The battle between the 7th Legion vs. the Allied Forces of the Various Kings took place at exactly noon.
　There were 10,000 opponents.
　If they fought in front of him, there was no way they could win.
　Kushana, the old general of Manticore, advises, "We must attack here by night.

'Shouldn't we launch a night attack here?

　'No,' I said, shaking my head.

''Humans are used to fighting the Demon King's army. They should be sufficiently prepared for a field battle. I'm sure they also have sorcerers who specialize in the use of light and search magic.

Indeed.

　Kushana agreed.

'And there are a lot of us. I'm sure the enemy knows exactly what we're doing by now. I think they're waiting for us to come to them.

　I blurted out a prediction, and my prediction was correct.
　The report came from Lilith, who had been sent out as a scout.

Ike-sama, as expected, the enemy army is completely aware of our movements.

　They are trying to meet us in this form of formation.
　I added.
　The shape of the formation Lilith showed was a U shape.

''I see, so it's a crane wing formation.
'The Crane Wing formation?'
'The crane wing formation is a formation used to encircle the enemy.
Is it a strong formation?
Well, that's the first rule of warfare.
Well that's not good.

　As expected, Lilith's voice is quiet, too.
　Perhaps it's because she's seen an army of ten thousand up close and personal, but she's feeling a little weak.
　Not to reassure her, but I'll explain the weaknesses of that formation.

''The Crane Wing formation is powerful. Adopting it would mean that the enemy commander is not incompetent. However, this formation also has a weakness.

A weakness?

''Yeah, the Crane Wing formation will inevitably be in the shape of a U. The advantage of this formation is that it is easy to encircle and annihilate a small number of enemies.''

''A few,'' isn't that the 7th Corps? Our legion has 2,000 soldiers. At this rate, we'll be at the mercy of the enemy.

''So I told you there are weaknesses. This formation is designed to encircle the opponent, so the bottom of the U is inevitably thinner.

Well, that's what happens when you put soldiers in uniform. But what does that have to do with weaknesses?

'Here's the thing: if you punch the bottom of the U in the letter U, the enemy will be cut in half.

　Even after hearing those words, Lilith frowned.
　It seems that this girl is not a general of the intellect type, after all, but a martial force type of general.

'Good grief,' the old Manticore general Kushana adds.

'In other words, Lord Ike said he would punch the bottom of that U, divide the enemy in two, throw them into chaos, and destroy each of the enemy armies that were split in two.

　After hearing Kushana's supplementary information, Lilith finally clapped her hands, "I see.

''So that's the role of my brigade, the Immortal Brigade, is it?

　Hearing those words, Kushana's eyebrows furrowed. Then she turned around to me and asked with a divine face.

''But even if we were to strike through the bottom of the enemy's army, will Ike-dono's brigade alone be enough?　Lord Ike's brigade numbers five hundred, and even if it's only temporary, you'll be surrounded by ten thousand enemy troops.

　I had no choice but to say that I was fine about it.
　As I've said many times, the general's weakness can be felt by the soldiers.
　He couldn't show a weak attitude here.
　Besides, by saying so, it would also inspire them to 'self'.

　Honestly, using only 500 troops to stall 10,000 troops even temporarily and try to break through the center was a stupid thing to do.

　I had never heard of challenging an army of 10,000 troops with a mere 500 troops, regardless of the ancient or modern world, or any other world.

　The act I'm about to perform is an act that is ridiculed as folly by the great generals of every world.

　--But.

　I muttered to myself, and I was ready to go.
　Even with only five hundred men, there was nothing I couldn't do.

　After all, I had the Ouroboros Staff, which I had inherited from my grandfather, and the flintlocklock gun, my most powerful weapon.

　When I was sure of this, I led the Immortal Brigade into the enemy camp.
　What would the enemy soldiers think when they saw the brigade of only five hundred men charging into them?

　They might also think that the boardmen of the Demon King's army were recklessly charging into the enemy's camp.

　That's what the Demon King's Army is all about.
　There are few generals who think intelligently.
　However, it was convenient for us if you think so.

''The more you let your guard down, the more you let your guard down. The more you underestimate me, the more you underestimate me, the more I am grateful.

　While saying that, I straddled my beloved horse and took the lead.
　Seeing that figure, Lilith says.

''Members of the Immortal Brigade, continue to Ike-sama!

　With those words, the Immortal Brigade guys followed my back.
　When I confirmed that, I unleashed a huge "Barrier" magic in front.

　This is because they were well versed in the humans' fighting techniques.
　First, long-distance shooting with the bow, that was their usual method.

　Last time, the magic of the 《Storm》 prevented it, but this time it was a regular army.
　They chose the magic of the "Anti-Wall" in anticipation of having more powerful "Fixed Battery (Ballista)" and the like available.

　However, the magic of the "Wall Defense" is more difficult than expected.

　It's easy to create a barrier to protect an individual level, but deploying a barrier to protect an army requires powerful magic power, casting time, and a knack for it.

　I stopped my beloved horse and started chanting my magic.
　I had to build a huge defensive wall, I needed time to focus.
　In the meantime, the arrows fired by the enemy arced and came towards us.

''.........Will I be able to make it in time?''

　That's what I thought, but I manage to get there in time.
　A huge barrier unfolds in front of me.　
　Something like a pale retina is deployed.
　The barrier causes the arrows fired by the humans to veer off course one after another.

