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's perception slowly enveloped the two balls of divine power left behind by the Supreme God of Man and began to analyze and explore them in detail.

One of the balls of light came from the dead Immortal Ancestor Zongmu. This was very clear.

The origin of the other ball was unknown. He only knew that it had crossed space and landed on Zhou Xuan, but he did not know where it came from.

However, Cui Heng obtained an answer after analyzing it.

It was actually the remnant energy from the creation of the two Gate Master Immortal Emperors.

Originally, this was one of the three gifts that the Supreme God of Man wanted to leave behind for the ordinary living beings. Later on, it landed in the hands of the Immortal Ancestors and was used by them to carry out a series of experiments.

The two Gate Master Immortal Emperors were only one of their creations.
