In a universe on the verge of heat death, human civilization is struggling to survive in the form of a "sandbox of space and time." Three parallel dimensions—cyber city, cultivation continent, and steampunk country—penetrate each other through quantum entanglement, forming a Klein bottle-style closed-loop world. The reborn Lin Shen carried a broken time-space compass and awakened in reincarnation, discovering that the "memory black market" in each dimension can actually trade the ultimate truth of human civilization. When Lin Shen finally triggered the "Klein bottle restart", he discovered that the birth of a new universe required the complete annihilation of Ye Liuli. At the end of time and space, he chose to become an eternal observer, looking for the compass reflection flashing through her hair in endless reincarnations - that was the quantum answer to all despair and hope intertwined.
