She, Xu Tang (Shen Ran), is a modern undergraduate nursing student. She is an intern in the obstetrics and psychiatry departments of a tertiary-level hospital. However, she died suddenly due to overwork and became the legitimate daughter of the official minister of Dajing.
The original owner commited suicide due to being disgraced by falling into the water and being humiliated by the breakup of the engagement, leaving behind strife in the house and rumors throughout the city. Facing this era of vacancies in medical care and frequent maternal casualties, she is determined to make a double breakthrough: to clear up the original owner's grievances, tear apart the hypocritical mask of her concubine, and slap her scumbag fiancé in the face; she also uses modern nursing knowledge to open up a new path in medicine.
She founded "An Ning Pavilion" to specialize in postpartum care and solve problems such as puerperal infection; she promoted sterile bandaging and first aid techniques, saving countless lives; she used psychological counseling to relieve the worries of the powerful.
While practicing medicine, she unexpectedly met Xiao Juezhi, the God of War of the Dajing Dynasty.
He, Xiao Juezhi, brother of the late emperor, was the North King of Fengzhen. He was stationed at the border all year round and had great military exploits. However, he was seriously injured on the battlefield in his early years and suffered from chronic diseases. His wounds were repeatedly infected and he coughed up blood at night. He had a cold and taciturn temperament and was not a womanizer. It was rumored that he was "not going to die soon and had a violent temperament."
Only Shen Ran was not afraid and took the initiative to ask for help. Later, they worked hand in hand to solve the conspiracy of the court - the internal disputes in the Ministry of Civil Affairs, the plot to seize power in the Jing'an Marquis Mansion, and the struggle for the throne among the princes; at the same time, they deeply cultivated the art of nursing, gradually promoted the modern nursing concept to the prefectures of Dajing, and established the first "nursing workshop" in the world, so that the art of nursing can benefit the people of both the government and the public.
From the abandoned daughter-in-law in a deep house in Beijing, to the most outstanding nursing hand in Dajing; from the lonely and brave god of war who is indifferent at the border, to the affectionate and dedicated infatuated prince. One person heals the world, and the other person protects the beauty with iron and blood.
