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

A dark golden giant-like Yellow-scarved Strongman appeared out of thin air.

After he appeared, he bowed to Cui Heng and said respectfully, "Greetings, Master Immortal!"

Cui Heng pointed at the young woman opposite him and said in a low voice, "Kill her."

He did not care about the goal of Heaven's Will. He only knew that Heaven's Will had deliberately lured him here and even used the Ancient King Supreme Treasures to set up a huge array to imprison him here.

After the Yellow-scarved Strongman received Cui Heng's order, he immediately nodded and said, "Yes, Master Immortal!"

Then, he looked at the young woman and raised his hand to punch forward, accurately striking her.

This punch was not fancy at all. It did not even contain the power of the Great Dao laws. The young woman who was punched stood on the spot and was not injured at all. It was as if it was just an ordinary punch, and it was an extremely light punch.
