Zhang Chen didn't understand the power of the array, but he had the Water Droplet Shifting Technique.
Within a thousand meters, he could ignore all obstacles and teleport directly.
The reason Zhang Chen couldn't use this divine technique now was that the grand array set by the Water God twisted space, making the underground distance far exceed the limit of the Water Droplet Shifting Technique. Zhang Chen lost his sense of the small water droplet he left outside. But as long as Zhang Chen could suppress the array's core for an instant, allowing him to sense the small water droplet's presence, he could teleport over immediately.
As for whether Zhang Chen had the means to suppress this grand array for a breath?
Did you really think his Sealing Rune was for nothing?
