As the sand was cleared away, a round object with irregular gear-shaped edges, yet reflecting a pure and solid light in the murky seawater, appeared before their eyes!
It wasn't flat like modern coins, but instead had a kind of ancient hand-crafted texture.
Riven's eyes widened behind her mask!
Lin Yu'an gestured to Riven, motioning for her to pick up the coin, intending to give her the right to discover the treasure.
Riven carefully picked up the coin, and under the glow of the flashlight, its details were clear and the craftsmanship was extremely exquisite.
In the center was the Spanish Habsburg Dynasty's crest with clear Latin inscriptions around it and the year "1714"!
Most importantly, its shape was nearly a perfect circle!
The moment Riven saw this coin, she was so excited she almost spat out her breathing regulator!
She frantically waved her arms in the water, grabbing Lin Yu'an's arm, pointing at the coin, and then at the direction the turtle had just left.
