With the click of the door, the hearts of several people jumped violently, and the old crane pushed the door, a very ordinary-looking backyard, and after looking around, he found a manhole cover.

"Here, this is it. Xuan Lin glanced at the notebook and pointed to the manhole cover.

Fish rush in.

"It's about the same as the underpass we went down near the car wash. The old hanging touched the wall, a little surprised and a little disappointed. The surrounding buildings are indeed not much different from the scene where he and Yan Jiucheng went down near the car wash.

It's still an ordinary mud wall, about two meters high and one meter wide space, and there are some sensor lights along the way, and the lights look tattered. This is different from what Lao Hang imagined, what about the technology that was said to be 20 years in advance?

At least these putties have to be scraped well, right?

None of them spoke, and after walking quickly and quietly through the underpass for a while, there was a fork in front of them, and the two ends of the fork looked much brighter.

"Show me the map. Gu Miqing, who was walking in the front, stopped and glanced back at Xuan Lin.

Although the underground passage of the villa area was not monitored according to itself, the battle between Yan Jiucheng and Lao Hang in the car wash room was very beautiful, and he touched part of the route of the underground passage, and these routes were the routes of the new scientists guarding the villa area.

The current situation is that from the outside to the inside, there are three guard rings, and the further inside, the more heavily guarded. The last guard ring is concentrated under a villa in the northeast corner, so it is common sense to infer that this villa in the northeast corner is most likely the villa of the scientist to be rescued.

"You don't have to look at the map, go this way, there are guards over there. Yan Jiucheng stretched out his finger and pointed to the right, the map was remembered in his head, and he walked out first, followed by the other three.

This underground passage is obviously different from the previous ones, the sensor lights are much brighter, the passage is much more spacious, and most importantly, you can see the surveillance on the wall in the distance.

"No problem, I'm shielded, let's go. Xuanlin's notebook was always open, and he held it in his hand, and he couldn't walk quickly, so he fell to the back.

"Be careful, everyone. Gu Miqing walked a few steps quickly, followed behind Yan Jiucheng, the muzzle of the gun in her hand was always facing the front, and she walked sideways, staring at the front and looking at the back. In such a long and narrow space, once you encounter someone who has nowhere to hide, it is destined to be a bloody battle. And the bloody battle will definitely make a movement, and if it makes a movement, it will definitely attract other people to come.

In short, every step is terrifying.

"I hope you don't meet someone, if you meet someone, Lao Hang, you are in charge of the back, I am in charge of the front, by the way, Xuanlin, you ......" Gu Miqing lowered his voice to deploy, but saw Yan Jiucheng suddenly stop.

Gu Miqing raised the gun suddenly, and quickly stepped in front of Yan Jiucheng, his gaze was full of murderous aura.

"You're at the front, and you look big. Yan Jiucheng raised his hand, turned his wrist, let the watch point at him, and then said, "Come closer, take a selfie." ”

……

Gu Miqing thought that there was something wrong with his ears and heard it wrong.

Selfie?!

Her muzzle was still pointed forward, and her body was still instinctively blocking Yan Jiucheng's approach, seeing his raised hand and watch, the mode of the watch was adjusted to the shooting picture.

Is it really a selfie?!

"When's it, you...... Gu Miqing was instantly furious, turned his head and glared at Yan Jiucheng viciously, this is, Yan Jiucheng pressed the shutter button.

"Tsk, you didn't shoot this well, and you look too fierce from the side. And Xuanlin, you have to come up, everyone lean closer, put the sunglasses on the top of your head and don't block your face. Yan Jiucheng said as he stretched out his hand and pinched Gu Miqing's face directly, and straightened her up.

Although the shutter button of the watch only needs Yan Jiucheng to look at the upper right corner and blink, and there is no click, but Lao Hang dubbed it.

"Click. He laughed.

Subsequently, Yan Jiucheng and Xuan Lin also laughed when they heard Lao Hang's dubbing, and the only one who didn't laugh was Gu Miqing, who was pinched by Yan Jiucheng. She pushed Yan Jiucheng away, pointed the muzzle of the gun at him, and said very seriously: "Now you are doing business, it is very dangerous, you still have the leisure to take a selfie?!"

"It's because it's so dangerous that I want to take a picture. Yan Jiucheng pointed at Lao Hang with a hippie smile: "Look, a few of us are wearing sunglasses, how handsome, we have to stay at such a handsome moment, and we will have a thought in the future." ”

As he spoke, he pressed it on his watch, and the image was sent to everyone's watch.

"We have to take a picture, we're so handsome. Lao Hang agrees with Yan Jiucheng's words, he has been wandering in the rivers and lakes for many years, and he understands that there are not many handsome moments in life, and the task has been carried out until now, several people are wearing black clothes and black sunglasses, such a sassy moment has to be filmed.

Besides, Gu Miqing is also right, at such a dangerous moment, if you don't get it right in the next second, someone will be finished with the calf, and you have to take a picture.

"Hmm? Why did I close my eyes. Xuan Lin glanced at it and smiled a little depressedly. The footsteps of several people were very fast, and no one looked at the photo carefully, and when Xuan Lin said this, several people looked at it.

I saw that in the dim passage, Gu Miqing frowned and looked fierce, but unfortunately his round face was pinched and bulging by Yan Jiucheng, which made the fierceness funny and cute. Yan Jiucheng behind her had a wicked smile on his face, very proud; Lao Jiao's thick eyebrows and big eyes were very eye-catching, and he looked like a big brother at first glance, and Xuan Lin, who had always only maintained a polite smile, grinned rarely, but unfortunately closed his eyes.

"There is a chance to take a picture of someone wearing sunglasses, damn it, how can there be eye shit in the corners of Lao Tzu's eyes?" Lao Hang took a closer look at it, and expressed dissatisfaction with his photo. The most dissatisfied is Gu Miqing, she is at the front, obviously her face is the smallest, but she is the biggest.

