After Cheng Jinfa joined the sect, his master assigned him to train in the cave behind the sect, practicing the basic sword art “Chicken-Slaying Sword Art” and the fasting cultivation method “Earth-Eating Heart Method.” He trained so single-mindedly in the cave that he neglected food and sleep. A few days later, a flash flood struck and the cave entrance collapsed, trapping him inside. But even in this desperate situation, the protagonist refused to give up.
Every day, his only activities were practicing the “Chicken-Slaying Sword Art” and the “Earth-Eating Heart Method.” With no resources from the outside world, he could only rely on the cave's meager spiritual energy and his own unyielding will to keep cultivating. As time passed, both arts continued to break through their limits, rising from the first layer all the way to the ten-thousandth.
After a thousand years of lonely cultivation, the protagonist's strength had undergone a world-shaking transformation. The “Chicken-Slaying Sword Art” had reached the height of perfection, and every swing of his sword held the power to destroy heaven and earth. The “Earth-Eating Heart Method” had also given him an incredibly strong body and the ability to go without food, allowing him to eat dirt to sustain his cultivation. In the end, relying on these two arts, he cleaved through the mountain with his sword and ate his way through the earth, forcing a passage out of the cave and back into the light of day.
I think it's still okay.
