Dou Er! Sex Change? Little Huo Niang! I Have Kuromi

As a player with dual cultivation of Narukami, Miku accidentally came to Douluo Continent and found that it happened to be a timeline a few years before the start of the second part. Just when he was worrying about how to deal with the final boss, Tang Shenwang, the system that was necessary for time travellers was officially launched. But unlike most senior time travellers, he has two systems! One is named Mi Xiaozi and the other is named Ku Luogou. The two systems kept arguing, so Miku ordered the two to merge into one. So a brand new system appeared, for Kuromi!
