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!

It was as though he was speaking to the air, his voice sudden and eerie.


But in the next moment, something miraculous happened.


As soon as Chen Chang'an's words fell, in the sky above Dragon Sealing Village, streams of black smoke immediately surged forth from the limitless heaven and earth.


After that, this smoke traveled at a speed that was too fast for the naked eye to track, quickly reaching Chen Chang'an's side and finally gathering into a mass.


When the smoke dissipated, a silhouette appeared before Chen Chang'an.


This was an old man dressed in cloth garments, his white hair flying, his appearance rather sharp.


"Sky Cloud Ghost King [Sky Cloud Ghost King], greeting, sir."


As soon as the old man appeared, he immediately greeted Chen Chang'an with solemn respect.


[Sky Cloud Ghost King] did not know who the man before his eyes actually was, or what this man had summoned him for, but at this moment, his heart was trembling to the extreme.
