William peeked above the staircase, then quickly ducked down just in time to hear a spray of arrows whizzing over his head and hit the ground nearby.
He looked up at a diagonal to see over a thousand crossbows lining the ceiling of the tenth floor, likely powered by Arrays as they focused in on his position.
William instead focused on his Navigation Talent to survey the room, seeing as there were too many crossbows.
A circular stone wall was in the center of the room, protecting the pedestal that was already raised. William could see the black box seated on the pedestal, and a few other structures underground just a few meters away from the pedestal.
He conjured a small rock with the Earth Element, then threw it over his head in the direction of the pedestal. The rock hit the ground and tumbled for a few meters. The crossbows fired arrows at the rock while it rolled, causing it to trigger additional traps that were hidden underground.
