The countdown is over, and everything is silent.

Everyone held their breath and did not let go of any disturbance outside the defensive zone.

But there was no movement, and it seemed to be the same as before.

"What's going on?" Some people have doubts, and some people quietly breathe a sigh of relief, hoping that this is just a false alarm.

"Ding, ding, ding!" The calm atmosphere was broken by a mobile phone ringtone, and Bai Yang hurriedly took out his mobile phone, didn't see who the call was, and answered it directly.

"Elder Jiang, what's the news?"

"It's... They're killing each other. Jiang Lao's voice trembled a little.

"Killing each other?" Poplar screamed, attracting the attention of everyone around him, his eyes eager to know what was going on.

"No, it's not, they're it... It's devouring each other. ”

"We put a couple of experimental rats together, and when the countdown was over, they started biting each other until one of them died, and then the surviving rats started tearing at the dead rat's corpse frantically, and a purple crystalline substance was turned out of the corpse's brain."

Jiang Lao almost finished saying this sentence in one breath, and his tone was extremely excited.

"Then one of the rats preemptively ate the crystal, and it is now mutating, yes, mutating, and it is a circle larger than it was."

"And the limbs that used to be more harmonious are now more aggressive, in short, they are sharp teeth and claws, you know what I mean?"

Jiang Lao's usual laughing state was no longer there, and his voice was hurried, wanting to express his meaning in the shortest possible time.

"I understand Elder Jiang." Poplar's eyebrows were furrowed, and he already knew it in his heart.

Old Ancestor had said that the body of the mutated creature might condense source qi crystals, which would be beneficial to human cultivators.

But there was one thing that Bai Yang wanted to miss, and that was the attraction of the Source Qi Crystal to other creatures, and judging from Jiang Lao's feedback, this attraction could be called terrifying.

"Topol, there's a situation." Liu Yuting suddenly spoke.

Bai Yang asked Jiang Lao on the phone, asking him to be careful in everything, and synchronize with him at any time if there is a situation, and then hung up the phone and set his eyes on Liu Yuting.

Liu Yuting didn't speak again, stretched out her finger and pointed to her ear, signaling Bai Yang to listen carefully.

Seeing this, Poplar held his breath, and his sense of hearing turned on with all his strength, and suddenly all kinds of sounds around him came one after another, including the whispering of everyone, and the sound of heavy breathing.

Poplar filtered out the distractions, and then faintly heard a strange sound.

The voice was very noisy, faint at first, but gradually becoming clearer.

"It's—" Poplar's eyes widened, "it's the sound of a mouse, and an even more terrible scream!" ”

"I should have thought of this." Poplar muttered to himself with some remorse.

"What's wrong?" Liu Yuting was close, so she naturally heard Baiyang's words clearly.

"The previous campaign to eradicate the rodent infestation was not enough, and we neglected the area outside the defense zone."

Poplar originally thought that these were not much of a hidden danger, but now it seems that they are the biggest threat, especially after hearing Jiang Lao's news.

"What now?" Liu Yuting asked.

"Sewer ...... at the border of the defense zone"

"Isolation and reinforcement have been done for a long time." Before Bai Yang finished speaking, Liu Yuting already understood what he meant and said directly.

Poplar nodded, closed his eyes in contemplation, and quickly opened his eyes again.

"Half of the mutants in the first line of defense are dispatched and take the initiative. Collect smoke grenades and give them to these mutants. ”

Poplar's eyes were determined, and he continued, "Get them all out. ”

"In addition, synchronize this news to the defense areas of various places as soon as possible, and do not allow them to enter the defense areas through the sewers."

Poplar commanded one by one, and the instructions were quickly conveyed.

When the three patriarchs met with Poplar again, they naturally put the command of the mutants in his hands. Poplar did not shirk, in this special period, there is indeed no one more suitable than him.

Smoke grenades were quickly collected from the soldiers and distributed to mutants preparing to attack.

"Keep your distance, don't disperse, advance outward with the defense zone as the center, and quickly return to the original path after using up the smoke bombs."

Poplar gave another command through the walkie-talkie, but due to the limited distance of the walkie-talkie, these instructions still needed to be passed down layer by layer to cover the entire line of defense.

Not long after, 1 minute later, Poplar estimated that it was almost there, and waved his big hand, "Let's go!" The mutants involved in the operation "Whoa" climbed off the fence and then spread out in a radial pattern towards the area outside the defensive zone.

The guardian team moved in the established direction, until they walked out of a distance of dozens of meters, Wei Dabao took the lead in lifting the manhole cover of the sewer, and the ninth master immediately pulled out the latch and threw a smoke bomb into it, and then re-covered the manhole cover.

Almost every tens or hundreds of meters, the two of them will repeat the above movements, and the cooperation is a bit smooth.

Goodbye to Bai Yang and Liu Yuting, but they were almost empty-handed, their eyes swept around, and their eyes were vigilant.

