Qin Hongfei took a quick look at the situation. Several bulletproof vests were basically scrapped and only had the value of recycled materials, so they had to be redone.

The only thing she needed to do was the bees.

Because the technology was far beyond today's, even though Qin Hongfei had explained the drawings to Jiang Wan and the factory staff, they still only had a vague understanding, so she had to do it herself. As for the other items, they could be handed over to the factory staff.

Tu An'er told her that thanks to these equipments, Tangqi's cooperation with foreign countries in medical equipment in the past two years has far surpassed other peers.

The public security abroad is completely different from that at home.

Especially those who work for enterprises are more likely to be targeted. In the past ten years, before she met Qin Hongpin, Ms. Tang's biggest headache every year was foreign orders. Sometimes she had to carefully select people to send, so as to avoid and reduce casualties as much as possible. However, even if she was cautious,

"If you meet those who don't care about their lives, you will be injured every time you come back, even if you don't die."

"Only in recent years." Tu An'er said in a brisk tone, with a bright smile on her face, "Every time everyone goes abroad, they come back smoothly. At most, there is damage to the equipment, and at the very least, it is only a minor injury. Everyone says that it is a pity for your equipment."

Tu An'er's eyes are filled with gratitude.

She is also an orphan of Tang Qi, and the people she knows are all from Tang Qi.

For the orphans of Tang Qi, they have no father or mother, but they are like a big family, and no one wants to see injuries.

Qin Hongfei said, "Equipment is only auxiliary, the most important thing is your own ability, not to mention, Ms. Tang paid for it."

She is not greedy for this credit.

Having equipment will definitely get twice the result with half the effort, but it also depends on who it is.

For example, if you use the equipment first, even if you encounter a bad guy, you can fight ten of them.

If it were Qin Hongfei herself, even if she had the best equipment, if there was no one to protect her, she would probably be in trouble, so what she heard most from the teachers in her previous life was that you should never let yourself fall into that kind of situation.

Tu'an'er said seriously, "You don't have to refuse. They are definitely capable of it, but without your equipment, everyone would be injured."

Although Ms. Tang would allocate a sum of money to Qin Hongfei for equipment every year, and also provide sufficient research funds to the First Institution.

But if everyone had any needs or ideas about equipment in private, they would be conveyed by Tu'an'er, and Qin Hongfei would basically satisfy them if he could.

So whether it was Qin Hongfei's credit or not.

Tu'an'er knew it in his heart.

After a tour of the factory, Tu'an'er told everyone's requirements this time.

Qin Hongfei drew pictures for all the bees that could be satisfied, and took away the remaining bees. "I'll have Meng Yu send them back after they're fixed."

Tu'an'er responded from her words, "Will you stay in Yangcheng for a long time this time?"

Qin Hongfei said, "Three days."

Tu'an'er was even more surprised. Three days -

for busy people like them, not to mention Qin Hongfei, even she herself was very busy. Sometimes she had to thank God for being able to take a half-day break. Qin Hongfei came here specifically to stay for three days.

I haven't heard about what happened to the Qin family.

She asked curiously, "What happened?"

Qin Hongfei said, "It's a secret!"

When she came out of the Tangqi factory, she saw Yu Chi talking to someone. The two were smoking. When they saw them coming out, they immediately threw the cigarette on the ground, stepped on it, and then threw it into the trash can.

"Miss Qin." Zhang Liang smiled toothily.

More than an hour later, outside the main entrance of Yangcheng University, Qin Hongfei was sitting in the car with her head down playing Xiaomi on her mobile phone. After waiting for about ten minutes, a figure walked out of the main entrance and came this way. Soon, Yu Chi got out of the passenger seat and opened the door for others, and at the same time he changed to the vehicle behind.

There was an extra hand on her head, gently rubbing the top of her hair.

Qin Hongfei looked up at him, moved to the right, and made room for him on the left. She looked at the materials in his hand curiously, "Are you giving a lecture?"

Tang Jinnan nodded slightly, got in, and closed the car door. Seeing that she was curious, he showed the materials to her.

He was invited by the school.

Tang Jinnan has no interest in giving lectures.

However, the institute arranges trainees to come and give lectures every year. He and Qin Yan play rock-paper-scissors and take turns.

"It should have been my senior brother's turn." Tang Jinnan said calmly, "But he has something to do temporarily, so please let me take his place."

"Conditions?" Qin Hongfei was curious.

Tang Jinnan glanced at his girlfriend and said frankly, "He will take my place three times in the future."

One time for three times, a steady profit!

Don't say that we all grew up together, so what's wrong with helping each other? Everyone who grew up in the institute is a shrewd person, so realistic! You can help, but you have to talk about the conditions!

Even brothers clearly divide the bills.

Qin Hongfei praised her boyfriend.

"Let's go, I'll take you to see something." Tang Jinnan stretched out his hand and rubbed the back of her neck, just like teasing a kitten.

Experimental building.

The building that the research institute belongs to has a history of more than a hundred years.

Tang Jinnan asked Zhang Liang to take Meng Yu and Yu Chi to a nearby snack bar to stay, and took Qin Hongfei in. They quickly swiped their cards to enter a laboratory building. When Qin Hongfei saw this place, she was reminded of a sense of familiarity and paused.

This is the most central area of ​​the experiment, and the researchers are busy with their own things.

Expensive equipment and experimental equipment can be seen everywhere.

Although Qin Hongfei is also a researcher, her direction is different. She does not need to use these equipment, so she has never been here. This is her first time coming in.

And she is very familiar with these things.

In her previous life, after feeding and getting familiar with the teachers every day, she was slowly able to enter the research building.

There, it was also like this, with various mechanical equipment.

Thinking of Master Bai...

Qin Hongfei suddenly missed the scenes of teachers practicing Tai Chi, Ba Duan Jin, and standing on the poles in the courtyard during holidays...

Tang Jinnan led Qin Hongfei into the room, and soon they passed by a small room. Through the transparent glass, Qin Hongfei saw Qin Yan, who was wearing a white coat and working on a project with several people. When he looked up and saw Qin Hongfei, Qin Yan: "?"

Soon...

Tang Jinnan raised his hand and knocked on the door, and then led Qin Hongfei into the room.

Qin Yan was slightly surprised and asked, "How come I didn't know when you came back?" He then asked, "Why did you bring her here?" He was asking about his childhood friend.

Tang Jinnan said, "Where is the thing I studied before?" and then stretched out his hand.

Qin Yan seemed to understand something immediately, and looked at Qin Hongfei and said, "That's great, help me give some advice."

Then he put on gloves and took two small tubes from the sample area and handed them to Tang Jinnan. Tang Jinnan looked at the sunny area and turned around to hand them to Qin Hongfei.
