Bring Elmore out of the shadows and survey the interior of the temple with him.

"Mr. Grimm, here's another text with a sacramental script."

　The text was carved on a part of the wall of the temple. I took a picture and then read the text. It was inscribed that the "Gray Weaver," a follower of the spider god Atrak-Nakua, had been sealed.

　When I tell Metis what the text says, he remains silent and begins to think.

The Spider God ...... is there such a myth?"

　I tilted my head. Could it have something to do with the arachne we had defeated in that cave?

Atrak-Nakua is a fictional god from the Cthulhu Mythos.

The dungeon takes in all of that stuff?"

　I let out a sigh. The Cthulhu Mythos is a creation myth created by Lovecraft and other writers. I thought of the Red Ogre and the Blue Ogre when I thought of ...... that might eventually incorporate Japanese folktales and come up with a Red Ogre or a Blue Ogre.

　No, an ogre is a western demon. It would be something different from the red or blue ogre. What is the gray weaver anyway?　Is he a spider monster because he is a follower of the spider god?

Is that all?"

No, there's a sort of warning at the end."

What's it all about?"

Do not draw the sword that seals the evil god, for he who does so will receive the wages of death. So it is inscribed.

　Elmore and I looked at "Gram: The Divine Sword" as if it were a plague god.

This would definitely be a mythical magical weapon."

Shall I pull it out?"

Anyone who would pull it out after being warned so much is either very confident or an idiot."

'Does the last warning mean that if I pull out the sacred sword Gram, the sealed evil god will come out and kill me?'

Probably, yes."

So it's a monster that even a sword-gram can't defeat."

　That being said, I thought that the divine sword gram might be a single A or double A, not a mythical major.

I'll have to report this to the Adventurers' Guild and make sure they know not to pull out this sword."

The story has been taken without consent; if you see it on Amazon, report the incident.

'But what kind of monster is this follower of the evil god that even the divine sword Gram can't defeat?

The only way to find out for sure is to pull out your sword, but if you ...... do something stupid like that, you'll be scolded by Branch Chief Kondo."

　I decided to return to the surface. After returning to the surface, I went to the Adventurers' Guild and reported to the branch manager.

I see...you mean to say that the Spider God's household is sealed up in Kumayo Mountain?"

'Yes, sir. Please issue a warning letter from the guild so that no one touches that sword."

　Branch Chief Kondo agreed. When the warning letter was issued, the adventurers who read it became excited about the topic of the divine sword Gram. Magic-armored wizards wanted the sacred sword Gram, but no one wanted to touch it for fear of the existence of the evil god that had sealed it away.

　Nagase and Montaner, who were A-class adventurers, went only to look around, and then turned back.

　While the adventurers were talking about the divine sword Gram, I was resuming the development of the hover cannon, which I had interrupted.

　Shiroki steel with and properties necessary to create a shield to protect the gunner from the blast and shock wave, Sogin with , , and necessary to make the whole float, plus a propulsion device and brake, are fabricated and given to the factory.

　The propulsion system and brakes were fabricated with the help of Amane. The hover cannon was assembled at the factory with the ammunition feeder and sighting device completed.

　The hover cannon became a two-seater vehicle. The gunner, who operated the loading device, sighting device, and magnetic generating barrel, sat in the front, and the operator, who controlled the hover cannon, sat in the rear.

　I would be the gunner because I had to operate the magnetically generated barrel, and Metis, who controls Elmore, would be the pilot. To test the hover cannon, we went to the second level of the Narukami dungeon.

　I decide to target a rock pile and test fire the hover cannon. I activated the "projection barrel" and connected the magnetic force generating barrel to the hover cannon.

'It seems to be all right.'

　The connection to the magnetizing barrel is precisely made. Thanks to this, there is not much error in the sighting. However, some minor adjustments were necessary.

　Me and Elmore get on the hover cannon and I use the sighting device to aim at a large pile of rocks. I pull the trigger and the feeder pushes the shell into the magnetically generated barrel.

　At that moment, a cannonball ejected at supersonic speed from the tip of the magnetically generated barrel. The recoil was absorbed by the shock-absorbing device built into the connection. This works by using the characteristics of .

　When only the magnetic generating barrel was used, the barrel itself absorbed the recoil, but it could not absorb it completely, which was a drawback that caused the sights to be off.

　I fired five shells in a row. Each time a shell hit a rock pile and exploded, the shape of the mountain changed.

'I can only say that the power is tremendous. Couldn't we blow the evil gods away with this?'

I don't know. We don't know what kind of monster it is."

　　　◆◆◇◇◇◆◆◇◇◆◇◆◇◆◆◇◆◆◇◆◆

　Rumors of a divine swordgram in the thirteenth layer of the Narukami dungeon spread around the world more than the adventurers of Shibushi City had thought possible. Then a team of C-level adventurers from overseas heard the rumor and came on an expedition to Shibugami City.

Gnawan, are you really going to pull out the divine sword Gram?"

　Teammate Hartanto, an attack wizard, checks with team leader Gunawan, a magic-armor wizard.

It's no wonder. You can easily get mythic-grade magical weapons."

　Another teammate, Shahab, a magic-armor wizard, looks unconvinced.

It won't be easy. You're going to be fighting an evil god that's been sealed away."

　Gunawan grins.

"I have a countermeasure for that. If we don't try to fight the evil gods, and instead think of countermeasures based on the premise that we will escape from the beginning, we should be able to escape."

If there is such an easy countermeasure to come up with, why don't the Japanese pull out their sacred sword grams?"

The Japanese are cowards. They are afraid of evil gods."

　Gunawan said, making fun of the Japanese.

　Gunawan and his group arrived in Shibushi City, reported to the Adventurers' Guild that they would be working in the Narukami Dungeon, and spent the night at a hotel. They then headed for Narukami Dungeon the next day.
