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, they didn't hide their murderous intent in the slightest,


The massive force trembled heaven and earth.


This was not a power that the creatures of the Six Realms could unleash—it was the real seventh realm god devil!


Perceiving this, Tianyuanzi's face changed drastically.


He had never imagined that the four demons—once seemingly harmless—could have suddenly surged in power.


At this moment, they revealed their unparalleled killing intent.


However, before Tianyuanzi could react, Kuafu—one of the demons—made his move. He roared and stepped forward, then lifted the great axe in his hand and brutally chopped down from the sky!


An explosion echoed and instantly broke out between heaven and earth. The overpowering force made heaven and earth roar in protest.


At this instant, heaven and earth were overturned!


This was slaughter—the slaughter that destroyed heaven and earth.
