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!

Is this the extent of the Seven Stars' power?


The Bone Beast Army was his lifetime's hard work, brought forth for intimidation.


Yet unexpectedly, instead of intimidating, it was easily shattered by Chen Chang'an!


That was the foundation he had worked so hard to accumulate!


He was furious, spinning and thrusting forward, leading the charge.


He wanted to cross the endless borders, arrive in the Heavenly Water, and put an end to the Star Army.


"Hmph! Old fool, you're courting death!"


But at this moment, Chen Chang'an took action.


Chen Chang'an extended a clenching right hand, boldly meeting Mo Yuan's advance.


After one strike, Chen Chang'an stood in place, unmoved, while the Demon Lord Mo Yuan was pushed back several steps.
