The matter was forcibly decided by the old man, and Zhang's mother is still emotional, which needs to be explained and appeased by Zhang's father. Zhao Ting also had a lot of questions, so she pulled Li Guocheng to the guest room.

"What the hell is going on? Why did grandpa make a decision, there was no sign before". Zhao Ting asked impatiently as soon as she entered the guest room.

Li Guocheng briefly explained the situation in the study, and he didn't expect the old man to be so interested in machine tools, so he loved the house and Wu, and successfully got the old man's affirmation.

"And what about my dad's opinion?"

Zhao Ting suffered from gains and losses, and she didn't want to have a stiff relationship with her parents before, so she hid out under the pretext of work.

"Your dad shouldn't object", although he didn't object, Li Guocheng also felt Zhao's father's rejection and suspicion of himself, but the old man was very strong, so he didn't make a clear statement. It was useless to say his feelings at this time, and it made Zhao Ting worry in vain.

finally let go of the burden of family opposition, but Zhao Ting began to worry about herself.

"I'm so ugly, are you really willing to marry me?" Zhao Ting touched the scar on her face, she had no hope before, she deceived herself, she got by, and she didn't dislike Li Guocheng, as long as the other party was willing, just deal with it. Today, with the support of the old man, she began to think seriously about the future.

Li Guocheng stepped forward to hug her and kissed him on his scar.

"This is the medal you have paid for the country, I only have admiration, only admiration", Li Guocheng looked at her affectionately.

Li Guocheng was about to make further movements, but was gagged by Zhao Ting with his small hand.

Hearing Li Guocheng's answer, Zhao Ting was very moved, but there was still a knot that had to be untied, after all, the next thing was for the two to really live together.

"I want to make one thing clear to you again, my current job is characterized by being very busy and potentially dangerous, would you still be willing?"

"How many times have you asked, I, Li Guocheng once again solemnly reiterated, in the future, when you go on a mission, I will wait for you at home, if there is danger, I will fight with you."

Although Zhao Ting has heard similar answers many times, she feels even more moved today. She hesitated, lowered her hand, and slowly closed her eyes.

Li Guocheng would hesitate and kiss him directly.

With the stalemate of the battle situation, Li Guocheng actually thought of opening up a second battlefield, took the lead in charging at the opponent's fruit stall, and attacked and defended each other, and finally occupied the position.

I don't know how long it took, the flushed Zhao Ting pushed Li Guocheng away, habitually kicked Li Guocheng's calf with her toes, and was ashamed to give him an over-the-shoulder fall.

Li Guocheng provoked a war again, and Zhao Ting, who had regained her senses a little, hurriedly stopped it.

"Grandparents, Mom and Dad are downstairs!"

Li Guocheng also accepted it when he saw it, knowing that Zhao Ting had a strong temperament and thin skin, so he didn't dare to be too persecutive.

After repeatedly promising not to be strange, Zhao Ting was reluctantly hugged by Li Guocheng to her lap.

"I'll give you a big gift in a few days," Li Guocheng said mysteriously.

After lunch, the three men came to the study again.

"You mentioned semiconductors in the morning, and you have mentioned it many times in the recent meeting, tell me your opinion", the old man took over the topic again.

"In some translated magazines, there has been a prospect of computer applications, believing that in the future, computers will enter all walks of life, and whoever masters computer technology will be able to take the lead."

"Today's computers are too large, and the power consumption is also large, and it is difficult to popularize them", Zhao's father has understood domestic computer technology at a glance.

What Zhao's father mentioned should be that in 1959, China imitated the Soviet Russian БЭCM-II computer and developed 104 machines, with a speed of barely 10,000 times, but due to the assembly of 4,200 tubes and 4,000 diodes, covering an area of more than 400 square meters, the tubes are often damaged and the reliability is not high.

After the 104 machine was delivered to the aerospace and military departments, it completed a number of scientific research calculations for a number of major projects.

Although there is still a big gap between the performance of the 104 machine and the RCA501 computer in Chouguo, it is almost the same as the level of computers such as Parrot and RB that started in the same period.

"Yes, the current computer is indeed huge, but now the emergence of transistors can greatly reduce the size of the computer, will also greatly reduce the power consumption, and the reliability synchronization will also be increased by several orders of magnitude."

Li Guocheng saw that the two were interested in computers, organized language, and wanted to influence them, so that the upper echelons would pay attention to computers and avoid the continuous backwardness of future generations.

"If I'm not mistaken, the 109B machine is a transistor computer, and the investment is too large, and it is only used for key national defense projects, and it is too difficult to popularize it. Our country is still too poor, foreign exchange is also scarce, the most important thing now is to solve the problems of the national economy and people's livelihood, and now the investment in computers is unsustainable."

Zhao's father didn't look down on Li Guocheng either, after all, the 109B machine was still in the testing stage, and ordinary people couldn't get it. Since he was forcibly slapped by the old man, Zhao's father just used these non-confidential contents to beat him.

I didn't expect Zhao's father to have such a deep understanding of computers, Li Guocheng thought that China did not continue to study computers at this stage, but he knew that history, from now on, China's computer technology began to widen the gap with foreign countries, and it is getting bigger and bigger.

When I was in college, I seemed to have heard a teacher say that Huaxia's scientific research and technology in this era were mainly for the purpose of serving national defense science and technology, and only a large investment did not produce social and economic benefits, and the burden became heavier and heavier, so we had no choice but to reduce investment year by year.

Thinking of this, Li Guocheng was even more excited, since there are already transistor computers in China, as long as they can be persuaded and supported by them, chip research and development can continue.

"We can think differently, now the country only invests in computer research and development, there is no economic return, if we use computers for civilian use, improve production efficiency, improve the scientific and technological content of products, this will produce direct economic benefits. If the product is excellent, you can also earn foreign exchange".

"That's impossible, the current computer is too expensive, and too delicate, it's okay to engage in scientific research and computing, don't think about anything else."

Zhao's father and they have held many meetings to discuss the application of computers, but in the end there is no good way but to reduce the investment.

"What if you integrate a computer into a module?" Li Guocheng put forward the concept of single-chip microcomputer ten years in advance.

"How is this possible?!".

"It's completely feasible, the main reason why computers are large and low reliability today is that the transistors are discrete, and they are connected by wires, which are easy to pollute and damage.

In our army's three-three system, the smallest combat unit is a squad, with three squads forming platoons, three platoons forming companies, and companies forming regiments, brigades, divisions, and armies until they form military districts. If the functions of a computer are broken down into small modules, each module completes a function, and the small modules form large modules until they form a computer.

Dozens or hundreds of transistors are prepared on a wafer that produces transistors at the same time, and they are connected with metal wires to complete one or more minimal functions, and then packaged in ceramic or plastic, so that the volume will be much smaller and the anti-pollution ability will also be improved.

With the maturity of technology, it is completely possible to concentrate all these functions in a large module, which is only as large as a cigarette box and matchbox, and can it be used for people's livelihood, such as automatic control of machine tools."

Li Guocheng said directly, and the two of them seemed to be achievable when they thought about it, and they were full of excitement.
