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

Cui Heng had long heard of this Daoyi Palace.

This was the head of the Dao Sects in the world, and it was located at the center of the world, Mount Donghua.

The Daoyi Palace claimed to have existed for more than 10,000 years, long before the birth of this world's national system.

Moreover, they even claimed that their Ancestral Master was the head of the Heavenly Gods who had once divided the 36 states in the world and was respected as a "Dao God" by Daoyi Palace.

As for whether this was a boast, no one knew.

After all, the earliest historical records of this world could only be traced back to more than 3,000 years ago. Even if some myths and legends were included, it only dated back about 4,000 years ago.

However, what was certain was that there were already words like "Daoyi Heavenly Palace" and "Dao God" on the existing bronze artifact inscriptions of "Yan Dynasty".
