After two days of taking this hall at the foot of the Silkworm Mountain, Ren Xiao and the others gradually figured out the situation. The entrance of the hall where they are at the moment is Tianshan Hall, and the hall master's name is Shan Lu, who is a person who is very trusted by the old ghost of the silkworm, and at the same time, this single halogen is also loyal to the old ghost of the silkworm.

That night, Ren Xiao and the five of them secretly gathered together, ready to discuss what to do next.

Luo Yun said: "After two days of investigation, I don't know if you have found out, Tianshan Hall is at the foot of the Heavenly Silkworm Mountain, but there is no enhancer here, is there something wrong!" Ren Xiao nodded and said: "I also found this point, it is indeed a bit unbelievable, it stands to reason that the main combat power of the Heavenly Silkworm Sect is these enhancers, but why can't you see any of them here!"

Mu Ziyi also expressed his opinion and said: "The purpose of our visit this time is to find out about strengthening people, but now we can't even see strengthening people, what should we do next?"

Just when a few people were at a loss, the careful Fang Liyao said: "Although we have only been here for two days, I have discovered a pattern of these people from the Heavenly Silkworm Sect, I don't know if it is useful?" Luo Yun hurriedly said: "Tell me about it!"

Fang Liyao said: "The people here will be changed every four hours, so I also deliberately paid attention to it, after every change of guard, those who have just come back seem to be very tired, and it seems that they have done a very tiring job!" After Fang Liyao said this, Mu Ziyi also reflected and said: " I really didn't notice the rotation, because these people were all dressed exactly the same, and I couldn't tell the difference, but I noticed the tiredness you said, and I began to wonder if they were on some mission, and when you said that, I remembered that it seemed that everyone was very tired!"

Luo Yun asked at this time, "Fang Liyao, then do you know where the people they rotated have gone?" Fang Liyao shook his head and said, "Because I was afraid of revealing my identity, I didn't dare to chase too deep, I only knew that they were heading towards the mountain!"

Luo Yun thought for a moment and said, "It seems that we need to find out what they are doing!" Fang Liyao, how long is it until their next change of guard?"

"About half an hour!" Fang Liyao said. Luo Yun said: "Okay, then we will divide into two ways, Lao Qiu and I will find a way to get in and see what clues we can get, Ren Xiao, you will find a way to see if you can find out anything from other people's mouths!" Ren Xiao nodded.

Time passed very quickly, this change of guard happened to be at night, and Luo Yun and Qiu Xie Ding followed the others into the team of changing guards. The changing of the guard of the Heavenly Silkworm Sect is not that a large number of people suddenly come back, and then another group of people leave, if this is the case, how could Ren Xiao not find out. Their changing of the guard is a group of five to ten people, and they rotate according to the size of the squad, and it will take at least an hour or so to complete the rotation of everyone, and it is precisely because of this that Luo Yun, who is not here, has not been able to find out.

Luo Yun and Qiu Xie Ding joined the rotation with a team, but the original five members of this team didn't know Luo Yun and Qiu Xie Ding, so they asked, "What's the matter with you two?" Luo Yun had already thought of a countermeasure, he hurriedly made a silent gesture to the person, and then motioned to a few other people to come over, and whispered: "Be quiet, haven't you noticed that there are a few people missing from our hall in the past two days?" Of course I know, two days ago, one of our team suddenly disappeared, I went to report it to the hall master, and he asked me to keep quiet, how did you know about this?"

Luo Yun didn't expect that there was this team among the people they killed before, so it would be simple, Luo Yun continued: "That's right, don't make a noise, the two of us were sent by the hall master to secretly investigate this matter, and the hall master suspects that there are undercover agents among you!" Luo Yun deliberately said a "you" in order to deter these people and make them dare not doubt themselves.

Sure enough, those few were so frightened that they hurriedly said: "I'm not an undercover agent, I'm not an undercover agent, you must check carefully, don't misunderstand good people!" Luo Yun sneered: " I am free in my heart, I don't need you to say much, but don't worry, I have already investigated you, and a few of you have been cleared of suspicion, otherwise the two of us will not reveal our identities to you, you only need to do what you are still doing now, and cover the two of us at the same time, and most importantly, we must not let others suspect us, otherwise it will be troublesome to be discovered by undercover agents!"

Those people were convinced of Luo Yun's words, and hurriedly said: "Don't worry about this, we will never let the undercover agent find out about you!"

