My cow ran away

In the mystical fantasy world, Chen Chang'an was confined to the forbidden library as soon as he arrived,
The sky literally started falling from the very beginning.
Fortunately, at that very moment, his system awakened,
All he needed to do was to read scriptures, and he would keep getting stronger.
Thus, with the library filled with various books, a smile appeared on Chen Chang'an's face.

Years later, as time turned everything old, the world above and the world beneath were already in a desperate turmoil, with immortals descending to the mortal world, and gods and demons performed chaotic dances, making the lives of people unbearable.
Chen Chang'an stepped out of his seclusion one day, looking at the heavenly gods and buddhas scattered across the sky.
“I'm not targeting anyone in particular, but everyone here is garbage!”
That day, he swung his sword and parted the heavens, ever since then, Heaven belongs to Heaven, Earth belongs to Earth!

Become a Saint through Studying! Exposed by my little junior sister!

This old man was originally a blade of grass in the World Sea, born amidst Chaos.


The Chaos he was born into wasn't what Chen Chang'an understood as primordial Chaos.


It was full of everlasting substances, a place where the group of Immortals contended.


In simple terms, it's what people commonly refer to as ancient times.


However, he was born in the Immortal Domain at the end of the ancient era.


Active before the Prison God Elephant used its body to suppress Hell.


As Shen Xuzi had mentioned, not long after his birth, a great upheaval had emerged.


An unprecedented war enveloped the entire Chaos Sea,


Every day in the boundless World Sea witnessed supreme entities fighting chaotically.


That conflict made heaven colorless, and the World Sea was completely turned over.


The fairyland where he resided was also affected during that time.


A random ray of light cut it away from the World Sea, leading to endless drift.


By the time it stabilized, it was already in this world.
