Just After Arriving, the World Will Be Upgraded?

Baiban's life is just like his name, ordinary and innocent. He doesn't believe in luck, so he never touches things based on chance. He doesn't believe in how special he is, so he enjoys the indifference of living on earth. But now, who told him what kind of ghost world he was traveling through? "Brother, do you want to change your job? Shadow Realm Envoy, the kind of giant bull." "What kind of cow is a giant bull?" "..." This novel and its characters are purely fictitious.
