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!

The original land of Mingtu, the black river, has disappeared without a trace, replaced by a long void that stretches out here.


Throughout heaven and earth, there is no longer any trace of Mingtu's existence.


Only the wisps of black aura that are being released, continually proving to the world, once upon a time, an ancient deathground used to be entrenched here.


The spectators stared in shock, and the heavens and living things looked stunned.


Such a huge deathground was simply gone without warning.


They looked up at the figure in the sky where a gigantic entity wrapped in purple lightning, large enough to cover more than half of heaven and earth, stood towering.


Its overwhelming presence caused the surrounding spacetime to crumble.


Underneath the giant entity, a very slender figure was wrapped in pitch-black, standing alone.
