LUO YAN was still wearing his [Invisibility Cloak]. So, the fact that Luo Jin was pointing his guns at him so accurately meant that the other could see him. That's when he noticed that his brother was wearing a pair of glasses with blue shades, completely different from the other's [Snipe Lens].
It's easy to guess that these glasses were the reason why Luo Jin could see him right now. It seemed that this brother of his really prepared a lot just for this fight. No, the other obviously had already been prepared even before it was decided that they would be the ones fighting at the finals. Which only showed that even before, Luo Jin was already expecting for them to be the ones remaining in this tournament.
Well, Luo Yan was also hoping for this result. But this was literally not the time for him to think about that. Especially when two bullets were about to put a hole on his forehead.
