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!

As Yu Xuantian and Dao Taixu fell into a silent conversation, the massacre in the sky continued unabated.


Furthermore, it was even more unparalleled than before.


With each successive slaughter, the Six Daos on Chen Chang'an became more substantial.


All Six Daos were displayed, clashing with the dark skies under the incarnation of the Heavenly Disaster in the form of Yin Tianzi's Thirty-Three Demon Lands. The battle was vigorous, causing the whole sky to tremble.


Yin Tianzi, worthy of being a Heavenly Venerate who could achieve supremacy even in the era of Daoist perseverance, had indisputably strong Dao cultivation.


The heavens and earth changed colour when the Thirty-Three Demon Lands were displayed. If it weren't for the cycle realm opened by the Six Daos' reincarnation, Chen Chang'an may not have been able to resist against them.
