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 southern part of Lu County had always been a place of wealth. Large residences were gathered there.

Sun Panshi had long bought a mansion here as a temporary residence. He had also recruited hundreds of servants and taught them martial cultivation.

On the surface, they were training the outer sect disciples of the Taichong Sect. But in reality, they were raising private soldiers.

Other sects like the Heavenly Sword Sect, Green Jade Monastery, and the Dharma Monastery also had similar methods.

After all, there were too many accidents in this chaotic world. Only by possessing enough martial strength could one protect themselves.

300 to 500 servants who knew martial arts and had learned some formations and were equipped with superior weapons were enough to defeat thousands of soldiers who lacked clothes and food.
