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!

At this moment, it was as if the heavens were about to collapse.


Under this boundless suppression, Heaven and Earth were rendered extinct.


The countless creatures beneath were also subjected to this overwhelming terror. Their souls were invaded, they covered their ears in agony, and screamed at the top of their lungs.


But what good would that do? The terrifying slaughter was born from Dao, how could these beings that depended on the Dao possibly resist!


In a mere blink of an eye, these vast multitudes instantly fell to their knees.


That they had survived was already the greatest fortune!


In the sky above, the boundless Sea of Thunder, as though sensing immense fear, recoiled back into the heaven and earth within an instant.


Its Heavenly Daoist seal was promptly destroyed.


The six cycles of reincarnation, in this moment, had to be recognized by Heaven and Earth!
