The world is divided into three realms: humans, demons, and immortals. The three realms meet and support each other. No one from the three realms will interfere with the fate of the other two realms unless necessary. Besides the three realms, there is another realm called the illusion realm.
The fantasy world is a gathering of the top villains from the three realms, a group of people who do all kinds of evil.
In the human world, there is a prosperous dynasty - Daxia Kingdom.
Gu Rongan was the fourth prince and the future prince of the Great Xia Kingdom. He grew up in love, was surrounded by the world, loved by his mother and concubine, and pampered by his father. He was the best among the princes in talent, learning, and strategy. Everyone said that this son was born to be emperor. The mother-in-law is the emperor's favorite concubine, named Tang Qingrong. Although she is the daughter of a general, she is dignified and gentle.
Ji Lanxing, a long-lived national master of the Daxia Kingdom, was originally the young prince of the Phoenix clan in the demon world. However, he was deceived by Gu Lanyue, the founding emperor of the Daxia Kingdom, into this deep palace because of his young age. He was trapped in this deep palace and was forced to divine and read the stars for the Daxia Kingdom and teach the princes of Daxia Kingdom the art of imperial power.
Does Ji Lanxing hate the Daxia royal family? He hated it, but he couldn't escape. He had given up on his own people. He had nowhere to go. He hated it at first. He wanted to kill Gu Lanyue's descendants. But when he looked at the children with sunny smiles, he couldn't do it. The one who trapped him was not these children, but Gu Lanyue. He should blame Gu Lanyue, blame Gu Lanyue for being unkind, blame Gu Lanyue for deceiving him...
Gu Rong'an has been with Ji Lanxing since he was seven years old. Ji Lanxing always looked indifferent. Ji Lanxing taught him the art of emperors, stargazing and interpretation, and benevolence, justice and morality. Gu Rongan liked this teacher very much, until the palace change...
When Gu Rong'an was 17 years old, Concubine Jing's mother's family launched a palace coup. The emperor was afraid of Concubine Jing's mother's family, and secretly ordered to be ready to remove Concubine Jing's mother's family at any time. The Tang family was heartbroken. In order to protect themselves, the Tang family initiated a palace coup in an attempt to force Gu Rong'an to the throne to protect the Tang family. Ji Lanxing held a long sword in his hand and penetrated the concubine Jing's neck with the sword. Gu Rongan rushed to the hall and only saw his master's sword penetrated his mother's neck...
Gu Rongan couldn't care about anything and seriously injured his master with his sword. After that night, Gu Rongan ascended the throne. Ji Lanxing was still the national master, but he started to shut up and not see guests...
