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!
....!

No one has ever doubted their fighting power.


But no one knew what this second reason was, so they patiently continued to listen.


"The second is that they have a group of followers, whom we call the Seven Star Lords.


The strength of these followers is said to be bestowed by seven life-giving ancient stars.


The most terrifying thing is that their lives are also granted by seven life-giving ancient stars.


As long as the ancient stars exist, the Star Army cannot be killed.


Even if they die, they will resurrect under the call of the current Star Lord!"


"Unless the ancient stars perish, the Star Army cannot be exterminated!"


The destruction of ancient stars, how many people in this world can cause the destruction of ancient stars.


The difficulty is no less than that of obliterating the nine skies.
