Kairos did think of the fact that spending so many points would make him extremely hungry, but he figured that he could deal with that later and fight with the creature right now. Considering that he had already been hungry because of how little he had eaten before, the effects were magnified several times over.
Unfortunately, he had vastly underestimated the effects of using so many points and overestimated his own capability to withstand it.
In fact, it seemed that his body was on the verge of breaking down because of excessive energy consumption, and he didn't even have his backpack with all his food in it. Kairos began to regret his decision, but also did not think that his current stats were even enough.
He was hoping to somehow be able to bear it, but that turned out to be too much for him.
Wow, this guy is good at gardening! Why don't they bring him back to the city?
