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!

What's the point of lingering in this world alone?


"The Heaven and Earth divine weapons, the Dao path lies ahead!"


"Guided by the heavens, the path of the stars, open!"


Just like when he entered, upon Chen Chang'an's low shout, a winding rainbow light path appeared before him.


However, this time the rainbow light path was more complex than the one that appeared when he entered.


Taking a step onto the light path, Chen Chang'an took his last look at the straw cottage, saying,


"I will always remember your kindness."


Upon finishing, Chen Chang'an bowed seriously toward the straw cottage, then turned around, preparing to step onto the light path and be on his way.


However, as Chen Chang'an was about to leave, a booming voice suddenly exploded in his ear.


The voice was soft, but filled with endless authority, undeniable!


This voice came from within Chen Chang'an's body.
