The old man continued to move forward aimlessly without even looking.
His left hand kept making gestures, positioning the tracking aura left on Lin Zheyu.
But no matter how he urged the secret technique, he didn't receive any feedback at all.
If he couldn't perceive whether the mark still exists, Fan Hongwei would doubt if that little guy found a way to remove the tracking mark.
"What method did this little guy use that can actually block the tracking mark for so long?"
Fan Hongwei was somewhat surprised.
The tracking mark left on Lin Zheyu was extremely extraordinary. It couldn't be blocked by ordinary magical treasures.
The magical treasure that could block the tracking mark he left isn't something a martial artist at Lin Zheyu's strength level could drive for a long time.
He really is a surprising little guy.
"I want to see how long you can block it."
Fan Hongwei smiled slightly and continued to stroll on the perilous earth of the demon cave.
