Book 5 of One and a Half Feet

Pangu created the world, demons and demons were running rampant in the world, and the human race was barbaric and bloodthirsty. Saints came to the world, established sects, and preached to all living beings in the world. It enabled the human race to develop wisdom and practice, and finally drove away monsters, creating a glorious ancient age. However, after a long period of ancient times, the saint fell silent, and the prosperous age of the human race gradually withered. The monsters came back and became rampant again, constantly invading the human race territory from north to south, causing the human race's land to once again be devastated, and the mountains and rivers were broken. Fortunately, at this critical moment, a person walked out of a certain mountain, at the foot of the mountain, in a village. The man came to a river and told a story. So the demons retreated to the north again.
