The attacks of Sausage, Sergey and others gave other team members a gap to rush in. Scarface, Yelena and others also broke in from the entrance. In this underground space, the battle started to become more intense.

When the explosions and gunfire gradually ceased, these Red Tide team members realized that their companions had lost more than two-thirds. While they communicated loudly requesting support, they began to withdraw gradually.

Lin Rui, who was in the water, poked his head out, heard the voice of the people behind, suddenly turned his head to the back and swept the shuttle with the M4A1 automatic rifle in his hand, and directly knocked down several Red Tide players who were shouting at the communication. These Red Tide players were finally beaten back. Lin Rui climbed up from the water, this period of diving and the previous run consumed a lot of his energy.

After landing, the water on his body made him feel a chill. Fortunately, this was not sewage, but groundwater used to test the impermeability of the sewage tank. If it was the sewage from the uranium mine, he would not have the courage to jump down. At this time, the Scarface and others who were in charge of leading the other team members had merged with the crazy horse coming up from the bottom of the sewage pool on the other side, and they all gathered when they saw Lin Rui coming up from the water.

"Boss, they withdrew." Sergey walked over with a gun.

Shaking the water from his hair, Lin Rui ordered in a low voice, "This is only temporary, pay attention to all, and be prepared for battle. We will continue to advance inside and remember that we are not allowed to shoot without an order. We can't fight this tough battle. A. Even if we don’t care about casualties, our ammunition consumption can’t stand. Check the body to see if we can replenish ammunition.”

The sources of weapons for terrorists are very complex, from the original Soviet system, the US system, and many European countries. It is not easy to get supplements from them, but these red tide players are more sophisticated and equipped than terrorists, and most of them use NATO-standard equipment. This makes it easier for O2 players to get some supplies from the bodies of these red tide players.

The road in front was divided into several branches, and Lin Rui seemed to feel a certain danger when looking at the dark space ahead. He whispered to the team to stop advancing, and ordered Sergei and a few mercenaries who followed closely to investigate further.

A few minutes later they came back, and Sergey Hui reported, “One of the passages in front has not yet been completed, and the other is too narrow for traffic. If these red tide elements just came out by car, then they can only use the one on the right. This is the main channel for entry and exit of this underground facility. Due to the need for maintenance vehicles and larger equipment to enter and exit, this underground road can pass large vehicles."

"Is there any enemy intelligence?" Lin Rui asked.

"We heard some movement, but in order to avoid drawing attention, we did not go further." Sergey replied.

"Good job, that's it. Sausage, how is your explosive device?" Lin Rui turned his head and said loudly. "We don't have much time, they will definitely organize the fighting force to come out again."

"It's almost there, but the scene will be a bit bloody. I can't blame me. I have to find something to hide these explosive devices, so I can only use the corpses of the few red tide players." Sausage shook his head. He placed several explosives in order to prevent the enemy from using vehicles to forcefully break through. Although these red tide players are tough, they may also withdraw at a critical moment to preserve their strength. I have to guard against this move.

Sure enough, after waiting a few minutes. There were people on the opposite side slowly approaching under the cover of vehicles. These were several small engineering pickups. But they stopped advancing halfway through. Instead, a red tide militant bent over and rushed forward quickly.

Seeing that the enemy convoy suddenly stopped advancing and dispatched scouts, Lin Rui whispered to Yelena who was lying on the side: "Viper, kill a few scouts when the enemy is approaching the minefield, so that the enemy cannot find explosives on the ground. Yelena promised to put the silencer on the muzzle in a low voice, and aimed at the forehead of the scout who was walking in the front.

"Puff puff, puff puff", when the enemy approached the vicinity, Yelena's sniper rifle fired quickly, and with the faint shots, several scouts fell to the ground after being shot in the forehead.

The enemy in the vehicle saw that he fell to the ground. Before Commander Gu Jita gave an order, a dozen soldiers on several trucks quickly jumped out of the vehicle, lying on the ground and shooting in the direction of Yelena. The machine gun on the car also spewed fire snakes towards Lin Rui and the others. But in the midst of the violent gunfire, they did not find Yelena who was silently shooting.

"Damn, stop shooting. Whoever told you to shoot, head towards the main entrance." A red tide militant with the appearance of a small captain in the car cursed and ordered his men to move forward, sitting in the cab of the truck. The telescope carefully observed the movement ahead.

The Red Tide soldiers lying on the ground and shooting did not see the opponent's counterattack, and they stood up and followed the pickup truck that was moving forward. This is a standard squad coordination tactic. It uses the on-board firepower of armed vehicles as a cover, and then the infantry follows up, which can form a rapid tactical advantage in a local area.

At this time, Yelena who was shooting was finally caught by the enemy. The Red Tide team leader raised the walkie-talkie in his hand and called out loudly to the radio, "Damn, the enemy has no heavy weapons, what are you afraid of! First, give the sniper in front of you I'll kill it. Immediately!"

He shouted into the walkie-talkie for a long time, but there was no answer in the microphone, but a bullet from Yelena came.

After Yelena wiped out several rushing enemies, she suddenly found a red tide armed man who was hiding on the side of the truck behind and shouting with a walkie-talkie. Yelena sneered and turned the gun and fired a shot at him. The bullet rubbed the arm of the red tide leader and hit the truck door. The leader of the red tide team threw the walkie-talkie away and rolled over under the car.

The machine gunner on the truck heard the command of the team leader and saw Yelena from a distance. He immediately turned the machine gun on the vehicle and aimed it at that position. Yelena put on the sniper rifle magazine. Before she could pull the gun, she saw that the enemy's machine gunner was turning the muzzle. If she knew it was not good, she immediately rolled back holding the sniper rifle.

"Da da da da", the 7.62mm bullet accurately landed where Yelena was hiding, and the bullet hit the concrete pillar and the ground to sparks. The overwhelming concrete debris and dust covered Yelena, who had just rolled behind. She was a little fascinated by the dust, and temporarily suspended the sniper cover.

Without Yelena's sniper cover from the side, the enemy quickly rushed towards this side. Lin Rui ordered the team members to fire on the spot and ordered the sausage to kill the truck first. At the same time, he poked his head anxiously from the corner and looked into the distance.
