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

“I’m home.” (Haru)

　Haru walks in front of me and opens the shabby door of our house.

　This shabby-looking door is quite strong, as it is processed using [Alchemy] with items from the dungeon. However, it should not be made too strong, because if it is made too secure, it could be blown away by the dungeon’s special characteristics.

　It is said that before the Dungeon Dam was opened to the public, they made a very strong door and kept it unlocked so that it would not be blown away by the dungeon. If that’s the case, then this house should be just like that, and the lock has not been reinforced in any way.

　It was the locks of a long-abandoned house in the countryside. It will probably break just by kicking it by someone with an unenhanced physical strength.

　The fact that it had never been blown off by the dungeon before proved that it was not a problem.

　The sky was already starting to get dark, and it would be better not to dive into the dungeon again, considering our supper and fatigue.

　Entering the house, I closed the lock, which was only for appearance, and took off my gear.

　Even if we make money, it’s still not enough considering the possibility of not making any money in the future.

　Who knows when our information will be leaked and when our home dungeon will become unusable? No one can predict that. If we were found out, we might end up with a criminal record.

　Both of us completed junior high school. If we were both junior high school graduates with criminal records, there would be no place that would hire us.

　Even in this day and age, it’s hard to get a job as a junior high school graduate. If that’s the case, it’s better to earn enough money while we’re still kids so that we can live without doing anything in the future.

　By the way, we are children, but what about taxes and other things? Well, it doesn’t matter if there are things that need to be paid and haven’t been paid yet, it’s the parents’ responsibility. Even though the old man had left the house without permission, he was still our guardian on paper.

　With this in mind, I finished tidying my gear and put it in the safe. I went out for a run, as usual, ate dinner, took a bath, and went to bed.

　By the way, this evening’s dinner was thinly sliced Minotaur beef stir-fried with yakiniku sauce. It was very tasty as usual. [T/N: Yakiniku is the equivalent of barbeques. The standard yakiniku sauce is made with soy sauce, mirin (sweet cooking wine), garlic, and sesame seeds/oil. It’s a mildly sweet and super savory sauce. ]

　And then.

“Okay, brother. Let’s go explore!” (Haru)

　The next day, we spent the morning gathering information on the dungeon drops that had been announced to the public, while pacifying Haru who had immediately said something like this upon waking up. I found something that still bothered me.

　It said that the appearance rate of rare drops and other items in Tokyo and other dungeons seemed to be unchanged.

　However, I don’t know exactly what the drop rate is because this is real life, not a game, and sometimes explorers say that the drops are better in this dungeon.

　Well, that’s it. It’s like when you’re in a pachinko parlor and this machine is more likely to hit the jackpot today. Or that it’s better not to play gacha games in a row. I guess it’s part of those baseless wish-fulfillment stories.

　Aside from that, the dungeons in this house lacked some of the drop items compared to other dungeons.

　It seems that the things that drop are generally divided into about four types. It’s not exactly what the government says it is, but what the internet has come to call it.

　A drop rate of more than 76 percent is called a normal drop.

　A drop rate between 31 percent and 75 percent is a semi-regular drop.

　Those with drop rates between 6 percent and 30 percent are quasi-rare drops.

　And anything below that is a rare drop.

　That’s all there is to it, generally speaking. However, there are some people who claim that there is actually a super rare drop below that.

　However, most people think that these super rare drops are usually unique monsters that look exactly the same as the ones listed above because the strength of the monster is not fixed and the monster is stronger than normal or looks slightly different.

　If you still call it a super rare drop, you’ll be treated like a chuunibyou.

　And aside from the super rare drops, there are other things that are called rare drops.

　The rare drops that have been revealed on the Internet have never appeared in our dungeon.

　Not all monsters have these rare drops, but some of them do. I’ve never seen it from those monsters either.

　For example, that rare rabbit. It’s a very high experience rabbit that you can only meet once in a while. They only have rare drops, and if you get a drop, you’ll get a magic tool. Well, the number of times we’ve seen a rare rabbit is barely two digits, so we can’t even verify it.

　While I was researching this, the morning ended and I made lunch while Haru badgered me telling me to, “hurry up”.

　I ate up my lunch with great speed, put on my gear, and finally dove into the dungeon.

“Okay, brother. Let’s get going. Go!” (Haru)

　While saying the same thing every morning, Haru, defeated a goblin that appeared in front of us with a single kick before heading to the transition area.

“The place we are going to go to is the Forest. We’ll do it right outside the cave so that we don’t have to worry about attracting Rimdobmur’s attention.” (Kei)

“Roger!” (Haru)

　 When I got confirmation while transitioning, Haru appeared at the destination and posed in a salute.

