Dreaming back to 1949, the great powers were there to deceive us

As soon as Hu Zhenhua returned to Chongming, he urgently met with Jiang Zhen.

"I've received information through special channels that several of Polar Bear's key figures lurking in the United States may have been exposed. They involve atomic energy. Please notify the relevant authorities immediately to see if remedial measures can be taken!"

Jiang Zhen stood up and immediately said,

"I'll report it immediately!"

Seeing Jiang Zhen about to leave, Hu Zhenhua quickly grabbed his hand.

"The information can be given to them for free, but if you want further intelligence, you'll have to pay real money. Do you understand what I mean? For example, we could ask them to provide assistance to a few fertilizer plants."

Jiang Zhen nodded slightly.

"I understand! Can you tell me the source of this information?"

Hu Zhenhua smiled but said nothing.

Jiang Zhen didn't ask any more questions and turned away.

Trust is a wonderful thing. Some people can trust each other, while others can sleep in the same bed but have different dreams.

After receiving the notification, the Polar Bears discussed it and put the intelligence aside. They believed that this was false information deliberately released by the United States in order to alert the enemy and lure their own undercover personnel into revealing their flaws.

It is impossible for the Red side to obtain relevant information.

Last time, there was a guy called Y2K who made alarmist remarks, saying that the Americans were going to take action. But it turned out that the Americans did not take any unusual actions at all.

Hu Zhenhua no longer paid attention to this matter. Trust is built step by step. He doesn't care whether the polar bears believe it or not. Those stupid bears cannot be judged by common sense. They have always only believed in their fists.

Lao Hu has more important things to do. At this moment, he is walking in an underground passage, accompanied by Guo Dachong.

After the two walked about a thousand meters, Lao Hu suddenly stopped.

"This is?"

The surrounding walls are arc-shaped and were obviously artificially excavated and reinforced.

Lao Hu gestured and said that the width of the passage was at least five meters!

His heart was beating violently and his pace quickened.

Shield machine!

It must be a tunnel boring machine!

Three kilometers later, there was a fork in the road. Vehicles were constantly transporting soil and rocks to another channel. Further away, Lao Hu could already see the conveyor belt.

This is very similar to the shield machine of later generations.

Hu Zhenhua and Guo Dachong did not move forward until the machine in front stopped working.

"Is Dr. Jiang here?"

An engineer heard this and replied calmly,

"Mr. Guo is here"

He turned and shouted,

"Xiao Liu, go call Lao Jiang!"

After saying that, he lowered his head to study the drawings in his hand.

These people don't seem to care about Guo Dachong's position as vice chairman at all.

Soon, an engineer wearing a hard hat jumped down from the shield machine. He was covered in dirt and his clothes were stained with oil.

"Vice Chairman Guo!"

The man shouted something and then turned back to tell his assistant a few words.

Guo Dachong didn't mind and said with a smile,

"Dr. Jiang, the chairman is here to visit everyone!"

Before Lao Guo could speak, Hu Zhenhua had already stepped forward quickly. As soon as Lao Guo finished speaking, he had already held Jiang Yunhai's hand.

"Dr. Jiang, you're progressing too fast!"

Under the dim light, Jiang Yunhai leaned closer to Lao Hu's face and exclaimed,

"Chairman, it's really you!"

"It's me, I guarantee it's true!"

Jiang Yunhai suddenly turned his head back and shouted,

"Everyone come here, the chairman is here to visit us!"

Then, he emphasized one more sentence:

"It's not Chairman Guo, it's Chairman Hu Zhenhua!"

The engineers who had been hesitating were a little confused at first, and then showed ecstasy. They put down their work and gathered around.

Hu Zhenhua shook hands with them one by one.

There were about 20 engineers present, and the rest were workers, about people.

"Chairman, were you really stabbed in the back in Hong Kong?"

An engineer stared at Lao Hu's belly and asked this question.

Hu Zhenhua laughed heartily, unbuttoned his windbreaker, lifted up his underwear, exposing his belly, and turned around so that everyone could see it clearly.

There was a knife wound on Lao Hu's stomach and back, the front one was wide and the back one was narrow.

Of course you have to do the whole act, otherwise it will be easy to be exposed.

Jiang Yunhai saw it clearly and said quickly,

"Chairman, be careful not to catch a cold!"

This place is deep underground and the temperature is still very low.

Jiang Yunhai stretched out his greasy hands and helped Lao Hu pull down his clothes.

An engineer said,

"Chairman, I heard that you dealt with those arrogant gentlemen and left them staring blankly. Is that true?"

"Of course it's true. The Anglo-Saxons are nothing special. As long as we work hard and develop, we will surpass them one day!"

Everyone applauded excitedly.

Jiang Yunhai held Hu Zhenhua's hand and said excitedly,

"Chairman, with your leadership, I believe Tongan will prosper!"

Old Hu also held Jiang Yunhai's hand tightly.

"History has proven that science and technology are the primary productive forces. If China wants to revitalize, engineers like you will be the main force! The head office will safeguard your scientific research activities!"

Jiang Yunhai's hands tightened.

Guo Dachong stepped forward and patted him on the shoulder!

"Dr. Jiang, please tell me about the progress of the shield machine."

