Chapter 400 Just Give Me Whatever You Like

Yu Chu was simply stunned.

How can a walking aid have so many tricks, but it is very practical? Each one is quite practical, "Hong Fei, how much does it cost?"

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

When Yu Chu heard this, he immediately took out the money in his pocket, which was only a few dozen yuan.

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

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

Qin Hongfei stood up to see her off.

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

In the midst of shock, he suddenly felt a cold feeling behind his back. He couldn't help but turn around. Tang Jinnan was holding his small computer in his hand. He glanced at Qin Hongfei's studio from a distance, and then looked at him again, "Uncle Sun, Yu "Do you know why Chu's grandfather lived to be one hundred and eight years old?"

Sun Shu: "Why?"

Tang Jinnan said, "He doesn't care about other people's business."

Sun Shu; "..."

A warning, definitely a warning.

But is this nothing?

He wanted to ask about Qin Yan's sister, but when he received Tang Jinnan's seemingly gentle but cold look, he swallowed his words. Forget it, he couldn't ask, he didn't dare to offend her.

People like them are easily injured, and when they are injured, they need to rely on the medicine of the old lineage! Especially Tang Jinnan's, I can't afford to offend him.

Ever since Qin Yan's sister's identity was exposed, Qin Hongfei has become much more casual in doing things and no longer hides it. Sun Shu suspected that she just held on to her pigtails and felt that she did not dare to tell anyone. In fact, she did not.

For medicine, I need to rely on Tang Jinnan, and for equipment, I need to rely on the little girl.

He can't afford to offend anyone, he is so humble.

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

Yu Chu hurried over in a hurry, "Grandpa Zeng, Grandpa Zeng... I'll wait a minute. Fortunately, I caught up."

Grandpa Yu Zeng saw 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 turned red!

You laughed at me for running like this. After stamping her foot angrily, she said nonchalantly, "Grandpa Zeng, look, it's a walker."

She threw away the box and took out the walker. It can be retracted and can be pulled open directly. When it fell into Yu Jia's eyes, she couldn't help but laugh, "I have given this to you Grandpa Zeng before..." The words stopped in shock. .

Because Yu Chu had already pressed the third button excitedly, a tripod appeared from under the walker, "This is something you can use, Grandpa Zeng..."

"And this." Press the second button.

Xiao Q's voice sounded.

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

Several members of the Yu family have already stayed.

Aunt Yu Zeng got out of the car in great surprise, "Xiao Chu, do you think your little classmate made this?"

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

This is not only awesome, it's too awesome.

Yu Chong said, "It really knows the way, and it's not just a flowery thing."

Father Yu said, "You'll know after you try it, Xiao Chu, bring it over."

Yu Chu handed it to his father.

Yu's father started to try it out. After pressing the second button and walking to the wall, the little Q lighted up: "There is an obstacle ahead. There is an obstacle ahead. Master, please take a detour."

Father Yu tried again and walked to the corner of the front street. When he was still fifty meters away from the turn, the navigation voice sounded again, "There is a crossroad fifty meters ahead, and the one leading to the left is..."

Aunt Yu Zeng was extremely surprised and said, "It's amazing. It actually has a navigation function. But I don't know what material it is made of, and I don't know if it is reliable. I'd better keep it for now. Don't rely too much. This time I go to the central government. Cheng, I'm thinking of going to Sister Li to buy it to see if there is any similar equipment. I heard that the Tang family is researching..."

Yu Chu pouted.

Mother Yu smiled and touched her head, "Don't blame your great aunt for not trusting her. Your classmate is so young. Of course, being able to make such a thing must be very powerful. There is no doubt about this. Waiting for your grandpa When we come back, we invite her to come and thank her properly.”

Yu Chu said, "It's almost the same, but Grandpa Zeng, please bring it with you. Hongfei finally made it, and it also has a positioning function. Cousin, you have to bring it with you for grandpa."

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

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

But Yu Chong smiled and said, "I knew it." It was 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 coquettishness and took it in his hand, "Okay, take it."

He also liked this thing very much. Time was tight. After grabbing the things, the Yu family set off. After several turns, they went to the big city of Yangcheng. As soon as they landed, someone came to protect the old man and Yu, who were the inheritors of intangible culture. Great aunt, all the way to the hotel.

When he got to the door, the old man's old habit broke out. If he wanted to go by himself, the people around him couldn't stop him, so he could only wait carefully.

Mr. Yu took out the crutches given by his great-granddaughter and used them. Because it was a hotel, the elevated road specially designed for the elderly was very flat. Even if the walker was inferior, someone was keeping it, so Yu Chong didn't care.

Walk all the way to the elevator.

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

Aunt Yu Zeng smiled and said, "It's good to be happy, but after all, the little girl made it, so I don't worry about using it. I'd better ask Sister Li if we can order one of the new products that the Tang family is going to produce..." Li said in her mouth Sister, I am a college classmate.

It is a normal mentality. For people like my great aunt, I want to use brand-name products, not because of luxury and prestige, but because the quality is guaranteed.

There is no conflict between admiring Qin Hongfei and her concern about quality.

The elevator dinged.

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

The moment the sound rang out, an old man who had just walked down from the steps with his hands behind his back sniffed his back. He tried hard not to beat his legs with his hands and lose his dignity. He paused in his steps, looked this way, and then his eyes were on the way. I paused for a moment and heard something making a sound. Is it this?

navigation?

When the elevator door opened and Little Q's voice sounded again, the old man was completely sure. He looked at the walker curiously and said with great interest: "Wait a minute..."

The Yu family members turned their heads. Among them, Aunt Yu Zeng was extremely surprised and her expression became solemn: "Mr. Li."
