Alex Moriarty, an orphan, was transmigrated into a high-level martial world after being murdered by his so-called little sister, the very person he had always protected with his life.The world he arrived in was a parallel version of Earth, yet it had been completely transformed.Five hundred years ago, a strange and terrifying dark miasma descended upon the planet. Space itself cracked open, and through those rifts poured horrors beyond imagination. The land expanded to thousands of times its original size, reshaping continents and oceans alike.Ordinary animals mutated into ferocious monsters, while mythical beings such as Godzilla, dragons, and phoenixes crossed over from unknown realms.In a single night, eighty percent of humanity was wiped out.The few survivors were preserved only because of a mysterious sanctuary known as the Light Domain.At its very center stood the Tower of Ascension, a colossal structure with one hundred stairs. When humans reached the age of fifteen, they were allowed to challenge the tower.The number of stairs they climbed determined their cultivation talent and bloodline. Before facing the tower, no one could cultivate or surpass the natural limits of the human body.But Alex was different.He possessed a game-like system that allowed him to cultivate even before setting foot in the tower. While others waited helplessly for their awakening, Alex grew stronger in silence, accumulating power far beyond what should have been possible.When he finally turned fifteen, he challenged the Tower of Ascension. Step by step, he climbed higher than anyone in history, reaching the hundredth stair as the sole existence in the entire universe to do so.At that moment, he awakened five Eternal Grade talents.[Eternal Grade Constitution: Primordial Chaos Physique][Eternal Grade Bloodline: Existential Nullity][Eternal Grade Eye of Revelation][Eternal Grade Cultivation Talent][Eternal Grade Sword Talent]With these five unparalleled talents and his Infinity System, which allowed him to cultivate passively twenty-four hours a day, Alex embarked on a path of absolute power. His journey was driven by two goals: to find his lost father and to make the Earth safe for his mother.

He, since childhood, had followed the Foreigner to practice the Defying Heaven Art, entering the most secretive special forces and becoming a fearsome assassin that made others tremble at the mere mention of his name. After a single failure, he took early retirement, but he ended up as the personal bodyguard for a rich heiress, a school beauty. Accidentally provoking some mysterious Cultivators, he gradually unveiled a hidden world of Cultivation beyond the mortal realm...

The eldest daughter of the Yan family, Yan Jinyu, who has been missing for 16 years, has been found. She is brought back from an orphanage by her fiancé, the Second Master of the Yin family.
