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?
The process of figuring out a technique for the Nascent Soul version of Spirit Song Sword wasn't particularly difficult, just a little tedious. And, of course, the majority of the work fell onto An Yang's shoulders, and Di Tou could only dumbly act as a tester and do whatever An Yang requested from him. In any case, to begin with, Spirit Song Sword, both the sword itself and the technique had been designed with the intention of being a Nascent Soul Stage technique, too, and what Di Tou had learned before could be considered the dumbed-down adaptation.
