This end.

Zhong Yuxiu and the old man returned to the laboratory. The old man, Gu Lingguo and Fang Guozhong continued to take care of the children; Zhong Yuxiu continued to take Goudan to do the experiment, and without distraction, she made a preliminary success in three days.

A small defensive home toy, she repeatedly enters her pupils, fingerprints and sounds; two of them can only be opened with one combination, and only the pupils, fingerprints and sounds cannot be opened.

As soon as the results came out, Yan Guofeng also tried it himself; Zhong Yuxiu cleared the data in the toys in his home and let the old man enter his pupils, fingerprints and sounds.

"Yuxiu, that's all?" After the input, the old man looked up and asked.

Zhong Yuxiu nodded, "Yes, grandpa, that's fine; try whether it's the same as what I said."

"Okay."

Yan Guofeng held the home toy and pointed the sensor mouth at his pupil. The home toy sounded a few times, and the light on the toy turned on a red light; it means that it cannot be turned on, so it must be turned on to turn on the green light. He entered his fingerprint again, and the home toy model turned on with a click.

"Hey, it's really OK, Yuxiu, you're so awesome." You can study such good things.

"Grandpa, what I mean by the induction door system is running on this principle. Now the results are coming out; in no time, the induction door will be born." One of her projects is completed and the next project is about to start.

Yan Guofeng returned the toy model of the home to her, "Clear it, I'm not suitable to hold it."

"Okay." It's not suitable for the old man to submit the success yet. This success must be raised with the report, and the above will use this set of things to apply for a patent. After the patent is implemented, another set will be made for the old man to play with.

Yan Guofeng reluctantly withdrew his gaze and turned back to the small room. When the three of them saw Grandpa Zeng coming, they screamed a few times, as if asking him what he was going to do.

Because the operation was facing away from the small room, let alone the children didn't know what they were doing, even Gu Lingguo and Fang Guozhong didn't know what the old man did in the laboratory.

"Grandpa Zeng is going to have fun. Be good, wait until you are done to play for you."

"Play." Li Zhen stretched his head excitedly and looked at the other end of the glass window.

Li Ming reached out to hug him, and Yan Guofeng took the opportunity to hug him, "Everyone is obedient, don't make trouble! Let your mother work hard."

"Zuzu." Li Ji turned his head and looked at him.

Yan Guofeng nodded lightly, his eyes fell on his face, and he smiled, "Grandpa Zeng's good great-grandson."

"Zuzu, mom..." The Book of Rites pointed at the people inside.

"Yes, your mother is working, you must be obedient and not cry; if you are hungry, you will tell Grandpa Zeng, and those who want to pee and poop should also tell Grandpa Zeng."

The key point of the ceremony is: "Yeah, mom."

"Yes, your mother is a good mother, so you should feel sorry for her; be more obedient and sensible, and you cannot add burden to your mother." Yan Guofeng slowly hugged Li Ming and found a place to sit down. Gu Lingguo and Fang Guozhong held two children and followed. Yan Guofeng said to them: "You have added a lot of burden to your mother before, so your mother was worried about you when she was working."

Rite turned his head to look at the laboratory at the other end of the glass window, and my mother and the strange dog ball were inside; they would be good, and my brother couldn't cry.

Yan Guofeng didn't know that his great-grandson had some ideas, probably this is why people with high IQ can remember it at a young age; some people remember things a few months after their birth, and it is hard to say such things.

A day passes like a white horse.

Zhong Yuxiu always feels that she doesn’t have enough time. It would be better if the day was longer; why would it take twenty-four hours instead of forty-eight hours a day?

The report and toy models were taken home, and Gu Lingguo and Fang Guozhong informed Comrade Xi Nian in advance. That night, Xi Nian came to the Yan family courtyard of Hongxing Village. The courtyard was brightly lit, and Xi Nian was introduced into the main hall as soon as he entered the courtyard.

"Hello, Mr. Yan." Hey, first say hello to the old man when he entered the house.

"Okay, Comrade Xi sit down, I'll take the children out for a walk, you guys talk about your affairs." Yan Guofeng picked up a child and stood up and walked out.

Goudan hugged the other two and followed, and only Xi Nian and Zhong Yuxiu were left in the main hall; Xi Nian looked at her, "Yuxiu, congratulations; I heard that you have achieved another result, and your success frequency is really high."

"A model that I just came out today has not been made yet. You can give it to you to apply for a patent for me first, and then, this business will be handed over to my partner to do it." Yuxiu made a straightforward move.

Xi Nian asked: "What kind of good thing is it?"

"Induction door, a defensive door opened with pupils, fingerprints and voice control."

"Defensive?" Xi Nian immediately grasped the key point.

Zhong Yuxiu nodded, "Yes, defensive, once you find something or person that is harmful to the owner of the home, they will turn on the defense system as soon as possible; bad people cannot enter the home, and opening the door requires two comrades to verify. You can have pupils and fingerprints, fingerprints and voice controls, pupils and voice controls; as long as you cooperate with each other, you can open it, and just one item cannot be used."

This is also to prevent thieves from secretly using a feature of their owner’s home to open other people’s homes.

"Not only that, three items can be verified at the same time; this requires the owner's setting, but at least two items." In order to prevent some people from seeking simple and easy things and having a lucky mentality.

Xi Nian probably understood, "Can this kind of research be applied to laboratories or every household?"

"Yes, the point is about these things." Not people.

"I understand. After your partner makes the induction door, all laboratories and research institutes in Beijing must be installed first; first, the Military Industry Research Institute and all confidential places in the army will be used, and the political circles may also find your husband."

Zhong Yuxiu nodded, "I am the first to install it, first of all my laboratory, and then our home; the small buildings in the compound will also be installed with defensive and induction doors. When my installation is completed, you can make an appointment with my husband."

"Can."

There is nothing wrong with the things that Zhong Yuxiu has developed to enjoy first; on the contrary, the things she dares to use are assured that they have a clear idea and confident heart.

Such things are even more mouth-watering.

If a person has developed something and the developer dares not use it, he has to think about it again.

"I have given these things to my husband and will not be authorized to others in a short period of time; I will hand over the patent rights to my husband." Don't look for her if you have any questions.

Xi Nian asked: "What if we need it? Induction door equipment is a good thing to earn foreign exchange."

"You can discuss with my husband what to do, and I will not interfere."

Speaking of this, Xi Nian already understood her plan; such things were insignificant to her, and she had no intention of managing the patent rights, and gave the full rights to Yan Rushan to distribute.
