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 finishing her sentence, Mao Ruxue took out a unique yellow token from her bosom.


Chen Chang'an reached out to receive it, a faint fragrance still hung on the token, paired with a lingering warmth from the girl.


Seemingly aware of this situation, a blush creeped across Mao Ruxue's cheeks as she saw Chen Chang'an accept the token.


Although she might be quite direct and relaxed by nature, she was still a lady born into a family of scholars. She had been trained in all manner of etiquette and manners from a tender age and thus was very aware of the differences between men and women.


Therefore, despite knowing that there would be no issue in letting her senior brother see, she still felt a bit shy.


Thankfully, after seeing no reaction from Chen Chang'an on the other side, her blush subsided somewhat.


Taking the token in hand, Chen Chang'an looked it over.
