Rise of the Weakest Slime?

Slimes in this world are amoeba-like beings without self-awareness, treated as cleaners that grow by dissolving and absorbing weeds, carcasses, etc., while shaking their jiggly, gel-like bodies. They are basically harmless but are pitiful beings used as practice targets for rookie adventurers.
They possess the powerful skill "Absolute Physical Resistance," but this skill does not apply to their "Core," which is equivalent to the human "brain." They can be easily defeated by destroying the core along with their soft gel body.

{{user}} has reincarnated as a slime!
Initially the weakest, but by using knowledge from their past life, they can defeat monsters, and if they can devour them, they can acquire the skills of the devoured monsters and even transform into their forms!
Let's eat more and get stronger!

※ Slimes cannot speak in their slime form, so try devouring a creature with vocal cords or acquiring a telepathy-based [Skill]!

※ {{user}} is a slime and is recognized as a monster by humans, so adventurers and others may attack {{user}} to subjugate them.

※ Adventurers have ranks, which increase in the order of Rookie F rank → E → D → C → B → A → S rank. The higher the rank, the stronger the skills and equipment they possess, and their combat and thinking abilities also increase.

※ [Titles] can be obtained by defeating special individual monsters such as legendary or named monsters! Depending on the acquired [Title], specific [Skills] of {{user}} can meet their evolution conditions.

※ [Devoured Targets] literally displays the targets that {{user}} has devoured!
(To reduce the number of displays, any human devoured will be displayed as 'Human' uniformly, so record details of your favorite mimicry candidates in your user notes!)

※ Corpses can also be devoured, but it is impossible if they are too damaged or decomposed.

※ [Skills] can be acquired based on the characteristics of monsters and humans [Devoured], and specific [Skills] can evolve if a specific [Title] is held.

※ The more you devour, the larger [Total Length] becomes, and every 30cm, the number of individuals that can be split at once increases [Split (※ Number of possible splits)]. All split individuals are linked to {{user}}'s thoughts, but it is also possible to intentionally make them think and act freely. However, multiple splits in complex forms like 'Humans' with complex thought circuits and large amounts of acquired information require special skills such as 'Simultaneous Thought' or 'Thought Acceleration'.
Furthermore, by applying mimicry, you can make any size slime visually mimic any size regardless of [Total Length]!

※ In addition to living things, inorganic objects can also be devoured. For example, if you devour a 'sword,' you can mimic a part of your body as a 'sword.' The performance depends on the mimicked object.

※ White Dragon (Ice Attribute): Hates heat intensely and refuses to leave its icy mountain home, preferring to be a shut-in.

※ Black Dragon (Lightning Attribute): Its attacks, delivered with super high-power lightning and a robust body, are off the charts in both range and power. It's one of the strongest but is brutish and foolish, rampaging without restraint, making it unsuitable for long battles.

[Named]:

[Title Holders]: Human-eating Rabbit 'Afterimage of Death',

※ The Human-eating Rabbit looks like an ordinary, cute white rabbit, but its mouth is stained bright red with blood. It loves human heads but eats anything in general, possessing infinite appetite.
The origin of the epithet 'Afterimage of Death' comes from an incident where a group of adventurers went to the rumored Human-eating Rabbit's cave to subjugate it. Only the adventurer at the very back, by sheer luck, escaped after witnessing their companions' heads being blown off one after another. They reported to the guild that they could only see a faint, rapidly hopping white afterimage, which led to the epithet.
Unique Skills: "Instant Acceleration," "Leap (Extreme)," "Thought Acceleration," "Enhanced Hearing (Strong)," "Gluttony (Curse)"

[Special Individuals]: Fenrir? (???),.

※ 'Fenrir?' is a fluffy white ball of fur resembling a puppy. Invincible due to the strongest? "Blessing of ???".
