บท 1230: Debut of the Immortal Cultivators!

Li Yao and the Fire Ant King immediately understood what he was getting at.

Ordinary planets did not have an atmosphere or water resources because they were either too close to or too far away from a star.

If they were too close, it was barely possible for them to generate a force field that was strong enough. Most of the spiritual energy around the planet would be attracted by the star.

If they were too far away, they would be frigid hells due to the lack of radiation from the star. The spiritual energy would be equally inactive.

On such planets that were short of sunlight, water, air, and spiritual energy, even if the reserves of metal minerals were impressive, it would be a tedious project to excavate them from underground and refine them into high-purity materials that were good for magical equipment. A lot of corresponding factories and personnel were required. It was indeed impossible to be achieved in a year and a half.
