A long time ago, when the earth was born, a planet - the earth - appeared in an unstable area around the earth, which indirectly led to the earth's future devastating disaster.
Around the first month of the year 4532 in the Chinese calendar, the earth's crust suddenly moved overnight. The movement was extremely fast and irregular. As a result, many small countries were destroyed overnight, and the global population was reduced by nearly half. The surviving people were panicked, fearing that it would be their turn next.
In order to deal with the crisis, scientists came up with many plans, eliminated all other plans, and finally decided on the only plan, which is called the "Human Train Migration Plan."
Purpose: Take a train under the stars to explore the lost secrets, which are taboos in the universe.
