"I thought you would scold me for being a profiteer." Qin Hongfei said with some surprise.

"As long as it's useful, it's worth it no matter how expensive it is. My godfather said that you were able to escape from the Qin City case, and you made the greatest contribution." Although Jiang Yier didn't really believe this, she had seen Qin Hongfei use these weird things in Banxin Island with her own eyes.

If it weren't for these weird things, they might have died in Banxin Island at that time, so they are useful.

Qin Hongfei smiled: "That's right, but it's a pity that you have become smart. I was waiting for you to scold me so that I could raise the price. Now I feel embarrassed to raise the price."

Jiang Yier: "..."

I never thought that you really don't want to do anything related to others.

Qin Hongfei sold two sets to Jiang Yier and received 80,000 yuan. As soon as the money arrived, she immediately went back and wrote a list of materials and handed it to Yu Chi, asking him and Jiang Wan to go to Qin City to buy them. Yu Chi

subconsciously looked at the list of materials.

Qin Hongfei said, "These materials are relatively fragmented and special, and Tang Qihe's material warehouse can't get a complete set."

She had already asked in advance.

Jiang Wan looked at some of the materials, all of which were relatively unpopular. "What are you going to do with this?"

Qin Hongfei said with bright eyes, "To make sensors..."

Jiang Wan and Yu Chi went to Qin City to search for materials. These materials were hard to find on the market, and some needed to go through a complicated processing procedure, so they could only be bought on the black market. However, they were lucky. They had a supply when they arrived, and agreed on a transaction time and place. As a result, the seller went back on his word the next day and refused to sell.

This kind of thing is common in business.

Jiang Wan didn't care, and continued to run with Yu Chi, but they couldn't buy the materials they wanted in the whole market afterwards.

Yu Chi said, "Something is wrong."

Jiang Wan nodded, "It's indeed wrong."

If it was too rare materials, it would be fine, but these are not so rare. Jiang Wan simply went to ask his senior brother Hou Yu for help. Hou Yu was drinking tea in the store. When he saw Jiang Wan coming, his expression changed slightly and the tea in his hand spitted heavily. He quickly squeezed out a smile, "Junior brother, long time no see. I heard that you went to Central City to develop."

Jiang Wan said, "Senior brother, after the greetings, I asked you to take a look at my list of materials..."

After he handed it out, he found that it was wrong.

He handed it out by mistake. Hou Yu took it, glanced at it casually, and said, "Well, these materials you want are not here."

Jiang Wan: "..."

He said strangely, "Senior brother, I just gave it to the wrong one. This one is the real one."

Hou Yu: "…………"

A few minutes later.

Yu Chi and Jiang Wan both frowned, "You mean, someone told us not to sell the materials to us?"

Hou Yu nodded helplessly.

Jiang Wan asked, "Who?"

He didn't remember who he had a grudge against, the only thing he had was: "My teacher? No, my teacher doesn't have that much power. If he had that much power, he wouldn't be so humble as to steal students' works..."

Yu Chi said, "The black market itself is a black market. He can make people there afraid and obedient. He must be from a prominent family..."

Hou Yu glanced at Yu Chi, asked the younger brother in the store to guard the door, and then said, "He is indeed from a prominent family. Unless you have a higher background than him, you can't get this material."

Jiang Wan frowned, "Who is it?"

Hou Yu said, "The Nan family."

Nan family?

Qin Hongfei wondered about the Nan family's origins, but couldn't remember. Yu Chi did ask around. The local wealthy businessmen in Qin City were involved in both the black and white worlds, and the Nan family had some connections with the Shao family.

"Shao Dafu's wife's maiden family is the Nan family, which is in the tax business. You know that if the superiors give you a hard time in this field, it will be difficult for you to deal with it, so generally no one is willing to offend them."

Qin Hongfei turned her head in confusion, "Did I dig up his ancestral tomb?"

Just buying a few materials, and they stopped me from doing so?

Meng Yu: "..."

She thought about it, but she didn't dig.

The Nan family tried hard to block the way. Qin Hongfei wanted to find Feng Guosheng, but the good guy was away on a business trip.

She could only find Qin Yan to find a solution.

Qin Yan watched his sister through the video, listened to the materials she said, and said directly, "These are beyond my scope of involvement."

Qin Hongfei sighed when he saw that he could not help.

Brother or something, it's really useless.

Qin Yan: "..."

When you used me as a mobile sedan in Qin City, you didn't see you dislike it, "You go ask Jinnan, he should have a way..."

Qin Hongfei said, "I have already asked the Tang family."

Qin Yan said, "Stupid, I'm talking about Jinnan, the Tang family is the Tang family, Jinnan may have other ways."

Really?

Okay.

Qin Hongfei immediately turned around and contacted Tang Xiaojin: "Do you have a solution?"

Tang Jinnan asked directly, "When do you want it?"

Qin Hongfei said, "The sooner the better."

Tang Jinnan nodded slightly, "Okay."

Qin Hongfei was surprised to see that he really had a solution. You really have a solution, that's great, better than Qin Yan's.

The leader reached out and picked up the paper to look at it. "These materials are not so rare, right?"

Qin Hongfei said, "Yes, but someone doesn't allow you to buy them. Do you know the Nan family?"

Tang Jinnan's handsome face showed some confusion: "Nan family... Nan family in Qin City? I've heard of it. The situation of Nan family and my family is somewhat similar..."

"The person in charge now is also the daughter of Nan family. The daughter of Nan family and my mother have contacts. My mother thinks highly of her. What's wrong?"

"..."

Qin Hongfei frowned and explained the situation.

The leader said coldly, "Nan family and Shao family have a good relationship, but if we don't talk about the previous incident, Shao family can't bear a grudge. Even if they do, they won't join hands with Nan family to make it difficult for you to buy materials. I guess there are other reasons."

Qin Hongfei said, "But apart from the intersection with Mr. Shao Qiye, I can't think of any other reason to offend the Nan family."

Several people thought about it, but couldn't figure it out.

So they just stopped thinking about it.

Tang Jinnan sent the materials Qin Hongfei wanted to Qinhuai Street in less than a few days.

Qin Hongfei drew a piece of paper - and then called Jiang Wan and Zhuang Yan over.

"This is..." Jiang Wan looked surprised. "

It's a sensor." Qin Hongfei replied, "A sensor for anti-reconnaissance watches." The inspiration was thanks to Dr. Niu's sensor.

"The reason why the anti-detection watch has the function of anti-detection is that it contains a sensing electronic device, and this thing can reversely sense the electronic sensor inside the anti-detection watch... Simply put, it is equivalent to a main device and a secondary device, but its function is not limited to this."

In the future world, this thing can be used to sense metal devices.

It can also sense the abnormal data of people coming in and out repeatedly around.
