Batu Cave, the whole cave is rocky, sparse grass and trees, it doesn't seem to have the slightest fairy atmosphere, if it is not for the discovery of yin ghosts and white bones, it is not an exaggeration to say that this is the Demon Cave.

The cave that the immortal key enters is divided into four levels, of which the heavenly level is the highest, and the yellow level is the lowest, even the lowest-level bronze key has a chance to enter the heaven-level cave, but the probability is lower than winning the lottery.

This time I entered the Xuan-level Upper Grade Cave Mansion, which can only be regarded as a medium difficulty, and it would be even better if I entered the Ground Level Cave Mansion at the next level, although it was only one level worse, but the rewards were very different.

There was no formation protection in front of the Batu Cave door, and Su Ming released a few puppets to explore the way in front, but after entering this cave, there was no danger.

The light of the cave was dim, and after walking dozens of meters, I saw an oil lamp hanging on the wall, the dim light was swaying, and under the firelight, the surrounding shadows also became abstract and hideous.

The candlelight flickered, pulling Su Ming's shadow for a long time, but at this time, the shadow seemed to shake slightly, and then a black shadow appeared from his shadow, and Su Ming didn't notice it at all, still looking at the jumping candlelight in a daze.

Suddenly, the shadow suddenly opened its big mouth and bit directly at Su Ming.

"Can't wait?" Su Ming's voice suddenly came.

The ghost creature was slightly stunned, and before he could react, he suddenly felt his eyes light up, and then he heard thunder roaring!

"Boom!"

The thunder flickered, and the dim corridor was as bright as day for a while, and the black shadow was directly wrapped in the thunder, and a scream sounded, and a monster stumbled out.

This monster has sharp horns on its head, a hard shell on its back, sharp claws, and fierce eyes and chiseled teeth, it is a kind of monster called Shadow Domain, this kind of monster likes to lurk in the shadows, and when people approach, they will hide in the shadow of people, and then suddenly jump out of the shadow and eat people when they are unprepared.

Su Ming waved his hand and hit another Aoki divine thunder, only to see a flash of thunder, and it hit this monster in an instant. Yu Ying struggled to escape, but the two divine thunders had already seriously injured him, and before he could hide in the darkness again, he was completely killed by Su Ming's more than a dozen sword lights.

The strength of this monster is not high, but it is a little troublesome to hide in the shadow and sneak attack. After dealing with the monster, Su Ming continued to walk forward.

After walking for a while, the light behind him disappeared without a trace, and the surroundings became dark again, this gloomy atmosphere made Su Ming can't help but raise his vigilance, and the two puppets have been exploring the way.

After walking for a few more minutes, there were only two puppets in the empty corridor, and there was a thumping echo as they walked, which was even more infiltrating in this environment where they couldn't see their fingers.

The eyes of the two puppets shone a bright light, illuminating the front, there were a lot of white bones scattered on the ground, and there seemed to be countless eyes staring at him in the dark, Su Ming's heart moved slightly, and he slowly raised his head to look up, only to see that in the darkness, countless dense red eyes were quietly staring at him!

With just one glance, Su Ming felt his scalp tingle!

"Fluttering!"

Those blood-red eyes moved instantly, and countless dark red bats fluttered their fleshy wings and pounced towards Su Ming, these bats were not large, but there was a metallic cold light flashing on the claws.

Su Ming's face changed slightly, an aura shield rose instantly, the Xuanjia shield flew up quickly, and then more than a dozen sword lights flashed, and the bat that rushed to the front was split in two by the Qingyu Bitter Bamboo Sword.

Immediately after Su Ming pinched the magic trick in his hand, sixty-four flying swords shuttled back and forth, weaving a sword light in front of him, only to see those bats rushing up like moths to a fire, and in the blink of an eye, they fell like rain. As soon as these bats moved, it was as if they had triggered some mechanism, and countless bats flew towards here from all directions, but in the blink of an eye, they formed a wall and surrounded Su Ming to death.

The level of these bats is not high, and the amount of blood is also small, but the number is as if it is ruthless and endless, the claws are extremely sharp, and they also carry toxins, which constantly flicker the Xuanjia shield in front of Su Ming.

Sixty-four green jade bitter bamboo swords were like meat grinders, and the bats kept falling, but in the blink of an eye, a thick layer of bat corpses piled up on the ground.

Su Ming's sword light was like a swimming dragon, constantly killing the bats around him, the number of these bats was too much, even if each one only had 5 points of cultivation, in just a quarter of an hour, he had gained 2,000 points of cultivation.

After killing for a long time, but the number of bats did not decrease at all, and Su Ming's mana was also consumed by one-third, seeing this situation, Su Ming patted the Qiankun bag, and a bronze palace lamp appeared in his hand.

Immediately afterwards, a flame rose, and the flames instantly ignited the surrounding bats, and then in the next second, the two flames of dark blue and fiery red were like fire dragons, quickly burning in all directions, but it was just a few breaths, and the entire passage was empty, and a large amount of fly ash gargled and fell, and for a while, Su Ming's cultivation value also rose a little.

Seeing that all the bats were burned to death, Su Ming withdrew his mana, and the fierce and powerful flame dragon just now also dissipated and returned to the wick of the bronze palace lamp.

Retracting the Qianyang Liangyi Lamp, Su Ming took a few pills to recover his mana, and then continued to move towards the cave, these two levels seem to be easy to pass, but if it is someone else, if so many bats do not break through as soon as possible, they will definitely be consumed here in the end.

If there was no Qianyang Liangyi Lantern, it would not be easy for Su Ming to pass here.

The two puppets were already scarred, but fortunately, this thing had rough skin and thick flesh, and Su Ming continued to let them explore the way ahead. There was no danger in this corridor next, and soon Su Ming came to the end of the corridor, and a hall appeared in front of him.

Su Ming approached the hall, and a foul smell came from the hall, which seemed to be the smell of some kind of rot. Su Ming let the two puppets enter the hall, the hall was empty, only the footsteps of the two puppets came, just when Su Ming thought it was safe, suddenly a black shadow appeared, and then one of the puppets shattered.

The other puppet immediately attacked, but a flame struck the shadow, which only paused slightly, and then sent the puppet flying with a claw. Before the puppet landed, the black shadow rushed up again, grabbed the puppet, bit it, and in the blink of an eye, the puppet was violently destroyed and flew out.
