Qin Kong shook his head, "I need plant dye."

"Plant dye?"

"Look!" Qin Kong pointed to the information on the computer, "I now know the detailed ratio of hair dye."

Qingxiang looked carefully at the information for a while and the ingredients, proportions, effects, and side effects of each hair dye were clearly clear!

He stared at him with his eyes wide open, "Teacher Qin! How did you do it?"

"Well..." Qin Kong looked at her eyes that didn't know whether she was looking at the gods or the psychopath, "It's just... I suddenly got to know, do you understand?"

"I understand, understand." Qingxiang looked at him and nodded blankly.

What else can I do if I don’t understand? This is not the first time he has learned it!

Qingxiang looked at the detailed information on the computer screen again, "Plant dyes, although the extraction is complicated, we still have experience in plant extraction. We should be able to make it out soon.

But yesterday you said that no chemicals were added, and plant dyes were not colored well?"

"I have the skills to solve the coloring properties." Qin Kong said confidently, "I now master the technology of perming and dyeing without damaging my hair."

"Really?" Qingxiang's eyes were shiny, and she couldn't help but touch her hair again. She felt very dynamic and full of vitality. She felt very healthy when she touched herself!

"Can we sell this plant dye?"

"No." Qin Kong shook his head, "Because others don't have my skills, they can't achieve the effect. They still need to add chemical products to develop colors. Plant dyes are specially provided to me."

"I really want to try it."

"I tried a variety of hair dyes, but they didn't pass. These hair dyes are harmful to the hair. I need completely pure plant dyes."

"Um."

"Make the plant dye first, and I will accumulate some experience here. At that time, try to use plant dyes instead of chemical dyes in the perming agent, which can also reduce the damage to the hair."

"Yeah." Qingxiang nodded, "Then you know the formula of perming agent, don't you need Dr. Du?"

"Of course I need him!" Qin Kong widened his eyes, "Now I need him even more! Because I want plant dyes! You can't let me squat in the laboratory every day to study this, right?"

"Then I'll go to Huacheng tomorrow."

"Wait." Qin Kong sat down again, "I'll sort out the information and you'll take it over tomorrow. Dr. Du will come."

Liang Ange is indeed not worried that Teacher Kong and Sister Qingxiang will stay alone at night, but they are not used to sleeping alone.

Twist and turn on the bed, and waited until late at night, and finally couldn't help calling him.

It was followed by a female voice: "Ange."

"Sister Qingxiang!" Liang Ange said in surprise, "Where is Teacher Kong?"

“Busy.”

"What are you busy with?"

"What do you think?"

"Sister Qingxiang!"

"Hahaha..." Qingxiang covered her mouth, "He wrote the decoction information in the store and told you by the way, your empty teacher has increased the price again!"

"ah!"

"I slaughtered 30,000 yuan with my hair! Do you want to have a video and see the new hairstyle he made for me?"

"OK!"

"Forget it! I'll just videotape with Teacher Chen first."

Liang Ange hung up the phone, jumped out of the bed, changed his shoes and went out.

When I arrived at Kongfayi, the shops around me were closed, and Kongfayi still had the door open and the lights were on.

Liang Ange walked in and heard the sound of typing. He looked at the sofa again and fell asleep with Qingxiang tilted.

After staying for a while, Liang Ange walked to Qingxiang and looked at her hairstyle. He then reached out to help her straighten her and lay down, and admired her seriously, "Well, it looks good! Don't do it for me first when the price increases! Excessive!"

Liang Ange walked to Qin Kong again, and Qin Kong was typing seriously, without feeling that there were more people around him.

I reached the edge and didn't touch the hair dye, but I felt a soft one.

Huh?

Qin Kong quickly shrank his hand and looked up at Liang Ange. It turned out to be his girlfriend!

Smiling...

Qin Kong touched it again.

Liang Ange opened his hand with a snap, "What are you doing?"

"Ange!" Qin Kong stood up and said happily: "I've raised the price!"

"I see."

