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!

"Indeed, there is a realm beyond the Immortal Monarch."


"The people of this world refer to this realm as 'Dao'."


"In the distant past, a tower appeared between heaven and earth."


"According to legend, whoever can pass through this tower will obtain the greatest secret of this world, and then begin the path to a higher-level world."


"I've always been unsure if this legend is true but now, when I see the token before you, I know it is!"


"The Heavenly Dao Token?" Chen Chang'an wondered.


"Yes, right, the Heavenly Dao Token!" Shen Xuzi nodded.


"It is said to be a token that opens the path to a place called the Daoist Realm. It was issued by an enormous entity within the Daoist Realm called the Heavenly Dao Academy. Whoever possesses this token has the qualification to enter that world and can use this token to practice within that entity."


"That is cultivation that surpasses the level of Dao!"
