There was once a world where humans and spiritual beasts coexisted harmoniously.
Spiritual beasts do not have any ill intentions towards humans, and will help humans from time to time to solve the problems caused by droughts, floods and earthquakes. In this way, humans develop technology under the protection of spirit beasts, and reward the spirit beasts with technology, giving the spirit beasts interesting new experiences.
Later, human science and technology advanced by leaps and bounds, and the existing resources in the world were unable to support human beings' continued development or even meet their daily needs. Human beings had to find new energy sources.
A few years later, a research institute invented a device to extract and use spiritual energy.
In the same year, several small spirit beasts were captured.
Human beings use the spiritual power stolen from spiritual beasts to maintain their daily energy supply, but they still want more.
The remaining spirit beasts fought hard and fought with humans for a long time.
In the end, humans won the battle, and used the spiritual power conversion device to leave this scorched world, and built a floating city that only belonged to humans out of sight.
Later, humans discovered a way to use spiritual power on their own, and began to transform and cultivate people who could use their abilities on their own. In a place called Yuling City, the leader who is in charge of all matters in the city calls these people - Yulingmen.
After an unknown number of years, the Yulingren broke through the limitations of the world and began to search for and capture spirit beasts from other worlds.
At this time, the spirit warriors relied on the power plundered from the spirit beasts to defeat the spirit beasts they had feared thousands of years ago, and walked on the road destined to destruction.
