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!

Thinking of this, Chen Chang'an's eyes suddenly turned icy.


"Both of you, I'm sending you on your way!"


He looked at the two saints across him, Wen Xuan, and said coldly!


Hearing Chen Chang'an's words, Wen Xuan and the two saints were instantly enraged.


Soon after, they yelled violently, and the celestial blades fell upon the Holy Palace.


With one blow, it shook the nine heavens and ten earths, and countless stars fell along with it.


The massive power instantly caused heaven and earth to cry out in sorrow.


"Both of you, today let's get a taste of what a real killing move is!"


Chen Chang'an grew more courageous as the battle progressed, his eyes gleaming with a chilling glow. He bellowed:


"Heavenly absolute kill, Zodiac Star Fight!"
