The even MORE ultimate weapon.

"Wassup?" The goat head noticed my appearance.

"I came here with some news, but I'll tell you all about it in a week. More importantly, I need you to do a taste test." I pulled the severed arm out of my inventory.

"Oh, where'd you get that from? All the folks around here are blown to tiny pieces, and this arm is perfectly fine." Blood looked at me with suspicion.

"I didn't steal it from anyone or something like that, it's mine. I accidentally cut it off.. Ahem, nevermind that, could you taste it to see if my hands are any good?" I never thought I'd say this sentence, ever.

"High-level blood is the best." Blood widely opened his mouth.

I chucked the hand to him, and he caught it like a little doggo. Isn't high-level blood made of water though? Maybe there's some ingredient that humans can't taste which doesn't negatively impact our health.

"Oh yeah, delicious." He chewed the hand with so much pleasure that even I wanted to try some of my own flesh now.

"Hey, guess what?" The goat head called out excitedly.

"What is it?" I walked up to him, curious.

"Your blood was so good it helped me break through to the next evolution." Hold up, what? Next evolution?

"You've never told me about the existence of evolutions! What the hell? Whatever the case, you're now stronger or whatever, right?" I was so confused, but at least I now knew Blood upgraded.

It was a huge dump of information from thereon. Blood told me all about evolutions, and that every species can experience it.

The premise is simple - you need to fulfill a condition, which is determined by your species. Each individual of the same species has the same condition that has to be met, for example, a rabbit.

The condition for a rabbit to evolve is to kill one of its natural predators.

As Blood and I just found out, his condition is to consume some very high-level blood. Some races have a condition that is really hard, and some just have abstract conditions that haven't been discovered yet. That is also the case for humans, who don't yet know the condition to evolve, and even if they do, it's being kept secret.

Because of all the reasons above, most individuals never get to evolve.

"Cool, but what happens after evolution?" Blood's body hasn't changed yet, so I assume you can choose when to evolve, or it just happens gradually.

"You get a choice of two evolution branches. The two I got are, let's see.. [Attached Morph], and [Twin Headed]." Then the goat head proceeded to read out the descriptions of both branches.

[Twin Headed] gives you a second head - duh-, but the second head just mimics everything the first head does, allowing you to cast double the spells or consume twice more objects. The downside is that blood consumption is doubled.

[Attached Morph] Allows you to morph and change your shape, size, and other details around, but you have to be attached. You might remember, the first time I saw Blood, he was rooted to the ground. In other words, he can change his shape however he wants as long as he is rotted to something.

"Well, I think we both know which is better." I eyed the goat head.

"Yeah." He said and chose to evolve [Attached Morph] without a second thought. It was the perfect ability for us; you'll see why in a second.

"So, did the evolution work?" I asked, to make sure.

"Indeed it did. Alright, you know what to do." Blood grinned.

I clenched my teeth, and, having cleared my mind, sliced the half of my arm below the elbow right off. I ran over to the goat head, picked him up, and brought him to my hand, where he then released his roots.

"Argh!! Your roots fucking hurt!" I slammed the ground with my fist in pain, while Blood was attaching to my arm.

~~~

It took him two hours to carefully sprout the roots into my body without damaging me too much, and now he was finally able to use his ability.

"You.. haa.. Have.. haa.. no clue.. how much pain I went through during these two hours." I was still gasping air from the shock.

"I can tell. Welp, I'm morphing now." AS he said that, he started becoming smaller and smaller, eventually becoming the right size to be used as a replacement for my hand.

Since he was able to change shape however he wanted to, he now became a very practical hand extension that could be used in numerous ways. Also, even if the arm does get cut off, he could attach himself back without much trouble with the help of the roots.

The only difference is the look, which is rather cool, being honest with you.

"We did it. YES!!" I was so hyped to try out my new hand.

"It wasn't easy, connecting to your nervous system. Well, you should be able to move your arm now." As he said that, I tried stretching the hand, and it worked like a charm. It felt like I've been using it for my entire life, and I was even able to make his size the usual gigantic.

I played around with it a bit more, and then we finally got to do the most awaited test.

I pulled out the modified knife from my inventory and picked it up with my right hand. Well, I actually picked it up with blood's tongue, but it felt just like using my own fingers - no. It was even easier and more convenient.

I stretched the hand out while holding the knife, and swung it horizontally. In a single swipe, we cut down a dozen trees.

"Wow." Blood looked at the destruction in awe.

"Well, this is cool and all, but that's not the coolest thing of today. Create a blade of blood." As you know, the goat head is able to manipulate blood in any way he wants' so he can make an atom thin blade, though that would require him to get better at controlling it.

The better blood he uses, the stronger his blood manipulation skills will be, so he created a blade that came out of my hand, and it was made from my blood.

"Let's see.. I didn't lose any Health. Oh, that's because you're now considered as an extension of my body." And most importantly, I now had a weapon which scaled directly with my power, and, if you're not aware of it already - those are the strongest weapons in any RPG.
