Metamorph
Both brothers, each only had a split second to try to evade. Yang Hui at least had the benefit of his agility having been boosted previously, but Yang Rong was not that lucky.
The only form of protection he had was the chi he used as pseudo armour, yet the shot was nearly a point blank. He did his best to tilt his head slightly, leading to the bullet blasting his ear off instead of his head. The pain and buzzing sound from the pistol made him stumble backwards to maintain balance and regain a sense of the current situation. The echoing of the aftermath rang in his head, the searing pain of the bullet on his skin might be too much for an average person, but he was a seasoned fighter.
Tolerating it was not an issue for him.
