Lin Yuan, a construction-site wage slave raised in an orphanage, unexpectedly receives a letter from his parents, who have been missing for many years. It reveals the ancient ruins of the Classic of Mountains and Seas, hidden deep in the mountains for ages.
A new world opens before him. Ancient demons and primordial creatures arrive one after another, revealing a mythology unlike any he has ever known. Along with them come enormous debts and one dangerous trial after another. Follow a greedy, timid boy as he changes himself step by step and rises anew from the ashes.
The leopard, Gudiao, Dang Kang, Qiongqi, Zhulong, Black Tortoise, and Mie Meng Bird will all make their appearances. Di Jun, ruler of the Celestial Court, and the Ancestral Witches, overlords of the earth, will also awaken one by one, ushering the world into an age of myth.
At the brink of life and death, the orange cat beside him speaks: “Kid, I'm Lu Wu, guardian deity of Kunlun Mountain. Rent is ten dried fish a month.”
“That skinny dog is Hundun. It can swallow space.”
“That lame crane is Bifang. One breath of fire can burn through a building.”
“That listless monkey is Zhuyan. It fights like it has nothing to lose.”
Looking at his bank balance and the whole yard full of “ancient divine beasts” clamoring to be fed, Lin Yuan brandishes his battered Xuanyuan Sword and charges back into the fray.
“Let's see... after I lead this group of ‘former ancient powerhouses, current cute zoo pets’ to take down every enemy who comes our way and restore the complete Classic of Mountains and Seas, how much more money will I need to save?”
