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

Although this Saintess was only a projection of the Holy Mother of White Lotus, she was still a true living being. When facing death, she naturally had the desire to live.

Now, she had no time to think about why Cui Heng was so powerful and why the array formation and divine weapons she had carefully prepared could not even withstand a single blow.

At this moment, she only wanted to live.

Her desire to live overwhelmed everything. She shouted at the top of her lungs and tried her best to ask for help. She really wanted to obtain help before her body and soul completely collapsed.

Actually, when the Saintess' body and soul began to collapse, the Holy Mother of White Lotus had already sensed it.

In the void, where billions of Great Dao gathered and endless laws gathered, in the center of a pure white sea of light, a slender female figure slowly stood up.
