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

"Teacher, you know this old man?" Hong Fugui asked in surprise.

"I suppose." Cui Heng nodded and asked in a low voice, "Do you know the name Zhou Juntian?"

"Zhou Juntian?" Hong Fugui was stunned when he heard that. He said in confusion, "I heard from Hong Ci that he was the last Ascender before the Purple Sun Heaven collapsed. Is this old man related to him?"

"…" Cui Heng was also stunned. Hong Fugui's understanding of Zhou Juntian was really a little "ancient", so he shook his head gently. "This old man is Zhou Juntian."

Then, he briefly introduced Zhou Juntian.

"So it's the artifact spirit of the Six Heaven Gates Diagram. But why did he guide me?" Hong Fugui frowned even more when he heard this and said to Cui Heng, "Teacher, I have news about him here."

"What news?" Cui Heng asked in surprise. From the looks of it, Hong Fugui did not understand Zhou Juntian, but he seemed to have heard of the Six Heaven Gates Diagram.
