Yunyang City is close to the Zixiao Mountain Range, and it is not far from the Zixiao Sect, and it only takes a few hours to reach it at the speed of Thunder Feather, which is quite convenient.

When Lei Yu came to Yunyang City, it was already late, but Yunyang City was still lively, and it had not changed in the slightest because of the arrival of night.

The tall city wall surrounds Yunyang City, which is more than ten zhang high, and all of them are paved with green bricks, which is very strong. This is a big city, with a population of one million, and it is also famous in Yunzhou, with people coming and going, and it is very lively.

The buildings in the city are lined up one after another, especially prosperous, and the flow of people is dense. It's getting late, but it's just the beginning of the night. Lights are lit up everywhere in the building, as if it were daylight, without the slightest impact.

The shouting and shouting came and went, and Lei Yu blended into it, but it felt a little like a world away. Regardless of the small village where he lived before, or when he came to the Zixiao Sect, Lei Yu had never seen such a scene, and he was a little surprised, and wandered around the streets.

"There is indeed a human atmosphere. Lei Yu walked around for a while, looked for a restaurant and tea shop, ordered a few dishes, and drank by himself, which was a lot of fun.

Looking at the crowd downstairs, Lei Yu's divine thoughts spread out, checking if there were any signs of demons. According to what the scroll says, this demon was a casual cultivator before, but he went crazy because he went crazy, so that people don't look like people and ghosts, and he committed crimes near Yunyang City, and many mortals have been taken captive by demons.

"It seems that this demon will not appear in such a place. Lei Yu observed for a long time, but found nothing.

There are thousands of kinds of thunder methods, countless of them, there are infinite thunder methods, and some of them are fused with demonic qi to form a unique magic thunder, which is very ruthless. And these cultivators who cultivate demon thunder are called demon cultivators. The biggest difference between the magic thunder and other thunder methods is that it is born with masculine thunder, and it is very serious, like this kind of crowded place, the more yang energy is also more abundant, and it rarely appears in this kind of place.

Lei Yu thought for a moment and decided to leave here. He opened the scroll, which contained detailed information about the demons.

"The most common occurrence of demons is in the dense forests to the east, and I'm afraid I'm going to look for them in that dense forest. Lei Yu made up his mind, left the restaurant and tea shop, and walked towards the outside of the city. Inside the city, he didn't dare to behave abnormally, but outside the city, he used his thunder power to his feet, and the wind was under his feet, and he arrived at the dense forest in the east in less than half an hour.

It was dark and some couldn't see clearly. Occasionally, a gust of wind blew, and a rustling sound sounded in the dense forest, but it added to the silence. Here, Lei Yu felt a yin aura surrounding, a little cold, and unconsciously wrapped his clothes.

"This place seems to be very close to the Nether Forest. Lei Yu looked around. He was already a fourth-order Thunder Qi cultivator, and he was able to see in the dark without the slightest hindrance.

He looked around carefully, but his heart was a little nervous. There is something unusual here, the yin qi is long, and it is an excellent place to cultivate the demon thunder. Lei Yu estimated that if he went inside, he was afraid that he would encounter some ghosts and ghosts.

The yin wind was howling, and a yin fire rose in the depths of the dense forest, which was a little terrifying. Lei Yu only felt that his scalp was a little numb, and his mind swept towards the place of yin and fire. The white yin fire was very conspicuous, and Lei Yu's divine thoughts swept away, but he saw a dry bone burning, and the yin qi around it gathered to form a mysterious scene.

"Ghost fire!" Lei Yu let out a long breath and suppressed the tension in his heart.

Ghost fire is still a mortal fire in the final analysis, and there is no need to be afraid of it with his cultivation like this. It's just that a dry bone was found in the depths of this dense forest, which still made Lei Yu frightened, and he didn't know what kind of scene it would be to go inside.

Lei Yu carefully glanced around with his divine thoughts, with his current cultivation, the range of divine thoughts was a hundred zhang away. As long as it is within the range of 100 zhang, any wind and grass and quiet thunder feather can be detected.

Without detecting any danger, Lei Yu once again headed towards the interior of the dense forest. The dense forest is heavy, the trees cover the sky, and the sun is not seen all year round, and occasionally there are one or two howls of wild beasts, which makes Lei Yu's heart tense. When he walked about a hundred zhang or so into the depths of the dense forest, Lei Yu had already killed several fierce beasts, and blood flowed all over the ground.

Lei Yu stopped, his location was overgrown with weeds and difficult to spot. His mind scanned the front seriously, there seemed to be a sound in the dense forest just now, and he needed to listen carefully again.

