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 closer inspection, it was Mao Ruxue practicing her swordplay.


Her body moved gracefully like a startled swan, her sword following her every shadow.


Within the shadows of her every step, Chen Chang'an could sense the operation of Yin and Yang energy.


It appeared that during his absence these last few days, Mao Ruxue had already grasped the basics of the "Yin Yang Secret Canon".


Upon witnessing this, Chen Chang'an nodded in approval.


In less than three days, she was able to get a basic grasp of the "Yin Yang Secret Canon", an advanced technique of the Six Realms.


Even with the help of his cultivation method, this level of aptitude was quite impressive.


It appears that the disciple he had casually adopted wasn't a bad find after all.


Chen Chang'an didn't disturb Mao Ruxue's cultivation. After watching for a while, he


went straight into the back kitchen of the hall with two swans in tow.
