Turned into a Corpse Retriever? I Rule the Underwater World!

The moment He Chi opened his eyes, he saw something he had never encountered in his first twenty-some years: a corpse! This world completely shattered the worldview of a young man from the new century! Corpse fiends! Dragon Kings! Little ghosts! Calamities... He transmigrated into a fused world and activated the Check-In System. A strange, dangerous female corpse in the river? He casually hauled it off and put it in a grave! His second uncle was being tormented by a little ghost? A soul-path emissary came to help! Why was he always fighting opponents above his level? And yet he won every time! He led the He family from ordinary corpse retrievers to an immortal clan that dominated the world!
