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?

Having calmed his heart slightly, Li Chang Hu examined the rock for a little while longer, and after a while managed to gain some insights of his own. At the same time, he was glad he had withheld the attack earlier, as although the rock seemed corporal, in reality it's defensive ability at the moment was rather low, as it wasn't being actively powered by Di Tou right now, but was instead a manifestation, or a sigh of Resonance.
Of course, this wasn't fully-fledged Resonance like that from an expert in the Resonance Stage, but instead a side effect of Di Tou's understanding of the technique reflecting itself in reality due to the technique being at the Resonance Stage. Overall, it looked impressive and was indicative of his gains, but in reality it was like a mirage or a bubble, with a little push it would pop.
