The Invincible Tortoise-Shell Taoist

Ma Ning, an overworked college student, dies suddenly after staying up all night and transmigrates to Fengdu County in a parallel world. He discovers that he has the strength of an Immortal at the pinnacle, but all he wants is to lie flat. He takes over a funeral shop that's gone out of business, hoping to start a laid-back life of "making enough to get by and staying out of trouble," but his first job forces him to reveal his true strength.
