Yelena walked slowly through the passage. Lin Rui couldn't see the face behind her helmet, but he didn't need to look at it to recognize her as Yelena...... Not to mention her scoped sniper rifle, of course.

She looked around cautiously, and after confirming that this place was safe, she put on her sniper rifle and followed Lin Rui. "So you got there before me, and I thought you were dead in the snow outside. ”

Lin Rui said helplessly: "From your cheerful tone, I know that you don't think so." If I die, you'll be a little sad. ”

"You're so confident. Yelena smiled.

"Alright. Now let's confirm the goal. Lin Rui called up the topographic map on his tactical tablet, "Mission 1: We have to rescue those captured hostages." Mission 2: If there are no survivors left, we must clear the area of enemy forces. At the same time, we should try to avoid contact with enemy forces. ”

Yelena nodded.

Lin Rui marked four roads leading to the ground facilities with high brightness, making them the most conspicuous things on the electronic map.

"First of all, we have to avoid these routes. These passages are too conspicuous, and those mercenaries are all experts, and they will definitely patrol these places. He drew a circle in another place on the map, "We're going to avoid this place too." According to the information provided by the Russians, this is the control room. Now it may be the headquarters of those mercenaries, and if nothing else, there will be a large number of enemy troops. Even if we force our way in, we will miss the opportunity to rescue us. ”

"And how do we get in?" said Yelena, frowning.

"Let's go this way, along the maintenance line. Don't go beyond that. Also be careful not to leave any available cover. The maintenance passage is very hidden, and there are many accessory rooms, maintenance wells, and complex passages. They don't think that we are going along this route. Lin Rui drew a line in a very dense pipeline diagram.

"It's 18 o'clock. The center of the city is almost five kilometers away - we can reach it in less than an hour. We may be forced to slow down in order to evade enemy patrols - but we must not get there later than an hour and a half. Lin Rui said.

Yelena zooms in on an electronic map. "This is the entrance to the waterway system in ......"

"Yes. Lin Rui marked it on the map with a marker. "Here, here, and here. We can access the central area through these points. Questions?"

"But our communication system is limited locally. Yelena frowned and said, "If we keep walking, how do we keep in touch?"

"We don't need to be in touch because we're going to act together. Lin Rui put away the electronic map, "In the case of too few people, it is more certain that we will act together." This is our only chance. ”

"Understood. She said.

"Be vigilant. Lin Rui smiled slightly, "It's still the same old saying, I hope we can come back alive." ”

They checked their equipment again: modified AK-12 assault rifles with silencers, eight spare magazines, demolitionist grenades, and combat daggers. There is also the Giurzaban Viper pistol - a small but powerful pistol. In addition to these weapons, there was also a pack of C4 explosives carried by Lin Rui.

"Let's go. He said.

Lin Rui and the two began to act. They quickly entered the underground passage, Lin Rui walked in the front, and Yelena followed him. The two of them were not in a straight line, Lin Rui was slightly to Yelena's left. In order to ensure that in the event of an accident, both of them have a good view of fire.

The two men moved forward cautiously. Every hundred yards he walked, Lin Rui would signal to stop, and then he would search the surrounding area to confirm that there were no enemy troops. At this point, Yelena would crouch down and hide in the aisle to monitor the situation behind her.

Lin Rui looked at the display screen of the tactical computer, and they had already walked a quarter of the way. Despite their cautious and cautious steps, they were still moving fast. The temperature in this passage was far higher than the outside, and Lin Rui even felt that he was sweating.

Suddenly, Lin Rui stopped and raised his fist - this was a signal to stop moving. Cliff stood in place, gun raised, slowly scanning the surroundings, looking for any signs of a moving enemy. He is a very sensitive person, born with the eyes, ears, and instincts of a scout.

"Engage the enemy ahead. Lin Rui's calm voice came from the communication channel, "The enemy troops are less than a hundred meters away from us, and they are ten degrees to the left in front of us. ”

"Understood. Yelena behind her replied in a low voice, she had already raised the muzzle of her gun.

"Estimated at ten, repeat, ten soldiers. It's those mercenaries. They move slowly, in a double-lined shape. We haven't been spotted yet. Lin Rui said in a low voice.

Lin Rui's idea was to avoid exchanging fire with the enemy as much as possible - after all, there were only two of them, and they couldn't risk a long battle. But the mercenaries were heading towards where they were......

"Kill them. Lin Rui whispered.

This group of mercenaries marched through the tunnel. Because he was wearing white snow camouflage. In the dark environment of the ground passage, the outline is clearly visible. There were ten of them, lined up in two teams, and the team members were about three meters apart.

Lin Rui was pleased to notice that these mercenaries looked very tired—only the vanguard and the two mercenaries at the rear of the palace were holding rifles. The others were talking to each other in whispers. This base has been occupied by them for a whole week, which is not only a torment for the Russian army outside, but also for these mercenaries.

The target is unpoliced. He slowly motioned to Yelena with a few gestures: back off until she was out of sight of the mercenaries.

Lin Rui turned on the team's internal communication frequency and said to Yelena behind him. "You can see them from your location, and let me know when they pass you. Mine had to take out the two in the back row first, and those two guys seemed alert. When the time comes, support me. Only silenced weapons can be used. Unless the situation gets worse, don't use weapons that make noise. ”

He paused for a moment, then ordered, "Action." ”

Lin Rui was armed with an AK-12 assault rifle, still hiding himself in the fork in the aisle, completely obscured by shadows.

A minute passed. Two minutes...... Three-minute ......

Two taps came from Lin Rui's headphones, which were messages from Yelena. The enemy is already approaching. Lin Rui relaxed his hand that pulled the trigger, jumped up and climbed to the top of the passage full of pipes, waiting......

Right there. Twenty meters away, the vanguard of this group of mercenaries walked to the front of Lin Rui's location. The mercenaries paused, their rifles equipped with tactical flashlights scanning the area vigilantly, and then slowly walked forward.

After a while, the remaining mercenaries appeared in Lin Rui's line of sight, about ten meters away from their vanguard. The headphones sounded again—and the two soldiers behind the mercenary pad passed by where he was.
