As soon as this was said, Ma Huibing didn't know what to say. Someone familiar with the trap? Apart from the people from the R organization, where else can there be such a person?

"Besides the people from the R organization, who else can be familiar with the traps there?" Ma Huibing said it directly.

"Isn't it just the people from the R organization?" Zhao Yulin said another sentence.

Zhao Yulin had already said this, and Ma Huibing finally understood, "People from the R organization? You want to use the people from the R organization to find out what their underground base is like?"

No matter what, Zhao Yulin's idea is a bit unrealistic, right? At this time, he still expects that member of the R organization to turn over a new leaf and help him? Don't even think about it!

Just when Ma Huibing was about to say something, Zhao Yulin took out some pinhole cameras from his backpack and said, "You brought so many with you, so you might need them. We'll rely on them this time."

"You want to install the pinhole cameras on them?" Ma Huibing finally understood what Zhao Yulin was thinking.

Zhao Yulin nodded, "I just don't know if there is a chance to run into them. If it succeeds, it will be twice the result with half the effort."

It is undeniable that this is indeed a good plan, but Ma Huibing is still a little worried, "What if they have some metal detector there? In that case it will still be discovered, right?"

Zhao Yulin nodded, "You are right, so we need to do some experiments to verify whether your idea is right."

However, Zhao Yulin's strange way of answering made Ma Huibing feel at a loss. He had no idea what Zhao Yulin was trying to do now. His thoughts were as unpredictable as his strength.

"Do an experiment? How do we do it?" Ma Huibing really didn't want to hear Zhao Yulin's suspense. He hoped that Zhao Yulin could tell him his plan in detail.

"First, we need to find a suitable member of the R organization and put this on him to try it out." Zhao Yulin took out a small cube from another part of his backpack.

"What is this?" Ma Huibing thought that Zhao Yulin had taken out something strange again, so he asked immediately.

"The material inside is the same as the pinhole camera. Put this on the member of the R organization. If he is not discovered in the underground base, then the camera installed on them will not be discovered." Zhao Yulin said slowly.

Hearing what Zhao Yulin said, Ma Huibing understood immediately, "Haha, good idea, this experiment seems worth doing."

"Even if the other party finds this thing, they can't find anything. Don't worry, we just need to keep observing the entrance to the underground base." Zhao Yulin said slowly.

After finishing this sentence, Zak came out of the room, "I have made the bed, you can sleep in the room tonight."

Zhao Yulin stood up, "Mr. Zak, before that, I have another question to ask you."

"Okay, ask as much as you want, and I will answer if I know." Zak said quickly.

"Then I'll be frank, do you know how many entrances there are to the underground base of the R organization?" Zhao Yulin asked.

Zach thought for a moment, "As far as I know, there are three places. One is in the middle of the holy city, which is the largest entrance, and the other two are on the border."

Zhao Yulin nodded, "It's simple. These pinhole cameras don't have to be used on a certain person. They can be installed near the entrance to monitor their every move."

However, Ma Huibing still had some concerns, "Isn't this safe enough? At least we have to make sure that this thing is on him. "

Zhao Yulin took out a small machine from his backpack again," This is a metal detector. This thing contains special metal materials. The metal detector can detect the wavelength of the electrons inside. As long as the signal receivers are spread throughout the holy city, he can receive the signal no matter where he goes. "

What Zhao Yulin said seemed a bit mysterious. Ma Huibing didn't know if it was really that powerful, but now it seemed better to believe Zhao Yulin.

"This is not a problem. Zak and I will go together to pack these things up." Ma Huibing said directly.

Zak also nodded quickly. After all, if everything went well, maybe all the guys from the R organization could be driven out! He would definitely help with this kind of thing!

"Okay, I'll leave this matter to you. I'll go out for a walk and take a look at the situation nearby." Zhao Yulin said slowly.

However, this sentence made Ma Huibing feel something was wrong, "Hey, you're still going out? Aren't you afraid that the guys from the R organization will recognize you?"

Zhao Yulin smiled, and then took out a hat and white cloth from his backpack, "Arabs like to cover their heads with these, right?"

It seems to be true, because when rushing into the holy city just now, Ma Huibing also noticed that most of the locals had their heads covered with scarves.

