Unorthodox Cultivation: I Refine the World's Waste

The protagonist Zhou Xu is born with a crippled meridian system, rendering traditional cultivation methods like drawing in spiritual energy and guiding qi completely ineffective. Thus, he takes an unconventional path, cultivating using what the world deems as waste. He specializes in absorbing discarded turbid qi, scattered residual energy, and alchemical toxin remnants. Forbidden waste grounds within the sect and even the entire cultivation world—such as abandoned herb valleys, broken formation cores, trash-covered back mountains, and depleted spirit ore mines—are all paradises for him. This is because he can break through barriers using dregs, charge his spiritual roots with waste energy, and forcibly reverse marrow cleansing. He turns all the world's garbage into cultivation power and attains the supreme Dao through the dregs of all things. — Description from novelcodex.org
