Siheyuan: I am Yi Zhonghai's biological son

Yi Ping'an knew nothing about the happy events in the courtyard. He didn't even know that he had become a father. He was so busy now that he didn't even have time to sleep or eat. Not to mention his family, even Wang Kaixuan could not easily see him.

Wang Kaixuan would go to the Siheyuan once every half a month and bring some special supplies from Yi Ping'an. Many of the special supplies were replaced with milk powder. This was Yi Ping'an's instruction. He didn't want his eldest son to starve.

Since taking on the mission, everyone in Group 101 has entered a state of ecstasy. Team Leader Tian showed Yi Ping'an the mission requirements of the chip. After Yi Ping'an read the chip parameters, he knew that he had guessed right, because these were the requirements of the aerospace chip.

The biggest difficulty of this chip is how to prevent radiation and adapt to extreme temperature differences, as well as defend against attacks from crazy high-energy particles to ensure the smooth operation of the chip program. However, with the current lithography technology, they cannot meet the requirements of aerospace chips, so the lithography machine must be further improved.

Finally, in March 65, a proximity lithography machine was developed, and the minimum process was raised to 3nm, which was the level of the 193s.

It is no exaggeration to say that we are far ahead in the world, which means that all the electronic products you saw in the 90s, we can now produce, and those who look down on us are only worthy of following behind us.

Even when the wind blows, Yi Ping'an is not afraid. No one will despise the benefits of earning foreign exchange.

The next thing is the chip's defense protection measures. Apart from providing space data, Yiping'an can't really help at all. We can only rely on these experts and slowly experiment on our own. However, this most difficult hurdle has not been overcome yet. The mood in the group has been very depressed recently.

Yi Pingan once again regretted why he didn't study aerospace in his previous life. He was so good at nothing. Apart from providing ideas and opening up his mind, he was useless. This made Yi Pingan a little depressed and he felt a little useless.

It just so happened that the remote control system he was responsible for also encountered a bottleneck, and for a moment he was stuck in a dead end, which made him a little irritable. Yi Ping'an also realized that something was wrong with himself and tried his best to suppress it.

Director Liu noticed Yi Ping'an's change immediately. Something was wrong. Was there something wrong with his mentality?

"Engineer Yi, are you too tired recently? Do you want to take a break?" Director Liu was afraid that if he continued to suppress his emotions like this, he would have mental problems. This is nothing new in the field of scientific research. Scientists and lunatics are often only one step away.

"Leader, I just feel that I am useless, a bit of a waste, and I can't help with many things. Now my thinking has also reached a bottleneck." Yi Ping'an smoked a cigarette with a somewhat depressed tone.

Director Liu: Do you want to listen to what you are saying? People like you are useless. How can others survive?

"Yi Gong, why don't you go back and see your son? The little guy is already half a year old and he still hasn't seen his biological father."

"Son? Yes, my son is several months old. It's already June. Leader, let me go ask Wang Kaixuan about my son first." When Wang Kaixuan told Yi Ping'an that he had a son, Yi Ping'an and the team were busy improving the lithography machine. He almost forgot about it after that.

"Kaxuan, when was the last time you went back to the Siheyuan?" Yi Ping'an found Wang Kaixuan and asked.

"Mr. Yi, I went back ten days ago." Wang Kaixuan replied.

"By the way, how is my son?" Yi Ping'an asked again.

"Engineer Yi, why don't you go back and take a look? The little guy is very healthy, plump and fair." Wang Kaixuan also knew that there was something wrong with Yi Ping'an recently, and the director had reminded him about it.

Yi Ping'an thought about it and decided that he might as well go back and take a look since his head was a mess.

So Yi Ping'an took a leave of absence and drove away from the institute with Wang Kaixuan.

As soon as he arrived at the cross-courtyard and before entering the door, he heard the laughter of children. Yi Ping'an felt his heart was filled and his irritability was much less.

I walked quickly forward and opened the gate, and saw an old lady busy in the vegetable garden. Meng Xiaoting was watching with a little kid in her arms. The little kid was laughing so hard that his saliva was dripping.

Hearing the sound of the door opening, the three of them turned around immediately and saw Yi Ping'an standing at the door, smiling at them.

"Ping An, you're back?" Two female voices sounded at the same time.

"You're back. Is this my son?" Yi Ping'an came to Meng Xiaoting, bent down and looked at the little kid. The little kid also looked at the stranger. His eyes were round and exactly the same as his mother's, and he just stared at his father without blinking.

Yi Ping'an stretched out his hands and wanted to hug him. This boy was really not shy. He stretched out his hands and leaned towards Yi Ping'an. Meng Xiaoting was shocked. Her son was not someone that could be found by just anyone.

Yi Ping'an held her son in her arms and looked at him carefully. He was fair, tender and chubby, and seemed to be well-raised. He looked like his mother and not like Yi Ping'an at all. She didn't know if he would change when he grew up.

