Day 41-50/Day 45

Day 45
Early morning, I left the mine and wandered through the forest alone.
Walking in the Unexplored Zone of my mental map, I discovered a [Gray Slime] (temporary name) that looked like a superior species of Green slime. The reason why I gave it this temporary name is because of its gray color, it’s size is twice that of a Green slime and the overall speed of its movements and the twisting tentacles is higher than I expected, the digestive power of its bodily fluids scattering around is much higher than the Green slime's.
As soon as I fought it, I realized that it was quite tough compared to Green slimes. 
More like, it was somewhat strange.
I figured it was the same kind of monster, so I attacked it with a spell from the [Fire] magic system but it wasn’t very effective, “Then how about [Pyrokinesis]?” when I tried it out it died pretty easily.
I deduced that Gray slimes must be resistant to the [Fire] magic system.
I picked up the gray nucleus that was rolling around and placed it in my [Item Box], then I searched for more Gray slimes, that's because I wanted to conduct further experiment to discover what other characteristics they have.
After about an hour, I hunted roughly 20 Gray slimes.
As things turn out, except for the [End] magic system I can’t use any of the other magic systems against Gray slimes effectively.
It seems like Gray slimes are resistant to magic itself, not just the [Fire] magic system and unless the magic's power is at a certain level it wouldn't work, anything below that level would be neutralized and if you add [Physical Damage Reduction], these two abilities would work perfectly together.
The basic slime ability [Physical Damage Reduction] can significantly reduce the damage from physical attacks or even nullify then if they're below a certain level. The slimes are supposed to be weak against magic but these guys gained some resistance to it and with its decent speed and high digestive power, what should have been a normal enemy - Green slimes - becomes a formidable opponent - Gray slimes - .
However, I wonder why they die so quickly when I use [Pyrokinesis]‘s flames and [Electromaster]‘s lightning.
Is it because it's not magic? I don't know what's exactly the reason, however, at least I know the “How to deal with/ Ways of Killing” Gray slimes, so I don’t care what's the real reason.
I took the 20 gray nucleuses out from my [Item Box] and ate all of them. The candy-like nucleuses are about 5cm in diameter. Although they are tasteless, they feel like candy when I pop them into my mouth and roll them around.
Ability [Physical Damage Resistance] learned 
Ability [Self-Replication] learned
Ability [Infused Liquid Restoration] learned
It seems like the physical defense ability that the Gray slimes had wasn’t [Physical Damage Reduction], but a superior version [Physical Damage Resistance]. 
I kind of expected it, they were very resistant to physical damage after all.
By the way, it seems like a slime multiplies by increasing its volume to a certain level then dividing itself into two. Well, I was able to understand this as soon as I learned [Self-replication].
I bit my finger and let the blood flow, soon after the blood began twisting and wriggling, I created a crimson colored mini version of me. Both my original body and my tiny clone are connected to some degree. I can share what I'm thinking and seeing with it.
I can see the clone in my own field of vision and I can also see myself in the clone's field of vision. It was a bizarre experience.
As expected, sense of touch seem to be impossible to share as expected, but it’s a good ability since it’s so convenient, even I think it’s foul play.
It’s not the kind of ability that could be appreciated immediately, but give it enough time to grow and its usefulness would show. It can be used to gather intelligence or determine the enemy's combat strength easily.
The material needed is my blood, so it's easy to replenish it since I can suck blood from others using [Vampirephilia].
After that, I hunted and ate things like Argiopes, Demon spiders Triple Horned horses, returned home, ate dinner, then slept.
