At about 17 o'clock in the afternoon, the underground laboratory of the science and technology villa.

Two hours ago, Ye Hua was still a sissy with a fresh white face, but now, after being reflected by ultraviolet light, his image has returned to the way it was before the controllable mutation.

But there is still a big difference, he now looks younger, and the most obvious change is that his eyes, in addition to having the sharp edge characteristic of young people, also have a touch of depth.

Although he has gone through menopause, the temperament of the superior he has cultivated over the years has not disappeared, which makes him obviously different from ordinary young people.

Menopause is more attractive than before.

Now that Ye Hua has completed ultraviolet exposure, it is difficult to turn back into a little white face and little fresh meat again, because the skin has produced melanin deposition after ultraviolet exposure.

Unless he goes in and transforms again!

But that nightmare made him never want to do it again, even if it was a dream, it was too real.

At this time, he was in the biological laboratory, and the purple cocoons in the cylindrical biological chamber cabin had already completed degradation and were extracted by the aqueous solution.

Ye Hua sat on the edge of a laboratory table, the white light source illuminated the entire table, and he drew the blood filled with injections from his body again.

The potent regeneration factor is in the serum, which is a pale yellow liquid in the upper layer when the blood is naturally coagulated, and the amount is not much; Plasma is a blood that is added to a test tube with an anticoagulant and centrifuged to stratify into three layers, the upper layer is light yellow liquid plasma, the middle layer is white platelet white blood cells, and the lower layer is red blood cells.

Almost finished the last dose of serum separation, Ye Hua said: "Xiaoyin, let them all come down!" ”

This time it's really going to be an injection.

It is worth mentioning that Xiaoyin will not inform Qiao Wei directly, although she can do so, Ye Hua requires that she must tell Uncle He.

It seems like an extra move, Ye Hua, as a thoughtful person, knows that he must do this, otherwise Uncle He, the big housekeeper, will fall into a very awkward position, and he is indispensable.

After a few minutes, Qiao Wei, Lan Ping, Shana, and Kitagawa Ayako came to the underground warehouse together.

It's not the first time they've come down, but it's the first time they've entered the Life Lab.

Although it is called an underground warehouse, it is actually a whole underground floor, and the actual area is 40% larger than the upper floor, and it is completely Ye Hua's private research institute.

"It's a little cold, weird and eerie." Qiao Wei said timidly.

The life laboratory is still quite special, with cold light sources, biological hazard icons ☣ that can impress at a glance, large and small side-by-side test tubes, many organic life needs ultra-low temperature environments, and so on.

In short, the women did not resist but did not like such an environment.

With the sound of an air valve, the transparent glass isolation door automatically opened horizontally, and the girls came to the laboratory where Ye Hua was.

"How is your skin ......" Qiao Wei was slightly stunned when she saw his current appearance, and Kitagawa Ayako and the others were also puzzled.

"Don't make a fuss, a specific wavelength of ultraviolet light hits ......," Ye Hua briefly explained this change to the women.

"A man with fair skin and tender skin, I'll take ......" Ye Hua made an exaggerated expression, causing the women to cover their mouths and laugh, Lan Ping grinned and said: "I think it, it was quite beautiful before, and the tender skin feels strange." ”

Ye Hua's mouth trembled when he heard this, he rolled his eyes, shook his head with a wry smile helplessly, didn't bother to pay attention to them, put on a new pair of sterile gloves, and went to the corner side of the wall to open the liquid nitrogen low-temperature condensation cabinet placed here.

Even in the middle of summer, there was still a long way away, and when Ye Hua opened the liquid nitrogen condensation cabinet, the girls still felt a chill coming.

"By the way, what did you tell us to come down for?" Shanna asked curiously, staring at the four closed catheters that Ye Hua took out from the condensation cabinet with big eyes.

"Injection!"

"Injections?"

The atmosphere was suddenly quiet, Ye Hua couldn't help but look at them, and saw that the women's faces were strange, which also made him look helpless and couldn't laugh and cry: "Hey? No...... What's going on in your head all day? What a shot! ”

"With what?"

"With a needle, of course!"

"What needle?"

"Of course, butt pins!"

"How?"

Ye Hua was holding five tubes of solution and throwing it at room temperature, the substances in the catheter quickly began to liquefy, and the corresponding biological factors were contained inside, and the stripped serum needed to be mixed with it for effective injection.

