In addition to heart therapy, Su Chen's physical strength has also been strengthened from the third degree to the fourth degree of strengthening.

The fourth-degree enhancement was not a small number, it represented that Su Chen's physical strength was already able to ignore the claws of the first-level mutant creatures.

Although it is not as good as soft armor, let alone war armor, the growth of physical strength has increased Su Chen's survival rate and performance.

The only thing that gave Su Chen a headache for this promotion was the conditions needed for the next promotion.

To advance to a seventh-level evolutionary, Su Chen needed to kill six different types of sixth-level mutant creatures.

If that's the case, it's no different from before, but this time in addition to this condition, there are more probabilities.

Su Chen has personally experienced 80% of the cases where he failed to advance, and at first glance, the probability is only between 50% and 80%, Su Chen thinks that with his luck, I am afraid that ten times is too little.

Advancing to the seventh level of evolution, not only fused the previous two promotion conditions, but also increased some difficulty, after all, the probability of failure in the past would increase every time, and this time it was random.

For the condition of randomness, Su Chen has the most headache.

Fortunately, this promotion was successful, there is a lot of good news, Su Chen doesn't care about the conditions needed for the next promotion for the time being, after all, by the next promotion, he needs to accumulate at least 20,000 points of experience, which will take too much time.

It is worth mentioning that after Su Chen was promoted to a sixth-level evolutionary, there was no collective mutation of mutated creatures in the entire Nanshi, which meant that there were no sixth-level mutated creatures in Nanshi for the time being, and Su Chen could look for fifth-level mutant creatures with peace of mind and treat Xiaobai.

With level suppression, there will be strength suppression, and the battle will become extremely easy.

After the successful promotion, Su Chen's body fatigue and tiredness were swept away, Su Chen's consciousness moved slightly, and he found that his perception range had doubled, and his vision, hearing, and other aspects had been enhanced.

After learning all this, Su Chen didn't stay in the house for long, he jumped from the window in a few steps, and hurried to Ye Yao's battlefield to spread the good news.

Not long ago, just as Su Chen was about to advance, I don't know if it was Ye Yao's bad luck or the other party's ambush, Xiao Bai and Ye Yao were attacked by fifth-level mutant creatures.

If it weren't for Xiaobai's quick reaction and blocking its attack for Ye Yao, Ye Yao would have been seriously injured if he didn't die at this moment.

Attacking Ye Yao was a fifth-level Dalmatian, its whole body was grayish-white, hairless, and its skin was covered with red spots, looking like a creature about to decay.

When Su Chen arrived, Xiao Bai and it were already fighting together.

Ye Yao's perception was keen, and he sensed Su Chen from afar.

Before Su Chen arrived, Ye Yao noticed that Su Chen had changed significantly from not long ago.

Su Chen's aura was no longer the kind of looming and difficult to see, but a killing aura with killing.

As soon as her perception came into contact with Su Chen, the killing (killing) aura came to her face, rushing straight to her heart, making her dare not even take a breath of air.

Ye Yao has a keen perception and can sense a lot more than ordinary immune people, because of this, she perceives more intuitively, but more resistant.

This is not that Su Chen deliberately showed it to Ye Yao, but that Ye Yao deliberately used his perception to check Su Chen.

Fortunately, Su Chen did not deliberately show his killing aura, otherwise this would be a heavy injury to Ye Yao, who had a keen sense.

The more perceptual a creature is, the more vulnerable it is to being harmed by the killing qi, and a perceptual immunizer like Ye Yao, if he is not at the same level as Su Chen, is enough to be hit hard.

"Succeeded?!" Ye Yao said.

"Well, with a 100% success rate, it's hard to succeed even if you don't want to." Su Chen rushed to Ye Yao's side and said with a light smile.

"Don't say so much about it, Xiaobai can't support it anymore." Ye Yao didn't chat with him, and hurriedly said.

"Xiaobai, it lacks experience, it is necessary to let it experience it, if it is all up to me, then sooner or later it will die at the hands of other creatures." Su Chen didn't go to help, and said lightly.

While Su Chen was speaking, Xiao Bai's voice sounded in Su Chen's consciousness.

Xiao Bai's battle was very fierce, but he was able to find time to communicate with Su Chen.

Its meaning is very simple, let Su Chen not make a move, this is a battle that belongs to it, and it is also its prey, and it should be hunted by it.

Hearing Su Chen's words, Ye Yao thought about it and felt reasonable, so she didn't say more.

Seeing that Su Chen didn't react, Xiao Bai knew that Su Chen acquiesced, and he no longer had any distractions at the moment, and focused all his attention on the mutant dalmatian.

The strength of the mutant dalmatine dog is not weak, it is a top mutant creature that is about to become a sixth-level mutant creature, and its combat power is not comparable to that of ordinary fifth-level mutant creatures.

However, it mutates so quickly, and the price is that it doesn't have a few skills that it can look at, which makes it difficult to greatly increase its base power, and only a small increase is not enough to defeat creatures of the same level with a crushing advantage.

Xiaobai is not an ordinary level 5 mutant creature, and although it requires a lot of experience bars, this does not mean that its combat power is restricted.

The experience bar is only an inevitable need for Xiaobai to change again, and it has nothing to do with the growth of Xiaobai's combat power.

