The letter in Lu Zhan's hand couldn't come back to his senses for a long time, he only officially started work yesterday, and if Mo Zhu hadn't sent someone to keep an eye on the person who released the carrier pigeon the next day, maybe the secret had been passed into the hands of the enemy by now.

But fortunately, the traitor did not know the role of the new weapon of the musket, and the supporting barbed wire had not yet leaked out, and a military weapon still needed advanced ideas to use.

While the French and England used tanks as auxiliary infantry at the beginning of World War II, the Hans of Germany learned to concentrate on their armored forces.

"Is there something wrong with the young master calling the slave family over in such a hurry?" Luo Yuechan walked over with a gentle lotus step, and when she saw Lu Zhan, who was pale, she knew that something was wrong.

After handing over the letter in his hand to Luo Yuechan, he explained the cause and effect of the matter in detail.

Luo Yuechan had never seen Lu Zhan's iron-blue face, it turned out to be a secret that was leaked out one night later, and now she called herself over to find out the traitor.

"What does the young master mean to find out the ghosts in the Lu family?" Luo Yuechan slowly put down the letter in her hand, looked at Lu Zhan, whose face slowed slightly, and said softly.

"What's your idea?"

"First of all, we must first check whether there will be leaks in the villa, and the villa only needs to know who is not in the villa to find out. However, according to the distance from the villa outside the city to Yanzhou City, if the spy went to the villa from Lu's house to spy on intelligence, he should have left Yanzhou City yesterday afternoon or night. ”

As Luo Yuechan expressed the speculation in her heart, Lu Zhan nodded in agreement, and Lu Zhan secretly sighed that he really didn't find the wrong person.

"Of course, until the spy is found, we need to keep it strictly secret and not let anyone know that we are investigating, so that the inner ghost can let down his guard. However, "

"You mean, what's the problem?" Lu Zhan couldn't help but wonder as Luo Yuechan wanted to speak and stopped, could it be that he wanted to expand the scope of the investigation or that he wanted to expand the scope of the investigation.

"Then please forgive the slave for being rude. This commander is deeply trusted by the young master, but the suspicion cannot be ruled out, and the suspicion of the commander cannot be ruled out until the matter is investigated. ”

Hey, Luo Yuechan's suspicion now is indeed that she didn't expect it, the instinct of the spy agency in history is to suspect all targets, although it will hurt innocent people, but this is the real spy war.

"Okay, I see, I'll pay attention to Duan Xiaohan's side. As for the investigation of the mole, I will leave it to you, this matter must be carried out secretly, and everyone can conduct the investigation without a cap, and investigate it to the end. Do you understand? ”

Luo Yuechan saluted Lu Zhan and then got up and said goodbye, sitting alone in the huge room looking extremely lonely, who would be the one who leaked secrets. With his experience of watching so many spy movies, Lu Zhan can put his suspicions on almost anyone.

Chen Zhuang, who was stationed outside the city, suddenly heard the news of Lu Zhan's arrival, and became a little scrambled, and only breathed a sigh of relief after tidying up the messy items on the table.

"Sir, are you here? You said that I was not prepared for this sudden visit. Chen Zhuang looked at Lu Zhan who came over and said.

"Do you remember when I sent a group of soldiers from you to garrison a mountain villa?"

"Remember, didn't the lord say that he was going to do the secret work of the new weapon?"

"Another batch of soldiers will be transferred over, but the security measures there are still insufficient."

Chen Zhuang called three people dressed in hundreds of households to let them strengthen the guard work of the villa, and the huge villa once again welcomed a new group of soldiers to garrison.

Lu Zhan took Duan Xiaohan to sit on the audience stage in the shooting range, watching the muskets in the hands of the soldiers spew out tongues of fire again and again.

"Xiaohan, you didn't tell anyone else about our villa, did you?" Lu Zhan pretended to ask the question casually.

Lu Zhan didn't want to believe that Duan Xiaohan had leaked the information intentionally or unintentionally, so he planned to give Duan Xiaohan a try. Comprehensive judging is made by observing changes in facial expressions and tone of voice.

"No, Lin Jie asked me where I went yesterday, but I didn't reveal any information at all."

Looking at Duan Xiaohan's sincere eyes, Lu Zhan believed Duan Xiaohan's testimony, since it was not Duan Xiaohan who leaked it, then who could know about the place of the villa.

This mountain villa was given to him by the family of Yanzhou, could it be that there was something wrong with them? This is really a problem, although I have watched countless spy movies, it is really a big problem when I want to actually operate it.

Now I can only hope that Luo Yuechan will find out the inner ghost.

Lin Jie, who was in the Lu family, suddenly had a very bad premonition, and she felt as if someone was eyeing her.

Luo Yuechan successively sorted out the alibi of all the Lu family at the time of the incident, and most of the subordinates lived in collective dormitories, so the alibi of those subordinates were all valid.

Now only those who have an independent yard are suspicious, but those who can afford to live in an independent yard in the Lu family are not ordinary people.

"This is really nerve-wracking, those who have independent yards are not so easy to check." Luo Yuechan pointed her finger at her head and rubbed it gently.

However, since the young master has given himself the power to check to the end and add no cap, even if it is a big man, he must check it. After all, at the beginning, Lu Zhan instructed that counter-espionage work was originally a matter of offending people, because many people were suspicious.

Luo Yuechan circled the people from the capital on the paper, and Mrs. and Xiao Yezi were all suspects. It is impossible for Madame to betray the young master, and at the same time, Madame does not know where Lu Zhan has gone. Such a good wife and mother-like character may be too low.

Xiao Yezi has always been Lu Zhan's personal maid, and naturally she has nothing to say in terms of loyalty, but with her own understanding of her, she is a simple person, and such a person is easy to be tricked.

Luo Yuechan smiled slightly and decided to investigate Xiao Yezi first to see if she had inadvertently revealed the secret.

"Miss Luo, what are you calling me to do today?" Xiao Yezi took the cup of hot tea handed over by Luo Yuechan, and looked at Luo Yuechan who suddenly invited her over today with wide eyes.

"It's nothing, I just want to find out if anyone has asked you about the villa outside the city recently."

Xiao Yezi originally wanted to say that Lin Jie asked herself yesterday, but after thinking about it, Luo Yuechan, who felt that it was a bit unrighteous to say that matter, so she flatly denied it.

After seeing the appearance of wanting to speak and stopping but suddenly denying it, I already had a conclusion in my heart. This little leaf must have something to hide from himself.

It seems that the key to solving the secret theft case of the musket lies in Xiao Yezi.
