Yu's father said, "It was with the help of Xiaochu's classmate that we found it."

"This walker helped us a lot this time. Fortunately, Xiaochu insisted that your grandfather Zeng take it."

"Come to think of it, this thing is so powerful, and Xiaochu only gave him a few dozen yuan." Yu's father was a little embarrassed. "

Location device, how is it possible, it must be a coincidence." Yu Chong found it hard to believe. "

How can it be a coincidence? The little girl of the Qin family lives in Qinhuai Street and has never been to Yangcheng. If she didn't really have this thing, how could she know the map of Yangcheng?" Yu's father believed in Qin Hongfei, although she was young.

But there are many people who can do great things at a young age, and there are many geniuses in the music industry.

The ten-year-old genius played the eighth-grade piece "Bells" in the provincial competition, which shocked many people.

Yu's father felt that this was possible, and nothing else was impossible, not to mention that he helped was a fact.

Seeing his nephew in a state of despair, he shook his head, "You've worked hard this time, too. By the way, Qin Hongpin doesn't seem to want people to know what she did. If anyone asks, don't mention it, and always say you don't know, understand?"

Yu Chong nodded uncomfortably, "Okay."

In the evening, in order to express their gratitude, the Yu family went door to door to visit and give gifts to those who helped the old man. When

it came to Mr. Li's place, Yu's father didn't dare to come in person, because his great-aunt brought Yu Chong to deliver it.

Here at the Li family.

The female assistant was talking about the walker she had seen, which was exactly the same as the one sent by the Tang family. As she was talking, Aunt Yu Zeng came to the door. The two elders talked about their own things, and the female assistant was responsible for entertaining Yu Chong. She asked, "Mr. Yu Chong, excuse me, do your cousin know Zhou Yun'er?"

Yu Chong knew that the other party was a master's and doctoral student in Central City, and was highly regarded by the tutor and recommended. Ordinary people can't help but have some respect for the top students, so he answered seriously, "Who is Zhou Yun'er? I don't know her."

The female assistant explained, "Mr. Yu's walker was made by Zhou Yun'er, she is from the Tang family."

Yu Chong had heard her mention this more than once, "Are you sure that the walker that my grandfather Zeng took was from the Tang family?"

The female assistant nodded affirmatively.

Yu Chong was a little contemptuous.

So it was Qin Hongfei who plagiarized the Tang family's stuff. At the age of fifteen, she made a locator. The uncle was too proud of her and thanked her for finding Grandpa Zeng.

He hated the thief who stole the finished product, especially now that the Yu family was very grateful to Qin Hongfei and no one knew her true identity. "That didn't come from the Tang family. It was made by a classmate of my cousin."

The female assistant concealed her surprise and said, "I wonder if your cousin's classmate is called..."

Yu Chong replied, "Qin Hongfei."

Qin Hongfei!

Is it the child that the teacher is checking?

The female assistant blinked her eyes. The aunt and nephew of the Yu family left. She thought about it and told Mr. Li.

The chip that Mr. Li was looking at fell to the ground with a click.

The female assistant was startled, "Teacher."

Mr. Li was silent for a while and took a deep breath.

"Tang Yue, that bastard!"

"Qin Yan, that little bastard."

"Jin Nan..." Forget it, he can't curse.

Mr. Li didn't go up to pick up the chip. He stood up and paced back and forth. He was not a fool! After Qin Hongfei's clues came out bit by bit, he pieced together a lot of things and had an idea in his mind. He was not sure before, but now he was 70% sure that the computer was 80% made by this kid.

Go tie up Jiang Wan and scare him and see?

No...

He forced himself to calm down. He was a mature old man and he couldn't do such a childish thing.

You want to hide your identity, right? I'm going to break it and make you convinced.

The female assistant picked up the chip and was worried. She always felt that the teacher seemed crazy. What should she do?

Mr. Li calmed down, feeling angry and excited: "Qingyun, have the people sent to Qinhuai Street set out?"

The female assistant looked at her senior brother subconsciously.

The man adjusted his glasses and said, "Not yet, I want to wait until the seminar is over..."

Mr. Li frowned, "Notify everyone and let him come back as soon as possible, and then go to Qinhuai Street to secretly protect Qin Hongpi."

At this moment, his two students were stunned.

The other person was someone who Mr. Li personally cultivated from childhood to adulthood.

Such a person would waste time protecting Qin Hongpi.

The man hesitated, "Teacher, is this..."

Master Li saw through his thoughts, stopped talking, and indicated that he would do it. After thinking for a while, he said, "Just keep an eye on her and protect her. Don't let anything happen to her, and don't let her find out, otherwise you and your brother won't have to come back."

Qin Huai Street.

Qin Hongfei didn't know that someone was rushing here from Central City for her, because the Tang family also responded to the disappearance of Master Yu Zeng.

The person who was in contact with her sent a message, "Ms. Qin, Boss Tan said that he saw an old man using the same walker at the seminar."

Qin Hongfei replied, "I gave it to him."

The other party thought about it and said, "Boss Tan said that he heard that Mr. Yu was found by relying on a locator?"

Qin Hongfei knew what she wanted to ask, and said directly, "The main system is already being worked on."

"Is there really a main system???"

"Yes."

Just one simple word.

Qin Hongfei looked at the main system. This was a bit troublesome. It could not be transmitted online. It had to be taught step by step. After a moment of hesitation, she typed the page and the code flow over. "This, can your technology make it yourself?"

The main system is the main page that manages all chips. The chips are divided into AB versions. Walkers will be produced with numbers, and the purchaser can request whether the positioning function is needed according to the needs. If necessary, the customer's user information can be entered into the main system. Once there is a need, the number can be directly entered for positioning.

After accepting the transmission of things, the Tang family's research institute has already been turned upside down.

The man surnamed Tan hurriedly called the most senior IT staff in the institute, the programmers of the chip production line, and himself to go online and look at the input sent by the main system. This system has more data than the previous ones. It

even broke down halfway through the transmission, and it was transmitted in three times.

"Please ask Miss Qin to wait for a while, we will study it."

"Okay."

Two hours later.

The IT staff sitting in front of the computer shook his head, "NO, Boss Tan, I can't do it, it's too complicated, let the child go." These are all areas of knowledge he has not been involved in.

"To build this main system, I'm afraid this person needs to come and create it personally."

Tan Zuo guessed that this was also the case.

Qin Hongfei needs to come in person. He asked the staff to move aside, sat down at the computer, and typed: "Ms. Qin, the main system creation failed, you may need to come in person. Let me talk to the boss about the round-trip air tickets. Or do you have any needs?..."
