The dawn era after the end of the half century has gradually rebuilt the order, abandoned civilization, and is full of undivided violence and desire.
The noble and powerful pioneers are in charge of the city, and the evil and mad plagues are in the wilderness.
Pure human beings who cannot mutate are the weakest, dominated by the rulers of the pioneers, and are not as good as animals in the wilderness.
A purely humanized young man with a worldly experience has quietly entered the WTO, holding a three-foot long knife and a long-distance desire to boil in the world of purgatory. From the nameless name to the sorrow of the Supreme Court, the name of the black ride is resounding!

- Description from Uukanshu (translated)

In the vast and grand universe, myriad treasures and artifacts existed, some crafted by the Grand Dao of the universe itself, while countless others paled in comparison to the might of those created by the Grand Dao.Yet, amidst the cosmic expanse, one individual achieved the extraordinary feat of fashioning a treasure on par with those birthed by the Grand Dao.This creator wasn't mortal, nor an immortal cultivator who had ascended to the pinnacle of power.Neither inherently good nor bad, this enigmatic figure stood as the genesis of countless races—a shattered being unlike any ever witnessed.Known by many names, the most prominent being the 'Son of the Universe'.Born directly from the Grand Dao of the universe, he was not the first entity to be brought forth in such a manner.The universe had previously given rise to beings governed by the System of Reality—known by various titles such as Heavenly Daos or World Trees—acting as gods of creation for innumerable planets across the universe.These divine entities, also referred to as the 'Daughters of the Universe', were exclusively female, with no sons among them.However, the Grand Dao of the universe defied this established norm, birthing a Son and thereby breaking the rules of the System of Reality.The treasure forged by the 'Son of the Universe' was lost to time, only to reappear fortuitously in an alley on a fateful night.On that particular night, a young man named Sam Hailstorm stumbled upon this extraordinary artifact, forever altering the course of his life.As for why the Grand Dao birthed such an unimaginable being, why this treasure found its way to Sam, and the purpose behind the Son of the Universe creating such a powerful artifact, join Sam on his journey of discovery as he unravels the truths and destinies that lie ahead.
