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?
Arriving before Li Chang Hu's home, Di Tou suddenly realised there was an issue. In regards to Li Chang Hu… he really didn't know how to prove his identity. After all, although Sister Jue had given him a pass, she also hadn't really gone out of the way to give him a way to prove his identity, and as such, he had had to face the difficult issue of 'proving' himself each time.
In Thousand Li Stroke, he still had a few secrets and methods he could mention to prove what had occurred, but with Li Chang Yin and Li Chang Hu, the stories he had to tell mainly had to do with what had happened in the Academy, and although there were plenty of shared stories, for the most part they were all things that had happened in public, either in a lecture, or in an open area. In theory, any student from the Academy in that era could tell the same stories if they so wished.
