Su Chen did not know much about ancient times.
It was rumored that in ancient times, this world was very prosperous.
Saints were everywhere, not to mention Nirvana Realm cultivators. And even Great Emperor Realm experts were common.
Legendary Real Immortals often stepped into the mortal world.
It was a very flourishing era.
The powerful sects of that time were not like those of the present when they would change their names to sacred sects or holy lands as long as they had a Saint Realm expert.
After all, Saint Realm experts in ancient times were as common as Nirvana Realm experts of the present.
However, a long time ago, a great upheaval occurred in the world, with a massive invasion of dark creatures, and even the Central Plains could not escape from the disaster.
The native cultivators battled the dark creatures, causing the entire world to become damaged.
