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!

Though it was a smile, it was not a hospitable one.


However, the five individuals below seemed to be well aware of Chen Chang'an's demeanor, they did not take offense or show annoyance, instead, they spoke earnestly with a bow:


"Your words mock us, sir. For thousands of years, the Demon World has been led by Rebirth Hall and our five forces."


"There were times when we had to rely on your leadership to get through crises."


"Now you are the palace lord of Rebirth Hall, thus you naturally deserve our respect." 


It was the Yuanchu Demon Lord who was speaking from among the five of them.


However, whether intentional or not, there was no longer any mention of the Ferryman of the Abyss in his words.


The original six mighty forces in the limitless Demon World were reduced to five by his words, as if the Abyss simply did not exist.


By this point, it was clear that the five Lords feared Chen Chang'an.
