Retracting the automatic rifle, the long knife reappeared in Yun Ye's hand, with a clear roar, a gust of wind, Yun Yewu disappeared in place, and when he reappeared, he had already come to the remaining mutant rats.

The tip of the knife hung upside down, like a sharp blade falling from the sky, piercing its inverted triangular head under the terrified gaze of the mutant rat, and as its fat body twitched violently, it was completely silent.

Killing this mutant rat, without the slightest hesitation, Yun Ye swung his knife out again, and where the blade was swung, a mutant rat screamed and pounced.

This mutant rat originally wanted to take advantage of Yun Ye's killing of its companion and had no time to be distracted, so it wanted to sneak up on him, stabbing its sharp claws into the head of the prey in front of him in one fell swoop, and then enjoy this hard-won hearty meal.

The ideal is very plump, but the reality is very skinny, and if the rest of the people come, I am afraid that they will fall into the way of this mutant rat.

It's a pity that its opponent is Yun Ye.

A pervert with perceptual skills, who can anticipate all dangers in advance and has a very strong strength.

Almost at the moment of the mutant rat's action, the perception skill alerted Yun Ye, and Yun Ye instantly decided to take the plan.

Hunter and prey, the identity change is often in an instant.

And once that moment comes, it means that one of the two will die.

Just like now, Yun Ye's arms seemed to be waving at random, but the sharp blade suddenly appeared on the path of the sneak attack on the mutant rat.

The sneak attack mutant rat knew that Yun Ye's actions were agile, so he also burst out with all his speed, wanting to kill Yun Ye in one fell swoop.

But it was precisely because it had riveted enough strength to rush up to kill that it looked as if it had voluntarily bumped into Yun Ye's sharp blade.

Then, the next scene is more bloody, with skulls shattered and red and white objects squirting out first.

"Kill a level 5 mutant and gain 20 XP."

Listening to the sound coming from the system, Yun Ye suddenly realized that it was a level 5 mutant rat, no wonder he knew how to use the form of the field to sneak attack without the control of the level 6 mutant rat.

Thinking of the level 6 mutant rat, Yun Ye was stunned, because he looked around and didn't find the dark red figure.

Secretly said no, the mutant rat seemed to be smeared with oil on the soles of his feet as soon as he saw that the situation was wrong.

It seems that it is necessary to catch the mutant rat, otherwise it will be a problem in the future.

Once the mutants have a mind, it means that they have evolved towards intelligent beings.

They no longer rely on instinct to rush and kill, but know how to cooperate, or know how to build their own "army" like the mutant rat.

At that time, they will transform into real hunters, baring their fangs and wielding butcher knives at the remaining prey.

Yun Ye, who had made a decision, decided not to continue to waste time here, his body continued to rush and kill, and he killed the few remaining mutant rats that could still move, and glanced at those mutant rats that could not move, Yun Ye pondered for a while, and decided to solve this place first.

The level 6 mutant rat was hit hard for some reason, and it shouldn't have been able to run far, and leaving these still alive mutant rats here like this is an unstable factor after all.

When he walked in front of those mutant rats with claws shattered or broken calves, although those mutant rats were unable to move, they still bared their teeth and looked like they wanted to eat Yun Ye.

Without the slightest mercy, Yun Ye took the roll call one by one, constantly black knives in, red knives out, just a few minutes, and only a bunch of corpses were left in place.

After looking around and finding that there were no fish that had slipped through the net, Yun Ye began to prepare to find the trace of the level 6 mutant.

When I came to the place where the level 6 mutant rat was struggling in agony, I found a pool of scarlet blood stains in the same place.

That mutant rat was injured?

Yun Ye's expression was slightly stunned, because of the color of the mutant rat's hair, coupled with the constant beating of the firelight, Yun Ye had not noticed that the level 6 mutant rat was injured before.

In other words, which of the mutant rats in here dares to hurt it?

Judging from the previous performance of those mutant rats, it didn't look like they dared to challenge that level 6 mutant rat.

Could it be yesterday's "man-rat war"?

Yun Ye once again denied the idea in his heart, it can be seen from the fact that the level 6 mutant rat did not participate in the siege before and smeared oil on the soles of his feet when he saw that the situation was not good, that level 6 mutant rat was very cunning and very careful to spare his life, and at a glance, he knew that it would never be able to go into battle in person in that situation yesterday, and it must be the same as before, sitting on the side to watch the show.

If not, who would it be?

Yun Ye frowned slightly, and thought of the blurred figure on the ceiling that he had glimpsed when he first came to the underground garage.

Could it be it?

Yun Ye glanced up at the empty ceiling, yesterday because his vision was too dim, and the thing was too agile, Yun Ye couldn't see his figure clearly, which caused him to not have time to activate the visitation skill.

So what level that thing is, Yun Ye still doesn't know.

Even the level 6 mutant rat under the protection of many mutant rats can be injured, and its strength and level are so strong?

