Li and Quill panted slightly. Although the battle was short, they had used all their strength to kill these Polluters. They were far from Qi Yuan and Gray Robe's calmness.
Under Gray Robe's control, the injured Grade 2 Polluter crawled on the broken corpses of the Polluters, greedily sucking the black mucus from their bodies.
Qi Yuan glanced at the Polluter's body. The grey octopus was wriggling quickly, swallowing the black mucus from the Polluter's body to repair its broken body.
Gray Robe was controlling the Polluter itself, but the octopus?
Qi Yuan vaguely sensed a trace of the Polluter's essence. The human body seemed to be just a vessel, and the octopus Polluter in the body was the true controller.
If his guess was correct, then who was the controller of the intelligent Polluters?
If it was the intelligent Polluters themselves, then how did they control the beastly Polluters?
If it was the Polluter in their bodies, then how did they maintain their human intelligence?
The Polluter swallowed the black mucus, and its severed arm healed at a speed visible to the naked eye. Qi Yuan did not rush it. When the Polluter was completely healed, Gray Robe slowly said:
"There are too many Polluters here. Let it walk at the front."
After witnessing Gray Robe's ability, Feather and Li's expressions became somewhat unnatural. This kind of Mysterious Realm ability to silently control other life forms was too terrifying. Since Gray Robe could control the polluters, he could also control them.
If they really encountered danger, they were worried that they would be controlled by Gray Robe to bring up the rear.
Stepping on the corpses of their comrades to escape was a common thing in the wilderness, not to mention that they were just temporary teammates.
The staircase was even darker than the corridor. The controlled polluter walked at the front. Its bare feet stepped on the stairs, leaving dark footprints that gradually faded away.
Qi Yuan walked about three meters behind the Polluter, constantly maintaining the perception of his surroundings. Before stepping into the old city, Qi Yuan had already stored enough energy and liquid metal in his body to support the following battle.
After more than ten Polluters were wiped out, the Polluters lurking in the building quieted down once again. However, Qi Yuan knew that this was just an illusion. There were still Polluters lurking in the rooms outside the stairwell. They were still in deep sleep, waiting for the night to fall.
Gray Robe took out a mechanical pocket watch and looked at the time.
"There's still an hour before night falls. We need to hurry!"
"Why must we stay on the roof?" Quill suddenly asked.
"The Polluters can run on the walls. Even if we climb to the roof, we won't be able to avoid their attacks!"
Quill's gaze fell on Qi Yuan as she spoke... because Qi Yuan and Wolf's Teeth Hunt, she wanted to get an answer from Qi Yuan...
"I don't know either."
Qi Yuan didn't stop moving forward. Instead, he calmly said, "However, I still suggest that you listen to Wolf's Teeth Hunt's arrangements. Wolf's Teeth Hunt has always had a good reputation. Furthermore, this mission has the endorsement of the Hunter's Guild. I believe that Wolf's Teeth wouldn't dare to joke around with so many people's lives."
Quill fell silent. If it wasn't for Wolf's Teeth Hunt's reputation and the endorsement of the Hunter's Guild, she wouldn't have taken the risk to enter the blue zone and enter this old city filled with Polluters, even if the reward for this mission was very generous.
When the four of them were about to reach the roof, Qi Yuan saw four scarlet words written on the wall at the turn of the stairs — Blood for Blood!
Qi Yuan stopped in his tracks as a strong smell of blood wafted over.
"It's human blood, and the blood hasn't completely dried up!"
Qi Yuan carefully observed for a moment and said in a deep voice, "There are fragments of bone fragments.
"There are also broken bone fragments in the handwriting. It was written directly with a broken arm!"
The few of them instantly tensed up.
"Where did they get a human arm from? Could it be that someone else entered this building before us?" Li asked in a low voice.
No one answered because they all knew the answer.
Not far from the top of his head, there was an intermittent chewing sound, as if someone was eating meat in large mouthfuls.
Li swallowed his saliva. He could already hear the chewing sounds of more than ten Polluters, and their strength was even stronger than the Polluters that appeared before. There was definitely a Rank 3 Polluter among them.
"Can you control a Rank 3 Polluter?" Qi Yuan suddenly asked.
Gray Robe nodded with an ugly expression.
"Yes, but it will take time."
Qi Yuan didn't say anything else. The Polluters' battle was extremely frenzied and wouldn't give him much time.
Using Area Detection, he could already see the position of the Polluters above them. It was at the exit of the staircase above them. More than ten Polluters surrounded the staircase, eating a bloody "feast"!
The human that was surrounded and eaten could no longer be seen clearly. More than half of the body had already been swallowed into the Polluters' stomachs. One could only vaguely determine that it was a man's corpse through a large shoe covered in blood.
