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!

Upon hearing this, Mao Ruxue was slightly puzzled, not understanding what this so-called 'upset' meant.


[White Impermanence] nodded, then continued:


"We three are different from those who have been nurtured by the Lord since childhood."


"'City God' was the one who converted halfway."


"Converted halfway?" Mao Ruxue was once again perplexed, and it had never occurred to her that the term 'converted halfway' would crop up in this context.


[White Impermanence] nodded, then began narrating as if reminiscing:


"This 'City God' was an old demon from a hidden Great Demon Sect."


"He was always cruel and bloodthirsty, extremely violent!"


"A few years ago, when the Lord was still the 'Earth Bodhisattva,' this old demon forcefully took residence in Rebirth Hall."


"And competed with the Lord for the position of Emperor Song."
