Continue the great cause of the original owner as a "spy" and marry into Prince Jing's palace to become an unfree princess; Second, stay anonymous and live her life again. She thought about it for five seconds and quickly chose the latter. Carrying sandbags, rescuing hostages, drawing blueprints, making weapons, killing enemy troops, defending the city... When she became successful, the husband of the original owner suddenly said to her with a token: "Welcome back, my princess!" Sang Yun suddenly panicked! Her grassroots background and the shadow of her original family in her previous life made her suddenly resist the approach of that man... ——Sang Yun: She has always been asked for, but she almost forgot that she also deserves to be given. [Introduction to the male version] Before the age of fifteen, Mu Chen was recognized as the proud son of heaven. After a great change, he fell from the sky and was exiled to the desolate north. The swords of the past are gathering dust, and the galloping horses are being kept in captivity and destroyed. Externally, he is a fallen prince; internally, he is a politician who is well versed in calculations. In the life and death/ups and downs, he threw away his sword, picked up conspiracy and calculation, and finally became the kind of person he hated the most! Until one day, someone picked up the sword in his hand and said to him: "From now on, I will fight for you to kill the enemy and protect the north!" After years of boring life, there seems to be hope. ——Mu Chen: I'm sorry that I couldn't let you see me at my most energetic.
