Originally, the training of the personnel of the iron and steel plant did not require the minister of military industry, but Liu Peng could only put down the work at hand and follow the preparatory personnel of the iron and steel plant to Jiuquan together.

Liu Peng, who was idle and bored, began to listen to the lectures with the students.

After listening to a few verses, Liu Peng began to take notes.

At the beginning, the lecturer of Jiugang still taught steel smelting, although it was slightly more detailed than the metallurgical course he had studied, but it was also within Liu Peng's knowledge system, and it was effortless to learn.

Then, on the basis of steelmaking, the lecturer gradually incorporated some simple alloy smelting knowledge, and then began to add special steel smelting knowledge to it little by little......

Liu Peng began to congratulate himself that he was not a "thorn".

Before the excitement of learning about special steel smelting passed, Liu Peng discovered a "new continent": when the lecturer explained steel rolling, he interspersed some common sense of metal processing technology......

As a result, Comrade Liu Peng thoroughly threw himself into the "embrace" of metallurgy......

Although most of the interns sent by Yanzhou are college students with a certain metallurgical foundation, it took more than two months to complete the theoretical knowledge related to steel smelting.

After the metallurgical theory mapping exam, the trainees began to operate in the field.

During the practical operation, Liu Peng was shocked again: when his own students operated, JISCO matched everyone with an instructor and taught one-on-one.

When the trainees were practicing in three shifts, Liu Peng was not idle, and when he had just finished teaching the theoretical knowledge of metallurgy, Liu Xuanying gave him a box of thick materials: the design materials and processing technology of the Jiuquan "fine imitation" Japanese weapon......

What interested Liu Peng the most was the 70 mm and 75 mm ammunition technology for the Japanese Type 92 infantry gun and the Type 94 mountain gun: these two types of artillery were captured by the 115th Division during the victory at Pingxingguan, and later due to the lack of ammunition replenishment, some of the artillery pieces were directly melted down.

After carefully studying the production process of the two types of ammunition, Liu Peng found that with the current industrial level of Yanzhou, except for gunpowder, others can basically be produced by themselves; Even the most difficult fuzes to process are no longer a problem because of the newly acquired equipment.

Just when the personnel of the Chinese Communist Party were constantly absorbing new knowledge and making great progress every day, Liuyun received news from Liu Xuanhui, who was far away in Jiayuguan: polysilicon of 49 purity can be produced in small batches......

More than a month later, researchers at the Semiconductor Research Center in Jiayuguan removed a six-inch-diameter monocrystalline silicon rod from a monocrystalline furnace.

After cutting, the monocrystalline silicon wafer is turned into a chip through oxidation, photolithography, diffusion, epitaxy, aluminum steaming and other processes in a fully automatic workshop......

Looking at the packaged LSI in the box, a smile appeared on Liuyun's face......

A little more than a month later, all the designers at the Jiuquan Industrial Base began to distribute electronic calculators, and each project team was equipped with a projector of unknown purpose in the office area.

In the underground computer room of the Jiuquan Industrial Base Technology Center, Liu Xuanying was a little speechless when he looked at his father, who used a large number of large-scale integrated circuits that he had worked hard to drum up as accessories to match his own "hand-rubbed" central processing unit......

But what made Liu Xuanying even more speechless was that after the assembly was completed, the giant guy who didn't respond at all when plugged in the power supply sounded "buzzing" after the old man waved his hand......

What is this operation?

What surprised Liu Xuanxuan even more was still to come......

"Search the database!"

With the old man's command, a line of words appeared on the screen of the energized color monitor: After searching, the database is empty.

Then Liuyun waved his hand again and gave the command "Search Database" again, and different results appeared on the monitor: after searching, the following data was detected in the database......

Liu Xuanying stared at the names of the long list of materials that appeared on the screen with bright eyes, and she didn't even notice that her saliva was dripping on the ground.

After that, Liuyun demonstrated the use of the projector again, and after the demonstration, he threw Liu Xuanying a manual and left the computer room.

With the supercomputer, many of the projects in the technical center are moving forward quickly.

The 201 Institute, which received the task book for the high-altitude and vacuum liquid rocket launch project, completed the calculation in just over two months and passed the computer simulation verification.

Just when the people of the 201 Institute were celebrating the expected success of the project, Liu Xuanliang, the leader of the 201 Institute, received the internal documents of the 1021st, 1022nd and 1023rd Institute of Electronics in Jiayuguan: the three newly established research institutes are responsible for the research and development, application and manufacturing technology of semiconductor computers.

Not long after, Jiuquan established the sixth No. 203 Institute with numbers in Northwest China, which was responsible for the research of precision optical instruments......

As soon as we entered Layue, although it was already cold and windy in the northwest, there was no chill at the rocket engine test site located in Qilian Mountain.

In the control room, wrapped in thick armor, thermal insulation and bulletproof glass, Liu Xuanliang stared nervously at the bright red countdown on the wall......

30、29…… 10、9……

When the timer ended, there was a round of applause in the control room......

Liu Xuanying immediately announced that the rocket engine finalization test was completed and the model was officially finalized.

The technicians waiting behind the console cheered: thousands of uninterrupted trials had finally ushered in the dawn of success......

While everyone was cheering, no one had the idea, and someone pushed open the thick iron door at the back of the laboratory......

"Dissolve red, anti-red, limit red, anti-red......" Looking at the text on the telegram, Liuyun smiled, "Dogs can't change eating!" ”

After speaking, Liuyun looked at Liu Xuanying, who was paying attention to him: "Within three months, the satellite will go to the sky!" ”

Seeing that his old man's face was not good, Liu Xuanying kept drawing circles behind his back, cursing and scolding the fucker who blocked himself......

Liu Xuanzhi, who had been with his old man for a long time, naturally knew how to avoid "rainy days", took out another telegram from the folder, and handed it to Liuyun: "Dad, this is sent by Xuangong." ”

"Yo, then I have to take a look, this kid is asking for merit and reward again?"

Liuyun took the telegram and looked at it, and was happy: "Not bad! ”

The content of the telegram was very simple: I prevented the anti-resistance group from attacking Zhou Shuren and his brother.

Liu Xuanzhi nodded: "That is, in the past year or so, the eighth has taken a large number of assassination equipment from us, and more than a hundred have been taken away from the muffler alone. ”

As soon as he heard more than a hundred mufflers, Liuyun was stunned for a moment, and then laughed: "Xuan Gong, this little rabbit cub, likes to hoard things like a squirrel, and he can't change it." ”

Liu Xuanzhi glanced at Liu Xuanying, who was bitter and hateful, and asked Liuyun with a smile: "If we have satellites, will we be able to know the battlefield situation well?" ”
