The items I showed to Miach and Naza were a press and cosmetics.
"This press... If Hephaestus or Goibniu saw it, they'd want to make a contract immediately..."
"A mechanical press with gears, cams, and flywheels, a hydraulic press that needs hydraulic cylinders, and a power hammer with a structure that repeatedly strikes with a hammer—I guarantee no blacksmith would refuse these three, right?"
"Certainly..."
It might have sounded a bit arrogant, but Miach nodded in agreement.
"More than that, these cosmetics... They could captivate not only goddesses but also female adventurers and even ordinary people...?"
"Cleanser, toner, essence, serum, and then lotion and sunscreen—there are many types on this side..."
"No... The more, the better for this side. Do you have any more?"
"Uh... I do, but these are types used during bathing, like bath bombs..."
"...What are they?"
"First, the simplest ones are scented soap, shampoo, conditioner and treatment to make hair softer and shinier, and finally scrub used to remove scalp dead skin and sebum?"
For some reason, Naza looked at me with an expression I couldn't understand.
"Uh... why that expression..."
"Why didn't you tell me about such good products sooner!!"
"...Huh?"
"This is clearly a product that would be a hit if made... If you had this, you should have told me earlier...!!"
I had actually made the recipes long ago, but since it was before making bath bombs, at that time, I didn't even have money to buy materials, let alone equipment, so I forgot about it, thinking I'd bring it out when the time came.
"Uh... it's because I didn't have the equipment to make it?"
"We can buy the equipment with the money earned so far..."
"Th-that's true..."
Well... it's a good thing I remembered it now, isn't it?
"...You forgot, didn't you?"
"..."
"I thought so..."
'This is a bit unfair...'
"Anyway, there are quite a few more besides these... Is this enough?"
"More than enough..."
"It's more than enough, to the point of being excessive."
After finishing the conversation, we each started preparing to execute our plans.

"What on earth is this! That girl!? Bell is mine!"
"Hey hey, Bell isn't anyone's property."
"Ugh... I know! I just wanted to say it!"
"Hmm, you're drunk."
"Ueeeeeeeeeh!! BellBellBellBell!! Please don't disappear in front of me!!"
"..."
"...Miach."
"Sorry for calling you both when you're busy. Hestia asked me to have a drink with her for the first time in a while."
"That's fine... but why are you having the drinking party at home of all places?"
"Ahaha... Nothing else tastes good to me anymore except the food you make."
"...So, what snack would you like?"
"I'd like some of the fried food you made before."
"Yes, order received."
Except for Hestia visiting in the middle to make drinking snacks and later, when she got completely drunk and passed out, I delivered her in the cart used to move large amounts of herbs to the abandoned church where Bell and Hestia live, we prepared without any major issues.
.

"It's still a prototype, but... it's complete!!"
"Hey... you finished making yours too...?"
After five whole days of working day and night, saving sleep, to make prototypes, Naza and I each made the items we aimed for.
"Now all that's left is to test if they work properly..."
The three types of presses I made and the various cosmetics Naza made—naturally, they weren't exactly the same as what I remembered, but that was due to improvements to fit this world, so now all that was left was to test if they worked properly and had no issues.
"But first... I'm going to sleep a bit..."
Naza suddenly got up from her seat and started staggering towards her room.
"...Huh? We just need to test them and we're done..."
When I expressed doubt about the current situation, Naza silently pointed outside.
"...Huh?"
When I turned my head, what I saw was a completely darkened sky with only the moon shining.
"You might be fine without sleep for about two days thanks to your skill... *yawn*... but I'm not..."
When I came to my senses and looked again, Naza had dark circles under her eyes.
"Hmm... then let's do the testing in the afternoon and rest for now."
"You don't seem like you're going to rest yet..."
"While making the press, I thought of an interesting weapon and made it. I'm going to go to the dungeon for a bit to test it."
"Okay... have fun..."
Naza, who always told me to be careful when going to the dungeon, said to have fun, so she must really be tired.
"...Shall I escort you to your room?"
"Hmm...? No, it's fine, so go ahead..."
Just in case, I pretended to pack my things and checked if Naza properly entered her room, and only after confirming that Naza lay down on her bed did I relax and finish preparing to go to the dungeon.
"Now... I've packed enough bullets, potions, and the newly made weapon... Did I get everything?"
With that, I headed to the dungeon.
"First, starting with goblins... huh?"
"Fire Bolt!!"
"...Bell?"
"Fire Bol...t... huh?"
"...What are you doing?"
"K-Kai-san?! Why are you in the dungeon at this hour?"
"That's what I should be saying, you brat..."
I met Bell, who was running while frantically casting magic.
"...So, to summarize, when you updated your status today, you suddenly gained magic, and you couldn't resist wanting to use it, so you sneaked out without Hestia knowing and came to the dungeon at this late hour to try out the magic?"
"Uh... it feels a bit shortened, but that's right..."
'Did he already read Grimoire?'
I remembered that Bell hadn't met Lili that long ago, so for a moment, I wondered how he already learned magic.
'...Oh right, it's already been five days?'
Due to the Cognitive Shaping skill, whenever I made something, time flew by, so I even forgot that five days had passed.
"Um... so why are you here at this time, Kai-san..."
"Haven't you been coming to the shop every day lately to buy potions?"
"Ah, yes, but recently, I haven't seen Naza-san at the counter, only Miach?"
"Ah... now that I think about it, I didn't tell you... Lately, Naza-senpai and I have been busy making something each..."
"Huh... then, you came here to..."
"We finished, but it was late, so senpai went to sleep, and I wasn't sleepy, so I came to test the newly made weapon."
