Once, because of a pair of purple eyes he was scorned. He is a wangye known across the land, cold and bloodthirsty, looking disdainfully upon the world.

A frown that is enough to make the room's heavy. “As a teacher, you think I would leave you unpunished?”“You seem to think that I care about your position, Prince Hermit. But believe me,” Draven took a slow step. “Not even your father could protect you from me.”

“Mr. Xu, are you really a Heavenly Master?”

“As genuine as they come, more real than gold!”

“I’ve heard that your reputation in the supernatural circle is really bad, even to the point where a ghost once called the police saying you were threatening him?”

“Impossible!”

“It wasn’t me!”

“Don’t talk nonsense!”

Xu Yang clenched the Thousand-Year Peachwood Sword in his hand, and said, “What’s the name of that ghost? Would you dare to let him confront me face to face?”