"Of course, it's a ...... Wait a minute..."Ye Hua replied as he did it, and suddenly stopped, he felt that something was wrong, and he was inadvertently thrown into the unknown territory by these women.

Glancing at them, he said lightly: "Do you want fair and delicate skin?" Do you want to stay in Fanghua or don't want to? ”

The women were slightly stunned.

"You mean it's okay now? No, didn't you say at noon that it would take half a year at the earliest......"

"Okay, then in half a year." Ye Hua said and was about to take the things back and freeze them, and when the women saw this, they suddenly said in unison: "Don't, I was wrong, I want it now, I want it now." ”

Suddenly very well-behaved, dependent and submissive, excited and undisguised.

"That's right." Ye Hua came back satisfied.

Three or two minutes passed in a blink of an eye, and he successively introduced five tubes of mixed serum solution into five syringes, and the women also quietly watched his skillful operation, and saw the five tubes of liquid as if they were rare treasures.

At this moment, Kitagawa Ayako suddenly said weakly: "Do you really want to get an injection?" Can't I take it orally? ”

"The oral effect is reduced by 95%, so I can only give injections." Ye Hua glanced at her, and suddenly smiled strangely: "Hey, I'm surprised, you are not afraid of such a thick and long needle, but you are afraid of such a thin and short needle?" ”

Ayako Kitagawa rolled her eyes angrily, "If I could, I'd rather choose the former." ”

"Yes, size is not the key, length is not a problem, the key is a cool and a pain." Ye Hua grinned, and after a few words, he gradually retracted his demeanor, and was ready to finish, Ye Hua stared at the women seriously, "This is a priceless treasure, and it is extremely difficult to make, whoever comes first, hurry up!" ”

"I'll go first." Lan Ping stepped forward to his side.

"The posture is wrong, raise it a little higher, and then lift it up a little more." Ye Hua said with a face full of instigation, his hand itched and couldn't help but "snap" it, and the mellow feel was still so good.

"Oh, I hate it~~ You just have ...... heart" Lan Ping glared at him resentfully, "This posture is very tired, get an injection quickly!" ”

"Awkward, you, how can I get an injection when I twist around?" Ye Hua said seriously.

"Stinky rascal..."muttered a sentence, Lan Ping honestly remained motionless.

Ye Hua put away his playful heart and began to focus, and the characteristic of his concentration was also obvious, that is, he didn't speak.

Holding a sterile cotton swab stained with disinfectant and wiping it on the part of the fair-skinned and round buttocks, Lan Ping immediately felt a touch of coldness coming from behind, at this time, Ye Hua pricked a needle, Lan Ping bit her lips lightly, and was more silent than these eyes.

Kitagawa Ayako, who was on the side, couldn't help but quickly close her eyes and shift her gaze, Qiao Wei looked at her in amazement: "No, are you really afraid of injections?" ”

"I've been scared since I was a child."

Seeing that Kitagawa Ayako's pretty face was solemn and timid, Qiao Wei couldn't help but "poof", and hurriedly covered her mouth and smiled, just now she really thought that the two of them were flirting, but she didn't expect that she was really afraid of injections.

"Okay, who's next." After Lan Ping finished her work, Ye Hua picked up another syringe and a sterile cotton swab and aimed at the three of them.

"I'll do it." Shanna took the initiative to catch up.

And then there's Jovi.

Finally, there is Ayako Kitagawa, although she is very afraid of injections, she still can't resist the temptation of beauty and longevity.

After the injections for the women, Ye Hua put away the last powerful regenerative factor reagent and put it in a liquid nitrogen ultra-low temperature condensation cabinet for sealed cryopreservation, which was reserved for Kara.

"When will it work?" After the injection, Qiao Wei also had absolute trust in him, but she still couldn't help but ask.

"Two to three days later, this is an allogeneic transplant, and the regeneration factor can last for about 12~15 years, and then it will be made for you, and then you can fight again." Ye Hua said, not forgetting to emphasize again: "Keep your mouth tight, you know?" ”

"Got it, yes!" The women are happy in their hearts, and they are well-behaved in unison, full of tacit understanding.

"Master, Uncle He has already prepared dinner."

"Let's go, go up, don't touch the experimental equipment, Cortana is not honest with you, go back to the bedroom and be the first to clean you up."

"Hmph..."
