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

The place where the Princess of the Wood Nation gathered the experts was called the Heroes' Pavilion.

This was originally the place where the previous Emperors of the Wood Nation recruited talents. Under normal circumstances, it would not be opened.

However, there were too many experts from all over the world this time.

Most of them had the strength of the Peak of the Shaman Marking Realm. There were even some who had already begun to carve their Dao Imprint and were only one step away from the Divine Body Realm.

Moreover, they were basically from the large factions in the Green Stone Wasteland. There were even experts from the core area of the Qinghua Domain.

These people were extraordinary in strength and had very powerful backgrounds. It was very difficult to settle them down properly, so they could only open the Heroes' Pavilion and gather many experts. Then, the Princess of the Wood Kingdom appeared and gave them an answer.
