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 truth was Di Tou had the idea to set up this formation quite a while earlier, as this was a major issue Di Tou had been running into in general. In the Academy, it wasn't very polite to extend out one's Spiritual Sense wantonly, especially not to the extent of a domain. For instance, when coming across a cultivator of the opposite gender, extending out your Spiritual Sense was like widening your eyes and being able to observe minute details, like the quality of their robes, the designs, and the stitch being used. Extending out your domain was like being able to observe all of that, as well as the contents beneath the clothes, like the way their skin rubbed against the fabric, how many hairs they had on their head and elsewhere, and other such nitty-gritty details that were honestly none of anyone's business but their own.
