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

"Of course, of course." Ren Yuankui nodded repeatedly, then lowered his voice and asked, "What did Overseer Shen say? Has it been decided?"

"Heh, I was waiting for you to ask." Wei Xiong took a sip of wine and said with a smile, "30% of 10 years' tax for Fengzhou's 12 counties. Lu County is rich and prosperous, so we want an additional 20% from there. How about that?"

"This…" Ren Yuankui's eyebrows twitched when he heard this. He smiled bitterly and said," You know that in order to gain the support of the Ye and Jiang families, I've already given 40% of Fengzhou's taxes to them. If I give 30% more… "

"Hehe, Governor Ren, don't hide it from me." Wei Xiong sneered and said, "I don't believe that you won't increase the taxes after you take office. What we're setting now is only the current tax rate!

"Even if you give out 100%, as long as you become the Governor of Fengzhou and double the tax rate of those bumpkins, won't you earn it all back?"
