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!

Did I see him somewhere before? And it was not too long ago?


Upon hearing Mao Emperor's words, Father Mao became puzzled, rubbing his chin as he lapsed into deep thought.


Not for any other reason, but upon hearing Mao Emperor's words, he too seemed to have a familiarity with the Immortal Master.


Someone as gently refined and unrivalled as his daughter's senior brother, one should have a deep impression after meeting them once, so why couldn't he remember?


Suddenly, Father Mao seemed to have thought of something and looked up at Mao Emperor with surprise.


Amazingly, after Father Mao made such a conjecture, Mao Emperor on the opposite side had also thought of the same thing.


Then, the two looked at each other, both could see the surprise in the other's eyes.
