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!
....!

This moment, boundless Demonic Qi surged from all sides of Heaven and Earth, as if everything was collapsing.


Yanluo and the other two were surprised, their eyebrows furrowed as they watched this scene. As for the Void Demon Whale, they had no idea what was happening.


They had seen the move that Chen Chang'an had used before, more than once.


However, they had never seen anything like the scene now.


When could Emperor Song's Great Demon's Dharma Aspect increase in size again? it was nearly as large as the body of the Void Demon Whale now, wasn't it?


And with just one wave of his hand, he could extinguish the Demonic Qi of a Ninth Stage Great Demon?


Typically, only a power of the same level could obliterate an invincible Ninth Stage attack, right?


The more they thought about it, the more puzzled Yanluo and the others became as their brows furrowed tighter.
