When Quinn heard Mundus say he was going to give him some information on his opponent, he was expecting to get a few tips. Maybe something about what his opponent could do, his strengths, anything to help him with a fight.
Not to hear his back story and cause him to feel empathy for this person. Now he needed to shake his head and convince himself that he was fighting against someone who he wanted to beat. Thankfully the reaction of the lives on the planet made it easier to do that.
'It's safe to say if I'm in trouble that Mundus won't help me out, so let's do this!' Quinn thought.
Using the blood guns, Quinn started to fire more bullets once again, and was switching up with every type of bullet he had, blood bullet, god slayer, shadow bullet and so on. With his quick reflexes and great eyesight, he would be able to see what bullet was most effective.
