Chen Yan is the only "awakened" ghost in the three thousand parallel universes. Doctor, killer, tyrant, hero... Memories of billions of identities exploded in his mind at the same time. When he holds the scalpel, the experience of 100,000 accurate dissections flows through his fingertips; when he raises the gun, 8,000 assassination techniques automatically calibrate the trajectory. Until the "hes" of all the universes begin to hunt each other - because the ancient prophecy is being fulfilled: when all things are unified, the universe will be reborn or annihilated.
