You Pick Fights with Demon Kings and Goddesses? Why Mess with Him?

Transmigrated to another world, he became an invincible Demon King? And with an immortal body that can only be killed by a hero? All Lu Xun wants is to return to Blue Star, so he starts investing in heroes like crazy. The hero's level is too low? Send over an experience package: cripple a monster and deliver it to the hero! The hero has no gear, and isn't strong enough to beat the monsters? All demons, heed my command! Launch a full-scale assault on the dungeon and bring me the hero's divine sword! A goddess dares to stand in our way? I'll knock her teeth out! Anyone who lays a finger on the hero dies! Looking at the hero, shining with golden light, Lu Xun sheds a tear of satisfaction: “See that? I raised this hero from nothing, feeding him every step of the way.” What? The princess wants to assassinate the hero? The goddess wants to assassinate him too? What is wrong with all of you!?
