This Taoist Master is too Frivolous

"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?"
