Start practicing from marrying the disfigured princess

Ren Pingsheng traveled through the Great Zhou Dynasty, bound the system, and signed in at the capital to get rewards.
But because of his identity as the prince of Zhenbei, he was trapped in the northern border and failed to sign in once for twenty years.
Until this day.
The emperor sent an imperial edict to the northern border, ordering the prince to go to the capital to marry the disfigured princess...
Just when everyone thought he would refuse.
He resolutely embarked on the road to the capital!
…………
Many years later.
Looking at his own beautiful wife, he turned the world upside down.
The prince said: Actually, at the beginning, I just wanted to get a sign-in reward.
