I Rely on My Sick Energy to Farm and Become a Saint

Others rely on spiritual energy to cultivate immortality, but I cultivate "Plague Canon" to absorb the energy of illness! Traveling through the world of cultivation, Mo Xuan became the "God of Plague" that everyone avoided, but unexpectedly obtained the "God of Plague Medical Code"—— An obsessed swordsman? Excellent spiritual fertilizer! A demon with a backlash? Excellent nourishment! Opening a medicine garden, refining evil elixirs, and building a "disease qi bank" to store disease qi in exchange for yang and longevity. The plague evil qi that others fear like a tiger is all the nutrients for his cultivation! Until one day, the Immortal Alliance crusades against him for raising the plague, and the Demon Cult covets his furnace of disease energy. Mo Xuan sneers and lifts his robe, revealing cancerous streaks all over his body—— "The Heavenly Dao Spiritual Vein that you kneel down to worship..." "It's already fucking cancer!"
