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.

[Ding! Due to the Laws of All Heavens being added to your body, embellished with trembling Literary Qi of the Great Dao, you're rewarded with: Become a Saint on the spot!] 
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!
....!

"Holy crap, boy, how did you accomplish this?"


Watching the transformation, Shen Xuzi's eyes bulged, filled with disbelief as he looked at Chen Chang'an.


"It's quite simple. Although it's accurate that the Dragon and the Elephant are opposites, you forgot one thing, old man."


"I can wield more than just the Divine Elephant Prison Quelling Force."


Chen Chang'an, on the other hand, kept composed, dealing with Shen Xuzi's amazed expression.


[Ding! Detected the Azure Sea Heavenly Dragon's law barrier, it can be broken with Daluo's law combined with the Divine Elephant Prison Quelling Force!]


This was a message that Chen Chang'an received in his mind as soon as he stepped foot into the only Demon World.


Therefore, he asked Shen Xuzi about the location of the Heavenly Dragon's Treasure Vault.


"Correct, indeed. Yes, the Dragon and the Elephant have been at odds since ancient times, but what the Azure Sea Heavenly Dragon cultivates is also a part of Daluo's law."