At this time, Zhao Yulin continued, "I know what I am doing. Just leave this matter to me."

As soon as he said it, everyone started to act. After all, Zhao Yulin and Ma Huibing didn't intend to stay here for too long. After collecting the necessary intelligence, they would leave here immediately.

Now Zhao Yulin was walking on the street outside. Most of his face was covered by a white cloth, leaving only his two eyes exposed. In this way, I'm afraid not many people could recognize Zhao Yulin.

Zhao Yulin walked around, and soon he saw two members of the R organization patrolling on the street in front of him.

The two guys didn't look like high-ranking members of the R organization. Zhao Yulin didn't stop or walk back, but pretended nothing happened and walked forward. He didn't want to arouse the suspicion of those members of the R organization.

This street was quite busy. In addition to Zhao Yulin and the two members of the R organization, there were many people walking on this street, so the two members of the R organization didn't notice Zhao Yulin at all, but just walked forward.

After they passed by, Zhao Yulin stopped, turned around quickly and followed.

Zhao Yulin came to the street to find the right members of the R organization and throw the piece of metal into their pockets to conduct the experiment mentioned earlier. Now these two people seem to be just minions, so they are the best subjects for the experiment.

However, Zhao Yulin is just following them at a very slow speed and has no intention of taking direct action. Zhao Yulin is not sure if there are any of their accomplices nearby, so he still wants to see the situation first.

The two people did not find that Zhao Yulin was following them. After walking for several hundred meters, the two members of the R organization came to a forest.

Zhao Yulin had already surveyed the terrain before entering the Holy City, so he knew there was a small forest here. However, now his detection range only includes these two members of the R organization, so he did not think he was in danger.

And most importantly, in such a sparsely populated place, it was a good opportunity for Zhao Yulin to fish in troubled waters. He took out the piece of metal from his pocket, controlled his footsteps to the minimum, and with the help of the graceful and amazing, he quickly put the piece of metal into the pocket of one of the members of the R organization.

As they walked, the member of the R organization whose pocket Zhao Yulin put the metal in felt something was wrong, as if something had just appeared behind him, so he immediately stopped and turned around to see if there was anything wrong behind him.

However, there was no one behind him, and there was nothing wrong at all. Another member of the R organization noticed that he suddenly stopped and immediately asked, "Hey, what are you looking at?"

"Strange, I just felt like there was something behind me." The guy said slowly.

"What is it? Did you not sleep well last night? Is there anyone behind me?" Another member of the R organization did not see anyone behind him, so he said so.

The guy scratched his head and said, "Maybe he is overly sensitive. Let's go."

After saying that, the two continued to walk forward. After they walked nearly ten meters, Zhao Yulin slowly walked out from the bushes beside him.

I have to say it was quite thrilling just now. Fortunately, Zhao Yulin hid in the bushes quickly and did not make too much noise, otherwise they would definitely find him.

Zhao Yulin gently patted the grass and dirt on his clothes. Now that his goal has been achieved, there is no need to stay here. He will go back to Zak's house first.

However, at this moment, Zhao Yulin felt that someone had entered his detection range!

There was only one person coming, and he was slowly approaching here, but his movement speed was very slow, and it didn't feel like he was walking normally, which was very strange.

But Zhao Yulin didn't plan to pay too much attention to it. After all, the person was not coming towards him, but towards the path between him and the two members of the R organization. So Zhao Yulin didn't want to cause any more trouble and thought about going back quickly.

However, the moment Zhao Yulin turned around, he heard a woman's moaning from behind!

There was no doubt that the sound came from the person who had just entered Zhao Yulin's detection range. Although the sound was very small, Zhao Yulin could still judge that it was a female voice, and somehow, Zhao Yulin felt that the voice was familiar, as if he had heard it somewhere before.

Originally, Zhao Yulin didn't want to get involved in this matter, but at this time he found that the two members of the R organization also stopped, and they seemed to have heard some commotion nearby.

"Hey, this is not an illusion, right? There is really a sound, should we go and take a look?" said the member of the R organization to whom Zhao Yulin put the metal.

At this time, Zhao Yulin hid in the grass nearby again, intending to take a good look at what will happen next before deciding what to do next.
