The first power leveling is over, and we're currently on a break. Oh yeah, while we have the chance, let's give that weapon to Jin.

Currently, I'm flowing my magic into orichalcum and creating a new metal that is harder than orichalcum and has a higher magical conductivity through "material conversion," but it still seems to take a long time to complete. I've experimented with various materials and found that when using "material conversion," it's easy to convert to lower-grade materials, but the higher the grade of the material, the more magic is required and the longer it takes to convert. The metal I want to create is something that is considerably higher than orichalcum.

So, as an experiment, I tried to see what would happen if I advanced adamantite by one grade. Adamantite is one level lower in hardness than orichalcum and has two levels lower magical conductivity. Fortunately, there were two adamantite swords, so I flowed magic into both to the limit, formed an image based on orichalcum as a reference for comparison, and imagined adding space-time magic to the sword as a trial, and activated "material conversion." Three days later, the sword was completed. The original adamantite sword was blackish in color, but the new sword was completely jet black. The name was also changed from "Adamantite" to "Lonsdaleite." When I shook it, it was easier to hold and a sword that matched my image was completed. As a bonus, I found out that it was possible to add space-time magic to "Lonsdaleite." This was very exciting. It was an unexpected harvest that I could add space-time magic even though I did it mostly on a whim.

As a result of the experiment, the jet-black sword became:

My personal "Lonsdaleite Sword"

Name: Shiden

Addition: Space-time magic "Meteor Rain"

Jin's personal "Lonsdaleite Sword"

Name: Murakumo

Addition: Space-time magic "Gravity Breath" (Superior version of spatial magic "Gravity")

In this way, it became a considerably powerful weapon.

Jin and Rikka, along with Finn and Iris, are taking a break and enjoying the afterglow of lunch.

"Jin, there's something I want to give you."

"To me?"

"Yes, you're good at martial arts, but from now on, you'll need more than just martial arts. So I'm giving you this sword."

"Are you giving me this amazing sword? But what material is it made of? It's not adamantite or orichalcum, yet it has the same hardness as orichalcum."

"The material of the sword is Lonsdaleite, which is one grade advanced from adamantite using 'material conversion.' It's a special metal that has space-time magic 'Gravity Breath' added to it."

"What! Can I really have such an amazing sword?"

"Yes, the name of that sword is Murakumo. Make sure to train your swordsmanship and spatial magic in this dungeon. It might be a good idea to spar with Rikka."

"Thank you, Sasha-sama. I will devote myself to living up to the name of this sword."

"Aww, Jin, that's so cool!"

"Rikka has claws, right? The hardness of those claws is on the same level as Orichalcum, although they cannot be enchanted with magic. They should be more than enough to handle your techniques. In addition, those claws are only usable by Rikka, and I have also enhanced your body to prevent the claws from injuring you internally. Your current strength level is the same as Jin's. (Since they are stored, only Rikka can use them)"

"What! Did you say that I'm as strong as Jin? Oh, I'm so happy!"

Phew, it seems that Rikka is also satisfied.

"Oh, by the way, once we reach the entrance to the sixth floor, I'll call the two of you back."

"Sasha-sama, are you going to challenge the Zombie House?"

"Jin, no, it's exactly as you said. There are two reasons for this: it's a major shortcut, and there's a clear bonus for clearing it."

"But I heard that it's quite difficult, are you sure you'll be okay?"

"Hehe, certainly, encountering the unknown is high difficulty for people in this world. But from my perspective, it's a bit easier since I've already experienced it. However, there are still some concerns. If it becomes too much, we can find a statue of a goddess and retire."

"Understood. Until then, I'll release my stress by sparring with Rikka."

With Finn and Iris and Rikka's consent, the break was over.

________________________________________

Currently on the fourth floor, the floor type is a forest. Perhaps due to getting used to the first floor, they were able to clear the second and third floors without any problems. They were also able to respond firmly to surprise attacks from the Evil tribe. Therefore, on this floor, Finn and Iris are exploring the stairs to the fifth floor by themselves.

