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?
Behind him, Wu Kong's mind was in a mess. At first, he thought that Di Tou was a little bit silly and that his logic was plain, and he failed to see the crux of the issue. It was simply the mindset of a demon sympathizer who thought it was 'justice' for the demonic people to take their revenge and kill whoever was in their way. Someone who didn't understand that for each act of 'retribution and justice' that the demonic people performed, thousands, if not millions, of lives of the innocent were used to pave the way.
Although justice had many problems, and many people were hypocritical, vile, and arrogant, overall, the system was called justice because it brought prosperity and livelihood to the largest number of people. But in the end, as he heard Di Tou continue to speak, he couldn't help but feel shocked in his heart and be drawn in by the naive logic.
