On the night of the Yuan Dynasty, the poor scholar Xiao Chengyu and the businesswoman Tang Wanwan met because of the "Double Crane Picture". Half of the Luanhuang jade pendants they wore coincided with the starlight, revealing the fetters of fate. Xiao Chengyu is involved in an old case of imperial examination fraud, and Tang Wanwan becomes the focus of competition in the Tianji Pavilion because of the jade pendant left by her mother. The two are forced into a desperate situation by the powerful minister Yang Mingyuan - he privately forges weapons, monopolizes the salt administration, and attempts to use the stars to rebel.
One can draw with a pen and protect the people with a sword, while the other makes business decisions with a bead and breaks the situation with a silver needle. From the first meeting at a painting stall to the back-to-back resistance against the enemy: he breaks into the household department at night to search for evidence, she cleverly devises a "Hui Min Salt" to break up the monopoly; When the abacus of business and the advice of the court are intertwined, they use love as their armor to break through the whirlpool of power and conspiracy side by side - the two cranes flap their wings, not for fate, but just for the sake of holding each other in the palm of their hands, protecting the common people and each other.
Let's take a look at how this pair of lovers, who are masters of pen and sword, create a legend of "dwelling in the world" amidst the turmoil.
