The beggar Ye Tian is bitten by a burrowing snake while digging for wild vegetables and unexpectedly gains a snake clone that can share his five senses and retrieve objects from a distance. He becomes wealthy by digging up antiques and spiritual herbs underground. The snake can also collect rare treasures of heaven and earth and gradually evolve into a dragon. Ye Tian finds treasures such as a Nine-Leaf Lotus and Thunderfire Bamboo, outsmarts local bullies, rescues a princess, and auctions off a Dragon-Phoenix Jade Pendant and a Martial Emperor Sword for a million taels of silver. After collecting the final ingredient, Dragon Abyss Grass, the snake successfully transforms into a dragon and promises to take Ye Tian and his mother on the path of cultivation and ascension to immortality.
