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

With an uneasy heart, Lian Heng, Qin Tang, and the others followed the Yellow-scarved Strongman into the palace and saw Cui Heng drinking tea.

At this moment, they understood that the person in front of them was definitely not the former Lord of the Heavenly Court.

That was because even the aura on the Lord of the Heavenly Court was far from being so vast. It was as if it contained everything.

What kind of cultivation realm could be so powerful?

Could it be that there was really a realm that surpassed the 12 Heaven Gate realms?

Facing such an unfathomable expert, these Sect Masters of the Immortal Dao Sects who were usually high and mighty were all deeply shocked. They only stood there with stagnant gazes and even forgot to bow.

After a while, the Heaven Gate realm experts, led by Lian Heng and Qin Tang, came back to their senses and hurriedly bowed.

"Eternal Academy's Lian Heng greets Senior."
