Su Sanxian looked at Wu Tao, Gu Xingyuan, Ye Chaoming, and Jin Cha, then continued, "If the Three Realms merge, the Boundary Wall Battlefield will no longer be able to stop the Devil Race's invasion. You can imagine that, with the Devil Race's warlike nature, once the World Barrier's shield is gone, the Devil World will certainly invade our Star Sea Cultivation World on a grand scale."
"So we must seize the time to prepare for war. Only when the World Barrier disappears will we have the strength to withstand the Devil World's full-scale invasion."
Wu Tao and the others understood Su Sanxian's words. They could also foresee the World Barrier vanishing and the Three Realms merging. The Devil Race of the Devil World would certainly not remain peaceful.
