Actually, Xu Huo should have used auxiliary tools long ago, but considering this might be the domain of Super Players, and perhaps Players from Zone 011 might come to the rescue, whether it's Cubic Space or Angel's Eye, taking them out carries certain risks. He's been holding back, but after trying every possibility and failing to find more patterns, he has no choice but to take the risk and give it a try.
Since this field is related to time, he simply closed the door and took out the Angel's Eye.
Starting from when he first appeared in the Chaotic Space of Zone 014, Xu Huo began evolving towards Time-Directed Super Evolution. So far, his evolution only allows him to sense Time Rays; he still can't control them to do anything, unless he's in a special environment and aided by props.
Angel's Eye is just such an auxiliary prop—a natural mineral that can release Time Rays, its embedded black ring making Time Rays easier to manipulate, such as intercepting a segment of time.
