This Swordsman Is Invincible but a Little Neurotic

Xu Yiye was supposed to travel to the fantasy continent, but due to a system error, Xu Yiye was transported to the gap between the two worlds. In order to protect the host, the system directly imprisoned Xu Yiye in the crack for thousands of years, and he could only practice swordsmanship in the crack. Thousands of years have passed, enough for Xu Yiye to become a sword god, but he was also imprisoned and became a lunatic. This novel and its characters are purely fictitious.
