Fantasy: Because I Was Too Afraid of Death, I Focused on Defense at the Beginning

I, Lin Shou, traveled to a fantasy world and became a handyman of the Qingyun Sect. The system asked me to choose a profession, and I chose the most physical training without hesitation. I added all attribute points to defense, and the result panel showed: [Defense: (???)] I thought I was going to be beaten as a punching bag from now on, until that day, the eldest brother, the most talented person in the sect, pressed his sword as sharp as clay against my throat. He smiled ferociously and tried harder, but heard a crisp "clang" sound. The sword is broken. I touched my neck, which didn't even have a white mark, and looked at the stunned Senior Brother and the silent people in the audience. I seem to have clicked on the wrong attribute? This is not a defense, this is to avoid injury!
