Ji Nuan didn't suggest for him to watch over the food because saying that would be an insult to the Sahara Tribe – an expression of distrust.
The Orc unconsciously touched his leg, worried that he might not do a good job.
Ji Nuan noticed his concern and said, "Don't worry, this task isn't difficult. You only need to oversee and make sure they do it properly. I'll inform the small Tribal Chief."
Ada eventually nodded and agreed. He wanted this opportunity to prove his value and let the tribe know he wasn't a useless orc.
But in reality, within the Orc Tribe, if a male is incapable of participating in hunting to gather food, it's already considered a sign of incapability.
Ji Nuan actually wanted to help this orc, but she still didn't know his character. Although he appeared to be a shy orc, one shouldn't judge a beast solely by its exterior.