Now, I'm alone and acting alone. In my case, if I make even a little noise outside,

"Ahhhhhhh!" thud

Here it is. You either scream and faint or run away as fast as you can. They won't let me fight. Well, my power leveling is supposed to be the clear reward for the zombie house, so it's fine for now. I want to try using my newly made sword, [Purple Lightning], since my Mithril sword's durability is about to run out. Hmm, there are three evil creatures ahead. The Orga Knight, Adamant Wolf, and Black Viper, perfect for a test slash. Other adventurers like Finn and Iris are not in the direction of the evil creatures. Let's try using a finishing move. I've never used one myself, so I want to see how much power it can unleash. However, I can't go all out, so I'll just use the minimum amount of magic needed to activate the finishing move.

I activated "Meteor Rain" on Purple Lightning, compressed the energy to the limit, and aimed it at the space where the evil creatures were located, flying towards the ceiling. Then, I sealed off the entire space within 100 meters of the evil creatures to prevent any sound or impact from escaping. And finally, the finishing move was activated.

------- As a result, everything, including the evil creatures and the forest, vanished except for the ground and ceiling. However, the sealed-off area pierced through the ceiling and floor and turned into magma, making it impossible to get close. If I hadn't sealed off the space, this dungeon itself would have been destroyed. Once again, I've gone beyond what humans can do and entered the realm of gods. I need to learn to control my power better. If I don't, I might end up destroying Spheretalia. There is also a fight with the mastermind. By then, I'm sure I'll be able to use it with ease. Let's brace ourselves and continue the journey.

We gathered evil creatures for power leveling and met up with Finn and Iris. After leveling up, we left the 4th floor and moved on to the 5th floor, which was also a forest.

"Master, did something happen? You seem a bit tense."

"Do you understand? I used a finishing move on three evil creatures on the 4th floor. Thanks to the space magic that I used to seal off the area, there was no damage around them, but the area within about 100 meters of the evil creatures was scorched. If I calculate the power in the sealed space, the dungeon would have been destroyed if I hadn't used space magic."

"Master, what are you doing!"

"Onee-sama, it's too dangerous!"

"I had no choice. I wanted to know my current strength because I haven't really fought with my full strength before. I never thought that a finishing move with minimum power would be capable of destroying the dungeon. From now on..."

"Master, please never do that again without telling us."

"That's right. Please at least inform us beforehand."

Oh well, they're so worried.

"Okay, I'll do that. But you two are back to normal as always. You adapt to the environment so quickly."

"It's all because of you, Master (Sister)!!"

Did I do something wrong?

"Anyway, there are fewer traps in this forest, but the evil race's skill usage is much better compared to the surface. Since we're on the 1-5 floors, the zombie house from the 6th floor will be challenging to conquer. Can you both handle it?"

"Y-Yes, we're fine. We're getting used to the forest type. So far, we haven't fallen into any traps, and we can handle this-----Ah~~~! Hiiii~~~!"

Oh no, they were careless and fell into a simple trap. The trap is straightforward. When someone steps on the area where the trap is set, a robust vine made by the dungeon system wraps around the person's feet and lifts them 10 meters into the air, flipping their head and feet upside down and hanging them from a tree.

"You fell into it because you were careless. If you were wearing a skirt, you'd be in trouble. Look, the evil race is targeting you, Finn."

"Huh? Are we going to fight in this situation?"

While hanging from the tree, a chameleon owl is targeting Finn's throat with a dive. Finn avoids the owl's claws, but she can't counterattack while hanging from the tree.

"Ugh, it's so annoying. Then I'll use 'Wind Rifle.'"

Wow, that's a good idea. She aimed at the chameleon owl's dive with "Wind Rifle," a wind magic spell, and shot it down. She then cut the vine and defeated the chameleon owl.

"Finn, you've become able to handle it calmly."

"Why are you both so calm about this?"

"Oh, you're used to the forest, right?"

"For some reason, Finn doesn't seem to be in danger."

"Well, it's a good thing I'm wearing shorts. If I were wearing a skirt, I wouldn't be able to get married."

Well, that's true.

"Iris should be careful of that trap."

"Why? What do you mean?"

Fin looked at Iris and explained to her, "Imagine Iris right now, hanging like Finn was, and Ariel witnessing it. Do you understand what I mean?"

After a while, Iris turned bright red and said, "No! I absolutely don't want to show that state to Ariel!"

