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 battle at Dacheng Pass was a heavy blow to the entire Liang Kingdom.

Before this, the Liang Kingdom had only been repelled when they attacked Wu Kingdom's Qinshui Pass. However, they were only repelled that time and did not suffer much.

Moreover, the Wu Kingdom was also an overlord-level country and was powerful.

From this point of view, the Liang Kingdom and the Wu Kingdom were actually on the same level. If they were only repelled once, it would not cause much damage to the Liang Kingdom.

However, the battle at Dacheng Pass was different.

Chen Kingdom was just a small country that was struggling at death's door because of its special geographical location. It was extremely weak.

It could not be compared to an overlord-level country at all.

No citizen of the Liang Kingdom would think that their country's army would suffer a setback at Dacheng Pass.
