This was a heap of steel wreckage half buried in the mud on the sea floor.
From its outline, it appeared to be a submarine, directly hit by a torpedo or a depth charge, cleanly broken into two pieces, so damaged that it was impossible to make out the model.
Lu Yao maneuvered his sluggish Divine Soul into it; everything inside had been turned into mush by the sea water.
It was estimated that before long, all traces of this submarine would be completely erased by nature.
He found countless dirty lumps of earth within the cabin, scattered around and seemingly worthless, but Lu Yao had already discerned their true nature through the Heavenly Eye.
With a gentle brush, the unassuming clumps revealed a hint of golden gleam. These were all gold! Roughly estimated, there were about two tons.
"Not bad, a good start," he said.
Eager and fighting against the deep sea pressure, Lu Yao quickly opened the Space-Time Bubble and stored the gold inside.
