In a Tongmyeongdong mansion, two figures sit opposite each other at a stone table.

"Brother Xi, let's say, what are you coming to Xuanmen for? won't you just let Tian'er come to worship me as a teacher?" Yu Yan looked at the handsome man in cloth on the other side and asked with a smile.

"It seems that you can't hide anything from Brother Yu!"

Xi Xi smiled, then picked up a teacup on the table and drank it all, moistened his throat and said, "Brother Yu, now that the demon has been born, what can you do?"

Yu Yan was stunned for a moment, a trace of puzzlement flashed in his eyes, and then he seemed to think of something again, he was suddenly startled, looked at Xi Xi, and even asked, "Is there anything Brother Xi can do?"

"There is no way, but I can try my best to reduce the casualties of the human race, but in the face of absolute strength, it is not a cure for the symptoms after all. Xixi said.

Yu Yan raised his eyebrows slightly, and a trace of solemnity flashed in his eyes.

Indeed, in the face of absolute strength, any solution is like a fictitious thing.

"Then tell me what you can do to minimize casualties. Yu Yan asked again.

"There is only one way, set up a formation. Xi Xi paused before speaking.

Yu Yan was taken aback, "But there are so many of our human races, what kind of formation should we set up?"

As soon as Xi Xi heard Yu Yan's words, he couldn't help but glance at him, "The devil has always thought highly of himself, especially the demon ancestor, he can't kill the human race slowly, if my guess is right, the first thing he will kill is your Xuanmen." ”

Yu Yan's face changed slightly, and a thought flashed in his eyes, Xixi's words were not unreasonable.

"So, what if you just set up a formation in the Xuanmen?" Yu Yan asked.

"Not bad. I know a little bit about formation since I was a child, so leave this matter to me!" Xixi said.

Yu Yan was stunned for a moment, looking at Xi Xi with a strange expression, he didn't expect Xi Xi to know the formation.

"There's no fuss, the Yunhua Village where you lived before was actually set up by me as well, and because of this, those demon immortals couldn't detect our breath. Xixi then said indifferently.

Yu Yan's face changed slightly, and he looked at Xi Xi with a shocked expression, "Then why can't I sense it before?"

"This is the wonderful, if you feel it, then the young man in black will immediately kill Yunhua Village. Xixi smiled disappreciatively.

Yu Yan was suddenly surprised, but at this time, he also discovered that Xixi was so unfathomable, in addition to his superb medical skills, he was also proficient in formations.

How much else is there to this guy that I don't know?

Looking at the handsome young man in front of him, Yu Yan said secretly in his heart, and then said: "Without further ado, then let's hurry up!"

"Don't worry, let's have a few cups of tea first. Xi Xi smiled.

"......" in the end.

Time flies, and three days have passed since Xixi and Xitian came to Xuanmen.

This day, early in the morning.

In a gloomy cave mansion, I saw a white-clothed figure sitting cross-legged in the center of the cave mansion, exuding an invisible sword aura from his body.

Each of these sword qi exuded a terrifying might, and gradually, these invisible sword qi gradually turned purple.

Ten purple sword qi were formed in an instant, and these ten purple sword qi cut through the space, emitting a 'snort!' sound.

Drink!

After a loud shout, a dazzling purple pillar of light, in an instant, burst out from the body of the man in white, broke through the top of the mountain, and went straight to the sky.

The elders and disciples of the Xuanmen who were still in retreat and cultivation were all shocked, and there was a look of horror in their eyes.

Brush Brush Pair!

The crisp sound of breaking the sky resounded throughout the Xuanmen, and many disciples and elders of the Xuanmen couldn't help but follow the prestige, looking at the dazzling purple pillar of light, their eyes were full of shock.

"What is this?!"

"What a terrifying might, such a domineering sword intent.

”

"This, could it be that the sect master has broken through the sword path?"

"The Mystery of the Sword!"

All the people in the Xuanmen were surprised, and the surprise was full of doubts, who is it?

Of course, people like Zhu Budo, Bai Tu, and Hua Lao naturally knew who sent out that pillar of light, because it was no one else who lived there, it was the cave where Yu Gan, the master of the Xuanmen Gate, was located.

In a modest house, the wooden door squeaked!' and it opened. Then, I saw a handsome young man in cloth walking out of the wooden house, looking at the purple pillar of light that soared into the sky, the young man smiled slightly, "I didn't expect Brother Yu's sword path to break through so quickly, it seems that the sky will not die in my human race!"

The young man laughed, turned around, and walked into the cabin again.

At the same time, on a flat ground in the outer gate of the Xuanmen.

The two figures also raised their heads at the same time, looking at the dazzling purple pillar of light that reached the sky, their eyes full of shock.

"This is the mystery of the sword, the mystery of the terrifying sword!" exclaimed a middle-aged man in black with a broken arm.

"Yes, the one who can exude such a powerful sword intent is Lord Yu?!" a young man in cloth also said, a trace of doubt flashed in his eyes as he spoke.

The two of them are none other than Cliff and Wang Song!

The two originally had nothing to do with each other, but as the two most outstanding disciples of the Xuanmen Outer Gate, they naturally knew each other.

Although there is a lot of difference in the age of the people, but the two hit it off at first sight, and they became friends in an instant, no, the two were originally cultivating on the flat ground, but looking at the dazzling purple pillar of light, they were shocked for a while.

"Brother Broken, did you say that terrifying sword mystery was emanated by Lord Yu?" Wang Song looked at the black-clothed young man with a broken arm next to him and couldn't help asking.

"I don't know!" Cliff shook his head slightly, then looked at Wang Song, and said with a smile, "Xiao Song, with the swordsmanship talent of adults, it must not be much worse than it. ”

The two spoke, but there was a hint of anticipation and excitement in their eyes.

It turned out that at this moment, they didn't know that the dazzling purple pillar of light was emitted by Gan, so they didn't know that Yu Gan was the master of the Xuanmen.

In the Xuanmen, the purple pillar of light broke through the sky, and the crisp sound of breaking the sky also resounded from the pillar of light throughout the human realm.

"Look, what's that!"

"What a terrifying sword intent, this is bursting out from the direction of the Xuanmen, could it be that another powerful figure has appeared in the Xuanmen?"

"Just listening to this sound of breaking the sky makes my body and mind tremble!"

At this moment, all the monks in the human domain couldn't help but look up at the dazzling purple pillar of light, their eyes full of horror.

And the Demon Immortal Domain, a large hall that exudes an evil aura.

The space in the hall distorted, and then a black figure emerged from nothingness.

As soon as the black figure appeared, it sat down in the seat above it, and the whole space 'buzzed!'.

Strangely, the black figure was not an entity, but a human form formed by the condensation of black gas.

Although this is not an entity, the aura it exudes is no weaker than Yu Qian, and this black humanoid is none other than the ancestor of the demon immortal clan!

"Interesting, I wanted you to live a few more days, but it looks like I'm going to have to change my mind. ”

Only a deep, evil voice was heard, coming from the black human form.
