Zhang Yufang, everyone called him a monster and a demon, because he was born with an emerald green right eye and a blood-red left eye.

From birth, he was called a baby born of a curse. His late father, Duke Zhang, was a former warlord who commanded tens of thousands of soldiers. However, behind his immense prowess on the battlefield, he had a pact with the devil. Until the birth of his second child, Zhang Yufang had to accept the curse.

Dozens of years have passed, and he has become a god of war, capable of cutting down hundreds of heads with a single swing of his sword. All those who once gossiped about him now dare not even mention his name, for he is a cruel and bloodthirsty god of war, and the child born of a devil's curse.

Today is the day of his return from the battlefield, he rode his horse gallantly on the road to the duke's residence, since he was 3 years old he had to wear a mask to cover his eyes which was considered to bring bad luck to those who looked into his eyes, and until now he still wears it.

The empress and the emperor have three children: the first is the crown prince, the second is the fourth prince (the emperor also has several children from his concubines), and you are the fourth princess among all the princesses in the kingdom.
