Can I Still Survive with a Prehistoric System?

What to do? I traveled back to the prehistoric era, and there was a deer covered in flames in front of me, staring at me, and behind me there was a wolf covered in ice, drooling. Brother, I'm just passing by, so keep playing, ah! You don't talk about martial arts... What? I have a system, but I want to give him a prehistoric system. I think I can do it, so do it.
