert!" Section Chief Xu could no longer hide the shock on his face.

Oil pumping units are not just industrial machines; they must also be designed and manufactured according to local geological conditions, the depth of oil burial, the viscosity of oil, and other details.

The double-headed donkey-shaped oil pumping unit that Li Aiguo developed perfectly met the needs of the Daqing Oilfield, which explains why he was so amazed.

"I just enjoy reading. Didn't you guys give me some technical materials last time? I've studied them," Li Aiguo said with a smile.

Just from looking at some technical data, Section Chief Xu almost spat out a mouthful of blood when he learned that such a qualified oil pump could be built.

You should know that they have spent several years trying to replicate the Russian oil pumping unit, but they still haven't succeeded.

Engineer Chen's words reminded Section Chief Xu: "A national model worker like Aiguo, how could he not have some skills?"

"That's true." Section Chief Xu knew the value of this title and nodded.

The drawings were then checked twice more and modified in two places before the oil pumping unit entered the manufacturing stage.

Since the connecting rod is a vulnerable part and requires specially made steel, Section Chief Xu contacted Ansteel on behalf of the State Farm.

The motor was completed by a team led by Zong Xianfeng.

The most crucial component, the walking beam balancing system, was not manufactured by the Qianmen Locomotive Depot's workshop or maintenance workshop, so Li Aiguo contacted the coal machinery factory.

The coal machinery factory was particularly excited when it heard that a new type of oil pumping machine was to be developed.

"Comrade Patriot, we are manufacturers of mining machinery, and oil mines are also mines, so this is a perfect match for our expertise," the leader of the coal machinery factory said excitedly.

After hanging up the phone, Li Aiguo was somewhat dazed.

In later years, the coal machinery factory not only manufactured coal mining machines, but also became the largest oil pumping unit manufacturer in the country.

Could it be because I handed the order over to the coal machinery factory?

Did I change history, or did I unknowingly conform to its development?

Li Aiguo was also confused for a moment.

"Why think about these things? Just roll up your sleeves and get to work!" After a moment of distraction, Li Aiguo shook his head and perked up.

Instead of worrying about useless things here, we should hurry up and build the oil pump.

History is written by countless people walking on foot, not by standing still and imagining.

Manufacturing oil pumping units may seem complicated, but the Qianmen Locomotive Depot workshop has now established a dense network of relationships. If they can't manufacture something themselves, they can ask other manufacturers for help.

Wild car experts have given this network a name: the parts production network.

Li Aiguo felt it was particularly apt.

In the future, we should also establish a material supply network and a scientific research network.

Centered on the Qianmen Locomotive Depot workshop, we utilized manpower, resources, and technology from all over the country to bring back the good things for future generations.

Of course, one must walk one step at a time, and eat one bite at a time.

After the twin-headed furnace resumed production, Li Aiguo's life returned to normal.

Every day, I oversee the production of parts in the workshop. When I have time, I go to the 116 Project workshop to build helicopters with Professor Qi. After work, I can enjoy the life of my wife, children, and a warm bed.

They're living a wonderful life.

On Tuesday afternoon, Li Aiguo got off work a little earlier than usual. He rode his motorcycle to an alley in the east of Beijing and knocked on the door of a house at the end of the alley, according to the address on the note.

The one who opened the door was Zuo Dongfang.

"Aiguo, what brings you here?"

"I have news about the old wild boar you asked me to find last time, so I thought I'd drop by to see you, my old brother." Li Aiguo said, waving the net in his hand.

Seeing the fruit, snacks, and a bottle of Moutai liquor in the net bag, Zuo Dongfang felt a little embarrassed: "Since you're already here, why bring gifts?"

"What, are you just going to make me stand outside?" Li Aiguo knew Zuo Dongfang's temperament, so he deliberately put on a stern face.

"Oh, come in quickly. Our family isn't well-off, please don't mind."

Zuo Dongfang quickly ushered Li Aiguo into the house. The house was cramped, consisting of only a dozen or so single-story rooms. There was a bed on the east side and a coal stove and pots and pans near the door on the west side.

The house was small, but it was very clean.

