Liam was an ordinary man in his first life—an overworked office employee with no family, no support, and no future. Crushed by stress, loneliness, and endless overthinking, he died quietly from a heart attack, unnoticed by the world.

But fate gives him a second chance.

Reborn in a world ruled by magic, Liam awakens as a sixteen-year-old academy student where one’s destiny is determined by Core Awakening. Core grades define everything—from status to strength—ranging from Basic Yellow to the legendary Red Core, a power said to appear only once per generation.

Hoping to become extraordinary in this new life, Liam steps forward during the awakening ceremony—only to be branded a failure when he awakens a Basic Yellow Core, the lowest and most worthless rank. Mocked by classmates and dismissed as trash, Liam faces the same cruelty he once endured in his previous life.

But what no one knows is that Liam awakens something far more terrifying afterward—

A mysterious System that upgrades his trash core into a Legendary Red Core, making him the sole bearer of the strongest power of this era.

With a little brother to protect and a future he refuses to waste, Liam sets out on a path of silent growth, hidden power, and inevitable ascension—determined to never again live or die as an ordinary man.

In the earliest age of magic, the world was ruled not by academies or systems, but by mages who had reached Godhood. They were beings who had surpassed mortality, shaping land, oceans, and laws of magic itself.


This era ended the day the Demon Realm opened.


The Demon Realm was not a dungeon.It was not a trial.


It was a world of its own—a realm born from chaos, ruled by instincts, conquest, and endless slaughter.


From its depths emerged demon kings, demon armies, and at their peak—


A being stronger than any entity the mortal world had ever produced.


The Demon God waged war not to conquer land—but to erase existence itself. Entire continents burned. Oceans boiled. Civilizations vanished in weeks.


God-level mages clashed with demon lords, tearing the sky apart. For the first time, magic was pushed beyond limits.


But victory came at a cost history rarely spoke of.


Every mage who had reached Godhood died.


They sacrificed their divine existence to bind the Demon God itself—splitting its essence, chaining it beyond reality, and preventing it from crossing realms again.


Fragments of sealed demon realm energy leaked into the world, warping space and creating unstable zones. To prevent another invasion, surviving archmages reshaped these zones into controlled environments.


Among all magic disciplines, one was banned after the First Era.


Necromancers did not fear death.They commanded it.


During the war, necromancers raised fallen mages and demons alike, forming armies that did not tire, did not fear, and did not retreat.


The Demon God itself acknowledged them as threats.


After the war, necromancy was sealed, erased from official records, and branded as heresy.


There exists an unspoken truth among ancient entities:


And when it returns, raw magic will not be enough.


Only one force has ever threatened it directly—


A being capable of commanding souls, corpses, and fallen gods alike.


An army born from battlefields, extinct races, demon lords, and fallen gods. A force capable of flattening the Demon Realm itself.


Somewhere in the present era, a sealed Legendary Red Core pulses quietly.


The First Era, the Demon God, and the Path of Death