This is naturally a countermeasure that several people discussed in advance, but at that time, Jiu Ye had something to say, but he was powerless to resist, so he had to obediently become a coolie, who let him and Wei Dabao not have the eyes of the other two?

During the process, the poplar was fully enlightened, always paying attention to the movements around and even underground.

The farther he went, the more he felt a restless aura hidden nearby.

He also tried to observe the situation underground in a perspective way, but it was clear that his heat was still shallow and did not make much difference, and he could only push into the distance by feeling.

When they were about 1 kilometer away, Bai Yang and Liu Yuting stopped at the same time, looked at each other, and saw the solemnity in each other's eyes.

"You hear that?" Liu Yuting asked.

"Right ahead." Poplar nodded.

When the two Nine Masters in the back approached and were about to ask something, Bai Yang made a silent gesture and said softly:

"Obviously, the rats are concentrated in the back section, although I don't know what the reason is, but it can save us a lot of effort."

"Ninth Master, Heizi, I'll add some ingredients later."

"No problem, Ninth Master, I like smoked bacon the most."

"It's rat meat." Wei Dabao reminded.

Without further ado, several people slowly moved forward again, and when they approached a manhole cover again, Jiu Ye's face suddenly became a little ugly, and he also felt that something was wrong.

"So much?" The corners of the ninth master's eyes twitched.

"That's enough for you to eat." Wei Dabao is not a big deal.

"What are you waiting for?" Poplar urges.

Jiu Ye could only bite the bullet, and while Wei Dabao lifted the manhole cover, he pulled out 5 bolts in a row, threw all the smoke bombs in his hand, and shivered when he was done.

"Wait for me where you are." Poplar said, and then disappeared in front of everyone with a "whoosh", and after a while, "swished" back to the same place.

"Retreat." Bai Yang shouted, and then pulled Liu Yuting to run away like a desperate person.

Jiu Ye was still stunned on the spot, and it wasn't until Wei Dabao next to him gave a big mouth that he woke up and sprinted faster.

At a distance of one kilometer, it naturally didn't take much time at the speed of a few people, and by the time they returned to the wall, they had already seen that many mutants had completed their tasks and were waiting solemnly at the head of the wall.

"Can you let go?" Liu Yuting said in a cold voice.

Poplar reacted suddenly, and let go of the little hand that had been pulling all the way in embarrassment.

After a dozen seconds, some of the mutants returned to the wall, but a small number were still missing.

Not far away, the sound of rats moving has gradually begun to be heard, accompanied by a dense and very sharp cry, which makes everyone's scalp tingle when they hear it.

"Prepare for battle." Poplar shouted and set up his Type 95 rifle.

Then, everyone saw a scene that they would never forget.

I saw that a hundred meters away, a black torrent was rolling towards this side, and if I looked closely, what kind of torrent was it, it was completely a mutant rat tide composed of rats the size of a big cat.

The mutated rat has skyrocketed in size, its eyes are scarlet, and its fangs and claws glowing with cold light are the same as those described by Jiang Lao, and no one will doubt that this sharpness can completely disembowel.

At this time, some of the weaker people on the wall had begun to tremble in their legs, and many female mutants even screamed.

Human nature is like this, when a crisis really comes, no matter how strong your faith and confidence in victory you have, instinctive fear will destroy you before the crisis comes.

"If you don't want to die here, just stabilize me!" A loud cry of rage drowned out all the uneasy voices, a little hysterical, but extraordinarily effective.

The voice came from Na Wang Feng.

"Ready to shoot!" Poplar didn't have time to think about it, and shouted vigorously.

"Hit!" When the mutant rat tide had just crossed a distance of 100 meters, Poplar took the lead in shooting, and the first bullet hit the target's head easily and accurately, instantly smashing his head to pieces and splattering blood.

Immediately after, the guns rang out in the sky, and the tongues of fire that flew from the muzzles of the guns compiled a very beautiful barrage picture scroll in the dark night, and the end of the picture scroll was wantonly harvesting countless lives at this moment.

Occasionally, a few mutant giant rats that slipped through the net were shot down by the mutants' precise point shots as they bounced at an astonishing height and were about to pounce on the people on the wall.

The 30 rounds of ammunition were quickly used up, and the barrage began to thin out, and the rat tide took advantage of this to advance dozens of meters.

Suddenly, several thick tongues of fire roared towards the rat tide, and with a few loud bangs, a large swarm of rats was instantly blown into minced meat.

It was a portable rocket fired by a soldier.

The pungent smell of blood filled the entire defense line, and Poplar frowned at the endless army of rats, these mutated rats were simply not afraid of death, and they were completely stepping on the corpses of their companions to advance step by step, and the word timid as rats was completely unrelated to these mutated giant rats.

"Chirp... Pump! In the midst of Poplar's confusion, a loud and strange sound sounded, which could not be concealed even by the dense sound of gunfire and explosions.

At this moment, the rat swarm suddenly increased their speed, and rushed towards the wall of the defense area even more frantically, the distance of dozens of meters was shortened by half in an instant, and the next moment they were about to engage with the people on the wall.
