Start Cultivating Immortality from the Valley

Chu Tianshu, who grew up in a single-parent family, was deeply affected by the unexpected death of his father. So, he decided to come to an isolated valley and live in seclusion. But when he first started to live in seclusion, he inexplicably traveled to a world where everyone was cultivating immortals... (PS: In the early stage, he lived in seclusion in the valley, in the middle stage, his spiritual energy revived and he cultivated immortality, and in the later stage, he came to the world to survive.)
