After being expelled from the sect, I became the villain mentor

The cave was cold and damp, and there was no dry firewood. After running for a long time, everyone was cold and hungry, so they took out talismans, lit them, and placed them on the ground to use as firewood. Such a first-level fire talisman could burn for as long as two quarters of an hour.

The orange-red flames dimly illuminated the quiet cave, and everyone finally felt a little warmth.

These flames seemed to have awakened something. A slight whooshing sound suddenly rang out in the originally quiet cave. Water droplets dripped from the dark cave ceiling, and pairs of blood-red eyes suddenly appeared above everyone.

Soon, the entire cave wall was filled with blood-red eyes with faint red light, and sharp voices were heard one after another.

Obviously, the creatures that had been dormant here for a long time were extremely hostile to these people who suddenly broke in, and were even more disgusted by the flames that suddenly ignited.

Zhizhi~!

When the dark creature that covered the sky rushed towards them, everyone looked up in shock.

"Oh no, this is a bloodthirsty bat!"

The strange cries of the bats became sharper and sharper, and the sound waves seemed to be tangible, spreading continuously, and everyone was awakened.

There is a clear record of blood-thirsty bats in the "Treasure Record of Ten Thousand Beasts". They like to suck blood, are best at sound attacks, and have severe neurotoxins. If bitten by them, you will probably fall into a coma immediately and will not be able to wake up.

Everyone took out their weapons and chopped down the bloodthirsty bats that pounced on them one by one. However, many people were still bitten by the bats and fell to the ground within three breaths.

The sharp sound waves in the air made everyone's eyes dizzy and their heads felt dizzy.

Yan Yijian raised the heavy sword, slashing at the bloodthirsty bats while slapping a Vajra Talisman on himself and Lan Qingqing.

The dazzling golden light spread out, and the bodies of the two men became as hard as diamonds, directly breaking off the sharp teeth that were biting towards them.

The others raised their long swords, drew sword flowers in the air, and then quickly erected a shield made of spiritual power to block the bloodthirsty bats rushing towards him. They cast one spell after another, and each time there was a scream from the bloodthirsty bats.

"Senior Yu Nian, there are too many bloodthirsty bats, and the cave exit is right in front of us. Why don't we rush out..." Zhang Yuan summoned a magic weapon and said loudly.

When everyone heard this, they became eager to move and headed towards the mountain pass.

"Wait a minute!" Yu Nian drew his sword and chopped down the bat while trying to stop these people, but it was too late. Dozens of fleeing cultivators he met on the road had already rushed out.

Everyone turned around and looked at Yu Nian in confusion, as if asking for an explanation from Yu Nian.

"What are you going to do outside? There are crazy monsters everywhere outside. It's not a safe place."

Yu Nian fired several icy arrows to knock down the bloodthirsty bats that flew overhead. He remained vigilant against the bloodthirsty bats lurking in the sky and said slowly, "The entrance and exit of this cave are so narrow that those huge monsters will be blocked from entering. We should hold the hidden cave in the valley and wait out this period of monster riots."

"But these bloodthirsty bats..."

Most of these bats are in the Qi training stage, with only a few dozen in the foundation building stage. The one with the highest cultivation level is only at the peak of the foundation building stage.

But unfortunately, they are social animals, there are quite a lot of them, they reproduce very quickly, and they are extremely sensitive to blood. When they smell blood, they will pounce on you like leeches with their bellies bursting. Sometimes, some attacked animals have no time to resist before the blood-thirsty bats rush over and suck away their blood in an instant, turning them into dried goods.

Moreover, these bats can also emit a kind of sound waves, which have a huge interfering effect on the spiritual consciousness of cultivators, just like the sound of magic, which can easily make people fall into the trap without being prepared.

"Everyone sit down, don't move, and don't talk!"

As soon as Yu Nian finished speaking, he put Feixue back into the scabbard, released a stream of spiritual power to stop the bloodthirsty bat in the Foundation Establishment Stage that was rushing towards him, then sat down on the ground and took out a guqin from the storage ring.

When she was in college, there was an elective course called Qin Ge Chuan Xi, so she could play the piano, but she hadn't played it for many years and was a little rusty.

She touched the strings of the zither and the intermittent sound of the zither echoed in the cave. Not long after, the sound gradually became smoother and spread throughout the cave with spiritual power, like a breeze on the lake on a summer night, making people feel relaxed and refreshed.

A group of bloodthirsty bats that were originally attacking everyone were disturbed by the music and circled back and forth in the air, their eyes were red and they kept squeaking.

Several larger bloodthirsty bats were still circling around the crowd, making strange squeaking noises and even starting to attack each other madly, biting and wrestling in the air.

Everyone was extremely confused as they looked at these bloodthirsty bats that suddenly went crazy, biting and running around everywhere.

While playing the piano, Yu Nian signaled to everyone not to make any sound, and then conveyed the message to them. Only then did everyone understand why.

These bloodthirsty bats couldn't see them at all.

Bats have extremely poor eyesight, and because of the darkness, they are basically blind. Their eyes are just like decorations. Bats usually locate themselves and determine direction by emitting sound waves and waiting for them to be transmitted back.

By playing the piano, Yu Nian disrupted the sound waves that the bats used to detect people, and interfered with them, returning wrong information to the bloodthirsty bats. These bloodthirsty bats then mistook their own kind for intruders and attacked each other.

I have to say that the law of nature is fair. When this world opens a window for you, it will close a door.

As a group of monsters, the bloodthirsty bat has hallucinogenic toxins in its fangs. It also has super strong sound waves to interfere with and control its prey, identify directions, and has strong survival skills. In addition, its powerful reproduction ability, which makes some groups jealous and troubled, makes the entire group always a behemoth in the dark, and its number is astonishing.

But the shortcomings of these bats are also quite obvious. They cannot appear during the day, are most afraid of sunlight and mithril weapons, and are basically blind.

Moreover, it is difficult for this kind of dark creature to develop intelligence and become a great demon.

The melodious music not only made these bloodthirsty bats kill each other, leaving corpses piled all over the ground, but also soothed the uneasy hearts of the people, making them feel much calmer.

A quarter of an hour later, bursts of extremely shrill screams, mixed with the strange cries of bloodthirsty bats and the roars of terrifying monsters, rang out from the valley outside the cave, echoing throughout the valley and reaching the cave.

It resounds through the sky and lasts for a long time.

Everyone was shocked, got goose bumps all over their bodies, and their scalps felt numb. They looked at Yu Nian with eyes full of gratitude.

Sure enough, what they would face outside would be those monsters that would come in like a tidal wave, which would be even more dangerous than inside the cave.

These screams, mixed with the bloody cries of pleasure from various monsters, and the sound of tearing each other's flesh as they started their gluttonous feast, were extremely tormenting to the ears. Those cultivators who had just been with them were turned into piles of bloody and rotten flesh in the blink of an eye, and were swallowed by the monsters.
