While restoring a Mayan altar, cultural relic restorer Chen Mo accidentally awakened the ability to perceive historical fragments, and was involved in a time-space rift town intertwined with the ancient Mayan civilization and the Red Cliff battlefield of the Three Kingdoms. Here, he met Su Huaijin, an archaeologist from modern times, and their fragmented memories began to overlap, revealing their astonishing identities as the leaders of experiments in previous lives. In the small town, the Mayan survivors, the travelers from the Three Kingdoms, and the indescribable Cthulhu Order are competing for control of the rift. Under the guidance of the "Space-Time Code System", Chen Mo must travel through the chaotic lines of history to repair the cracks. Every decision may rewrite history. And he and Su Huaijin gradually discovered that the price of repairing everything might be the complete annihilation of one of them. This is a lonely journey to find redemption and coexistence amidst the reverberations of history and the chaos of time and space.
