In 2045 AD, Yongsheng Biotechnology Company made a breakthrough in anti-aging research - a compound called "Telomerase Activation Factor-9 (TAF-9)" was able to achieve telomere reversal in animal experiments, extending the life span of experimental mice by 230%.
This achievement shocked the global scientific community and capital markets. The market value of Yongsheng Pharmaceutical has soared to US$800 billion, and the global anti-aging drug market is following suit.
However, the lead researcher Fang Henian concealed a fatal problem: while TAF-9 prolongs the life of cells, it also destroys the apoptosis mechanism. ** To put it simply - cells become "immortal". In in vitro experiments, some cells began to divide and proliferate uncontrollably and completely ignored normal apoptosis signals, directly causing a large outbreak of the Z virus.
The Z virus has a strong ability to mutate. As time goes by, "evolved species" will continue to emerge among the ordinary zombies. The "devouring" behavior between zombies - high-level zombies devouring similar crystal nuclei - will accelerate evolution.
After being infected by the Z virus, 99.99% Of humans will have their brains destroyed and become zombies. However, a very small number of individuals (about one in 10,000) have special "suppressor factors" in their genomes - a "junk gene" that has never been activated in the history of evolution.
By chance, the protagonist Jiang Chen led a group of immune people to start a doomsday survival, fight against zombies, and build a refuge home.
A very good one
