[Introduction]
The protagonist, a teacher, discovers a time capsule from the past at the school where his son studies. Inside the capsule are some picture files with predictions about the future world written on them. Some of these predictions have already come true, while others may still happen. The most terrifying prediction is that the Earth will soon be destroyed, forcing the protagonist to take action within limited time to prevent its fulfillment.
In 1958, during a primary school celebration, a group of students worked together on drawings which were then placed in a "time capsule" for storage. All the students took it seriously except for one mysterious and strange girl who didn't draw on her paper but instead casually wrote down some numbers.
Fifty years later, out of curiosity, a group of students opened the capsule to check its seal and peek inside. The mysterious girl's paper from 50 years ago, along with those peculiar numbers, eventually ended up in the hands of a boy named Caleb Kestler, who handed it over to his father, Professor John Kestler. The meticulous professor discovered the secrets hidden behind these seemingly ordinary numbers - these numbers weren't randomly written by the girl; each number was closely linked to major disasters that occurred over the past 50 years. These numbers functioned like precise coordinates, accurately marking the times of the disasters and the dates when people died. Professor Kestler finally understood that these unusual numbers were indeed prophecies. After further studying these numbers, John discovered another prophecy about to come true - the Earth would be destroyed. In great alarm, John tried to get the authorities' attention to resolve the impending disaster early, but they showed no interest in these numerical games. Justice-driven John went through great lengths to find the daughter and granddaughter of the mysterious girl from 50 years ago, inviting them to join his cause to stop this disaster. Although reluctant at first, the two women eventually got involved. Naturally, Professor John became the leader of this team, initiating the battle to defend the Earth.
