The Zen of Spring and Autumn

The protagonist, Zhang Yuqian, was born to face a tribulation during the era when the emperors of Xuanhuang fell. Heaven's Way granted him immortality, and he was born with a Sacrificial Dao Body, nurtured by heaven and earth themselves. Patriarch Jiang Chengzi of the Xiaoyao Duxian Sect took him in as a disciple and passed down to him the Spring and Autumn Zen Intent. After sixty years of trials and tribulations, he returned to the sect, which spent every last resource it had to forge him a Sacrificial Dao Immortal Body. With a sword in hand, he alone swept away demons through nine cycles of reincarnation.
