Back to 90s she made a fortune from scientific research

Chapter 400: You Can Give It Anywhere

Yu Chu was dumbfounded.

A walking aid has so many tricks, but it is very practical, each of which is quite practical, "Hong Fei, how much is it?"

Qin Hongfei tilted her head slightly, "You can give me whatever you want. This is in the trial stage, and it's just for your grandpa Zeng to help me use the experience and give me feedback."

As soon as Yu Chu heard this, he immediately took out the money in his pocket, only a few dozen yuan.

Qin Hongfei didn't care, and accepted it casually, "If you have any questions, you can contact me."

Yu Chu said happily, "Thank you Hong Fei, then I'll go back first."

Qin Hongfei got up to see her off.

Sun Shu, who accidentally passed by, was a little stunned. What did he see just now? "Navigation? Is there such a thing in Yangcheng?" If not, how could Qin Hongfei master such advanced technology?

Just as he was in shock, he suddenly felt a chill behind him, and he couldn't help turning his head. Holding his small computer in his hand, Tang Jinnan glanced at Qin Hongfei's studio from a distance, and then at him again, "Uncle Sun, so Chu's grandfather lived to be one hundred and eight years old, do you know why?"

Sun Shu: "Why?"

Tang Jinnan, "He doesn't care about other things."

Sun Shu; "..."

Warning, definitely warning.

But is this really a nostalgia?

He wanted to ask about Qin Yan's sister, but when he received Tang Jinnan's seemingly gentle but indifferent gaze, he swallowed the words back, forget it, he can't ask, and dare not offend.

People like them are easily injured, and once they are injured, they need to rely on the medicine of old age!Especially Tang Jinnan's, he couldn't be offended.

Since the identity of Qin Yan's younger sister was exposed, Qin Hongfei has become more casual in her actions and no longer hides her secrets. Sun Shu suspects that she just took hold of her pigtails and felt that she dared not speak out, but in fact she did.

The medicine depends on Tang Jinnan, and the equipment depends on the little girl.

He can't afford to offend anyone, how humble.

The Yu family is preparing to leave for Yangcheng, and the cars are all ready.

Yu Chu rushed over in a hurry, "Grandpa Zeng, Grandpa Zeng... wait a minute, luckily I caught up."

Grandpa Yu Zeng watched the little girl running out of breath, pointed at her, and said with a smile, "Look, it's really useless."

Yu Chu was so angry that his face flushed!

You still laughed at me for running like this for you. After stomping her feet angrily, she said carelessly, "Grandpa Zeng, look, a walker."

She lost the box and took out the walker, which can be retracted. After being pulled open, it fell into the eyes of the family, and she couldn't help laughing, "I gave you this before..." The voice stopped in shock .

Because Yu Chu had already excitedly pressed the third button, a tripod popped out from under the walker, "This is for Grandpa Zeng to borrow your strength from..."

"And this." The second button went down.

Little Q's voice sounded.

"This is navigation. It has maps of the whole world. Hong Fei said that it will be updated according to the satellites of the main system so that it will be updated synchronously. Don't worry about the old maps included. Grandpa, if you don't know the way, you can ask it."

The members of the Yu family have already stayed.

Aunt Yu Zeng got out of the car in amazement, "Xiao Chu, tell me, your little classmate made this?"

Yu Chu nodded sharply, "Yes. She is very powerful."

This is more than powerful, it is too powerful.

Yu Chong said, "It really knows the way, don't put on airs."

Father Yu said, "Try it and you will know, Xiao Chu, bring it here."

Yu Chu handed it to his father.

Father Yu started to try it out. He pushed down the second button, and when he reached the wall, the little Q lit up; "There are obstacles ahead, there are obstacles ahead, master, please detour."

Father Yu tried again, walked to the corner of Qianjie Street, and when there was still 50 meters away from the corner, the navigation voice sounded again, "There is an intersection 50 meters ahead, and the one leading to the left is..."

Aunt Yu Zeng was very pleasantly surprised and said, "It's amazing, it really has a navigation function, but I don't know what material it is made of, and I don't know if it is reliable, so let's put it away first, and don't rely too much on it. City, I want to go to Sister Li to buy to see if there is any similar equipment, I heard that the Tang family is researching..."

Yu Chu pouted.

Yu's mother smiled and touched her head, "Don't blame your great-aunt Zeng for not trusting her. Your little classmate is so young. Of course, it must be very good to be able to make such a thing. There is no doubt about it. Waiting for your great-grandfather Zeng When we come back, we will ask her to come and thank her well."

Yu Chu said, "It's pretty much the same, but Grandpa Zeng, you should take it with you too. Hong Fei finally made it, and it has a positioning function. Cousin, you have to bring it to Grandpa."

Yu Chong snorted, not very optimistic about Qin Hongfei's things, "Did she charge you money?"

Yu Chu knew what he meant, and said, "I gave it myself, only a few dozen yuan." She thought it was more than a few dozen yuan.

But Yu Chong smiled, "I knew it." It's just a gadget to cheat money.

Yu Chu didn't like talking to him anymore, and looked at Grandpa Zeng.

Grandpa Yu Zeng couldn't resist her acting coquettishly, and held it in his hand, "Okay, hold it."

He also likes this thing quite a bit. Time is very tight. After getting the things, Yu's family set off. Aunt Zeng, all the way to the hotel.

When he arrived at the door, the old man committed an old habit. If he wanted to go by himself, the people around him couldn't stop him, so he had to wait carefully.

Old man Yu took out the crutches given by his great-granddaughter to use. Because it was a hotel, the road specially raised for the old man was very flat. Even if the walker was a defective product, someone would keep it, so Yu Chong didn't care.

Go all the way to the elevator.

Grandpa Yu Zeng couldn't help but said, "This crutch is very light, and it's easy to use. Thank you when you go back. You can also buy one and use it."

Aunt Yu Zeng said with a smile, "That's all right, but after all, the little girl made it, so don't worry about it. I'd better ask Sister Li to see if we can order one of the new products that are going to be produced by the Tang family..." The Li in her mouth Sister is a college classmate.

It's a normal state of mind. For people like Grandma Zeng, brand-name goods are used, not because of extravagance and face, but because of guaranteed quality.

Appreciate Qin Hongfei and her concern about quality conflicts are not contradictory.

The elevator dinged.

The walker also sounded, "The door of the elevator ahead will open, please take three steps back carefully, keep a distance and don't pinch your hands."

The moment the sound sounded, an old man who had just walked down from Buti with his hands behind his back sniffed his back, tried not to let his hands beat his legs, lost his position, paused in his steps, looked this way, and then his eyes were helping him walk He paused on the instrument, something made a sound, this thing?

navigation?

When the elevator door opened and Xiao Q's voice sounded again, the old man was completely sure, and looked at the walker with great curiosity, very interested: "Wait a minute..."

The Yu family turned their heads, and among them, Aunt Yu Zeng was extremely surprised, with a solemn expression: "Old Li."
