The battle seemed to be endless. The mutated rats didn’t seem to know what fear was. They surrounded and attacked Gray one after another. Even Gray himself had become somewhat numb from the attacks.
Fresh blood soaked Gray’s entire body. Even his pitch-black eyes had become bright red and demonic. Everything he saw was blood-red.
Some of the fresh blood belonged to the mutated rats, and some belonged to Gray himself.
Compared to the scales on his entire body, the scales on his lower abdomen were much weaker. A peak Level 3 mutated rat had taken advantage of Gray’s unprepared state to tear off a corner of the scales on his abdomen.
However, just as it was about to make another move, Gray stretched out his claw and smashed it into meat paste. Then, he sent it into his bloody mouth..
“Kacha, kacha…”
With the sound of bones breaking, Gray chewed and swallowed the half-dead mouse.
However, at this time, Gray couldn’t care less.
Burning blood had consumed too much blood essence. He urgently needed to consume a large amount of food to make up for the exhaustion of his stamina.
And the flesh of this mutated creature was the best supply for him at the moment.
“Ding dong, it has been detected that the host is devouring the flesh and blood of a Level 3 mutated rat. Evolution Points + 30. Obtained sharp teeth gene…”
Listening to the system’s notification quietly, Gray did not hesitate to put all his evolution points into the venom. Right now, he needed a large amount of venom to support him in winning this bloody battle.
“Roar…”
With a low roar, the venom in his mouth, which was as much as a casserole, shot towards a corner where many mutated rats had gathered.
“Zi, zi, zi…”
After a series of sounds of corrosion, another large group of mutated rats were buried here.
At this time, out of instinct, Gray subconsciously sensed that something was wrong. A hint of surprise suddenly appeared in the depths of his eyes.
“After waiting for so long, I’ve finally got you,” Gray cursed in his heart.
Following his heat sensing ability, he would definitely be able to see that a black shadow was constantly moving toward him.
It was fast, unimaginably fast, and was faster than him sprinting at full speed.
This speed was probably faster than a high-speed train.
Its extremely fast posture was like a sharp sword, shuttling through the vast rat group.
And this figure, if Gray’s guess wasn’t wrong, should be the rat king of this group of mutated rats.
The strength of a peak Level 4 mutated beast was not to be underestimated!
And Gray, who was reserved previously, had been on guard against it. Only it and those Level 3 mutated rats could break through its Level 6 scales defense.
And now, after waiting for so long and seeing its people being continuously tortured and killed by him, it finally couldn’t sit still anymore and stood out.
Seeing the main character finally appear, it was as if all the anger in his body had found a right outlet to vent. Grinning, the tail on Gray’s back was already swaying gently.
All of a sudden, a black shadow instantly flashed through the air, charging straight at Gray’s face.
“Die!”
In the midst of his explosive shout, Gray, who was originally tired of dealing with the rats, suddenly whipped his tail on the ground. He didn’t look like he was about to lose his strength due to the rats’ human wave tactics. The tail on his back was even more tensed up in the air.
“Rumble…”
Accompanied by the terrifying whistling sound of the air, the air waves continued to churn. A whip-like tail, which looked like steel, ruthlessly lashed out at the rapidly approaching black shadow.
At this moment, the air seemed to be compressed. The powerful air waves continued to churn. As a Level 4 mutated creature, the rat king naturally felt it, too.
Looking at the changes in front of him, even the rat king, who was well-informed, could not help but have a drastic change in its expression.
However, due to the inertia of his speed, he was unable to control his extremely fast posture.
Faced with the constant risk of death, the rat king, who was unable to dodge, could only let out an ineffectual and furious cry to vent the fear in his heart.
“Squeak, squeak!”
A series of panicked cries reflected the fear and panic in the heart of the owner of the voice.
However, this did not change the fated outcome. Gray’s steel tail continued to attack without slowing down, ruthlessly whipping forward.
Following that…
With a loud rumble, a black shadow brought out rings of air currents, like a rapidly moving meteor.
Finally, when the meteor touched a huge rock wall, it stopped, releasing waves of blood mist.
Amidst the blood mist, the entire pit was filled with an indescribable chill.
It was cold and suffocating.
It was as though it was pressuring all living things around it to the point where they could not breathe.
Looking at the crumbling rock wall, one could see that the ferocious Level 4 mutated rat king had actually been whipped into the depths of the rock wall by Gray. And it was unable to move for a long time.
From the extent of the cracks on the rock wall, it was at least three to four meters deep.
As for the fate of this mutated rat king…
“A Level 4 mutated rat is still not good enough…”
Looking at the rat king that was on its last breath, Gray could not help but sigh.
They did not lose this battle unjustly. Although they had begun to develop their intelligence, they were still animals and lacked intelligence.
In the battle before, Gray had always reserved some strength in order to deal with this mutated rat king.
Although Gray was the peak of a Level 6 mutated creature, it was like a Dragon Gate to this group of low-level mutated rats.
But in front of this mutated rat which used the human wave tactic, its strength was ultimately limited.
If at this time, this Level 4 mutated rat king got close to him, even he wouldn’t be able to escape the fate of being seriously injured. At that time, if he was seriously injured, it would be a fool’s dream to think of escaping.
Therefore… This plan was necessary.
He had actually pretended that he was about to use up all his strength and wasn’t able to fight against the enemies’ human wave tactic. The ancient people would never be deceiving.
Looking at the results now, his previous efforts were indeed not wasted.
However, at this moment, an unexpected change finally happened.
The rat king that was deep in the rock wall seemed to have used the last bit of strength in its body to let out an extremely shrill cry.
“Squeak, squeak!”
“Could this be…”
Looking at the surrounding rats that were starting to riot, Gray’s face was filled with shock.
These rats seemed to have gone mad, and an indescribable deep redness appeared in the depths of their eyes.
“No way that this is possible.”
Seeing the situation in front of him, Gray knew that the situation was serious.
Not only did these mutated rats that had lost their leader not lose their will, but because of the mournful atmosphere, they became even more berserk and terrifying.
Screeching after screeching, countless mutated black rats pounced over recklessly. They did not even care about the remaining poison on the ground. It was as though nothing in the world could stop them.
