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

The actions of these two Demon Lords stunned the other six Demon Lords. They hurriedly followed suit, and their requirements were each lower than the other.

"Exalted Immortal, my main body is the Purple Qi Longevity Flower. I don't want to acknowledge you as my master. I just want to be a potted plant beside you so that you can enjoy it."

"Exalted Immortal, my main body is a Black Tortoise…"

"Exalted Immortal, my main body is a Divine Tree. My branches and leaves have the ability to connect to all worlds. I'm willing to offer my main body to you as a material for refining treasures. I only hope that Exalted Immortal can leave my soul alive."

Each of them was more ruthless than the other. The most ruthless one even wanted to use his main body as a bargaining chip.

After Cui Heng heard the promises of these Demon Lords, he could not help but be a little stunned.
