In the 155th year of the Holy Ming Calendar, the bloodline of Emperor Quan used unknown power to create seven pieces of divine jade and sealed them in seven palaces. It is said that the gathering of seven pieces of divine jade is the key to unlocking the dragon's veins. This powerful unknown power is hidden in the dragon's veins.
Wherever the sacred jade is sealed, there are guardian beasts guarding it. The Eastern Palace is guarded by the Azure Dragon Divine Beast; the Western Palace is guarded by the White Tiger Divine Beast; the Southern Palace is guarded by the Suzaku Divine Beast; the Northern Palace is guarded by the Xuanwu Divine Beast; and the "Dark Abyss" in the center is guarded by the Divine Dragon and Divine Phoenix. It is said that one can unify the world by gaining the power from the dragon's veins. In order to obtain the Seventh Palace Divine Jade, various forces in various countries are constantly arguing and undercurrents are surging. The indifferent young king also embarked on this road of killing for a certain reason.
