A long time later, people can now step out of their homes without any worries, and no longer need to cover their mouths and noses with masks or face masks to block the suffocating foul air.

One morning, there was a rapid knock on the door.

When Jiang Ze saw Ana Shen standing outside the door, he asked in confusion, “Brother, why are you here so early?”

Shen Yanhua didn't bother to explain too much, but just asked anxiously: "Is Xie Qi here? I have something urgent to find him!"

At this time, Xie Qi, who heard the noise outside, came over from the bathroom and asked with the same puzzled look on his face: "Brother, what do you want to talk to me about?"

Shen Yanhua: "Xie Qi, Li Mu seems to have some health problems. You are a mermaid, so you are more familiar with these things. Could you please go and help him take a look?"

Hearing this, Xie Qi and Jiang Ze looked at each other, and immediately followed Shen Yanhua to his room without saying a word.

As soon as they entered the room, they saw Li Mu sitting awkwardly on the bed, with her fishtail exposed under the quilt at the end of the bed.

Li Mu was supposed to be the most perfect mermaid fused with Xie Qi's genes. As long as his legs didn't touch the water, his tail would turn into legs. But at this moment, Li Mu couldn't maintain his human legs.

Shen Yanhua: "His legs can't be restored. Is he sick?"

This abnormal situation has never happened before. Could it be that the original transformation experiment left some imperceptible sequelae? Thinking of this, Shen Yanhua's heart became more and more hanging.

At this time, Xie Qi's eyes were also fixed on Li Mu, but his face showed an extremely strange expression.

I saw that he was frowning and a slight "hissing" sound came out of his mouth from time to time.

Seeing this scene, Li Mu and Shen Yanhua's hearts sank again.

Shen Yanhua couldn't wait to ask Xie Qi: "Is this serious? Is it dangerous?"

However, the only response they received was Xie Qi's involuntary, puzzled hissing sounds.

Even Jiang Ze, who was standing by, couldn't bear to watch it anymore. He stretched out his finger and gently poked Xie Qi.

Xie Qi, who was poked by Jiang Ze, finally calmed down. He then looked at Li Mu, then at Shen Yanhua, and asked, "Well, who... is the top?"

It's no wonder Xie Qi asked this. After all, Xie Qi always thought that Li Mu was the one in a dominant position, but from what he saw now, it seemed that he was on the wrong side.

As Xie Qi finished speaking, Shen Yanhua's face turned red. He stammered, "Why...why are you asking this all of a sudden?"

In contrast, Li Mu, who was sitting beside the bed, seemed quite calm and composed. He replied, "Him."

Xie Qi: "That's right, you're not sick, you just have an egg."

"Egg?!"

Ana Shen repeated the unfamiliar word with a confused look on his face.

Seeing this, Xie Qi continued to explain, "That's right, mermaids are hermaphrodites. This is normal. Mermaids can't transform into two legs while they're still laying eggs. It will be fine in a few days."

After successfully answering the questions in the two people's minds, Xie Qi winked at Jiang and secretly left, leaving Li Mu and Shen Yanhua still digesting the information they had just received.

However, after arriving at his room, Jiang Ze kept staring at Xie Qi's belly, and finally asked in confusion: "You can also hold an egg?"

When Xie Qi heard this, he hugged himself with his arms and said warily, "What do you want to do?"

Jiang Ze: "How about... we switch? I'll be on top?"

Xie Qi didn't expect that Jiang Ze would actually have such an idea. Xie Qi was so angry that he laughed and picked up Jiang Ze and walked towards the bed.

Then he leaned over and pressed on Jiang Ze, explaining, "That's not what bisexuality means. The first time you have sex, it will differentiate your characteristics. And my first time was when I pressed on yours, so it no longer has the function of kissing your balls."

After hearing Xie Qi's explanation, Jiang Ze responded with an expressionless "Oh", then pushed Xie Qi away without any reluctance and got out of bed with a neat movement.

Xie Qi looked at Jiang Ze's series of smooth movements with a look of astonishment, and couldn't help but complain: "No, I just didn't want you to press me, so you ignored me?"

Jiang Ze straightened his slightly messy clothes and responded without turning his head: "It's early in the morning, be good and don't make a fuss. Clean up and go downstairs to have breakfast."

Xie Qi sighed helplessly, pulled up his pants and fastened his belt, muttering, "You just left me alone after teasing me. You're not responsible at all. If I had let you press me just now, I guess you wouldn't want to go to dinner now..."

Time passed quietly, and the two eggs that Li Mu had carefully cared for finally hatched.

From one of the eggs, a delicate human baby slowly emerged, while from the other egg, a mermaid baby with a beautiful fish tail was born.

After they dried the little creature, the mermaid baby, which originally had a fish tail, had its tail transformed into legs. This mermaid baby became the world's first natural mermaid.

Fifty years later, the Earth has gradually regained its former vitality. The once turbid sea has become deep and azure again, the vast land is covered with green trees and lush grass, and the air is filled with a fresh and pleasant scent.

At the same time, the social status of mermaids has also undergone tremendous changes. They are no longer discriminated against as they were in the past.

There are even many humans who fall in love with mermaids and together give birth to the next generation, which symbolizes love and hope.

For same-sex couples, having a cute baby is undoubtedly a deep desire in the hearts of many people.

As this demand grows, mermaid transformation technology has gradually been improved and standardized. The technology has also become safer and more reliable, and people can choose whether to undergo transformation into a mermaid according to their own wishes.

However, the transformed mermaids could not restore their original legs. In order to promote the harmonious development between humans and mermaids, Xie Qi provided a drug and mass-produced it in society.

This potion allows the transformed mermaid to temporarily maintain its legs for a few hours.

The offspring of modified mermaids are divided into humans and natural mermaids.

Natural merpeople can switch freely between legs and a fish tail without the aid of any potions.

In most cases, the birth rate of natural mermaids is relatively low, so every natural mermaid is extremely precious.

Currently, there is only Xie Qi, the deep-sea mermaid.

Decades later, Jiang Ze passed away, and Xie Qi quietly vanished from public view. Thus, the last deep-sea mermaid disappeared from the world.

As the years passed and civilization evolved, the time came for humans, modified mermen, and the rare natural mermen.
