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!
....!

Become a Saint through Studying! Exposed by my little junior sister!

The moment Mao Ruxue heard these words from Chen Chang'an, she was left utterly baffled.


From where did a corpse come from under the mountain?


And more importantly, shouldn't we be concerned about Cheng Huang right now?


However, Chen Chang'an didn't respond to Mao Ruxue's confusion.


"Right, it's getting late. You should go back and rest, junior sister."


When he reached the doorway of his room, Chen Chang'an turned his head slightly to look down the mountain and nodded satisfied.


He didn't expect to only test the power of the Formation slightly, and it seems to be quite good.


Burning the Essence Blood at every turn was not acceptable.


It seemed he needed to find an Eight Realm Master Formation to add in first.


What about adding some Primordial Dao patterns?
