Yuan Yao immediately turned around to assign his people, and dozens of them split up to flank from both sides, looking for a suitable location to lie in ambush and get ready.
Once everything was in place, the "Green Soul Refining Rainbow Sword" on Gu Lianni's back suddenly turned into a cyan rainbow that shot up into the sky, then like a meteor, it slammed towards the iron forest.
There was a thunderous roar, the sky and earth shook violently, and dust shockwaves spewed out in all directions; that one sword strike seemed as though it pierced through the steel ground.
People on the ground trembled, their entire beings vibrating, staggering in their steps and looking around in panic.
In a short while, Xu Anzhang and others underground ran out one after another, their faces having changed color; caught off guard by the attack, their ears almost went deaf from the shock.
