Zhou Zekai, who swam into the depths of darkness, felt very strange when he experienced his current body with great care.

In this world, the relationship between mermaids and humans is like the relationship between hunters and hunted preys. It is just from the prey at the beginning, and the change in identity later makes people feel strange.

In the eyes of humans, mermaids are mysterious and strange, full of all kinds of fantasies, and have no IQ. They only know how to eat in the deep sea. They were finally caught. But how many people know that humans are also prey of mermaids. mermaids have already arrived ashore thousands of years ago. They hide among humans, and they are so easy to not let anyone discover it.

As for the physical state Zhou Zekai is in now, it is just because he has not yet fully evolved. A mermaid who has completely evolved can have human legs and is even more powerful than humans. And in the sea, a mermaid is also a well-deserved strong man!

This involves a very strange feature of mermaids, which is called estrus.

Generally speaking, animals do have estrus periods. The reason why humans are superior is that they think they are different from animals. However, humans do not know that mermaids do not have low IQ. On the contrary, mermaids have very high IQs and can reach a minimum IQ of more than 300 humans. It is because of this that they are better at hiding and not being discovered by humans.

However, these all need to be evolved at a deep level, and this evolution is called the estrus period.

The most important thing for humans to evolve from the earliest maternal society is that men become stronger, while mermaids are different. In a sense, mermaids are very possessive creatures. They will find the half they recognize before the estrus period, whether the other party is a mermaid or a human.

If a mermaid is, everyone will be happy. If it is a human, the other party will be gradually transformed into a new mermaid by a mermaid during the estrus period, and evolved in three months, and finally turned into a complete mermaid.

So... to a certain extent, mermaids have a long lifespan longer than humans. It is precisely because of this long that fish have learned to survive in the human world. They are carefully hiding themselves, but... some people are too frowning! They actually try to find the secret of immortality from mermaids.

After Zhou Zekai accepted all the inheritance memories of mermaids, he knew that mermaids had no secret of so-called immortality. Mermaids were originally much older than humans, and they should be at least about five hundred years. Moreover, the humans who were transformed into mermaids would have the same lifespan as them. For example, Zhou Zekai has lived for three hundred years now, and the fish may only be only two hundred years left. If he found a human during the estrus and transformed the other party, the other party would have two hundred years of life.

Just like a virus, if you want to live forever, you have to give up what they have always been. The most important thing is that in the eyes of mermaids, the objects they need to transform are always those young men or women. In other words, people over 40 years old don’t have this opportunity.

Of course, there is also an alternative in the inheritance of mermaids, the alternative queen called mermaids.

This meaning is very wonderful. It is different from the relationship between humans. The queen of the mermaid was born in the water. After being transformed, she will have a fiery red tail. The singing can make other mermaids obey her orders. The most important thing is that the birth of each fiery red mermaid is accompanied by various pains.

After all, during the estrus, some people will go ashore to find a partner, and the mermaid's parents will bring back humans, and more of the combination of two mermaids, and... unreasonable mass union.

The so-called fiery red mermaid was born under such circumstances. It has too many genes of other mermaids, which led to the sounds she made that made many mermaids obey her.

This is not a good thing. After all, mermaids are cruel after all. If they are directed to do what they are unwilling to do, they will only be torn to pieces by their fangs.

Zhou Zekai, who was floating in the water, recalled the mermaid's estrus period. When he thought about the time in the hall, he felt that things were not going well.

The estrus period of mermaids is consistent, all in July every year. Now, it is June 3rd outside, which means that there are more than twenty days left, and all mermaids in this institute will enter the estrus period!

And in a few days, the nightmare of the mermaids will begin, which is the process of gradually changing from tail to legs. Zhou Zekai knew that the mermaids hidden between them had come to save them, and planned to come before the estrus period, but it was too late. In the mouth of the wisher, he knew that when these mermaids arrived, the institute had become hell, because the mermaids began to kill heavily after estrus.

There is no way, after being in heat, he mates and has to protect his partner. Faced with such crazy attacks, the mermaids naturally have to start killing.

Just as Zhou Zekai was floating, he suddenly felt a pain in his body and actually bumped into something similar to a wall, which made him stunned. The mermaid had very good vision in the deep sea, but even so, he could not see the glass.

