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?
After working at the training center as a sparring partner for five years, naturally, there were people who noticed Old Gao and appreciated his work. Although his cultivation was a little on the low side, he had started to gain a small reputation as the best trainer for Qi Condesing Stage cultivators! That was because no matter what technique you practiced, this strange old sparring partner seemed to always be able to choose the best technique to counter you, and help you squeeze out growth.
Alternatively, he could use a technique that while perhaps not exactly the same, was about eighty to ninety percent similar and make up for the deficiencies in his own technique through unique changes and his higher cultivation. This couldn't be helped, Old Gao had pretty much only learned Low Tier Earth Grade Techniques, whereas most students of the Academy, at the very least, picked up a Mid Tier Earth Grade technique as their starting technique.
