Transgmigrating as a Succubus, Becoming a Livestreamer in Hell

"WTF, the streamer's lunch is roasted dragon meat!" "Why are there so many fallen angels circling the streamer?" "Hey, Streamer, can I take another look at that captured elf? Just one look and I'll tip you a billion~" … Having transmigrated into Hell, Roy has become a beautiful succubus. He has also obtained a live-streaming system. As long as he obtains enough reputation in his streaming room, he can have a draw at the lottery. Tips can be used to purchase the items in the system's store. With nothing to do, Roy live-streams his days as a devil. When he has nothing to do, he builds up the city defenses, expands the territory, tortures heroes, capture dragons, and abduct an angel or two from Heaven. And without realizing it, he becomes a great demon king that sends the world trembling.
