Just when we were about to reseal the weakened seal of the Corrosive Earth, the person who damaged the seal appeared in front of us.......

''That's right, to the Zhang who I destroyed the seal of the Corrosive Earth, Gehohohohohohoho!

　The culprit, the demon, was dying for some reason.

"Why is a demon dying?

I'm sorry, humans. You may have come here to reapply the seal, but the seal is now in this state!

You're the one who looks like this.

　Liliera-san was right, the demon is already a worm's breath.
　His whole body has begun to twitch, and he's clearly affected by the impulse demon poison.
　If it wasn't for the strong body of the demoness, she would have died long ago.

　But why is the demon invaded by the impulse demon poisoning?
　In a previous life, witches were supposed to be able to block most poisons, but........no way?

"Be careful, Liliella-san.

Mr. Lex?

It's so poisonous that it could kill a demon. The being that's being sealed away could possibly be far more than I ever imagined.

　As if to affirm my fears, the demon smiles fiercely.

''Kukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukukun! Sealed in this land is this ghoho-ho-ho-ho-ho-ho-ho the Great Monster Venom Beat!　That poisonous insect that was said to easily fill an entire continent with poison!

"The Great Hexenbiest Venom Beat?　The legendary Venom Beat?

　I knew it. The demonic venom is a nasty and deadly poison that Venom Beat spreads around, then the one sealed in this land is none other than Venom Beat.
　But that's not what's so tricky.

　There's no way that Venom Beet's venom is going to be enough to invade a demon with that level of poison!
　In other words, the Venombeet sealed in this land is far more dangerous than the Venombeet I know, and is most likely a special individual born from mutation, or a biological weapon modified by ancient wizards.

　I see, that's why they took the means to seal it.
　It's a good thing that they were able to improve it in the previous life, but they were forced to seal it because they couldn't control it anymore, and that's what we hear every day.

I didn't think that just a crack in the seal would be enough to poison my body, but this would be enough to destroy the world of the humans!　After the humans have been destroyed by the Venom Beat poison, we'll take over this world, ghohooghoogho!

Um, can I ask you something?

　And Liliera-san raises her hand against the demon.

'Huh, what a human girl?　Do you want to hear how to beg for your life?

No, no, I mean, wouldn't you not be able to live with yourself if the world was invaded by a poisonous substance that even you, a demon, couldn't withstand?

....

....

....

Oh.

"You didn't think of that!

　Wait, wait, wait, wait! You really have no idea what you're doing, you witch!

"And I had no choice!　I didn't expect it to be so poisonous, gehoghohoho!

　The demon vomits blood and defends himself, but that's a bit too much of a haphazard plan, isn't it?

''Wouldn't it be better to give up and go home for a cure?

'Kukkukkuk, I'm sorry, but I've been spoon-fed by my friends that I'm out of control. And if I don't succeed in this plan, I have nowhere to return to!　Hence, we'll make this plan work at all costs!

　Hmmm, it looks like she's just been poisoned and desperate.

"It's hard to know what to do with an enemy...

'I understand what's going on over there, but that doesn't mean I can't wake up the Venom Beat.

　A special individual with a poison so deadly that the only way to deal with it is to seal it up, and it's hard to know how much damage it will cause when it wakes up.
　The damage that I explained to Liliela-san earlier could not be compared to the expected damage.

"I will defeat you and re-lock the seal!

Kukukukuk, I'm not so sure about that.

　However, the demon still had a fearless smile on his face.

''Not only is it two against one, but you're quite confident that you're dying from poison.

Huh, sure. But I told you. The seal is on the verge of collapse by my hand. That means that the seal will be completely destroyed at the slightest chance!　Haaaaah!

　Just when the demoness was about to unleash her full magical power and start a fight with us.

''This is enough for me.

　As the demon grinned and smiled, there was a cracking sound of the seal breaking from behind.

''Shit!''

　I didn't think the seal had weakened that much!

Warding!

I won't let you!

　Just as I was about to set up the wards in a hurry, the demon jumped at me.
　Are you planning to interfere with me, even if you are willing to die?

　I'm baffled by this unexpectedly undeterred action.
　It's easy to prevent the attack of a demon that's this weak.

　But that would delay the sealing of the deadly poison that poured out of the broken seal, even if only for a moment!
　If that happens, the people living in the neighborhood will fall victim to the Venom Beat's deadly poison!

I won't let you!

　It was then. As if to block the demon's path, Liliera-san stood in the way.

''Huh!''

　Liliera-san received the demon's attack and flung the demon away with her power.

''Gooooooooooooooooooooooooooooooooooooo!

　At the same time, my warding magic came in time.

'Grand Area Sanctuary!'

　The large scale ward that I triggered succeeds in completely trapping the deadly poison that was spewed out before it could spread to the surrounding area.

''But if you put up a warding, the poison will kill you this time!

　I know!　I immediately activate the antidote spell.

"High Ground Antidote!

　I deployed the highest level of antidote magic to immediately detoxify the deadly poison that was attacking us.
　The evil-colored poisonous wind that was coming from all directions was instantly purified into normal air.

''What, what?!

''Liliera-san, we're going to run upwards!

Okay, okay!

　We take refuge in the sky to escape the poisonous air.
　No matter how much we purify the poisonous air, as long as we don't deal with the source of the poison, the Venom Beat, we're still going to be weasels.

　At the same time as we evacuated to a high enough altitude, the small mountain on which the Temple of the Seal was built began to vibrate.

''What?''　Earthquake?

No, no. He's going to come back.

From above, I could clearly see the scene of it waking up.
Seven peaks radiating out from the oval shaped hill collapsed, revealing legs that could be mistaken for giant, thin, shiny metal pillars from within.
They pierced the ground and lifted the small mountain in the middle.

''The mountain ... is moving ...''

　The temple that was built on the mountain has completely collapsed, and the grass and dirt that had accumulated on the surface of the mountain spill over to reveal the things that had been sleeping underneath.
　Its color is black like darkness and its hard outer shell is almost impossible to cut, even with mithril.
　What is most striking is a single long horn that rises up to the heavens.

''That's the great demonic beast that was sealed in this land.......''

''Yes. The king of the most poisonous insect-monster beast, the transcendent of poison and miasma, also known as the Great Beetle King Venom Beat!
