In the winter of the twelfth year of Jianyuan, Hou Bang, a scholar from a poor family, died of cold and starvation in a ruined temple. His soul witnessed the tragic scene of the fall of Ye city and the sinking of his homeland. He regretted that he had a great strategy in vain but was ostracized by the aristocratic family, hated being used as a scapegoat by the prince, and regretted that his mentor and brothers died in the battle.
When he opened his eyes again, Hou Bang returned to the afternoon when he bought half a volume of unknown military books three years ago. Memories from his past life came back to him, and he transformed from a "paper-talking" scholar into a cold-hearted counselor. He "talked loudly" in the wine shop and made secret plans: he rescued loyal and upright officials, made friends with down-and-out heroes, accurately predicted natural disasters due to rebellion, and won the reputation of "knowing things like a god" among the lower-level scholars and generals.
Langya Wang family and other clans regarded him as a threat, and the second prince Xiao Jingyan also wanted to accept him as a pawn. Hou Bang dances on the edge of a knife, paving the way for the power of all parties while guarding against being controlled. He relied on the memories of his previous life and broken military tactics, and the mysterious woman Xie Qingyi secretly helped him. When Xie Qingyi revealed his identity as the Xie family in Chen County, family interests and personal emotions made the situation more complicated.
The war in the north is rising again, and the crisis in Yecheng and the power struggle in Jiankang are coming at the same time. The princes need to accumulate strength amidst the suppression of the clan, the suspicion of the princes, and the threats of the barbarians. They must not only save Yecheng, protect their mentors, and protect the people, but also collect blood debts from the enemies of the past. With half a broken book, a lonely voice, and full of cunning, he vowed to counterattack from a humble "paper general" to become the pillar of the country, and personally rewrite the ending of blood and tears.
