The new base of the humans from the blue planet was more than 1,000 kilometers long in length and width, and more than 100 kilometers tall. In the future, the size could still be adjusted to make it smaller and more hidden, or larger to accommodate more people.
With the current technology, they only needed to build a large number of tall buildings with hundreds of floors. Residences for the population of billions of people was not a big problem.
The secret realm in the otherworld was essentially linked to the abandoned world, but in reality, it was located in the space-travel distortion. Therefore, after the influence of the space-travel distortion was isolated on the outside, it was not affected by any natural disasters.
In fact, the natural factors that were commonly seen on a planet, such as day and night, wind, rain, and the content of air, still had to be artificially simulated by high-tech equipment.