Li Aiguo sat down, handed the slip of paper with the address written on it to Zuo Dongfang, and asked, "Brother, what do you think of my suggestion from last year?"

Li Aiguo felt that Zuo Dongfang had excellent martial arts skills and was also a successor of the sword technique. It was a pity that he was staying here. He wanted Zuo Dongfang to go to the armed forces department of the Qianmen Locomotive Depot to teach the young men martial arts.

Zuo Dongfang, however, was used to being carefree and preferred to do temporary work rather than go.

"Sigh, I'm fine as long as I'm full. My master told me when he passed away not to help the government." Zuo Dongfang knew that Li Aiguo meant well, but still waved his hand and refused.

Li Aiguo didn't force him, but just reminded him that adult wild boars are very strong and to be careful.

"Don't worry, my broadsword is no joke." Zuo Dongfang pointed to the broadsword hanging on the wall.

After chatting for a few minutes, Li Aiguo rode his motorcycle back to the courtyard house.

Tomorrow is the day Liu Guangqi goes to the Third Front factory. To send Liu Guangqi off, Liu Haizhong has prepared a banquet at home and invited all the people in the compound with whom he has a good relationship.

The next morning, Liu Guangqi carried the luggage that his second aunt had prepared for him and left the courtyard house, looking back every few steps.

Liu Haizhong waved to Liu Guangqi as he watched his retreating figure.

"Hopefully this guy will behave himself."

“Dad, I’m the most honest one.” Liu Guangfu quickly raised his hand.

Liu Haizhong ruffled his hair.

"Good boy, I'll only give you two lashes today."

Liu Guangfu: "."

After Liu Guangqi left, the courtyard returned to its usual tranquility.

A week later, Section Chief Xu went to the Changxindian Locomotive Factory, escorted the first two oil tanker trains, and returned to the State Farm.

With one less key member in the studio, Li Aiguo was busier than ever. He made four or five phone calls that morning alone, all from factories that produced the parts.

Fortunately, the production of the parts is going smoothly so far, and assembly will be possible soon.

Just as Li Aiguo was about to continue working after hanging up the phone, it rang again.

"Hello, what? Chenjiayu Health Clinic? Zuo Dongfang is injured?"

Li Aiguo's heart skipped a beat. He asked the wild car expert to help him ask for leave, and hurriedly pushed open the door and went out.

I had only walked a few steps when I saw Zhou Ke driving in his big SUV.

"Patriotism, what's up?"

"If you don't have a job, come with me to the Qingshan Town Health Center."

"it is good."

Lately, Zhou Ke has been spending his days catching thieves on the railway and has worked on several cases with the weather station. Now he finds the job too boring.

Seeing that Li Aiguo was in trouble, he didn't hesitate and drove his big SUV towards Chenjiayu.

Chenjiayu is a small town dozens of miles away from Beijing, next to a mountain, which is where the old wild boar was discovered.

Chenjiayu Health Clinic is very small, with only two wards in the courtyard, so it was easy to find Zuo Dongfang.

He is currently sitting on the hospital bed with his abdomen wrapped in gauze, receiving an IV drip.

Upon seeing Li Aiguo enter, Zuo Dongfang struggled to sit up, but winced in pain.

"Brother Zuo, lie down comfortably." Li Aiguo walked to the bedside.

Zuo Dongfang said with a wry smile, "Brother Aiguo, I've really messed up this time. I'm sorry to have troubled you to make this trip."

"What? Even you are no match for a wild boar?" Li Aiguo asked in surprise.

Although wild boars are formidable, Zuo Dongfang is highly skilled in martial arts and has made thorough preparations, so dealing with them shouldn't be a problem.

"This time it's also my fault for being careless."

Zuo Dongfang recounted the situation, and Li Aiguo listened with great amazement.

Zuo Dongfang wasn't entirely careless. In order to hunt that old wild boar, he prepared an old hunting rifle in advance and also carried a large knife.

Zuo Dongfang tracked them on the nearby mountain for two days and did indeed find the old wild boar, but not just one, but more than a dozen.

"More than a dozen?" Zhou Ke was also taken aback. Wild boars did indeed travel in groups, but they were usually two large wild boars leading a group of piglets, which was like a family. It was rare to see more than a dozen adult wild boars together.

