It wasn't that Great Elder Yun had failed to think things through and simply forgotten to protect the ancestral tombs.
The Five Finger Strange Peak where the ancestral tombs lay already had the strongest defensive formation. As long as the heavens didn't collapse and the earth didn't split, the formation was guaranteed to hold.
That was why, during this entire encirclement, Great Elder Yun had never worried that Xu Yi would attack the ancestral tombs.
Even now, Great Elder Yun still couldn't figure out how Xu Yi had broken through the iron curtain around the ancestral tombs.
He knew Xu Yi had captured Yun Zhongge, but even Yun Zhongge couldn't open the ancestral tombs' forbidden formation.
Great Elder Yun had thought so hard his head was about to burst, yet he still had no clue.
As it turned out, the Yun family's Great Elder had arrived in such a hurry that he hadn't gotten all the information.
For instance, today Seventh Elder Yun had summoned the sacred tablet to represent the Yun family and receive the bows of a newlywed couple.
The matter was neither particularly important nor trivial. At the time, the Yun family's Great Elder had been secluded deep within the palace, and naturally no one had dared disturb him.
Thus, the Yun family's Great Elder knew nothing about it.
By the time he made his appearance, all he had heard was that the Yun family's core forces had been wiped out.
He had come here in a hurry to kill Xu Yi and avenge this blood feud. He hadn't even entered Yufu Palace, so how could he have paid any attention to the sacred tablet?
Even now, he still didn't know that Xu Yi had snatched the sacred tablet, which the Yun family regarded as its lifeblood.
