I Am Building a Blue Star in the Interstellar

In 3205 AD on Blue Star, human beings entered the age of population explosion. After a natural disaster 500 years ago, the human population was greatly reduced. The movement of the earth's crust merged all the plates to form one large plate. Blue Star became half ocean and half land. The surviving humans lived together regardless of race or national boundaries. After 200 years of running-in, they all became citizens of the Republic. In 300 AD In 2000, mankind entered the high-tech era. It took 200 years for the population to reach 50 billion. It took 4 years for Blue Star to exhaust all its resources. At this time, Blue Star mutated. When humans escaped from Blue Star, only 100 million people were left. They wandered in the universe for 100 years before they found a planet suitable for survival again. They called it the Central Star. From then on, Blue Star became a forgotten planet. Later, Yang Yu was lucky enough to return to Blue Star, only to discover that Blue Star's history was all false.
