Basement Dungeon ~Poor Siblings become the Strongest and Enjoying Exploration~

On August 1st, ten dungeons appeared all over Japan.

　The phenomenon was happening all over the world, and the world was plunged into chaos.

　However, it was only temporary, and now a year has passed since then, every country has stabilized, and they are being controlled by the military, opened to private individuals, or used to the disposal of garbage by taking advantage of the regular phenomenon of things vanishing inside the dungeon after a period of time has passed.

　In addition, dungeons have been used in various ways. Notably, they are being used for the disposal of dangerous substances such as radioactive materials.

　At first, there were many things we didn’t know about dungeons, but as the days went by, we learned more and more. However, each country decided that there was still insufficient information, and finally last month, more than a dozen countries that are exploring the dungeons gathered to have exchange information. Then the meeting was held.

　Although they don’t say how far their own country’s exploration has progressed, you can get a general idea by looking at what’s on the market.

　Currently, the United States is at the top of the list, followed by Japan and China. Therefore, this conference has become more about getting information from the US.

　In addition, the ranking of natural skills that were done in Japan was well received and will be done in other countries as well.

　It seems that the United States has gained some understanding of how dungeons work after the discovery of one of the American participants with an S-class skill.

　Among other things, he was able to tell them something that is safe to teach to other countries.

　That dungeons have a system and clear rules. This includes exploring with more than four people, and that those who ignore the rules will not be given the benefits of the dungeon.

　In other words, an explorer who enters a dungeon with more than five people for the first time will be considered to be in a party of five before gaining the first skill, and will not even be able to gain the skill, which is a reward from the dungeon.

　Also, dungeons have a system of Hate, and if you continue to hunt certain monsters, the Hate will gradually accumulate and cause unique monsters and stampedes.

　If you violate the rules of the dungeon, the Hate will build up at an abnormal rate, causing a large number of unique monsters and stampedes to occur.

　In many parts of the world, the day a dungeon was created, civilians and military personnel have infiltrated and were completely annihilated, for example, and this was thought to be the effect of this.

　Some parties ignoring the rules appeared in the dungeon, which would have resulted in several stampedes and unique monsters.

　They were quickly swallowed up by the hordes of monsters since they couldn’t shoot even if they raised their guns immediately, and they didn’t even have the proficiency and skills to fight with their batons.

　Also, dungeon bosses and unique monsters have a will. Some of them can think as much as a human, while others have intelligence equivalent to that of a highly intelligent animal.

　However, the fact that they have wills means that they are unpredictable, and unique monsters can even move through the levels, which is why they are said to have been, “released from the Dungeon”.

　The meeting went well, and each country was able to gain the knowledge necessary for dungeon exploration.

　The story goes back to Japan. About two weeks after the siblings defeated the Dullahan-like Gan Ceann that day, they successfully defeated the Minotaur and arrived at the Forest.

　This was their first encounter with the Japanese Rimdobmur. However, the only thing that was passed down to the public was that there was a dragon, so it’s unclear if it’s exactly a Rimdobmur, but looking at the dungeons so far, it’s safe to assume that all dungeons have a similar structure.

　And the term “The Strongest Five” was coined to refer to the top five parties, a term created during the title/alias commotion with the strongest explorers.

　Of these five strong parties, the four parties other than the Hero Party also succeeded in defeating the Minotaur one after another.

　Just two weeks ago, there were reports that ordinary explorers had also defeated a Minotaur.

　Japan is constantly getting stronger and stronger, the market is getting richer, and the top explorers and those who have made a fortune are earning over a billion yen a month.

　The dungeon market in Japan is getting more and more exciting. However, it is a pity that they are not a stock company and you cannot make money through stocks. If it were a stock company, the stock price would be rising rapidly.

　The Hero Party that came to the Tokyo Dungeon at that time has returned to Hokkaido and is continuing their exploration.

　And my sister and I,

“Congratulations!” (Haru)

“Finally, I can dive into the dungeon. We have to save money again because we have to pay for food.” (Kei)

　We are now in the hospital. I’m not sure what to do, but I’m sure I’ll be able to do it.

　But that doesn’t mean I can let her dive into the dungeon alone, so we’ve both been taking a break for almost three months.

　We’ve had a lot of time on our hands these past three months.

　Ever since the dungeon appeared in the Kizaki house, we’ve been spending our days hiding in the dungeon. It’s no wonder we’ve been bored since we suddenly can’t spend such days in the dungeon anymore.

　Fortunately, my bones hadn’t been broken too badly, so my recovery was quick. The cast is off, but I’m not allowed to play sports.

　So what should we do with all this spare time? Fortunately, we had a little bit of money, not a lot, but a little bit, that we made from the auction.

　If we can’t dive into the dungeon at this point, why don’t we just train?

　Even though my bone has a hairline fracture, my body is sturdy and I have a high status.

　In other words, if I recover to the point where I have a cast, it won’t get any worse unless I am seriously hit with a weapon.

　But once we’re in the dungeon, I don’t know what will happen to it due to the recoil when I slash the enemy.

　That’s why we went to a swordsmanship class for about a month.

　The course was held four times a week, and we were taught the basics of various techniques, from footwork to sword strikes.

　Our status and daily combat had improved our kinetic vision considerably.

　We were able to see the movements of the instructor and move our bodies as if we were tracing them.

　Since we fight in dungeons on a daily basis, our adaptability is well tested.

　After a month in the dojo, I think we’ve become a bit stronger.

　Our posture is no longer shaky when wielding weapons, and our movement has improved in terms of speed and fluidity of gait.

　I thought that being taught would be better than just doing it randomly based on my own experience.

　And so today, my arm is completely healed. I guess it’s a pity that the x-rays cost a bit of money.

　After leaving the hospital, we went straight home, but the time was too limited to go straight into the dungeon. So we spent some time taking care of our equipment, which we hadn’t used for a long time, and checking the news.

　I hadn’t been watching the news much lately, as I had been concentrating on practicing my sword fighting in the dojo, which was coming to an end.

“OK, maintenance finished.” (Haru)

　Haru seemed to have already finished and was tapping away at the computer on the table beside her.

“Oh, what?　Oh, my God. Brother, look at this, look at this.” (Haru)

　Haru must have seen some news or an incident in the dungeon because she pulled my arm and dragged me to the computer.

“What, wow, seriously?!” (Kei)

　The article displayed there was far beyond my imagination.

“America Confirmed Defeat of 16th Level Forest Boss, Rimdobmur!”

　Speaking of Rimdobmur, it was the one we had been unable to defeat.

　With a Power of 1050, he drove us to the point of being incapacitated with just its roar.

　Compared to that time, my level has risen by about 20, but I still don’t feel like we can beat him. My current level is about 70, so my Fighting Potential is about 210.

　I think it’s strange that Rimdobmur is three times more powerful than Gan Ceann in the first place.

　 So the party that defeated Rimdobmur in America must be incredibly strong compared to us.

“We have to do our best too.” (Kei)

“Yeah. Start exploring again from tomorrow.” (Haru)

　They hadn’t read the article carefully because they thought they understood the content just from the title
