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.
........

[Ding! Due to the Laws of All Heavens being added to your body, embellished with trembling Literary Qi of the Great Dao, you're rewarded with: Become a Saint on the spot!] 
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, it's a pity that everyone immediately realized that there would be no reinforcements.


Firstly, at this moment in the high altitude of the Wuxiang realm, the main world with Zhongzhou at the core, was almost entirely wrapped in a thick barrier.


Within this barrier, people outside would not notice any abnormalities here.


Furthermore, under the current circumstances, even if someone were to notice the abnormalities here, no one would risk offending the four heavenly venerates to come and assist.


Such terrifying power, probably even sects like the Taiyi Sect or Rebirth Hall could only stand by and watch!


The aerial battle was still ongoing, and the world-shaking slaughter was not yet over.


After the intervention of Demon Lord Mo Yuan and Ji Han, the destructive power of Chen Chang'an's killing move was indeed greatly weakened.


However, it was reduced to merely a weakened state.
