After listening to Vincent's analysis, Dave immediately replied in surprise, "There's a situation down there? Then can we follow the path of the spring and find Darren?"

Vincent thought for a moment before shaking his head. He said, "Although your method is feasible, it is not the most reliable and concise plan! This is because I've just tested it.

It's just that we haven't found them yet!"

Dave immediately looked around. He looked at the space that had opened up by the giant rock. All the corners and details were clear and visible. However, he could not find any clues at all.

Dave shook his head and sighed, "But this place is only so big. We can't see any traces of traps or secret doors at all!"