Zhou Zekai gently stroked the glass and saw his hands. No, maybe it should be said to be webbed claws. The webbed claws looked a little light blue. The long-term blood draw made him a little malnourished. If he could go out, he should hunt a whale to eat.

Every mermaid here feeds a daily feed of 100 pounds of fish, but in fact, mermaids do not need to eat every day. As long as they hunt once and eat enough food, they will not eat for a month. For example, Zhou Zekai, he saw from his memory that he preyed on a blue whale and swallowed it into his stomach. Mermaids are much more cruel than humans imagined.

It is precisely because of this that Zhou Zekai appears to be seriously malnourished due to blood draw.

Just when Zhou Zekai was in a daze, he suddenly heard a song coming, and the song floated into Zhou Zekai's ears, but it turned into a nice voice of a man.

"A Kai, have you chosen the human beings who will spend the estrus together?"

The sound seemed to be coming from a very far place, but it was very close. Just when Zhou Zekai was stunned, he saw a mermaid with a blue tail swimming in the dark behind the glass. The mermaid had the appearance of a European and American man. He looked at Zhou Zekai with a kind look.

"Yu..."

Uncontrollably, Zhou Zekai also made such a voice that humans could not understand at all. He knew that the name of the blue mermaid in front of him was Yu, which was chosen by his parents himself, because Yu's parents already had human legs and successfully concealed among humans.

In the situation that many people don’t know, there are many smart mermaids in this world that they can’t do. No matter which industry, there are already mermaids everywhere. Otherwise, humans and mermaids will not be hunted in the later stage.

Humans want to eat mermaids to get more life. Mermaids originally only need to eat meat, but under the provocation of humans, they also began to use eating human flesh to protest. In the history of mermaids, mermaids came ashore more than 5,000 years ago. Later, after everyone passed the estrus period, they had human legs, and more people got ashore. From the records of those mermaids, Zhou Zekai saw many smart people, but their identities changed and they became mermaids.

"I like that human named Mo Jingzhou. What about you? He said he likes Wei Xueqian."

When he said this, Yu's face was expressionless, his mouth was slightly open, and a nice voice emanated, which made Zhou Zekai understand the other party's origin. Yu, Gan, they all know each other among this generation of mermaids. As the estrus period is approaching, they must also deal with it. The best way is to find a human to go through the estrus period, so that they can grow legs.

And they are now in a cage, and the best way is to find this suitable human being separately.

"I like Fang Yating."

Zhou Zekai did not hesitate. If the final result had to be converted into a mermaid, then Zhou Zekai hoped that Fang Yating would not be forced to become a fiery red mermaid this time. He would rather the other party rely on him and become weak.

"Female?" Yu frowned, and then a sound wave came out.

“The female is very weak.”

For mermaids, choosing women is indeed a very risky thing.

For example, mermaids have no gender. They can be considered female or male, and can nurturing offspring by themselves. Therefore, after changing to humans, mermaids often give birth to children by themselves, which can maintain the purity of mermaid bloodline. The converted mermaids have no fertility function. Nearly a year ago, mermaids often choose estrus objects among mermaids, and fewer females.

First, because females are weak and prone to death.

The second is because for mermaids, males are more in line with their aesthetics.

"I'm fine." Zhou Zekai replied again, feeling that this headache-inducing estrus period was a bit scary. He didn't know if these mermaids would start killing again during the estrus period...

After hearing Zhou Zekai's words, Yu had no objection, and then he explained a few more words before wandering around. At this time, it was time for humans to eat. Although he didn't want to eat, he was very hungry.

Zhou Zekai soon saw a big fish swimming in the water. The fish was put in by the administrator. He easily reached out and grabbed it. He grabbed one. He frowned and put the fish in his mouth and took a bite. He felt a sweetness spreading in his mouth, which made Zhou Zekai's appetite expand and he quickly ate the batch of food.

He always needs to have the strength to get through the estrus period, otherwise, it would be bad if other mermaids come to rescue him and he is still a mermaid.

Researchers in the research room also felt that these mermaids have eaten too much recently. They have increased from the previous one to two hundred kilograms every day, but they still fell into the pool and disappeared.
