After Lu Yu waited for Chen Xiaofei to leave, he returned to the room, opened the laptop, searched for the equipment he needed on the Internet, and checked the specific parameters.

He didn't pay attention until it was dark, but Zhang Kexin and Qianqian came over to ask him to go out to eat together, and he knew that it was past dinner time.

Lu Yu followed them to the restaurant outside and asked shallowly:

"We'll play a game later, do you want to play together?"

Lu Yu pulled out a chair and sat down, and glanced at her:

"And then wait for you to me down and crawl on the ground with a troll?"

Qianqian also thought of the last time we formed a platoon together, as soon as the little temper came up, I hit my teammates several times, covering my mouth and laughing.

Zhang Kexin assured on the side: "Don't worry, this shallow will definitely not target you." ”

Lu Yu nodded thoughtfully: "Well, yes, I believe it, but you will target me, be as witty as me, and don't play." ”

Zhang Kexin cut off, carefully thinking about being seen through, but did not succeed:

"Eh, surnamed Lu, I heard that you like Miss Gufeng, is it true?"

Lu Yu's expression was obviously stunned: "Who said that?" ”

Zhang Kexin asked: "You don't care who said it, just ask if you like the young lady who dresses up in ancient style?" ”

Lu Yu couldn't help but think of the appearance of Shi Zixuan and Qin Xiaomian when they were wearing ancient long skirts, especially when they accompanied the two girls to Qingcheng Mountain not long ago, under the hazy moonlight, the two girls wore plain white dresses.

Thinking about those pictures, he nodded: "Well, I like it a lot, why are you asking this?" Do you have an old lady you would like to introduce to me? ”

Zhang Kexin glanced at it silently:

"No, even if there is such a young lady, it is impossible to introduce it to you."

Lu Yu was puzzled: "Why?" ”

Zhang Kexin: "It's not small at all. ”

Lu Yu chuckled lightly and ate his meal with his head down.

……

Zhang Kexin said again: "By the way, can I borrow it from your home this weekend." ”

Lu Yu raised his head: "Haven't you been using it?" ”

Zhang Kexin: "This weekend's birthday, I want to invite my classmates and friends from the school to get together. ”

"You're spacious enough, don't go out, order some meals and come back, how appropriate it is to eat and drink."

Lu Yu: "Weekend? If memory serves, it's Wednesday, right? ”

Zhang Kexin: "Yes, I'm going to invite friends and classmates on Saturday, don't say no, don't say you're not available." ”

Lu Yu thought for a while: "Use it as you like, just ask the cleaning company to clean it when you're done, but I'm really not sure if I'm free, and I'll have to go out tomorrow." ”

Zhang Kexin: "Brother Birdman, someone as good as you must have time, right?" ”

Lu Yu nodded: "Okay, I'll try to come back." But then again, how old are you? 21？ 22？ ”

Zhang Kexin squinted: "You care about me?" Also, am I that old? ”

Lu Yu looked at her seriously, and then nodded: "Yes." ”

Zhang Kexin squeezed out a few words from between his teeth:

"I just turned 20!"

Lu Yu was a little surprised: "Tsk, old aunt." ”

The chopsticks in Zhang Kexin's hand are about to break:

"You don't want to eat this meal, do you?"

Lu Yu turned his head: "Shallow, this braised pork ribs taste good, you can taste it, it is smooth but not greasy, soft and delicious, especially suitable for girls, super beautiful." ”

Seeing that Qianqian and Zhang Kexin were both attracted by the ribs, they deliberately suddenly remembered something:

"Oh, by the way, Zhang Kexin, our company has just developed a new product, and I think it is especially suitable for you."

Zhang Kexin's eyes lit up and she became curious, which product of the pink, white and black company is not easy to use?

Asked, "What product?" ”

Lu Yu glanced at her slowly:

"The effect of wrinkle removal is particularly good, and you can never do without it after using it once."

Zhang Kexin's expression stiffened on his face.

took a few deep breaths, suppressed the anger that suddenly rose in his heart, and his milk hurt, and covered his chest and asked for help:

"Shallow, look at this surnamed Lu, I kindly ordered takeout and invited him to eat, but you see him... He... He's not a human being! ”

Qianqian was amused by the two of them, and when she heard Zhang Kexin complaining to herself, she hurriedly stuffed a piece of ribs in her mouth.

Zhang Kexin was decisively attracted by the ribs, and hummed:

"Huh? Hello! ”

After the three of them talked and laughed and finished eating, Zhang Kexin and Qianqian went back to school.

Lu Yu went back to the room to read a book, and by the way, he told Deng Qiang to prepare some materials and go over to pick them up tomorrow.

……

Lu Yu, who woke up, finished washing up and went to the refrigerator in the living room to get a fruit.

went out eating fruit, took the subway to the pink, white and black company, and called Deng Qiang.

After a while, Deng Qiang came out, and after saying hello, Lu Yu directly asked him to take it to get the materials, which he would use today.

When Deng Qiang received the news yesterday, he asked people to prepare overnight, he knew that it might be related to the new anti-wrinkle and wrinkle removal products, so he didn't dare to delay.

