The Legendary Janitor
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?
Soul Techniques
Of course, Di Tou didn't know the elder's thoughts, and even if he did, although he might call the elder a madman in his heart, he would also hold some respect for the convictions of the Selfless Pavilion. It was a bit… departed from what Di Tou would call being a human, but then again, that was their whole point, so in a way, it checked out.
After thinking for a long time, Di Tou's mind finally cleared up, and he realized, to his dismay, that the majority of the information and techniques that he had flipped through were indeed useless for him. They were either incomplete theories, had aspects that weren't compatible with the current times, or had effects that although wondrous, didn't suit Di Tou's desires. After all, what most people wanted from their soul was for it to be more robust and lively.
