Retreat!!!
That was the case in the underground city, but here it was different. So William didn't care about any of that and kept doing his task until everything was ready.
"Let's do it," William came by Sloth's side and took the crystal from him in one hand, while the other held a group of grenades, "Make sure the moment the gate is open to jump into it. Don't care about anything else, got it?"
"Take care of yourself first!" Sloth harrumphed while waiting to see how William was going to activate it. He already heard about the way to activate this crystal from other city leaders and high-end masters who were close by when two monster gates were summoned.
He thought William would do something else, but he just slammed the crystal to the ground, while waving the grenades randomly around. He didn't need to target anything with them, knowing that the moment these grenades got detonated, others would catch fire as well and explode.
