Alex was just another ordinary gamer—until the day he died. Struck down by a terminal illness, he found solace in his favorite game, a vast fantasy RPG filled with powerful warriors, intricate politics, and world-shaking events. But before he could see the game's ending, fate had other plans.When he opens his eyes again, he’s no longer Alex from Earth. Instead, he’s Alex Dragonheart, a nameless extra in the very game he once played. Not a protagonist. Not even a villain. Just an unknown side character who was fated to die early, forgotten by history.Armed with only half of the game’s knowledge, an unawakened bloodline, and a mysterious sealed skill, Alex is thrown into a brutal world where strength is everything. His beloved younger sister is sick and needs treatment, but his past self had been powerless to save her. Not anymore.Determined to rewrite his fate, Alex will rise through the ranks, manipulate events from the shadows, and seize power that was never meant for him. If fate refuses to acknowledge him, then he’ll carve his own legend—one that even the gods will fear.After all, in a world where only the strong survive, even an extra can become a nightmare.( Okay guys just because there is a system tag does not mean he will get everything handed to him he will have to work hard to attain power because I will make it so )

Jacob Steve, an Old Man, died at 116 after living a whole life.

But Jacob always had a dark side, which he always suppressed and hid from others.
However, in the later years of his life, when death was inevitable, he understood there wasn't any point in having wealth, knowledge, or desires if you couldn't have a life to enjoy them.

He became obsessed with fabled immortality and devoted his reaming life to extending his fleeting lifespan, but just like any other failed.

However, he mysteriously got another chance at life and found a way that led to fabled immortality.
But he was also forewarned that the way led to it was filled with blood and darkness!

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!
