Taking Advantage of a Lapse

'Self propelled artillery...' The idea had only just registered itself in Sheyan's mind when another shell exploded less than two meters from him. Sheyan reflexively rolled away. When he climbed back up and was ready to use some medicine to treat himself in this critical moment, a thought suddenly flashed across his mind:

'Why is the enemy's aim so precise? High Perception Sense? Impossible! There's no way they have someone who has a crushing advantage over me in Perceptive Sense. Could it be....'

Upon realising this, Sheyan immediately roared, "I wish to suppress the other party's ability with the rank of a silver party! At once!"

The Nightmare Imprint on Sheyan's chest glowed following his shout. The silver light quickly turned into countless little spots. At the same time, the light on the opponent's Nightmare Imprint faded, making it look like a stainless steel mark coated with a layer of mist. A contestant wielding a gun immediately yelled in anger.
