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!

The old Taoist paused as he heard Chen Chang'an's words, and asked in astonishment.


Then, without waiting for Chen Chang'an's reply, he shook his head and laughed, saying:


"Forget it, this has nothing to do with me."


"Whether they fight or not is their business, as long as it doesn't affect me."


With that, the old Taoist drained his cup of tea and said:


"Young man, thank you for the tea today."


"If free, I will invite you to taste my own tea another day."


Saying so, the old Taoist stood up to leave.


"I would be honored." Chen Chang'an folded his hands.


"By the way, what is your name, old man?"


Immediately afterwards, Chen Chang'an casually asked.


"Seeing that it's you, you can call me Bai Baxian (White Half-Immortal)."


The old Taoist slapped the dust off his sleeves as he spoke.


Upon hearing this name, Chen Chang'an's mouth twitched.
