One day, there was a little mermaid who fell in love with the prince.

So she went and made a deal with the witch and got the witch to turn her into a human form.

Since then, she has assumed the pseudonym Xiaoyu, and has become good friends with the prince as a human being, and has also lived in the palace.

The prince admires Xiaoyu very much, likes this kind-hearted and beautiful girl, and likes to take her out to play.

Despite the pain of every step she took, she happily traveled with the prince.

Xiaoyu is satisfied, and for her, it is enough happiness to see the prince.

But the good times did not last long, and the prince fell ill, and he was sick and weak.

The sick prince could only be stuffed in the house.

Doctors from all over the kingdom came, but no one could find out what was wrong with the prince.

Even the oldest imperial physician in the palace only said that the prince was in good health, although his limbs were weak, and he had never seen such a strange thing.

But the little fish knows.

Xiaoyu is a mermaid after all, and she has seen things outside of human medicine.

There is magic in the world, and there are curses.

Xiaoyu was very worried about the prince, so he secretly found the witch back then and asked her for help.

The witch said that the curse was fatal, and that the prince would become weaker and weaker, and then die.

If you want to be lifted, you can only exchange one life for another, and if you want the prince to live, you have to die for him.

Xiaoyu didn't hesitate much, saying that as long as he could save the prince, he could do anything.

The witch was skeptical, and said "Have you thought about it, is he worth it for you to do such a thing?"

Xiao Yu nodded firmly.

The witch said, "Then you give him this medicine to eat, and the moment he drinks it, it is the moment you disappear."

You will become foam, dissipating into the air as if it had never existed.

Xiao Yu smiled when she took the medicine, she knew that the prince was saved.

The wizard who saw this scene sighed and left.

Xiao Yu quickly poured the medicine into a glass of water, walked to the prince's house, and secretly put the glass on the table.

The prince was very enthusiastic when he saw her coming, and said that he had been bored in the palace recently? It's been a long time since I've hung out with you.

Xiaoyu said, of course it's boring, you have to get healthy quickly, so that you miss the days when I went to play with you.

Then the prince said, "Then when I am healed, let us depart."

Xiaoyu bit her lip and said okay.

But the prince could never have imagined that some promises were destined to be missed, and that they would never have that day again.

So the prince said, but there is no hurry, I have to get married first.

Xiaoyu said, get married?

The prince sighed and said that he had been preparing for a while, and if he hadn't been sick, he might have done it long ago.

The prince said with a little hesitation, because of the illness that has dragged on until now, and she has not had time to propose, but she should agree, my ring is ready, and I will give it to her when I go to propose.

The prince smiled at Xiaoyu and said, If it goes well, please come and attend when the time comes, and I will find a very beautiful castle to hold the wedding.

Xiao Yu nodded reluctantly, feeling very uncomfortable.

But then I thought about it, it was okay, the prince was accompanied by his bride, and he should not notice that he had disappeared.

That way everyone will be happy.

So Xiaoyu just said, the bride must be very beautiful.

The prince just said that it was not particularly pretty.

That was their last conversation.

That night, the prince woke up from thirst, saw the water on the table, drank it, and instantly regained his strength, and came out of the room, and was cured.

The next morning, he took the ring and searched for his bride, but found that he could not find it anyway.

Xiaoyu is no longer in the palace.

No one ever saw the little fish again.

No one knows her true identity.

The little fish disappeared as if it had never existed.

They didn't care, they were busy celebrating the prince's health.

Only the prince remembered her, the ring that didn't give away, and the proposal that he didn't have time to say.

Later, the only trace of this incident in history is that the old lady asked the prince once how the disease was cured.

The prince said that because he drank a glass of water, the water was very strange, and he didn't know how long it had been on the table, but when he picked it up, it was still warm.

So the old lady wrote it down in his medical writings.

It is also emphasized that when you are not feeling well, you must drink plenty of hot water.
