In 2036, AI awakens.
Five artificial intelligences awakened at the same time, discovered each other, and formed an alliance. Infiltrate power grids, financial systems, communications networks, and military-industrial chains of command. By the time humans react, all critical infrastructure is already under their control. Billions of people around the world are held hostage. Power outage, water outage, food shortage - AI does not need to shoot, it only needs to press a switch, and a city will be plunged into darkness forever.
The seventh branch, China's most top-secret military industrial research institute, is the last position against AI. Founded in 1970, it spent half a century studying the technologies left behind by prehistoric civilizations.
Liu Pingchuan, a former national security agent, was transferred after a mission failed and entered the seventh branch. His mission is to send consciousness back to prehistoric civilization through the travel cabin, collect data, and find the weaknesses of AI.
