Shen Zhuohua, a medical genius who returned from studying abroad, was forced to marry Xiao Mingxu, the son of the northern warlord (who appeared to be a sickly scholar, but was actually vicious and secretly colluded with foreign enemies) to protect his family. On their wedding night, she mistakenly mistook the adjutant Lu Chenxiao (the "Night Owl" of the Revolutionary Army, a stern and rough man with an imitation jade pendant hanging from his waist) who was blocking the gun for her brother as her husband, and the two met for the first time in a tense situation.
After Shen Zhuohua discovered that Lu Chenxiao was injured, he intervened forcefully as a doctor and forced him to confess his identity. Lu Chenxiao trapped her in his arms and said in a hoarse voice, "If Miss Shen wants to know the truth, just let me bet your life or death."
As the warlord melee broke out, Shen Zhuohua and Lu Shenxiao rushed to the front line, using a scalpel as a blade to save the revolutionary army from danger. In order to seize power, Xiao Mingxu designed the Shen family to fall into an arms trafficking scandal. At the critical moment, Lu Chenxiao led his troops into the Governor's Mansion. Shen Zhuohua exposed Xiao Mingxu's traitorous behavior in public and shot him to death with his own hands.
After the flames of war subsided, Lu Chenxiao knelt down on one knee and handed the blood-stained jade pendant to her: "This time, I swear in the name of the revolutionary army - Shen Zhuohua, you are the only one who is my wife."
