When the world was created, a fire dragon betrayed the world and the world became dim. After three years of war, the fire dragon was sealed under the Mulberry Mountain. There is a holy spring on top of Mulberry Mountain, and under the holy spring is the fire dragon. A phoenix team suppresses the fire dragon here to ensure peace in the world. Thousands of years have passed, and most of the people who knew about this are no longer there. Only Lao Wutong, the Dragon Lord in the sky, and Master Cihang who lived in the mortal world were lucky enough to survive the war.
The seal is on the downloaded phoenix. The selected phoenix will be born with this seal. This phoenix cannot leave Mulberry Mountain, otherwise the fire dragon will be in danger of breaking through the seal.
Thousands of years have passed, and the people in the valley have long forgotten this matter, or because of a tacit understanding, they have never mentioned it. Generation after generation, only Lao Wutong in the valley still remembers this matter.
In this way, it is the phoenix with the seal.
Phoenix was not allowed to leave the valley, but this order was continued, and somehow it became that no one was allowed to leave the valley. Gradually, as they got used to it, no one thought about leaving the valley. There is a cloud at the entrance of Phoenix Valley, which serves as a barrier for ancestors to prevent outsiders from breaking into the valley.
