The demonic race of the abyss doesn't bother developing airships like humans do, because most of them have the ability to fly. Moreover, those who can't fly don't have the desire to, as they have survived in primitive environments and know that the more dangerous creatures often lurk in the skies, making it extremely perilous.
Well, I won't continue describing the ecology of abyssal creatures. After using teleportation gates in the demon world to reach the nearest city to the one under attack, our group, mostly unable to fly, rode earth dragons with the Demon King towards our destination.
However, this place doesn't look as modern as the Imperial City. Although there are various modern buildings, it resembles some third-tier cities. Some of the buildings even have cracks, possibly due to improper materials.
"Don't mind it," the Demon King said as we left the city gates. "It's just some creatures who like to live in mud piles, making their rooms too damp, causing the houses to crack. Don't worry about it."
"Well, there are many peculiar beings in this world that we still need to take care of. You're doing a great job," I replied.
"Haha... it's not that bad. By the way, there seems to be a time difference between here and there. When I descended here, it should have been several decades ago in the human world, hmm..."
"In the abyss, that would be centuries, huh? I can't believe you've stayed here for so long."
"It's because the Seven Sins sisters have been with me, so it hasn't been too boring. Plus, it took me over 200 years to conquer the demon world, so I've had plenty to do."
"Hey hey hey, this level of boredom is beyond normal. Most people play a game for a few years, and you've been playing for 200 years? What belief has kept you engaged for so long? And what game could challenge you?"
"Because..." The Demon King scratched his head. "Actually, I just happened to fall into the abyss at first, and even the respawn point was in the abyss. With no quests and almost nothing in the abyss, all I could do every day was grind! I recorded the characteristics of every monster, their weaknesses, and all the unique aspects of each map."
"I suddenly realized that I underestimated this guy in front of me. There must be a reason why he became the Demon King."
"So after unifying the demon world, I quickly summarized all the key points of the abyss, then handed it to the troops to deal with. It was resolved in no time."
"You did that..." The others were all amazed.
"Alright, enough talk. We've arrived." In the distance, a massive fortress surrounded by gray hard stones appeared before us... No, it wasn't a fortress, but a small fort on top of the city wall. I could even see the cannon barrels and observation posts on it.
And on the city wall, black giant cannons were aimed towards the sky... Are you planning to shoot birds with cannons? At least use anti-aircraft machine guns, right?
Although I know you don't have any.
"Lord Demon King!" A greedy teleporter appeared beside us.
"The enemy Undead Holy Angel squad has completed an attack, air-dropping a large number of mindless skeleton soldiers. Although they have been completely wiped out, due to their sheer numbers, they have caused some impact on our backup facilities. It's estimated that they will launch another attack this afternoon."
"Hmm, I see. They are actually using cannon fodder to deplete our long-range weapons... How are our other weapons? Can they engage in long-range attacks?"
"No, the enemy's position is completely out of range. It seems that after the first assault resulted in huge losses, they are now reluctant to attack directly and are using aerial forces, which are more difficult to target."
"What if we set up aerial mines?"
Aliyah suddenly suggested.
"Something similar to sky lanterns, so their air force can't just fly over?"
"But can't they avoid such things?"
"Just use time-delayed explosions, release them when they appear."
"Hmm..."
The Demon Lord pondered for a moment and nodded.
"Good point. Xiao Gan, make 500 sky lanterns for those bird people to play with."
"...My lord, what are sky lanterns?"
Despite Greed wearing a mask, I could sense her puzzled expression beneath it.
Hehe... What are sky lanterns... Hahaha.
*Cough cough...*
After some reflection, the Demon Lord took out paper and pen, quickly sketched something, and handed the drawing to the other party within a minute.
"Follow this drawing, attach a bomb with a fuse length of about a minute on top. Alright, go quickly."
With that said, the other party was immediately sent off.
I was curious about what she had drawn...
*Cough cough* In any case, the enemy is going to attack in the afternoon. Let's make some preparations."
"Are we just going to defend like this?"
"Because I don't want to waste troops clashing head-on with them, why waste manpower when we can use various long-range weapons to weaken them?"
"Perhaps you should buy electromagnetic cannons from us, it will show them who's boss in minutes."
"Electromagnetic cannons? You guys have indeed developed quite a lot..."
The Demon Lord shrugged.
"Well, it doesn't matter much, they are all more or less the same."
"Why do you use cannons? Wouldn't magic be more powerful?"
"But magic relies entirely on the user's visual ability, and even the farthest range doesn't compare to artillery."
"What about large-scale magic? Even I can use long-range massive attack magic like Eternal Frost Glacier and Ice Dragon Summon. While it may not be effective against very strong opponents, it's perfect for ordinary soldiers."
"Because... the enemy has necromancers."
The Demon Lord spread his hands.
"No matter how much you unleash, they can counter it. Believe it or not?"
"What the heck?"
"Why don't you try? We are at a stalemate anyway."
"Of course!"
Before I could speak, Bai Yueguang immediately interjected.
"Can we launch an attack?"
