Wo Xiashan Zhihou Wudile

Liu Mo went through ten years of strenuous cultivation until he formed an infant immortal body, and only then was he ready to leave the mountain and head out into the mortal world. But... "I only just formed an immortal body at 18, but there are people who have already ascended to heaven by age 8. I must not have much talent at cultivation!"

"This world seems awfully scary, there are powerful folks everywhere..."
