I Become a Staff Officer in the Demon Army, but I Can Only Do Office Work!

At that time, Hel Arche, the Demon King, was on the battlefield.

Not returning to the castle of the Devil's Capital, Groth Stadt, but at the Hyvar position, where the rain of steel poured down, she was fully open to all the power she could have.

"- Go to hell." Genocide Byrne "!

With the movement of Hell Arche's arms, the earth burns up.

A blast of flames and blasts overshadows the human army and stops its advance. But still, the human army won't stop attacking.

"Sire, it's up there!

"Colour!?"

A chunk of iron had fallen in the direction of one of the SS's screaming fingers.

It's the "shell" where Akira says it is.

The shell landed near Hel Arche, at a point a dozen meters ahead, followed by a very close one, a few meters rearward.

On the brink, one of the SS deployed defensive magic to prevent it, but nothing more could be done.

Because the shells are too powerful.

"Your Majesty, we are still jilli poor. Step back!"

"Right. Failure is a good place to fall two positions in just a few days, but it's better than dying. Abandon the Heyvar position. The defense team is retreating, we will serve the lord!

"" "As you wish!

But that being said, the onslaught of the human army is terrific.

The SS were right, they were jilli poor.

But the withdrawal of the defensive forces takes time. If we do not buy a little time, the damage will not remain just the renunciation of the position.

"Ginzer, you take the right wing. Kreutzel is on the left wing. Rosen is with me. Look at the gap. Attack, tow and stop the enemy's legs."

"" "Ha" "

Hel Arche commands the troops and hits his enemies with his own magic when he sees a gap.

But the human army is attacking from across the horizon.

It is the soldiers known as "artillery" that make it up. A revolutionary weapon that has a range of more than ten kilometres and says it delivers five to six rounds of artillery to the battlefield every minute with the combined power of a highly challenging fire magic used by high-ranking magicians.

Even with SS defensive witchcraft, it's finally time to prevent it.

Again, defensive magic cannot and must not completely prevent a blast.

Because if it is completely sealed, it will not be able to supply oxygen.... even in the rain of shells, precious oxygen burns in an instant.

"Damn......! Hellfire, shoot through his people!" Fire Shoot "!

Although the Demon King unleashes a long range of sorcery to do something about that iron rain, it's hard to hit enemies who are beyond the horizon and can't be seen.

"Can't you still... The human army is cowardly! I didn't expect you to fight without showing up!

Hel Arche says so, but her sight showed another enemy.

But she was just left behind because she didn't see it as a threat.

It is an iron dragon flying over the sky, an "airplane" as Akira put it, and if you put it in more detail, an "airborne observer".

And I still don't know the Demon King, but in long-range shooting by artillery, the presence of those who "observe" and "modify" the landing error is the most important and threatening.

In fact, the desk above did its important work from the gap between nitrous and black smoke and some cloudy weather.

"This is Merlin 03, confirming the proximity bullet to the demon king and the target. Determine that it falls within the formula error range. The target appears to have stopped and deployed defensive magic. No need to fix it, they started firing potency shots. '

"Corberg08. Copy that. I'll do my job. Full fire will take place in 120 seconds. Watch out for stray bullets'

"Merlin 03, roger."

Hel Arche does not realize that the aircraft above has dodged.

I naturally didn't even know that would mean a sign that "heavy rain" would shake in a few minutes.

"- Shit!"

After the wind-cut noise, the roar.

The earth explodes, black smoke rises, and in a semi-productive surgical ceremony, energy is liberated powerful enough to be broken through.

"Are you all right?!?"

"This is Zintzer Squad. Several of my men have been wounded, but no dead!

"No Kreutzel squad is dead either. Two wounded!

"Okay. Everybody, don't push it!

But having said that, they can't do anything under this circumstance.

The best way to do this is to approach the enemy suddenly and slap the artillery squad, but it made it difficult at a time when the human army had already started firing at full force.

Plus the fatigue of the last few days blunts their judgment.

"Your Majesty, it won't last long. Step back!"

"But we still have allies!

In the brains of Hel Arche and SS members were received the waves of thought emitted by the Heyvar position guards.

He said, "There are many wounded, and we have not been able to retreat".

"But Your Majesty. If there is anything in His Majesty, there is no ex or child!

"Demon King, if anything runs first, it involves the morale of your allies. Besides, you think I'm gonna die?

"Sometimes just in case!

The debate between SS and the Demon King continues, but it also did not stop the rain of 107mm shells weighing 17 kg in total, and they could not move a single step.

It didn't stop raining when Hell Arche fought back, and what he got was the pure fact that it was "no use fighting back".

The human army, on the other hand, had not been damaged against the SS with Demon King's fortitude compared to the amount of ammunition consumed.

But there is no one to be pessimistic about it.

"This is Merlin 15. Take over the observation mission. The goal is still motionless. No need to fix it '

"Corberg07, roger. Continue shooting '

An administrative conversation is exchanged between the observation team and the artillery.

Artillery fires, an observer observes, and the Below Demon King SS magically prevents it.

The intermittent pouring of shell rain succeeded in sealing SS movements, and the front remained glued for another three days.

But as it stands, as Akira puts it, the problem on the barracks, that is, the fuel used by the artillery squad for shells and observation planes, runs out.

I had to hit some hand before that, but that was the spindle of Operation Orchestra.

At this time, there was a different movement from the performance of the unstoppable artillery on the part of the human army.

Opposite the Hyvar position, the Frontline Command Post (CP) of a position built by the human army.

An officer there was meeting with the front-line commander for a report.

"First Special Vehicle Platoon 'Arthur', Ready"

"Good luck reporting. According to the observatory report, the target is currently suspended and has not suffered any noticeable damage. But it's already been three days since the gunfire was exchanged. The fatigue and stress of the enemy will be extreme."

It is a clear fact to say pale.

That is also the initial goal of the orchestra operation.

As a first step, an offensive due to time differences is carried out at a remote point, forcing the Demon King SS, an emergency deployment unit, to march long distances in a short period of time.

Then launch a massive offensive as a second stage.

Kill SS mobility with shooting by luxurious artillery to exhaust more enemies.

All for the sorrow of mankind: the Crusade of the Demon King.

And that was half successful.

Until the second stage it is carried out without problems.

Reinforcements of the Demon King's Army are also not allowed, and the defensemen at the Hyvar position are almost finished retreating, but SS cannot retreat and are exhausted.

"Finally,"

"That's right. There was a directive from the Command for the third phase of the 'Orchestra Operation' transition. It's your turn. Operation starts at 1400. For the survival and peace of all mankind, I wish you good luck."

"Ha."

Arthur Platoon has already completed the "necessary preparations" for the operation.

The same goes for the artillery squad in full force fire, ready. There were no holes in the carefully planned operation so far.

"Platoon pour! We're moving on to phase three of Operation Orchestra now! Everyone, check the gear you need! And just in case! Don't forget to get your mask and Pam ready!

"" "Roger!

The weather around the Hyvar position is cloudy with no good or bad weather, almost windless.

It was the best day of the operation.
