"Captain, you have to abandon the docks, and in 12 hours the zombies will attack the dock defense from the rear through the pipeline system."

A voice suddenly came from behind Thompson, and when Thompson turned his head, he saw the busy command team, and there was no one behind him.

"Who, who was talking to me just now?"

Thompson asked aloud, and the busy crowd looked up, each with a look of confusion.

Thompson asked three times, but everyone shook their heads, and Thompson, who was in a terrible mood, left the porthole and went to the back of the podium.

The staff officer poured him a glass of water, and Thompson took two sips in a muffled voice, and he suddenly remembered a question, and Thompson asked the staff officer in charge of the field situation:

"Is there a complex piping system under the dock? Check me out right now for the sewer blueprints. ”

The staff officer immediately called the data in the database, and soon a complex pipe network diagram was presented on the computer, and he saw that the map was like a spider web, and the staggered pipe network densely covered the entire underground of the dock, and Thompson's face immediately became ugly.

"To arrange two reconnaissance teams to go down, it is necessary to ensure the safety of the position."

……

Hewitt tugged open the sewer manhole cover, and a rancid smell poured up from the pipe. Hewitt shone his flashlight underneath, and the sewers were so misty that he couldn't see anything.

"Alright, let's go down!"

Hewitt waved his hand, and he climbed onto the iron handrail, and Hewitt entered the sewers.

Two other teammates followed him, and after climbing five metres, Hewitt let go of his left hand and jumped into the sewage that didn't reach his instep.

This is the huge network system under the New York Harbor, and just now, the dock garrison received an order from the aircraft carrier to inspect the sewer network, and the aircraft carrier is worried that the zombies will break through from the ground.

The sewers at the dock were thicker than those in the city, and Hewitt stood inside the pipe as if he were in a tunnel, and the "tunnel" was filled with a fog that could only shine six meters overhead.

"Test the communication system", Hewitt pressed the headset, a clear sound came from the headset, Hewitt waved his finger, and the three people held the gun and slowly headed towards the depths of the pipe.

The inside of the pipe has been shielded from the smoke of the dock, and it is very quiet, except for the sound of water under your feet.

Twenty meters later, a fork in the road appeared, and Hewitt installed an infrared detector on the fork, and the three men entered one of the passages.

The sewage here is a little deeper, the cold sewage is no longer up to the knees, and the chill seeps into the skin, and Hewitt and the others feel very uncomfortable.

The sound of dripping water echoed through the pipes, adding to the tension in the place, and suddenly a black mass fell from the walls of the pipes, and the mass fell into the sewage, "plopping" like thunder.

With a "hmph", the muzzles of the three guns turned around in unison, and the hearts of the three people instantly lifted.

Hewitt saw a rat floating on the water, and the rat shook it in the sewage, and it swam towards the shore, and Hewitt was relieved.

"Lifted, it's a mouse."

All three breathed a sigh of relief, and Hewitt installed the monitor at the second fork as they continued deeper into the pipe.

According to the pipeline network line, Hewitt and others inspected most of the pipelines underground, installed 32 monitors, and basically monitored all the sewers leading to the dock, and the command system of the aircraft carrier could already show the underground situation.

It was a three-dimensional hologram, and the installed monitor was represented by a green dot, representing the yellow dot of the reconnaissance team that was still advancing, and a "beep" sounded, and the thirty-third green dot lit up.

"Captain, it seems to be okay now."

The staff officer and Thompson stood together, and the two men looked at the picture and whispered. Just as the staff officer was about to make a judgment, he heard a "beep" sound, and a green dot in the left corner of the hologram suddenly turned red.

"What's going on?"

The staff officer's face changed, he stared at the red dot tightly, and the staff officer reported:

"When the light turns green, it means there's a large object passing through."

Thompson's face twitched, and before he could reply, there was another "beep", and a green dot in the right corner of the hologram also turned red.

The monitor tends to turn red like dyeing, and once it sounds, the "beep" sound continues, and you can see that the outermost green dots on the hologram begin to change one by one, and they spread towards the yellow light.

"Attention of the reconnaissance team, attention of the reconnaissance team, there is an unknown object heading towards you, withdraw immediately, order you to withdraw immediately."

Hewitt had just finished installing the thirty-fifth monitor when an alarm came from his individual command system - all the monitors that had been installed before had been triggered, and the red light was coming towards his position.

The three of them immediately turned back nervously, and they pointed their guns at the pipe behind them, and everyone could hear the "pounding" sound of their hearts.

"Captain, what should I do?"

Team A asked quietly, and Hewitt could feel his voice tremble, but nothing could be seen inside the dark pipe.

In the individual computer, the red light did not light up all the passages, some of the sewers were still green, Hewitt gritted his teeth, he jerked away the weight on his back, and Hewitt rushed towards the pipes that represented safety.

"Follow me."

The three men ran desperately in the pipe, the sewage splashing high under their feet, and they had only rushed ten meters before a fierce gunfire was heard from inside the headphones - another reconnaissance team had already encountered the enemy.

"Hurry, hurry, hurry!"

Hewitt shouted, and the three men rushed through a fork in the road, where the green was still flashing.

But when they had gone twenty meters, the individual system sounded the alarm again - the green light behind them had turned red.

"Don't look back, watch out for grenades!"

Hewitt shouted, and he dropped a grenade behind him.

Three seconds later, there was a "boom" in the pipe behind him, and the sewer shook violently, and a turbid wave sprayed over, and the shock wave was like a heavy hammer, and the three were thrown out fiercely.

"Uh......"

The howl of zombies was clearly heard from the explosion, and the faces of Hewitt and the others immediately turned white.

Without bothering to wipe the sewage off their faces, the three of them crawled to their feet, and they rushed out again in front of them.
