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?
New Techniques
To be honest, Di Tou didn't really understand how to use this attribute, and the majority of the cultivation world didn't either. Mental Strength was a rather vague sensation. The human mind has millions of thoughts, but the majority of people can only focus on one or two items at a time. Any more than that, and they'd be prone to forgetting details. This creates sensations like deja vu, or instinct, in which the subconscious mind picks up on details that your conscious mind doesn't and points out the fact that something is wrong or there is a discrepancy. Following this line of intuition, a talented detective or cultivator can pick up 'clues' and 'hints' out of midair, resolving difficult problems and causing others to feel like they're omniscient.
But the reality is that truth is simply in the details.
