A sharp whistle came quickly from behind Wei Yi. Wei Yi listened to the sound and recognized the position, raised a foot and swept back.

There was a crisp sound of "pop", and Wei Yi kicked the incoming object away. He looked back and was shocked to find that it was a palm-sized guinea pig. The little mouse was kicked by his strong force and fell into a crack in the wall. Bright red blood stained a large area of the wall.

And that's just the beginning. The walls around Wei Yi suddenly cracked at the same time. Countless guinea pigs emerged from those cracks. Their eyes were blood-red, and they screamed and rushed towards Wei Yi frantically.

"Da, da, da." The sound of gunfire rang out instantly. Countless mice have become corpses before they hit the ground. Without waiting for Wei Yi to react, dozens of soldiers quickly rushed up from behind him.

"Let's go, we'll cut you off." Someone said quickly to Wei Yi.

Wei Yi nodded, thanked him, turned around and quickly ran towards the road he had come.

The sound of gunshots and fighting quickly sounded from behind Wei Yi. Some people screamed and fell to the ground, and some people were injured and cried out in pain. But no one backed back.

"Hold on! Don't let this stuff pass. Wei Yi heard someone shouting loudly, "Even if you die, you have to block them here for me." ”

Wei Yi's eyes were instantly blurred by tears. He didn't dare to pause, he didn't dare to delay even a second. The breath of the person lying in his arms was getting weaker and weaker, and he had to send her out as soon as possible.

"Thank you! Thank you. Wei Yi silently thanked the soldiers behind him in his heart. He didn't dare to stop for a moment. Soon, he rushed to the entrance of the tunnel.

"Come on, there are wounded. Dr. Lee was seriously injured! Come on! Wei Yi shouted loudly towards the narrow entrance.

When several soldiers heard the news, they quickly rushed over. With their help, Wei Yi sent Li Xiaohui out first. Just when Wei Yi wanted to bend down and get out, from behind him, there was a sudden sound of Si Xi Suosuo. It was the sound of a large group of animals running fast.

"Quick, send her to first aid, she's dying. Just go! Wei Yi was shocked in his heart, and said eagerly to the soldiers, "There is a large group of mutated rats behind me, and I have to stay here." Take her away. We must bring her back to life. Please! ”

The soldiers answered, hurriedly carried Li Xiaohui and left quickly. Wei Yi turned around and lit a few cold fireworks, and quickly threw them into the passage in front of him. The light of the cold fireworks illuminated the tunnel in front of Wei Yi's eyes. The flickering light of the fire pulled Wei Yi's shadow to writhe from time to time, as if a beast of prey was slowly raising its fangs.

He slowly drew his sword, squinting his eyes and staring intently into the depths of the tunnel. A murderous aura gradually emanated from Wei Yi's body. One, two, three, more and more mutated mice appeared in Wei Yi's sight.

They're small, but they're incredibly fast. In the blink of an eye, they rushed in front of Wei Yi.

"Xiaohui's account, let's do a good calculation, you damn white-haired brutes." Wei Yi looked at the mice that were approaching him, and his eyes flashed with a terrifying cold light.

This time, he was really angry, he was really angry. No one can hurt his beloved. Neither humans nor these mutated creatures can be.

"You all die!" Wei Yu said, the long sword in his hand flashed rapidly. A silver sword curtain instantly spread out from his hand.

Flesh and blood are flying, and corpses are everywhere. Just in the blink of an eye, the first few layers of mice at the front became a few large lumps of minced meat. The wall in front of Wei Yi was also sprinkled with the blood splattered by the mice.

The sound of "zi, zi" also quickly came from the wall with the splash of blood. Wei Yi was stunned, and hurriedly raised his eyes to look at the wall stained with the blood of the guinea pig. He suddenly found that everywhere that was contaminated with the blood of these mice was rapidly dissolving.

And that's not all. Wei Yi looked down and saw that the long sword in his hand was also being rapidly corroded. He hurriedly shook his hand, and quickly shook the residual blood on the long sword away. But the entire sword body has been slightly damaged. One small pit after another appeared on the originally smooth and flat sword body.

"Not good. This blood is poisonous. Wei Yi was shocked. This time, he had to be more careful. Only this longsword could be used on him now. He didn't dare to use that powerful short knife easily.

After all, in the depths of this tunnel, there are still Li Mingyu and those soldiers who have not yet exited. Wei Yi didn't want to bury all those people alive in this tunnel for his own reasons.

"Damn it. How the hell did these things come out? Wei Yi muttered to himself. The long sword in his hand connected the dots, changed the flirtation, and picked it into a thorn. With every sword, he must hit a guinea pig. For every sword stab, a guinea pig falls to the ground and dies.

