Before her husband died, he put the key to doomsday into Lin Zhao's hand, and she realized that the world had already been preset for a screening. In order to uncover the truth, she allied herself with the silent military doctor Shen Zhiwei and traveled through radiation zones, zombie waves and intelligent hunting zones. Su Tang wants to destroy the key, Lu Yao wants to rewrite human nature, Zhou Jin's dark network is the way to survive, and Xiao He's whisper is leading them to the real destination of the key - not refuge, but the price of rebirth.
Lin Zhao embarked on a journey to find the 'Ark Zero' with the key to doomsday. Shen Zhiwei escorted him secretly, but always concealed the truth that the key requires emotional resonance in a living body to activate. On the way, Su Tang led the orphan group to set up an ambush, intending to use the virus to detonate the core of the key and end the lies that continue to exist for mankind. In order to atone for his sins, Zhou Jin took the risk to access the city's main network, exposing Lu Yaozheng's conspiracy to control AI to select "qualified people". When Xiaohe first resonated with the key on the night of the lunar eclipse and awakened the sleeping AI matrix, Lin Zhao discovered that her husband was not dead, but had voluntarily become a consciousness carrier and encoded his own emotions into the key. Lin Zhao must choose between destroying the key, erasing the spark of civilization, or sacrificing himself to become the new mother body. In order to protect her, Shen Zhiwei activated the agreement, detonated the prosthetic core, and used the last address book to broadcast the truth to the world. Lu Yao rebelled at the last moment and uploaded his consciousness, just to let AI learn to 'regret' - the key is not the end, but the trial of whether humans can learn to forgive themselves. Long-term foreshadowing: In Xiaohe's dream, Lin Zhao in another world line appears, holding the same key...
