Manga Like Wo Zai Xiuxian Shijie Chao Jiu Wan Wu

Hua Qingyuan, dies suddenly due to overworking on a ‘996’ schedule. However, he finds himself transported to a fantasy world to become the top disciple of the Qingyun Sword Sect. Determined not to repeat the mistakes of his past life, he resolves to work no more than eight hours a day and not waste even a minute on extra cultivation. He becomes an anomaly in the sect, relaxing under a tree, enjoying his life after work, even as other disciples practiced day and night. Nevertheless, his unmatched talent in swordsmanship still makes him a formidable presence. So he keeps getting requests for help from his fellow disciples, his master, and even the sect leader himself. But no matter if it's a sneak attack from the demonic sect or a challenge from other young masters, Hua Qingyuan remained resolute: do not bother me outside working hours!!