"There are more than ten Polluters above, and at least two of them are Rank 3!" Li said with a pale face.
Feather and Li looked at each other with a struggling expression, as if they were hesitating whether to continue forward or turn around and leave.
"It's too late. The Polluters above have already discovered us, and there are also Polluters below coming at us!" Qi Yuan said calmly.
Feather's expression changed. Both his hands turned into six-barrel gatling guns, and the black muzzles pointed at the staircase below.
"We can't wait any longer. Leave the top to me, and the bottom to you guys!" Qi Yuan took out a flash grenade from his pocket.
In order to deal with these Polluters, Qi Yuan had taken many good things from Qu Shi's workshop. Not only did he have a flash grenade, he even brought a plasma bomb!
"Close your eyes!"
Qi Yuan reminded them, and then closed his eyes and rushed up with the flash grenade.
A white light bloomed in the air, and the pitch-black staircase became as bright as day. More than ten Polluters immediately covered their eyes and screamed.
Their eyes had long since adapted to the darkness. Under the sudden illumination of the flash grenade, their eyes looked as if they had been scorched by the sun, leaving behind streaks of black blood.
Qi Yuan closed his eyes. The flash grenade did not affect the area detection at all. He held Doomsday Striker in his left hand and the Decapitator in his right, and rushed into the middle of the Polluters.
Swoosh!
The Decapitator swung its blade horizontally, decapitating a Rank 3 Polluter. Black blood spurted out from the wound on its neck like a fountain.
The remaining Polluters felt the danger and ignored the flash grenade, closing their eyes as they madly rushed forward.
Amidst the chaos, Qi Yuan's expression did not change. He raised Doomsday Striker, aimed at the head of another Rank 3 Polluter, and pulled the trigger.
Bang!
The Doomsday Striker flashed purple, and a gray bullet flew out from the muzzle, piercing the forehead of a Rank 3 Polluter.
Bang!
The Polluter's head shattered like a rotten watermelon, and black mucus sprayed on the wall behind it like a black plum blossom.
The Polluter with its skull split open fell to the ground, but it did not die. It stood up shakily, and the shattered skull slowly healed.
It's still not dead!
Qi Yuan was shocked by the Polluter's strong vitality!
In the next second, Qi Yuan took advantage of the fact that the Polluter's head had not recovered to slash at its neck again.
The Defiler wobbled as it tried to dodge the attack, but its shattered head had obviously affected its movements. There was no way it could avoid the fatal attack.
It was only when the Decapitator chopped off the remaining half of its head that it collapsed, losing all signs of struggle.
Roar!
Roar! The Polluters' frenzied roars echoed throughout the stairwell. The Polluters below were also engaged in battle with the three. Feather's left and right hands turned into two gatling guns, raining down firepower on the Polluters below like cutting grass. The momentum was even greater than Qi Yuan's battle.
Under the deafening gunfire, Qi Yuan was surrounded by a group of Polluters who did not dare open their eyes. The Decapitator in his hands was like the Sickle of the Grim Reaper, harvesting the Polluters' lives in a frenzy.
With each slash, a corpse was decapitated. Without the two Rank 3 Polluters holding him back, the remaining Rank 2 and Rank 1 Polluters could not threaten him at all.
The flashbang lasted for two minutes, and before the blazing white light was extinguished, more than ten Defilers had already died under the Decapitator's blade. The price Qi Yuan had to pay was merely a cut on his arm by one of the Defilers, and that was all.
The battle below gradually calmed down, and the frenzied gunfire from the gatling guns finally stopped. Li brandished his hatchet and split open the head of a Polluter, wiping out the rest of the Polluters below.
The three of them panted as they walked up. When they saw the floor littered with broken limbs and sticky black blood, as well as Qi Yuan who was resting on the stairs, a sliver of unsuppressable shock appeared in their fearful eyes.
There was only one Rank 3 Polluter below, the rest were Rank 2 and Rank 1 Polluters. With two Rank 3 and one Rank 2 Polluter working together, they had almost failed to stop them.
Yet Qi Yuan alone had cut down two Rank 3 Polluters, as well as more than ten Polluters below Rank 3.
This kind of close combat strength was simply terrifying!
Even those veteran Tier 3 Combat Domain Hunters might not be able to deal with so many Polluters so cleanly and efficiently.
Li gave Qi Yuan a deep look. He also had two Rank 2 Combat Domain Hunters, but compared to Qi Yuan, they were practically trash.
"We're almost at the top floor!" Qi Yuan suddenly said.
Gray Robe took a deep breath, a gray light flashing in his eyes as he slowly said:
"There's an Asterite on the roof!
