After Dressing up as a Silly Princess, the Whole World Wants to Kill Me

In the past life and the present, the one who broke the situation returned to his position - once the silly princess awakened, she stirred up the world. The modern Song Xuanning accidentally traveled into the body of Zhao Xuanning, the princess of the Song Dynasty in the previous life. When she woke up, she found that she was about to be sent for marriage and was being hunted. Where should she go in the face of this troubled world... As a princess, she traveled across the court, using the enemy's sword, the prince's power, the general's soldiers, and the master's wisdom to make Liao, Song, and Xia put aside centuries of war and conclude a treaty of peace. When there is peace in the world, whose hand will she hold? Is it an enemy secret guard who has transformed from an assassin to a sword that protects her? Is it the cold-faced prince who made an exception for her? Is it the master who is cool and self-possessed, but his sword is messed up because of her? Or is it the bond between two lives, the childhood sweethearts who have been together for thousands of years? I have the final say on my affairs.
