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

In this era, the Supreme Gods of Heaven and Earth had already been expelled from the Primordial World. Who else could make the Supreme God of man fall into such a state of immobility? "Or is it that the history of creation that I know is not complete and is fake?" Cui Heng thought to himself, feeling very puzzled.

At this moment, Huang Yun explained, "With our strength, it's naturally impossible for us to suppress the Supreme God of Man. However, ever since the Supreme Gods of Heaven and Earth were expelled, the Supreme God of Man has fallen into a strange state.

He often fell asleep. At first, he slept for 10,000 years, but later on, the time became longer and longer. In the recent tens of millions of years, he only woke up for a short hundred years.

We also discovered that when the Supreme God of Man fell asleep, it was as if he had become a powerless living being. He was no different from an ordinary person and was simply unable to withstand a single blow.
