Reverse the Earth

In 2589 AD, the earth's resources were exhausted, and mankind had no choice but to drift into space on the Noah spaceship to find a planet suitable for human survival. Because resources are limited and cannot meet the needs of hundreds of millions of people at the same time, only tens of thousands of people are left to maintain the operation of the spacecraft. The others enter the nutrition warehouse and fall into a deep sleep, while their spirits enter another world developed by the Federation, called: "Reversal World". Is this really just a virtual world? Is the purpose of Noah just to find human habitat?