The moment I said I came to test the newly made weapon, Bell looked at my right hand and said.
"Is the new weapon that thing you're wearing that looks like a combination of a gauntlet and knuckles?"
"Right!"
"Ooh! So what's its name?"
"Power Fist!!"
It was a weapon that suddenly came to mind while making cylinders for the press, and of course, it didn't exist in reality; it was a weapon from a famous post-apocalyptic survival game.
'Anyway, this is a fantasy world, and there are substitutes that make things impossible in reality possible!'
In this world, there exists a thing called magic stones that replace Earth's electricity, and since there are already many items made using magic stones, it was possible to simplify some complex designs.
"So... when you hit anything, that cylinder? thing is pushed back, and when it's pushed back, it hits the magic stone attached at the very end, and at that moment, a small explosion occurs inside, delivering a huge impact in an instant?"
As a result, this weapon, which was only treated as romantic in games, was born, and now all that was left was to test it in实战.
"Oh... you understood that complex thing pretty well? Right, so now I need to test how long it can be used in实战... huh?"
Just then, a goblin appeared ahead.
"...Gyaa?"
"Ha, haha!!"
The moment I discovered the goblin, I charged towards it and swung my right hand wearing the Power Fist with all my might.
"Die!!"
'Thud!!'
"Gya, gye?!"
'Splat!!?'
With the small explosion sound of the Power Fist, the goblin's head burst like a balloon, and blood and brain matter scattered in the direction I threw my punch.
"...With this much power, it should work up to the 6th floor?"
And I was momentarily stunned by the stronger-than-expected power.
"I thought it was just an辅助 tool from the explanation, but it's a weapon with incredible power!!?"
Bell was just as surprised as I was.
"...Bell."
"Yes?"
After confirming the weapon's power, I put my hand on Bell's shoulder.
"Let's... pick up the tempo a bit?!"
"Let's go!!"
Bell smiled broadly and started frantically casting magic at monsters.
"Fire Bolt!!"
"Ahahahaha!!!"
And so, Bell and I went down the dungeon, slaughtering monsters like mad.
"I'll take the last one! Fire Bol...t... huh...?"
"...Bell?"
For some reason, Bell suddenly lost consciousness and collapsed.
"Gyaaaak!!"
A goblin ran towards the fallen Bell, baring its sharp teeth, but
'Bang!!!'
Just before its teeth reached Bell, it was hit by the bullet I fired, and with a large hole in its chest and its magic stone shattered, it turned to dust and disappeared.
"Why did he collapse all of a sudden? His breathing is a bit slow and shallow, but regular, so it seems like he just fainted..."
While examining Bell, who had no significant injuries, not even small scratches, but suddenly fainted, I was puzzled.
"...Ah! Could this be that mind down?"
The conversation I had with Naza when she explained mind potions.
'Of course, when using magic, mana is consumed, and what quickly recovers the consumed mana is the mind potion I'm holding now...'
'What happens if you use up all your mana?'
'It's called mind down, where you lose consciousness and collapse with severe fatigue... Sometimes people with strong mental power endure with evil, but... usually, they just faint on the spot...'
Fortunately, I couldn't sense any other monsters nearby except goblins, but the dungeon is the dungeon, and you never know when new dangers might appear and attack Bell, so I decided to stand guard, dealing with nearby monsters until Bell regained consciousness.
"It's already been about five minutes, when is he going to wake up... By the way, I feel like I've seen this situation somewhere before?"
While dealing with goblins gathering upon hearing the gunshot, I felt that this situation was familiar for some reason, and just as I was lost in thought, the sound of human footsteps came from a bit away.
'Click!'
I reflexively took out my gun, aimed in the direction of the sound, and steadied my breathing.
'The footsteps seem to be human, and there are at least two people... Please don't be suspicious people.'
I waited tensely for a few seconds.
"...Huh?"
Two familiar faces appeared.
"Riveria and Ais?"
It was Lübearia in good condition and Ais, whose clothes were slightly torn as if she had been in a fierce fight.
"We came because we heard a loud noise... Do you come to the dungeon at this hour too?"
"Ah, what I was making was completed, so I came to test it a bit..."
I hurriedly hid the gun in my pocket and honestly answered Riveria's question, and at the same time, when I subtly shifted my gaze to Bell lying on the ground, the two's eyes naturally turned to Bell.
"This child is..."
"It's Bell Cranel, who was insulted at that tavern before. We happened to meet in the dungeon and were hunting together, but he suddenly collapsed, so I was keeping watch for a while."
"...Indeed, that boy Bete insulted. These symptoms are mind down. He probably used magic without thinking ahead."
I had somewhat expected it, but hearing it from Riveria, the current great mage, made me more relieved than when I diagnosed it.
"Hey... Riveria..."
"Yes?"
"I want to compensate this child..."
""...What?""
...At Ais's casual use of an expression that could be misunderstood, both Riveria and I were flustered.
"Rather than compensate, a different expression... Never mind."
Riveria held her forehead for a moment, then smiled gently like a mother of a child, approached Ais, and whispered softly.
"...Are you sure that's enough?"
"Ah, of course, and besides... no man would be unhappy if it's you, right?"
"...I don't really know."
"You don't need to know."
I didn't know what it was, but it seemed the conversation ended well with Ais doing something to Bell to "compensate" him.
"I'll go back first, so handle the rest yourself."
"Okay, thank you Riveria."
Since the situation passed by in an instant, I was flustered about what to do, but Riveria spoke to me first.
"I'm going to head up now, what about you?"
"Uh... I'll go up too..."
Accepting Riveria's offer, we started going up the dungeon together.
