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!
....!

Become a Saint through Studying! Exposed by my little junior sister!

But, twenty-eight starry constellations have never existed in this world before, right?


Something nonexistent in this world was summoned by people from this world?


However, at this moment, he suddenly understood why Xuan Qingzi brought these disciples to him.


If it's really because of the Void God of the Celestial Cycle, it seems that no one else can solve this problem but him.


"Junior Brother, Do you understand now?" Xuan Qingzi glanced at Chen Chang'an and helplessly shrugged his shoulders.


"After Daozhen and the others awakened your legacy of the Great Scholar and cultivated the Void God of Celestial Cycle, it seemed like they could no longer cultivate anything else."


"Every time they achieve a little result, it's interrupted by your Dao, or the Void God of the Celestial Cycle."
