The dragon lurks in the abyss to support the emperor's cause, and the tiger's roar revives the mountains and rivers; once the storm is overturned, the world is shocked when the dragon and tiger move.
They have different surnames, Wang, and their two daughters have the talents of dragon and tiger. Is destiny a blessing or a curse?
