Zhou Mancang, a waste handyman at the bottom of Qinglan Sect, can hear the residual obsession of waste, and after completing his obsession, he can extract the "remaining power of all things" that his master has not exhausted; he secretly became stronger by relying on other people's unwanted garbage, and when everyone regarded him as a lucky little person, he gradually picked him up and became invincible in the world. Zhou Mancang finally discovered that the current practice system is a "successful version" selected by the ancient strongmen, and countless paths that are more suitable for ordinary people have been abandoned as failures. He will recycle the incomplete rules, piece together the deleted history, and establish a new practice system that does not determine the upper limit based on bloodline and origin.
