After a pleasant rest day with Alisa, I returned to the tree dungeon. When I got to the tenth level desert area, I finished the rest of my search and descended to the twelfth level.

　We did not find much in the grassland area of the twelfth layer, and went to the ruin area of the thirteenth layer. The toughest monsters here were blue ogre zombies, but since we did not explore the area in much detail, there may be other tough demons lurking there.

　As I pulled Elmore out of the shadows and entered the ruined city, a skeleton knight approached me. He pulled out his sacred sword, Gram, and held it ready as he stared at the bone-only demon.

　The skeleton knight approached with his shield and spear at the ready. He paid off the thrusting spear with his sacred sword Gram and jumped into the pocket, and then he used his circular shield to perform a shield bash. The shield bash is an attack method in which the shield is slammed into the enemy.

　He swung the sacred sword Gram down on the protruding circular shield. The circular shield was split in half, and even the hand holding the shield was cut in half.

　At the same time that the circular shield fell to the ground by the wrist, the blade of the divine sword Gram sliced open the skeleton knight's skull. The divine sword Gram could not be protected by an ordinary shield. Well, it is a divine sword that can cut even rocks, so it is not unreasonable.

'Well done. If you are dealing with the undead, I think the light sword Clau Solas is the way to go, but why the divine sword Gram?'

'I don't know how to use the sacred sword Gram, so I'm thinking of trying it out while I'm using it.'

But it's dangerous to try it with a demon.

I know, but I couldn't figure it out when I tried it against trees and rocks. But I think I could figure something out if I was dealing with demons."

　Métis, who knows my instincts are not to be fooled in these situations, did not object. But he did put a condition that Elmore escort me.

　As for the sacred sword Gram, I tried cutting trees and rocks while pouring magic power into it, but I don't know what effect it would have.

　As we proceeded down the main street of the abandoned city, we came to what looked like a plaza. There we see a dead fountain and broken statues. No, some statues are not broken. At the edge of the square, a giant mammoth-like statue remained intact.

The story has been illicitly taken; should you find it on Amazon, report the infringement.

Isn't it strange that that statue is intact when everything else is broken?"

That being said, ...... no way ......."

　The moment I said that, what I thought was a statue began to move.

　It was a mammoth, four meters high to the shoulders, a super-heavy mammoth. With each step, the earth shook and the cobblestones of the plaza broke.

　I thought it would move slowly because of its large size, but it came at me with footsteps echoing with zushin, zushin at considerable speed. I reflexively slashed his leg with my sacred sword, Gram, and then jumped back.

　Elmore thrusts the Zekkai spear into the demon's belly. The demon staggered under the attack of the Zekkai spear. Considering the difference in weight, this is impossible. It seems that the Zekkai spear has some kind of special power.

　The demon swings its long fangs around and tries to fling Elmore away. Elmore quickly dodged the attack and leapt backward. It was a great jump of twelve meters.

　I quickly took out my goggles for demon identification and confirmed the identity of the demon. It was a "bronze mammoth," and its weak point was said to be the core between its eyes.

　I put away my demon appraisal goggles, pour magic power into my sacred sword grams, and charge at the bronze mammoth. The bronze mammoth shakes its head and tries to reap me with its long tusks.

　He stepped in and slashed away at the sturdy-looking fangs. The slashed tusks fall to the cobblestones of the plaza, making a noisy noise. I leap into the pocket and slash repeatedly at the bronze mammoth's belly and legs.

　Then, use the quint catapult to escape backward. For short distance movement, "Catapult" is faster than "Flash Move". It is better to use "Catapult" depending on the distance to move.

　Inform Metis about the Bronze Mammoth.

He's moving a little strange.

You've slowed down."

　Upon closer inspection, the bronze mammoth was walking heavily with its feet up. Moreover, the broken cobblestone pavement was wider with each step. Could it be that the bronze mammoth is getting heavier?

'Could it be that the power of the divine sword Gram is to manipulate gravity?'

Let's give it a try."

What are you going to do?"

I try to imagine the bronze mammoth's head being crushed as I slash at it."

　Metis didn't seem to understand what it meant.

Why did you do that?"

"I want to see if I can specify the area of effect of the sword-gram by its image."

　So far, the attacks with the divine sword Gram seem to be having an effect on the entire body of the bronze mammoth. If, hypothetically, the effect could be concentrated in one place, I thought, it would be much more powerful.

　I wanted to move for the bronze mammoth's head, so I activated "Flash Move". A flashleaf formed by D-particles wrapped around my body and moved over the bronze mammoth's head.

　With the image of its head becoming so heavy that it crushes, he pours magic power into the raised sacred sword gram and swings it down.

　I felt the blade of the sacred sword Gram bite into the metal head and felt some power release from the blade. I jump off the bronze mammoth's head.

　Immediately thereafter, a sickening metallic sound came from the bronze mammoth. It was a creaking sound, and when I turned to look, I saw that the bronze mammoth's head had begun to crush.

　Finally, the metal head bobbed and crushed, and the bronze mammoth collapsed and disappeared.

'It looks like you made it.

Yeah, it's kind of an incredible effect."

There's a drop."

　I look at the area where the bronze mammoth fell. Something I had never seen before was left on the ground. It looked like liquid in a green translucent glass bottle.

　When I took out the appraisal monocle and examined it, it was labeled "High Metal Liquid. This is a liquid metal that hardens when D particles are added. Moreover, it is said that the strength when hardened is comparable to that of vermillion steel.

I think this could be useful for something. Let's study it later. There's something else down there."

　Elmore picks up what looks like a leather bag to check its contents.

It is a jewel. At the current market price, it would be about 300 million yen.
