In "Langya Bang", with the development of the plot, more and more people gradually discovered Mei Changsu's true identity, including Emperor Liang, who was also suspicious, suspecting that he was Lin Shu, the young marshal of the Red Flame Army thirteen years ago. So, does Yan Hou know this truth? Or in the finale of the plot, is he still only suspicious and not sure that Mei Changsu is Lin Shu?
From the doubts at first sight to the final conviction, Yan Hou has undergone a complex and subtle psychological transformation. Every time he confronts or cooperates with Mei Changsu, he inadvertently collects clues about the true identity behind this mysterious figure. Although every sign pointed to Lin Shu, there was always some uncertainty that made Yan Hou unable to make up his mind.
Mei Changsu speculated Yanhou's plan according to the citrus brought by Yujin, and took the initiative to come to the door, exposing his plan to "blow up" Emperor Liang, knowing that Yanhou was discouraged and disappointed by Emperor Liang's current approach, for the "cinnabar mole" and his former brother in his heart, he was not ready to endure anymore, but to avenge it, Mei Changsu reminded Yan Hou that Emperor Liang's death would not correct the names of the people who died due to the unjust case of the Red Flame Army at that time, they still have a stigma, the world still does not know what happened at that time, and the Hanging Mirror Division will investigate thoroughly, At that time, Yujin was implicated in the funeral for this reason, and persuaded him to stop for the sake of Yujin. At that time, Yan Hou was already suspicious.
When Mei Changsu made trouble in the Marquis of Ningguo's mansion. Mei Changsu arranged Gong Yu, and used the matter of Nian Nian's two brothers and sisters to "recognize their relatives", and made the "life secret" hidden in the Marquis of Ningguo's mansion public to the world. Xie Yu hated him to the core, and was ready to go on a killing spree in the mansion and kill everyone who knew the truth. At this time, Yujin was trapped in it, and Yan Houdi rushed to save people. When he saw King Yu leading the government army, Yan Hou naturally knew everything that happened in Ning Guohou's mansion, and Mei Changsu was indispensable behind the scenes. At this time, Yan Hou had already begun to doubt what Mei Changsu's true purpose was.
Xia Jiang pointed out in front of Emperor Liang that Mei Changsu was Lin Shu whose face had changed after being poisoned by the cold, and in the process of confrontation, although the only people present at that time were Emperor Liang, King Jing, Xia Jiang, and Gao Gonggong, but there was no impermeable wall, how could it not reach the ears of those who had a heart. Yan Hou really doesn't know?
Mei Changsu and King Jing were ready to persuade Yanhou and the eldest princess to help them in the final "palace forcing link" against Emperor Liang, with the purpose of avenging the 70,000 Chiyan souls and asking Emperor Liang to retry the Chiyan case. If Yan Hou hadn't guessed that Mei Changsu was Lin Shu at this time, it would be impossible.
In the end, the Northern Yan attacked, and Mei Changsu decided to return to the northern battlefield and continue the mission thirteen years ago. When he rode majestically in armor and looked extraordinary among the many soldiers, the general no longer needed any verbal confirmation at this moment, because all the signs, all the actions, all the temperament converged at this moment into a clear and irrefutable conclusion: the hero in front of him who was ready to sacrifice his life for his country was none other than Lin Shu.
