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

These scenes seemed to have all gathered together, condensing into a strange ball of light that looked both like a colorful spot and completely colorless. It floated in the air. Cui Heng hesitated for a moment before revealing a trace of Dharmic powers to come into contact with this strange ball of light.

Then, the ball of light changed again and turned into a palm-sized solar system model that kept spinning in the void.

When the trace of Dharmic powers Cui Heng released was exhausted, the miniature solar system disappeared and returned to the appearance of a strange ball of light.

However, although it was only a short change, it allowed him to figure out what this ball of light was and what its use was.

"Rather than calling it a passage, it's more like a space-time road sign." Cui Heng thought to himself, "This light ball is actually the imprint of the solar system at a certain time. Through it, one can descend to the solar system at this time.
