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.

[Ding! Due to the Laws of All Heavens being added to your body, embellished with trembling Literary Qi of the Great Dao, you're rewarded with: Become a Saint on the spot!] 
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!
....!

However, the next moment, just as Chen Chang'an was puzzling over how to interconnect, a fierce swaying suddenly occurred on the body of the ancient sacred spirit tree in the outside world.


Then, from the tree trunk, a huge crack appeared out of thin air.


In the fissure, a terrifying aura surged, making the fissure look like a gate to Hell, utterly horrifying.


What's even more terrifying is that within the fissure, a monumental suction force was constantly emanating.


It voraciously devoured everything, anything within this space was drawn into it!


"Kid, run! This damn thing is a time rift, if you're sucked in, you're done for!"


Next to Chen Chang'an, Shen Xuzi was scared shitless by this sight, and he immediately shouted loudly.


Time, is an area he dared not venture into, even during his peak!


Now, after Shen Xuzi's reminder, Chen Chang'an's consciousness also returned to his body.
