At first, Lin Jin thought that he had been discovered, but he did not dare move an inch.

But when he looked into the eyes of the Black Freak, Lin Jin realized that he had worried for nothing.

It was because the Black Freak's eyes did not open. From the location of the eyes, Lin Jin saw two balls of black gas s that were so thick that they were like two black gems covering his eyelids, emitting waves after waves of cold light. No wonder Lin Jin thought that he had seen himself.

However, seeing his appearance, Lin Jin was still shocked. With a glance, it was as if all the muscles on his face had shriveled up, leaving only a layer of skin on top of his face.

However, there was a handsome, straight nose on his face. It was incomparable to his current appearance, making him look extremely strange.

Although the Black Freak's spinning speed was not fast, it was not slow either. Lin Jin had just sized up the Black Freak when he spun around, only to see a long caped monster dancing in the air.

The Black Freak spun a few more rounds, and then, as if the song had reached its end, the voice coming out of his mouth became louder and louder. Every tone was much higher than the previous one, and it was definitely not inferior to the high pitch when Pavarotti sang the high note C.

As time passed, his high-pitched voice echoed throughout the prison. It was loud like the sound of metal clanging. However, there was a sense of evilness coming from it that made people feel suffocated.

As for the black gas that were spinning downstairs, they kept increasing their speed as they sang. With a swooshing sound, the mountain rose to a height of nearly ten meters.

Speaking of which, if this Black Freak could produce such a low pitched voice, if he walked onto the international stage, it would definitely make all the people who liked opera go crazy. Unfortunately, in the entire prison, the only person who could hear his voice awake was Lin Jin, the only person who could hide at the side and peep but did not know how to enjoy the music.

When the tune reached an extremely high pitch. Abruptly, Lin Jin saw a cold light flash in front of him, and that person abruptly opened his eyes, falling down from mid-air.

Seeing that, Lin Jin immediately retracted his head and hid.

The singing suddenly stopped, and the entire space seemed to emit a buzzing sound. Even the rotating black gas was also shaking. It showed the power of the last note he hummed.

Once again, Lin Jin peeked his head out to peek, only to see Black Freak holding a five foot long pure black flag. He drew circles on his head in a mysterious way, constantly drawing circles.

And those black gas downstairs, followed the movements of the flag in his hand. He kept throwing them into the circle his banner had made, forming a dark vortex three feet above his head.

Seeing his actions, Lin Jin unconsciously frowned. He could completely feel that as the number of black gas in the circle increased. An overwhelming sense of oppression gradually spread out from the circle.

The Black Freak seemed to be struggling to dance. Although he could not read much from his expression, the speed at which he was waving the flag became slower and slower, as if he was stirring up a ball of extremely viscous mud.

Seeing that his expression became extremely heavy, Lin Jin knew that this spell had reached a critical juncture. He guessed that he definitely did not have the ability to pay attention to the situation in the outside world at this time, and immediately activated his zhenqi. He used a defensive spell that was recorded in the book as a precaution.

As he cast the spell, some of the surrounding spiritual energy was attracted by him, forming a strong layer of air around his body.

Because of this technique, the black gas downstairs also fluctuated. The Black Freak seemed to have detected something and the flag that was waving slightly paused for a moment, as he scanned his surroundings vigilantly.

But whether it was because Black Freak used up too much energy, or because of Lin Jin's invisibility, that Black Freak felt that it was a little strange. However, no one had noticed his existence. He only glanced at his surroundings and then continued waving the flagpole.

Seeing that all the black gas downstairs had thrown themselves into the small circle above Black Freak's head, Lin Jin did not know what to do either. After all, he didn't even know what spell this person was currently casting. He didn't know if it was good or bad.

Naturally, there was no reason to stop or destroy it.

Half an hour later, the last bit of black gas finally entered the small circle.

Lin Jin didn't know when this spell would be activated, and looking at the situation on the other side of the stairs, he didn't dare to be distracted at all.

When the Black Freak saw that all the black gas had been pulled into the whirlpool, he heaved a sigh of relief and quickly waved the flag a few times.

Streams of black Qi streaked across the sky, immediately forming a mysterious pattern that wrapped around the vortex formed by the yin evil qi.

After a while, the black Qi tornado in the air gradually became smoother, like a black basketball. However, the occasional aura that emitted from it made Lin Jin, the person who was about to enter the Large Circulation, feel a sense of fear.

With so many yin evil qi gathered in one ball, he dared not imagine what would happen if it exploded.

However, the Black Freak's technique was not finished yet. When the black ball was formed, he took out a pill from his bosom and threw it into his mouth, then suddenly sat down on the ground and recovered his luck.

However, it seemed that his method this time had consumed too much spirit and zhenyuan, and swallowing the pills did not seem to have the desired effect. When he stood up, his body was even a little unsteady, and he swayed a few times.

Next, he touched his waist, and another white flag appeared in his hand, waving about.

Aside from the color, the rest of the flag looked exactly like the black flag. It seemed like it belonged to a magic treasure.

This time, the Black Freak did not even sing a song. Instead, he just weirdly said the six words "Om, Om, Mi, Roar" from his mouth and lightly waved the flag pole.

Lin Jin felt that it was very strange, this black clothed man was obviously a monk like the Demonic Cultivator, why did he have to chant the Buddhist incantation?

Before he could understand what was going on, he saw streams of white smoke coming out from the building and spreading to the whole prison.

Seeing this white gas, Lin Jin couldn't help but be shocked.

The black gas was formed from the resentment of the yin evil qi and the dead, but what was this white gas?
