In the Age of Declining Dharma, extraterrestrial demons descend, and humanity is powerless to resist. By chance, the young Xi Yaqiang and Su Zhengyang inherit the ten thousand pigs passed down through their family. To their amazement, they can use pigs as soldiers, feed them swill, charge into battle astride them, and even refine war pigs into pig-shaped armor. As humanity’s cultivators are driven back at every turn, Xi leads an army of hundreds of millions of pigs to crush the Demon Abyss. The myriad races hail him as the "Pig-Raising Emperor."
