Chen Xun was about to start singing on the road when Black Bull suddenly indicated it needed to relieve itself. He frowned instantly, what the heck?

He stared at Black Bull by the roadside. The latter looked uncomfortable, holding it in for a long time, its black face turning red. Chen Xun squinted slightly, feeling more and more that something was off.

He took steps, moving closer to the tree where Black Bull stood. Grabbing its ear, he softly sang, "Listen to me..."

"Moo!!!" Black Bull's face showed fear, letting out a horrified scream, and finally, a thunderous fart was released.