"There were at least seventeen or eighteen of them, all of them were plump and strong, weighing four or five hundred pounds each." Zuo Dongfang said with a wry smile, "I originally dug a trap to lure one over, but who knew that this group of animals would move in packs. Luckily, I dodged quickly and didn't get hurt."

"."

"Not injured? Then where did you get this injury?" Zhou Ke asked, puzzled.

"Cough cough." Zuo Dongfang coughed twice, aggravating his wound. His mouth twitched in pain, and he squeezed out a distorted sound: "Black Tiger!"

Li Aiguo's expression turned serious.

Is there really a black tiger in Chenjiayu?
"Are you sure it's a black tiger?" Zhou Ke had also heard of the legend of black tigers around the capital, but he thought it was just a rumor.

"That's right, it is indeed a black tiger. Both ears are black, and its fur is light black with dark black stripes. There's no mistake." Zuo Dongfang's pain had eased a bit by now, and he explained the situation in detail.

Zuo Dongfang was chased up the mountain by the wild boar and was thinking of setting a trap when the opportunity arose.

As soon as I looked up, I saw a black tiger leap out of the bushes.

Zuo Dongfang was a trained fighter and reacted quickly. He tried to dodge, but the tiger still managed to strike him in the abdomen. He rolled on the spot and tumbled down the hillside to escape the tiger.

After being injured, he staggered down the mountain and was found by passing villagers who took him to the hospital.

However, Zuo Dongfang was not a local, had no letter of introduction, and had suffered external injuries.

Although the hospital doctor bandaged his wound, he was told to contact his family to handle the paperwork and pay the fees.

“I don’t have any family left, so I thought of you, my brother.” Zuo Dongfang said, taking out a wad of money from his pocket and handing it over: “Here’s the money. I need to trouble you to be my guarantor this time.”

"What's money to me? I have it here." Li Aiguo had a good impression of Zuo Dongfang, a veteran martial arts master, and was determined to help him now.

He turned around to pay the fee.

A nurse walked over and said to Zhou Ke, who had just taken out a cigarette, "Comrade, you can't smoke in the hospital."

"I didn't smoke," Zhou Ke said, frustrated.

"Who knows if you've smoked or not? Put it away quickly, or the boss will yell at you again."

Zhou Ke wanted to argue with the nurse, but Zuo Dongfang smiled and said, "This is Nurse Zhou. She's the one who helped persuade the hospital leaders to bandage me first."

Zhou Ke looked the nurse up and down: "I didn't expect you to be such a nice person, even though you look so fierce."

Nurse Xiao Zhou was a little angry.

"Zhou Ke." Li Aiguo called out to Zhou Ke, and smiled at Nurse Zhou: "Nurse, I'm sorry, my friend here is just a bit short-tempered. Where is the cashier? We'll pay the bill."

"You're a nice person, unlike that comrade who was like a firecracker." Nurse Zhou had a good impression of Li Aiguo; he was tall and strong, and spoke gently, unlike the man next to him who was sobbing and making a fuss.

Zhou Ke rolled his eyes in anger; they were brothers who had been cared for by their mother.

Li Aiguo followed Nurse Zhou to the payment counter, wrote a letter of introduction on the windowsill, and handed it in.

"Comrade, even if you're going to forge something, you should at least do it away from me, right?" The toll collector was both amused and exasperated.

Actually, if someone forges a referral letter to get medical treatment, most people would turn a blind eye, but you can't do it openly.

“Patriotism means you can write a letter of introduction for your superiors, so why can’t they write one?” Zhou Ke walked over.

"Such a young leader?" The toll collector looked Li Aiguo up and down, then asked seriously, "What organization are you from? Do you have a phone?"

Zhou Ke's temper flared up again, which Li Aiguo thought was because Chen Shuxian was pregnant again and had been making him sleep on the sofa lately.

Li Aiguo stopped Zhou Ke and gave the toll collector the phone number of the Qianmen Locomotive Depot.

There was no telephone here, so the cashier called out to Nurse Zhou: "Zhou, could you please make a call to verify this?"

