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!

"So, you should go. I will explain everything to the Elders myself."


"Perhaps I can help with the problem that's troubling you."


"You?" Wang Shiyu suspiciously scrutinized Chen Chang'an from head to toe, his ragged clothes and unstable steps inciting her anger: "Little thief, are you trying to trick me?"


"Look at this, young lady." Instead of getting angry over Wang Shiyu's hostility, Chen Chang'an merely extended his palm in front of her eyes.


In the center of Chen Chang'an's palm, a faint green smoke was fluctuating and swirling.


When Wang Shiyu looked at Chen Chang'an's outstretched palm, she exclaimed in shock: "Is this Elixir Qi made from the Immortal Herbs?!"


"Exactly." Chen Chang'an grinned and nodded. It seems the young lady isn't completely ignorant.
