The cave of the Demon Realm refers to the sub-space realm tunnel connecting the human world and the demon world. Through this tunnel, high-level monsters in the demon world who were originally blocked can enter the human world, and can also enter the demon world.

The opening of the Realm Tunnel requires four stages. In the first stage, the miasma on earth is getting stronger and stronger, and inferior creatures in the Demon Realm breed and grow larger in the human world; in the second stage, people with special abilities appear in the human world; in the third stage, higher monsters below level D are born to the human world one after another; in the fourth stage, when the radius of the cave exceeds two kilometers, monsters of level c and level b can enter and exit freely.

For the spiritual world, the demon world is boundless and very broad, and the spiritual world manages only small parts. If the demon world is compared to an underground building with countless floors, then the scope of the spiritual world management is only half of the underground first floor.

Originally, in order to prevent powerful monsters from entering the human world, the spiritual world arranged a barrier in the subspace between the human world and the demon world, and monsters of level A and S cannot pass. According to the story of the little Hell and Yousuke's understanding, a level A monster is even more terrifying than all level B monsters.

When Mudan contacted Cheng Yun, it was only three weeks before the fourth stage, and Youzhu and others were planning to go to the insect citation market where superpowers appeared.

Since the spiritual world had already paid the money first, Cheng Yun and the others followed Youju and the others to the insect hush market. Although it was a bit embarrassing to meet Youju and Sanghara, it was fine soon.

Yousuke and others found Murota, a superpowered person who had the ability to listen to others' voices, and thus knew the person who dug the cave in the Demon Realm. However, during the search, Murota was attacked and broke his head. He had no choice but to go to the nearest hospital, but he didn't know that he had been followed by a guy named "Doctor".

However, with Murota in their hearts, they soon knew, because Murota had heard the dark heart, "Come on, someone is expanding the field, ah, I heard, it's the doctor among the seven people, he's in the hospital, and he's going to kill us."

"Youzhu, I'll leave the matter here to you. There are some interesting children outside, I'll meet them." After saying that, Cheng Yun turned around and left directly.

Not to mention that Yousuke was fighting with the doctor in this "big evil hospital", Cheng Yun had already seen Xianshui under Bai Li's leadership. Although he had just passed by, Bai Li still clearly remembered the smell of Xianshui. Xianshui and the others were watching Yousuke and the separated Zangma and others from the roof of the building.

At this time, Xianshui had already seen the Tibetan horse, Mudan and others below, "They are the remaining group of people." A young man with pink hair said, he was a "sailor".

"Everyone looks so innocent, haha." Xianshui stood beside the building, with her slender body standing straight.

Another black-haired jacket boy is Blade Mist, a super-powered guy named "Sniper", a guy who can eject the power of a bb and asks Xianshui, "What are we going to do next?"

"You don't have to do anything." Cheng Yun's voice was very sudden, which made the two teenagers tense up instantly, staring at the direction where the sound came with a cautious look on their faces.

"Who are you?" Xianshui seemed much calmer and his tone was very plain.

"It doesn't matter a bunch of people watching the show."

"Is that true?" Blade mist was about to spread wide open his left hand, and there was a colorful bb bullet in the palm of his palm. The index finger of his right hand popped out one after another, and the bb bullets were shot out one by one. The penetration was amazing and the speed was extremely fast.

Dangdangdangdangdangdang!

Almost at the same time, Cao Qiu took one step forward, and his fists and legs were blown out one after another. The martial arts and amazing power of the boxing and footwork blocked all the bullet-like bb bullets.

Then, Cao Qiu retreated as if nothing had happened. There was no trace of Cao Qiu's body. The five-star Cao Qiu had amazing defense and power that was not inferior to Dosuyuro. This kind of bb bomb could not break his skin at all.

"Young people, be calm and impatient. Those who are as impatient as you want to do something like destroying the world? Joke, you can die!"

Before he finished speaking, a scarlet light flashed in Cheng Yun's eyes, like two wiping sword lights, bringing the harvest of the god of death, and cutting the blade fog into three sections at once.

This kind of attack seems magical, but in fact it is just Cheng Yun's new application of killing power. He integrates murderous intent into his eyes and releases it through his eyes. When the blade fog wants to see Cheng Yun, it is actually attacked by strong murderous intent. However, the murderous intent at this time is completely restrained, just like an ordinary gaze, without any sense of threat.

When Cheng Yun had a murderous thought, the invisible killing blade immediately appeared. The scarlet murderous aura was the killing aura accumulated by Cheng Yun over the years. The killing aura at the demigod level already had the same ability as the god of death, destroying life and spreading death.

"You..." The sailor shouted immediately when he saw his companion die suddenly, but before he finished speaking, he was stopped by Cheng Yun's gaze with a smile.

"Destroying the world is not suitable for you. Just go home honestly and wait for the results."

The sailor's mind was confused, and a sound that seemed very familiar and infatuated sounded in his ears. The sound told him that he should go home, so the sailor said "Oh" and turned around and left in a daze.

"You are Qiu Yue Chengyun? What's wrong with coming here? If it's okay, I'll leave first."

Cheng Yun was not surprised that Xianshui knew his pseudonym. After all, he was also a person who could show off his skills in Dark Martial Arts. Xianshui, as a guy who had been wandering in the dark world for a long time, had his own extraordinary experience.

"Brother Xianshui, don't rush to leave."

"Why, you want to keep me?"

"no!no!no! I'm just a little interested in what Brother Xianshui is doing. No, I should say I'm very interested."

"Hmph, is that right? Are you interested in eliminating humans?"

"Eliminate humans? No, your idea is too narrow. I want to do much noble. Although humans have fallen, the monsters and demons are not good. The depravity of life comes from the turbidity of the world. It is useless to simply destroy a race. If you want to do it, just return the entire world to the original state, completely purify the entire world, and then I will create an ideal new world."

"You~~"

"How is it? Brother Xianshui, there are only like-minded people in this world who may be like-minded with me. You are the closest one. Do you want to join? Think about it carefully, goodbye!" After saying that, Cheng Yun and others left with Cao Qiu, who was already a little dull.

"Oh, by the way, I'll send you a message before leaving. The friend named Suzuka, Kazumaki, is a person with the ability to tear the dimensions, and you should know how to use it."

"Why tell me this?"
