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!

"Oh my god, that's Purple Weeds, the Star of Destruction?!"


"No way, these are the North Black Seven Stars that flourished in the Mythical Era?!"


"It is said that each of the Seven Star Lords possesses the strength to independently reign supreme over the Heavenly Venerates."


"Each of them is considered to have an unsurpassable foundation capable of contending with the Great Heavenly Venerate!"


"The appearance of the Seven Star Lords is equivalent to having seven junior Heavenly Venerates, all serving Chen Chang'an!"


"Goodness, is this the power of the Void Gods of the Heavenly Cycle, how can it be so strong!"


"Ancient stars have reappeared, the Golden Age is about to begin!"


"Chaotic times are advancing! Chaotic times are advancing!"


The North Black Seven Star Lords that flourished in the Mythical Era have astonishingly reappeared in this world!


The world is going to descend into chaos!


The crowd continued discussing feverishly.
