The Su family was full of loyal people, and they all fled to the north. Only she, Su Wanyue, was left. In order to avenge the bloody sea, she hid her red makeup, tied up her long hair, changed her name to "Su Wan", and stepped into the military camp that was once the glory of her father and brother. After five years in the army, she relied on her life-threatening ferocity and her blood-lined military strategies to transform herself from an unknown soldier into a "Jade-Faced Shura" who made her enemies fearful. On the battlefield, swords have no eyes and dangers abound. Whenever there is a critical moment, there will always be someone who comes like a god and blocks the fatal blow for her. That person is her lieutenant, Shen Jue. Shen Jue is her most trustworthy supporter and her most tacit comrade-in-arms. It was rumored in the army that they were brothers who had died, but Su Wanyue felt something was wrong. Why did he look at her with such complicated eyes when no one was around, hiding a struggle and deep affection that she couldn't understand? Why can he always accurately predict every move of the enemy's army, as if he knows that army like the back of his hand? Until that day, when she sneaked into the enemy camp, she saw that familiar face in the coach's golden tent that made her heart palpitate. He was wearing the uniform of an enemy prince, his facial features remained the same, but his identity had been completely changed. It turns out that the most reliable comrade-in-arms is the poisonous snake that lurks deepest. It turns out that the benefactor who saved her from fire and water several times turned out to be her sworn enemy. He held the sword and walked towards her step by step, his voice hoarse: "Wan Yue, put down the sword, I will take you away." Su Wanyue smiled, tears of blood fell from the corners of her eyes, and the spear in her hand was pointed at his heart: "Your Highness, on the battlefield, you and I are our own masters. This shot is for my Su family!" It is also for... Those five years of living and dying together.
