Eternal Tumor: My Cancer Cells Made Me Immortal and Invincible

When a dying man with terminal cancer gets thrown into a mystical realm by a time anomaly, he discovers something impossible—his cancer cells have mutated into the key to eternal life. Unable to cultivate like others yet standing at the apex of power from day one, Chen Yun becomes this world's ultimate paradox: a living tumor that refuses to die. But immortality without strength is just a longer death sentence. Now, this unkillable anomaly must forge his own path to true invincibility across countless realms.
