Normally, all domains where living beings exist are domains that can grow. These domains stretch across the stellar space, gathering and absorbing the omnipresent stellar space energy, expanding themselves, and gradually enhancing the foundation and level of their world.
However, this process is quite slow. Each time the world's level is raised, it can take hundreds of thousands to millions of years, and the higher the world's level, the slower the progression.
Yet the vastness of stellar space contains many wonders, and there are always a few special domains in this world that can devour the depth of other domains to enhance themselves. These domains are called growth-type domains.
They possess abilities that ordinary domains do not have.
In the currently expansive stellar space, the most powerful domains, nine out of ten, are such growth-type domains.
