Saint Paul, the sewers.

The tunnel was filled with rubble, burying the lower passage, and the rolling dust had not yet settled, shrouding the tunnel.

For a time, coughs and shouts rose and fell.

"Wang... Wang Zheng! Wang Zheng!" Da Xiong's shouts seemed to be vaguely heard in his ears.

Wang Zheng shook his head and gradually regained consciousness. Fortunately, he was not buried by the rubble, but was splashed by debris, leaving many wounds on his body.

Wang Zheng, who survived, endured the pain in his body and crawled outwards. Next to him, several soldiers were buried under the rocks, their bodies broken, their heads deformed, and they were spraying blood.

Wang Zheng stared at their corpses for a moment, gritted his teeth, and continued to crawl forward.

"Wang Zheng!" Da Xiong was still shouting.

"I... I'm here..." Wang Zheng responded with a shout.

Da Xiong walked through the smoke to Wang Zheng and pulled him out.

"Arm... arm hurts a little." Wang Zheng replied, gasping for breath.

Da Xiong immediately shouted to the back, "Medic!"

The medic, with a red cross on his shoulder, hurried over through the smoke, opened the medical kit, and helped Wang Zheng check his injuries.

The medic deftly tore open Wang Zheng's sleeve, stopping the bleeding and bandaging him.

Xiao Jiu, his face covered in dust, also rushed over, and breathed a sigh of relief when he saw that Wang Zheng had only suffered minor injuries.

At the same time, Lao Hei adjusted the team and urgently commanded into the walkie-talkie, "The enemy has discovered us! Exit A has been blown up! The other three groups, charge up immediately! Our main force is behind us, hold on, and don't let the enemy destroy the remaining pipe exits!"

There were four exits in total from this underground pipeline. Lao Hei and his team were at the marked Exit A, while Hou Guoyu and the other two teams each led fifty men, guarding the other three exits.

"Roger!" At this time, Hou Guoyu, guarding Exit B, put down the walkie-talkie and waved his hand behind him, "Drones, launch!"

A member of the special operations team stepped forward and released a drone!

"Buzz..."

Accompanied by the sound of propellers, more than a dozen drones flew up the pipe, flying into the high altitude from the gaps in the railings.

According to the images taken by the drones, some Saint Paul soldiers appeared on the street and were quickly approaching the pipeline.

"Special operations team first!" Hou Guoyu ordered.

A dozen special operations team members immediately grabbed the ladder and climbed up one after another. While climbing, they took out special ceramic plates from their backpacks and stuffed them into the pockets of their bulletproof vests.

Hou Guoyu also followed. When everyone was about to reach the top, he ordered again, "Smoke grenades!"

The special operations team soldiers lying on the top grabbed the railing with one hand and aimed their automatic rifles mounted on their chests at the top of the pipe.

"Bang bang bang!"

A series of sounds like opening beer bottles rang out, and more than a dozen smoke grenades were launched out of the pipe.

These smoke grenades surrounded the pipeline, spraying white smoke as they rotated, quickly covering the exit.

Taking advantage of the spread of the smoke grenades, the special operations team members kicked open the manhole cover and jumped up, then set up their automatic rifles, protecting the pipe exit from attack.

At the same time, above the pipeline, Saint Paul soldiers who had been temporarily ordered to surround the area approached, and immediately reacted when they saw the white smoke.

"They're out! Attack!"

With a loud shout from the commander, more than thirty soldiers who had surrounded the area opened fire on the smoke area, regardless of whether they could see anything. These people were all garrison troops assigned to patrol the city, and they had also received temporary orders to surround the area, so there were not many of them.

"Da da da!"

The bullets passed through the smoke. Although most of them missed, the dense network of fire still knocked down several special operations team members, and screams rang out for a while.

At the same time, the special operations team members also activated their thermal imaging and opened fire on the enemy!

"Da da da!"

A row of bullets swept out, and three or four Saint Paul soldiers exploded with blood mist and fell into the pool of blood.

"Blast them to pieces."

Following the roar of a Saint Paul commander, a bundle of TNT explosives was thrown over. But because of the smoke, the position was a little off, and it landed not far away.

"Boom!"

A huge explosion roared, and flames and gravel flew everywhere!

Four or five special operations team members who were relatively close were immediately blown away by the explosion, leaving a large pit directly on the ground.

One of the members had both legs blown off, fell into the pool of blood, and passed out.

Hou Guoyu, covered in ash, climbed up from below with swift movements, and roared, "Spread out! Don't let the enemy concentrate fire!"

"Da da da!"

Bullets crisscrossed in the air. Relying on his excellent marksmanship and strong psychological qualities, Hou Guoyu killed four or five enemy soldiers who wanted to approach.

At the same time, most of the squad had left the pipeline and dispersed in all directions,迎击四面八方的敌人。

The two sides fought fiercely, and people were constantly hit and fell to the ground. Some quickly got up and continued to fight, while others lay on the ground forever, never to wake up again.

Seeing his comrades getting fewer and fewer, Hou Guoyu's eyes turned red. He had already emptied four magazines, and the barrel was scalding hot!

"Damn it, contact the main force! Ask them when they will arrive! How much longer!" Hou Guoyu roared.

"Keep bombing! Up, up!"

Just then, the commander's roar came from the crowd opposite.

Hou Guoyu immediately turned around, raised his automatic rifle, listened to the sound to identify the position, and aimed at the person who had just roared in the crowd.

"Bang bang bang!"

Three shots rang out, and the commander's head exploded with blood, and he fell to the ground.

Even so, his order had been conveyed. Hou Guoyu reversed his gun, trying to find the person responsible for throwing the explosives.

On a small building in the distance, a soldier lit two TNTs and was about to throw them over.

Hou Guoyu spotted the target in time and raised his hand for three shots.

"Da da da!"

The soldier's head was blown apart, one TNT dropped to the ground, and the other was thrown out, landing near the pipe exit.

Hou Guoyu's scalp tingled. He didn't hesitate at all, raised his foot and wanted to kick it away, because once the pipe exit was blown up, his side would definitely be wiped out.

At this moment, the member whose legs had been blown off before woke up. Compared with Hou Guoyu and the others, he was closer to the explosives.

Looking at the explosives falling in front of him, and then looking at the comrades lying in the pool of blood, he struggled forward and roared, "I... I... I'll do it!"

"Boom!"

The explosives exploded directly in mid-air, and the fire instantly engulfed him and four or five enemy soldiers around him. When the smoke cleared, the ground was full of corpses...
