On Earth, would you know what the oldest weapon in human history is?

The answer is' Biological Chemical Weapon '.

The oldest biological and chemical weapon (BCW) on record is about the sixth century BC, when Assyrians (present in the Middle East today) seemed to have poured the venom of strangulation into enemy wells during the war.

Incidentally, the poison of Wheat Nuclear Disease is a similar ingredient to LSD.

And in modern times, during World War I, chemistry developed around the end of the nineteenth century.

During World War I, the Germans sprayed hundreds of tons of chlorine gas. The coalition went up to about 20,000 addicts and dead combined.

Thereafter, the coalition side also uses chlorine gas and a fierce gas battle is waged.

And after letting out a large number of dead and addicted people, in 1925, the Geneva Convention banned biological and chemical weapons.

However, in preparation for the battle to come, countries continued to develop biochemical weapons (BCW).

And after World War II, biochemical weapons (BCW) become so much spoken of at the same time as nuclear weapons.

But for humanitarian reasons, postwar biological and chemical weapons (BCW) became critical, and the Biological Weapons Ban Treaty was signed multilaterally in 1972.

The rapid evolution of nuclear weapons, the rise of anti-war ideologies & humanism, and instability as weapons - and finally the signing of the Biological Weapons Ban Treaty - have ended their role as instruments of Biochemical Weapons (BCW) inter-state war and have been buried away.

However, there is still a threat of biochemical weapons (BCW).

It is only called "the nuclear weapons of the poor" and may be used in terrorism, etc.

Because from them, there is no need to uphold international conventions.

Biochemical Weapons (BCW), such a 'nuclear weapon of the poor' - it is created by witchcraft and ravages race in this interracial world by unknown substances and potencies that even modern people do not know about.

"Huh!

"Oops! Hobo!"

"Ha, help - huh!?

The first person to complain of clear symptoms was a general soldier fighting on the front line.

They destroy black balls because they think they're moving their enemies' non-creatures. Each time he was inhaling the black smoke that was flooding him.

Symptoms begin with nosebleeds, bleeding, fever, vomiting, confusion and gradual difficulty breathing.

You can't fight decently in that state, and you have to destroy black balls in order to defeat your enemies. For this reason, the attack takes its life, and the hand of the attack is dull and vice versa, and the front line is ravaged by the collapsed Demon King Army.

The magicians are still the best compared to the soldiers in general.

If you find that black smoke is poison, you can cure yourself with detoxification magic. But for that matter, I won't be able to support you on the battlefield. And the magicians had to defend themselves, so they had to do their best, and abandon the ordinary soldiers who could not use magic.

Worst of all, black smoke was slow acting.

Thanks to this, the symptoms began to appear after enough black smoke had gone to the racial coalition, and I was delayed in realizing it.

Of course, Racis Dance, chief of the Imperial Sorcery Knights, is no exception.

Severe vomiting, the smell of iron spreading across your mouth - it also makes you spicy standing offended by black smoke. He rushes to do the antidote magic on himself.

"Erase the footsteps of death that corrode the living. Poison, leave.

But I couldn't do anything more.

(This is not just poison smoke...... witchcraft is jammed!?

There are usually several ways to interfere with sorcerer's sorcery.

● Apply an anti-magic collar.

● Sleep, paralyze, or deprive consciousness.

● Interfering with chanting and not letting them use magic.

- Etc.

But this black smoke doesn't inhibit witchcraft by interfering with paralysis, drowsiness, etc.

Taste the feeling of being sealed with magic as if you could twitch an anti-magic collar.

Even in the long magician life of Laesis, I did not know that there existed a poison that gave such symptoms.

Above all, I did not imagine, such as using poison for the battlefield in this way.

Of course he and the Imperial Sorcery Knights have also done a lot of fighting against poisonous demons.

However, if poison is used on the battlefield, it is likely that damage will be done not only to the enemy, but also to the allies, significantly damaging their reputation and pride. Therefore, no one had committed such inhumane acts.

Yet this time, the Demon King unifies his army in an abiotic way, nullifying the poison.

We deliberately prepared fewer personnel than the racial coalition, making them glad to fight and destroy the balls.

As a result, the damage caused by the racial coalition becomes immense.

(There's only a retreat... but are they going to let us escape safely?

As it stands, the racial coalition collapses into an unexpected attack by poison.

Defeat the incoming enemy and more poisonous smoke will spread and be damaged. For that reason, everyone was hesitant to attack.

Further retreat is not just an escape.

If we don't stay disciplined and fall back in an orderly fashion, we will be pursued and vice versa, spreading the damage.

Also general soldiers falling due to poisonous smoke damage. There is also the option of abandoning the body if it is dead, but what should we do about those who have breath but are unable to move due to poison?

