However, after walking for a long time, I didn't encounter a single mutant rat.

It seems that all the mutant rats have run out of their burrows and are fighting the snakes outside.

Fang Rin and Zhang Feng's footsteps couldn't help but be a little faster.

After drilling through the long acupuncture hole, the more you go inside, the more spacious it becomes.

"It's really strange that these rats have built a cave on such a large scale, I'm afraid it is not only for passage and breeding, but also for other purposes." Zhang Feng said in a suppressed voice.

"Agreed!"

Fang Rin walked forward vigilantly, and said: "The place we just passed through has a large amount of rotten flesh, it should be a food storage point, a mouse stores food, it is understandable, but a large group of rats live together, and a fixed food storage point is also set up, which shows that this group has a clear division of labor, a complete system, and there may even be a king of the group." ”

"It makes sense, the more I think about it, the more I realize that these rats are not simple, so many rats live together, and they can still live in peace, which is already very incredible in itself."

The two of you say a word, I say a word, and the communication is constant.

And as it continues to deepen.

The sheer size of this cave shocked Fang Rin and the others.

Countless passages are cross-connected, and if you don't pay attention, it's easy to get lost, and the places they have walked along have been marked before they can continue to move forward with peace of mind.

I don't know if it's because of the battle outside, but the two of them almost didn't encounter mutant rats in the cave.

Occasionally, I encountered a few, and they were all eliminated with the power of thunder.

I don't know how long they walked, but finally, they found a place that seemed to be extremely important to the mutant rats.

Because there are "heavily guarded!" ”

A group of mutant rats were guarding the door of a cave, very vigilant.

Almost all the mutant rats in the entire cave have already come out of the cave to fight the snakes, but the mutant rats here are not moving, which means that there must be a greater threat here than the snakes outside.

"What should I do?"

Zhang Feng asked quietly.

"Hard work!"

Fang Rin's answer was simple.

Because although there are a lot of mutant rats here, he has the Ugin sword in his hand, and he is not afraid, and the mutant rats here are obviously alone, and almost all the rats in the entire cave have gone out to participate in the big battle.

Once they fight here, the other party will naturally not be able to find reinforcements.

At least for a short time, they will only face this group of mutant rats in front of them.

Since this is the case, Fang Rin doesn't want to waste time, and it is the fastest way to solve the enemy and understand the secret.

"You go first, I'll give you a sweep!"

Zhang Feng raised his hand and said unceremoniously.

"Hmm!"

Fang Rin nodded.

In the face of these mutant rats, Zhang Feng's combat power was obviously not enough.

Fang Rin didn't hesitate at all, he rushed out directly, and in an instant, he was already covered in ice armor, holding the Ugin Sword in his hand, and went straight to the mutant rat.

The mutant rats guarding the cave were suddenly extremely irritable when they saw Fang Rin, and rushed up one by one, but when they faced Fang Rin, they couldn't shake it in the slightest.

The razor-sharp Ugin sword could easily tear through their defenses, killing them incessantly.

In a short time, Fang Rin had already killed all the mutant rats in the vicinity.

Coming to the entrance of the cave, Fang Rin was stunned for a moment.

I saw that inside the entrance of the cave, there were dense and countless little mice.

The larger ones are the size of the bowl, and the smaller ones are only the size of a fist.

However, no matter how big they are, they are still much worse than the size of adult mutant rats, and it is clear that this is the feeding place for the young of this group of mutant rats, and the number is unimaginable.

And Zhang Feng also followed.

"Damn! So many rats, it's disgusting! ”

This scene is indeed too disgusting for human beings.

The huge cave was full of small rats, and there was not even a place to put their feet, and if a person with dense disease saw this scene, he would be absolutely stupid.

But soon, Zhang Feng cast his eyes on another object.

In the center of the cave, there is a stone pillar.

At the top of the pillar is a red spar that is emitting a faint halo.

This red spar, with a faint halo, illuminated the entire cave, and all the mice seemed to have a layer of pale red soft light.

For the appearance of Fang Rin and Zhang Feng, these little mice didn't feel anything.

They just lay there silently, bathed in the soft red light.

It seems that this soft light is all they have.

"Zhang Feng, look, these little mice are not all mutant mice, you look at those mice that are so small that they can't even open their eyes, they are obviously no different from ordinary mice, but you look at those slightly larger mice, all of them are mutant mice."

Zhang Feng took a closer look, and sure enough.

I looked up at the red hedron again.

Zhang Feng exclaimed: "You mean, these rats themselves are not mutant rats, but after being illuminated by this red spar, they have mutated and become mutant beasts with evolutionary physiques. ”

"I don't think there's a better explanation."

Fang Rin nodded solemnly.

If it is really as they speculated, then the value of this hedron is simply immeasurable.

If this spar can also have an effect on humans, whoever owns it will simply have endless strength.

"Get it!"

Zhang Feng's eyes were red, staring at the spar.
