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

Now that Shen Lou had brought people to sit around Hong Fugui, it naturally made more people look at Hong Fugui, wanting to see what was so special about this "young man" that Shen Lou actually valued him so much. After Shen Lou sat for a while and saw more and more people gathering around, he became even calmer in his heart. The expression on his face was almost completely normal. He smiled and asked, "How should I address you?"

"Just call me Hongwu." Hong Fugui nodded slightly and smiled. "You're the head of the Eight Divine Generals of the Human Ancestor Hall, Shen Lou. I already know."

"I'm ashamed." Shen Lou cupped his hands humbly, but his heart was even calmer. He continued to ask, "May I know who Fellow Daoist Hongwu followed here? Are you from the Cui Clan?"

This conversation confused the surrounding people. Why did it look like Shen Lou was not familiar with Hongwu? Then why were they sitting together?

Because of this so-called "Cui Clan"?