"Doing business, still thinking about taking a selfie!" Gu Miqing was arrogant, naturally embarrassed to say that he didn't shoot beautifully, so he could only criticize Yan Jiucheng in a low voice.

"When I'm old, I'll show this picture to my grandson. Speaking of this, Lao Hang suddenly stopped: "No, we have to keep it secret, let's have a pair wearing sunglasses in a while, so I can show off." ”

"We'll have to survive. Xuan Lin said quietly.

For a moment, the four of them were silent, and only the sound of faint dense footsteps remained in the underground passage. The four of them all knew in their hearts that it was difficult to say whether they could get together the four of them for the next photoshoot. This is probably the last photo they will take together.

"Let's shoot one, now. Yan Jiucheng stopped again.

This time, Gu Miqing did not object, but silently took off the sunglasses and put them on his face, the four of them leaned closely, and were about to take pictures, when they suddenly heard a very rhythmic footsteps.

This footstep made the four of them immediately enter a state of readiness, and in an instant, Gu Miqing raised his gun and aimed it at the front, Lao Hang's muzzle was aimed at the back, and Yan Jiucheng and Xuan Lin were in the middle.

Yan Jiucheng quickly took out the * and quickly called up the map from his head. "Don't be nervous, according to the route, they are changing shifts and will not go through our passage. The speed of retrieving the memory made his head shake.

Sure enough, the footsteps faded away.

"The problem now is that no matter which way we go, there are people at those levels. Xuan Lin glanced at his notebook, uneasy. He was right, although Yan Jiucheng did not master all the routes of the passages, judging from the current mastery, it is obvious that the underground passage routes in this villa area are very similar to spider webs. Wherever you go, you'll have to go through those levels.

It's just that the farther you are on the periphery, the farther apart the levels are, like the periphery of a spider's web. The further you go in, the more dense the levels become.

It has not yet been found where the scientists live, and in such a situation, the operation must be secretive, that is, it cannot be discovered.

"It's impossible not to be discovered, if it's far away, it's okay, the more you go inside, the closer the levels are, it's impossible. Xuan Lin stretched out his hand and drew a circle on the map. I saw that the circle around the villa in the northeast corner had four checkpoints, each less than fifty meters.

Xuan Lin said, while sitting on the ground and pointing to the map, I saw a few black dots on the map on the road they passed: "These black dots are where we passed by, I temporarily blocked the surveillance, but the monitoring of their underground passage is difficult to sneak into, I can only destroy, I can't view it in a short time, unless I find their base station, I can sneak in to view their surveillance." ”

"The base station, that must be in the center of the place. Yan Jiucheng frowned.

Xuan Lin nodded.

If Xuanlin's monitoring eye can't work for the time being, the difficulties it faces are more than a few people imagined. You must know that the information you have before tells Yan Jiucheng that this defense is all people from major organizations, and the more you go inside, the better the people are.

These are nothing, the most important thing is that the further in, the more levels, to be silent, it is completely impossible. After all, even if you kill the guards quietly, the patrol is not blind, and when you find someone dead, your whereabouts are exposed.

"One step at a time, and now we're still on the periphery, and the level is far away. Yan Jiucheng gritted his teeth and pointed to the front: "There is a checkpoint around the corner, let's enter it first in a while." ”

"What do you call it?" Gu Miqing, who has never fought unprepared battles, immediately objected: "If we go in and have no way to get out, it will be a failure." If there is no suitable way now, I recommend withdrawing first. ”

"Yes, get out, or look for the base station on the periphery, as long as I find the base station, I can sneak in here to monitor. Infiltrating the surveillance and finding their position is half the battle. "Xuan Lin is also a conservative, although he now recognizes Yan Jiucheng's ability, but he does not recognize his way of doing things. Because Yan Jiucheng is too casual.

What does it mean to take one step at a time? These don't sound like words that a captain should say.

"Am I the captain or are you the captain?" Yan Jiucheng, who was always in a hurry, became serious at this time, he glared at Gu Miqing, and then at Xuanlin.

"Yes...... Gu Miqing still wanted to say something.

"But what?" Yan Jiucheng interrupted Gu Miqing's words with a cold face, and made her look cold.

Gu Miqing pouted and didn't speak again, but thought in his heart, good guy, this guy is weird and terrifying.

"Withdraw now?Do we have a more suitable time to infiltrate than now?!" Yan Jiucheng no longer looked at Gu Miqing or Xuanlin, but then took out the potion from his pocket and began to order directly: "In a while, the people at the checkpoint will be stunned first, and we will enter the second circle." Xuanlin, you immediately contact the organization and inform the scientists of our specific location of the shadows around you. ”

"Start the shadows?!"

"Yes, it's time to activate the shadows. ”

The shadow son was told by the old man when they came here, there is a shadow son that has been lurking for two years by the scientist's side, helping at critical moments, and sometimes the ability to take the storm.

It's not easy to raise a shadow. Especially the shadows around these two scientists, it is even more difficult. You must know that the national defense of country M has already been distilled, and the two of them have returned to the big eastern country and have been investigating the people around them for a long time. The shadow son who can be raised by these two people until now is extremely precious. And what is even more precious is that this shadow followed to the villa area.

This is equivalent to having a pair of eyes near the scientist, which is your own person.

Being able to live until now and not being found to be a shadow child shows that this person's thinking is rigorous, intelligent, and extraordinary, and extremely precious.

"It's not easy to meet someone who is suitable for shadowing, which is less than the probability of meeting a genius. Therefore, the shadow cannot be easily activated, once it is activated, it means that it is easy to be exposed, and once it is exposed, it means death. ”
