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.

That day, he swung his sword and parted the heavens, ever since then, Heaven belongs to Heaven, Earth belongs to Earth!

They hibernated deep within this boundless, undying forest; their brutal aura raged uncontrolled, stirring the heavenly patterns in the sky above them.


Chen Chang'an had no doubt that if these ancient giant beasts broke through the defense line and charged in, it would be an absolute catastrophe for every living being inside.


At that moment, Chen Chang'an mostly understood what Dao Tian had been doing.


Dao Tian had been constantly repelling these ancient giant beasts. Moreover, if Chen Chang'an's guess was correct, the injuries on Dao Tian were likely caused by the two seventh-realm giant beasts which he sensed in this undying forest earlier.


While Chen Chang'an was walking and thinking, he suddenly came across a city.


It was a stronghold called the Undying Emperor Barrier.
