A low roar came out, and the red eyes seemed to be even more terrifying, bright like two bright lights, and Xiao Yu was able to see its expression with his own eyes at this time.

It was a huge humanoid creature two meters tall, covered in gray fur and flesh-winged, like a giant humanoid bat.

Xiao Yu glanced at it, made a decisive move, and with a bang, a ball lightning appeared in his hand, and he sent it out directly.

Thundered!

The entire cavern seemed to be trembling violently, and the sand and stone Quirrell shook as if it were about to collapse.

"Roar!"

The huge humanoid bat was startled, he was a creature similar to a yin spirit, and he was most afraid of things like thunder and lightning.

Sou!

Its speed was incomparable, and it turned into an afterimage in an instant, running deeper into depth, and with Xiao Yu's skills, he couldn't catch up.

"What a speed!"

Xiao Yu was slightly surprised, but at the same time, he was not shocked by the power of the move just now, this was what he had just learned from Lin Xuexin, and it was worthy of the mastery of Yuqing Palace.

"Where to go?"

Xiao Yu laughed, and also exerted his speed to the extreme, turning into an afterimage, and continued to advance towards the depths of the ground.

But soon he began to be shocked.

Swish!

Swish!

Swish!

Deeper, countless red bloody eyes opened their eyes at this moment, densely packed with thousands of them, their whole bodies were blood-colored, crystal clear, and extremely weird. Xiao Yu was taken aback.

"How can there be so many?"

Xiao Yu was so surprised that he was about to step back, but it was too late.

Rise!

Thousands of blood-colored bats are moving, and the heavens and the earth are going to lose color, dense, overwhelming, and the water surrounding this place is impassable, and there is no way to escape.

Xiao Yu sighed, he finally knew why there were so many bats here, as long as he took a bite, that person could turn into white bones in an instant.

However, there were no humanoid bats at this time, all of them were extremely small, but Bai Sensen's teeth were not weak at all.

Some even had blood stains on them, and it was unknown what they were feeding on.

In the face of such a terrifying scene, even though he was surrounded by thousands of bats, Xiao Yu was still calm, and thunderbolts were constantly thrown out in his hands, pinching them casually.

Magnetic!

Magnetic!

The arc danced, and pieces of bats continued to fall down like dumplings, shocking and terrifying.

But despite this, more and more bats still surround them, and the fresh flesh makes them invigorated and not afraid of death.

Moths to the fire!

Xiao Yu sneered.

Immediately, with a bang, blood-colored flames suddenly rose up outside his body, and the momentum was so majestic that even the space trembled a little.

This is the fire of the soul, and all along, Xiao Yu has been able to use its power slightly while being tortured by the strange fire and wanting to die.

"Boom!"

The flames rose, and a large number of bats suddenly let out a miserable scream, vaporizing in the high temperature, they all belonged to the cold things, and they were most afraid of yang energy.

In the end, I don't know how many bats fell, they finally stopped, and after being sure that they couldn't help Xiao Yu, they all flew back one by one and didn't pay attention to it.

"Humph!"

Xiao Yu snorted lightly and began to move deeper, he wanted to know what secrets existed in this cave.

Deeper, there was an eerie aura all around him, which made him uncomfortable for a while, and he felt chills all over his body.

"Am I underground?"

Seeing the terrain expanding and the surrounding area becoming wider and wider, Xiao Yu couldn't help but feel nervous for a while, he didn't know if he should go any further.

"Let's take a look!"

In the end, he gritted his teeth and chose to move on. I don't know how long it took, but finally a soft light seemed to flicker in front of his eyes.

Swish!

Without the slightest hesitation, he instantly sped up and rushed over.

Thump!

This is, a huge humanoid bat fell to the ground, his whole body was covered with blue blood, giving people a shock, grinning his teeth and revealing a hideous color, as if he was going to fight Xiao Yu desperately.

"Come on, then!"

Xiao Yu smiled and nodded.

Rumble!

The monster immediately roared angrily, and didn't care about anything else, so it was directly charged, and the speed was extremely fast and menacing.

Xiao Yu smiled and made a move, his figure was even more weird, and he used the operation exercises that he had learned from Lin Xuexin, and suddenly the temperament of his whole body changed.

Xiao Yu jumped into the air, feeling as if he was going to be proud of this world, without any discomfort, sure enough, only the exercises of this world are the most suitable for this world.

"Huh!"

A light flickered, and the energy in Xiao Yu's hand changed for a while, and the cold sword shadow under the stroke made a sonorous sound, becoming more and more crisp.

Sou!

The humanoid bat called Xiao Yu was in full momentum, and he also jumped, and his body was about to retreat, but it was already over.

Xiao Yu's sword is as dexterous as a dragon, unpredictable, and with a kind of unstoppable, it draws a shock in the sky.

Burst!

In the end, the bat's head was cut off by Xiao Yu with one move, and the blue blood sprayed wildly, straight down.

"It's too weak!"

Xiao Yu shook his head, in terms of combat effectiveness, this huge bat is not as deterrent as the tens of thousands of blood bats, which is really sad.

The next moment, he finally walked into the place where the light was, and saw the glowing object clearly, which turned out to be a piece of jade.

Xiao Yu walked in and looked around, it seemed to be a secret room, and when he walked here, it seemed to be at the end.

At first, he only looked at Baoyu and didn't pay attention to anything else, but soon, his face changed, and not far away, a tall figure was sitting cross-legged next to him, motionless.

"Senpai!"

Xiao Yu was frightened, what kind of existence is this person who can not emit any breath at all, and return to the basics?

To his surprise, a tall man with a mantle and a disheveled cape ignored him, still motionless, like a stubborn stone.

Xiao Yu was shocked, stepped forward step by step, looked at it deeply, and relieved himself, because he found that this person seemed to have passed away for an unknown amount of time.

"But since he is dead, why is his body still shining, is it the legendary flawless physique?"

Xiao Yu glanced at him and found that his whole body was bright and crystalline, and he was still lifelike after being dead for a long time, like a living thing.

"Well, he's got something in his hands!"

Xiao Yu lowered his head and saw that one of his left hands was still holding a parchment roll, and he didn't know what it was.

Xiao Yu had the courage to make a move, he just grabbed the parchment, and only heard a click, and the two fingers of the man holding the parchment roll were completely broken like porcelain.

Xiao Yu was stunned.
