Liu Mang followed Lan Qingyuan away from the medicine hut and sprinted all the way to the peak of the back mountain.
At the mountain top, Lan Qingyuan stopped, set down his wine gourd, and tore off his upper garment, "Look at my chest."
Liu Mang looked over and saw nothing unusual about Lan Qingyuan's chest.
But after a little while, Lan Qingyuan's chest began to change, gradually revealing the outline of a face, followed by a complete human face.
A woman's face, grim and terrifying, and exuding a dense and malicious aura.
Liu Mang furrowed his eyebrows, staring at the human face on Lan Qingyuan's chest, "Master, what is that?"
Lan Qingyuan said, "The Human Face Gu!"
"You've been poisoned with Gu?"
"Yes, I've been poisoned for over twenty years now."
