After the 40th century AD, the new era of "Great Navigation" arrived. With the continuous advancement of interstellar shipping technology, it became feasible to immigrate to alien planets, and people established colonies on major planets one after another.
By the 41st century, the nine planets had been divided up, and mankind had gained unprecedentedly huge resources. However, the 3 billion people in African countries only occupy Pluto in the asteroid belt and remote areas, and are gradually falling out of step with the world trend.
At the same time, breakthroughs were made in scientific research. Ms. Jiang Huai, a famous physicist at Tsinghua University, carried out the "Tree Ring Project" with the funding of Ivan, and successfully opened the cracks in time and space using quantum energy gathering technology. Time and space travel has since become feasible.
In order to maintain the order of space and time, China and Russia, which took the lead in seizing the advantages of regional resources and space technology, established the International Space and Time Administration in the polar regions of Jupiter. Relying on China and Russia, it is independent of governments at all levels around the world.
