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!

Although in recent years Chen Chang'an had been rarely showing himself in front of the beings of other realms, since the integration of the three thousand realms, his name, Supreme Saint Chen Chang'an, had already spread throughout the entire three thousand realms.


As one of the three thousand realms, Tianyuan World was naturally among the first to be affected.


Even before the integration process had begun, they had heard about the great name of Supreme Saint Chen Chang'an!


Moreover, after the integration of the three thousand realms, when Chen Chang'an revealed his Dharma Body above the Holy Palace, suppressing the four Great Heavenly Venerates with the technique encompassing the Ten Thousand Laws.


The name of Supreme Saint Chen Chang'an was engraved onto the hearts of every disciple!


A single man who slaughtered four great Semi-Saints! Who in the world could possibly do such a thing?


Except for this man, there is none other!
