It's My Victory
Arthur expected to have a clash with the dark angel grandmaster once he passed the hole. But he never expected to find himself trapped inside such a scary portal, a portal linked directly to the higher realm of that enemy.
This meant he was on the losing side here. The enemy wouldn't let him go unscathed from this clash and would come fiercely for his life.
That was why Arthur didn't hesitate to think of the most brutal way to crush this portal. He didn't aim just to escape, but also to inflict some damage to that hard enemy.
In front of his eyes, the black curtains were summoned. Portals of Gege didn't last more than five seconds here, but it was enough to let the curtains pass through and float in the middle of the portal.
As for triggering these ticking bombs, Arthur wasn't worried about that. He trusted his enemy to attack anything he threw at him, and that was what happened.
