I think probably you need to at least 8 agility & constitution + 3 perception, so you need at least 20exp in the beginning, which, thankfully you can get even with trash talent. With those you should be able to survive the previous competitions & advance to Tang Ruo, after which I think you’ll be able to endure. When he tries to hit your leg, it won’t break, after that when you wants to hit you again you lean away from it, then you say you won’t surrender, yada yada yada. You get the gist of it.
I haven’t tried it so I don’t know. Battle sense would probably also be good to have, if possible.
