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

"Why do you suspect that this person is a Human Immortal from an Immortal sect?" Tang Huaiyi asked.

"Tell me how you discovered this Human Immortal, what you did, and where that Human Immortal is now," Song Zhong added.

Although the two of them were only Human Immortals and had only reached the Human Immortal Realm after consuming the Human Origin Immortal Pill and were relatively weak, they had already obtained the support of Hui Shi's True Essence and could unleash strength close to that of an Earth Immortal in a short period of time. Naturally, they were extremely confident.

They already had the confidence to resolve any trouble at the Human Immortal realm.

"Reporting to the two Immortals, it's like this…" Wang Qian hurriedly explained what he had seen and sensed with his divine power to Tang and Song, then told them some of his guesses.
