In "Bright Sword", how did Li Yunlong discover that Zhu Ziming was a traitor?

Among these anti-Japanese war-themed film and television dramas, the most popular and authentic one is "Bright Sword", which truly explains the hardships of the anti-Japanese war. From this drama, we learned a lot of common sense in life. , for example, there is a section in the play where Li Yunlong touched Zhu Ziming's quilt during his rounds and concluded that he had rebelled. So why is this?

I believe everyone is familiar with the drama Liangjian. There was a character in this drama. This person was very special. He was Zhu Ziming, who was responsible for the security work. Without this person, Li Yunlong would not have been able to successfully siege Ping'an City. This person is not a positive character, Li Yunlong just used him, because he rebelled, which made the audience hate him

Just when Yamamoto was about to take action, Li Yunlong suddenly inspected the sentry post and discovered that After Zhu Ziming left the barracks, he immediately took out his pistol and asked everyone to prepare for battle. This detail is a bit confusing. Zhu Ziming was not in the barracks, so why could he be discovered and make such a judgment? With this move, Li Yunlong must have found out through some clue that something was wrong with him.

The reason why Li Yunlong had such doubts was mainly because he had long discovered that there was something wrong with Zhu Ziming. After all, Zhu Ziming was originally a person with an explosive personality, but later his personality became more and more... He was docile and his temperament had changed a lot, so Li Yunlong concluded that Zhu Ziming must have done something that he didn't want to attract everyone's attention.

On the day of Li Yunlong's wedding, Zhu Ziming's bed was cold. From this point, it can be seen that Zhu Ziming has been away for a long time. This is a very clue for Li Yunlong, who is thoughtful, and also It was determined that Zhu Ziming wanted to collude with the enemy to launch an attack on this special day when everyone was unprepared.

After touching Zhu Ziming's quilt, Li Yunlong quickly ordered action and successfully broke through. Li Yunlong is loved by everyone in "Bright Sword". Although he is a hot-tempered person, he is very capable of guiding and convinces everyone. He has led the army to win many battles.
