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?
Careful Memorization
All in all, the Academy's techniques were indeed a step above. Of course, it also came down to Di Tou's own choices. The few options he had picked were the most 'boring' of the options on the list. There were naturally techniques similar to the [Spirit Axe] that only focused on a single thing and pushed it to an extreme, allowing him to exert much more power in any given instant than any of the techniques that Di Tou had picked.
Similarly, it would also be easier to pick up and learn, as the formula would be done for him. In a way, what Di Tou had done was pick up a book about handy work in general, as opposed to a set kit for a doghouse, where all he had to do was assemble the doghouse. Although both required a process of learning, the learning curve was naturally different.
