Yes, subhumans cannot be killed.

Judging from the anime that Zhang Yu watched before, there was no intelligence at all that said how to kill the subhuman. Even if he died of old age, this method of death has not been confirmed.

Zhang Yu looked down at his thin, white palm.

"For now, I want to get power. Then there will be a price. ”

He was a little distressed, but if he didn't use it. If you die in this world, you will really lose money. Dying once is 50,000 realm coins, and that's not a joke.

Zhang Yu took out the Sumeru ring that had been covered by the aura on the Yuan Shen from the control of the Yuan Shen.

The white jade appeared directly in Zhang Yu's palm out of thin air, the ring was flawless in white jade, and the main body seemed to have a faint layer of luster. There seemed to be a trace of cool breath, which made Zhang Yu's palms slightly cold.

Zhang Yu looked at the Sumeru ring in the palm of his hand and smiled slightly.

"With you, the certainty is even greater."

He turned and walked out of the toilet and into the living room.

The house is old, just one of the many apartments that is cheap to rent.

Haidou's family is not a wealthy family, so now he just rents a house nearby to live in, so that he can go to school and study.

The living room is about four square meters in size, and there is a long table two meters long and one meter wide, which is usually used for eating. A meter in the air from the table hangs a large chandelier, which is the old-fashioned tungsten light bulb.

It was eleven o'clock in the evening, and there was dead silence everywhere.

There was only the sound of Zhang Yu's own footsteps walking around the room, and he walked to the back of the living room. He turned on the chandelier, and the pale yellow light illuminated his face so brightly that it was impossible to see what expression he had on his face at the moment.

As soon as he waved his hand, a boxy metal box appeared on the long table.

Although he doesn't have mana in his body at this moment, he can directly use the Yuan Shen to open the Sumeru Ring.

That's right, this is a medical kit that holds the perfect Super Soldier serum. Now only it can give Zhang Yu a strong power in the shortest possible time. Nothing else could help Zhang Yu much.

Because those take time to accumulate, if it is against ordinary people. Now he is enough to deal with it, even if it is the king of special forces, he is not afraid at all. But if it is a subhuman who can never be killed, and there is a black ghost comparable to the alien weapon Death, it will be a little difficult.

Zhang Yu is familiar with martial arts and martial arts, and he also has a deep knowledge of ancient martial arts. Although the internal strength and magic techniques are useless in a short period of time, with his years of aggression in martial arts and national arts, even if it is the body of Haidou, it is no problem to fight dozens of them at a time.

If you don't have physical strength in the follow-up, it will be more troublesome, otherwise you can lie down as much as you want.

Zhang Yu pressed the switch of the medical box and took out the serum medicine contained in the DNA double helix structure container.

"I didn't expect to use you again. Obviously, I've just used a few, and now I'm going to use it again, so I can only say that you're too good to use. ”

He looked at the mysterious blue liquid in his hand, crystal clear like a streamer. You can still feel the faint coolness in the palm of your hand, which is frozen in the medical box and has not yet returned to a constant temperature. He didn't feel anything last time when he was strong, but after changing his body this time, he felt like he was holding a popsicle directly.

The coldness seemed to be transmitted to the heart through the palm of the hand, and now that the potion had not been opened, the body had gradually begun to heat up. The body seems to subconsciously send out a desire for this potion.

Zhang Yu loaded the serum on the injection gun and shot it directly into his arm, leaving a hexagonal red mark like a plum blossom.

After the blue liquid was injected into Zhang Yu's body, it quickly began to decompose. Like a virus, it quickly began to infect the original cells in his body, and those original cells seemed to be slowly shrouded in a layer of blue light.

Zhang Yu could only see under the skin of his arm, and he could clearly see the blue veins bulging slightly. I could even feel the slightly chilling cold current, which was rushing to other parts of my body.

"Last time, my body didn't feel this way at all, but this time the feeling is so strong, it seems to be related to the strength of the body."

Zhang Yu looked at his arm and said indifferently.

The last time it was his own body, the first time it had undergone the initial strengthening of the system. Later, the diligent practice of martial arts reached the point of washing the scriptures and cutting the marrow, and there was also the secret of cultivating the truth and the Qingling Treasure, which was also constantly helping him to cleanse his body.

So the effect of the Super Soldier Serum is not so obvious for him.

But this time the enhancement has just been injected with super soldier serum. Zhang Yu felt the difference.

A cold current melted into his body, and he clearly sensed that his strength was slowly getting stronger. Even the magnitude of the increase is definitely not a little bit.

Zhang Yu clenched his fists, his bones clicked, and the surging power surged in his body. The sudden strengthening of his body did not make him feel intoxicated, after all, his strength was much stronger than this before.

Suddenly, Zhang Yu felt a sharp pain coming from his body.

"How... What's going on! ”

The green tendons on both sides of his forehead bulged slightly, and his brows were deeply wrinkled together. Cold sweat had begun to run down his face.

It wasn't the same as the last time he had done the serum enhancement process, but it didn't feel any pain in the process. But why did it hurt so much to change to this body?

Zhang Yu stretched out his hand to support the long table, slowly squatted down and sat cross-legged on the ground and closed his eyes. Although it was useless to run the Spiritual Treasure Technique, it could calm him down and make him forget about his pain.

The skin of his whole body began to redden, and cold sweat continued to ooze from his forehead. His clothes were all wet with cold sweat and clinging to his body.

He can still endure this pain for the time being. He was now in pain and couldn't speak normally, but the serum in his body was still rapidly strengthening his body.

The blood in the body is flowing at a high speed with the energy generated by the serum. Since the body is too weak for serum, it is strengthening the body in the fastest and roughest way.

The cells in the body are undergoing a metamorphosis, and the most obvious change is that the body seems to be inflated and begins to bulge slightly.

The muscles that didn't look strong before began to swell under the effect of serum.

Sharp pain filled his body, but his will remained strong.

Five seconds later, the pain receded like a tidal wave. If that pain was hell just now, what is left now is heavenly comfort.

Zhang Yu looked at the muscle outline on his arm, which was obviously larger. The strength, energy, nerve reaction speed, etc., have been significantly improved, and it is a large increase.

Super Soldier Serology Boosting is over.

Zhang Yu slowly opened his eyes, and the corners of his mouth turned up slightly. He now has the power to fight against subhumans, far beyond ordinary people.
