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!

Another earth-shattering roar reverberated, following which, behind Chen Chang'an, up in the sky.


The sun hung in the sky, its radiant glow illuminating the entire Wuxiang realm!


Then, a muscular figure with ancient bronze-color muscles, showing a ferocious face, emerged from that big sun.


On the man, was barely anything but a scant amount of cloth, and in his hand was a bronze spear, which made him look like a native from a wild region.


However, even though he was wearing simple clothes, his momentum was overwhelming.


Waves of black energy were seen emanating from his body.


The powerful aura he gave off was like a god-demon that had walked out of Hell.


It wasn't like, he indeed was a god-demon!


The next moment, a deep majestic divine sound resounded from his mouth.


As the divine sound echoed, it seemed to be originating from ancient times.
