Ward No. 7

In 2024, an old internal medicine building built in 1958 at Renai Hospital Affiliated to West China University of Medical Sciences will be demolished. During the last comprehensive inspection before demolition, workers discovered a secret ward that had never been recorded on the architectural drawings - "Ward No. 7" On the second underground floor that had been sealed for a long time. In 1976, an extremely secret research codenamed "Immortal Embryos" was conducted here. An ancient retrovirus extracted from ancient permafrost buried 3,000 meters underground has been activated and can rewrite telomerase expression in human cells - theoretically enabling cell immortality. However, the virus quickly mutated uncontrollably, causing the infected person to experience a strange "biological clock inversion" phenomenon: the body gradually reversed growth, from an old man to a baby, and finally reversed to the state of a fertilized egg and "disappeared".
