ps: If you can watch it, please vote for the recommendation with your hands, it is better to reward, and ask for everything with great sincerity.

The groundwater accumulated in the subway line quickly gushed out of the subway line after the return of the blast wave, carrying the corpses of mutant rats and doped blood, and poured into the sea outside the subway line.

Looking at the stagnant water flowing out quickly, Chen Xiao's face became serious, and in front of the subway line, as the stagnant water disappeared, there was also a dense chirping sound.

In the stagnant water on the subway line beneath your feet, you can soon see mutant rats that have been washed away with the current.

"Prepare for battle."

With the rapid drop in the water level, at the end of the straight subway line, a large group of mutant rats has entered their eyes.

Chen Xiao raised the staff of ruling, he did not choose to move forward, but stayed here, waiting for Long Yan and the others behind to rush over.

"Ai, wall of fire."

Looking at the group of mutant rats that were getting closer and closer, Chen Xiao ordered decisively.

Immediately, four strong pillars of fire appeared directly on the subway line, and there was a huge collision with the flowing water, and a large amount of smoke quickly filled the front of the entire subway line.

Fire and water are incompatible, and the temperature of the wall of fire quickly vaporizes the stagnant water below, at the cost of the flames close to the subway line, slowly extinguished.

However, the wall of fire burning on the stagnant water still easily blocked the path of the mutant rat group.

The fierce flames made it impossible for the rats to move an inch, and they were blocked in front of the wall of fire.

These mutant rats were obviously more intelligent than the previous mutant ants, and they all just wandered in front of the wall of fire, and did not rush over without thinking.

"Cut off the back road, surround it and burn it to death." Chen Xiao commanded again.

There is a very traditional way to deal with monsters that won't take the initiative to enter the wall of fire, and it's also the easiest way.

Xiao Ai waved the blood drink in his hand again, and behind the rat colony on the subway line, another wall of fire burned.

The two walls of fire, one in front and one in the back, directly cut off the back road of the rat colony, and the scope of the fire wall burned directly on the entire subway line.

Thick water vapor and smoke soon enveloped the surrounding passages.

Xiao Ai's attack did not stop because of this, and the mutant rats surrounded by the two walls of fire were all anxiously scurrying.

The third wall of fire was directly attached to the back of the first wall of fire and burned, and a dozen mutant rats were directly surrounded by the wall of fire in the center of the flames in the chaos.

The terrible screams echoed on the subway line in an instant.

One by one, the rats with flames began to scurry, making the rat swarm behind them even more chaotic.

The fourth wall of fire forms in front of the second, compressing the space for the rat colony to move around once again.

Then there were several walls of fire in a row, and after more than ten seconds, the entire swarm of rats was surrounded by the wall of fire.

The shrill screams of rats, accompanied by mist and smoke, swept across the subway line.

The rats, who were wrapped in flames, managed to escape from the wall of fire, and their lives came to an end.

When the stagnant water had run out, revealing the tracks on the subway line, the walls of fire were extinguished one by one.

Although a large number of exhaust vents quickly sucked out the water mist and smoke, the entire subway line still emitted a thick smell of burning and choking smoke.

If it weren't for the fact that there was still standing water on the rails, I am afraid that the sleepers below would have burned.

Most of the hundreds of mutant rats that rushed over also turned into charcoal, and even until the flames were extinguished, Chen Xiao and the others could still feel the heat in front of them.

On the concrete walls around the subway line, all the equipment has disappeared in the fire, and the iron line has been directly melted by the heat.

At the end of the flames, more and more mutant rats gathered on the subway line.

These mutant rats did not dare to advance, not only were there hundreds of burned companions in front of them, but there was also the heat left by the burning wall on the ground.

The heat radiation in the air had not yet dissipated, and the thick flames of the wall of fire seemed to discourage them from moving on.

The section of the subway line that had been burned by the wall of fire seemed to have become a forbidden place for a while, blocking Chen Xiao and the others and the mutant rats who continued to run over.

