On the day he was demoted to the frontier army, Shen Jin knelt at the camp gate with the enemy commander's head, exchanged blood for power, and regained control of the remaining army. Qin Zhao watched with cold eyes, but quietly held down the bowstring when he attacked the enemy camp at night. Iron bones hide secret orders, white crane feathers breed poisonous weeds, Pei Zhongheng secretly cuts off grain routes, and Tuoba Lie smiles at the wind and clouds. The wind and snow at the border are not hiding the smoke, can one person and one sword cut through the thousands of connections in the court? With military power in hand, he wants more than just survival - he wants to overthrow the foundation of this cannibal dynasty.
Shen Jin used the enemy commander's head to regain military power, but was secretly warned by Qin Zhao: There were traitors in the border army. Tiegu handed over the secret order, revealing that Pei Zhongheng had colluded with the barbarians and was deprived of food for three years. Shen Jin used Bai Heling's 'Soul-Breaking Grass' to set up a poisonous array, destroying three enemy camps in one night, which shocked the northern border. However, the truth about the death of Qin Zhao's old subordinate came to light, and it was actually related to the death of her father, the general and the prince in the court. Tuoba Lie took advantage of the situation and presented a "fake letter of surrender" to induce the court to send troops for reinforcements - in fact, he was trying to lure the tiger away from the mountain and intend to annex the nine towns. Shen Jin saw through it but took advantage of it, pretending to be captured, and sent the evidence of Pei Zhongheng's crime to the imperial court with the help of Tuoba Lie. There was a shock in the court, the prince was imprisoned, and before Pei Zhongheng committed suicide, he revealed that Qin Zhao was an orphan from the previous dynasty. Bai Heling reveals her life experience: She is a descendant of the witch god whose family was wiped out, and the soul-breaking grass is the holy medicine that Qin Zhao's biological mother gave her life for. Shen Jin led the remnants of his troops to go north to recapture the occupied Tianlang Pass, but Tuoba Lie's real goal was to open the underground imperial tomb and reestablish the former dynasty. The frontier army is no longer a place of exile, but the eye of the storm for dynasty change.
