Don't move, move and you die (3)

A middle-aged man was drinking and eating meat when suddenly, he spat out a mouthful of fresh blood and collapsed straight to the ground.

"Sir!" The woman opposite him was startled. "What's wrong with you?"

"Pei Zhen, a Master of Yin-Yang has arrived in Lin and broken the array I set up for you over a decade ago," the man said, his complexion ghastly. "Clever fellow, to find every single point I set. The array is now useless, and the backlash has hit me."

Pei Zhen's face paled, anxiously, she said, "What do we do now?!"

Just as Pei Yan's branch of the family was about to completely fall from power, how could someone break their array at this critical moment?

If the array was broken, wouldn't that mean Pei Yan could rise again?

Wouldn't her decade of endurance and scheming be in vain?
