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

A deafening voice spread throughout the chaotic void, causing everyone present to feel as if they had been struck by lightning. They could not help but look at this huge figure.

His arrival was without warning. Even Cui Heng did not sense it in advance. There were no signs of his appearance at all, and there was no abnormality in this chaotic void. It was as if he had appeared out of thin air.

It was very mysterious and abnormal.

In Cui Heng's perception, this huge figure did not enter from outside, nor was he originally hidden here. There were actually no traces to follow.

It was as if he had suddenly appeared here from another space-time dimension.

This was a situation he had never seen before.

If he had to analyze it, it was a little like the situation when a new fake self was born.

Moreover, it was some kind of fake self born from legends or stories.

There was no actual source, and it appeared out of thin air.