"Alright, let's go quickly!, or it will arouse suspicion!" Luo Yun said idly, but he was ecstatic in his heart, muttering: "These people are really stupid!"

After Luo Yun and the others successfully mixed in, Ren Xiao and their side also began to act. Slightly different from Luo Yun's method, Ren Xiao saw that the seven people in a team were resting together, so he swaggered over, and then stared at the seven people intently.

Finding that someone was staring at him, these seven people looked at each other, not knowing what to do, one of them was more bold, and scolded angrily: "What are you doing? Why are you staring at us!" Ren Xiao pretended to sneer and did not speak. Mu Ziyi, who was behind him, stepped forward and slapped the man, and reprimanded: "Open your dog eyes and take a closer look, do you dare to talk back to this person in front of you?"

As soon as Mu Ziyi said this, these people instantly became empty, and another person said tremblingly: "Big ...... Adult, the little one has eyes and doesn't know Mount Tai, I don't know why you bent down here?" Ren Xiao continued to sneer and said, "Don't you know why I came here, don't you have anything to say to me?"

The man trembled with fright, and only after a long time did he say: "If you go back to the adult, the little one really doesn't know what he did wrong." ”

Mu Ziyi pretended to be angry and was about to come forward and beat this person, but Ren Xiao stopped Mu Ziyi and said to the man: "Okay, you tell me what you did today, word for word!"

The man thought for a while, and immediately said, "If you go back to your lordship, is it from the last change of guard?" Ren Xiao nodded, and the latter said: "When I changed the guard, I started to move the people in the pit out as usual when I entered the cave, and arranged him neatly in the designated position, and then there was nothing more!"

Although Ren Xiao didn't understand what he was saying at all, he still had to pretend that everything was under his control. He said, "You're right, but why did I find a few injured among the people you have carried? What's going on? Is it a few of you who broke it!" The man hurriedly explained: "My lord misunderstood, I can't make those people bad again, I already criticized me last time, this time I'm very careful, it's impossible to break them!"

Ren Xiao continued to pretend and said, "Are you sure you didn't break it?"

The man said repeatedly: "Lord Hui, it's really not me, please believe me, several of them can testify for me, this time it's really not me who broke it!" Looking at the other people nodded, Ren Xiao said: "Okay, I'll believe you once, but the problem is really among the people you carry, how do you say I should deal with this matter?"

"My lord, this is definitely someone framed me, please be aware of it, and give the villain an innocence!" the man said from the bottom of his heart. Ren Xiao continued to pretend and said: "You don't need to say this, I will naturally investigate this matter clearly, but before the investigation is clear, you can take it with me, if such a situation happens again, I will not let you go regardless of whether someone framed you or not!"

After Ren Xiao finished speaking, he left with Mu Ziyi and Fang Liyao. Although there are too many doubts that have not been solved, at the moment, they can only wait for Luo Yun and them to come back, otherwise if they continue to pretend, they will be exposed sooner or later.

"One thing is certain now, that is, the Heavenly Silkworm Sect must have a secret, and it is a big secret!" Ren Xiao said with a frown, he faintly felt that this secret was related to the safety of the entire world.

On the other side, Luo Yun and Qiu Xie Ding successfully gained the trust of the team members and followed them to a cave.

"Our task this time is relatively easy, we only need to take those modified poisonous insects to the sinkhole, I heard that the last shift is to carry people out of the pit, that is the most tiring!" said one person, and the others also chimed in: "That's right, and I heard that someone was punished severely because he accidentally injured those semi-finished products during the process of transportation!"

Luo Yun and Qiu Xie Ding couldn't understand what they were talking about, so they didn't say anything. Then they entered the cave, and like the rest of the group, they came to a room in the cave. Along the way, Luo Yun was carefully observing this cave, which was like an ant's nest, criss-crossing and very complicated, and he would get lost if he was not careful. The stone walls in the cave were very smooth, and Luo Yun couldn't guess how the cave was made for a while, because it was impossible for a person to complete such a vast and exquisite project.

Just as Luo Yun was pondering, he was taken into a room, where several rows of tables were neatly arranged, and on top of the tables were glass jars, and in the jars were all kinds of poisonous insects. Those people didn't think much about it, so they picked up the glass jar and walked out, Luo Yun was about to do the same action with them, but was stopped by these people, and said: "My lord, you are here to investigate the undercover agent, how can you do such tiring work, or leave it to us!

Luo Yun said: "You don't have to worry about me, I have my own measure in what I do!" The few people stopped talking and let Luo Yun do what he wanted.
