Yunji is the executioner who restarts the memory of the Night Watcher for the seventh time. His left hand holds the last remnants of the deceased, and his right hand is stained with evidence of crimes that cannot be cleared away. Lu Yao is his only observer and the only anchor point that cannot be tampered with when his memory collapses. When every corpse repeats the same death pattern, every last word points to the same truth - they are not investigating death, but fighting against a nightmare that keeps replaying. Yunji's consciousness was being devoured by the dead, but Lu Yao stuffed a rusty knife into his palm before restarting for the seventh time: "This time, don't save them, kill the person in the cycle."
