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?
Win-Win! Or something like that...
The soul was a mysterious thing, and the majority of powers and sects across the world knew very little about it, only having a scarce few techniques that directly related to the soul that they didn't understand, but practiced as inheritance from generation from generation.
To further emphasise the point of how special the soul was, it had to be recalled that although the Nascent Soul stage was a high stage of cultivation that few would reach in their lives, it was also the one that cultivators stalled at. Most cultivators who ascended to a high stage would spend the majority of their lives in the Nascent Soul Stage, not daring to break through to the Resonanace Stage, as one would need confidence not only to pass Resonance but also into Void Returning. It was scary, and it was unstable. The life span of a Nascent Soul Stage expert was already very long, and advancing to the Resonance Stage didn't increase that lifespan at all.
