Was there a novel in which the main character was a little fatty who was extremely lucky to have a Xianxia theme? Moreover, he was the sect master, and the weapons he used were the Mirror Slash, Thousand Slash, and Hundred Slash?

This novel was called Wild Eight Precepts. It was a Xianxia-Mythological Cultivation novel. It told the story of a little fatty. His identity was unknown, but he was very lucky. He became the Purifying Altar Envoy of the Buddhist Sect and the new generation of Demon Masters of the Demon Race. In the end, he became a sect master. In the novel, he also used a weapon called the Mirror Slash, which could kill thousands and hundreds. I hope you like my recommendation.
