What women value most is their faces, and Superman Soldier Serum can not only keep their faces youthful for a long time, but also prolong their lifespan, which really makes them start to be tempted.

Asuna was not afraid, and after listening to Zhang Yu's introduction, she was even more moved.

"Jade, inject me. I've already decided. ”

No wonder it's called a super soldier serum, and if it's really strengthened, then I'm a super soldier. In this way, even if something unexpected happens in the future, I won't drag Jade down anymore. In this way, I also have the strength to be separated from my mother.

Asuna still has some psychological shadows in her heart for her mother Kyoko, otherwise how could such a powerful superhuman soldier serum not be able to deal with a woman. The Superman Soldier Serum is an existence that allows an ordinary person to become a superhero.

Zhang Yu secretly gave Asuna a thumbs up,。. With a reassuring look, he patiently explained.

"Rest assured. After the enhancement is successful, the human body's potential will be fully stimulated, and it will not become that strange muscular woman. ”

After hearing this, Yufemiaia also stood up and looked at Zhang Yu firmly.

"Jade, inject me too."

She didn't want to be a vase princess, and now that she had the Superman Soldier Serum, if she wasn't brave, she wouldn't be qualified to stand by Zhang Yu's side. From a long time ago, she has been known as the Princess of Vases. Now that I have this, I think it should be a little stronger than the physique of the Suzaku of the Pivot Tree.

Zhang Yu smiled and nodded.

"Okay."

Seeing that both of them agreed, he said it casually.

"Then give me a stitch too."

Although this is not indispensable to her, it is good to be able to increase her abilities. Otherwise, although he has an immortal body, he is still an ordinary person after all. And most importantly, if the two of them are strengthened.

But if she doesn't strengthen it, she may not be able to beat these two people in the future......

“…… Well. ”

This is a perfect superhuman soldier serum of a thousand world coins, and it feels like some kind of potion for rotten streets. also asked him to coax them to drink, Zhang Yu's mood was a little complicated at this moment......

Then Zhang Yu picked up the syringe gun in the medicine box and loaded it with Superman Soldier Serum. Asuna was shot first, injected into her white arm. A hexagonal red dot mark was left behind, and it was just an epidermal wound after the injection.

And then left a ,.。 on Euphemia's arm as well

In the end, he injected one himself.

At this time, Zhang Yu suddenly felt a hot gas flow in his body, which was different from the internal force. This air flow acts on every part of the body, even every cell.

The air currents continued to repair the aging and crippled and malnourished cells in his body, and Zhang Yu felt the wonderful sensation that made him want to moan. The body is repaired very quickly, almost in a few seconds.

He only felt that the cells in his body contained endless energy, bulging and filling his body. Even the internal force has grown greatly, is this the real transformation?

The Superman Soldier Serum was originally a very advanced enhancement potion, but after being optimized by the system, it has become even more perfect.

If there's one downside, it's that the power of the reinforcement isn't strong enough. In other respects, it has reached the pinnacle of perfection of ordinary human beings.

After the superhuman soldier serum entered his body, it did not strengthen Zhang Yu's muscles entirely, but was stored in various cells of the body in other forms. Since this is not his first time strengthening, the effect of the Superman Soldier Serrum's enhancement on him will not be noticeable.

Soon, Zhang Yu's breathing became lighter, and his body seemed to become much more relaxed. His mind was slowly becoming clearer, and his reinforcement was over.

Zhang Yu exhaled lightly, and a layer of greasy and slightly black toxin impurities emerged from the surface of his skin. He wasn't surprised, it wasn't the first time.

He turned to look at Asuna、., and saw that their reinforcements were very different from his own. Although I don't have to worry about the danger to my life, I still feel a little distressed when I look at their current situation.

After they were injected with the Superman Soldier serum, they felt as if a faint electric current was spreading all over their bodies from the injection in their arms, and then, suddenly, they felt as if their brains had been hit by a hammer, and the severe pain made them suddenly snort and faint on the couch.

Zhang Yu saw this situation on the instruction manual of the Superman Soldier Serum. So I didn't panic too much, just continued to wait silently for the moment when they succeeded.

This serum power seeped into their bodies, nourishing every cell in their bodies. In that feeling of comfort that is getting stronger, they are deeply infatuated. Even if he lost consciousness, his mouth was still slightly coquettish and moaning.

There is a difference between the perfect Superman Soldier Serum and the Superman Soldier Serum that has not been optimized by the system. It was very painful not to be boosted by the system Superman Soldier Serum.

If the human body is compared to a container, and the superhuman soldier serum is forcibly expanding the capacity of the container, then the taste will naturally not be pleasant. The Perfect Superman Soldier Serum, on the other hand, is like thickening and raising the walls of the container to make it tougher.

The words came out of Asuna's mouth.

"It's hot, it's itchy."

Then I saw the three of them unconsciously undressing, and they were scratching all over their bodies, and they were scratching blood stains. He also frowned, as if he was enduring the discomfort. But his hands were still silently stripping off his clothes, revealing his fair body.

Zhang Yu looked at them like this, and couldn't help but feel a feeling of heat in his heart.

It's simply fascinating.

But when he saw the blood marks that had been scratched, he was a little worried. I found that the scars began to fade slowly, healed, and disappeared.

He went to help them put on their clothes first, but he was afraid to disturb their strengthening process.

So he could only silently close his eyes, meditate on the Qingling Treasure, and suppress the desire in his heart.

After Zhang Yu closed her eyes, Asuna and her whole body began to break out in a cold sweat, and all the muscles and veins in their bodies were frantically transforming and strengthening. The bones, internal organs, and faint cool sensation also came, making their moaning sound even more charming.

Inside them!

The air currents that had been transformed from the blue liquid serum swept through the body like a tidal wave.

Crackling!

The joints of the bones also faintly sounded. Under the transformation of the perfect superhuman soldier serum, it began to strengthen rapidly.
