The poisonous Mandala flower tribe rules the plant world. Unfortunately, the newly born little princess Mandala cannot swallow the heavy human blood, so she cannot grow out of the poisonous nature of Mandala. However, she has a kind soul and a passionate heart. She falls in love with the Nine-Colored Deer King who lives in the Moon Spring Palace in the center of the forest. The Nine-Colored Deer King is killed. Only the poison of Mandala can break the barrier that traps the prince's soul. The princess went against her will by drinking human blood and used the poison of Mandala to revive her beloved king's soul. However, she blamed herself and asked a grass slave to use real fire to burn her into ashes. Mandala's soul was originally the daughter of the Emperor of Heaven, and she only went through the world to gain good qualities. The nine-colored deer king's soul was originally the third son of the Jun family. The two had a marriage contract, but they went through the world just to obtain firm love. Kindness and firm love make a good marriage.
