(Langya Bang) the Wind Is Blowing and the Clouds Are Flying

I especially remember the old emperor's acting skills, which were very shocking

Here comes the question. Originally, the reason why Mei Changsu wanted to go to the battlefield was that the prince could not go to the battlefield. Now that the prince has gone to the battlefield himself, why does he still need to take Brother Su with him? Is it just to restore Lin Shu's identity? But as a dog-headed military advisor, he doesn't seem to be very Lin Shu. Perhaps he has forgotten that Prince Jing himself is also a very good general~

Am I the only one standing alone_(:3∠?)_
