This completely confuses him, his stat window then fully opens, and a divine voice announces that this window displays all of his current abilities, along with numerical values to make them easier to understand.
The divine voice continues, explaining that even though dragon eggs are at the very bottom of the food chain, they have the potential to grow into fearsome dragons over time.
This confirms for him that sleeping fully refills his health bar, which at least gives him one small sense of relief in this strange and dangerous new world.
Hearing this leaves him feeling confused, he starts wondering if the divine voice only said that because he chose the little dragon simply because it was the safer option rather than taking a risk.
From that, he starts to suspect that the little dragon might not be able to evolve very far, or possibly might not evolve at all after a certain point.
The system accepts his decision and grants his wish, and in the next moment, his body begins to change as he transforms into a yellow baby dragon exactly as requested.
However, despite evolving, his HP and MP don't refill afterward, which means he's still exhausted and will need some proper rest before pushing himself any further.
He explores for a while until he spots a gray wolf nearby, and even though it's bigger than him, he still manages to use his baby breath and dragon punch to take it down.
After everything he endured and all the effort he put into evolving and surviving, it feels like it's all about to end in a meaningless and pointless death.
