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!

At this moment, Ancient Ling Immortal Monarch truly has an unquenchable desire to kill Chen Chang'an. After all, in all eternity, Chen Chang'an was the first one to cause him such significant damage!


As he finished speaking, Ancient Ling Immortal Monarch wasted no more time. He summoned all his power to launch this attack, determined to kill Chen Chang'an with every fiber of his being.


At the same time, faced with the ferocious attack of Ancient Ling Immortal Monarch, Chen Chang'an didn't dare to be careless. He could indeed sense a deadly threat from it.


If he were to be hit by Ancient Ling Immortal Monarch's deadly strike, he feared he would lose his life right here, right now.


"Old guy, you are really pushing your luck, aren't you!"


Even a mud man has a temper, let alone Chen Chang'an.
