My name is Xu Changsheng, a handyman sweeping the floor of the Buddhist Scripture Pavilion in the Dharma-ending era. The sect declined and the inheritance was cut off, until I discovered that I could "see" the incomplete "Guiyuan Creation Map" of everything. I can make up for the incomplete swordsmanship and its final killing move. A dead elixir, I can find the missing link to bring it back to life. An obsessive elder, I can locate the source of the conflict between his techniques. I fill people's vacancies and receive "reward" - their purest ray of mana, a piece of memory, or a trace of luck. I quietly completed all the incomplete skills of the sect, and then people discovered that this handyman sweeping the floor could do everything? Gradually, they began to call me... The source of all dharma, Dao Shi Tianzun.
