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!

Following a buzzing sound, the Tianshui Flying Boat steadily landed in the square. 


"I pay my respect to Sect Leader Elder Brother, Elders, and fellow disciples."


Chen Chang'an and Xuan Qingzi dismounted the flying boat, bowing their hands in greeting. 


Great Elder Li Xuandao laughed heartily. He approached Chen Chang'an and said,


"Chang'an, on this journey, you've truly fanned the flames for our Tianshui Sect."


"Thank you for your concern, Great Elder. This disciple is not hurt." Chen Chang'an bowed. 


"Let's go. Let's move into the grand hall." Li Xuandao nodded, his eyes full of admiration for Chen Chang'an. 


"Xuan Qing, you've had a hard journey." Li Xuandao turned to Xuan Qingzi. 


If Chen Chang'an was the one who bore the brunt of the journey, then Xuan Qingzi was the one under the most stress.
