"Is this a navigation system?" Li Lao's eyes fell on the walker, which involved a wide range of calculations, and the navigation chip was one of them.

"Teacher, this walker seems to be a design sent by the Tang family, did you buy it from the Tang family?" The girl behind Li Lao spoke.

Hearing the Tang family, Yu Chong involuntarily tensed his back, and before Aunt Yu opened her mouth, she hurriedly said, "Yes, I bought it at the Tang family." ”

Great-grandfather Yu is old and can't hear words.

Aunt Yu looked at this junior in surprise, and she didn't know why he was panicking.

Only then did Li Lao set his eyes on them, familiar with them, but they didn't know them.

The female student introduced, "Teacher, these are the two masters of the intangible inheritance of traditional musical instruments, Master Yu. ”

Li Lao's eyes suddenly warmed, and his tone was kind: "I have heard that Yu Lao has a set of ancient chimes that have been well preserved." "There is a national treasure in the traditional musical instrument industry who is one hundred and eight years old, and he is talking about the old man in front of him, who is dozens of years older than himself.

Yu Chong was a little happy and cautious: "I didn't expect you to know this, Old Li." ”

Grandpa Yu reacted a few beats slower, and after knowing Li Lao's words, he couldn't help but say seriously, "I have also heard that the automatic electronic technology developed by Li Laoxin has greatly promoted the efficiency of my country's business and economy. ”

A ragged colt may make a good horse.

For people like Great-Grandpa Yu, there is nothing more joyful than seeing Huaxia progressing, and he pointed to Great-Aunt Yu, "If Elder Li is free, you can come and listen to my sister's concert." ”

Li Lao nodded, "If you are free." ”

After greeting for a while, the two parted and went to the hotel floor where they were staying.

Aunt Yu suddenly spoke, "Xiao Chong, why did you lie just now?" ”

Yu Chong said confidently, "Grandma, haven't you heard, this walker is very similar to the Tang family... Perhaps, it was Qin Hongfei who saw the Tang family's walker plagiarized somewhere, and I was for my cousin's good. ”

Aunt Yu was also puzzled for a while, "Maybe it's just that Old Li's people have lost their eyes." "Walkers, actually, they're all pretty much the same.

Yu Chong said speechlessly, "Anyway, just in case." ”

The old man didn't hear the dispute between the two, but he wanted to go out for a walk.

The other side......

Li Lao took his students back to his residence in Yangcheng, and the student assistant happened to be holding the teapot for making tea and said, "Teacher, Teacher Tan is here to visit." ”

The two scientific researchers of the Tang family, one in his early thirties and one in his fifties, the latter has gray hair, and he is also quite famous in the scientific research community, but at this moment, in front of Li Lao, he still has to be polite, respectful, and his tone is also a little hurried: "Li Lao, you came to disturb you today to ask you to see something." ”

Li Lao: "Sit." ”

The two of them sat down again, and without ink, they took out something directly.

Tiny chips! It's not big, it's almost the size of an MP3, Li Lao was a little puzzled, "This..."

The man surnamed Tan couldn't wait to take it out, "This is a navigation chip, which has a map of twenty-four cities in China, which is the most critical thing for the walker that Tang wants to promote this time, but when I tested it, I found that there was something in the circuit of this chip that I couldn't understand, and I didn't know what it was." ”

Down's is cautious, quite cautious.

The man surnamed Tan lifted his glasses, he was afraid that it was an anti-prison device or something.

Li Lao Xing, listening to him say seven, seven, eight, eight, and eight, he knew in his heart, "The main system." ”

The man surnamed Tan was puzzled, "The main system? ”

Li Lao nodded and stretched out his hand, the man immediately handed him the chip clearly, Li Lao raised his hand, and the female assistant immediately took his computer clearly.

Li Lao was not slow to tap on the computer, and finally came out with a distribution map, and the two people on the opposite side immediately subconsciously raised their butts and approached the screen to see, "The main system is used to supervise the subsystem, and at the same time, it is convenient for the people who master the main system to update the data at the same time." ”

As he spoke, he plugged the chip into a converter and connected it to the computer, and after entering the page, he paused, "You should be a subsystem..."

The man with the surname Tan has made achievements in scientific research, especially in the field of medicine.

Can these ......

He smiled awkwardly.

Li Lao sighed, "Didn't you say that there are only twenty-four city maps, because the main system is not perfect, and the maps of other large and small cities will have to be loaded into it later..."

Late planted in the map, late in the game.

"Do you have a sample of this walker?"

"Yes, yes, I just brought it over and wanted you to help you study it and see how the market is." The man surnamed Tan is also very famous in the electronic area, but he is very respectful to Li Lao, he didn't know how to propose it to Li Lao just now, after all, according to the market, this thing is for people of Li Lao's age, but it is a little offensive to say this, I didn't expect him to bring it up himself, it's really good.

Qin Hongshuang, the template of the walker, had already sent a picture through the Internet, and Tang's side made about ten samples.

The chip only arrived today, this thing looks simple, but it will be difficult for him to produce it in large quantities, so Baba came to Li Lao for advice.

After bringing the walker in, Li Lao looked at it and asked, "You Tang Clan have already taken out the food?" "It's the same as the walker he saw at the hotel.

The man surnamed Tan shook his head and said, "No, how can it be that the chip has just arrived today." ”

Li Lao said quietly, "Today I was in the hotel and saw the old gentleman of the Yu family using this walker. ”

The man surnamed Tan said, "Oh, that's probably the person Miss Zhou Yun'er happened to know from the Yu family, right?" ”

Li Lao nodded, no longer asked, there is actually no difference between the walker and the ordinary ambulator, but there are three buttons, and there is a small hole embedded in the chip, Li Lao tried to connect the chip in, this is not just put in, it also needs to be connected to the electrical route, after it is done, it can be regarded as perfect, he tried to distinguish the next three buttons, and when the sound of navigation sounded, his face couldn't help but be stunned, and asked, "You say...... This walker was made by Zhou Yuner? ”

Zhou Yun'er knew that Ms. Tang had been secretly sponsoring college students for a long time, and these college students would work for the Tang family when they reached their age.

Zhou Yuner is one of them, who has made achievements in medical machinery in the early years, and the gap between medical machinery and electronic machinery is not large, but it can be regarded as a span, which is very powerful.

First the monitor, then the walker.

These are all related to chips, and he couldn't help but think of the computers that he dismantled, "Has Zhou Yun'er ever made a computer?" ”
