540 Alarmed

Standing on a cloud at a high altitude, Black Wing asked, "How long will it take to make the entire Great Chang world impregnable?"

"Seven days should be sufficient."

Among the five half-step Ancestral Fiends, a man with a snake's tail said reverently, "Many of the array formation artifacts have long been refined. All we need to do is put them in place. In fact, it's possible to make the various array formations stable in five days. Seven days will just ensure that we can sufficiently set up all the array formations as Patriarch instructed."

"Alright, set it up as soon as possible. Remember to remain concealed. Do not be discovered by the two Green Touring Palace disciples in the Great Chang world," instructed Black Wing. "Should we be discovered, it will be troublesome if a large number of Green Touring Palace immortals descend upon us."

"We understand," replied the five half-step Ancestral Fiends.

"Go on." Black Wing waved his hand.