With Xiao Bai's current combat power, he is not the top fifth-level mutant creature, but he has been able to reach the upstream level, and with Xiao Xiaobai and atomization, Xiao Bai can barely fight with it.

Although Xiaobai is lazy on weekdays, once he fights with creatures of the same level, he will definitely go all out.

Mutant creatures like mutated Dalmatians are exactly the opponents that Xiaobai has always wanted.

The perception of the mutant dalmatians is not bad, and as soon as Su Chen appeared in its perception, it noticed it for the first time.

Su Chen's body exuded a killing aura, unlike the aura that was extremely difficult to detect before.

It's not that Su Chen can't transform, it's that Su Chen didn't deliberately suppress his breath, so that his most primitive aura was shown to the mutant dalmatian.

Just the breath made the mutant dalmatian want to retreat, and it was able to clearly affirm that it was not Su Chen's opponent.

However, Xiaobai and Xiaobai were entangled with it, and the mutant Dalmatians had no intention of fighting, but they had to fight with Xiaobai, which made its combat effectiveness shrink a lot.

Even if Su Chen didn't make a move, his appearance not only boosted Xiaobai's morale, but also lowered the morale of the mutant Dalmatian, I have to say that the existence of the strong does have a suppressive effect on the weak.

When Xiaobai was fighting with all his might, Su Chen didn't care about its battle, but chatted with Ye Yao on the side.

Su Chen now has the skill of heart healing, he is not afraid of Xiao Bai being injured, if such an opponent needs him to help or deter, then Xiao Bai will never be able to break through.

Ye Yao saw that Su Chen was indifferent, knowing that Su Chen had his thoughts, she trusted him, didn't care about this, and talked to Su Chen about today's events.

Xiao Bai did not disappoint Su Chen, and after fighting hard for ten minutes, he bit off the head of the mutant Dalmatian dog, and then bit it and ate it all.

In normal times, Xiaobai will bite the body of the prey, but for some reason, maybe Xiaobai feels that its skin is poisonous, and throws its body aside in disgust.

After a battle, Xiaobai was scarred, but they were all minor injuries, and he could recover after a short rest.

These injuries are not enough for Su Chen to help recover, just like experience potion, if you can, you don't need it, and there is definitely no harm in letting your body recover on its own.

Xiaobai and Su Chen have the same consciousness, and they have heard about the heart therapy in the conversation between Su Chen and Ye Yao, but it didn't speak, not because it didn't know how to speak, but because its thoughts were the same as Su Chen's, and it didn't want to rely on external forces to hinder its own growth.

After Xiaobai's battle, Ye Yao faintly felt that he had signs of a breakthrough, and he didn't know if it was because of the death of the fifth-level mutant dalmatian, or some other reason.

Hearing the news that Ye Yao was about to be promoted, Su Chen was naturally happy, the two of them came to a safe empty house on the side, Xiaobai lay down to rest, Ye Yao was quietly promoted, and Su Chen was guarding on the side.

Ye Yao only sensed that there were signs of a breakthrough, and there was still some time before she was promoted, so Su Chen was not in a hurry, she brought a sofa and watched quietly.

At Su Chen's feet, the scarred Xiaobai had no intention of sleeping, it stared at Ye Yao with its eyes, and seemed to have some thoughts about her promotion.

Since Su Chen was promoted to a sixth-level evolutionary, he found that a fifth-level evolutionary was just the threshold for becoming a survivor, and he still had a long way to go in the future, and in the future one year later, a strong person like him would probably have to be called a weak person at that time.

If it really develops as Su Chen thought, then ordinary people without the protection of the strong will only have a dead end.

After all, the immunizers are only a minority, and the evolutionaries are even more out of the immunizers.

Not all immunizers have the possibility of advancing to level six, and the vast majority of immunizers will be trapped at the level of level five immunizers, some of them do not understand the conditions for advancing to evolvers, and some do not have this talent.

There are very few survivors who can become an evolutionary before the sixth level, as far as Su Chen knows, except for him, it is also like this for Pikadi.

Su Chen looked at Ye Yao quietly, he vaguely felt that Ye Yao would be the next fifth-level evolutionary, although she only had the special skill of soul building blocks, and her talent was not the top.

But Ye Yao's luck has always been very good, and he has reason to believe that Ye Yao can become the next fifth-level evolutionary.

Once Ye Yao successfully advanced to the rank five evolutionary, then her future will pave a long road, and the road she can walk will be as far as Su Chen, and there will be no situation where Su Chen has been making progress and she has stopped moving.

Come to think of it, the first time Ye Yao groped for perception and the first time he advanced, he was all helped by Su Chen, but now it was different, even Su Chen, who was a sixth-level evolutionary, would have difficulty invading Ye Yao's consciousness as a fourth-level immunist.

He could only watch quietly from the sidelines, and he was completely incapable of helping.

Even if Su Chen had the ability to help, Ye Yao didn't need him to help.

Su Chen, as well as the people close to Su Chen, rely on themselves for their growth, and they don't want to use external forces to improve their own strength, Su Chen's closest Ye Yao, Xiaobai, Xiao Ash, and Ye Xin are all like this.

Even this group of managers in Dragon City is like this.

With the help of external forces, it can only help for a while, not for a lifetime.

In this apocalyptic world, the world of mutated creatures, if you don't become stronger, all that awaits you is destruction.
