Most people don't choose reincarnation. Reincarnation finds their way to them. Perhaps they did something great in their life. Or maybe truck-sama wasn't looking where it was going. But without fail, those who reincarnate are destined for something great. A new life where everything changes for the better. But... Reincarnation isn't always the greatest thing. Sometimes you just draw the short end of the stick. Di Tou just happens to have drawn the shortest stick. Pulled out of his life randomly. Taken by a crazy old eccentric man not as a disciple, but as a body double?! And a janitor body double no less?! Grasping a system to find... It's a JANITOR SYSTEM!? Truly, how unlucky can one get?
In terms of personal preference, Di Tou much preferred it if the afternoon situation was more correct and approached the desired aura or demeanour of a janitor. That was because although it had felt like a fever dream, in terms of behavior, it much better matched Di Tou's own personality. As much as cultivation had probably inevitably changed Di Tou, at heart he was still Di Tou, a normal, mundane guy. All these things about spells and Qi, they might as well be new apps on his phone to try out!
