Story seems dumb and it's only chapter 2. Why shoot her and get so worried about her biting some pill?
Even if it's some nerve agent it's not that reliable. She should use explosives or similar to kill them.
Dude just buy USD100 or more worth of bitcoin when they come out. 10 years ago 10,000 bitcoins were going for about USD40. Now that's worth USD318 million.
It might be tougher for the first few years but after a while you can spend a million a year and still be fine.
If she's strong enough to break a mithril sword, she should be able to kill most stuff just by throwing cheap stuff at them. Just needs to improve her accuracy.
If time-stopped stuff had the consistency of stone he wouldn't be able to kill them the way he does or tie them up (e.g. the assassins). Same for their clothes, they clearly can be flexible to his touch.
Uh, how is the MC getting beaten so badly? He just caught a blade with his mouth and bit through it. Don't tell me biting an arm or fist is harder.
Even if the MC has to get hit by 3 punches to deal a claw or bite attack he'll win.
Don't try to fist fight bears. Get a good weapon if you can.
Guess the MC is a crap fighter. The MC has two arms with claws and an OP mouth that can bite through steel... How'd the MC get beaten up so much by a guy who is mostly just boxing and doing nothing fancy.
That's one way to have repeat customers:
Customer: "Uh your arrows had way too much penetrating power! After hitting their targets they even went right into stuff like tree trunks. Half the time I couldn't find or retrieve them anymore!"
MC: "Sorry! I'll try to make blunter ones"
Customer: "No...
LOL, there's nothing but plot armor preventing the beastmaster villain from losing to someone with the MC's abilities. In fact the MC should resurrect the guy at least a few times, after all a quick death is too merciful for someone like him.