　My bad. It was while we were transitioning, so I hardly saw the joke.

“I’ll go first.” (Haru)

　As soon as she left the cave, Haru channeled her magic power into the ring. 893-san wrote that the Treasure Tool rings seem to contain the new Treasure Tool along with the previous Morning Star. You just have to think about what to use before letting your magical power flow through.

　Incidentally, after the new Treasure Tool was added, the ring’s name changed to “Touka’s Treasure Tool 2” and “Haruka’s Treasure Tool 2”. Apparently, the last number was a number that indicated how many Treasure Tools were inside.

　I saw something round and transparent floating in front of Haru. I know it’s the Treasure Tool, but it’s obviously not a tool. If I had to say.

“Liquid, magical power?” (Haru)

　Haru asks a question. The round thing floating in the air was just water floating in weightless space, and it looked like a magical power of a different quality from the magical power that I usually use. The size is about 30 cm in diameter. It’s not big at all.

“Haru, do you know what it is?” (Kei)

　I asked, thinking that the person who was using it would know better.

“Yeah. This liquid is probably unusual, but I think it’s magical. But you can touch it and see it with the naked eye.” (Haru)

　When Haru touches the liquid, it dents by that amount, slowly leaves Haru in a bouncing manner, and slowly returns to Haru.

“Although it doesn’t mix with my normal magical power, it can be finely moved using [Magic Manipulation].” (Haru)

　The liquid took a human form and waved at me. I almost waved back but stopped.

“Fufu. Let me use magic for the time being. [Collapse]” (Haru)

　Haru probably manipulated it. Then the liquid was splattered, it stuck to the nearest tree and was dyed black.

“That is. Is it okay to use Collapse?” (Kei)

　While [Fissure] ends immediately if left unattended, the [Fissure] she is now using will never end. It didn’t look like Haru was still manipulating the magical power.

“Huh” (Kei)

　Something happened that made me cry out.

　The tree, to which the liquid touched, began to wear out. The original [Collapse] has the power to shred the wood, but it does not have the power to swallow the shredded pieces.

“Oh.” (Haru)

　Haru shouted in admiration as she manipulated the liquid with her magic power, causing it to spread.

　The tree that was being sucked into the black liquid was not coming back out but was being sucked into the liquid that was in volume.

　In no time, the tree fully disappeared.

　Pan!

　With the sound of Haru’s hand-clapping, the liquid returned to its colorless state.

　The place that had been covered in black magic just now.

“I think it’s a little overkill.” (Kei)

“Well, it’s the way it is.” (Haru)

　The tree was gone, the ground was gouged, and there was nothing left of it.

“Yeah, it’s okay. Brother your next.” (Haru)

　Haru quickly erased the magic liquid and handed over the place to me.

“I feel like I’m gonna do badly after seeing Haru’s.” (Kei)

　While murmuring such nonsense, I head to the place where Haru had stood.

“So, Touka’s Second Treasure Tool!” (Kei)

　There is no part where I’d make a misstep, so I let my magical power pass through the ring while muttering firmly.

“Brother, it’s cool.” (Haru)

　Magical power was clinging to my body. Unlike Haru’s magical liquid, mine is almost invisible to the naked eye. I am just shining slightly? That’s about it. However, it seems that I, the person, who is covered can completely understand what it is.

“It’s like an armor.” (Kei)

　The magic power that clung to me was completely hardened, and when I tapped it, it made a thumping sound. Moreover,

“Is the weapon on your hand included in the effects?”

　When the sword is unsheathed, it seems that the sword is also strengthened by the magical power.

“Brother, is it sharp?” (Haru)

“Wait, I’ll give it a try.” (Kei)

　I walked up to a nearby tree and swung with all my might. The tree is cut in half with just that. Even to the place where the sword didn’t touch.

　If you try to cut the tree with your sword, it might cause the sword to become bent. The sword was swung just far enough to scratch the wood. And yet, the sword cut the tree in half.

“It looks like its reach has been increased. Maybe it’s a magic blade?” (Haru)

　I looked at the sword as I swung it and saw that there was no mark on the blade at all. On the contrary, there was not a trace of anything touching the sword. No, I guess literally nothing touched the sword. That’s how strong this magical power is. However.

“That’s it.”

　That’s it. It’s still good enough but compared to Haru’s liquid magic power. It’s just this. Well, there’s some luck involved, so it can’t be helped.

“Okay, Haru. we’ll hunt in the forest today.” (Kei)

“Yup.” (Haru)

　If that’s all there is to it, then let’s forget about it. We’re going to hunt again today.

　Well, we got Treasure Tools, though it wasn’t what we were aiming for. So what should we do next?

　Keeping that in the corner of my head, I readied my sword.
