Today, two chapters are updated simultaneously.
This is the second chapter.
The next day.
Once again, I began researching slimes right from the morning! But today’s theme isn’t just that—I also plan to conduct tests and experiments related to “elemental magic” and “mana” attributes.
First, for today’s experiment—or rather, the trigger that led me to form a hypothesis beforehand—I enlisted the help of one Sand Slime and one Mud Slime.
“Well, for the Mud Slime that’s understandable, but currently there’s only one evolved Sand Slime...”
I prepared sand and mud respectively so they could use their “assimilation skill,” which both species have learned. Changing the ground with elemental magic makes this easy. Once prepared, I had them actually use their assimilation skills.
Then,
“...Just as I thought.”
The two slimes approached the sand and mud, and they began to disappear as if melting away. Eventually, their forms completely vanished, but the two slimes were still there. They had fully assimilated and merged with the sand and mud, essentially becoming sand and mud themselves.
If the assimilation target were magically erased without a trace, they probably couldn’t withstand it. But physical attacks like stabbing, cutting, or striking were completely nullified. What surprised me most was that in this state, the “core”—the vital part of a slime—was absent. They had become the natural sand or mud itself.
Still, some sort of slime consciousness remained. When given commands, they could take slime form or crawl and move, even without a core, in their natural material state.
With two species using assimilation skills right before me and showing these effects, I had no choice but to accept this as a “fact” and “possible for them.”
This was what I confirmed yesterday, and the conclusion.
But from there, I became curious about why this happens and how it’s possible. That led me to focus on “mana.”
The reasons are, first, that ordinary slimes (those not advanced species) somehow leave only their core behind when they die, while their bodies disappear.
Second, from past observations and evolution experiments on magic-based slimes, it’s been established that slimes absorb mana and that each individual favors certain attributes of mana.
Third, from a previous spontaneous experiment where I let a Poison Slime use a spear magic tool, I confirmed that although it succeeded in usage, the slime weakened and shrank due to mana consumption.
For these three reasons, I had long considered the hypothesis that “a slime’s body is made up of mana.”
It’s basic magic knowledge and common sense that mana disperses unless controlled by a caster. If a slime’s body is a mass of mana, then the first point—its body disappearing upon death—can be explained, I think.
And if their body is mana, then perhaps the assimilation state is a form of magic? I usually dislike attributing everything to magic, but it’s a fact that in this world, “magic” exists that can make the impossible possible.
Moreover, if 100 slimes combine, they become a Big Slime; if 500 combine, a Huge Slime. It might not be that slimes themselves treat this as magic, but that slimes or the mana they possess naturally have the power or nature to enable fusion and assimilation.
That’s what I believe.
So, today I focused on the second reason mentioned earlier: “Slimes absorb mana and have preferred mana attributes,” and decided to think and experiment based on that.
Because,
“First, re-check.”
I investigated which attributes the two slime species capable of assimilation preferred.
The Mud Slime reacted strongly to earth and water, while the Sand Slime reacted strongly to earth and wind.
I had already observed this yesterday as part of my initial tests and confirmed the same results.
“The Mud Slime that assimilates into ‘mud’ prefers the attributes ‘earth and water.’”
More specifically, there is “mud magic” that combines earth and water attributes. I couldn’t believe this was just a coincidence.
