The rat's burrow is not as dirty and not smelly as imagined, after all, they are fifteenth-level demon beasts, not ordinary rats that steal food and eat. You must know that if a fifteenth-level demon beast is put in the lower realm, it will be a heaven-destroying existence. With just one mouth, you can bite a master like Zhuo Donglai to death.

It's so convenient that you don't need to actually dig up the soil to sneak underground. Du Feng hid in the soil like this, quietly following the rat swarm. The cave is much more complex than in his phenomenon, it can be said that it has nine twists and eighteen bends, and it is like a labyrinth to go around.

Du Feng tracked and memorized at the same time, otherwise, even if he had an earth escape technique, he might not be able to find a way back. The IQ of this mouse seems to be higher than expected.

They didn't go to the center of the mountain, but stopped somewhere underground. It's a relatively spacious thing, and it's kind of a gathering point. Hundreds of rats were waiting here, and there were other rat formations coming through the other passages, all carrying food.

What a situation, it seems to be holding a ceremony. Du Feng had an ominous premonition that he seemed to be in trouble. Originally, I just wanted to kill some mice and take the demon pill back to exchange for contribution points. Why do rats gather more and more, and each team carries offerings, which is obviously a form of sacrifice.

It is common for human beings to engage in sacrifices, and there are really not many demon beasts to engage in sacrifices, unless they are wise demon cultivators. But this is the range of the Heavenly Realm, and it is near the Yuxian Gate, so there should be no demon cultivators. Could it be that one of the rats suddenly opened his wisdom and became a refinement?

Thinking of this, Du Feng couldn't help but shrink into the soil. If there is really a rat that has become a sperm, its divine sense will inevitably become stronger, and it is very likely that it will find itself.

Fortunately, the rats didn't seem to notice him, but after gathering the offerings, they began to place them on a stone platform. Although they have no hands, they can be placed respectfully. A group of rats put their heads on top of the offering and gently placed it on it.

The carcass of a porcupine had just been placed on it, and it withered like a withered flower. The flesh began to dry up, and the blood began to dry up. Now Du Feng figured out that those rats ate all the internal organs not because of hunger, but to clean up the corpses.

They seem to think that the internal organs are dirty, so they have to clean them up, leaving only the flesh and the demon pill and the head, so that they can be qualified offerings.

That stone platform was really strange, sucking up a demon beast corpse and not shedding a drop of blood, just a slight burst of red light, and then disappeared. Then the corpse of a poisonous snake was also put on the table.

These rats are really hard work, you must know that snakes are natural enemies of rats, especially poisonous snakes are no problem to kill a group of rats. But in order to have a good offering, they actually killed the poisonous snake. It is also to clean the internal organs, leaving only the skin and flesh and the demon pill.

The rats that placed the vipers on the stage obviously had a sense of pride, as if they looked down on the other group of rats that had captured the porcupine.

The rat still had a heart for comparison, and Du Feng almost thought that he was dazzled. The monsters in my impression, especially those that live in groups, shouldn't be chaotic. When they encounter a little thing, they riot, either desperately rushing at night, or scattering and fleeing.

But these rats not only know how to work as a team to kill monsters that are stronger than themselves, but also compare them in terms of offerings. The team of rats that captured the porcupines looked visibly ashamed. The richness of expressions is simply not lost to humans.

Du Feng felt that these rats were even smarter than some human warriors. If they are allowed to grow, it will not only be a hidden danger for the Feather Immortal Sect, but also a hidden danger for the entire Heavenly Realm.

There are a lot of burrows dug by the rats underground, not only the mountain where the Yuxian Gate is located, but also the surrounding mountains and ground, I am afraid that they have also dug through them. The human warrior lived a leisurely life on it, unaware that he was actually surrounded by a large swarm of rats.

Du Feng's scalp was a little numb when he thought of this, and at this time, Xiao Hei spoke: "Brother Du, don't be excited, I'll give them a big gift in a while." ”

It's been brewing a thunderball, brewing to the size of a watermelon, and then compressing it to the size of a quail egg. Then continue to brew, and then compress the small one when it gets bigger. Du Feng thought that it was playing with getting bigger and smaller, but now it doesn't seem to be like that.

Xiao Hei is constantly pressing Lei Yuanli into a ball. Because it's too big and not flexible enough, it's compressed repeatedly. This trick can't be used in normal times, because it's too time-consuming to compress. But right now, it's just hiding in the dirt, and the other party doesn't notice it.

Du Feng felt the purple thunderball slightly, and couldn't help but pout. When he really wanted to throw it, he had to stay away. Xiao Hei is too crazy, I'm really not afraid of blowing up the mountain.

The sacrifices continued, and the offerings were placed one by one. At first, Du Feng was a little shocked, but then he became numb. Because in the process, new teams of rats are constantly coming, each carrying their own offerings.

Not to mention poisonous snakes, even fifteenth-level wild wolves, leopards, and black bears have been brought by them. I don't know how much sacrifice these rats have made to be able to kill a demon beast that is so much stronger than themselves. But their pious attitude when sacrificing is really moving.

"Ready!"

Xiao Hei reminded Du Feng that it was about to make a move.

"Hmm!"

Du Feng also felt that it was time to make a move, because there was no new rat team coming, and the offerings were almost there. If they wait until they have all the offerings in place, there won't be any moths, so they might as well blow up the bunch now.

Du Feng used the Earth Escape Technique to move back first, and he was ready to evacuate.

"Huh!"

A small purple thunderball spewed out from the small black mouth, incredibly fast. As soon as it squirted out, it drilled back into the small world of necklaces. Du Feng didn't have time to see the results, and used the earth escape technique to desperately flee out. Then I heard a loud bang from behind, and the surroundings began to shake rapidly, as if there had been an earthquake.

As he fled, he poked out a wisp of consciousness and observed the situation behind him. It doesn't matter if you don't look at it, you will be shocked when you see it. So a whole bunch of rats, blown to pieces by the thunderball. Because in a relatively narrow space, they have no time to escape, and the explosive energy cannot be vented, almost relying on their bodies to resist.

It's nothing, the most terrifying thing is that it's time like this, and they're still guarding that altar.
