Hollow Island
Swoosh! Swoosh! Swoosh!
After killing Cain and butchering his subordinates, Ling Chen and the Primordial Shura Gods suddenly turned into numerous beams of light that streaked across the sky and disappeared above the giant maelstrom.
Even though it's only been a few minutes since Ling Chen has arrived at the 7th Ring of the Chaos Universe, his knowledge about this place was no less than a powerful expert that has been living there for centuries due to Cain's memories.
With Ling Chen's current skill and power, there's no need for him to peer into someone's brain or soul to read that person's memories and secrets.
Once he killed his opponent and absorbed his blood and life essence, it also came with all that person's memories as well.
However, if that person had a ban or a powerful restriction on his nascent soul, then he would get only a part of the memories.
