Yu Zhen was simply dumbfounded.

How can there be so many tricks for a walker, but it is very practical, and everything is quite practical, "Hongfei, how much is this." ”

Qin Hongshou tilted her head slightly, "You can look at it and give it casually, this is in the trial stage, just so that your great-grandfather can help me use the experience and give me back." ”

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

Qin Hongshou didn't care either, and accepted it very casually, "If you have any questions, you can find me." ”

Yu Zhen said happily, "Thank you Hongscarlet, then I'll go back first." ”

Qin Hongshou got up to see her off.

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

was shocked, suddenly felt a cold behind him, he couldn't help but turn around, Tang Jinnan held his small computer in his hand, glanced at Qin Hongshuang's studio from a distance, and then looked at him again, "Uncle Sun, Yu Zhen's grandfather can live to be one hundred and eight years old, do you know why?" ”

Sun Shu: "Why? ”

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

SUN Shu; “……”

Warning, absolutely warning.

But is this a nossy thing?

This Qin Yan's sister, he wanted to ask, but when he received Tang Jinnan's seemingly gentle and really cold gaze, he swallowed the words back, forget it, he can't ask, he doesn't dare to offend.

They are easily injured, and when they are injured, they need to rely on the medicine of the old vein! Especially Tang Jinnan's, he can't be provoked.

Since Qin Yan's sister's identity was exposed, Qin Hongshou has done things a lot more casually, and she no longer hides it, Sun Shu suspects that she just grabbed her pigtail, and felt that she didn't dare to say it, but in fact, it was.

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

He can't afford to offend anyone, and he's humble.

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

Yu Zhen hurried over, "Great-grandfather, great-grandfather...... Wait, I'm glad I caught up. ”

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

Yu Zhen was so angry that his face turned red!

I laughed at you for running like this, and after stomping her foot in anger, she said indifferently, "Great-grandfather, look, walker." ”

She threw away the box and took out the walker, which can be retracted, which will be directly opened, and it will fall into the eyes of the family, and she can't help laughing, "I have already given your great-grandfather ...... before this" The voice was stunned.

Because Yu Zhen had already pressed the third button excitedly, a tripod came out of the brush under the walker, "This can allow great-grandpa you to borrow..."

"And this." The second button goes down.

Little Q's voice rang out.

"This is navigation, it has a map of the world, Hongfei said, it will be updated according to the main system satellite to update it synchronously, don't worry about the old map, grandpa if you don't know the road, you can ask it."

Several members of the Yu family have already stayed.

Aunt Yu got out of the car in surprise, "Xiaozhen, you said, this was done by your little classmate?" ”

Yu Zhen nodded violently, "That's right." She's amazing. ”

This is not too powerful, is it too powerful.

Yu Chong said, "It really knows the road, don't be a showman." ”

Yu's father said, "Just try it, Xiao Zhen, take it." ”

Yu Zhen handed it to his father.

Yu's father started to try, the second button went down, and he walked to the wall, and Xiao Q lit up; "There is an obstacle ahead, there is an obstacle ahead, please take a detour, master."

Yu's father tried again, walked to the place where the front street turned, and when he was still fifty meters away from the turn, the navigation voice sounded again, "There is an intersection fifty meters ahead, and the one leading to the left is..."

Aunt Yu Zeng's grandmother was pleasantly surprised and said, "It's amazing, it can really have a navigation function, but I don't know what material it is made of, and I don't know if it's reliable, so let's keep it first, I can't rely too much, this time I went to Yangcheng, I thought about going to Sister Li to buy it to see if there was any similar equipment, I heard that the Tang family is researching..."

Yu Zhen pursed his lips.

Yu's mother smiled and touched her head, "Don't blame your great-aunt and grandmother for not trusting it, your little classmate is so young, of course, it must be very powerful to make such a thing, there is no doubt about this, when your great-grandfather comes back, we will invite her to thank her well." ”

Yu Zhen said, "It's pretty much the same, but great-grandfather, you can also bring it, Hongscarlet is not easy to do, and there is also a positioning function, cousin, you have to bring it to grandpa." ”

Yu Chong snorted, not very optimistic about Qin Hongshuang's things, "Did she take your money?" ”

Yu Zhen knew what he meant, and said, "I gave it myself, it's just a few dozen yuan." She felt that there were more than dozens of things.

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

Yu Zhen didn't like to talk to him anymore, and looked at his great-grandfather.

Grandpa Yu couldn't resist her coquettishness, and held it in his hand, "Okay, take it." ”

He also likes this thing very much, the time is very tight, take the things, the Yu family set off, after several turnovers to the big city of Yangcheng, as soon as it landed, there were special people to protect the old man and Aunt Yu as the inheritor of intangible culture, all the way to the hotel.

When he arrived at the door, the old man's old mistake was committed, and he wanted to go by himself, but the people around him couldn't stop him, so he could only wait carefully.

Old man Yu took out the crutches given by his great-granddaughter to make an envoy, because it was a hotel, and the road specially raised for the old man was very flat, even if the walker was a defective product, but someone kept it, and Yu Chong didn't care.

Go all the way to the top of the elevator.

Grandpa Yu couldn't help but say, "This crutch is very light, so it's easy to use, you have to thank others when you go back, you can also buy one and use it." ”

Aunt Yu said with a smile, "It's good, but after all, the little girl made it, and I don't have to worry about it, so I still ask Sister Li if I can order a new product to be produced by the Tang family..."

It's a normal mentality, for people like Aunt Yu, things need to be branded, not because of luxury and face, but because the quality is guaranteed.

Appreciating Qin Hongfei and her worries about the quality are not contradictory.

The elevator clanged.

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

The moment the voice sounded, an old man who had just walked down from the step question sniffed his back, tried not to let his hand beat his legs, lose his share, paused, looked this way, and then looked at the walker, what is the sound of something, is this thing?

Navigation?

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

The Yu family turned their heads, and among them, Aunt Yu's great-aunt was surprised, and her expression was solemn: "Old Li." ”
