This is not the end, as far as the excitement comes, Zhang Yu shook his arm and punched out, and it was very easy to smash a heavy corridor wall, and the inner edge of the cave was pitch black, and at a glance, he knew that he had suffered an extremely terrifying high temperature burn.

"Boss Yu, this is your ability, so powerful!" Seeing this, Zhang Chengzhong and the others immediately reacted, and their faces were full of shock.

All along, they were very strange, and they didn't understand why Zhang Yu had been slow to activate the ability, but now after witnessing the terrifying power of Zhang Yu's ability, they suddenly understood a little.

"Vaillant is really good. The corners of Zhang Yu's mouth curled slightly, and after trying his hand, he was very satisfied with the power of demonic power.

First of all, after activating the demonic evil energy, his entire right arm became extremely thick, and his strength doubled on the original basis, not to mention a thick wall, even those tank ants with strong defense, Zhang Yu was confident that he would blow them up with one punch.

Secondly, it is those purple ** fires, after the experiment just now, the power is very amazing, and it is easy to burn the body of the mutant rat king to ashes, compared to it, the corrosive flame on the flame war knife is a little weak, and it has slashed the mutant rat king many times in the previous battle, but basically did not cause any substantial flame damage.

Finally, and most importantly, unlike Zou Yitian's Thunder Fist, which needs to gather energy, and Li Xunhuan's Xiao Li Flying Knife can only condense twenty flying knives at a time, etc., his demonic evil energy has no obvious shortcomings, as long as his arm is still there, as long as the person is still alive, he can always use it.

The dual power attribute has no obvious shortcomings, which once again proves how correct the idea of the genius madman in the previous life was, but unfortunately the difficulty is too great, and no one can achieve it in the end, but it is cheaper to pass through the rebirth of Zhang Yu.

"Take a break in place, it's safe here, and when we're done, we'll clean up the sixth floor!" Zhang Yu said after a slight sigh.

The mutant rat king was very domineering, occupying the fifth floor of the entire dormitory building, and the other mutant rats did not dare to enter this floor at all, so it gave Zhang Yu and the others an excellent rest space, even safer than the Wenyuan restaurant.

"For the first time, I felt that the bed in the dormitory was so comfortable!" Xiao Hua and the others also realized this, their eyes were shining, and they all found a dormitory bed to lie on, you must know that although there is no shortage of food in the Wenyuan restaurant, the sleeping conditions are very ordinary, they are all patched together with tables, far less comfortable than the beds in the dormitory.

Including Zhang Yu, everyone slept a peaceful nap, and after waking up, they couldn't help but feel refreshed, and the fatigue accumulated in the previous few days was also swept away.

"If I can eat a full meal again, it will be even more beautiful!" Zhang Chengzhong touched his somewhat shriveled belly and said.

"After cleaning up the sixth floor of the dormitory building, it won't take much time to eat in the Wenyuan restaurant. A faint look of confidence flashed in Zhang Yu's eyes, and he proved it with practical actions.

Coming to the sixth floor of the dormitory, Zhang Yu directly stimulated the demonic evil energy, rushed forward, and rushed to where there were many mutant mice, and the terrifying purple ** fire rose and burned, burning one mutant rat after another to ashes.

Those mutant rats fought back frantically and attacked Zhang Yu from all directions, but with the experience of fighting with the mutant rat king, the speed of these ordinary mutant rats was really a little unsightly, not to mention that after breaking through and advancing to the fifth order of red crystal, Zhang Yu's neural reaction speed was also greatly improved, and he could easily capture the whereabouts of those mutant rats.

"Boss Yu, he was already perverted enough before he activated his ability, but now he is even more perverted!" Zhang Chengzhong exclaimed, and then joined the battle group with a laugh, and saw that he was covered with a layer of materialized tortoise shell, and then a blood-red energy light shield appeared, even if he stood there and did not move, those ordinary mutant rats could not break his defense.

"Whoosh !!"

Under Zhang Yu's stimulation, the arrogant Li Xunhuan also shot wildly, throwing out one flying knife after another, wanting to chase Zhang Yu and break through to the fifth order of red crystal as soon as possible.

Xiao Hua and Kite Xiaobei are also fighting, in the previous battle with the mutant rat king, the two of them had almost no contribution, they both held back their strength, and wanted to perform well, and under Zhang Yu's leadership, the strategic resource allocation method of their team has been very clear, that is, according to the specific combat contribution to distribute, if they keep playing soy sauce, they will soon be pulled apart, and then kicked out of the team, and that is definitely not what they want.

As Zhang Yu expected, the battle ended quickly, and in less than an hour, everyone completely cleaned up the entire sixth floor of the dormitory building, and hunted and killed more than 300 mutant rats and hundreds of mutant cockroaches.

Back at Wenyuan Restaurant, after eating, Zhang Yu first distributed the spoils of this battle according to everyone's specific combat contributions, and then took his own share, came to a quiet corner, and "meditated" again.

For Zhang Yu's strange behavior, everyone has long been surprised, and every time at this time, they have a tacit understanding to keep quiet, so as not to disturb Zhang Yu.

"It's dangerous!"

In the dream space of the Demon Butterfly, after carefully watching the entire battle process through the battlefield retrospection, Zhang Yu couldn't help but secretly say that he was lucky, from the perspective of God, he found that he was almost succeeded by the mutant rat king several times, and it can only be said that winning this battle is really thrilling enough, and there is no lack of luck in it.

However, luck is sometimes part of strength, and after summarizing and learning the lessons of the battle, Zhang Yu did not hesitate to consume blood crystal energy to manifest the terrifying mutant rat king.

"Bang Bang Bang !!"

In the dream space of the Demon Butterfly, Zhang Yu started a new round of battle with the mutant rat king, and this time it was a real heads-up.

Although the chance of encountering other mutant rat kings in the future is very small, the mutant rat king is undoubtedly a good target to fight, and after stimulating the demonic evil energy, he just used it to practice his hands.

When he first came up, Zhang Yu was abused very badly by the mutant rat king and died one after another, but as Zhang Yu became more and more proficient in the control of demonic powers, he gradually narrowed his disadvantages, and began to have back and forth with the mutant rat king, and even gained a certain upper hand.

It wasn't until the Blood Crystal Energy absorbed by the Demon Mind Butterfly was exhausted that Zhang Yu returned to the real world without getting enough of it.

At this time, a loud radio horn sounded in the sky above the campus.
