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 Juntian as the name, it should be a palace that Zhou Juntian valued.

Cui Heng sized up the palace with a focused expression.

He felt an ancient charm from it. This was an aura that had been accumulated for countless years, making one involuntarily sigh with emotion.

Just being able to exist in the Earth Fire for hundreds of thousands of years was enough for it to obtain a qualitative sublimation.

In addition, Cui Heng also sensed extremely exquisite traces of Dharmas and Logos on this palace.

This meant that the cultivation realm of the person who created the Juntian Palace was extremely high. Moreover, he was very good at using laws and principles and could perfectly fuse these laws and principles into the palace.

Even cultivators at the Grand Completion Golden Core Realm could not do such a thing.

One had to at least be at the Early-stage Nascent Soul realm to be able to do this.