"That's why both of us need to be careful," Fin replied.

"Why is our master not worried? She doesn't seem to be cautious of traps," Iris asked.

"In my case, I constantly circulate magic throughout my body, so I can immediately tell where traps are located. Even when I'm sleeping, I can deal with assassins who appear through teleportation. If you both circulate magic throughout your body all the time, you can do the same. It may be tiring at first, but gradually, magic will accumulate in all your body tissues, and you will be able to instantly discern the opponent's movements and traps," I explained.

"So, does that mean that you are constantly circulating magic, even when you are awake or asleep?" Iris asked.

"Of course. This is a different world. We never know when, where, or who might attack us. We can only trust ourselves. Even if you have your favorite boy by your side, you should not let your guard down. Evil tribes or thieves might suddenly appear and attack us in the city," I explained.

"I see, master, but that means we cannot relax," Iris replied.

"I am relaxed. I am still relaxed even now," I replied.

"Why can you relax with that mindset? If everything around you is an enemy, I would not be able to calm down," Iris asked.

"Well, my martial arts teacher taught me that since I was a child. It seems that my teacher had experienced several disasters and lost both parents and friends at that time. So, my teacher taught us diligently to prevent us from experiencing the same thing. At first, I was exhausted, but I gradually got used to it, and now I can relax while naturally observing my surroundings," I explained.

"Your teacher was amazing. Thanks to that teacher, you are here now, master," Iris said.

"Master, I will train myself to circulate magic naturally like you do," Iris added.

Fin and Iris had no trouble dealing with B-rank enemies even on the fifth floor, thanks to power leveling. They arrived at the staircase leading to the sixth floor without getting caught in any traps. They did power leveling on this floor as well, but their level increase had become more difficult.

Fin's current level is 30, and Iris's level is 28. Fin's strength has grown up to Class B, while Iris's magical power is already at Class A. At this point, the divine protection is working at its maximum, so we should be able to fight through the Zombie House, the next level we're about to challenge.

"When we pass through here, we will be on the sixth floor. Next up is the Zombie House."

As we descended, we saw a statue of a goddess and two large doors. In front of the doors, there was a sign that read:

"[The left door leads to the normal floor, and the right door leads to the Zombie House. There are currently 20 challengers in the Zombie House. The use of magic is prohibited until you escape.]"

"Onee-sama, are we really going to challenge the Zombie House?"

"Yes, it will be a good experience for the two of us, and there is a clear reward as well. It will save us the trouble of power leveling."

"But, Master, the use of magic is prohibited. What should we do?"

"Don't worry. Iris, equip that short sword of yours. The use of magic on both enemies and allies is forbidden, but the enchantment of weapons is not prohibited. Your Mithril short sword is embedded with a holy attribute gem called Aquamarine, which can deal great damage to zombies. Fin's Mithril claws are the same."

It was already 6 pm, and that was enough exploring for today. Since magic is prohibited in the Zombie House, we will have to camp there. We have prepared a bento box for the Zombie House, but since the two of them are already tired, we will stop here for today.

"That's enough exploring for today. It's already 6 pm. Since magic is prohibited in the Zombie House and we won't be able to rest, let's call Jin and Rikka back for now."

When Jin and Rikka were summoned back, Iris asked a question.

"Hey, Onee-sama? You didn't make a reservation at an inn, did you? Where are we going to stay?"

Hahaha, you're very observant. Ever since I became a evil god, I've been secretly using time-space magic to create an accommodation facility in another dimension. The rooms are like traditional Japanese inns, with a large bath and all necessary equipment prepared.

"I have prepared an accommodation facility in another dimension for times like this. We'll move there now and take a rest."

As I cast the time-space magic, a door appeared on the dungeon wall.

"That door leads to the accommodation facility."

"Sasha-sama, normally, it's impossible to travel to another dimension. You would need an enormous amount of magical power (evil power) to do it. So how are you able to do it so easily?"

"If its you, master, then anything goes, right?"

"Most things can be done by my onee-sama, you know."

"I want to eat dinner quickly."

"Is that really okay with you guys?"

Jin can be a good straight man (tsukkomi). Also, I can't do everything, you know.
