28.16

The Shanxin jing also states: There is a divine medicinal tree named moluotuoji, which is sovereign in suppressing all the ten thousand poisons under heaven, preventing them from acting wildly. There was a great divine serpent, one hundred and twenty spans long. The serpent traveled looking for food. There was a black-headed worm, five zhang long. The worm, traveling on the road, encountered the serpent. Just as the serpent was about to raise its head to bite the large worm, it smelled the medicinal fragrance and bent its head, wanting to flee. The serpent's body brushed against the medicinal tree, and its body snapped in the middle, breaking into two pieces. The head half fled alive, while the tail half rotted with a foul stench. When all poisons smelled the stench of this serpent, the evil poisonous vapors of all of them were entirely extinguished.
