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?
Watching Master Yong leave, Di Tou was speechless for a while. To be honest, after actually working through his plan, he found there were indeed quite a few issues and complications. The main one being that ultimately, formations weren't miracle makers, and functioned like machines. They used energy to create a cause and effect, which also meant that they couldn't make something from nothing, and couldn't make something into nothing either.
It wasn't like his Void Qi, where a simple spray would return things to an empty state.
