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!

Those auras, each spanning time immemorial, seemed to hark back to ancient times.


And each of those ancient stars surges with uncontainable vitality.


They stand in the sky, almost blotting it out in an instant.


This is Ninth Stage Heavenly Venerate, it's definitely a Ninth Stage Heavenly Venerate!


At this moment, a revelation reached everyone's hearts.


The four gods summoned by Chen Chang'an surely possess power sufficient to oppose a Ninth Stage Heavenly Venerate!


This isn't a rumor, but a fact they're feeling to their core!


The four Supreme Void Gods of Taiyin Palace represent Chen Chang'an's essence of the Confucian Path.


The moment Chen Chang'an became the Supreme Saint, they received immense boons.


The four Void Gods can now condense a semi-real haven.


Upon their full manifestation, they're truly on a par with the Heavenly Venerates!
