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!

However, a terrifying surge of Demonic Qi emerged next to him.


Wherever he passed, swathes of people were dying incessantly, as if their souls were returning to the underworld.


Every soldier who died did so with a look of terror, as though they had encountered some great horror before their end.


In fact, Chen Chang'an was indeed that great terror.


A Demon Emperor would never show mercy.


Zhao Tiande looked down at Chen Chang'an and shouted coldly.


Chen Chang'an stopped upon hearing this. He looked up at Zhao Tiande and the others in the sky, and he smiled slightly:


"Oh, a few old farts. I thought you wouldn't show up."


As for Zhao Tiande, this old fellow, Chen Chang'an was familiar with him. He was one of the ancient Sect Leaders of the Taiyi Sect.


An old antique who had managed to survive from the previous era.


Now, he is in charge of the most mysterious faction within the Taiyi Sect, the Chaotian Gate.
