The night before the army's departure, Chen Yan quietly came to the back mountain forest to report the news, so that the Jinghe army could make early preparations. The next day, General Cao led all the soldiers to go to Xifeng Fort. The march was very smooth, and even Xifeng Fort was not armed, which made him very puzzled. Chen Yan lobbied General Cao not to worry too much. Now that the arrow is on the line, he will order the attack of the fort no matter what.
Sure enough, layers of traps were laid in West Wind Fort, and the cavalry charge was ambushed for this reason, and it was difficult to escape. Now that the situation is critical, Sima Jin ignored the military orders, and immediately released Sima Wangyue, ordering him to take the rest of the soldiers and horses to help the West Route Army break out of the siege. Sima Wangyue was ordered in the face of danger, promising that he would not let go of his trust, and then joined hands with Chen Yan and Mu Nan to repel the enemy's attack, and finally won the respect of his colleagues.
Also because of Chen Yan's contribution to saving Wei Cangjun from the fire and water, Sima Wangyue remembered this kindness. Chen Yan half-jokingly expressed that he wanted Sima Wangyue to agree with him, but Sima Wangyue readily agreed after hearing this, without any shyness. In contrast to the failure of this battle, General Qi suspected that General Cao had rebelled, and revealed to Sima Jin that General Cao knew about Sima Wangyue's daughter.
Although General Cao has a violent temper and speaks outspokenly, Sima Jin, remembering that General Cao has been loyal to the emperor and protecting the country for many years, really does not believe that he will collude with the enemy and treason. There is no evidence at present to jump to conclusions. That night, Chen Yan dreamed that his identity as a spy was exposed, he faced the Sima family facelessly, and even witnessed Sima Wangyue jumping to his death from the city wall, and he woke up from the nightmare instantly.
Chen Yan was injured and it was difficult for him to walk. Sima Wangyue brought him to the forest to have a heart-to-heart talk, and the atmosphere between them was particularly ambiguous. The beauty of this moment made Chen Yan a little depressed, and he began to think about why there was a war. If the two countries stopped fighting, there might be a future between him and Sima Wangyue, and how could so many innocent people be hurt.
Sima Jin pondered over General Qi's words over and over again, and he really didn't have enough confidence to prove General Cao's loyalty, so he hurriedly called Mu Nan back to the city in private, and asked about the reason for his conflict with Wang Yue's identity. Mu Nan truthfully stated that these people were all veterans stationed in the isolated city, and most of them were General Cao's subordinates. This shows that the exposure of Sima Wangyue's daughter may have something to do with General Cao.
While they were talking, news came from the palace that the emperor pardoned Sima Wangyue's crime of disguised as a man to join the army. Sima Jin was overjoyed and immediately decided to hold a banquet, firstly to celebrate, and secondly to clarify in person. General Cao received an invitation letter written by Sima Jin himself, and specially ordered a jar of good wine from the winery. Unexpectedly, Yin Keji had already poisoned the wine.
At the banquet, Sima Jin took the initiative to ask why the soldiers chose to join the army. Although everyone answered differently, they all had the same belief, that is to repel the enemy and defend the country. The vigor of the generals is deeply rooted in the hearts of the people. Sima Jin hopes that after this battle, no matter how high or low their status is, they will live in harmony and treat each other with sincerity, and never intrigue.
Sure enough, as soon as the words fell, General Cao immediately stood up and apologized to Sima Jin, admitting that he deliberately spread the news about Sima Wangyue's daughter because he was jealous of Sima Wangyue. Fortunately, Sima Wangyue did not pursue the matter, and he and General Cao settled their suspicions. General Cao took out the good wine he had ordered to toast them. Mu Nan thought that Sima Wangyue was blocking the wine and drank a glass, but he vomited blood on the spot.
Seeing this, Sima Jin was furious and ordered General Cao to be imprisoned. The military doctor gave Mu Nan a detailed diagnosis and treatment, but he was still at a loss what to do, because the poison Mu Nan was suffering from was a strange poison familiar to Jinghe warlocks, without the antidote for this poison, he would undoubtedly die. Then Sima recently interrogated General Cao in prison and forced him to confess the truth. General Cao thought he had a clear conscience, and Sima Jin tortured him because of his arrogance.
On the other side, Mu Nan's symptoms of poisoning became more and more obvious, and even wrapped in a thick quilt, he still felt bitingly cold. Mu Nan knew that his time was short, so he wanted to express his heart before he died, saying that he would have no regrets in dying with his beloved by his side in this life. Sima Wangyue finally understood Mu Nan's thoughts, but she couldn't respond directly. Instead, she ran to the prison and beat General Cao angrily, ordering him to hand over the antidote, but she got nothing.
