The Manluo, Tianjin, and Sinan tribes live next to each other and fight against each other.
As the guardians of the three clans, the dragon clan has protected the stability of the three clans for thousands of years.
As the empress of the Manluo tribe gave birth to Princess Baihua, Master Xuantian asserted that this girl would save the Manluo tribe from water and fire decades later. The Manluo Tribe's treasure, the Pearl of the Sun, is the most sacred object in the world and has been coveted by the Tianjin Tribe and the Sinan Tribe for thousands of years. When Princess Baihua was five years old, the Manluo tribe was suddenly attacked. The Lord and Queen died tragically, and the White Pearl was missing.
Decades later, in order to maintain the relationship between the three clans, Princess Baihua was arranged by her elder brother to marry the prince of the Tianjin clan, but she did not want her sister to have a man she had loved for many years. This man was none other than Bai Ze, a boy from the Dragon clan.
However, the Dragon Clan made a rule thousands of years ago that they are not allowed to marry people from the Manluo, Tianjin, and Sinan Clan.
On the day when Princess Baihua and the prince of the Tianjin tribe got married, the eldest prince of the Tianjin tribe was waiting for an opportunity to usurp the throne. The imperial tomb that had been closed for thousands of years by the Tianjin tribe was destroyed, and the big ghost who guarded it came out of the stone and threatened the world.
Manluo, Tianjin, and the Sinan tribe join forces to fight against the big ghost.
But he didn't expect that the big ghost was wreaking havoc among the three tribes, and those injured by it became blood monsters, including the princess Ji Ray of the Tianjin tribe. Ji Ray develops feelings for Bai Ze while the Dragon Clan is recuperating.
At that time, Princess Baihua and Bai Ze, under the guidance of General Nangong, searched for the three Dragon Carved Stones of the Dragon Clan, and went to the Eternal Life Gate before the Day of Thorns to find an antidote that could remove the toxin of the big ghost.
However, the Dragon Carved Stone was in the hands of three guardians who had retired thousands of years ago. Princess Baihua and Bai Ze had been unsuccessful in searching for the third guardian. Through various events, Princess Baihua suddenly discovered that the third guardian was probably someone beside her, and the birth of a big ghost to harm the three clans was related to a grudge that happened thousands of years ago...
Purpose: The boy from the dragon tribe and Princess Baihua work together to subdue the big ghost for the sake of the stability of the three tribes.
