In 2015 AD, a meteorite rain occurred across a large area of the world. The meteorite rain triggered major earthquakes and tsunamis, causing countless casualties and catastrophizing mankind. However, when the surviving people woke up from the darkness, they found that due to crustal movement, one-third of the earth's continents had sunk to the bottom of the sea forever. Along with this third of the continent, there are 2 billion lives left. It took a full 13 years for people to initially emerge from the gloom and resume their pre-disaster life. Just when people thought they had survived, a bigger crisis emerged - the energy crisis. The land area has been reduced a lot, and the reconstruction of human society has consumed a lot of energy, first coal mines, oil, natural gas, then iron ore, aluminum ore, and in the end even food is precious... Resource depletion is imminent. At this time, for the sake of their own interests and development, countries with relatively abundant resources became the prey of other powerful countries - war broke out.
