Yu Chu was simply stunned.
How can a walker have so many features? But it is very practical, and each one is quite useful. "Hong Fei, how much is this?"
Qin Hongfei tilted her head slightly, "Give me whatever you think is appropriate. This is in the trial stage, so I can let your great-grandfather help me use it to experience it and give me feedback."
When Yu Chu heard this, he immediately took out the money from his pocket, just 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 passed by accidentally, was a little stunned. What did he just see? "Navigation? Does Yangcheng have this thing?" If not, how could Qin Hongfei master such advanced technology?
He was shocked when he suddenly felt a chill on his back. He turned around. Tang Jinnan was holding his small computer. He glanced at Qin Hongfei's studio from a distance and then looked at him. "Uncle Sun, do you know why Yu Chu's grandfather could live to be 108 years old?"
Sun Shu: “Why?”
...
...
Tang Jinnan, "He doesn't mind his own business."
Sun Shu; "..."
Warning, definitely a warning.
But is this just a trivial matter?
He wanted to ask about Qin Yan's sister, but when he saw Tang Jinnan's seemingly gentle but actually cold gaze, he swallowed his words back. Forget it, he couldn't ask. He didn't dare to offend her.
They are easily injured, and once injured, they need to rely on the medicine of Cang Lao's lineage! Especially Tang Jinnan's, you can't afford to offend him.
Ever since Qin Yan's sister's identity was exposed, Qin Hongfei has acted more casually and no longer tried to hide it. Sun Shu suspected that she was holding onto his secret and felt that she dared not tell anyone, and in fact, that was not the case.
I have to rely on Tang Jinnan for medicine, and I have to rely on the little girl for equipment.
He can't afford to offend anyone, he's so humble.
The Yu family is preparing to set off for Yangcheng, and the car is ready.
Yu Chu hurried over, "Great Grandpa, Great Grandpa... Wait a minute, luckily we made it in time."
Grandpa Yu Zeng looked at the little girl running out of breath, pointed at her and said with a smile, "See, you are really useless."
Yu Chu was so angry that his face turned red!
I ran like this for you and you still laughed at me. After stamping my feet in anger, she said nonchalantly, "Grandpa Zeng, look, a walker."
She threw the box away and took out the walker, which was retractable. After she pulled it open, Yu Jia saw it and couldn't help laughing. "I have already given this to your great-grandfather..." She stopped talking in shock.
Because Yu Chu had already excitedly pressed the third button, a tripod suddenly appeared under the walker, "This can give you leverage..."
"And this." Press the second button.
Xiao Q's voice rang out.
"This is a navigation system. It has maps of the entire world. Hong Fei said that it will be updated synchronously based on the main system satellite. Don't worry about the included maps being outdated. Grandpa, if you don't know the way, you can ask it."
The Yu family members were stunned.
Aunt Yu Zeng got out of the car in astonishment, "Xiao Chu, did you say that your classmate made this?"
Yu Chu nodded vigorously, "Yes. She is very powerful."
This is more than amazing, it’s too amazing.
Yu Chong said, "It really knows the way, it's not just a showpiece."
Father Yu said, "You'll know after trying it. Xiaochu, give it to me."
Yu Chu handed it to his father.
Yu's father began to try it out. He pressed the second button and walked to the wall. The small Q lighted up, "There is an obstacle ahead. There is an obstacle ahead. Please take a detour."
Yu's father tried again. When he reached the turning point of the front street, fifty meters away from the turning point, the navigation voice sounded again, "There is a crossroads fifty meters ahead. The one to the left is..."
Aunt Yu Zeng said in great surprise, "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 and don't rely on it too much. This time when I go to Yangcheng, I want to ask Sister Li to buy it to see if there is any similar equipment. I heard that the Tang family is researching..."
Yu Chu pouted.
Yu's mother smiled and patted her head. "Don't blame your great-aunt for not trusting her. Your little classmate is so young. Of course, she must be amazing to be able to make something like this. There is no doubt about that. When your great-grandfather comes back, we will invite her to come and thank her."
Yu Chu said, "This is more like it, but you should also take it with you, Great Grandpa. Hong Fei worked hard to make it, and it has a positioning function. Cousin, you have to take it with you for Grandpa."
Yu Chong snorted, not very optimistic about Qin Hongfei's things, "Did she take your money?"
Yu Chu knew what he meant and said, "I gave it myself, just a few dozen yuan." She felt that this thing was worth more than a few dozen yuan.
But Yu Chong smiled and said, "I knew it." It's just a little trick to cheat people out of money.
Yu Chu didn't want to talk to him anymore and looked at his great-grandfather.
Grandpa Yu Zeng couldn't resist her coquetry and took it in his hand, "Okay, take it."
He also liked this thing very much. Time was very tight, so after taking the things, the Yu family set off. After several transfers, they arrived at the big city of Yangcheng. As soon as they landed, special people came to protect the old man and great-aunt Yu, who were the inheritors of intangible cultural heritage, and took them all the way to the hotel.
When he reached the door, the old man's old illness recurred and he wanted to walk by himself. The people around him couldn't stop him and could only serve him carefully.
Old man Yu took out the walking stick given by his great-granddaughter and used it. Because it was a hotel, the road was raised and flat for the elderly. Even if the walker was of inferior quality, Yu Chong didn't care because someone was protecting it.
Walk all the way to the elevator.
Grandpa Yu Zeng couldn't help but say, "This walking stick is very light and easy to use. You must thank the owner when you go back. You can also buy one to use."
Aunt Yu Zeng smiled and said, "It's good, but after all, it was made by a young girl, so I'm not sure about using it. I'd better ask Sister Li if I can order one of the new products that the Tang family is going to produce..." The Sister Li she mentioned was her college classmate.
It's a very normal mentality. For people like Aunt Yu Zeng, they use branded products not because they are luxurious or prestigious, but because the quality is guaranteed.
There is no contradiction between admiring Qin Hongfei and her concerns about quality.
The elevator dinged.
The walker also started to speak, "The elevator door ahead will open soon. Please be careful and take three steps back. Keep your distance and don't get your hands caught."
The moment the sound rang out, an old man who had just walked down the walker with his hands behind his back smelled his back, trying hard not to hit his legs with his hands, which was embarrassing. He paused, looked over here, and then his eyes paused on the walker. What made the sound? Was it this thing?
navigation?
When the elevator door opened and Little Q's voice sounded again, the old man was completely certain. He looked at the walker with great curiosity and was very interested: "Wait a minute..."
The Yu family members turned their heads, and among them, Great-aunt Yu was extremely surprised and her expression suddenly became serious: "Mr. Li."
Back to the 1990s, she became rich through scientific research