She kept her eyes fixed on Li Aiguo and Zhou Ke, knowing she would definitely have to deal with them later.

"No need, it's just a letter of introduction." Nurse Zhou knew that this kind of thing could be a big deal or a small deal, and she was a little worried.

"Make a call, Nurse Zhou." The cashier's temper flared up as well.

Nurse Xiao Zhou had no choice but to take the number and make the call.

"Excuse me, do you have a colleague named Li Aiguo in your locomotive depot?"

"What? He's the head of the studio? Oh, I see."

Nurse Xiao Zhou was also stunned.

It's rare to see such a young leader.

"Wow, she really is a leader. But what kind of organization is this studio?" The cashier still felt something was off after hearing what Nurse Zhou said.

Nurse Xiao Zhou glanced at Li Aiguo standing at the door and said, "Sister Wang, since he's a leader, let's hurry up and complete the formalities. The patient is waiting for his dressing change."

Hearing this, the cashier didn't say anything more. After taking the money, he asked Li Aiguo, "There's a cafeteria in the hospital. If you want to eat here, you'll have to pay 50 cents a day."

After thinking for a moment, Li Aiguo agreed, saying, "Let's buy half a month's worth of meal tickets first, even though Zuo Dongfang's injury wasn't serious."

The toll collector picked up the abacus and quickly calculated that it cost a total of over ten yuan, mainly for the meal.

After successfully paying the medical bills, Nurse Zhou retrieved the medication from the pharmacy and helped Zuo Dongfang change his dressing.

Upon learning that Li Aiguo had spent more than ten yuan, Zuo Dongfang felt even more embarrassed and wanted to stand up immediately.

"It's just a minor injury. I'll be fine after a couple of days of rest. I don't need to stay in the hospital for so long."

“Brother, even a broken bone takes a hundred days to heal, let alone a big hole in your stomach. Listen to me, get well soon, we have important things to do,” Li Aiguo said with a smile.

Zuo Dongfang was stunned when he heard this: "You're planning to deal with those wild boars?"

"That's more than a dozen wild boars, thousands of kilograms of meat!" Li Aiguo couldn't help but rub his hands together.

In the past two years, under the guise of training, the armed forces department of the Qianmen Locomotive Depot has hunted all the wild boars on the hills near Weizhuang Commune. Li Aiguo was worried about where to open up a new training ground, and this was delivered right to his doorstep.

Of course, it would be even better if we could catch that black tiger.

The scientific name for the black tiger should be blue tiger, also known as black-blue tiger.

Before liberation, there were records of black tigers in China. Missionary and big game hunter Harry Caldwell once hunted one in the Eastern Tombs.

Western missionaries also obtained two precious black and blue tiger skins by bribing the guards of the Western Garden.

Some say the black tiger is actually a Maltese tiger, while some domestic scholars believe it is a rare variant of the South China tiger or the Siberian tiger.

Because of the lack of live Black Tiger specimens, the matter has remained unclear.

The black tiger became extinct in later generations. The last time it was seen by people was in the 1950s, in Chenjiayu.

Now that Li Aiguo has encountered this opportunity, he naturally cannot miss it.

Zuo Dongfang was a little worried: "Those wild boars are too powerful, and that black tiger is an adult tiger, huge in size, too dangerous."

"Don't worry, we won't fight a battle unprepared."

Seeing that it was getting late, Li Aiguo told Zuo Dongfang to get some rest and that they would go up the mountain after the Qianmen Locomotive Depot's armed forces department had made arrangements.

Just as Li Aiguo and Zhou Ke were about to leave the ward, they were stopped by Nurse Xiao Zhou.

"Are you going up the mountain to catch wild boars?"

The nurse must have overheard their conversation. Li Aiguo raised his eyebrows slightly: "What?"

Nurse Xiao Zhou pursed her lips: "The wild boars in those mountains are not easy to deal with. A couple of years ago, when there was a shortage of food, the town organized a hunting team. They went up the mountain to hunt, and more than a dozen people were bitten by wild boars. They were all injured."

And that black tiger is even more formidable. My father is an old hunter, and he says that black tiger is the mount of the mountain god, and we must never catch it.

