Yun Jiao is a legendary mermaid who accidentally traveled to a small fishing village in the 1980s. Her beauty is still there, but her body has shrunk. The beautiful mermaid has become a white and soft baby with short arms and legs. Her fish tail has degenerated into legs, but it doesn’t matter, she can still breathe in the sea water and she doesn’t need to learn how to swim and dive. Her ability to cry and turn into pearls is gone, but it doesn’t matter, she can look for pearls in the sea. She is no longer a mermaid, but she is still the darling of the ocean. Going out to catch fish, others have worked hard but can’t find anything valuable. She took her brothers to pick up big yellow croaker, lobsters as long as their arms, and even the coconut snails they picked up bloomed expensive flames.

Due to an accident, Su Jiu, who died in the end of the world, traveled into the interstellar beast world and became the unwelcome second daughter of the Duke's Mansion.

Su Jiu: Isn't it better to live comfortably lying down? Why did I get such a fragile body after traveling through time! It's so expensive.

Worrying about how to get out of the predicament, the reborn eldest sister-Su Rui no longer wanted her childhood marriage to the commander and insisted on switching marriages with her

Su Rui: "I don't want to spend my whole life with a useless man!"

Su Jiu thought about it, Gu Lingce is good-looking, powerful and rich, can't have children, and will die early, a perfect marriage partner.

Without hesitation, she agreed.

After getting married, Su Jiu was looking forward to becoming a widow every minute so that she could inherit all her husband's property.

-Gu Lingce, the eldest prince of the empire, the strongest commander in the galaxy, is full of patriotism and believes that he has no mood for love.

The marriage was set, but the Duke's Mansion suddenly changed the bride.

Gu Lingce, who was forced to marry, thought about waiting for the one-year cooling-off period of the marriage to end so that he could divorce.

Until one day, Gu Lingce heard his little wife waiting to become a widow in her sleep, and laughed angrily, "Even if you die, you will still be mine!"
