I Have the Alchemy Emperor in My Head - Chapter 2546 - : The Number One Emperor Since Ancient Times

The world where the Hero and the Demon King continue to oppose each other. The grand magic from the Hero and the Demon King cross over worlds and exploded in the classroom of a certain high school.

The students who died in the explosion will be reincarnated in a different world. The protagonist, who had the lowest reputation in the class, was reincarnated into a spider. Nevertheless, she adapted quickly to the present condition with strong willpower.

This is a story of she who has become a spider trying whatever she can to live.

What would happen in a world governed by the Ascendants, the highest level people in the System, when the System itself resets due to the death of its creator? When the levels, classes, skills, and even Legendary Feats of every user are wiped, and everyone is sent to a new dimension to start all over again? Alexia, on what should’ve just been her very first Dungeon dive in the Royal Dungeon, finds her life, her body, and her entire world changing after the Creator of the System itself forces her to kill him, resetting the System entirely. But after being turned into a quantum reaper and given the powerful quantum element as a ‘prize’ for her Legendary Feat, will she thrive? Or will she fall? What to expect: Quantum Magic using Main Protagonist, Anti-Hero Protagonist, System Reset, Polearm using Protagonist in terms of their weapon, and LitRPG. What not to expect: Magic to follow science and reality based on quantum mechanics. There will be some skills that will have some relation to quantum mechanics in the much later books of the story, but definitely not at the start, and not too deeply related. Do not expect magic to follow laws of science. The world that the main character is in prior to the Reset is not a modern world. It is more similar to a fantasy world with swords and sorcery in terms of the morals and ethics of the people just with modern technology. Furthermore, Alexia is twenty years old. Furthermore, the vast majority of the reviews are out of date due to me editing the story as it goes on.

In a certain world, there was someone who excelled in magic combat, people called him 『Sage』. Seeking the strongest combat art, he devoted himself to research every magic and combat arts in existence. And the conclusion he arrived at was very cruel, 『My body is not fit for magic combat』. Yet he didn’t give up. He sealed his own soul with a magic art, and was reborn in a far-off future. And the magic theory in the completely changed world he saw there was of unbelievably low level.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.
