The Apocalypse Is Coming: I Use AI to Build an Underground City

In 2032, Lin Quan acquired two things in just two days: a charred bracelet from beyond the stars, and a windfall large enough to build an underground city.

The smart AI extracted a terrifying warning from the bracelet: a strain of alien infection that had once destroyed an extraterrestrial civilization was approaching Earth alongside an asteroid fortress. It would arrive in as little as seven months.

Lin Quan had no way to prove any of it, and no one believed his warning. Nor did he intend to play the savior.

While the cities remained brightly lit and people went to work, bought homes, and planned their vacations, Lin Quan used a geothermal power project as cover to upgrade the AI, dig into the heart of a mountain, and gather robots, chips, medical equipment, and a century's worth of supplies. He secretly transformed an abandoned sanatorium into a self-sufficient underground city.

Seven months later, fire streaked across the night sky, and infection and chaos swept the world.

While people outside struggled for food and safety, Lin Quan sat down to dinner with his family in the underground restaurant. The greenhouse had just yielded its first basket of strawberries, and an unmanned vehicle was returning laden with supplies from the silent city.

He had only one thing to do:

Protect his home, live in peace, and wait for the AI and humanity to outlast the apocalypse.
