Demon beast eggs

Just as he was thinking he suddenly had an idea, and he couldn't help but turn his head to look at the entrance where the eggs of the demon beast could be seen, at this moment he wondered what would happen if he was to use those eggs to level up?

Would he be able to recover his energy points, second-life hp, and first-life hp back? Although he wasn't sure but he was willing to give it a try, after all, there was no harm in trying if it could work or not, since demon beast eggs didn't really have any use to him in the first place.

However, he didn't stand up immediately, not that he didn't want to stand up but his energy points were only ten, and at this point even to walk had become a big deal for him, so he had to wait a little longer to recover his stamina, and then force himself to stand up afterward.
