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 exact method was relatively simple.

He could just use a spell to connect the planet to his portable space and put the entire planet inside.

The fourth was the most direct way.

It was to use a powerful attack to directly destroy this planet.

In other words, "Star Destruction"!

This method had extremely high requirements. Even Cui Heng, who was already at the Late-stage Nascent Soul realm, was not completely confident in succeeding.

After all, he had never used his full strength after breaking through to the Nascent Soul realm, so he did not know how powerful his strongest destructive power was.

However, no matter which method it was, it was not something that a Sixth Realm Immortal could do.

This meant that it must be experts at the Seventh Realm of the Immortal World.