No wonder this girl was so concerned when she heard that Zuo Dongfang was injured while catching a wild boar.

Li Aiguo, however, keenly sensed something: "Is your father an old hunter? Can he take us up the mountain?"

Nurse Zhou pouted: "Do you think I would harm my dad?"

Hearing this, Zhou Ke was unhappy, but Li Aiguo quickly stopped him and said with a smile, "We just want to ask about the route in the mountains. Your dad doesn't need to go up the mountain. Do you know about instant noodles? If you agree, we'll give you five packs of instant noodles."

Nurse Zhou is young, and she was immediately tempted when she heard about instant noodles.

However, she only agreed to take Li Aiguo back, and wouldn't let her father accompany her up the mountain.

"Five packs of instant noodles, remember that."

"Do not worry."

Li Aiguo felt like a creepy uncle trying to lure a child with candy. He chuckled and turned to leave the hospital.

After returning to the Qianmen Locomotive Depot, Li Aiguo went directly to the Armed Forces Department and found Minister Niu.

I heard that not far from the capital, there is a large number of wicked wild boars that are causing trouble, harming the local area, and committing all sorts of evil deeds.

Minister Niu said angrily, "We've been liberated now, and there are still such despicable wild boars. We can't turn a blind eye to this! I'll arrange for men to wipe them out immediately."

"Comrade Lao Niu, we can't fight a battle unprepared. Let me go see that old hunter in a couple of days, and then we can set off." Li Aiguo handed Minister Niu a cigarette and explained the matter of Black Tiger.

Hearing that there were black tigers in the mountains, Minister Niu became even more excited.

"I didn't expect you to be so skilled in military strategy now. Alright, I'll listen to you this time and let those wicked wild boars and black tigers live a couple more days."

Minister Niu was also busy. He immediately wrote a report to his superiors requesting permission for a field training exercise, and then had the weapons prepared.

Pistols, rifles, light machine guns. When Li Aiguo saw Minister Niu ordering the mortars to be brought out, he quickly stopped him: "Comrade Niu, this really won't do. We just want to deal with those wild boars, not to get a bunch of wild boar paste."

“That’s true,” Minister Niu said, waving his hand at the team members. “Don’t bring the mortars, bring more hand grenades.”

Li Aiguo: "."

He felt sorry for the wild boars.

Of course, you can't use guns or grenades to deal with black tigers. Li Aiguo remembered that in later generations, zoos used tranquilizer darts to control tigers.

The current anesthetics aren't strong enough, so Li Aiguo plans to build his own net gun.

This thing is powered by compressed air. It uses the power generated by the instantaneous release of gas pressure to launch a large umbrella-shaped net with eight rubber bullets, which then wraps around any objects it encounters.

In later generations, it was often used as a restraining tool to control targets, and now it is most suitable for dealing with tigers.

After getting off work, Li Aiguo went to the equipment department of the meteorological station.

Net guns, as special types of firearms, should be manufactured by weather stations.

The equipment department team is also preparing to manufacture a piece of equipment that can subdue a target without harming it.

It can be used to deal with important targets.

After hearing Li Aiguo's idea, several team members immediately nodded in agreement: "This is a good idea."

"The net gun only needs to be able to fire and catch the net; it doesn't need to be complicated to aim or fire in bursts." Li Aiguo took out the design drawings he had worked on that afternoon.

The design is actually quite simple: a spring is inserted into a steel tube, one end is fixed to the rear of the gun body, and the other end is connected to a "net support".

The most crucial aspect is still the manufacturing of components.

Springs and steel pipes can be obtained from the locomotive depot; some scraps will suffice.

The traction rope was made of three strands of cowhide.

The key issue is the network structure; none of the members in the equipment department know how to create it.

Fortunately, one of the members of the Old Cat team was a fisherman who often wove fishing nets when he was a child.

When Old Cat called him to the equipment area, the young team member was quite excited: "Team leader, what important task do you have for me? I promise to complete it!"

The old cat pointed to the rope on the ground: "Make a fishing net."

Junior player: "."

Before joining the team, he needed to weave fishing nets; after joining the team, he still needed to weave fishing nets.

What is this thing called? !
