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!
....!

The next moment, Mao Ruxue voiced her doubts.


In response to Mao Ruxue's question, Chen Chang'an shook his head.


"The reason the mountain gate sets up such spiritual fields not only serves as a test for the newly joined disciples, but also as a benefit for them."


"Over the years you've been up the mountain, I haven't had anything good to give you, so I'll give these spiritual fields to you."


"Besides, these spiritual fields will eventually be handed over to you in the future. There's not much difference between handing them over now or later, so I might as well give them all to you."


Upon hearing Chen Chang'an's words, Mao Ruxue was stunned. From the sound of it, was there a feeling of entrusting responsibility?


"Brother, are you going to pass the position of the mountain lord onto me?"


The next moment, Mao Ruxue asked in surprise. At this moment, she felt like happiness had come too suddenly.
