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?

Not wanting to cause any trouble and also knowing that there was no point arguing as he was already getting plenty of good treatment by being allowed to see and trade for what was here, Di Tou simply traded for a few simple techniques that were direct upgrades to what he had already learned, filling in for the deficiencies that had formed from his sudden increase in strength. After filing through the Spiritual Sense and Mental Force techniques, Di Tou then turned his eyes to techniques related to the aspects of Strength and Speed.
Looking at these two categories, although the number of techniques available couldn't be considered plentiful either, it was still a good chunk more than what he had seen when searching for Spiritual Sense and Mental Force related techniques, and there were some options available.
