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!

Upon seeing the mysterious snake symbol, the old man of Destiny was taken aback. He turned to Bai Baxian, his tone serious and alarmed.


In response to the question, Bai Baxian let out a sigh and said,


"Senior brother, I won't lie to you. Before coming here, I cast a divination for myself."


"If I get involved in this matter, I will surely incur some unforeseen great horror, leading to my immediate demise!"


"And not only will I perish, by that time, our entire Destiny Realm will be subjected to an unstoppable catastrophe!"


"This is a calamity from ancient times!"


"I tried to resist this disaster, and as a result, I ended up in the state you see now."


"The Abyss Serpent has turned against me."


Next, Bai Baxian looked at the old man of Destiny and said,


"Senior brother, can you trust me this once and give up on this deduction?"


"Junior brother, are you serious?" The old man of Destiny looked at Bai Baxian solemnly.
