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!

He directly approached a seemingly middle-aged figure, about fifty years old, from the group, and with a salutation, he said:


Caught off guard by Chen Chang'an's call, Zhang Xuandao was a bit puzzled.


But, after a moment of doubt, he nodded and said:


Zhang Xuandao was not disrespectful and followed Chen Chang'an to a deserted spot:


Zhang Xuandao, the Peak Master of Tongtian Peak of the Tianshui sect, was, by generation, a fellow disciple of Sect Master Li Daoran.


He was approximately three to four hundred years old.


He had cultivated the five organs within his body to perfection and was a Great Cultivator in the late stage of the Fifth Realm, nearing perfection.


The purpose of his journey to Tai Xuan's secret realms was to assist Chen Chang'an in leading the disciples.
