Fang Rin took a step, the Ugin Sword slashed continuously, and the Ugin Sword once again exerted great power, and the mutant rats that could defend against ordinary blades all died under Fang Rin's sword without any resistance.

After killing all the mutant rats, Fang Rin repeated his old trick and sealed the passage inside with cold ice again before stopping.

In this way, the four of them were locked in this section of the passage.

"Li He!"

Zhang Feng held Li He, who had fallen in a pool of blood, his face full of sadness.

"Li He, if you support it, we will save your ......"

At this moment, Li He is already more out of breath and less in air.

The head injury was very serious, although Wang Ming's blood on the side was not less, but it was not critical and not serious.

Fang Rin just stood aside and watched, without speaking.

Li He gave him a good impression, he was relatively kind, he was the oldest of the four of them, and they were also comrades-in-arms who had fought side by side, but at this moment, he could only watch him die, and he couldn't change anything.

Fang Rin clenched his fists.

This feeling of powerlessness disgusted him.

This scene, he knew that it would come sooner or later, although he was mentally prepared, but when he really came, it was so annoying, and a sour feeling flashed in his heart.

Li He didn't have any last words, but handed over the map he had secretly drawn before to Zhang Feng.

He died with a faint smile, probably without care, on this day, he was already prepared!

"Red Flames! Nie Yu! You're all going to die! ”

Holding the map in his hand, Zhang Feng's face was unprecedentedly cold, so cold that he couldn't look at it directly.

"Mourning, you must live well in order to take revenge!"

Fang Rin gave a sigh of comfort and came to the frozen passage.

He stretched out his hand and pressed it to the ice, and soon, the frozen passage melted into several tiny holes that led to the outside.

The snake and rat battle outside is clear at a glance.

From the current point of view, the rat swarm has the upper hand.

It's not for nothing that snakes fear rats.

The mutated rats are no longer as fragile as they used to be, and their teeth can easily tear through the scales of ordinary snakes, but the counterattack of ordinary snakes cannot cause fatal damage to mutant beasts.

And the snake venom is also minimized in the power of mutant rats.

Many poisonous snakes finally bite the weakness of mutant rats, but the snake venom can't help each other in a short time.

This gives the mutant rats the upper hand in this battle.

However, when some mutated snakes of the size of a giant joined the battlefield, the situation of the snake group began to improve a little.

It is worthy of being a natural enemy, and it is also a mutant beast, and the mutant snake has a strong lethality to the mutant rats, whether it is the bite force or the venom, it can produce fatal lethality to the mutant rats.

The battlefield was suddenly in a state of stalemate.

On the side, Zhang Feng and Wang Ming also stepped forward to watch.

"There are so many mutant beasts, if only both sides died together, if this is brought back to the Optimus Tower, it will be a huge fortune!"

Wang Ming said in amazement.

"Bring it to the towering city, it's worth more!"

Fang Rin couldn't help but agree.

Mutant beasts are at least not a rarity in the Sky Tower, but in the towering city, they are real scarce goods, and they are very valuable.

"I don't know where Nie Yu and the others are hiding?"

Zhang Feng's eyes wandered, and he looked everywhere, but unfortunately it was all a chaotic battlefield, where was the shadow of Nie Yu and the others?

Looking at Zhang Feng's revenge-seeking appearance, Fang Rin was really afraid that he would do something stupid.

So he changed the subject:

"There should be very few mutant rats in the cave now, let's go in and investigate, maybe there will be an unexpected harvest."

This sentence immediately reminded Zhang Feng that when he was outside before, Fang Rin had already told him about the abnormality of the mutant rat group, all the rats were mutated, there must be a reason for this, and the target of Nie Yu and the others should also be this secret.

It is absolutely impossible to let Nie Yu and the others take advantage.

Zhang Feng immediately said: "I'll go with you!" ”

"Young Master......"

"You stay! Wang Ming, you have injuries on your body now, just recuperate here, Fang Rin and I will go deep into the rat den to explore...... Take good care of Li He's corpse, if possible, we must take him away for burial, and we must not let his corpse fill the stomach of this group of rats. ”

"Good!"

Wang Ming did not refuse.

He is injured, and if he goes on, it must be a burden, so it is better to wait for Fang Rin and the others here.

Resolution by all means.

Fang Rin broke through the ice inside and walked out, then sealed the passage and strengthened the ice before leaving.

Inside the dark passage.

Fang Rin and Zhang Feng held weapons in their hands, and walked forward slowly, their steps were extremely gentle, this mouse hole was deep and dark, although there was fire, but they still couldn't see far.

They are always on the lookout for sudden attacks.
