A certain servant, whose surname was Lü and given name Fengning, had a peculiar appetite for snake meat. Whenever he acquired a small snake, he would swallow it whole as easily as chewing an onion; should he encounter a large serpent, he would use a machete to slice it into inch-sized pieces, then cup the bits in his hand and savor them slowly.

The sound of his chewing resonated sharply, the blood staining his lips. Lü Fengning possessed an extraordinarily keen sense of smell; one time, he caught the aroma of a snake through the wall and rushed outside, where he indeed managed to catch a serpent about a foot long.

Lacking his blade that day, his mouth watered uncontrollably, so he severed the snake's head with a single bite and proceeded to devour it raw, from head to tail, bite by agonizing bite. After the head was gone, the tail still flicked lazily near his lips.
