The reason why I wanted to make a dildo was simple.
It was the product that I wanted to sell en masse to the brothel. But this topic was far deeper than just that.
All the way back in the Skyladder sect, I learned about dual cultivation. And just like anyone could expect from someone born in the science and information era, I refused to believe that it was all about some kind of mystic connection.
'It has to be some kind of rule,' I thought as I continued to carve more and more runes into the straight monster's bone.
As I didn't understand the concept yet, I could only work on the physical aspect of the dildo.
The physical aspect being... the vibration.
I wasn't as arrogant and naive to believe that my dildo would be the first inanimate object that women of this world would insert in their holes for pleasure.
As much as this idea got popularized in the modern world by the porn videos and general relaxation of sexual standards, it was something too obvious not to exist before.
That's why, in order to have any shot at taking over the market, I had to bring out the one feature that turned a simple back-massager into the most popular sex tool of all time!
And soon, I managed to nail it!
Despite how complicated the runes that I used were, the idea behind the mechanism was pretty simple.
I would start by taking a relatively high-quality bone and turning it into the same enchanted thing that I used to advance my arcane weaponmaster skill by one level.
Once it could hold mana inside, I would suck it all dry out of the energy before adding more and more runes.
The entire vibration mechanism worked around three sets of runes.
Two of them would be a simple set aimed at storing the mana inside. The real magic would happen within the third set of runes, located right between the two previously mentioned sets.
'Let's call it an alternation device,' I thought to myself, taking quite a lot of pride in the design.
In this world where people took mana for something spiritual, I had no prior works to base my experiments on. In fact, the guide to the formations already felt like a cheat code all on its own.
'Actually, it feels as if it was written by someone from the earth rather from this world,' I thought, looking towards my pants where I kept my storage ring.
This was another puzzle that I would have to solve one day... But it wasn't the time for that yet.
'The more I learn about this world and how it works, the more questions without an answer I get,' I thought grimly, only to shake those thoughts out of my head and focus on the topic at hand.
The alternating mechanism was pretty simple. Using some of the most basic logic, the mechanism would detect which of the two storages held more mana before making the mana flow from one to the other.
Did I mention that mana appeared to have some sort of physical qualities?
It was the aspect of the spiritual force that I used to make sure the process wouldn't just equalize right away. And thanks to this quality, by the time the amount of energy in the storage would be the same, by the time the logic would detect it... the other storage would already receive more energy than it should!
In a sense, this was a flaw. But instead of lamenting over it and how it made me unable to make the earthy designs for vibrating devices, I simply made the best use of this flaw for my own purpose!
'Now then,' I thought after successfully making the bone vibrate in my hand, 'how the fuck am I supposed to make a male masturbator?'
This was the one thing that was really stumping me down. Even though I did... ekhem... possess a sleeve or two back in my popular days, I had no idea just how to replicate all the functions that it had.
'Maybe just add some vibrating massagers inside?' I thought, only to laugh the idea off.
As simple as it sounded, the second I attempted to imagine how it was supposed to be working...
I dropped the idea when the schematic in my head involved over a hundred small and complex elements.
'Damn, I didn't expect it would be that hard to even come up with the idea,' I thought.
For the next few moments, I attempted to come up with some kind of ingenious designs, each more complicated than the other.
And I didn't even start thinking about how the hell could I obtain a skin-like material!
And then it dawned upon me.
"I shouldn't let the knowledge from earth restrain me!" I nearly shouted.
Why come up with complex mechanical solutions to things that surely had a simple magical solution?
Too excited to think rationally, I reached to my pants and rubbed one out of my ring to pull the formation guide book. Then, instead of looking at the chapters, I scrolled through the pages to find the pages with basic formations.
A few minutes later, I found it. The chapter is filled with all sorts of formations with different uses and explanations behind the runes used.
Two minutes later, I nailed it.
'An air producing formation,' said one of its names, right above the 'air sucking' formation.
I quickly copied the designs of the runes and their purpose on one of the cheapest bones I had. As I was still far from being fluent in the local language, I did everything in my own language, one that this world has yet to see.
'With those, it should be manageable,' I thought before finally realizing what would be the greatest hurdle in the project.
'How the hell am I supposed to make a skin-like fabric?'
I could recall that on earth they would use some kind of special synthetics. But there was no way I could create something like this in this tech-free world!
