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!
....!

After thinking briefly, Chen Chang'an said to Mao Ruxue:


"You can train a bit more in the near future. The sect's grand comparison will take place three months from now."


"If there's anything you don't understand, you can always ask me."


"I should be on the mountain most of the time."


Mao Ruxue felt somewhat uncertain towards her senior brother, Chen Chang'an.


Take the manuscript Chen Chang'an gave her last time, for example.


Even though Chen Chang'an had explained that it was left by the ancestors on the mountain, Mao Ruxue still found it hard to believe.


After all, she had never heard of such a cultivation method before.


That's why she always humbly accepted Chen Chang'an's invitation to seek his help with any doubts.


However, Chen Chang'an was unaware of Mao Ruxue's thoughts, and after his meal, he returned to the scripture depository.
