Number One Dungeon Supplier

"Get up! Get up!" The Demon Rat's Captains were shouting and making noises in their soldier's bunk. "The enemies had destroyed the Inner Walls, get your fucking ass up, grab your weapons and go!" The Captain said once before running to the next bunker to wake the other group of rats.

"The enemies had destroyed the Inner Walls?" The Demon Rats talked to themselves, as they could not believe the humans had such capabilities.

"Not sure, I did not hear a single thing right under here." Another soldier said as he asked for assistance wearing the heavy armour from another Demon Rat.

"Duh, of course, you dumbass. We are in the undercity, how the hell do we know what is happening at the top?" One of the assisting rats knocked his head while aiding him to click the back of his chest armour to the front.

"Well, I am just worried about my friend. He had been assigned to guard duty over the Inner Walls." The Demon Rat said as he thanked them for the assistance and began helping the rest to wear their armour as well.

"Hurry up you slowtards! Do you think the enemy is going to drink a cup of tea and wait for you? Get your ass out here in five minutes or else!" The captain shouted from the outside and the Demon Rats were already grudgingly acknowledging their captain's orders. However, since it was the captain that personally called them out instead of their platoon leaders, they could only assume that it was truly a mess up there since their higher ranks do not usually bother with them at all.

As the Demon Rat Soldiers were hastening their pace to wear their equipment, there was a ruckus outside as well with a team of support Demon Rats carrying large wooden crates right beside the captain.

Once more, the captain shouted and threatened the troops despite knowing that everyone was crazily wearing their armour and making sure they were ready for the battle. Soon, the Demon Rat Soldiers lined up in formation and awaited the captain's orders.

"If you slowpokes are not listening to what I had heard, the humans have once again shown that they are capable of destruction. They have destroyed the first and second layers of the Inner Wall while the third and final layer is barely standing despite our greatest effort to reinforce them previously." The Captain said and he was not wrong.

According to Sebastia before her stint in the Mecha World, she had been monitoring and gathering information about the Demon Rat's occupied city. The Northern Capital did not have such capabilities until the human's liberation of Town Wecha. Since then, they felt that they should bolster their defences even further in case the humans were daring enough to attack them.

They had also taken into account the huge gigantic one to one fights against their very own castle machinations and realised that the new humans that came to assist the Northern Region were dangerous. That was why they also wished to attack the Western and Eastern Kingdoms as they believed that they were the ones who had been training these humans secretly. (Or that was what the North and South Scholars believed since their communication between the East and West was not as amicable as they wished to.)

But because they only have suspicions, the now dead scholars thought to impose their suspicions as truths and even propagate them as dangerous threats to further challenge the rats to be better at their work.

So through their innovation and 'slave' work, they were able to create the third and final layer of the Inner Wall based on their accumulation of knowledge not from just the North and South Scholars but from their own desires to improve. (It's a pity that Jin could not capture them as they immediately turned into a resource or else, he would have a race filled with power hungry minions under his control.)

"Gentlemen! Your time has come to shine! To prove that we Demon Rats are the pinnacle race of modern society! Do not just push back the invaders but annihilate every single one of them! But do not capture for they will explode and die once they know that they are in that situation." The captain said and he could see a few disgruntled faces.

"So to aid all of you to do your jobs to the best of your abilities, the War Council had generously allowed each one of you to hold a rifle as well as your main weapon. The invaders are versatile and so are we! As you proceed to the main elevator up to the surface, take them and make sure to familiarise yourself with it before using them." The Captain ended his pep talk before taking a rifle for himself and proceeded to the elevator while the leaders of each platoon took over the rest of the procedures.

"Heh, using their own weapons against them, that will be interesting." One of the Demon Rats commented.

"You sure it's their technology? Perhaps they stole it from us in the first place."

"Or maybe some traitor rat gave it to them."

"Nah, can't be. Our technology is too unique for the likes of those humans. They probably took one, cheapened it and then modified it in such a way that it suits their primitive usage."

"Ha! Cheapened. No wonder I heard those humans were able to shoot only one bullet at a time."

"Exactly! Our Steam Rifles can shoot three bullets at one time and are much sturdier than theirs. They used a combination of metal and wood while ours are pure metal. Not to mention the ore we used from the lifestream to enhance the power of our rifles."

"But to think they are giving regular soldiers like us such a strong weapon, the situation up there must be madness." The Demon Rat Soldiers continued to talk to themselves as they picked up their new steam rifles and waited for the great elevator of the undercity to bring them up.

However, when the great elevator doors opened, hundreds of stretchers were seen being carried out of the elevator. The Demon Rats who were at the surface were wounded. Loss of limbs and tails to various sorts of debris being stuck in their bodies. They saw how grim it was for the initial group that was up there and those Demon Rat Soldiers braced themselves that the moment they reached the surface, it would be living hell.
