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

Sun Guangzhao's eyes widened as he looked at the incomparably huge figure in horror. He felt that he was dreaming. "What is this? What is this?!"

An indescribable fear had completely filled his heart.

He did not believe Cui Heng's words at all.

When he was in the Five Views Realm, he had also seen Star Gods who had grown to the level of Sages. However, compared to this mighty existence in front of him, they were as weak as infants.

At this moment, Sun Guangzhao only wanted to escape from this place as quickly as possible and as far away as possible. He definitely did not want to face such a terrifying existence.

What a joke. He had never heard of ants besieging ancient ferocious beasts!

However, when he was about to escape, he realized that his soul and will were suppressed by an invisible force, as if the weight of a star was pressing down on him.
