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! You've read Daoist Scriptures and gained a level in 'Heaven Opening Law', currently Level 6.]

....
[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!
....!

But, none of them anticipated that he would explode at this moment.


On the other side, facing everyone's astonishment, the City God ignored them as if he saw nothing.


Upon hearing the icy voice of [White Impermanence], he said nonchalantly:


"It's meaningless, just voicing my opinion as usual."


"Could it be, Sister Bai and Brother Black, you won't allow me to express my own opinion here?"


Seeing the City God's arrogant tone, although [Black Impermanence] was not disturbed, [White Impermanence]'s eyes were almost shooting out fire.


She was pointing at the City God, almost cursing out loud.


At this moment, [Black Impermanence] was more composed, and he held [White Impermanence] back.


Immediately after, [Black Impermanence] looked at the City God and said:


"'City God,' you are one of the four great Yin Official of our Rebirth Hall. Naturally, you have the right to express your words."
