When the apocalypse came, Gu Yan died repeatedly in the zombie wave, and returned to the day of the disaster again and again. As a former bankrupt rich man, he used his cyclic memory to hoard supplies and predict crises, but he could never escape the inevitable death on the seventh day. Until he discovered that the only key to breaking the cycle was to save the self-made rival he despised the most in his life - Lin Che. He was forced to show kindness to, protect, and even risk his life to save Lin Che in every cycle, and gradually became addicted to the strange sense of security brought by the other party. Until a certain cycle, he arrived at Lin Che's hiding place in advance, and heard the other party calmly reporting to the radio: "Monitoring the target for the 89th cycle, the emotional dependence value has reached the standard, and the 'Ark' awakening plan can begin." It turned out that this survival game that he thought he was leading was, from beginning to end, a petri dish carefully created by Lin Che for him.
