In the Bingwu Year of the Horse, the war at the border is rising again. Sixteen-year-old girl Li Zhao put on her father's worn armor, cut her long hair on New Year's Eve, and stepped into the cannibal military camp in place of her seriously ill father.
From the mud of the new barracks to the blood and fire of the vanguard camp, from the moonlit night of secretly learning the art of war to the game with the general in front of the sand table. She learned to be ruthless among the dead, and learned the tricks in the military formation. When the pear blossom spear defeated the enemy general, no one knew that beneath the iron face was a girl's face.
One year and three months, from soldier to captain. In two years and seven months, he went from a partial general to an "iron-faced general" guarding one side. She fulfilled her promise to her father and shone brightly, but in the whirlpool of power and blood, her original appearance gradually became blurred.
When a bigger conspiracy swept across the court and the border, when the general who admired her in the past suddenly became the most dangerous enemy, when her true identity was about to be exposed - Li Zhao finally understood that the most difficult thing on this road was not to kill the enemy, but to keep the original heart in the mountain of corpses and sea of blood.
"I am not a natural general, but I am a natural warrior."
