I went through the process of auctioning off the chimera crystal at the Adventurer's Guild, leaving only two of the red magic stones I had obtained during today's search to be redeemed at the guild. The rest, I thought, I would use as a magic battery.

Speaking of which, did you hear about Mr. Saijo?"

No. What is wrong with Mr. Saijo?"

If you're not listening, that's okay."

　When you say so, I want to be sure. I found out from the branch manager. He told me that I was lucky to get to A level because of my luck.

　He seems to think that I was able to defeat Aqua Dragon because Akagi and his team did the damage, not because of my ability.

But after defeating six Vritras this time, I will have to change my mind, because it is difficult for even an A-level adventurer to defeat six tough Vritras solo. This will be a point in the World Adventurer Rankings."

　Saijo will have no choice but to admit my ability. If you still think that it was luck that got me to the A level, please tell me after you defeat a demon equivalent to six Vritras.

　The World Adventurer Ranking is based on the number of demons killed or new discoveries made that are stronger than specified, which are converted into points, and the overall points are used to determine the ranking.

　This is the first time I've earned points since I've been in the A level.

　As I left the branch manager's office and returned to the reception area, Saijo, whom I had mentioned, entered the guild.

'Gosh, I haven't seen you in a while Mr. Grimm, what have you been doing since you got your A-levels?

Today I went to the eighth level of the Narukami dungeon and fought and defeated six Vritras.

　Hearing this, the adventurers shouted 'Oh! Saijo looked unhappy.

Where on the eighth layer?"

　I explained the location and told them I had found a treasure chest in Vritra's lair. The adventurers wanted to know what was in it, so I told them.

It was a chimera crystal of about five carats.

"At about five carats, that would be ...... 100 million. Awesome."

I'm sure the chimera crystal wasn't the only thing in there," he said. It was indeed a treasure chest from an advanced dungeon."

This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.

　Instead of the Adventurers' Guild becoming more active, Saijo became more and more grumpy. It seems that he sees me as a rival, and he doesn't like my success. But wasn't my goal to become a Class A adventurer? I heard that he wanted the immutable bottle for that purpose.

It's amazing. That's Class A."

　Saijo praised him, his temples twitching. I wanted to warn him that if he pushed himself too hard, his blood pressure would rise and his blood vessels would burst, but I suppressed the thought that it would be the mature thing to do not to tell him.

Thank you. Saijo-san, please do your best."

　Saijo's eyes seemed to be lifting, but it must have been an illusion. I left the Adventurers' Guild and returned to the mansion.

Saijo-san was getting quite grumpy, is everything okay?"

　Metis raised his voice.

You must be Mr. Saijo. If you have time to talk behind my back, you can catch up with me with your achievements."

I think it's a very difficult thing to do. After all, Mr. Grimm is a wise man.

I didn't get my achievements because I'm a wise man. There are already a lot of magic developed by armored wizards and offensive wizards, so you just have to learn that magic, defeat the demons, and make a track record. I think it's advantageous not to have to develop new magic."

I don't think it's because they are wise that they are strong, because wise people don't always make the A level, but I think it's advantageous to be able to study the demons you are dealing with and develop magic to deal with them."

'Well, that might be an advantage. But that doesn't explain why people think I'm stronger because I'm a wise man."

I know Dr. Grimm puts in a lot of effort," he said. It's something that no one else can do.

　I am glad that there is one person who understands my efforts. It's just a little disappointing that one of them is Métis. I would have preferred a young woman if possible.

'Do you have any funny thoughts?'

'No, I'm not thinking about it. More importantly, what do you think of 'Descrescent'?"

I thought it was very powerful."

I think the power was great, but I think there is room for improvement in the movement at the moment of hitting the demon. But I think there is room for improvement in the movement at the moment it hits the demon."

　When the spinning D-particle boomerang hit Vritra, a spatial vibration wave was radiated after it pushed Vritra in. This is because the D-particle boomerang's blade was made to radiate spatial vibration waves after it bit into the demon.

　The reason is that the additional effect is exerted after it bites into the demon, as in "Cold Shot," but considering the nature of spatial vibration waves, we thought it would be better to improve it so that spatial vibration waves are radiated the moment they come into contact with the target.

　He started up the Sage system and began to improve "Descrescent". The timing of the spatial vibration wave's radiation was changed, and in addition, the rotational force of the D-particle boomerang was increased at the moment of contact with the target.

Why do you want to increase the rotational force?"

Do the Métis know about mouse fireworks?"

　Métis said she didn't know what it was, so I explained that it was a type of firework that emits sparks around it while spinning. I explained that it would be more powerful if I modified the D-particle boomerang to emit spatial vibration waves while spinning at high speed, like a mouse firework.

　The "Blow Up Glaive" magic, which had been a concern, was also made to be learned at magic level 13, with the exception of the characteristic.

　At that time, Nagase, a Class A adventurer, was exploring the eighth level of the Narukami dungeon.

"Phew, I finally found it."

　After spending some time searching through the jungle, they found a staircase descending to the ninth level behind the waterfall.

　After descending the stairs and reaching the ninth level, Nagase noticed a grassy field spread out before him and a town in the distance.

I hope that town isn't abandoned. An undead town in the middle of a fresh meadow is a mismatch."

　Nagase approaches the town with caution. Then, he saw a resident of the town. The inhabitant of the town was a minotaur. He was about three meters tall, equipped with armor, and carried a long-handled weapon like a halberd in his hand.

　Nagase thought it was a town, but this place looks like a fortress. Several minotaurs with weapons are patrolling the perimeter of the fortress.

"Is this the Minotaur's fortress? From the looks of it, there must be a higher species of minotaur."

　The higher species of minotaurs are demons such as the Minotaur Commander, Minotaur General, Minotaur Lord, etc.

　Higher-ranking species may be equipped with magical weapons, making them formidable enemies even for Class A adventurers. Nagase returned to the ground after checking the size of the fortress and the number of minotaurs.
