After confirming the siege of Jade Dragon Sect in a month, Xuan Yue Hall started its preparations. Normally, dealing with an affiliated force doesn't require much preparation.
But the current Jade Dragon Sect is different. It's clearly a trap, and along with Chen Lu's claim that Jade Dragon Sect has two Evil Immortal Monarchs, and no one can predict how many Immortal Monarchs the opponent will send, attacking Jade Dragon Sect must be done with full effort and without any oversight.
Before attacking Jade Dragon Sect, Ling Yin Immortal King sent numerous disciples to investigate Jade Dragon Sect's deployments.
Since it's confirmed to be a trap, the opponent will definitely set up some formations. It is necessary to figure out what arrangements have been made by Jade Dragon Sect to reduce casualties.
