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?
Returning
When Di Tou was about halfway through the second vial, he realized he had reached the end of the crystal growths in the underground river. Standing still and stretching, Di Tou looked forward to seeing that although the water continued forward, and there was still quite a large stretch of the cave, there were no more Soul Sounding Crystals growing on the walls, the floors, or the ceiling.
He had finally managed to finish this stretch! Of course, when he said that, what he meant was he finally managed to collect all of the Soul Sounding Crystals that grew off the ground that weren't close to the river bank, on the wall, or on the ceiling.
There were still many crystals in those spots, not to mention on the other side of the river and back where Wu Kong and Jian Xiao Yu were still working.
