In the late Liao dynasty, the Jurchens rebelled, and Emperor Tianzuo was forced to flee to Jiashan. He secretly dispatched a group of loyal and brave soldiers to transport the national treasures deep into the Khalkha steppe, burying them at the foot of Han Mountain for future use in restoring the country. As a result, various rebels and court traitors pursued the soldiers carrying the treasures, hoping to seize the treasure map. Within the Liao dynasty, it was believed that Emperor Tianzuo had died on the front lines. A new ruler was installed, but due to the rebels' chaos, the new ruler's beloved consort was also secretly murdered. General Liu Xiao returned to the capital with the treasure map, but was pursued by rebels on his way back. Fortunately, he was saved by the Mongolian warrior Dan Zeng. However, due to his severe injuries, before dying, he entrusted the treasure map to Dan Zeng, asking him to hand it over to a wise ruler. For this life-and-death commission, the villagers paid with their lives. Burigude grew up in the midst of this turmoil; inspired by the sage Namula, he accepted the mission and sacrificed a lifetime of happiness to pass down an unsolved mystery that had lasted for a thousand years.
