Xu Yi's perception only extended a thousand zhang now, but using it to search underground for Ruyi Pearls was almost too easy. In no time at all, he had dug up dozens of them.

With a boom, Xu Yi felt his body tremble, and the entire earth shook. A muddy-yellow wave of light appeared ahead.
"As expected, they made thorough preparations. Looks like all our effort this time was wasted again."
Huang Mei sent him a message.
Xu Yi sneered. "It wasn't wasted. At least we figured out what's going on." He immediately sent another message to the little wolfdog, ordering it to lead the beast tide in another attack. He could see clearly that the yellow wave of light was only a protective barrier. It could repel and restrain, but it couldn't inflict damage.
Under the little wolfdog's threat, the beast tide surged again, rolling in like waves, one after another.
However, the light barrier's defense was extraordinarily powerful. It rose time and again, sweeping away the beast tide over and over.
