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

"It's you?!" Feng Guanglin looked at Cui Heng in disbelief and said in shock, "You're here too?!"

"The two people you want to invite are my disciple and my servant." Cui Heng nodded lightly. "Where's the Yellow-scarved Strongman?"

The Yellow-scarved Strongman appeared out of thin air and descended from the sky. He landed at the side and bowed to Cui Heng. "Greetings, Immortal Venerable!"

"You, you, you're a Dao Lord?!" Feng Guanglin looked at Cui Heng in extreme fear and muttered, "How can there be a Dao Lord in the starry skies of the myriad worlds? How can there be a Dao Lord?"

A Dao Lord was a martial artist at the peak of the Seventh Realm with a perfected Dao Body. He could use the power of certain laws more deeply.

In his opinion, the reason why he lost his strength just now and seemed to have become an ordinary person was probably because he was affected by some strange Dao Body nomological power.
