Monster evolution system

Opening his eyes for what felt like the hundredth time, he awakes to a new world once more. The cold air clung to his breath, mist swirling into the dimly lit room. His legs are wrapped in damp sheets, the fabric clinging to his skin like frost, freezing him to his bones.

The room is confined and small, with its walls made out of thin oak wood with a fire pit in the corner letting out its last crackle before dying down and turning into ash. 

I guess I'm alive again. 

He looks at his palms his eyes widening as he takes it all in, his heart racing as a smile unctuously forms on his face, He can feel everything, all his senses return after it was gone for a moment.

I'm alive again, for what will be my last time. 

No more second chances...I have to achieve what I can and plant a mark on this world that people will remember me for.

Then his eyes meet two pairs of extra legs beside him, both peeking out of the covers at the edge of the bed, as someone slowly wakes up and presses their small head on his shoulder. 

"Brother…" A child-like voice mutters grunting as they yawn themselves awake. "Are you finally feeling better?" 

Max, now Legion, finds himself turning his head to the boy, black hair curly hair encapsulates his face with a pair of onyx eyes contrasting with his very pale complexion. 

He's small, not passing the age of 10 maybe? If so I would have sensed a core unless I lost that ability.

"Big brother and Avix, what are you guys doing up already." Another one grunts at the next side of him, this time their voice more feminine than the other. 

A girl maybe?

He snaps his head around to see her and he is correct, it's a girl, this time her hair is a bright shade of blond with deep sea blue eyes which makes him feel as though he's drowning in them.

Who are they?

[Memories connecting to the current soul] 

The system interface appears once again, and without a moment's delay, a torrent of memories seems to overflow his mind one after the other. He's inside the stronghold of the orcs, being used as sucking bags for them to get stronger. 

His siblings are Avix and Anore, their parents vanished when they arrived here. 

Which means they were sold to become slaves. I'm inhabiting Legion, the owner of this body with a rare case, a cracked core, his only one which means he'll never make it to the age of eighteen, and he's only 16 now. 

Legion is the only one they have, so there is no way I can just drop them, I can't let his sibling be alone like their parents left them, so as a promise to the previous owner I'll take care of them. 

"Yeah, I'm feeling better." He says looking at them warmly. "Should we get ready for the day?" 

"Yes!!" They both cheered, as they dash out of the bed. 

Both twins, ages 7 so they haven't harnessed a core yet, that only happens at age 10 so they're safe for now. From what I remember even though Legion is constantly sick and in pain he works in the mines instead of letting them suck the magic out of his mana core. 

And every day before he goes to work he drops them off at an innkeeper, a friend. As of now, I don't have the luxury to sit back just yet, I need to to adapt like in both of my past lives, learn their lives and how things work around here.

Then when the time is right I'll put things into action.

He turns to get off of the bed, but something pops up, the system and all of his stats.

So I'm going to have two sets of abilities but would that stop my mana exposition at the age of eighteen? 

[No.] 

At the age of eighteen, if one's mana core is cracked, it will explode when their body mutuality has reached its adult mod which means they can allow full mana consumption but since the fractured core is given a limit already the mana will be transferred into it unwilling and it burst, causing a phenomenon called the calamity, that hurts themselves and the people around them. 

Then, I'll have to find a way around it somehow, for leveling up should be at the top of my list.

[Daily tasks and workouts will begin tomorrow.] 

So it's giving me time to adjust myself into these settings. 

"Brother! Aren't you getting ready?" Anore asks as she puts on her tattered coat, and busted boots, with a smile plastered on her face mixing with her red nose and cheeks. 

How could they live like this?

His head drops for a second and Anore runs up and lifts his face, "Are you still feeling sick?" She titles her head. "You can stay home we'll just go help Aunty sell." 

"No, no." He shakes his head. "It's fine, I'm ok don't worry about me." he smiles back, before noticing Avix trying to put on his coat but struggling to get it onto the next hand. "Come here." He signals, and he moves over. 

I need to give them a better life for the owner of this body. I witness all his pain and struggles from his memories to make them happy and I won't let his suffering go with a reward. 

Helping Avix he recognizes his small frame, but all he can do is look away for now.

Soon it will get better...I should probably get ready as well.

Getting up he then gets up to get ready, but his legs feel like noodles and the world titles as he heads for the floor. 

Shit.

"You're going to fall!" A squeaky voice shouts aloud nothing like the kids own, but someone else. 

Shifting his eyes to the voice he sees a small, head-sized baby dragon with a shell still on its head. Its blue scales glint gently, as its tiny wings flap up and down, with its eyes pristine golden staring at him. 

"The dragon!" He mutters as he crashes to the floor.

"Brother!" Both his siblings drop to his side, and looks at him worried. "Are you sure you're not sick?" 

"Yes, the dragon." It flaps his wings and moves closer to him. "Hello, master!" It grins as a puff of smoke leaves its nose and covers his vision.
