Reborn as a Soul Banner, I Devour My Master

My head rolled, limbs twisted, consumed by a demonic ritual. I died a humiliating death, a sacrifice to a ruthless cultivator's twisted ambition. But death was just the beginning. I awoke inside the very artifact he crafted—the Soul Respecting Banner—its sentient main soul. My new reality: I am the weapon, and a terrifying system now guides my path. With every absorbed soul, every drop of evil energy, I grow stronger. The banner upgrades, unlocking powers, and the ultimate truth: I can backlash my master. That demon thought he controlled me. He thought wrong. Now, his screaming soul empowers my ascent. The world will soon learn: when you wield a Demonic Soul Banner, you are the one truly being wielded.
