If you're talking about manipulating Natural Energy, I don't think Jugo can do that, because he didn't train in the Sage Arts.

So to answer your question, I don't think Jugo can fight forever, because he needs to recharge after he uses up his chakra, unless there's someone near him that he can absorb to replenish his chakra. Well I don't know about that considering he is literally born to be good at controlling natural energy and is pretty good at controlling it tbh the only reason he goes insane is because he keeps sucking in nature chakra and sense he can't turn into an animal or turn to stone his body goes berserk to get rid of some of that energy not to mention he is basically training his experience in natural energy/senjutsu by simply being alive and I imagine he could use natural energy to keep fighting rather than relying on chakra as well Idk I could be wrong
