In this archipelago world divided by sea water, there is a group of special people - they drive boats through the stormy waves and send their thoughts and hopes to every isolated island.
Twenty-two-year-old Heng Tianqing had just taken over the postal route left by his father. The legendary postman who once traveled to thousands of islands disappeared forever in the vast sea in a storm.
I thought I was just delivering ordinary letters day after day, until the letter that changed everything appeared - there was no recipient name, no specific address, just a string of mysterious symbols and a line of words: "Please send it to the end of the world."
In order to complete this impossible task, Tian Qing must sail to the forbidden sea where no one has ever returned. There, he will uncover the truth about his father's disappearance, face the shocking secrets hidden deep under the sea, and in the test of life and death, he will protect the emotional ties that connect thousands of lonely hearts.
Some letters carry not only words, but also the fate of the entire world.
This time, what the postman wants to deliver is hope itself.
