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!

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

Seeing this, Mao Ruxue immediately broke into a smile.


Perfect, her senior brother was still here.


"You girl, why are you standing there, giggling like an idiot outside the door? Why don't you come in since you're back?"


Chen Chang'an's voice came from inside the courtyard.


Hearing Chen Chang'an's voice, Mao Ruxue quickly responded,


"I wasn't deliberately lingering outside the door."


"It's just that seeing you looking so handsome, I was mesmerized."


"You little scamp, are you saying you won't come in just because you find me handsome?" Chen Chang'an asked, setting aside the book in his hand and speaking in annoyance. 


"Then senior brother, should I come in?"


If he had any proof, Chen Chang'an could reasonably suspect that Mao Ruxue was teasing him again!


Ah, never mind, he decided to forget it.


"Junior sister, how was your trip down the mountain?"
