The Nether River was too dark; even with Gu Shen's spiritual power, he couldn't extend it too far.
After the transaction was completed.
He saw a faintly flickering "light spot" in the pitch-black river...
That should be the direction the devil indicated for him.
"What is that light spot?"
Gu Shen didn't rush to move but asked a question instead.
"Sorry... answering that question is not within the scope of our previous transaction."
The devil said nonchalantly: "I am only responsible for pointing the direction for you, anything else is none of my business. If you want to remove the 'spiritual poison' from this Nether River, head in the direction I pointed."
This guy has become smarter.
Gu Shen didn't say anything; bound by the iron rule of the Ruler Space, he was not worried about the devil playing tricks on him.
The deal was already made.
It had to show him the way, and that light spot surely marked the location of the spiritual poison!
