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!

"Saint Chen, there's no need for formalities."


"We are aware of the purpose of your visit."


"Since Saint Chen, you are here to use the Taiyi Immortal Cauldron, we will completely adhere to your instructions during this period."


"As for what you can ultimately gain, it depends on your own destiny."


With that, Elder Tianyuan took a step forward and spoke to Chen Chang'an.


Chen Chang'an naturally had no objections to this.


"In that case, Saint Chen, let us begin."


Seeing that Chen Chang'an had no objections, the Five Patriarchs nodded immediately.


Then, with a loud shout, the five of them rose into the air.


They each sat in the east, south, west, and north positions above the Taiyi Immortal Cauldron, using their bodies as conduits to prepare to awaken the Taiyi Immortal Cauldron.


In an instant, after the Five Patriarchs took their respective places.
