"boom!"

With a loud bang, Li Tian hit the ground on the bottom floor after seven or eight meters of free fall movement, and broke the concrete floor into a deep pit.

Li Tian looked around and found that the bottom layer was already in a mess. In this space of more than 500 square meters, several places had already caught fire. Although the flames were not very high, there was already thick smoke in the entire space at this time.

And in the thick smoke, the two figures fought together.

The thick smoke triggered the fire alarm system, and the alarm began to sound automatically. As the alarm system automatically sounded, the fire door in this space landed automatically, as if it was to completely close the fire place.

However, these fire doors have some uses for fire protection, but they seem to have no effect on the two figures fighting in the thick smoke.

"boom!"

A figure was blown out of the thick smoke and landed on an office desk beside Li Tian, ​​destroying all the desk and the office supplies on it.

The figure that was bombarded saw Li Tian, ​​and his gaze swept over Li Tian. When he saw Li Tian, ​​the figure showed a hint of surprise in his eyes of 10, but soon his gaze returned to normal. His gaze did not stop too much on Li Tian and looked at the rolling smoke again. His body was like a bolt of lightning, rushing into the rolling smoke.

Just a short look at each other, but Li Tian showed a surprised expression on his face.

"That's right, it's him! This is definitely not wrong!" Li Tian felt a sense of joy in his heart, and he kept saying to himself.

This figure gives Li Tian a feeling of a level nine zombie.

And the moment the figure looked at Li Tian, ​​the nine-colored corpse lotus in Li Tian's heart automatically released some transparent silk threads and poured into the figure's mind.

Through these transparent silk threads, Li Tian's judgment was also confirmed. This guy was a zombie, and at least he had a corpse crystal in his mind.

However, this guy's appearance does not have the zombie characteristics at all. From the outside, he is no different from humans. Even when he is angry and fighting, his zombie attributes are not revealed at all.

There is only one explanation for this situation, that is, this guy is no longer a zombie. Maybe he was a zombie, but now he has basically escaped from the attributes of zombies, and his powerful combat power during the zombie period has been well preserved.

This should be the research result of this secret institute.

Li Tian knew that any new drug needs to have an action after its birth, called clinical trials. Li Tian guessed that the reason why this zombie had such changes may be the result of clinical trials.

The result of Li Tian’s guess is almost the same as the actual situation.

It turned out that in the second year of the End of the World, this secret research institute, led by Kuroto Otsuka, had made some progress in research on zombie viruses.

However, at that time, all the research results were based on theory, and the low-level zombies caught by the Zombie Research Institute had been consumed in the past year's research process, and there were no more zombies in the entire institute that could be used for their experiments.

There is only one way before them, and that is to use their own bodies as test subjects.

This requires a great spirit of self-sacrifice.

These crazy researchers no longer care about so much. In order to help the entire human being get rid of the zombie virus as soon as possible, these researchers have chosen to sacrifice themselves one after another.

The first choice to sacrifice were the soldiers of this secret institute. They injected zombie viruses into low-level zombies in just a few days, and then treated them by injecting zombie virus antidotes.

However, the first research result was not successful. The antidote to the zombie virus did not completely eliminate the loss of the virus, and the guardian soldiers became zombie-like existences.

They were the zombies that were killed by the ninja in the tunnel.

After these soldiers, the secret institute further improved the antidote of the zombie virus. The grassroots scientific researchers in the institute were the grassroots scientific researchers in the institute. However, this improvement only made the antidote of the zombie virus more effective, and did not completely eliminate the zombie virus, and these scientific researchers eventually became the zombie on the top layer.

However, although these zombies after the antidote of the zombie virus are very low, they have basically recovered their human consciousness, and even some of their physical functions are the same as those of humans.

At that time, there were only four or five humans left in the entire institute, among which were the Otsuka Kuraki. The Otsuka Madman was entrusted by everyone and returned to the village where the children lived and visited the children.

Otsuka Kuroto alone told Otsuka General the research situation in the entire research institute and told Otsuka General that if he could come back in three months, it means that their zombie virus antidote had been developed successfully. If he did not come back in three months, then let Otsuka General take care of the children.

Before leaving the village, the Kuroto Otsuka also handed over a tube of injectable zombie antidote to Otsuka, and told Otsuka that if normal humans injected this reagent, they could be completely immune to the zombie virus.

"Hahaha, you are no match for me! Now the study is full of smoke and flames. If you continue to get entangled like this, your son Otsuka will die due to poor breathing. I believe this is definitely not what you are willing to see too much!"

"So, I advise you to surrender and hand over the antidote of the zombie virus you are guarding. At that time, I can guarantee that you father and son are safe and sound, and also ensure that you father and son will become heroes of the Japanese island country!" The ninja said with a sneer.

It can be seen that although the ninja's legs were a little staggering, his strength was still very strong. The ninth-level zombie was no match for the ninja at all.

"Impossible! Even if we both die here, we will never hand over the antidote of the zombie virus that we exchanged for with our lives to you!" the ninth-level zombie roared.

"Play!"

"Play!"
