Ye Guchen was once the Star River Emperor, ruler of the primordial universe three million years ago. His original name was Yuan Qi, and he governed the entire Star River cosmos. But a million years ago, a mysterious force swept across the Star River: Creation Chaos. The gods fought valiantly to hold it back and finally sealed it away. Yet over the long course of history, one person grew covetous of this power. To claim it, he released Chaos and transformed it into his own energy, triggering another War of the Gods. That night, the entire Star River cosmos collapsed. The Star River Emperor sacrificed himself to defeat the enemy and protect the Star River, but his grievous injuries ultimately caused him to fall into the mortal world. Yuan Qi, fallen into the mortal realm, took the name Ye Guchen and secluded himself for three million years to cultivate. To keep Chaos from detecting him, he hid his identity and posed as an ordinary, unassuming mortal. He joined the Azure Cloud Sect as an outer disciple assigned to sweep the grounds. Though he appeared mortal, his strength surpassed that of the entire cultivation world, even the divine realm. With a casual wave of his hand, he could create a world or destroy the Star River cosmos. To eradicate Chaos once and for all, he feigned amnesia and pretended to be someone who only wanted a peaceful life in the mortal realm. Yet he was often ostracized by others in the sect. Tens of thousands of years later, every capable disciple in the sect had ascended, leaving him alone to guard it.
To improve his cultivation, he began a period of seclusion. Hundreds of thousands of years passed, and the sect had fallen into ruin. Only a handful of disciples remained, all at the mid Foundation Establishment stage. Seeking revenge and hoping to restore the sect, he began his struggle against humans, gods, immortals, demons, and Chaos.
