Zhang Yu didn't let them talk any longer, and said to them solemnly.

"Well, now it's time for you guys to receive the reinforcement."

That's right, what Zhang Yu said was the perfect super soldier serum that he spent 10,000 Realm Coins to buy in the [Ten Thousand Realms Store System]. This serum has no side effects and a 100% success rate. With the guarantee of the system, Zhang Yu is not worried about any accidents.

With a wave of his hand, he took out the serum from the Sumeru ring.

Asuna and the others only saw a small box on the coffee table, and suddenly appeared out of thin air a small box that looked delicate and full of technology and looked like a medical kit.

They were all a little surprised to look at the box that suddenly appeared, Zhang Yu didn't tell them about the Sumeru ring, so they were surprised. Since it was too troublesome to explain these things before, Zhang Yu didn't explain much. Now that they've become subordinates of the system, they don't have to worry about anything.

The medical kit placed on the coffee table is silvery-white and made of alloy. The metallic box is faintly shiny, and the whole body exudes a noble and delicate atmosphere.

It's about the size of a regular laptop, and there are no gaps around the perimeter of the box, and there are no electronic locks in sight. However, there was a red button in the center of the box, and of course Zhang Yu knew how to operate it, so he pressed it gently.

"Poof."

There was a thud in the box, and a crack opened a third of the way. It turned into a lid and flipped back, revealing the contents of the box.

Inside sat five pieces of blue liquid, contained in a glass bottle that resembled the molecular structure of a DNA helix. And the outside of the glass bottle is also protected by a small hexagonal steel pipe frame, which looks very safe.

White cold air wafted out of the box, and it seemed that it also had a thermal insulation effect. If this cold state is not maintained, the Perfect Super Soldier Serum will gradually lose its effect if left at room temperature for a long time.

Zhang Yu picked up the layer of boxes, and sure enough, there was another layer below. There were also five perfect super soldier serums lying quietly inside, and he smiled slightly and put down the layer in his hand. Even if the system said that there was another layer underneath, he had to look at it to feel at ease.

Asuna's big beautiful eyes were wide open, and her hands were covering her small mouth that was slightly open in surprise. If the previous flying mecha was a surprise, now these things have shocked her speechless.

The two of them were also a little surprised, because Zhang Yu hadn't told them about this thing, but in their original world, this kind of enhancement potion was not uncommon, but the side effects were great.

Frowning at the beautiful crystal clear blue liquid, she thought it would be better not to risk Asuna and Yuphimia if there were side effects.

"Jade, what is this?"

Zhang Yu smiled slightly, and the scruples on his face were revealed.

"The Perfect Super Soldier Serum."

"The perfect super soldier serum? What's that? ”

Asuna looked at Zhang Yu suspiciously, and from the literal meaning, it was a potion for warriors. But they're just a bunch of beautiful girls, do they need these things?

Yufemiaa tilted her head to look at Zhang Yu and asked.

"Jade, you don't want us to inject these things, do you?"

Zhang Yu took out one of the injection guns in the box and looked at them with a smile.

"Yes, it's a potion that strengthens the body. Of course, I took it out for you to use. ”

This is a device that is specially used to inject medicines. You just need to load those serums on this gun, and you don't need to use those other syringes.

stroked the hair in his ears, looked at Zhang Yu helplessly and said.

"I don't want to inject this kind of thing, let alone how successful it is. Even if the reinforcement is successful, she will become the kind of female warrior with hard muscles. In that case, I don't need this booster. ”

In fact, she is not afraid of this thing, because she has a code, and no matter what accident occurs, it will not cause death. It's just that if the enhancement is successful, it won't touch the immortality of Code. But for her, who is immortal, this power is not very important.

When the time comes, she becomes a muscular woman, and at best, she adds a little strength. And the other two girls have also become like this, so if Zhang Yu meets a fragrant and soft girl in the future, won't he be able to control it all of a sudden.

I feel that I have a responsibility to be that special person, after all, she is also the oldest person among Zhang Yu's girlfriends so far.

When Yufemiaa heard that it would become like that, she also waved her hand at Zhang Yu in refusal.

"Ah, will it be like that? Then I don't want it either. ”

Only Asuna looked at Zhang Yu with firm eyes, without a trace of fear.

"Jade, come on. I believe you. ”

She has always been a swordsman in SAO, and she is considered the strongest female warrior in it. Now that she really has the opportunity to improve herself, she will certainly not let go of this opportunity. And Zhang Yu will definitely not harm them, he dares to come up with the potion, and he must have considered it carefully.

With Yuphimia, also give Asuna an affirmative look.

"You guys don't know how powerful this perfect serum is, and you don't know how precious it is. There is nothing more precious in this world. Let me explain it to you slowly. ”

Sure enough, Asuna was the most intimate, and he couldn't help but sigh in his heart.

"After the Superman Soldier serum injection, it stimulates the body's potential. It is hidden deep in the human body and is transformed into the "perfect" posture of the human body. Therefore, no matter who is injected with Superman Soldier Serum, they will have a high degree of intelligence, strength, agility, acuity, and physique that are far beyond the reach of ordinary people. ”

The best example of this is Captain America, but unfortunately they haven't seen it. If you talk to them about this, it will definitely arouse their doubts about themselves. When the time comes, if you know that you are just a virtual mission in the anime world, you will definitely be mentally stimulated.

Asuna and Yufimia under Zhang Yu's explanation. C. Still quietly looking at the fluorescent liquid on the table, the secret passage is really beautiful.

"After the injection, the average person is able to bench press 545kg without any assistance. In addition, the serum also strengthens the person's metabolic function, and can completely metabolize the lactic acid and other substances that cause fatigue in the muscles, which gives the strengthened person a completely unimaginable endurance.

Running a kilometer (26.6 meters per second) in less than a minute, etc., the top speed can reach up to 48 kilometers per hour. Moreover, the body cells of the strengthened person are immune to alcohol and toxins, and will not get drunk. It is also immune to most diseases, and the serum also slows down aging.

In other words, it can delay human aging, enhance human lifespan, and at least increase life expectancy by two hundred years. ”

After Zhang Yu finished introducing in one breath, the room fell silent.
