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!

That slaughter swept across the entire Xuantian Continent,


As an eternal saint, she bore the brunt of it, facing off against that Immortal!


When it came to strength, she was on par with that Immortal—


But if power were to be considered, she was far outmatched.


A few Ancient Great Heavenly Sovereigns rallied under the banner of that Immortal,


On the other hand, she was the only one on her side with the prowess of a Great Heavenly Sovereign.


There was even a shortage of Heavenly Venerates,


The power imbalance between the two sides couldn't be any starker.


But the Immortal's victory came at a cost—


his immortal status was severed, he was on the brink of death.


The Great Heavenly Sovereigns under him had all fallen, no longer capable of stirring up trouble.


The conflict, in the end, resulted in a pyrrhic victory.
