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!

One could see two slightly long, multicolored feathers atop this large bird's head. Also hidden within its cyan wings were streaks of colorful feathers, barely visible.


This is not any ordinary Cyan Bird. Damn it, it's a Cyan Phoenix!


Regrettably though, its lineage is somewhat mixed, greatly restricting its growth.


If that wasn't the case, those men just now wouldn't even have needed Chen Chang'an's help. This bird alone would have been enough to deal with them.


Chen Chang'an glanced at the large bird then reached out his hand. The next moment, a misty aura drifted from his hand.


This aura was from the Saint Medicine Chen Chang'an had stored away (most of which he had taken from Shen Xuzi). He had extracted some of the life essence from these medicines and infused it into the body of the Cyan Bird.


After Chen Chang'an had infused it with the life essence, strange changes began to occur.
