I don't have a system but I have a hammer

"Drip drop~"

Sure enough, if you say Cao Cao, Cao Cao, I was secretly regretting it. Suddenly, a rapid alarm sounded from the monitor in front of Correspondent A, which made everyone look solemn, because the various departments in the general command post, No matter what problem is encountered, it is impossible to use alarm sounds to convey information, unless the alarm information is automatically transmitted by a sensing device...

in other words…

"Commander, something happened to the underground pipeline!!"

"Wolfdog, let's go take a look!"

I raised my hand and said something to the wrist screen, then turned to look at the big screen above my head, my eyes full of solemnity, because at this time the correspondent had adjusted the picture of the alarm position, and what was shown on it turned out to be several aunts tearing apart pipes. Refined…

"Er ha! Go get the No. 5 counter bomb!"

When I saw this, I didn't dare to be negligent. I immediately looked back at the auditorium behind me, only to find that Erha had already spoken one step ahead of me. He opened the door to the central control room with a sharp expression, put on his helmet and walked away...

Seemingly infected by his fierce style, other people began to come forward after Erha left. There were even a few activists who had already hurriedly undressed their military uniforms, revealing the combat uniforms they were wearing, and were ready to go out to fight...

"Commander, I'm going too!"

"I've been sitting for too long, it's time to move around..."

"I'm going to help, I'm going to help!"

"Hmph, let's see how I can deal with these alien bugs!"

"... "

It's a pity that the enthusiasm of the militants was cooled to ice by my next words...

"The space in the underground facilities is only so big, and the passages are even narrower. Now that you are here, are you helping? Or are you not helping? Don't you have any idea in your mind?"

"... "

Seeing me suddenly choking, several people were stunned for a moment, looked at each other, and could only sit down again with an expression on their faces...

"Commander-in-Chief, there's a situation!"

However, at this moment, Correspondent C suddenly noticed something and his expression changed, and he quickly turned on the loudspeaker. The next second, Eagle Girl's extremely serious shout came out...

"Crazy gangster, the second wave of mechanical monsters is coming!!"

…………

[At the same time, in an underground pipe four kilometers away from the general command post, ten Blood Demon warriors were digging in the direction of the command post, sparing no effort to dig. The ground was full of broken pipe remains and pieces of soil of various sizes. Judging from the progress, they will be able to enter the engineering arsenal below the second line of defense in less than ten minutes...]

[However, at this moment, a Blood Demon warrior who was digging at the front suddenly stopped what he was doing, and raised his hand to signal other companions to stop digging. After everyone was quiet, he leaned forward slightly with his upper body and I put my cheek against the rock wall in front of me and started to listen...]

【咚～咚～咚～咚～】

[Soon, a sound of hard objects hitting from small to loud, from weak to strong, continued to be heard from the other side of the rock wall, and it became increasingly clear and audible over time. It was obvious that someone was doing it on the other side. Reverse mining work...】

[Hearing the change in the impact, the leading Blood Demon warrior stood still for a few seconds, then suddenly stretched out his claws and began to dig up the soil. The other companions also followed the same example. It only took less than twenty seconds to reach the ground. A U-shaped ceiling less than one meter wide was dug above the earthen path. They jumped up one after another, supported the earthen walls on both sides with their hands, stuck their bodies into the groove, and laid an ambush with ten people connected head to tail. On the top, silently watching the rock wall in front and below that was still making noise, obviously prepared to jump down and attack as soon as the enemy appeared...]

【咚～咚～咚～咚～】

[As time passed by, the impact on the other side of the rock wall began to become clearer and clearer. It was also accompanied by a faint clicking sound like stones rubbing against each other, as well as a few inaudible shouts. Voice…】

"Is it OK? Is it OK?"

"Don't make any noise, we'll get through in thirty meters..."

"Remember, stop when you reach five meters!"

"Oh, I got it, I got it..."

"... "

[As the content of the shouting shows, just after drinking some syrup from my aunt, the continuous banging sound suddenly stopped, followed by another burst of shouting, but the tone was full of A bit nervous...]

"Leader, we detected that there is space behind..."

"Is there a heat sensor signal?"

"No...no..."

"Go and take a look..."

"Huh? I...I'm going?"

"Idiot, there's a drill camera!"

"Oh, yes, I forgot..."

"Work quickly!"

"Good good..."

[As the words fell, there was movement again on the other side of the rock wall, but this time it was a noisy and sharp sound of metal cutting and sawing. The sound was accompanied by a slight trembling sound, which was obviously the opponent's drill. Wherever local equipment comes...]

[But the Blood Demon warrior huddled in the groove above was completely unmoved. He even held his breath. There was not a trace of ups and downs or shaking in his body, as if he were ten figures inlaid on the ceiling. The statue of the devil makes people feel terrifying and awe-inspiring when looking at it...]

[And what their black hole eyes are facing is the rock wall below that is shaking faintly and dust is constantly falling...]

[Finally, with a cracking sound, a large piece of gravel was suddenly pushed out of the hard rock wall, and what emerged from it was an alloy drill bit the size of a human head...]

"Leader, it's clear!"

"Scan it and see if there's anything in there?"

"Hey, good!"

[There was a rustling sound, the drill bit retracted, and light appeared, but there was only a glimmer of light, which was not enough to illuminate the entire tunnel. However, the ten Blood Demon warriors above had tightened their muscles slightly, and all of them were charged with energy. Ready to go...]

[Soon, there was movement from the other side of the hole, but what popped up was not the so-called camera, but a thick metal pipe with a blunt head...]

[But after passing through the rock wall, the metal pipe showed no intention of stopping. It extended all the way forward until it was about thirty meters past the tunnel, and then stopped with a slight trembling. The Blood Demon Warrior above was a Fog...]

[But after a brief hesitation, they still did not choose to fall. After all, the situation on the other side of the rock wall was completely unknown, and we were in a high position, and by holding our breath, we could completely prevent the enemy from possible dust attacks, so it is best now The only countermeasure is to stand still and wait for someone from the opponent to show up or the hole opens up, and then it is not too late to take action...]

[But what happened next was beyond everyone's expectations. After the metal tube stopped extending, a powerful roar of a machine suddenly sounded from the other side of the rock wall, and gurgling water came from the metal tube. The sound, and the sizzling sound like beef fried in butter...]

[This sudden abnormality immediately made the Blood Demon warriors realize that something was wrong. The next second they reacted very quickly and divided their troops into three groups. They dug wildly upwards while the other group jumped down the tunnel and prepared to return the same way. Only one of them was left. The Blood Demon warrior in the front row raised his right claw the moment he landed and struck hard at the connection between the metal pipe and the rock wall...]

[However, it was too late. There was only a pop sound. Countless holes with only the thickness of a thumb appeared in the metal pipe, and strips of high-pressure water columns composed of transparent liquid were sprayed out from it, which was even accompanied by a burst of water. The gray mist of corroded metal and the extremely pungent smell...]

[In just a moment, whether it was the one preparing to escape, the one digging upwards, or the Blood Demon warrior whose right hand was raised in the air but had not yet completely fallen, they were all sprayed all over at the same time by this transparent liquid of unknown origin. Face…】

[Next second, stab la la la la~]

[The stench fills the air, and flesh and blood melt! 】

"I'll fuck you!!"

[Seeing that the ten blood demon warriors completely lost contact the moment the liquid appeared, my eyes suddenly twitched. I quickly stood on the snow throne and looked up at the snow and dust billowing in the distance. When I discovered that 5000 machines had just set off. Slave, when I had run almost six kilometers, I was so frightened that I shouted on the spot...]

"Damn!! Make them stop!!"

"what?"
