The surrounding D-particles gathered to form a large crescent-shaped boomerang, which flew toward Vritra's group. The D-particle boomerang, which cut through the atmosphere, hit the neck of Vritra, who was in the center.

　The D-particle boomerang's blade slammed into Vritra's scales, making a metallic sound, and as the serpent's scythe was about to leap backward, a spatial vibration wave extended radially from the boomerang, violently shaking the space where Vritra resides.

　The vibration wave shattered Vritra's cells into pieces. Not only that, the D-particle boomerang continued to release spatial vibration waves while spinning, and the torso of Vritra, which was nearby, was also reaped by the spatial vibration waves and disappeared.

　Vritra is hit by the D-particle boomerang, and its head itself disappears. The other Vritra's head also falls to the ground. Now there are only four left.

　Vritra and his friends were killed, and they are coming at me at great speed. Faster than expected, I hurriedly activated "Descrescent".

　A D-particle boomerang cut one Vritra in half. Three more remained, but they slowed their rushing speed. They were apparently cautious because one of their companions had been killed by a single blow.

　That was my chance. I released a quintuple-parallel activated "crash ball" against the three Vritras. Of the three, only one was hit, leaving a 50-centimeter-long hole in its torso, a fatal wound.

　Against the approaching Vritra, Elmore stepped forward. He intends to fight with Trishula . I didn't let Tamegoro participate in this battle, so it was just me and Elmore.

　One of them took the invitation and started fighting Elmore, so the remaining one and I started fighting. When Vritra opened its big mouth to attack me, I slammed a "crash ball" into its wide-open mouth.

　A spatial vibration wave went through Vritra's mouth and into my head. I jumped to the side as fast as I could. Vritra passed by me, spitting out blood.

　After confirming that Vritra is not dead, I throw my body up into the air with a quint catapult. At a position ten meters in the air, I activate the Seventh Glaive. I slam the blade into Vritra's torso to finish her off.

　When I landed on the ground using my "airbag," I watched Elmore's fight. Elmore was trying to thrust the tip of his trishula while dodging Vritra's attack at high speed.

I'll cover you."

　I shouted and activated the "Crash Ball" with a fivefold parallel activation. One of the leftmost of the five lined up D-particle vibration balls hit Vritra, shaving off her sturdy skin. Seeing this, Elmore leapt onto Vritra's back and stabbed Trishula into the injured area.

　The shockwave emitted from the Trishula seems to have topped Vritra.

Well done."

　I praised Elmore and Metis, then searched for the drops. Six red magic stones and Vritra's skin were found. With these, I could make armor for Tamegoro.

Let's go check the treasure chest."

'It would be nice if there was something in there that would help fund the establishment of Battalion.

　Me and Elmore enter Vritra's nest and approach the treasure chest.

I'll open it.

　I nodded silently as Metis, concerned about the trap, said. Elmore carefully opened the lid of the treasure chest. There seemed to be no traps.

　Inside the treasure chest were three things. One was a block of vermillion steel weighing about 30 kilograms, and the other was a gemstone called a chimera crystal. The other was a gemstone called a chimera crystal, which looked like blue, yellow, and pink flames dancing in the crystal and was about the same size as a five-carat diamond.

　And the last thing that remained was some kind of device. When I looked it up in the appraisal monocle, I found that it was a "D-particle fiber manufacturing device. However, there is a missing part in this device.

　Elmore lifted the D-particle fiber manufacturing device from the treasure chest and placed it on the ground.

'Wouldn't this missing piece incorporate a D-particle crystallizer?"

Oh, maybe."

　When I defeated Aqua Dragon, I got a "D-particle crystal device" as a drop, but I didn't know how to use it and left it unattended. I had planned to look it up when I had some free time, but I couldn't make time for that.

D-particle fiber manufacturing equipment. If you have thread, you can weave D-particle fabric. If such cloth exists, it can be given properties.

How much is the Chimera Crystal worth?

I heard it was very expensive, but I wonder how much it would be if it were as big as a five-carat diamond. I'll have to ask the Adventurers' Guild to find out.

　We decided to go back to the ground.

　Back on the ground, we go to the Adventurers' Guild. This adventurers' guild seems to be getting busier and busier. It seems that more adventurers have moved here since the A-level adventurers were released from the branch in this town.

　Maria, the receptionist, spotted me and approached me.

Dr. Grimm, I will contact the branch manager. Please wait."

　It seems that the branch manager is basically in charge of dealing with Class A adventurers. After a short wait, I headed to the branch manager's office. I entered the room and greeted the branch manager.

I'm just here today to report on the Narukami dungeon."

I know you don't understand this because you haven't been A level for very long, but A level is the representative of all adventurers," he said. Naturally, they are treated differently in the Adventurers' Guild.

　The Adventurers' Guild seems to value not only A-level adventurers but also C-level adventurers and above, who are allowed to dive in advanced dungeons.

　It is not that they do not value lesser adventurers, but they especially value those who can play a major role in advanced dungeons and help the adventurers' guild grow.

And good luck to the A-level adventurers in your country, because many of them care about how many places they rank in the World Adventurer Rankings."

　As for the ranking, I completely forgot about it. Well, I haven't done anything since I heard that I was in the bottom two hundred and sixty-seventh place, so I guess I'm still at the bottom of the list.

　I reported what happened in the eighth layer of the Narukami dungeon.

"Oh, so you got the vermillion steel and chimera crystals."

　He reported on Zhu steel and chimera crystals that may be sold. However, we did not report the D-particle fiber manufacturing device. We are not obliged to report the contents of the treasure chest, so there is no problem.

Are you planning to sell Zhu Steel?"

I'm a living magician, so I don't really need weapons made of red steel or anything like that. I'm a living wizard, so I don't really need vermillion steel weapons or anything like that."

I'd never give it up. If I were a magical wizard, I would never give it up."

And I got about thirty kilos of it."

　The branch manager was surprised at the quantity. The red steel can be obtained from treasure chests, but in most cases, it is in the form of ingots weighing about five kilograms.

　I asked about the value of the chimera crystal.

Chimera crystal is expensive because it is produced in small quantities. If we put it up for auction, a crystal this size could fetch as much as 100 million.

　I let out a triumphant yell in my mind. My face just can't stop grinning.

What about "What about Shu Steel? Do you know the market price?"

I guess so. One kilogram is about eight million. If you process it into a weapon, it will be more than five times as much.

　Hearing this, I was reluctant to sell it as ingot. He decided to find a blacksmith who could process the red steel and have it made into weapons.
