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 did not know much about Taihong Star.

The first time he heard of Taihong Star was when he saw Hong Fugui's message in the Heavenly Void World. He only knew that it was a planet a Great Divine Being.

Later on, when he saw Heavenly Saint Supreme Venerate, he further understood the situation of Taihong Star.

However, the Taihong Star described by Heavenly Saint Supreme Venerate was not very powerful.

Heavenly Saint Supreme Venerate's father, Divine Lord Tianhe, had passed by Taihong Star on the way to Daozhou Star with the Dao God.

At that time, everyone, including the Dao God, took a group of people from the Living Star as their initial team.

This was also the origin of the Ten Immortal Sects of the Heavenly Void World.

That was 10,000 years ago. Back then, the Dao God was only a Limitless Golden Immortal, and the people accompanying him were only at the Golden Immortal realm.
