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!
....!

"In those memories, I felt like I wasn't from this world, but from a place called the Daoist Realm."


"The Daoist Realm doesn't belong to the three thousand realms, but it seems to float freely in the Endless Sea. There are many powerful people there, far exceeding this place."


"I've forgotten who I was there, and I don't know how I came to be here. But my heart keeps telling me to go back."


"I vaguely remember that I seemed to hold a high position. I had uncommon talent and strength, but in the end, it seemed that someone had betrayed and killed me."


"I can feel a great sense of dissatisfaction within me."


"I don't know if there's a path from this world to that one, but regardless, I want to go back and see."


"Even if it's only to follow my heart's desire."


After speaking, Mao Ruxue looked at Chen Chang'an and apologized:


"I apologize, brother, for telling you such an outrageous story."