Chen Xiao didn't act in a hurry, Xiao Ai also stopped attacking, her attack range was within the range of vision, and those mice in the distance were naturally within the attack range.

The reason for not attacking is simple, the number of mutant rats gathered behind is not enough.

There was a crisp sound of footsteps behind him, Long Yan and the others also trotted over, and before they could ask curiously, Chen Xiao said, "Let's go!" ”

The goal of this trip is very simple, to clear the subway line 1 on the island, and all the mutated creatures that exist on the subway line are the targets to be eliminated.

Walk on the subway line and head towards the mutant rats still hovering beyond the extinguished wall of fire.

The closer you get to where the wall of fire has burned, the temperature rises in a straight line.

When Chen Xiao stepped into the place where the fire wall had just burned, her forehead was already covered with beads of sweat, and the plastic soles of her feet seemed to be melting.

"Don't set it on fire." Chen Xiao explained to Xiao Ai that although the fire wall in the subway line has a good effect, the impact left behind is not small, and the large amount of smoke produced is also very uncomfortable.

At this time, seeing Chen Xiao and the others approaching, the mutant rat group on the opposite side also became restless, showing their fangs as sharp as knives, and squeaked at them.

This voice Chen Xiao is very familiar with, when he first encountered these mutant mice, the mutant rats used this voice to summon their companions.

This time, Chen Xiao did not stop them from summoning reinforcements, and the swarm of rats on the subway line was best gathered together, so as not to look for them.

"Be careful."

Chen Xiao explained, although the individual strength of these mutant rats is not a threat, once the number increases, it will be very troublesome.

Ludao, a developed city, is not lacking in rats, even if the probability of mutation is not high, but the huge number of ethnic groups, accumulating 1.8 million mutant mice, there is no problem at all.

The subway line is a nice battlefield that guarantees that the back will not be surrounded, which is conducive to group fighting.

And the small space is also very suitable for everyone's attack.

The wandering rat swarm rushed at them when they were less than fifty meters away.

Chen Xiao was about to make a move, when Long Yan stepped forward and said, "These miscellaneous fish will be handed over to us." ”

The raised Staff of Judgment was put down, Chen Xiao nodded and did not refuse, and said, "Let's sweep the formation." ”

Long Yan nodded seriously and shouted to the seven awakened people he brought behind him, "Let's go." ”

As soon as Long Yan's voice fell, four awakened people in camouflage uniforms jumped suddenly, crossed the heads of everyone, and at the same time pulled out the alloy long knife on their bodies, and rushed towards the swarm of rats, extremely fast.

This is the first time that Chen Xiao has paid serious attention to the team under the command of Long Yan, these people are obviously from military backgrounds, and they all have a strong military temperament.

And none of these people have modern weapons, and there is even an awakened person with an alloy longbow and a crossbow on his waist.

It is worth noting that these people are all above level twenty-five, and among them, Long Yan is already almost level thirty, and he is only one step away from the third order.

Dealing with this group of mutant rats of about level 30 with more than 20 levels, Chen Xiao is actually not optimistic.

However, as soon as these people came into contact with this group of mutant rats, he immediately changed his previous attitude.

The four awakened people with long knives have obviously systematically learned knife techniques, and they are very ruthless.

The four men in a circle formed a quadrangular shape, each swing aimed at the mutant rat's slender head.

There was a shallow white edge on the knife, and each cut was enough to make the mutant rat ineffective.

Longbow Awakener and Long Yan, who are in charge of long-range attacks, seize the most critical opportunity every time to supplement the attack blind zone of the four people.

These mutant rats can only pounce, and it is difficult to help these four awakened people for a while.

However, the four people used the attack net composed of arms and long knives to completely block the entire mutant rat group.

The close cooperation has completely made up for the gap in strength between the two.

Chen Xiao, who was on guard, also slowly relaxed, and he now somewhat understood why Long Yan dared to come with only a team to clear the rat swarm.

Because they have such strength.
