In the tenth year of their marriage, more and more mermaids began to come ashore. They controlled their supernatural powers and began to learn human knowledge.

Mermaids are peace-loving and are not afraid of war, but they never initiate war.

As time passed, humans no longer feared that mermaids would suddenly use their abilities to do bad things.

Of course, it is best for humans not to provoke mermaids. After all, mermaids are a very protective group.

In the fiftieth year, humans finally gave up trying to restore their high fertility from mermaids and instead began to manage the environment.

Human fertility continues to decline, mainly due to excessive environmental pollution, which affects human health.

If human life expectancy had not increased significantly in recent years, I am afraid that these fifty years would be enough to kill 90% of the human race.

Mermaids like places with good environments the most, so they help to control environmental pollution.

Coupled with the mermaid's special abilities, they can easily handle many things that are very troublesome for humans.

In the past fifty years, more and more mermaids have come ashore, and more and more mermaids have formed families with humans. However, there is a secret that humans still don't know.

That is the mermaid tribe's companionship contract, which allows them to share lifespans.

Because even though fifty years have passed, Bai Chi and Chu Yunxiao are still the only pair of lovers, a human and a mermaid, who have a partnership contract.

Because humans are so fickle in their emotions, the mermaids tacitly keep this secret.

And it turns out that this was indeed the right decision. It is almost impossible for humans to remain loyal to their partners forever.

If it really exists, it won’t be too late to sign a contract a hundred years later.

All the mermaids who came ashore were warned by the Mermaid King that they could be sad because of their loved ones, but they could not lose their lives for it.

The biggest change is probably that human women are beginning to tend to pursue mermaid males as partners.

In addition to the fact that almost all male mermaids are handsome, because of the union with a mermaid, both pregnancy and childbirth will become easier.

Mermaids' offspring are oviparous. The largest eggs are no larger than a fist, and the smallest may even be only as big as a finger.

However, the latter are mostly mermaids and the offspring of mermaids. This is why mermaids can lay hundreds of eggs at a time, but less than one in ten can successfully hatch and grow up.

When humans and mermen mate, the offspring are generally the former, and there are only two or three eggs at most, and sometimes only one egg.

Such fish eggs are healthier and easier to hatch, with a survival rate close to 100%.

As for whether the hatched one is a mermaid or a human, it depends on fate. Fortunately, Bai Chi has paid attention to the data in this regard, and the probability is that the ratio is 50-50.

In the first hundred years, the high priest and the mermaid king worked out a way to cancel the partnership contract, which could be done by the mermaid herself without any harm.

It was also from this time that mermaids and their human partners began to sign partnership contracts. As for those humans who had long been blacklisted by mermaids for betraying their lovers, they naturally regretted it, but unfortunately it was too late.

The person who had the biggest reaction to this incident was probably Chu Yunxiao.

She refused to let Bai Chi learn how to cancel the contract, as if she was afraid that one day she would wake up and be kicked out by her lover.

Bai Chi almost cursed and swore, but finally promised that he would never learn that thing. Only then did he successfully appease the person who went crazy every night and made trouble for no reason.

Of course, it is impossible not to learn. He is also curious. At most, he will just not let his partner know.

Bai Chi is confident that he can do this.