"Oh!" Qin Kong looked at the sofa, "Oh! Actually, you can go back and wait! Why are you asleep here?" He looked at Liang Ange again, "Why are you here? Don't worry?"

"Why don't you perm your hair first?"

"I don't know either!" Qin Kong opened his eyes wide, "Just always said that he wanted to perm the newly grown hair. As soon as I got started, I would..."

"Just what?" Liang Ange looked at him.

"I decided I'd like to raise the price!"

"Then you are really willful!"

"That's right!" Qin Kong hugged her and said happily, "Do you know? I can really perm and dye it as I want now without hurting my hair!"

"Really?" Liang Ange raised his head and looked at him with bright eyes, without any doubt, "I knew every time you raise the price, it makes sense!"

"Yeah!" Qin Kong nodded vigorously. As expected, his girlfriend was the cutest! He chose to believe everything that was unreasonable to him. Maybe because she was an elf, she liked magic!

Thinking of his regret that he could not make perming products that would not hurt his hair before, Liang Ange said happily: "Is it possible that you can develop perming products that should not hurt his hair at all?"

Qin Kong thought for a moment and shook his head, "It's not possible yet. It's mainly my skills to avoid damage to hair."

Qin Kong looked back at the information on the computer, "But now I have fully mastered the formula and function of the perming agent. Such detailed data comparison can at least greatly improve safety and reduce damage.

Our product development has passed the initial stage! It will greatly speed up the process!"

"Wow!" Liang Ange glanced at the information on the computer. Although he couldn't understand it, he felt so awesome! "Teacher Kong, you are so awesome!"

"Yes." Qin Kong kissed her. If the divine principles had not been suddenly upgraded, she should have been dyed first.

"Then can you perm and dye me now? You have long said you want to perm and dye me!" Liang Ange said expectantly.

"Well..." Qin Kong looked at her, "I have mastered hair dyeing techniques that do not hurt my hair, but I need pure natural plant dyes. This one needs to be developed and produced. Now I can only perm my hair."

"Then you burn it first!" Liang Ange looked at him with bright eyes.

Qin Kong looked at her for a while, "Dr. Du's family stopped him from joining us."

"ah?"

"Mr. Qing is going to Huacheng tomorrow to convince his wife. I want to sort out the information and let her take it over. As long as Dr. Du sees it, no one can stop him.

His wife is also a doctor. If you can take a look, you will understand that we are not lying. We will make epoch-making products!"

"Yes." Liang Ange nodded, very happy for him.

"You go to bed upstairs first, I will organize the information about the perm." Qin Kong gently put her hair behind his ears.

"Um."

Qin Kong let her go, and went to the warehouse to take out the softener and shaping agent. Shenli also gave a detailed formula.

He also stated: Users only need elastic waves to shape as they like, without the need for the inferior products of Blue Star.

Qin Kong smiled, this APP is a bit stupid!

Didn't you see that he was using it?

He doesn't need it, but Qin Si needs it!

Shenli probably thought this user was a little stupid, but he still showed the ratio and side effects of each bottle of perm potion over and over again.

Qin Kong recorded it carefully on the computer.

During this period, Qin Kong had already bought a lot of samples in the store.

Liang Ange looked at him, smiled and went upstairs to take a blanket down, covered Qingxiang, and took off her shoes.

He pulled the barber chair next to Qin Kong and sat next to him watching him write the materials attentively. Such a boyfriend had to show off to the chemistry teacher and took a photo and sent it to his father.

In the middle of the night, Liang Mingze actually replied: What are you doing?

Liang Ange replied: Teacher Kong is studying products.

Liang Mingze gave a thumbs up and said: I advise him to go to bed early, so you can go to bed early, and don’t stay up late.

Liang Ange sweetly looked at Qin Kong's serious side face, then looked at the chemical names and data on the computer, and his eyelids started fighting, yawned, and fell asleep with his head tilted against his leg.

From time to time, drunk people were laughing and watching movies, because Liang Ange pulled up the curtains and closed the door, and no one noticed that Kongfayi was still on.
