If he maintains the survival state he had at Tuhill Village, he will be very useful.
He sleeps only two hours a day, and at night he relies on his night vision to go out hunting. He is very strong and moves nimbly.
But that is too exhausting.
If he follows a normal daily routine, he wouldn't be as strong, just an ordinary person, perhaps even worse than these primitives.
He feels he's facing a hurdle. He must find a way to get through this hurdle.
As for why he's being put in such a rough position, he doesn't know.
It seems this is a normal difficulty.
If he doesn't want to live as hard as a true primitive, he has to work even harder.
Challenges in a career are right. The key is that we have to strive through them.
Actually, capturing a few sheep alive isn't that hard. If he could garner the support of a few primitives, this wouldn't be difficult to do.
The problem is, he doesn't know how to gain their support.