I can feel my ability being suppressed! "
Yu and Li's expression changed. They weren't as sensitive to Asterite suppression as the Mysterious Domain. If there really was an Asterite on the roof, this wasn't good news. Although the Polluters would also be suppressed, there were more of them. Once surrounded, they might not even be able to escape.
Only Qi Yuan's mind was moved. He could already clearly sense the location of the checkpoint. It was on the roof of this building. If there really was an Asterite on the roof, then perhaps the checkpoint was on the Asterite.
"I'll go up and take a look first!"
Qi Yuan quickly walked up. He had a vague premonition that the star energy stones could suppress and interfere with other people's abilities, but it was very likely that they would not be able to affect him.
The others quickly followed. Regardless of whether there was an Asterite on the roof or not, they didn't dare stray too far from Qi Yuan. Only Qi Yuan's powerful strength could bring them a trace of security in this dangerous old city.
Soon, Qi Yuan reached the end of the stairs. However, he didn't reach the roof. The top two stairs leading to the roof had actually been destroyed.
Qi Yuan looked at the broken stairs in front of him in shock. He cursed in his heart and almost couldn't help but vomit.
This was definitely the work of an intelligent Polluter. Those simple-minded Polluters definitely wouldn't do such a thing!
After the three of them came up, they also stopped in front of the broken staircase. Gray Robe muttered to himself, while Yu and Li looked at Qi Yuan.
"What do we do now?"
After going through two fierce battles, they had already realized that Qi Yuan was the real thigh of this team. Therefore, Qi Yuan's opinion began to become the team's leading will.
Qi Yuan silently looked at the broken staircase. His Area Detection had already "seen" the scene on the roof.
In the middle of the cement in the middle of the roof, there was a fist-sized black stone embedded in it. The Sign-In Beam that only he could see was suspended above that stone.
Although he had never seen an Asterite before, Qi Yuan was sure that the black stone was the Asterite that Gray Robe spoke of.
Qi Yuan's heart thumped. He could clearly feel the restlessness of his innate ability. Not only was it not suppressed by the Asterite, but every cell in his body had also begun to become active.
They were longing for that Asterite!
They wanted to eat it!
Not too far away from the star energy stone, four powerful bestial defilers were silently surrounding the star energy stone and squatting on the rooftop.
Eight eyes stared straight at the black stone embedded in the cement. There was some fear in their eyes, but also some desire.
Not too far away from the four beastly corruptors was a man in combat uniform. He stood at the edge of the rooftop with his back to the star energy stone, and there was a bloodstained cigarette dangling from his lips.
Under the blowing of the wind, the dark red flame of the cigarette flickered, and the green smoke drifted with the wind.
Polluters can also act so pretentious?
Qi Yuan silently ridiculed.
After "seeing" the man's face, Qi Yuan's pupils suddenly shrank.
This man was not only an intelligent polluter, but also an "acquaintance"!
One-eyed Qiang!
He was the one-eyed wolf who used him as bait to lure the Corrupt Wolf and was then killed by him.
Although One-eyed Qiang's black hole-like left eye had completely recovered, Qi Yuan still recognized him at a glance.
One-eyed Qiang didn't even change his clothes. He was still wearing the combat uniform he wore on the day of his death!
Why is One-eyed Qiang here?
Can a dead person become a polluter?
Qi Yuan suddenly recalled the scene of him killing the one-eyed tyrant, and his heart gradually sank to the bottom of the valley.
One-eyed Qiang has discovered me!
The pair of eyes that peeped at me from the roof is him!
The words "Blood for Blood" written on the wall were also written by him for himself!
Qi Yuan tightly held Beheader and indifferently stared at One-eyed Qiang.
So what if you become a polluter?
If I can kill you once, I can kill you a second time!
You are the first ability user I killed!
You will also be the first intelligent polluter I killed!
In the new era of power, a broken staircase can't stop an ability user from reaching the top. It's just a little troublesome.
Using the area detection, after confirming the environment of the roof, Qi Yuan turned and left the staircase and walked into the corridor of this floor.
"Follow me!"
Qi Yuan walked through the corridor, turned around a few empty rooms, and then stopped.
Asterite was above them, and the checkpoint was also directly above them. It was only two floors away from them!
"Blow this place up for me!" Qi Yuan pointed to the lamp at the top of the room and said.
Feather nodded. The six-barreled Gatling gun aimed at the direction Qi Yuan pointed and began to wildly bombard it.
Bang bang bang bang bang!
Although the cement was hard, under the bombardment of the Gatling gun, it was like paper. Soon, a hole about one meter in diameter was blasted out by Feather.
Dust fluttered down. Qi Yuan squinted his eyes and slightly bent his legs. Then, he jumped and directly grabbed the exposed steel bar in the cave. Then, he pulled hard and directly went through the hole to the upper floor.
