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?
Summoning a Scroll (Why does this seem familiar...)
But this was only because the gap between the two of them was much too large. If Old Gao was of a similar cultivation level and was able to be immune to the cultivation methods and the Qi that most people used, wouldn't it be a situation of having to fight with a hand behind your back? In an even fight, Old Gao would surely come out on top.
And this wasn't even considering the fact that Old Gao had mentioned something about gaining resistance to similar effects. Without testing, it was hard to say how valuable this was, but if Old Gao learned a hundred Earth-tier fire-based manuals, would he become immune to fire-type effects altogether? Immune was a terrifying concept.
