Lin Yue woke up on the beach, remembering nothing, and only had a sealed cylinder from the Deep Sea Institute in his hand.
There is a sea chart in the tube, with a red circle drawn on it. The location of the red circle is deep in the South China Sea.
He followed the clues and found Shen Nianwei, an archaeologist whose father disappeared in the same sea area three years ago. The two men's charts were put together and pointed to a four-hundred-year-old shipwreck on the seabed.
There is a diary in the sunken ship. The owner of the diary went to sea in 1566, encountered a storm, and sank here. He wrote on the last page: "There is a copper box on the deck with words engraved on it - 'Jiajing', 'Xu', 'Dadian'."
Since then, people have come looking for the ship every few hundred years. In 1402, 1566, 1952, 2001... Some people died, some disappeared, some went in and never came out.
Now, someone else is here.
A black boat has been following Lin Yue. The people on the boat came from a family called Matsuura in Nagasaki, Japan—six hundred years ago they were Japanese pirates, four hundred years ago they were related to Zheng Chenggong, and eighty years ago they were Japanese invaders of China. They searched for this ship for six hundred years.
What they are looking for lies in a crack in the sea. That crack opens every six hundred years. In 2024, it's time again.
On the other side of the crack, sleep all the forgotten truths.
Lin Yue didn't think too much. He just wanted to know why he woke up in that sea, and what the grandfather who gave him the copper coins hid from him.
