Foolish Old Man No. 1

In 2085, when human society was highly developed, an ore refining accident on the Antarctic continent caused the Antarctic glaciers to completely melt. Tsunamis and earthquakes occurred one after another. Humanity suffered the heaviest losses since World War II. Shortly after the earthquake, strange things happened. Small objects on the ground began to float in the air. Human scientists discovered that it turned out that the gravity of the earth beneath our feet had changed, and the gravity was getting weaker and weaker. The detection results of the world's only super Earth exploration satellite showed that an oval collapse crater with a diameter of 10 kilometers long appeared on the surface of the inner core, and the crater The surrounding material is still collapsing and decomposing. According to computer simulation experiments, according to the current trend of weakening gravity, in one month, objects with a mass of less than 0.5 Kilograms will completely lose gravity. After half a year, objects with a mass of less than 100 tons will also lose gravity. After a year, the gravity of the earth will completely disappear, and mankind is about to face a disaster! In order to save mankind and the earth, a rescue team formed by China, the United States, Russia, Japan, and India is preparing to take the Yugong 1 rescue submarine to go to the core of the earth, repair the damaged parts, and restore gravity. A race against time, Operation Yugong, has officially begun...
