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 Heart Nourishing Courtyard was built 70 years ago.

At that time, under Pei Qingshu's lead, the Linjiang Pei family had completely separated from the 24 aristocratic families.

They also began to cooperate closely with the Great Zhou Imperial Family and Daoyi Palace.

They were no longer suppressed by the Immortal Sects.

From then on, Pei Qingshu's reputation in the Pei family was like the sun at high noon. He gradually became the backbone of the entire family and the core of the entire family.

The entire Pei family seemed to be developing to a new height.

However, Pei Qingshu knew very well that this was only on the surface. The strength of the Immortal sects was far from what he could compare to.

If not for that person from Daoyi Palace, adding on to the fact that the Nine Elders of the Immortal sects had some problems, he and the person from the Great Zhou Imperial Palace alone would not be enough to resist the nine Immortal sects.
