Sole Cloud Flying Cave

Cui Heng was transmigrated to another world and the system told him that the new world he was in was a high-grade Xianxia world.
It was a world where Celestial Kings soared the sky and terrifying monsters ruled the lands. The strong would destroy a planet if their mood was bad and Cui Heng trembled in fear when he learned of how scary the new world was.
Thankfully, the system had granted him the protection that last for 300 years. As long as he remained in the safety zone, he would not receive any damage.
With his safety secured, he began his cultivation training for the next 300 years.
Throughout the years as he trained, some people entered his safety zone by mistake.
There was a peasant who was once a monk and a beggar. Despite that, he still had the dream of bringing peace to the land and saving the lives of millions.
There was a noble who was once called the once-in-a-million-year genius. Yet, luck wasn't at his side and his talent fell and was laughed at by others for years.
There was a princess whose only wish was to find her older brother. She could've become a celestial but decided to remain in the human realm to wait for her brother's return.
There was a weak lady who was plagued with illness from birth but had the goal of adventuring and helping the poor and weak.
...
Cui Heng befriended these people and even gave them a few pointers before they left.
300 years later, when the protection period had ended, he had finally mastered the Golden Core. Even then, he was still reluctant to go to the outside world.
But when he did, he realized that the world was merely a world of Wuxia.

Realizing This Is A Wuxia World After Cultivating For 300 Years

"…" Jin Ding was speechless. He looked at the young man and said in a low voice, "You will be punished to solitary confinement in the dungeon for 10,000 years. After 10,000 years, if you can't figure out what you've done wrong, you will sit there for another 10,000 years." "Ah?" The young man looked stunned and his eyes widened, but he no longer had the chance to ask why.

Cui Heng, who was at the Peak Soul Formation realm, was everywhere and could exist in many places at the same time.

Therefore, Cui Heng, who had left the secret world, directly went to an Immortal land formed by the fragments of a High Heaven Immortal Domain through the Six Heaven Gates Diagram.

At the same time, countless fake se;ves headed to similar Immortal Lands.

These Immortal Lands were the same as the Immortal Land that Tian Qing was in. Their essence was extremely high, and the laws of the Immortal Domains were extremely dense.
