Under the Battle Flag, I Am Your Most Painful Knife

Main plot: Lin Wanzhao, who was born as an Orion hunter, joins the Northern Army and becomes the scout captain after rescuing General Shen Jinghan who was ambushed by the enemy. The two fall in love with each other while fighting side by side. However, the enemy country made a truce on the condition of peace, and the emperor forced Shen Jinghan to marry the enemy's princess. In order to protect the peace of the border, Shen Jinghan pretended to compromise, but was misunderstood by Lin Wanzhao as being unkind. Lin Wanzhao was frustrated and asked to fight to defend the border. After being besieged by the enemy and running out of food and supplies, the two resolved their misunderstanding when Shen Jinghan rushed to help, but were forced to separate due to the emperor's suspicion. Later, the enemy came back and Lin Wanzhao was captured. Shen Jinghan risked his life to save her and confessed his feelings. When the two of them worked together to defend against the enemy, the city fell. Shen Jinghan protected Lin Wanzhao and was injured and fell into coma. Lin Wanzhao took charge of the army and repeled the enemy. However, due to the poisoned wine given by the emperor, Shen Jinghan was killed for resisting the order. Lin Wanzhao took their children to live in seclusion. Before his death, he passed the battle flag to his children to continue his belief in protecting his family and country.