Deng Qiang did not prepare all the materials, only a part.

In the past, when I was synthesizing irritating substances that replenish water and substances that absorb pigments, I bought a variety of materials for experimentation.

Some of the materials are useless and are still in rudimentary labs.

It didn't take long to get the materials, Lu Yurang loaded them in a car in the company, and drove to the simple laboratory.

……

I hadn't come to the humble laboratory for a while, so Lu Yu first did a rough cleaning, and then moved the materials from the car.

After moving the materials, I rested for a while before officially starting to synthesize the new material.

If this new material is to be used on the skin, it is definitely not a metal material.

Of course, it is not an inorganic non-metallic material that is insoluble in water.

It can only be counted in the classification of organic polymer materials.

This organic polymer material is, by its very nature, a complex silicon-based polymer.

There are two reasons why it is wrinkle-resistant and wrinkle-free.

One is because it has the elastic and mechanical properties of youthful skin.

When applied to the skin with this delicate and silky material, its elasticity quickly reduces the degree of skin contraction, resulting in a quick appearance of wrinkles.

But this kind of wrinkle removal is only physical, it is also temporary, and it cannot be really wrinkled.

Just tighten the skin and temporarily lighten wrinkles.

……

To really get rid of wrinkles, that's the second reason.

This polymer is also irritating, stimulating the cells of the dermis layer of the skin to accelerate the absorption and production of collagen.

The reason why the skin has wrinkles is because after the age of 25, the skin metabolism decreases, and the amount of collagen in the protein decreases.

The irritation of this polymer material can well stimulate the absorption and production of proteins, especially collagen.

This irritating and hydrating irritant works the same way, and after using it, you can just eat more collagen-rich foods.

In other words, using this polymer material, not only can wrinkles disappear quickly, but as long as you eat more collagen-rich things such as white fungus, pig trotters, fish maw, egg white, fish, etc., you can accelerate absorption.

In this way, the surface layer of the skin is replenished with collagen, and wrinkles are truly removed.

With consistent use for a period of time, coupled with a reasonable diet, you can remove wrinkles from the outside to the inside.

……

The synthesis of this polymer material is not complicated.

It only took a few hours for Lu Yu to synthesize it with experimental equipment.

After stopping to rest for a while, Lu Yu drove out for a meal, and then came back to use the cells on the surface of the skin to verify the properties of this polymer material.

After another few hours, Lu Yu looked at the results of the experiment and nodded with satisfaction.

The question remains as to what substances to add to this material.

These substances are of little use, do not cause any damage to the skin, and do not affect the properties of the polymer.

This is also the next experiment that Lu Yu will do.

This job is no easier than the experiment just now.

Synthetic polymers, Lu Yu has long had ideas, and there are primary scientific and technological materials as a reference.

But with the addition of useless substances, there is no reference to this.

Nor is it within the scope of learning.

Lu Yu could only add some common Chinese herbs and other ingredients one by one.

It is not okay to add it at will, and if you are not careful, it will affect the performance of the polymer or have an impact on the skin.

At this time, Lu Yu deeply felt that Ma Dan, why is it more difficult to make trouble than research?

Synthetic new materials are not so troublesome, and if you want to make trouble now, it will be even more difficult!

Until late at night, Lu Yu didn't find a suitable plan.

Plus I'm a little sleepy, so I'm going to rest in the lab and continue tomorrow when I get up.

……

When he woke up on the laboratory sofa, Lu Yu had a little backache.

I got up and exercised my muscles before driving out to eat.

When I came back, I bought some food and ate it when I was hungry.

Jump into the experiment.

This time, a suitable solution was finally found before dark.

More than a dozen flavors of Chinese herbs are added, as well as some other organic ingredients.

This blend will not harm the skin or affect the wrinkle removal effect.

Lu Yu looked at the unidentified substance in front of him and couldn't help but smile.

Such a complex ingredient, when analyzed, will kill those researchers, right?

A second of silence for their brain cells.

When the time comes, the product is produced into a latex-like viscous liquid, and some spices are added to make the taste not so unpleasant.

Where you need to wipe it!

Impeccable and just perfect!

Such a product is simply an aphrodisiac for a slightly older female consumer.

Let me ask you: What are you going to resist?

Removes wrinkles, prevents wrinkles, regains youth, and blooms beautifully!

Just ask, do you want to?

To be, or not to?

Be louder, you can't hear it!

……

Such a magical product, when the time comes, it should be a little more expensive, it should be fine, right?

Consumers should be able to accept it, right?

When overseas markets are opened, the price of this product should be increased, and the price should be increased fiercely.

I believe that even so, foreign female consumers, especially European and American female consumers, will definitely flock to it.

There is no way, the skin of Europeans and Americans is born with wrinkles a little earlier.

When the time comes, put this product in front of them and say:

"Dear, remove wrinkles, free shipping!"

Aren't they crazy?

Thinking about it, Lu Yu couldn't help but have an aunt-like smile on his face.

Very good, a lot of small money, waving his hands enthusiastically at himself.
