This black mist seemed to be human, with no face, only the outline of a person, and slammed towards Li Xuedong and Huang Yiyan.

Huang Yiyan didn't see this kind of thing, but suddenly felt a cold all over her body, and couldn't help hugging her arms and looking around vigilantly.

Li Xuedong has spiritual eyes, so he can see clearly.

When the black mist rushed over, he suddenly shot out a Tiangang True Fire and threw it at the black mist.

The terrible and gloomy scream suddenly sounded, and the black mist suddenly dodged the moment it touched the Tiangang True Fire, and at the same time, a powerful force surged over, Li Xuedong only felt that his body was like a piece of paper, and he was instantly blasted away by this terrifying force, crashing into the opposite wall, making a muffled sound.

Li Xuedong only felt a sweetness in his throat, and a trace of blood seeped out along the corner of his mouth.

"Brother Li, are you okay?"

Huang Yiyan saw that Li Xuedong suddenly flew away, so frightened that she hurriedly ran over to hold him up, and asked with concern.

Li Xuedong nodded, wiped the blood from the corner of his mouth, and stared at the black mist that had regathered again.

At the same time, the Tiangang True Fire burned in the palm of his hand, as long as the black mist dared to pounce again, he would definitely not show mercy again.

When the black fog rushed over just now, Li Xuedong attacked in a hurry and suffered some dark losses, although the power of this black fog was extremely great, but Li Xuedong believed that it was still not his opponent, but he didn't know what this thing was.

The black mist in front of him was different from the Yin Spirit, although it looked very similar, but its strength was incomparably stronger than the Yin Soul, and even Li Hongshu was not its opponent.

Seeing Li Xuedong staring at the other side, even if Huang Yiyan couldn't see it, she understood that there would definitely not be only her and Li Xuedong in this basement, and there was also an invisible, terrible thing.

"Brother Li, what the hell is this?!"

Although Huang Yiyan is an ancient martial arts cultivator and a master of Xuan-level cultivation, she didn't expect that she was no different from ordinary girls in the face of this kind of invisible and intangible.

Li Xuedong shook his head and said, "I can't say it, you hide behind me first, I want to see what this thing is capable of." ”

The humanoid black mist seemed to be very jealous of the Tiangang True Fire in Li Xuedong's hand, and did not attack it again.

Since the other party was afraid of the Tiangang True Fire, Li Xuedong immediately rushed forward decisively, grabbed the Tiangang True Fire and blasted towards the humanoid black mist.

The humanoid black fog didn't expect Li Xuedong to dare to take the initiative to pounce over, so frightened that it screamed.

The screams are strange, as thin as mosquitoes, but they feel like they're coming from another dimension, giving people a deep and incomprehensible feeling.

Under the continuous attacks of Tiangang True Fire, the humanoid black mist was beaten thinner and thinner, and finally after a long miserable scream, it disappeared completely with a bang, and then a gray bead fell down, making a crisp sound on the floor.

Li Xuedong picked up the gray bead, and just wanted to inspect it, his face changed instantly, and a powerful and cold yin evil aura actually rushed into his body, and his spiritual vision even saw that the humanoid black mist that had been destroyed by it just now was about to invade his will.

"Give me the body...... I want your body...... I'm the Red Blood Emperor......"

"Get out of here!"

After Li Xuedong sensed that something was wrong, he roared angrily, picked up the Tiangang Technique, and forcibly forced out the evil spirits that had invaded his consciousness.

It turned out that what remained on the gray bead was a trace of obsession with the black mist just now, if it was an ordinary ancient martial arts cultivator, such as Huang Yiyan, I am afraid that it would be plotted by it.

It's a pity that Li Xuedong cultivates the Tiangang Righteous Qi Technique, and this kind of yin obsession is nothing to him at all.

When the last trace of obsession was dissipated by Li Xuedong with his true qi, the originally gloomy basement instantly became warm, no longer like an ice cellar just now.

Huang Yiyan quickly noticed a change in the temperature in the basement, and showed surprise on her face: "Brother Li, did you kill that thing?"

Li Xuedong nodded, staring at the gray bead in his hand, but he was thinking about what he said when the black mist invaded his will just now.

'Possession of the body...... Red Blood Emperor ......'

Li Xuedong didn't understand the meaning of the black mist's words, could it be that this black fog had something to do with the Red Blood Emperor.

Li Xuedong now has some memories of the Medicine King, but in these memories, he didn't find anything about the Red Blood Emperor.

Although the Red Blood Emperor didn't find it, he knew what this gray bead was, it was the Yin Soul Bead.

The humanoid black mist just now was actually a ghost cultivator, a wisp of yin soul, cultivating by devouring people's essence and flesh, and those who suddenly disappeared in the basement before were probably devoured by the ghost cultivator, so they disappeared like the world evaporated.

The Yin Soul Bead is the essence of ghost cultivation, and it does not do any good to ordinary people, and it will even be affected by its yin and evil aura.

However, for the dead, the Yin Soul Bead is a very precious existence.

If a person has just passed away and puts the Yin Soul Bead in his mouth, the Yin Soul Bead will lock his soul in his body, and as long as he finds an opportunity, he may even have a chance to resurrect the dead.

Of course, this opportunity is not so easy to find, the soul is set at **, if you want them to combine again, you must also find a spirit grass called Melting God Grass.

This kind of thing is a kind of spiritual grass in the memory of the medicine king, or a third-level spiritual grass.

In the memory of the Medicine King, this spirit grass was not difficult to find, and even a medicinal herb for refining an elixir, as for its other function of fusing the body and soul, few people would use it.

It's not that those people don't want to use it, it's that the Yin Soul Bead is very hard to get.

Ghost cultivation is generally cultivated in the netherworld, and it is basically difficult to encounter, and luck like Li Xuedong can be described as bursting.

"Ghost Cultivator...... What is this?"

Huang Yiyan obviously didn't understand what ghost cultivation was, and Li Xuedong didn't know it at first, this was the medicine king's memory that took the initiative to give back to him, including the effect of the Yin Soul Bead.

Although it can't be used for the time being, this Yin Soul Bead must be a good thing, and Li Xuedong directly put it into the storage ring.

Originally, Li Xuedong wanted to find out if there was a golden character "Tao Te Ching" in the basement, but he didn't expect to meet a ghost cultivator, although he was a little disappointed, but getting such a good thing as the Yin Soul Bead was worth the trip.

Huang Yiyan's disappointment was written on her face, and she was very depressed that she didn't find the golden character "Tao Te Ching", so she had to follow Li Xuedong out.

After walking out of the basement, the feeling of being trapped by something disappeared in an instant.

Li Xuedong looked back at the basement, it was still pitch black, even if he opened his spiritual vision, he still couldn't see anything else.

The light of several flashlights shone in, and through the window three security guards could be seen approaching.

It is estimated that it was the report made by the young couple who were in the library before, Li Xuedong immediately grabbed Huang Yiyan's hand and quickly took him out of the library through the side door.
