As we went deeper, the corpses of some mutant bats also appeared along the way, and it was obvious that the first few teams of people had already fought with the mutant bat swarm. Pen, fun, pavilion www. biquge。 info

These mutant bats, which are only F-level dangerous, naturally can't resist the invasion of overrun warriors, but what they rely on is not individual strength.

Even though it had been cleared several times by the first few teams of centaurs, when Bai Yuxi passed by, the cave was still full of swarms of giant bats.

Many of them were still lying on the ground and gnawing on the corpses of their kind, and as soon as they were alarmed, they immediately rose up like a black cloud, and screamed sharply, and flew towards the white jade seal riding on the "Lightning Falcon-2K".

With an enemy of this level, Bai Yuxi was too lazy to attack.

Several gyro flywheels popped out of the Lightning Falcon-2K, and the volley exploded into a sawsaw ring that swirled around him at high speed, slicing all mutated bats that approached him into fragments.

The splattered blood and the screams of dying made people's scalps tingle for a while, and this kind of scene of corpses strewn all over the field, no matter how many times I watched it, I couldn't get used to it, it was really disgusting.

In this underground cave, I didn't know that there were so many mutant bats.

Because Bai Yuxi followed the traces left by his predecessors, and did not explore those branch caves.

Therefore, on the ground along the way, like a thick carpet, are the bat corpses left behind when the previous teams passed by.

At this moment, these dead mutant bat corpses are being eaten by the same kind and a large number of insects, and the terrifying and disgusting picture can make people regret it for half a year at a glance!

Bai Yuxi forcibly endured the nausea and erupted, and the "Death Curtain" composed of gyroscopic flywheels wiped out these bats that were not afraid of death at all, and the piled up corpses almost blocked the cave passage.

These mutant bats living in the underground cave network are conservatively estimated to be at least a few million in size, and he alone cannot kill them all.

Therefore, Bai Yuxi did not entangle, and after clearing the road blocked by the bats, he accelerated his speed.

But if you can't go far, you will be surrounded by bats from the caves that extend in all directions, and you will have to carry out another round of slaughter.

The most terrifying thing is that the bat corpses left behind make the swarms of insects in the cave start a gluttonous feast like the New Year.

Countless insects, like rivers of water, came out of the cracks and under the rocks, lying on the bat carcasses and gnawing on them.

Only then did Bai Yuxi know why there were so many kinds of insects in the cave, and the number was so huge.

No wonder there is no trace of mutation, but such a large group can be bred in such a narrow and cramped space.

The flesh and blood of mutated creatures are rich in very rich "ultra-active bioenergy".

This "super-active substance" itself is a kind of accelerator, and human beings can get a great improvement in their physique after eating it, not to mention these little bugs.

Although they did not acquire direct mutations, they did cause their fecundity to increase dramatically, and their reproduction rate increased to an alarming level.

The reproduction ability of insects is already amazing enough, a single female worm can hatch thousands of offspring at a time, and the reason why it does not flood is thanks to the suppression of tens of millions of mutated bats in the cave.

But this has created a peculiar food chain in this barren underground cavern with only bryophytes.

Insects eat moss, bats eat insects, and when bats die, they are eaten by insects, and insects that absorb super-living substances reproduce like crazy, and then feed more mutated bats to reproduce...... In this way, a virtuous circle has been formed.

Although it's not a demon-level researcher like a female scholar.

But Bai Yuxi can still surmise that this huge mutant bat group should have bred in the last few months after the spring flowers bloomed!

After all, winter is not the time for moss to flourish, and only when moss begins to grow in abundance can insects with food reproduce in a large way.

And only a large enough number of insects as food can prompt mutant bats to reproduce their offspring without any scruples.

The breeding period of ordinary bats is only one and a half months, and a litter can give birth to about four small bats, and the reproductive ability is slightly weaker than that of close relatives mice.

But after mutation, their reproductive ability has increased several times or more than tenfold, and the mutated baby bats can acquire the ability to forage for food on their own within a few days, and then mature and enter the breeding period in just seven to ten days.

With this explosive breeding ability, it is not difficult to understand why there is such a large number of bats in this underground cave.

If it weren't for the mutant bat population, which was so large that even the underground caves could no longer accommodate it, and began to flood to the outside world, causing the extraordinary incident of bats attacking people in the surrounding towns and villages in the Besan area, I am afraid that no one would have noticed it here, and it has unknowingly formed a threat.

After all, the supernormal realm's current ability to monitor overlapping and abnormal points is still very weak, and it is relatively easy to find those that are directly exposed to the outside world.

Once hidden in a cave like this, or isolated by thick dirt and rocks, it is almost impossible to detect.

Bai Yuxi alone has encountered several times, such as the mutant toad in the underground fortifications of Tieting Village, the mutant rat in Hualan Mountain, etc., all of which were discovered after the mutated creatures formed a scale.

Bai Yuxi felt the need to inform Su Xiaoke of this discovery immediately, after all, there was a tide of mutated creatures near the prism base, which would not only threaten the safety of the main base, but also increase the possibility of the base's location being exposed.

I tried the communication device, and sure enough, I had lost contact with the outside world.

From the "Lightning Falcon-2K", Bai Yuxi took out a metal ball the size of a baseball.

After activation, it hummed and trembled and levitated, and quickly flew back the route he had come.

The code name of this thing is called "carrier pigeon", and it is a device that is used to support the communication base station built into the "Lightning Falcon-2K".

It can not only transmit messages in an environment of communication barriers, but also use it as a relay station for communication signals to enhance communication strength and distance.

But not long after Bai Yuxi released the "carrier pigeon" and continued to move forward.

An emaciated figure turned out of the fork in the road.

After looking at the newly added mutant bat corpses on the field, he quickly chased after them.

Strangely, whether it's insects that cover the ground like a carpet, or mutant bats that hover like dark clouds.

He didn't seem to be aware of the figure's presence, and even if he stepped on it directly, no insects or bats attacked him, as if he didn't exist......