His swordsmanship is so superb that he keeps this gap impassable. But unfortunately, the number of those guinea pigs is endless, and it seems that there is no end in sight. No matter how Wei Yi slashed and killed, the number of those mice not only did not decrease, but continued to increase.

As more and more corrosive blood came out of the killing, Wei Yi felt that the long sword in his hand gradually became a little dull.

There was a soft "pop". Wei Yi stabbed out a sword and knocked a guinea pig away. But not long after the mouse hit the ground, it continued to rush back unscathed.

"Oops!" Wei Yi knew that something was wrong. The sword in his hand changed to stabbing again. A silver sword curtain instantly unfolded in front of him. With just a few breaths, nearly a hundred guinea pigs became dead souls under Wei Yi's sword.

But what followed was not the dawn of victory, but the bigger troubles. The sword in Wei Yi's hand was so corroded by the blood sprayed by the mice that it could no longer be used. In the attack just now, the long sword was instantly broken into two knots due to corrosion.

"Damn it." Wei Yi threw the remnant sword in his hand at a mouse that pounced on him. The remnant sword pierced the mouse fiercely, drawing a graceful arc in the air, and slamming it down into the surging swarm. There was a commotion among the rats, but they soon recovered.

The mice were pouring towards Wei Yi in a steady stream. Endless. And Wei Yi had no other weapons in his hands at this time. He quickly reached out to pull out the dagger. But as soon as his hand touched the blade of the knife, he immediately thought of what Li Mingyu had said to him before.

"Damn!" Wei Wei stomped his foot, turned around and quickly got out of the tunnel. He glanced quickly at the room outside the tunnel, stooping down to pick up a short wooden stick.

"Get the hell out of here!" Wei Yu let out a loud shout and swung the stick in his hand towards the entrance of the tunnel. A guinea pig that was rushing out excitedly was instantly slapped back by Wei Yi. Wei Yi could almost hear the unwilling screams of the little mouse.

The corners of Wei Yi's mouth curled, and his hand did not pause, and he shot it again and again.

In the crisp sound of "pop, pop, pop", one after another mice were slapped back into the tunnel by Wei Yi. However, the swarm of rats is too large in number. Wei Yi could only hold on to the entrance and exit of the tunnel very reluctantly.

But it would be extremely difficult for him to disperse the rats, or to take a step further. But in order to prevent these rats from rushing out of here, Wei Yi had to continue to hold on to them.

He kept swinging the wooden stick in his hand, knocking back one guinea pig after another. One crazy guinea pig after another, desperately running towards the exit of the tunnel.

Hit.

Rush out.

Hit again.

The battle instantly came to a stalemate. And Wei Yi's arm gradually became a little numb as time passed. The situation is becoming more and more unfavorable for Wei Yi.

At this moment of crisis, a loud "bang" suddenly came from behind the rats. A violent wave of anger stirred up the rat swarm. Many of the mice panicked and hit the wall headlong and passed out in an instant.

"Get out of here!" Li Mingyu's shout, along with that wave of qi, quickly reached Wei Yi's ears. With the arrival of Li Mingyu, the pressure on Wei Yi was suddenly lightened. Wei Yi was overjoyed, and hurriedly added force in his hand to drive the rats into the tunnel.

The sound of "da, da, da" gunshots rang out quickly after that. In such a situation, the rat swarm finally collapsed completely. They fled in all directions, panicking. There are quite a few unlucky mice that have been trampled into meat by the panicked rats. What's more, he mistook the wall for an exit and slammed into it, killing himself.

The tide turned in an instant. Wei Yi and Li Mingyu and the others who rushed back joined forces and quickly dispersed the rat group. But they couldn't wipe out the nimble little things, and could only watch as they burrowed into the cracks in the walls and vanished.

"Let's go!" Li Mingyu rushed to Wei Yi's side and said quickly, "You go take care of Xiaohui, I'll take care of it here." ”

As he spoke, he threw a punch behind him. A huge force instantly struck down the tunnel into the distance.

With a "bang", the sound of a heavy object falling to the ground quickly came. But soon, the sound of running was heard again in the distance.

"What's that?" Wei Yi asked in surprise.

"Giant ants." Li Mingyu replied briefly.

He waved his hand at the soldiers who were hurrying back and said, "Some of them left quickly with the wounded. The rest stayed. You get the particle cannon right away. That thing is better than my fists. ”

The soldiers agreed, and quickly divided into two teams. One group carried the wounded on their backs, and as Wei Yu hurried away, the other team stayed where they were, and together with Li Mingyu, they stopped the huge creatures crawling in the depths of the tunnel.

A battle ensued in an instant.

Wei Yi followed the departing soldiers and quickly rushed out of the underground research room. The soldiers on duty outside the research room quickly ran towards the medical center with Wei Yi and the wounded. The rest of the soldiers quickly built fortifications and called for support.

A big war is about to begin.
