Story of: My sister became a devil in another world and gave me a cute girl

Lu Tu traveled to a parallel world where games and reality merged, and everyone worked full-time. Everyone despises changing jobs and is called a cursed profession: Summoner. But Lu Tu didn’t panic at all, because his elder sister also traveled through time and became a demon king in a different world. At the beginning, a super full-time mage is sent, with invincible damage output and defense, and a cute white-haired girl. Sister: Brother, are you still missing someone? There is a shortage of everything here, except for professionals. Unknowingly, with the dual assistance of the system and his sister, Lu Tu found that he was invincible. Lu Tu: Sister, what is it like to be a demon king in a different world? I want to try it too.
