I’ve Been Reincarnated as a Tentacle Slime~ I Want to Live a Comfortable, Secure Life and Do Whatever I Want~ - Chapter 40

[Slime 2 POV]

Is the 11F supposed to be desert-themed? It’s hard to move because the ground is covered in sand. The floor is filled with 10 cm of sand, and for a person, it would probably reach their ankles. My older brother is reading the sign next to the white gate to gather information.

“It seems this is a fire-attribute floor from here on. Let’s apply water enchantment when we fight.”

“Yes, I understand. Even just this makes it worth coming here, doesn’t it?”

Sure enough, coming to 11F was the correct decision. I started to make a smug face—

“Actually, you could get the same information from the sign on the black gate on the 10th floor, but it was my mistake for not noticing.”

—but I didn’t. That’s right, it wasn’t just my older brother who neglected to gather information from the lower floor. Gathering information before battle is important. I am equally guilty for neglecting it.

“Big brother, big sister, there’s no point in feeling down. If you failed, just make up for it.”

Slime 4 offers encouraging words. That’s right, you can cancel out a mistake with a greater success.

“You’re absolutely right. Let’s pull ourselves together and look for monsters.”

My older brother gives us instructions, and we search for monsters around the gate. If it weren’t so complicated, we could find them immediately with sound waves… How troublesome. While doing that, I find a monster.

“We can consider what kind of monster it is after striking it. One way or another, it’s an enemy we must take down.”

A red lizard-type monster, its attack methods are probably its mouth, tail, and maybe some magic. The places to aim for are the upper part or the sides. As for weapons… it doesn’t seem to have any particular resistances, so a spear should be fine.

I cast a water wall spell in front of the lizard, cutting off its line of sight. While using sonar to track the lizard, I extended tentacles imbued with water around it. Just as I was about to attack, I saw flames erupt from its mouth, seen through the water wall. However, the flames could not break through the wall and merely warmed the water.

“At that speed, if the water wall hadn’t been there, the flames would have reached me. But since they didn’t, it can’t be helped. I’m going in!”

I aimed for the moment the lizard hesitated when its flames failed and stabbed it with my spear. The lizard jumped backward, but adjusting the path of the tentacles was enough. The water-element spear pierced it, and it died.

“Now then, I wonder if there’s anything to gain from this?”

I devoured the lizard, hoping a skill would manifest. The skill that appeared was [Oil Generation]. It seems I can refine flammable oil using magic… but what would I use it for?

I transformed into lizard form and used [Oil Generation], a mist of oil formed in my mouth. That’s it, with this, if I use [Fire Magic].

From my mouth, a stream of flames erupted, reaching several meters in front of me.

“I understand now. If I combine it with [Fire Magic], I could make things like Molotovs, flamethrowers, or even bombs depending on how I use it!”

I went back to my siblings and shared the information I had learned.

“This is amazing! If we combine it with fire magic and make it explode, creating Monster Houses will become easy! Let’s hunt one for everyone right away!”

In a rare display of excitement, my older brother was fervently looking for monsters.

Once we’d hunted enough lizards for everyone, we moved on to constructing the Monster House. I don’t like how much this feels like work.

“This time, there’s something I want to try, so let me handle it. You guys can do whatever you like.”

“Understood! I’ll go explore the surroundings a bit!”

What a kind brother! My younger sister and I joyfully went off to explore the 11F.

“Big sister, is it okay to go this far ahead?”

Slime 4 asked me with a worried look.

“It’s fine. Didn’t big brother say we could do as we pleased?”

Honestly, we probably shouldn’t, but as long as we don’t overdo it, it’s fine. At that moment—

KABOOOOOMMMMM!!!!!!!

A massive explosion sound came from the direction of the white gate.

“I’m worried about big brother! Let’s go back!”

“Yes! Big sister.”

Having transformed into our wolf forms, we rushed back to the gate, and found big brother covered in dust.

“Big brother! Are you okay?!”

I cast [Healing Magic] on my big brother. But he didn’t seem injured, so there was no change.

“Thank you. And I’m sorry. I got a bit carried away.”

Behind my apologizing big brother, I can see the unfinished Monster House. When I peek inside, a mountain of rubble has formed.