Yun Ye felt that the greater danger might still come from the unknown thing on the ceiling.

Alas, another big trouble.

Yun Ye sighed lightly, the level 6 mutant rat had not yet been solved, and now another mutant might be much stronger than the level 6 mutant rat had emerged.

Ma Dan, are all those mutant upgrades rockets? How can one run faster than the other?

Thinking that he had the Hongmeng system, he still couldn't compare to the upgrade speed of those mutants, Yun Ye was a little frustrated for a while.

"I said Xiaoyunzi, are you still going to end it day by day? With such a large base of mutants, coupled with the fact that they devour each other and other reasons to upgrade and evolve, shouldn't the mutants level up faster in the first month or two? When you get to the back, the upgrade speed of the mutants has gradually stabilized, and that is when you exert your strength, and now you, the first task is to ensure that the strength and level are not dragged too far by them, otherwise you will not be able to catch up in the future. ”

"You just keep killing those mutants now, everything is in my gray old man and the system." The gray boss opened his mouth with a grin, and said in a tone that I was not surprised.

In this regard, Yun Ye just rolled his eyes and said disdainfully, "Of course I don't have to worry about the system, but what ......about you?"

Although he didn't finish speaking, the thick distrust in his tone couldn't be concealed.

"......" The gray old man choked speechlessly, and for a moment he felt offended.

Yun Ye smiled and shook his head, although he didn't believe it, but in his heart, he had long regarded Gray Lao as an indispensable part of his own growth, without Gray Lao's enlightenment and education, Yun Ye would not have been able to get such a strong strength now.

Of course, the gray old man also knew what Yun Ye was thinking in his heart, the reason why one person and one fog were fighting so much was just to ease Yun Ye's more dignified mood.

After checking the bloodstains, Yun Ye slowly walked in a certain direction of the underground garage along the dripping bloodstains.

Fortunately, the current firelight was relatively bright, so it was not very difficult for Yun Ye to observe the blood stains dripping from the mutant rats, and soon he followed the blood stains to a fireproof door.

Open the fire door, and inside is a stairwell that goes up.

Did it run to the ground?

Yun Ye glanced at the dark stairwell, and after groaning for a while, he decided to follow and take a look.

That mutant rat must be eliminated today, whether it's for future safety or for upgrades.

As soon as he entered the stairwell, Yun Ye's eyes were dark, he couldn't see anything, he didn't panic, he slowly touched the guardrail, and climbed up along the guardrail.

"Click...... Click...... Click......"

The sound that is usually not loud is indeed unusually clear in this closed stairwell, Yun Ye walked up the guardrail, and at the same time he was still counting silently in his heart, "3, 4, 5, 6, 7......"

Suddenly, Yun Ye's originally advancing figure was stunned, and his eyes hidden in the darkness kept turning, but after looking at it for a while, he found that he couldn't see anything and gave up.

Strange, did I just hear it wrong?

After staying for a while again, the stairwell was still as silent as before, Yun Ye muttered to himself, and at the same time, his footsteps stepped forward alternately again.

"Click." With a soft sound, Yun Ye's face changed as if he sensed something, and he kicked back violently with his front foot, not caring if he would hit the stairs, and his body flew directly backwards.

But there was a voice, but it was faster than Yun Ye's actions.

A sharp sound of breaking the air sounded from the ceiling of the stairwell, pointing directly at Yun Ye in retreat.

Yun Ye heard the sharp sound of breaking the air, but because he couldn't see anything, he could only swing it out with his senses.

Empty!

The blade that was swung didn't cut anything, and Yun Ye hurriedly drew his knife to defend himself, but after all, he was still a beat slower.

A sharp sound of breaking the air sounded in front of Yun Ye, and then Yun Ye only felt a sharp pain in his chest, as if he had been torn apart by something sharp.

Fortunately, that thing didn't seem to be long enough, and Yun Ye, who flew out upside down, quickly left the range that the thing could reach, but it was still inevitable that a scarlet blood flower was brought up.

Boom! Yun Ye's back hit the cold reinforced concrete wall, and he didn't have time to check the injuries on his body, so he hurriedly rolled over and activated his talent skill "Shadow Hide" at the same time.

As Yun Ye hit the wall and sent out a giant elephant, another sharp wind sound that seemed to cut everything came quickly, but fortunately, Yun Ye grabbed it quickly this time, and the unknown sharp thing did not hit Yun Ye's body, but was fiercely imprinted on the wall made of reinforced concrete.

Syllable! The sound of whipping sounded in Yun Ye's ears, and then the walls shattered, and there was a burst of rubble shooting everywhere.

Yun Ye, who was not far from the wall, was naturally inevitably hit by those gravels, but he didn't move, didn't make a little dodge and resist movements, and let those rubbles hit him.

There were even a few gravels that hit the wound on Yun Ye's chest, causing another sharp pain.

But Yun Ye remained motionless and didn't snort, because Yun Ye knew that once he made a sound.

Only...... Dead!
