Keeping pressure over the incoming masters from the outer world was the best situation for this world master.
William knew he could end the formations in less than five minutes. But he wanted to make sure he had enough time for any unforeseen event.
Sounds of fierce explosions and attacks landed all over the place. And the more time passed, the harder the situation became.
It wasn't rare now to see a few masters penetrating through the defensive line, approaching the area where the formations were laid down, and attacking masters there.
But whenever they'd come this close, they'd end up getting massacred by the strongest masters like Fang and Sloth. Even so, William knew they had little window left, and he poured everything he had into finalising the formations.
"It's ready!" At last William shouted the thing everyone waited for, "activate the formations!"
