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

At this moment, Chu Feixiao thought that he had heard wrongly.

How could such an expert who could easily crush him be related to Hongwu?

That was just an outsider with no foundation.

Could it be that the expert in front of him was also an expert from outside the Immortal Land?

However, shouldn't it be a wilderness outside the Immortal Land? It was extremely backward. Even the cultivation system was incomplete!

For a moment, many thoughts flashed through his mind, and he actually did not know how to answer Cui Heng.

Cui Heng naturally sensed his chaotic thoughts, so he grabbed him and flew into the sky, arriving at the huge war chariot parked on the clouds.

The nine dragon-shaped mixed-blood ferocious beasts pulling the chariot immediately flew into a rage when they saw this. They roared angrily and attacked Cui Heng.
