The reason Carlos knows about the Illusory Demon Stone is because this is his third time entering the Wild God Secret Realm!
He's already forty years old this year. More than ten years ago, he had already been to the Wild God Secret Realm. During the past experiences, he was only interested in Wild God's Soil and Wild God's Breath Soil, disdainful of some accompanying materials nearby.
But upon careful recollection, he indeed had some impression of this Illusory Demon Stone!
Because of the very powerful effect of the Illusory Demon Stone... confusion!
Yes, confusion!
This is a rare stone with special magic power!
If you stare at it for a long time, you'll easily fall into a self-created illusion... The stronger a person is, the more real the constructed illusion becomes, and the harder it is to come out of it.
There are even Supreme Realm Powerhouses who have been trapped to death in illusions created by the Illusory Demon Stone...
