The muscular human with the goatee beside John dissolved into nothingness. That muscular human was not a summon but an offensive skill from his Fallen Apostle's Summoning Wand. This offensive skill was called Power Djinn's Smash. It dealt high physical damage with a powerful knockback force.
John learned about Beelzebub's personality from Wilted. He knew Beelzebub was a cunning devil. He didn't know how, but he knew Beelzebub would eventually think of a way to break through Trinity's Field Prison. That's why he had Trinity prepare a second Field Prison rune diagram at a nearby spot. The direction he sent Beelzebub using the Power Djinn's Smash was that spot.
Trinity immediately activated that second Field Prison rune diagram once Beelzebub fell into it.
"Hahaha!" John laughed. "Do you think someone as intelligent as I will not have a backup plan? I've already expected your move, villain! Do not think you can escape my grasp! Hahaha…!!"