"That voice just now seems to be not far from here, it seems to be a kind of beast roaring sound, let me see what the hell is going on?"

"Huhu ......" A wheezing sound clearly came into Lei Yu's ears, and there was a beast's breath contained in it. When Lei Yu heard it, he thought that this sound was the sound of a fierce beast, but after listening closely, he found that it was different, as if this sound had the taste of a human wheezing.

"Thirty feet ahead, go and see. Lei Yu frowned slightly, sneaking secretly. Combined with the information on the scroll, Lei Yu can roughly determine that it is the demon he wants to kill on this mission.

Lei Yu slowly touched in, without making the slightest sound. He slowly approached, and the voice grew closer, clearer and clearer. When Lei Yu came to the place that was only about ten feet away from the sound, the scene in front of him shocked him.

A human dressed in black was frantically sucking the blood of a human lying on the ground, and beside him there were several human corpses lying on the ground, apparently dead.

The human had the smell of a beast, and the smell of blood was strong all over his body. He bit the neck of the man lying on the ground hard, and bright red blood gushed out and flowed into the body of the man in black. Lei Yu felt it carefully, but there was a magic power brewing, he was cultivating, cultivating with human blood.

"This is the Majin. Lei Yu had already determined that the human in front of him was a demon, and he opened his eyes and observed carefully. At the same time, he mobilized the thunder power in his body to kill with one blow.

"Roar!" a beastly roar came from the demon's mouth, and he seemed to have spotted Thunder Feather, stopped sucking Yun's blood, and turned his head to look in the direction of Thunder Feather. Suddenly, an extremely ugly-looking human appeared in front of Lei Yu.

What kind of man is this? His hair was disheveled, his face was rotten, and a scar stretched from his skull to his chin, making him look extremely ugly. And the corners of his mouth were still stained with human blood, and the beastly aura was unmistakable. He's not a man anymore, he's just a beast.

The fierce eyes were staring at Lei Yu, without the slightest human reason, full of ferocity, as if the Lei Yu in front of him was just his mouth.

"Hmph, suffer death!" Lei Yu snorted coldly, since he was discovered, he wanted to kill the demon with the overwhelming force of thunder, and he couldn't let the demon have the slightest chance.

The right hand stretched out, and a piece of blue light appeared on the right hand, containing great power.

Aoki Thunder Fist!

The right hand blasted out, and Aoki's thunder fist surged towards the demon. At this time, the Aoki Thunder Fist is not the same as before, with the improvement of Lei Yu's strength, the power of Aoki Thunder Fist has also greatly improved, according to Lei Yu's estimate, this blow is enough to kill the demon, and it will also seriously injure him if it is not good.

Aoki's thunder came rolling in, like a cyan sharp knife piercing the demon in the center, which made the demon a little panicked.

"Smack!" The demon raised the corpses around him and threw them at the Aoki Thunder Fist, hoping to counteract the momentum of the Aoki Thunder Fist.

The cold corpse was already bloodless, without the slightest breath of life, and it was thrown at Lei Yu in a daze. Lei Yu's gaze did not waver in the slightest, at this moment his target was that demon man, no matter what was in front of him, nothing could stop him.

"Boom!" a punch blasted out and hit the corpse, and in an instant, the corpse was torn apart and fell to all sides. I don't know where the head, body, hands and feet have fallen, but there is not much blood flowing out, and it is all absorbed by the demons.

Lei Yu did not stop in the slightest, his body moved forward quickly, and Aoki Thunder Fist became more powerful. The cyan glow is extraordinarily dazzling. The power of this punch can also be felt by the demons, and although he has lost his mind, this most basic instinct still exists.

A panicked look flashed in his eyes, and he threw all the corpses around him at Lei Yu. It's just that it doesn't have the slightest effect, and the stump and broken body are flying in the sky, which is extremely weird, but Lei Yu has no effect, and his eyes are still focused on the demon.

"Die!" Lei Yu was very calm, and Aoki Thunder Fist bombarded the demon's body, and suddenly a depression appeared on the demon's body, several inches deep. He screamed miserably, and was knocked ten feet away by the force of Aoki's Thunder Fist.

"Poof!" the Mato spurted out a mouthful of blood, his face a little pale. It's just that at this time, his face was fierce, like a trapped beast. His eyes gradually turned red, and the human aura on his body gradually degenerated, and he was gradually enveloped by a strong beastly aura.

Lei Yu was cautious, the blow of Aoki's Thunder Fist did not kill the demon, and it seemed that there were some incredible changes in the demon's body, at least Lei Yu could feel that the thunder power in his body was constantly increasing, and there seemed to be signs of further breakthroughs.
