Fang Jinyu was also quite surprised by it. However, it wasn't because he hadn't thought that after hundreds of years, the person who was suspected to be the "spirit of the extraordinary book" and claimed to be the immortal officer would still find him. It was because he didn't expect the other party could cross worlds and easily make him enter a dream, even though he was an Incarnation stage cultivator!
The other party was in the immortal realm. However, Fang Jinyu was in the endless Sea of Realms!
Not to mention anything else, just the chaotic, turbid air alone could block everything.
