Lu Changsheng did not speak, he just quietly gazed ahead.
"Buzz buzz buzz—"
At this moment, the demon detection plate in Qin Yunning's arms began to vibrate furiously.
The demon detection plate could sense demon qi and demon evil power within a hundred-mile radius.
Based on the fluctuations of demon qi and demon evil power, it assesses the approximate power level of the demon beast.
Qin Yunning traveled from Penglai Island all the way to Great Dream Marsh without encountering any attacks from demon kings, thanks to the demon detection plate.
Once demon qi fluctuations were sensed, she would immediately cast divine skills to conceal her figure and quietly move away.
The current movement of the demon detection plate indicated to her that there was a Fourth Rank Demon King nearby!
She then saw a misty fog and surging waves ahead, like a mountain emerging from the waves.
"Fourth Rank Demon King!"