Only by talking about work can I divert his attention.

Jiang Yunhai wiped the tears from the corners of his eyes and said,

"We are researching an electric hydraulic shield machine with a diameter of 5.8 meters. We are currently experiencing frequent problems. The main technical difficulties are in four areas: first, the quality of the large bearings does not meet the standards; second, the cutterhead wears too quickly; third, debugging is difficult; and fourth, it is difficult to achieve precise directional control."

Hu Zhenhua frowned and asked,

"Why is it 5.8 meters? Can't the diameter be reduced?"

"Reducing the diameter is one solution, but a smaller diameter won't be as versatile. Take the subway, for example. It needs to house various pipes and ventilation equipment. A smaller diameter would make later construction very difficult. Tongan is researching shield machines to build underground facilities, so they can't be too narrow. Furthermore, our initial research goal was 5.8 meters. If we give up, all our previous investment would be wasted. Chairman, do you know how much we spent on building this prototype?"

Jiang Yunhai made an eight gesture,

"A full eight million Mi Yuan!"

Hu Zhenhua fell silent. Even the country fifty years later had to work very hard to develop a tunnel boring machine. You know, by that time, science and technology had made great progress.

Isn’t it a bit ahead of the times to launch the 5.8-meter diameter one now?

Bearings involve materials science, and it is not easy to make breakthroughs.

"Dr. Jiang, I have a suggestion. You should reduce the diameter to just enough for trucks to run! Let's take it one step at a time!"

Jiang Yunhai looked back at the machine behind him, his eyes full of reluctance.

Hu Zhenhua saw what he was thinking and said,

"Of course, you can continue your research on this as well, without delaying either!"

Jiang Yunhai and the others exchanged glances, and after a moment, he said,

"That would require another round of funding. The group has already invested so much in the machinery factory that I'm embarrassed to ask for more."

Guo Dachong immediately patted his chest and promised,

"Dr. Jiang, you don't have to worry about the funding. No matter how difficult it is for the group, we will raise this money!"

"Then let's give it a try, Chairman. I promise you that within ten days, we'll have a prototype ready!"

Lao Hu held his hand.

"Dr. Jiang, the government will not impose time limits on scientific research activities. Everything must be done according to scientific principles!"

"Yes!"

Hu Zhenhua tilted his head and thought for a while, trying to recall more details. After about five minutes, he gave up. When it came to specific techniques, he was a poor student.

"Don't we have a bearing factory in our industrial zone? Do they have a solution?"

Jiang Yunhai immediately replied,

"We've already commissioned them to handle the technical PR. If it weren't for the comprehensive range of factories in the industrial zone, we wouldn't have been able to build this prototype so quickly."

Speaking of a complete range of products, Hu Zhenhua suddenly remembered something. Since the industrial zone relaxed its access restrictions two months ago, he wondered what the current situation was like.

"Zhuge, go back to the county government and get some data. I want to see how many companies have settled in Chongming recently, and what specific industries they are in."

"Yes! Zheng Xipo has been wanting to report to you for a long time. He has encountered many difficulties recently and wants to hear your opinion."

Hu Zhenhua glared at Zhuge Lin.

"Watch your words! Zheng Xipo is the county magistrate, and our TA company is just a business under his management. What is he reporting to me? Is there anything he can report to me?"

"Yes, yes! It was a slip of the tongue, a pure slip of the tongue!"

Hu Zhenhua turned his attention to the shield machine and said calmly,

"Dr. Jiang, machines like shield machines are generally disposable, so when you design them, it's best to consider whether there are parts on them that can be disassembled and reused."

Jiang Yunhai pondered for a moment and said,

“Not a good deal!”

"Is that so? Never mind!"

Among the four difficulties, the cutter head involved materials science, which Hu Zhenhua could not help with, and debugging involved system engineering, which Hu Zhenhua was still powerless to do.

He thought about it for a long time and could only come up with some ideas on digging direction control.

Later generations mostly used GPS positioning or laser guidance systems for direction control.

Currently, neither of these methods is available. The atomic clocks used in the GPS system must be accurate to the nanosecond, which is simply impossible with current technology.

Laser technology, however, did not exist in this era! To be precise, it was invented in 1960.

Hu Zhenhua thought for a moment and said,

“Is the shield machine equipped with a gyroscope?”

An engineer immediately replied,

"It's installed, but there seems to be a discrepancy between the coordination of the various systems. We're trying to find the cause!"

Hu Zhenhua suddenly felt overwhelmed. These were the only methods he could think of, and the rest were all stupid methods.

For example, during the construction of the Red Flag Canal, the people had no measuring equipment, so they invented a duck measuring instrument. This device is very simple. You just take a basin of water and put the duck in it.

A "water duck" is actually a homemade level. It usually consists of a wooden stick and a water tank. When using it, the stick is inserted into the water and the level of the water in the tank is observed to determine the height of the terrain.

Hu Zhenhua was having a headache when he suddenly saw an engineer next to him take out an instrument. After asking, he found out that it was a level.

Hu Zhenhua shut up decisively. He didn't plan to make any more random suggestions. It would be a bit like showing off his skills in front of this group of engineers.

After chatting for a while, Hu Zhenhua went to visit another key project: the excavator.
