"Your Majesty, there are nine arrow holes here!"
Zhang Sanfeng pointed at the mural, stroked his beard, and smiled, "This is a type of mechanism. The Chaos Sky-Piercing Arrows that General Xue acquired are the keys to activating the stone wall; otherwise, we'll just have to wait for the formation's energy to deplete!"
Upon hearing this, everyone's faces lit up with joy.
The formation on the mural in front of them was also dim, and it wouldn't take long to completely disintegrate.
But if they remained stagnant and wasted time, they would be caught up by the later arriving prodigies of other races.
By then, the hard-won advantage they had gained would mean nothing.
"General Xue, quickly insert the Chaos Sky-Piercing Arrows!"
Qin Wudao ordered.
"As you command!"
Xue Rengui stepped forward, and nine Chaos Sky-Piercing Arrows shot through the air, precisely landing in the nine arrow holes, emitting a resplendent divine light and unleashing terrifying arrow intent.
