Confirmation

Within the Sky Swallowing Sanctuary, in a secluded territory. 

"Jian Wushuang has already left the underground palace and ordered the experts to go to the human territory." The elderly man said coldly.

"What about the palace?" Ba Su asked.

"According to the intel that Acheron Palace received, Jian Wushuang has arranged for several experts to guard the palace and given the order that none shall attempt to enter." The elder man said.

"Humph. As expected, it is impossible for him to refine that sacred weapon. He is not dumb so he gave up after trying for eighteen years. If he can't refine that weapon, he won't be able to bring it out of the palace. All he can do is leave the weapon there and protect it." Ba Su smiled.

"That seemed to be the case." The elder man nodded his head.

They did not suspect anything at all.

After all, the weapon was the Soul Swallowing Pearl. Who could refine it within eighteen years?
