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!

What could Chen Chang'an possibly say in response to this?


Because undoubtedly, this old man Dao Tian had already said everything he might or might not have wanted to say.


The formation on this mountain had to continue to change.


Not only the hostile elements could be removed, but also the sneaky ones!


In the following days, everything returned back to normal.


Life on the Dao Cang Mountain continued as usual, eating and drinking.


However, unlike before, an extra mouth had joined in the feasting.


Sometimes, the old man Liu Qingshan would even come over to freeload a meal.


When they got drunk, he and Dao Tian would become fast friends.


Chen Chang'an decided to turn a blind eye to this, allowing the two men to frolic about.


As long as they weren't causing chaos on his mountain, it was fine.


As time went by, Chen Chang'an noticed that Dao Tian had indeed suffered severe injuries.
