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

Hundred Sage City was a new city that had been established in the past 20 to 30 years. It was located not far from the Nine Deaths Heavenly Sect.

However, although this city had a short history, it developed extremely quickly. In just 20 to 30 years, it had already become the most prosperous and vast city on Chongyang Star.

The reason was very simple. There were more than a hundred Limitless Golden Immortals here who had become Sages. At the same time, it was also where the Nine Deaths Heavenly Sect sold the Myriad Techniques Return to One Pill.

More than 20 years ago, many people from the other myriad worlds and starry skies had come here to buy the Myriad Techniques Return to One Pill from the Nine Deaths Heavenly Sect. In order to make it easier to receive the guests, the Sect Master of the Nine Deaths Heavenly Sect, Pei Qingshu, ordered the construction of this large city.

After the city was built, countless martial artists and merchants flocked over.
