Yu Yang reincarnates from 21st-century Earth into the Primordial Continent. The continent is divided into four lands, east, south, west, and north, each with nations both large and small. So far, the Eastern Continent, where he lives, has four dynasties, three great sects, four religions, and a mysterious Wu Clan.
The dynasties are the commercially prosperous Tang Dynasty,
the Fang Dynasty in the north, renowned for its military,
the agricultural Han Dynasty,
and the flourishing Song Dynasty of scholars.
The three great sects are Buddhist, Daoist, and Confucian.
The four religions are Beast, Ghost, Demon, and Monster.
The Forbidden Mountain Range is the largest forest on the continent. The Primordial Beasts gather in its heart, while the pit where they live is an inconspicuous place. According to the Third Elder, they were forced to take refuge there. Since arriving, they have never seen a giant beast. A great banyan tree grows in the pit, and the evil beasts of the forest have never gone near it.
Before reaching adulthood, Yu Yang fails to attain the strength of a clan leader, so he sets out to gain experience alongside the other children coming of age.
In the Fang Dynasty, he rescues the young daughter of a fox woman and raises her. He names her Xueyan.
To avoid the scrutiny of the secular world, he has no choice but to set off on a long journey with the young Xueyan. While in the Fang Dynasty, he gets trapped in the Demon Venerable's inner world and obtains the ancient treasure, the Mountains and Rivers Map. He also fulfills his promise to find someone for the Demon Venerable.
When he returns to the present world, the wheels of fate begin turning again. The world will be baptized in blood, and immortals, humans, monsters, and demons will face a new order.
