"Huh, an evolutionary tentacle suddenly lost contact, could it be said that it was damaged?"

"It's kind of interesting, it's only been seven days since the evolution process started, and someone can destroy the evolutionary tentacles, so it seems necessary to continue to increase the difficulty. ”

"Then on the fifteenth day, it's good to release the E-class evolution beast, but in this way, isn't it too difficult to increase? A careless person could completely wipe out all intelligent life on this planet. ”

"No matter, anyway, this is just a low-level life resource star, it should be an experiment, if the experiment fails, it's a big deal to find a higher-level life resource star!"

In the deepest part of the core, the mysterious evil eyeball whispered softly, a little surprised, but it soon disregarded and turned its attention to the next experiment.

As it said, it doesn't matter if a low-level life resource star is an experiment, and before you know it, the difficulty of its experiment is constantly rising, and it has reached an extremely terrifying level.

According to the Pan-Universe Joint Covenant, the danger factor of that mysterious evil eyeball has far exceeded that of the SSS level, and it is definitely the first object to be exterminated, but due to various inconsistencies, that mysterious evil eyeball is hidden in the extremely remote earth, and it has never been noticed at all, and there is nothing that can threaten it.

In this way, the mysterious evil eyeball can naturally do all kinds of experiments unscrupulously.

......

S City, Civic Square.

Zhang Yu didn't know that because of his momentary curiosity, he inadvertently triggered a new round of disasters on the earth......

At this moment, Zhang Yu's attention was on the ball of light in his body that flashed with demonic blood-colored light.

Zhang Yu looked around, and after finding that there was no abnormal movement, his mind moved, and he directly entered the dream space of the Demon Mind Butterfly in the form of a spiritual mind body.

Sure enough, just as he thought, the demonic blood-colored ball of light that the Demon Mind Butterfly had drawn out of his hand was quietly floating in midair.

"What is this, why did it stimulate the Demon Mind Butterfly to take the initiative to seize it?" A flash of curiosity flashed in Zhang Yu's eyes, and he took the demonic blood-colored ball of light in his hand, and carefully probed it, and found that it was neither a blood crystal, nor an evolution liquid, and it could not really absorb and fuse.

"Could it be that it is used to strengthen the soldiers?" Fu Zhi's heart, Zhang Yu suddenly thought of a possibility, and with a movement of his mind, he directly got the flame war knife into the dream space.

Zhang Yu guessed correctly, the demon alien blood-colored light ball was used to strengthen the soldiers, and he saw that after touching the flame battle knife, the demon alien blood-colored light ball suddenly shattered, turning into countless demonic blood-colored light spots, and submerged into the knife body of the flame war knife.

The next moment, the flame war knife in Zhang Yu's hand was red, and there was a change, compared to the initial form, the flame war knife at this moment was blood red all over, becoming more and more sharp, and the flames that were originally unstable on the knife surface were also restrained, turning into flame runes, which were engraved on the back of the knife.

"The Warrior has evolved?!" Zhang Yu's face was full of surprise, you must know that the Warrior Seed is very rare, and it is already very lucky to be able to obtain a Warrior Seed, let alone evolve again.

In his previous life, Zhang Yu had also heard that soldiers seemed to be able to evolve, but the secret method of how to evolve was only in the hands of a very small number of top-level powerhouses, and he had no way of knowing the miserable mixture.

But in this life, Zhang Yu not only knew the secret method of soldier evolution, but he could also be sure that the secret method of soldier evolution that he had mastered could not be replicated, and only he could use it, because other people did not have the Demon Butterfly at all, and naturally they could not absorb the soldier evolution energy contained in that strange blood-colored tentacle.

In addition, as far as he knew, although the very few top-level powerhouses in his previous life had mastered the secret method of the evolution of soldiers, they often ended in failure, and it seemed that the conditions reached were extremely difficult, and on his side, with the Butterfly of Demon Thoughts in hand, he only needed to search for those blood-colored towering giant trees that had not completely withered in the future, and he could get more warrior evolution energy, which was obviously much easier, and he didn't know it.

The more Zhang Yu thought about it, the more excited he became, but he didn't stay in the dream space for long, after evolving and upgrading the flame battle knife, he immediately returned to the real world, after all, there was no one around him to guard, if someone or a mutant monster raided, it would be dangerous.

Holding the evolved flame battle knife, Zhang Yu swung and slashed a few times, but he was still not satisfied, and ran directly towards a nearby residential area.

"Roar!!

After approaching, a hideous mutant wolf dog roared angrily, opened its bloody mouth, and rushed towards Zhang Yu quickly.

"It's a good time!" Zhang Yu laughed, holding the evolved flame battle knife and fighting fiercely with the hideous mutant wolf dog, with his current strength, it was really easy to kill a red crystal fifth-order mutant wolf dog, but Zhang Yu did not stimulate his demonic evil ability, but deliberately passed the actual combat test of the evolved flame war knife.

The final test results made Zhang Yu very satisfied, the evolved flame war knife was extremely sharp, and the lethality was very amazing, and the mutant wolf dog was cut into two pieces with a random knife, and this was still without enchantment, if it was enchanted through the secret method, the lethality of the flame war knife would become more and more terrifying.

Although with his current strength realm of the third order of amethyst, even the fifth-order red crystal has no strengthening effect, but the operation of the dream space of the Demon Butterfly requires a large amount of blood crystal energy, as the so-called accumulation of small amounts adds up, even the lowest primary red crystal, Zhang Yu does not want to let go.

Zhang Yu knew very well in his heart that now was just the beginning, and the mutant monsters he encountered in the future would definitely become more and more terrifying and powerful, and if he wanted to manifest himself in the dream space, the blood crystal energy required would only increase, and while he had time now, Zhang Yu only wanted to hunt as many blood crystals as possible in order to prepare for the critical moment in the future.

Zhang Yu was very crazy, walking through the residential area alone, facing the siege of a large number of mutant monsters, setting off waves of bloody killings, until night fell, he did not stop.

"Calculate the time, Huazi and their side of the battle should also come to an end, I don't know what the outcome of the battle will be?" Zhang Yu found a bathroom that was still usable, washed off the blood stains on his body, and walked outside.

By the time Zhang Chengzhong and the four of them rushed over to meet, Zhang Yu had already lit a bonfire in the center of the civic square, and roasted a thick mutant wolf dog's thigh to the point of oil.