"Do you know who I am?" Yi Ping'an held his soft son in his arms, feeling as if he was holding the whole world. It turned out that cubs are the most healing.

"Ah...ah..." The little kid can't speak yet, and he starts drooling as soon as he opens his mouth.

"Why is he drooling all the time?" Yi Ping'an asked Meng Xiaoting.

"He's drooling because he's about to grow teeth. He really likes you and won't let anyone else hold him." Meng Xiaoting said with a smile.

"What's so strange about this? We are father and son." Yi Ping'an said with a smile.

Yi Ping'an was holding his son in the yard and talking to two women. They basically asked questions and Yi Ping'an answered. The little boy just stayed quietly in his father's arms, without making any noise.

"Haha, this kid is easy to coax. He doesn't cry or make a fuss." Yi Ping'an said.

"Indeed, as long as he is not hungry, he will not make trouble. Ping'an, it's a good thing that you are back, so give your son a name. Dad has given him a nickname and told you to choose a real name since you are well-educated." Meng Xiaoting said.

"What's your nickname?" Yi Ping'an asked, hoping it wasn't something like Goudan.

"My nickname is Tietou. My dad said Tietou is tough and easy to raise." Meng Xiaoting said.

"Hahaha, it's really tough." Yi Ping'an said with a smile. As long as it's not Goudan or something like that, he can accept it. "As for the full name, let me think about it. I thought dad had already given it a name." He refused to admit that he had forgotten.

"Okay, but don't be in a hurry. We still have to register him. Just use a nickname now to get a quota, so that people won't call him Yi Tietou in the future." Meng Xiaoting reminded.

"Don't worry, I'll think of it tonight." Yi Ping'an said. How complicated can it be to come up with a name? At most, you can just look it up in the dictionary.

When Yi Zhonghai came back from get off work, he was very happy to see Yi Ping'an back, but he only asked, "How are you? Don't get too tired." Then he picked up his eldest grandson and asked, "Does Tietou miss grandpa?"

Yi Ping'an: So love will disappear? Now that you have a grandson, your eldest son is no longer important.

Forget it, Yi Ping'an returned to the room and quietly replaced the milk powder that Wang Kaixuan brought for Xiao Douding with the milk powder in the space. He didn't have the chance before, but he has the chance this time. He will put more in when he leaves. Xiao Douding's body and brain are both important, so the milk in the space is better, and he needs to be supplemented from a young age.

In the evening, after Yi Ping'an and Meng Xiaoting had an in-depth conversation, Yi Ping'an whispered in Meng Xiaoting's ear, "I'm going out for a while, please leave the door open for me."

Then Yi Ping'an put on a set of black clothes, wrapped himself tightly, went out, and scanned with his mental power. He found that everyone in the yard was asleep, including Wang Kaixuan. Yi Ping'an jumped out of the yard.

Today, after Yi Ping'an left the research institute, he found someone following them, but Wang Kaixuan did not notice it, so Yi Ping'an did not tell him. It was really difficult to explain why he could notice this, so he could only put a mental mark on the person who was following him.

Now Yi Pingan followed the sign of his spiritual power and found that the man was not far from his home, just two streets away. At this time, he was talking to a few people in the basement. Yi Pingan quietly approached the basement and found that those people were saying:

"Kojima-kun, did you find anything today?"

"Koizumi-kun, I saw someone coming out of that place today. I followed him all the way and found that he went to a yard over there. But there was someone next to him, so I didn't get close to him."

"Do you remember which yard it is?"

"remember."

When Yi Ping'an heard this, he realized that this wouldn't do. This was not aimed at him, but at the research institute. How shameless! Yi Ping'an directly threw a fog egg in. This was a drug in space. Not to mention humans, even elephants could be knocked out by the drug.

I haven't done this for several years. I had almost caught all of them, but they appeared again. It's just like cockroaches. I can't get rid of them. So I started to break glass. I haven't broken glass for a long time.

With a crisp sound of "pop", a small stone passed through the glass and entered the house. Yi Ping'an smiled and ran away using his Qinggong.

Back at the courtyard, Meng Xiaoting was carrying more than a dozen cans of milk powder in her hands. She was not worried that her eldest son would not have anything to eat in the short term. She didn't ask anything, just put the milk powder in the cupboard and went to sleep.

After staying at home for two days, he named his eldest son Yi Zhixin. Looking at the innocence of the cub, Yi Ping'an was once again motivated. Even if it was for the sake of his son's future so that he would not be a slave, he must develop technology into a leader.

On the morning of his departure, Yi Ping'an kissed Tietou on the head as he fell asleep, and then left the house. He felt worried and motivated. If the predecessors could fight the battle of three generations with one generation, I could do it too.
