At the same time, the leader, who was constantly consolidating with other bases, used the method of cooperating with large clusters, merging medium-sized ones, and annexing small ones.

And in this way, they developed rapidly, and gradually formed a very large gathering place, and faintly became a force.

They gave themselves the custom name Falcon because they wanted to soar freely in the sky like an eagle.

Although in the end, the hand that put forward this opinion did not become the general leader of the entire new situational force, but because of his certain contributions, he also had a certain position in the whole force.

And this city implements the original direction and goal, and deals with monsters in the form of guerrilla warfare, and never confronts monsters.

And it turns out that this practice did indeed save their lives in subsequent practice.

Over time, the monster eventually appeared to reach

The monster of the secondary mutation, well, but when the secondary mutated monster first appeared at that time, it became a nightmare for all the people in the gathering place.

Because this kind of monster, if it is a secondary mutant monster with deep armor, then they will find that all weapons cannot cause effective damage to this secondary mutated monster, and even after fighting for a long time, it only cracks the monster's shell a little, and does not cause any physical damage to the entire monster.

In the face of speed-type secondary mutant monsters, they can't aim and hit at all, but as long as they form a firepower network, no matter how fast they are, they can still be contained and suppressed.

However, in the face of heavy secondary mutated monsters, there is no way, because their attack cannot cause any substantial damage, which leads to the fact that once these secondary mutated monsters appear outside the gathering place, the medium-sized gathering place has basically predicted the destruction in advance, and must be prepared to evacuate in advance.

But in fact, when you are attacked by monsters, even if you are prepared in advance to break through to one side, in the face of monsters everywhere outside, you can't escape at all, and most of the lucky people meet the falcon in the end and become one of them, but those who are unfortunate end up dying outside the wilderness, and there is no one to store the bones.

At that time, in fact, all the people did not destroy the corpses that were killed or injured by the monsters, and most of them were not aware of these problems, in fact, because most of them were actually in a situation of fleeing or evading, and when they were unable to protect themselves, how could they have other energy to take care of these?

And in fact, there were not many monsters that they originally had, but as they continued to injure and infect other people, it eventually led to more and more monsters, and at the same time, the defense became more and more difficult, and it really became that everyone began to consciously raise this habit, in fact, it had begun to mutate once.

Because at this time, they realized that these monsters devoured the bodies of their own kind and fought with them, so that they could evolve themselves.

At this time, in fact, Dr. Mad also faintly proposed an experiment with the high-level, that is, let people with resistance genes eat people, and when the energy reaches a certain level, maybe a mutated human can be produced.

But because the whole plan and demand were too cruel to both the top and the people at the time, this proposal was rejected as soon as it was put forward.

As time goes on, there are more and more monsters, and they are getting more and more powerful, and the appearance of secondary mutant monsters is a huge blow to the gathering place or the national army or the forces.

Because they don't have any ability to directly kill the monsters of the secondary mutation, their weapons cannot cause effective damage to the heavy armor units of the secondary mutation, so all the defense lines can only retreat.

At this time, the mad doctor proposed his second experiment, which required human dissection or extreme cruelty, and at the same time reacted the monster's virus with resistant atoms, which was equivalent to making a person feel alive, the pain of being swallowed by the virus little by little, and also documenting.

And all decision-making levels are facing great pressure, because whether it is the army or the people, there are more and more doubts about high-level decision-making levels.

Out of helplessness, I finally agreed to Dr. Madman's plan, and after the selection of 50,000 people, the final experimental subjects had a total of 5 research subjects, and finally 1 person died, although it was said to be dead, but in fact he was still alive, but although he was still alive, but the whole person had gone crazy and became a person who was not a ghost or a ghost, but fortunately, the experiment was successful in the end.

Because of this experiment, blood energy was finally discovered, that is, the energy hidden in the markings on those bodies, and this energy can cause an effective blow to the virus, perhaps because it is homologous, this energy is like a virus, which can devour other viruses and then destroy them.

In fact, the main reason for the high-level to agree to this experiment is that only this mad doctor had made a statement before, which made them pay attention to those people with markings on their bodies, and after these people entered the army and underwent a certain amount of training, most of them quickly became mutated people.

And these people have become the middle force in the face of a mutated monster, and in the face of a secondary mutated monster, they often need to be attacked by a group attack by those who mutate in turn to be able to suppress them.

However, the number of people they can achieve a mutation is limited after all, and they don't have the ability to kill the secondary mutated monsters, the most they can do is pay a heavy price to beat the secondary mutated monsters back.

Otherwise, most of the area would have already become a paradise for monsters, and there would not be the current situation that would at least be embarrassing.

The experiment was successful, and 4 people who had reached the secondary mutation for the first time were born, and although this experiment was successful, it became something that others kept silent.

Because both those who heard and experienced it, the moment all the data came out, they were shocked by this terrible experiment, which recorded not only the casualties, but also some of the behaviors and thoughts they had done.

And the reason why these are recorded, according to Dr. Madman, is to better record, better observe, and meet the conditions for secondary mutation, after all, the primary mutation to the secondary mutation is not only the cause of energy, but also other reasons, which will contribute to the secondary mutation.
