白天送快递，晚上埋人 

Delivering express during the day and burying people at night

Sun Haoran thought he had traveled to the world of "Under One Person". He was a mediocre person who originally just wanted to deliver packages quietly and wait for death. Until one day he was scratched by a little dragon who suddenly jumped out! I just want to deliver a package quietly, but you actually told me to slay a dragon?
