After My Ascension Failed, I Became a Sect Cleaner

Three thousand years ago, I was the number one swordsman in the world of cultivation. When I ascended, I was struck into the toilet by a purple thunder. Three thousand years later, I woke up in a garbage dump and found that I had lost all my cultivation. In the sect's assessment office, the elder looked at my spirit-testing stone: "Miscellaneous spirit roots? Go clean the toilets in Jingchen Hall!" I silently took out the first-generation ancestor's token as a bath towel, turned around and walked towards the smelliest post in the world of cultivation. On the first day of cleaning up the forbidden area, I muttered to the seal: "How did the garbage I threw away back then become a treasure of the clan?" The next day when I was cleaning the alchemy room, the elder roared: "Who touched my Nine-turn Resurrection Pill?" I held up the half-eaten jelly beans: "What do you mean? The taste is okay but a bit hard." Until one day, the mountain guarding formation was breached by the Demon Lord. I raised my broom and said, "Disciple, after three thousand years, you are still so unimproved."
