Chen Feng piloted the submarine, following the preset coordinates to the indicated spot, and then began the descent—1000 meters, 2000 meters, 3000 meters…
After descending more than 6400 meters, Chen Feng stopped the dive. From there, they could already see a cavern beneath the seabed. The cavern was roughly the size of a soccer field, shaped like a sinkhole, except that it was filled with seawater and even had a vortex in the middle.
"Old Song, do you really think there might be an ancient relic down there?"
Looking at the pitch-black cavern resembling the gaping maw of a giant monster, and considering the strong underwater currents within, Chen Feng was concerned—would they be able to ascend if they went down?
"There shouldn't be a mistake, I've read about something similar in an ancient text…" Song Bojin quickly recited the description from the ancient text, clearly showing the effort he had put into research.
