"That's it."

Chu He nodded to the grandparents and grandchildren, put the blackboard bricks back, and sat back on the dining table obediently, waiting.

What?

What's here?

Why is it here?

Professor Zheng was still confused. Xiaoxuan had already started to grop on the ground, and soon he touched the millet grains of similar color to the ground from the uneven concrete ground:

"Grandpa, is that right?"

Professor Zheng opened his eyes wide and looked over: It’s true!

The gray small screws were really inconspicuous in my grandson's gray palm! Fortunately, I found them. Their country does not have enough technology. Such special precision parts are all rubbed by a level 8 technician. If I lose this one, I will have to wait for a long time next. I don't know how much it will take to delay.

Wait a minute!

The focus now is no longer this small screw.

"How did you find it?"

He looked at Chu He, his drooping eyelids were supported by surprise.

Chu He:?

She said naturally: "I see that there are parts on your desk, so I just happened to get a sensor out. I have to lie on the ground to look for it. Not only is it dusty, I can't find it. When I eat later, the food will be cold."

After saying that, he looked at the food beside him looking forward, very enthusiastic.

"Come on, wash your hands and have a meal."

...

Now it's not a matter of food.

Professor Zheng immediately fell back to the table and tossed and turned to look at the strange blackboard brick.

What is done is really rough.

All the parts on the desktop were put together and they were pieced together. When Professor Zheng picked it up, he was afraid that he would accidentally let it fall apart.

Look at the connection points inside, there are several parts that do not match with high matching requirements. They rely entirely on a lot of effort to deform it, so a corner of the dangerous card is used to complete the connection...

If this is really the finished product, it will be scrapped if it doesn't take it twice.

But the question is, is it half an hour since Chu He entered the door?

Even if he was forced to put things together, he would not be able to do this for the rest of his life.

Oh my God!

The life-saving benefactor is such a genius!

How many talents has the country delayed!

He lay on the table, loving the blackboard bricks in his hand, and analyzing each part and the role played by the other party-

Magnetic induction, infrared detection...

!!!

Infrared detection! Micromagnetic beam sensing!

This is also Professor Zheng’s current direction. It took them a long time to apply for it, and the country had difficulty getting an infrared detection component from abroad...

But the problem is, it's just basic materials!

How to use, how to combine... I haven't thought about these yet, why can this be done directly today?!

Professor Zheng's eyes shone brightly, and he seemed to see the dawn of the project.

However, when Shuguang turned his head again, there was an empty bowl in front of him, staring at him with his grandson with a bad look.

...

As a binder for adult emotions, Xiaoxuan feels that he has endured too much at such a young age.

Seeing that the low pressure on Teacher Xiao Chu's body became more and more terrifying, he quickly sighed to his grandfather: "Grandpa, you are not active in eating, and you have problems with your thoughts."

Professor Zheng was already fascinated, and at this moment, Xiaosha waved his hand: "You eat first, I'll ask Teacher Xiao Chu a few questions."

"A few questions."

Chu He was very unhappy - he was not sincere at all for treating guests to dinner. He had said that she might as well go to the cafeteria to get her own meal!

Professor Zheng was unaware of it: "This infrared detection..."

"I'm hungry, I don't understand what you said."

Professor Zheng:...

How can I not understand this?

He looked over anxiously, but found Xiaoxuan staring at him with a helpless look: "Grandpa, we are treating Teacher Xiao Chu to dinner today."

"Oh oh oh!"

Professor Zheng suddenly came to his senses, then looked at the table, and quickly took out tickets and money from his pocket: "Xiaoxuan, please invite Teacher Xiao Chu to dinner, how can you just make this little meal? Go quickly and send all the food coupons to the cafeteria, and ask the chef to stir-fry a meat dish for us quickly."

As he said that, he smiled at Chu He again: "Teacher Xiao Chu, I feel wronged that you have waited for a while."

Meat dishes?!

That must be more delicious than the fried eggs with minced vermicelli!

She was instantly satisfied: "It's okay, it's okay, you're not afraid of having a good meal - good kid, go and get a meal! As soon as you go to the nursery, I know you are a smart child!"

Xiaoxuan:...

Adults are really bad.

...

Seeing that Teacher Xiao Chu's expression was gone, Professor Zheng breathed a sigh of relief and quickly handed over the bumpy blackboard brick:

"Teacher Xiao Chu, I can't understand these two parts, why don't you tell me?"

Chu He:???

"I can't understand either!"

She said in surprise - according to guess, she is a white and rich beauty who is about to wear. How could she have such an ugly thing?

Professor Zheng was speechless: "You have made it all..."

Chu He was confident: "I knew how they fought when I saw them, but I couldn't tell them. I couldn't understand what you asked me about the truth."

She really can't explain it.

What's the principle?

I can't remember it, anyway, this is the reaction between the two. Isn't this a matter of course?

Design concept?

Don't you do whatever you need?

There are often some messy things in her mind, such as "metamagnetic energy core axis, star core annihilation field, rescue dragonflies, large circles, three circles, and four circles" that appear in her mind, but those are scales and claws, and in addition, they all need to build a network first.

As for the Internet...

Anyway, there is no such thing here now, and there is no chance for computers.

So Chu He never thought - she had thought of rubbing a refrigerator with her hand. Although she had never made it, it should be useful to piece it together. But... even the iron sheet is a key material now, where did she get the materials!

What's more, the wires at home have not been pulled up yet!

What kind of bicycle do you need when you have no electricity?

The energy is here! The lack of supplies is so scarce, it is simply no way out!

...

Professor Zheng asked over and over again, but he found in despair that Chu He really didn't understand the principle.

But thinking about it is, too.

Since the family of Shijiao came here to live, the army must have checked it. If you really have the ability, you will definitely not be able to do this. It is a waste.

What's more, he used to do farm work in a small mountain village, and he was not full or warm in food, so he had no chance to get into this new type of knowledge. Professor Zheng is sure that this technology, even if it is not available abroad, is not available.

So spies are even more excluded.

So the question is, if there is no teacher, it is not a spy. How could a rural child have?

I can't explain the principle clearly, but I can do it based on instinct. This is similar to solving mathematical problems by fortune-telling.

That can only be - born to know!

Oh my God!

This is a genius!
