Just after going back in time and experimenting with 'tracing'.

　The second battle between Nagase and the Silver Ogre was also escaped by using an escape ball. I asked Branch Chief Kondo about the situation.

We fought using 'Hermes Speed,' which increases your speed tenfold, but it seems we didn't win the fight within the two-minute time limit."

Is there a third time?"

We're going to have to rethink our strategy, and that's going to take some time.

It's tough."

　The Kondo branch manager looked at me with a stern look on his face.

You talk about it like it's someone else's business, but Grim, you're a Class A adventurer, too, and you're up for the challenge."

The branch manager also said that only A-class magic-armor wizards can defeat the silver ogre. The branch manager also said that only A-class magic-armor wizards can defeat the Silver Ogre."

　The branch manager lets out a sigh.

I said so, but I am also wondering if anyone would be willing to take down the Silver Ogre. At times like this, adventurers who push themselves to challenge the Silver Ogre come out, and they get seriously injured or die."

　It seems that such a thing has happened in the past, and a B-grade magical wizard challenged the silver ogre and died.

Why can't we have a raid battle with only those wizards who can use that 'Hermes Speed'?"

　The branch manager becomes reluctant.

If you're prepared to let a couple of people die, that's one thing. But that is unacceptable. Besides, there is also the option of asking a magician with a higher ranking to do the job.

　If we ask another magician to do it, it will destroy Nagase's reputation. As a branch manager, he would not want to do this.

　　　◆◆◇◇◇◆◆◇◇◆◇◇◆◆◇◆◆◇◆◆◆

　I decided to wait for Nagase to defeat the Silver Ogre while I trained patiently. Then Ami was accepted to the same university as Amane and the others, and Taichi, Ami, and Shun graduated from the Magic Academy.

　Taichi will become a temporary teacher at the Magic Academy while continuing as an adventurer. I submitted an application for the establishment of Battalion after the renovation of the mansion and the completion of the underground training hall. I heard that I would receive permission in about a month.

　I had spent the last few dozen days training with the D-particle sensor and the "Gale Dance". I enjoyed the training itself because I could feel that I was getting stronger little by little.

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

　He is now able to fight high-speed battles using the "Ring of Vikaten," even when his speed is increased to seven times, which is almost eight times faster than the limit of the ring, and he is also able to use "super-speed vision," an ability that integrates information from the D-particle sensor and information from vision to create a visual image.

　I also practiced "Gale Dance" with Mitsuhashi Shihan every day and drilled the movements into my body. Thanks to this, I had bruises all over my body, but I gained confidence that I could definitely defeat the Red Ogre.

　Around this time, I was often told that 'the atmosphere has changed'. I was also told by the branch manager and Alisa and others, but I don't know how it changed.

　I was impatient with the lack of progress in the Narukami dungeon, but I was told that this kind of thing often happens in high-level dungeons. Sometimes it takes years to complete a dungeon, and sometimes it takes a long time to get a skilled person from far away to help.

　By the way, we did not defeat the shadow species of lintvurm. The black Lindtvurm is very wary and hides in the shadows when approached. We are in the process of figuring out how to defeat them.

　I did some more research on Lintvurm and found out that this small pterosaur had good eyes and ears. I knew from previous experience that Lindtvurm had good eyes, but I did not know that it also had good ears.

But how did you get away with it when you used the 'sign-off earring'?"

'That was because we were attacked by the red Lindtvurm.

　Hearing Metis' words, I remembered. When I tried to approach the black Lindtvurm equipped with the "Attention-Dissipating Earrings," I was interrupted by the red Lindtvurm.

　Even then, the black Lindtvurm got away from me, so I thought that the "sign-disappearing earrings" were ineffective.

　I head for the Narukami dungeon. I move from the transfer room on the first level to the transfer room on the tenth level and fly to the rocky area on the right side of the pyramid with the D-particle wing.

　This rocky mountain area is a lintvulm nest. Lindtvulms of various colors were nesting here. Red, green, blue, and golden lintvulums were conspicuous, but there were also black lintvulums among them.

　I landed and proceeded toward the lintwurm nest. I wore a camouflage poncho over my armor so that I could assimilate into the surrounding scenery and not be seen. In addition to this, I was also equipped with a pair of "presence-disrupting earrings.

　Cautiously approaching the lintvulm nest, I search for the black lintvulm. I find one. I check around and see several lintvulms of various colors nearby.

　I approached Lindtvurm and the others cautiously. This time, I was able to get as close as 50 meters without being noticed by the small flying dragons. However, if I got any closer, they would have noticed me.

　It needs to be finished off with a single shot. He activated "Death Crescent" and released a D-particle boomerang toward the black Lintwurm. The D-particle boomerang flew with tremendous speed, hitting the Lintwurms before they could escape and increasing its rotational speed while emitting spatial vibration waves.

　The vortex of spatial vibration waves, like demons of destruction, engulfed several lintwurms and choked them to death. Not only that, but it also carved a huge wound in the rock pile itself.

The "Descrescent" is clearly magic for big game hunting."

　Metis shouted when he saw that they had killed several lintwurms, small flying dragons, by chopping up part of a rocky hill.

But this guy is the fastest."

　After collecting magic stones using the "Magic Stone," I was able to recover three Red Magic Stones and one Shadow Magic Stone . After that, I continued hunting and obtained three shadow magic stones and 40 kilograms of shadow clay.

　Having obtained the desired shadow magic stone, I headed for the pyramid's mid-boss room. I wanted to check on the Silver Ogre.

　Then, the "Iron Oath" team, cursed in the Minotaur Tomb in the ninth layer, was arguing in front of the middle boss room.

Do you think we can defeat the Silver Ogre?"

　A man who seemed to be the leader of the "Iron Oath" team asked the other three.

You never know unless you try."

But even Mr. Nagase, a class A student, couldn't beat him."

I fought it solo," he said. If you jump into a room and attack all at once, you can defeat even the Silver Ogre.

　I heard such voices. Thinking they are idiots, I turn my back to them to leave before I get involved. At that moment, the adventurer who had said he could defeat the Silver Ogre starts saying strange things.

Why don't you attack them from outside the room?"

You idiot, you learned at the Academy of Magic that it's forbidden."

You never know unless you try."

　Hearing this, I turned around. At that moment, the adventurer launched an attack spell at the silver ogre.

Stop!"

　I screamed, but it was too late. Some kind of magic shot into the middle boss room. The next moment, everyone, including me, was thrown into the middle boss room.
