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!
....!

"Correct, correct, among all the Demon Path Dharma Aspects I've seen, young man, yours is definitely among the top ones."


"However, with just that, who gave you the confidence to withstand me?"


The Void Demon Whale looked at the Great Demon apparition manifested behind Chen Chang'an, and a hint of mockery sparkled in its eyes.


Chen Chang'an's Great Demon apparition might be towering, but it was merely a typical Dharma Aspect after all.


Any being that stepped into the Eighth Stage would have it.


Indeed, the Dharma Aspect of the Eighth Stage Immortals was extraordinary, encompassing almost every force present in the world.


In this world, above the Eighth Stage, there is another immortal Ninth Stage, just like him.


The gap between the Eighth Stage and Ninth Stage was unimaginably huge. Regardless of Chen Chang'an's Great Demon Divine Skills, or even [Meng Po] with her profound understanding of Dao Palace, they were trivial in front of him.