“Ah, so this is what making a Monster House is like. But do you think we can properly create one 50*20 meters this way?”

“It’s fine. By adjusting the amount of oil and the placement of the water wall, we can make a small-scale explosion. Also, if we carve out too much, we can just fill it in with dirt.”

“Isn’t your safety a concern, big brother?”

“I’m making sure to be cautious. If I bend the fireball like this, I should be able to ignite it from the corridor. If I shoot from far away, the impact will be minimal.”

I thought you were more of the cautious type, but you’re actually doing pretty extreme things…

“If that’s the case, it’s fine. But if you had just said something earlier…”

“I’m sorry for the inconvenience. I just really wanted to try it right away. It might be noisy again, but once it quiets down, that will mean it’s finished, so please return then.”

Big brother laughed, “Ahahaha…” as if to cover it up, and returned to the Monster House.

“Since big brother is enjoying himself so much, don’t you think we should enjoy ourselves too?”

“That’s right. Let’s keep moving forward!”

After getting Slime 4’s agreement, we resumed our dungeon exploration.

However, since the explosion sound faded in less than an hour, we had no choice but to reluctantly return before we could finish the dungeon…

Afterward, we brought the lizard back to floor 1 and spent the night making the Monster Houses until morning. Big brother taught me the explosion method, and it was actually quite fun! Watching the fire pillars rise in the corridors was so fun! I wonder if this could be used for hunting as well? Let’s try it tomorrow!

◆◆◆◆◆◆◆

The next morning, during the hunt, I suggested to my big brother that we could use it for hunting as well.

“If the explosion isn’t too strong, it might be useful. After all, it would be troublesome if the prey turned into charcoal, and destroying the Monster House would defeat the purpose, wouldn’t it?”

Indeed, there is a risk of destroying the Monster House. In that case,

“Would it be possible to use the explosion sound to impair the prey’s hearing and sense of balance?”

“That might be a good idea. Let’s give it a try since we’re here.”

Since we planned to use bats for today’s combat training, we conducted the experiment starting from the 4th floor.

As a result, it had no effect on magical creatures or underwater monsters… but it worked on wolves and lizards. They were all unconscious, making it easy to hunt them.

Afterward, Slime 3 and 4 gave combat training to my younger siblings, and while we were making the Monster House, Father returned.

◆◆◆◆◆◆◆

“Welcome home, Father. How did everything go?”

“Aah, there are 10 thieves remaining. I confirmed the hideout’s location from above as well. That’s not the issue, though…”

Father-sama appears to be finding it difficult to say something.

“No matter what, we will all assist you.”

“I see… We might have 13 to 26 new children. I want to deal with the bandits before they are born… So, the time limit is only about 5 days.”

I’m not sure why he wants to deal with the bandits before they’re born, but I’m happy that we’ll have more siblings.

“Congratulations, Father. Leave the education of our new siblings to us. And about the 5-day time limit… If they are not given sufficient nutrition like we were, I believe they won’t be born for about a month…”

“Oh, that’s true! I didn’t think of that. In that case, it looks like you can make sure your preparations are complete.”

Ah, you were worried about us, weren’t you? Indeed, the young siblings will likely be just about ready in 5 days, but with a week, they’ll definitely be strong enough to fight.

“You were worried about us? I’m so happy!”

“This time it was my mistake. I didn’t want to cause you any trouble.”

Father-sama’s tentacles gently stroked our heads. While savoring the happiness, we reported our accomplishments to him.

“10F and 11F turned out like that, huh? And a new Monster House construction method and combat strategy too. Well done! I can trust you with the floors beyond 11F as well! So then—do you have any food for me?”

“Yes! We’ve already built Monster Houses on 10F and 11F for your meals, Father. The hunting is done, so this way, please.”

Elder brother guided Father-sama to the place where his prey was stored. After eating, Father observed how the Monster House was built, tried the method himself, and returned to the village.

“Oh right. I’ve brought a souvenir for the four of you.”

Father-sama gave us four birds that looked like hawks.

“With these, your range of movement should increase, right? I figured they’d help in taking down the bandits.”

“Father! Thank you so much! I swear I’ll use this power to be of service!”

“Father-sama! I’m so happy! With these, we can easily transport our younger siblings too!”

Someday, I want to earn enough trust to be taken along with you.
