A long, long time ago, people were pursuing the way to become immortals and live forever. Some people and animals really achieved immortality through practice. However, the immortality of the world brought disorder, so the "immortals" took precautions and established the "Luo Domain" to separate ordinary people from those with powerful magic and immortality. But there was only one person who was unwilling to leave, she was Ling Xiao.
Crane Yi is a willow tree in Luoting. After practicing for 500 years, he came to the mortal world to repay his kindness and settle his relationship with his benefactor. In the end, he became a devil in people's mouth and was suppressed by the four divine beasts of Luoting. This is what the world thinks, but they don't know that he is alone in a prison. His good self imprisons his evil self on the island.
The four mythical beasts are Suzaku, White Tiger, Celestial Silkworm, and Black Snake. When they come to the mortal world, they must first choose a host and make a contract with the host. The power of the mythical beasts can make the host stronger and possess different levels of mana. The lives of the four chosen sons are thus rewritten, which is both joy and sorrow.
The world has returned to peace, but there are still evil spirits who try to use the power of the mythical beast to dominate all things. How should the mythical beast choose, whether to maintain the contract or leave the host.
Intention: friendship, love