If you abandon it and retreat, morale will fall to such an extent that you will never be able to rebuild it again.

But if you don't retreat, you can't attack like this, you're completely poisoned, and you're killed.

I don't want to be the last to be prickled with both the dead alive.

"This... demon king's army. Yes!

"William!?

Even though Zagsonia Imperial Sorcerer Knights Deputy Commander, Sorcerer A Minus, and William McNael are poisoned, they storm as they bleed out of their mouths behind healing.

I don't mind destroying the balls and getting black smoke from the demons that flock, breaking and pushing.

Aikent stands behind the Demon King's Army.

Apparently William is aiming for a one-shot reversal by ignoring the demons of the Demon King's Army and defeating him as commander with the only creature.

I don't mind if I get poisoned and start sealing my magic.

"Stupid mane. Driven by merit!

Racis tongues his emotions uncommonly and openly on the table against William for such a reckless assault.

But it's too late.

William leads through a herd of demons and reaches Eikent with black smoke all over his body.

"The hand of the demon king! William McNael, Deputy Head of the Zagsonia Empire Sorcery Knights, can get that neck!

…………

William summons the rest of his magic powers to create the Great Sword of Magic.

Aikent also stood with his hands clenched with the sword he was carrying on his back.

"Saiya!"

Mood flashing!

William waves down the Great Sword from the Great Upper Stage - but Eikent holds that blow back by a wall of black magic that emanated from his surroundings, not his own sword.

That's the same thing that Demon King Legrottarier used.

William had heard the story, but the first defensive wall he saw.

Tighten the bloody mouth tightly and gaze.

"What's up! That sword is a decoration! Wield your sword with dignity!

…………

But there's no response to Eikent's anger either.

"Gaaaaaaaaaa!"

William screams like a beast, waving his great sword with all-out power and magic.

But all of that was inhibited and prevented by Eikent's black wall of magic.

William in complete condition would also have been able to forcefully break through this wall of magic.

But there is no magic and strength left for him to use it.

He is feeling worse than the average soldier who was fighting on the front line because he was forced to defeat the demons and showered his entire body with black smoke.

It's not strange to lose consciousness and fall if you are.

There's only one thing moving him.

"I can't lose! I can't lose! Even for the Empress Yumilia!

To make my beloved Empress Yumilia smile again.

Just for that matter he waves his sword.

But there is a situation that cannot be transcended by mental power alone.

William's magic, his health comes to the bottom.

The body, which was moving only by mental strength, stopped beyond a certain line.

To him like that, Aikent pierces his abdomen with the great sword he was holding in his hands like a task.

"Guuuuuuuuuuu..."

He bleeds from his mouth, and the great sword created by magic also spreads mist.

William falls to the ground without the art of exchange.

A shadow overlapping your body.

I can only see underfoot, but definitely in Aikent.

He approached to stab himself with a stop.

"Yu, Empress Yumilia......"

Abyss of death.

Horse running lights don't flow.

Just occupy the chest. It was the appearance of a loved one.

A new shadow overlaps William's body like that.

Aikent feels the crisis for the first time and takes a distance from William with a foot justice that looks hasty.

At the next moment, the wall covers up his sight.

"Ha ha ha ha! That's good! That's good! I'm unscrupulous for my beloved! Don't look over there. Barbarian courage is the privilege of the young! I don't hate you!

The walls that covered my sight gave me a delightful laugh and spoke.

William squeezes his strength and pokes his arm, waking up his squishy upper body.

If you look closely, that's not a wall.

No, in a way, it's not even a very sturdy wall of meat.

Already the opponent had undressed his upper body.

Thick chest plates, biceps, abs, etc. are cracked, and the muscles of the feet are revealed as if they were floating and stretching out as you can see from the garment.

The skin was black and a muscle wall stood with blonde hair all-back.

Apparently, this mass of muscle has been interrupting from above between William and Eikent.

I thought he had come down and I didn't know if I could say... something was flying in the sky.

In William's common sense, no bird-like feathers have grown on the airship.

Furthermore, only on the left side of the ship is something like a cylinder popping up.

It makes me asymmetrical and strangely uncomfortable because of it.

The muscle mastery standing in front of you meets William's gaze.

The mass of muscles smiled and affirmed.

"It's just a shame...... we don't have enough muscle! Young man, we need to build more muscle! With muscle, you can handle most things! Ha, ha, ha, ha!

After a frequent laugh, he tells William to deepen his grin as he turns his gaze toward Eikent.

"Then I'll have plenty of muscle shaking for the first time in a long time!

Thus Dan Gate Blood, Demonic Race Sorcerer Class A, entered the War of the Race Coalition Vs Demon King Army!