What the hell is that huge barrier?　Not only do you play bows and arrows, but you even play ballista?

　I could almost hear the humans' voices up here.
　If I could have explained to them, I would have replied

'A mere barrier won't prevent you from getting to the ballista.

　And--.

　The barrier I deployed had a little trick up its sleeve.
　Rather than just deploying a flat barrier, I made the barrier itself curved.
　That way, the force of the bow and arrow would be reduced and its trajectory would be changed in a different direction.

　With a flat barrier, that force would be concentrated in a single point, and there was a chance that it could be broken, but if all you wanted to do was to deflect it, a sphere would be much more efficient.

　There's also the memory of previous lives involved in this area.
　I'm talking about the field of physics.

　It's not that I'm not a big fan of the idea.

　--No, I guess I'm smug.

　I'm not sure if I'll ever be a loser if I don't think so.

　As I was reminding myself of this, Lilith, my second in command, poured cold water on me.

''As expected of Ike-sama. I didn't expect you to use such brilliant magic. --Oh, no, of course I expected it, but it was more than I imagined.

You can't coax me out of this one.

　Then she stuck out her tongue and said, "Tsk," she said.

　The next person who called out to me was Giron, the orc's chief of staff.

''Sir, the gun crew is ready, but do you mind if we fire already?''

　Come to think of it, I had completely forgotten that this guy had been brought to the battlefield as well.

　I was surprised when he made a suggestion that was unusual for a chief strategist to make, but I stuck out one hand.

Not yet. It's too early.

　I conquered.

'But the enemy forces are that close to us. A firearm can reach about four hundred meters, can't it?

'You can reach what you can reach, but if you don't hit it, it's useless.

　The flintlock gun is not much different from a modern gun in terms of power, but its effective range is much shorter.

　If the flintlock gun was to be used effectively, its range would be limited to 50 meters at best.

　In short, it would have been useless if the enemy hadn't come closer.
　However, I'm not worried about that point.
　I can easily understand the reaction of the enemy forces when they find out that their bows and arrows are ineffective.
　If you look at it, the enemy army was right in front of you.

　It seems that the enemy, realizing that attacking with bows and arrows is useless, has quickly switched their attack methods.

　The best way for the knights to attack, the lance-charge, was the best way for them to attack.

　The knights approaching with a cloud of dust.
　They are all dressed in heavy armor.
　Each of them is holding a long spear for the assault in their hands.

''That's amazing.''

　Giron gulps as he says this.
　I certainly marvel at it, too.
　An assault on that scale is not something that is seen very often.

　If this were a scene from a movie, it would be a lot of fun, but for those on the receiving end of that assault, it's unbearable.

　In fact, many demons had lost their lives in that assault.
　However, that shouldn't be the case this time.
　No, I didn't intend to let them do that.
　That's why it's a flintlocklock gun.

　I gave my men orders again, "Draw the enemy soldiers to the edge," and waited for the knights to come in front of me.

　It would be standard practice to wait until you can hear the knights breathing, but this is the first time I've done this.

　I decided to shoot with plenty of time to spare.

　When the enemy soldiers came within 30 meters of me, I swung my raised right hand down and

Shoot!

　I ordered.

　A roar echoed around the area.
　Instantly, the knights collapsed.

　The ones that were hit by bullets collapsed on the spot without exception, and the ones that were hit by horses were pushed off their horses.

　The moment I saw that scene, I was convinced that this battle was won.
　The next gun team that finished shooting was replaced by the next one.
　It's called a three-step shoot.

　The second and third shots were fired at the knights who were lucky enough not to be hit by bullets or who only fell off their horses.

　The knights fall down each time.
　The horses that have lost their masters are left to die on the spot.
　The surviving knights seem to have lost the will to fight.

　The brave knights who had strode through so many battles began to run away from the battlefield.
　In other words, the bottom of the U-shaped formation had collapsed.
　My purpose was now accomplished.

　All that remained was for the remaining brigade commanders to intercept the enemy army that had been divided in two.
　Of course, I had no intention of playing around in the meantime.

　I'm going to be covering for the allies, but it's true that I've had time to breathe a sigh of relief.

　I look at the enemy lines from a distance.
　A fierce pillar of fire and a thunderbolt could be seen.

''........Speaking of which, was the right wing commanded by the commander?

　It's no wonder that a flashy battle is going on.
　Without hesitation, they must be firing a series of forbidden grade magic.

　Their formation was cut in half, and one of the best witches in the Demon King's army was fighting with all their might. The enemy must be in a state of panic.

''-- Then...''

　I said, and decided to head towards the left wing.

　This one was supposed to be commanded by Kushana the Manticore and Bayo the Werewolf.　

　Even though they had cut the enemy in half and were in a state of depression, the numbers might be too much for them to bear.

　With that in mind, I order my chief of staff, Giron, and his second in command, Lilith.

''Let's go cover the left flank!

　They both said at the same time, "Yes! I nodded.


　The Immortal Brigade's men followed behind me in a single, unbroken line.
　A few moments later, the divided knights began to crush at almost the same time.


　Thus, in later times, from the Demon King's Army's side.

"Miracle at Arsenum.

　From the human side.

The Humiliation of Arsenum.

　And the battle as it was called was over.

　In short, it was an overwhelming victory for us.
