When he was ten years old, Lin Su won a business lottery. From then on, he could receive free iced black tea for life.
Later, the end of the world came and human civilization was destroyed. The city became a ruin overgrown with glowing fungi. Lin Su wandered here alone for more than a year and never saw another living person.
However, the old-era delivery system is still in operation. On the morning of the first of every month, no matter how deep underground Lin Su hides, a brand new box of iced black tea will always appear next to him on time. This unexplainable and precise delivery made him extremely puzzled.
In order to find out the truth, Lin Su used discarded parts to piece together a detector. He decided to track the invisible delivery drone in reverse.
In that huge unmanned factory buried deep underground, is it the rigid artificial intelligence that is blindly executing the Old Testament? Or does it hide the last hope of human civilization? A long journey to explore the truth of the doomsday begins.
