In the next month in the mini-world, Sol was training his sun ice ability, he wanted to be a minor demigod before his trip to the underworld.

From what he heard, he would only need one of his abilities to reach a minor demigod rather than all his ability.

If he needs all his ability to reach that level before he becomes a minor demigod then it would take way too long, he would need at least three times the time of what normal people need.

But he suspects he would need was longer because the healing dome was too mysterious and profound for him to understand in a short time.

On the other hand, Sun ice was the easiest ability to master, not only the mini-world made entirely of ice, his future pantheon members are going to be ice element nymph.

Factoring that, Sol decides to practice the sun ice first, it was not easing for him as the sun ice behaves the exact opposite of what science describes.
