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 last Ascender before the Heavens collapsed?

Cui Heng was a little surprised when he heard this. He could not help but think of the description of how to break through to the Seventh Realm in the Purple Sun True Treasure Records.

According to the description in the book, one could only cultivate to the Peak of the Sixth Realm in the myriad worlds. If one wanted to break through to the Seventh Realm, they had to ascend to the Heavens.

The Purple Sun Heaven was once one of the Heavens.

Then was the collapsed Heaven mentioned here referring to the Purple Sun Heaven?

After all, the people of the Purple Sun Realm claimed that their realm was a fragment world of the Purple Sun Heaven after it shattered. They used this to show their orthodoxy and nobility.

If this great divine being who had walked out of Daozhou Star was really the last Ascender, then he might really have some extraordinary secrets.
