In the underground pipes, Xiao Er, Su Jianqing, and Kai unloaded their mechas, held laser cutting guns, and crawled in the dirty, foul-smelling sewage in armor, and the pickled things in the sewer pipes made people want to vomit when they looked at them, but thanks to the fact that they were wearing sealed helmets, they couldn't smell the smell here, otherwise, the three of them would have to vomit.

Xiao Er secretly scolded in his heart, these students who were cheating on the stall were really the sins he had created in his previous life, and he was a dignified senior mechanic who actually became a ground rat in the sewer pipe.

On the ground, Zhang Yueyue carefully watched the direction of Xiao Er in the positioning system, constantly correcting their moving direction.

Shore took the lead and kept advancing, and after passing through several passages, they finally reached the main pipe, and no longer had to crawl through the narrow pipes.

As he walked, Shore stumbled upon several footprints in the mud of the pipe, which were obviously larger than human footprints, and Shore had some doubts in his heart.

At this moment, Zhang Yueyue informed Xiao Er in the communication channel that they were about to reach the bottom of the arsenal, and after that, the signal interfered, and Xiao Er cut off their contact with the ground.

Shore and the others walked a few hundred meters and saw a pipe that ran upwards, and Shore decided to take this pipe, and the three of them began to drill these narrow sewer pipes again.

Suddenly, Xiao Er stopped moving forward, Su Jianqing hit Xiao Er's buttocks, and the sewage on Xiao Er's buttocks stained Su Jianqing's helmet, Su Jianqing scolded: "Instructor, you are doing chicken feathers!" Why did you suddenly stop climbing? ”

"Don't talk!" Xiao Er scolded Su Jianqing in a low voice.

Su Jianqing was startled and asked in a low voice, "What's wrong?" ”

In front of Shore was a small metal mesh door, which had apparently been designed by the designers of the arsenal launching system to prevent animals from getting in, but now that the metal door had been destroyed, the little finger-thick steel bar had been broken in two, and the fracture had apparently been cut with a cutter, and had just been cut.

"Aliens may have entered the arsenal through the sewers!" Shore frowned.

"What? Aliens also like to be ground mice? How could they have thought of entering the arsenal through the sewer pipe? Su Jianqing asked in surprise.

"You're smart, can you come up with such a bad idea? The Alagan people have a much higher IQ than humans! ”

"An outer space baboon can think of such a bad idea?" Kay asked.

"How is this a bad idea? Can you think of a better way? Su Jianqing argued.

"The metal door in front was clearly cut by a cutter, and there is no rust on the port, indicating that it was just cut! I've just seen a few larger-than-normal footprints in the mud of the main pipeline! Do you say it's not aliens in the pipes? Shore explained.

"Looks like we're going to have to be careful!" Kai whispered.

All three pulled out their pulse pistols.

In the pipeline ahead, Shore actually found an alien leaving a mark, and the alien may have figured out the route into the arsenal. With the clues left behind by the aliens, Shore and the others speed up their advance, these aliens enter the arsenal with obvious ill intentions, and Shore must stop them.

Soon, Shore and the others had climbed to a high platform, and the manhole cover at the top of the platform had also been destroyed.

Shore cautiously climbed up to the platform, and a narrow passage appeared before him, with a row of dim lights flashing on the top of the passage, like an underground corridor, and they really had to enter the interior of the arsenal through the sewers.

Xiao Er took Su Jianqing and Kai through the corridor quickly, and there were no signposts in the corridor, so they could only rely on luck to find the exit and find the defenders in the arsenal.

As they walked, the corridor branched out into many forks, and the whole underground passage was like a labyrinth, and they had already turned to find the exit.

"Instructor, did we encounter the ghost in the novel hitting the wall? Why can't I find an exit for half a day? Su Jianqing joked.

"The devil hits you in the head! No knowledge at all! Shore said angrily, "This way of line design is a common routine in military installations!" The engineers are specially built into a labyrinth of wiring inside the military facility, in order to prevent spies from sneaking in, and most ground rats like us will get lost! I guess the alien rats are also spinning around in this maze! ”

"So should we find the exit before the aliens find it?"

"Then what are you two talking about here? Why don't you hurry up like a solution? Shore said angrily.

The three of them went around and around the maze, and actually found the exit by mistake, which was so lucky!

But when the three of them went up to the other level of the arsenal, they found that they had entered another labyrinth, but this labyrinth was obviously easier to walk, because this floor was already the warehouse of the arsenal, and each compartment was equipped with huge iron doors, and the corridors became more spacious.

The three of them went up to the three-story warehouse in a row, and at a fork in the road to find the exit, they actually collided with three sneaky aliens.

The three Legitans were obviously slow to react, Shore raised his hand and fired, killing two Legantas in an instant, but there was still one Legita who opened fire, and the bullets of the submachine gun shot out in a row, and the trajectory of the bullets flew past Su Jianqing's helmet.

Kai killed the last of the Regetans with a single shot.

Su Jianqing's expression was dull, and he felt like he was about to be scared to pee, God joked with his life for the second time today!

The continuous sound of gunfire attracted the attention of soldiers who were carrying ammunition in the warehouse.

The soldiers who arrived pointed their guns at the three foul-smelling, dirt-covered monsters, and looked at the corpses of the three Legtars on the ground, and were shocked. Xiao Er explained to the soldiers and asked to see Zhao Xin, the commander of the 249th Regiment of their 711th Division, but the soldiers did not know any Zhao Xin, so they could only take Xiao Er to meet their infantry commander.

The infantry commander was naturally still a knowledgeable person, and after Shore introduced his situation to the regiment commander, the regiment commander was suspicious, but paid special attention to the alien infiltration, and ordered a company of soldiers to inspect the inside of the armament depot.

Su Jianqing asked that soldiers must be sent immediately to protect the core system of the arsenal, the general control room and the power station, the infiltrated aliens will obviously use these important military centers as the target of destruction, whether it is the general control room or the power station, if it is destroyed by aliens, Su Jianqing's purpose of this trip will be completely defeated.

The infantry commander contacted Commander Zhao Xin, whom Xiao Er knew, and several other regiment commanders, and after some arguments, everyone agreed that Xiao Er and them entered the general control room, and sent a system operator from the previous general control room to cooperate with Su Jianqing and several soldiers to protect their safety.

When Su Jianqing and the others entered the general control room, an hour had already passed!

Su Jianqing looked at the dozens of dark display screens in front of him, came to the main console, took off the stinking armor that affected his mood, stretched his waist fiercely, and shouted: "It's time to show your true strength!" Let's fight! Let's fight! ”
