Qin Hongfei was surprised: "It's not a nuclear weapon?"

Tu'er said calmly, "Yes, it's not a nuclear weapon. It should be a system to intercept nuclear weapons. The defense system is used in military research."

Qin Hongfei was really confused. She handed the blueprint to Tu'er and they had been studying it as a nuclear weapon, but now they said it was not a weapon, but a defense.

Tu'er gave her a suggestion and took the blueprint to find Mr. Li.

She went home and took out her father's blueprint to look at it. Only half of it was related to nuclear weapons from the parts, but she did not associate it with defense missiles.

After thinking about it, she took the blueprint to find Li Jiantian. Li Jiantian was not in the institute. He was invited by the coastal engineering team to do data inference. Qin Hongfei went to the location to find him. She saw Li Jiantian wearing reading glasses and surrounded by people, explaining the data theory and principles to the people around him one by one...

When he went up the stairs, his steps stumbled.

Qin Hongfei said cautiously.

I found out that these people in the institute are actually very old. The youngest is Mr. Li, but Mr. Li is also in his seventies. Mr. Cang is in his eighties. They should have retired long ago, but they were re-employed by the country. They have been busy contributing their abilities and hoping that China will become stronger and stronger. It's amazing.

She thought with emotion, and over there, Li Jiantian felt uneasy when he saw her, so he arranged for someone to ask her to stay in a room. Qin Hongfei was a stranger, which aroused the curiosity of many people.

Ten minutes later, Li Jiantian came over.

Qin Hongfei saw him and couldn't help but say, "You should pay attention to rest."

Li Jiantian didn't like it: "Little girl, you are so young, don't learn to be as nagging as your teacher and Lao Cang. I'm in good health."

Qin Hongfei reached out to take his pulse and said, "You haven't slept well for a few days. Your heart pulse is so weak. Do you feel stuffy in your chest?"

She was right.

Li Jiantian was secretly surprised! How long has this little girl learned?

Two years?

She can take the pulse and diagnose in two years.

However, he refused to admit it and said flatly, "At our age, how can our health be so good? We have some problems, don't be surprised."

Qin Hongfei was speechless and said, "Stop making excuses. You just feel that you are old and you should be busy as much as possible, otherwise you will die if you lie down."

Li Jiantian had a toothache. Why did he say it so directly?

Qin Hongfei said, "You are over 70 years old now. If you take good care of your body, you can live for more than 20 years, to 100 years old. Take care of your body and live well. Wouldn't you be able to contribute more to society this way?"

Li Jiantian felt annoyed and wanted to get rid of him. He changed the subject and said, "Why did you come back to see me?"

Qin Hongfei saw that he changed the subject and couldn't help staring at him.

Li Jiantian felt guilty being stared at, but he pretended that he was not guilty at all, "Hurry up and tell me, I have to go to work..."

Qin Hongfei frowned and pondered for a while, and finally took out the blueprint, "I want you to help me look at this."

She spread out the assembled blueprint.

"Teacher Li, take a look at the design on this blueprint. Does it look more like a nuclear weapon or a missile defense system?"

"The one from your father?" Li Jiantian just remembered that he had never seen this thing. It was said to be the half-drawing left by Qin Jiangke, and Bai Qishi also tried hard to get it.

"Hmm..."

Li Jiantian picked it up and examined it for a while before speaking, "It looks like a nuclear weapon."

Li Jiantian had participated in the production process of Chinese nuclear weapons. He was a deputy engineer and knew the structure of nuclear weapons very well. "No, it looks like one, but it's not."

"As for the interception system, this one is a bit like one, but it's also a bit wrong..."

Li Jiantian muttered, staring at the drawing. The more he looked, the more his pupils enlarged. He muttered something in his mouth, and then quickly asked hurriedly, "Where is the other half of the drawing?"

Qin Hongfei: "..."

"No."

"Only this half of the drawing, the other half should be with Bai Qishi."

This is what she guessed.

Li Jiantian was anxious, "Why is it with that grandson, and Zhou Yiming snatched it?"

Qin Hongfei: "………………"

She just looked at him silently.

Li Jiantian sighed, "Okay, don't look at me like that, I know it's not realistic.

" He said unwillingly, "The structure of this drawing is indeed strange. It looks like a conventional nuclear weapon, but the core part is not. If you say it is a missile defense system, that's a bit strange... I always feel like something is wrong. If I had a complete drawing, I might be able to figure it out."

Complete drawing!

Qin Hongfei didn't have it.

Her eyes flickered slightly, "Teacher, from your perspective, how likely do you think this drawing is to be a defense system? My mother said before, and my father said that the possibility of a nuclear weapon is not high."

Ms. Xia said.

Qin Jiangke would not deal with atomic bombs or other things that hurt people. Even if he saw something sharp on the road, Qin Jiangke would deal with it for fear of hurting innocent passers-by.

Li Jiantian took a deep breath, "If what your mother said is true, and if it was really done by your father, then this thing is very likely to be a defense system! If it is a defense system, it would be terrible..."

The defense system does not refer to the conventional anti-virus system on the computer, but is used in the military.

Its early warning satellite and radar can automatically capture infrared signals in the air and transmit data to the rear, and then judge the flight trajectory, target, and landing location of the opponent's missile. Combined with all the data, interceptor missiles are launched to deviate from the target of the missile. In military combat, the defense system can play a very important role, especially when deployed in air combat.

China currently has such a system - but it is lacking.

Li Jiantian looked at Qin Hongfei with a fiery look, "If this was really made by your father! I can only say that your father is really amazing!"

Really!

It's amazing.

Li Jiantian's brain can't make such a thing!

What kind of brain structure is needed to make this.

This branch of the Qin family!

Qin Hongfei also heard from Mr. Li's tone that this thing is really incredible.

So it is really a defensive missile, not a nuclear weapon.

Li Jiantian glanced at her, hesitant to speak, "Xiao Qin..."

Qin Hongfei raised her eyebrows, Xiao Qin is fine, and Xiao girl is fine, but she probably knows what Li Jiantian is thinking, "Teacher wants to keep the drawings for research?"

Li Jiantian coughed dryly, thinking that this was left by someone's father, and it would be a bit unfair for him to take it, but...

Qin Hongfei said, "Teacher, if you want to research, then research it. If you can really research it, it will be great." She said.

Li Jiantian said, "But this is not left by your father..."
