IMMORTALITY

Fang Han, a humble family slave, always held the belief that "I would rather be a beggar than a slave", traversing the world only by himself. With an unyielding stubbornness, he cracked the mystery of supernatural powers and forged his body into an immortal body. He worked hard to step into the fairyland, and eventually became the peak king. (Source: bilibili) — Description from AniList community (anilist.co).
