Zhang Yu did not let them chat anymore and said solemnly to them.

"Well, it's time for you to accept reinforcement."

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

He waved his hand and took out the serum from the Sumeru Ring.

Asuna and the others saw a small box that looked very delicate and technological, looking like a medical box appeared out of thin air.

They all looked at the box that suddenly appeared in surprise. Zhang Yu had not told them about the Sumeru Ring, so they were surprised. Since it was too troublesome to explain these things before, Zhang Yu did not explain much. Now they have become subordinates of the system, so they don’t need to worry about anything.

The medical box placed on the coffee table is silver-white overall and made of alloy. The metal-like box reveals a faint luster, and the whole body exudes a nobility and exquisite atmosphere. The system produces a box that is not simple.

Its size is about the same size as an ordinary laptop, and there is no gap around the box, and no electronic lock is seen. However, there is a red button in the center of the box. Of course, Zhang Yu knew how to operate it, so he pressed it lightly.

"Puff."

The box sounded, and a gap was cracked from one third of the box. It turned into a box lid and flipped backwards, revealing the things inside the box.

Five blue liquids are quietly placed inside, loaded by a glass bottle with a similar DNA spiral molecular structure. There is also a small hexagonal steel pipe frame on the outside of the glass bottle, which looks very safe.

White air conditioning quietly floats out of the box, and it seems that it also has a thermal insulation effect. If this low temperature is not maintained, the perfect super soldier serum will gradually lose its effect when placed at normal temperature for a long time.

Zhang Yu picked up the box, and there was indeed another layer below. Five perfect super soldier serums were lying quietly inside. He smiled slightly and put down the layer on his hand. Even if the system said that there was another layer below, he would have to look at it before he could feel at ease.

Asuna's beautiful big eyes were already wide open, and her hands were also covering her small mouth slightly opened because of surprise. If the flying mecha was quite surprised before, these things now made her speechless.

C.C. and Euphemia were also a little surprised because Zhang Yu had never told them about this thing, but in their original world, this kind of enhancement potion was not uncommon, but the side effects were very big.

C.C. looked at these crystal clear and beautiful blue liquids with a frown. If there were side effects, she thought it would be better not to take the risk of Asuna and Euphemia trying it out.

"Yu, what is this?"

Zhang Yu smiled slightly, and of course he also saw the concerns on C.C's face.

"Perfect Super Soldier Serum."

"Perfect Super Soldier Serum? What is that?"

Asuna looked at Zhang Yu in confusion, literally speaking, it was a potion prepared for the warriors. But they were just a group of beautiful girls. Do they need these things?

Euphemia asked, tilting her head and looking at Zhang Yu.

"Yu, you won't want us to inject these things, right?"

Zhang Yu took out an injection gun from the box and looked at them with a smile.

"Yes, this is a potion that can strengthen the body. Of course I took it out for you to use."

This is a device specially used to inject drugs. Just load the serum on this gun, and you don’t need to use other syringes.

C.C. tweaked the hair in his ears and looked at Zhang Yu helplessly and said.

"I don't want to inject this kind of thing, let's not talk about the success rate of this thing. Even if the strengthening is successful, I will become a kind of hard-hard female warrior. If that's the case, I don't need this strengthening potion."

In fact, she is not afraid of this thing, because she has Code, and no matter what accidents occur, it will not cause death. However, if the reinforcement is successful, it will not touch the immortality of Code. But for her immortal, this power is not very important.

By then, she will become a woman with hard muscles, at best, increase some strength. If the other two girls become like this, then if Zhang Yu meets a fragrant and soft girl in the future, wouldn’t she be able to control her at once?

C.C. I feel that I have the responsibility to be that special person. After all, no matter what, she is the oldest among Zhang Yu's girlfriends so far.

When Euphemia heard that it would turn out, she waved to Zhang Yu and expressed her rejection.

"Ah, will that happen? Then I don't want it either."

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

"Yu, come on. I believe in you."

She has always been a swordsman in SAO, and she is the strongest female warrior in it. Now that she really has the opportunity to improve herself, she certainly will not miss this opportunity. And Zhang Yu will definitely not harm them. He dared to take out the potion and must have thought about it carefully.

Zhang Yu chuckled and looked at C.C. and Euphemia, and also gave Asuna a positive look.

"You guys don't know how powerful this perfect serum is, nor how precious it is. There is probably nothing more precious in this world than this. Let me explain it to you slowly."

Asuna was indeed the most caring person, and he couldn't help but sigh in his heart.

"After the injection of the Super Human Soldier Serum, it will stimulate the potential of the human body. It will stimulate the potential hidden deep inside the human body and transform it into a "perfect" posture of the human body. Therefore, no matter who injects the Super Human Soldier Serum, it will have a high degree of intelligence, strength, agility, acuity, and physique that ordinary people can't reach."

The best example is Captain America, but unfortunately they have never seen it. If they say this to them, it will definitely arouse their suspicion of themselves. If they know that they are just virtual tasks in the anime world, they will definitely be mentally stimulated.

Asuna and Euphemia's eyes slowly lit up after Zhang Yu's explanation. C.C. Still quietly looking at the fluorescent liquids on the table, I thought it was really beautiful.

"After the injection, ordinary people can bend the weight of 545kg without any assistance. Moreover, serum will also strengthen the human metabolic function and can completely metabolize the lactic acid and other fatigue-causing substances in the muscles, which gives the strengthened person a durability that is completely unimaginable to normal people.

Run one kilometer (26.6 meters per second) and the maximum speed can reach 48 kilometers per hour. Moreover, the enhanced human somatic cells are immune to alcohol and toxins and will not get drunk. They are also immune to most diseases, and serum also delays aging.

In other words, it can delay people's aging and enhance people's life span, and can increase their life span by at least two hundred years."
