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!
....!

Chen Chang'an cast a disapproving glance at the discordant little old man.


Following that, he stepped out, standing between the two people.


Without veering to any side, he was positioned in such a way that the female disciple could move past him, thereby blocking the path of the pursuer.


"Are you intending to meddle in the affairs of our Shitian Sect?"


Seeing Chen Chang'an blocking his way, the heart of the man pursuing the female disciple instantly became apprehensive.


No other reason, but he was unable to gauge the depth of the person standing before him.


At first glance, he seemed like an ordinary man.


But at second glance, he was as vast and boundless as an ocean.


At the third glance, he transformed back into that ordinary appearance.


Though he clearly reeked of the mundane, he was elegant like a young master, resembling a celestial being exiled from heaven.
