Qin Ke, an orphan among the stars, finds a beautiful glass marble in a garbage heap. Inside it is a tiny sailboat.
After accidentally falling into the water, she discovers that the marble lets her breathe underwater.
Later, she realizes that the colorful world beneath the sea is even more wonderful than the world above.
The rare and expensive red peppermint angelfish, the blade-fin fish with a dorsal fin as sharp as a knife, the shy and timid golden foxface, the easy-to-keep but rather ugly ornate butterflyfish, the blue-and-purple-striped twinspot wrasse that sparkles...
Buyer: So what if they're pretty? Can you eat them?
Qin Ke: Then take a look at these. Scallops you can steam or roast, sea cucumbers packed with nutrients, sea urchins covered in spines, a huge lobster waving its claws, king crabs that can walk sideways across the sea floor, and electric eels that can light up a bulb...
Qin Ke finds a ceramic vase in a shipwreck on the seabed and plans to sell it on the black market.
Just as she and the buyer reach an agreement and she takes out the vase, the buyer pulls out a pair of cold steel handcuffs and locks them around her wrists.
The buyer, Gu Yan, stares at her coldly and says, “You are suspected of illegal trading. Come with us.”
Qin Ke: ...I picked it up while scavenging.
Later, he secretly follows Qin Ke, hoping to uncover the truth, only to see her jump into the sea to kill herself...
A story about an interstellar police officer and an orphan among the stars.
