Xu Xingchen hugged and said goodbye to all the ship girls, turned around and prepared to produce a few sets of combat equipment, put them in their own space for later use, and was preparing to replace them for trial sailing at sea.

It turned out that two scientific research ship girls stayed, namely Yuanwang 7 and Peace Ark.

Xu Xingchen knew that most of the two had something to do, so he temporarily suppressed his idea of ​​going to sea to test, put away his battle suit and asked back:

"What's wrong with Sister Qi, Peace, do you have anything to discuss with me?"

Yuanwang No. 7 did not answer immediately, but looked at the Peace Ark beside him.

Peace Ark coughed gently, as if it was brewing emotions, and then he said tentatively:

"We have a project that we want the Commander, Chaoge, and Black Fish to work together to make an observation and test subject."

Seeing that these two ship girls were serious, Xu Xingchen became serious:

"After saying that, what should I test? Special weapons and equipment? Need the three of us together?"

Peace Ark shook his head calmly:

"It's not weapons and equipment, but biology research."

Xu Xingchen was stunned and spread his hands blankly and said:

"Biology? What biology do I know? You have to look for Neptune for this. She has been tossing big rabbits, big lizards and so on the moon..."

Peace Ark nodded and said:

"Yes, in biology, we can only help the commander. We are not asking the commander to help with research, but preparing to study the commander himself."

Xu Xingchen opened his mouth, thinking that he had no intention of Peace Ark, so he nodded slowly and said:

"Okay, what do you want to study? Do you need to take blood and observe? Do you want a sample of skin, hair, saliva?

"I personally feel that the main difference between my current physical condition and the final genetic adjustment is on the eyes.

"Then it's more relaxed and flexible in the body, and there are no other obvious differences...

"No, there are Black Fish and Chaoge? Why do you want them?"

Xu Xingchen talked about his situation with a hammer from the east and a hammer from the west, and then quickly realized that he might have thought it was wrong, because the object of Peace Ark was not just himself.

As expected, Peace Ark tried to tighten his face and explained as calmly as possible:

"The direction we need to study is to determine whether there is still reproductive isolation between you and the ship girl after the final adjustment, so the ship girl must cooperate with you..."

Xu Xingchen immediately opened his mouth wide and finally understood completely that he wanted to study how to create life...

These two guys are too big of an idea. The key is how to carry out such a thing? How should we cooperate with you? You can't demonstrate the human creation activity on the spot, right?

When Xu Xingchen was shocked and confused, Peace Ark no longer made any concealment and directly expressed his own ideas:

"The physical structure of ship girls is not essentially different from that of human women. The only difference is that they will not ovulate periodically like human women.

"So, when the former ship girl was with the commander, she would not have any descendants. This is of course a de facto reproductive isolation.

"From this initially, we determined that the ship girl should not be born with fertility, and could only be obtained through the construction of the soul core, or generated by the condensation of deep-sea energy.

"But now the situation has changed, the deep sea has been arrested and entered a batch transformation process, and the ship girl world has lost its core soul output.

"The total number of soul cores has been fixed. After all the remaining soul cores are used up, there will be no new ship girl born.

"Although the battle suit design can be added freely, the product is just a battle suit rabbit. To generate the exclusive core of the ship girl, corresponding historical plans are required, and this is also limiting.

"At the same time, although there are still sporadic new and deep seas in the ocean, the speed of this birth has quickly dropped to nearly zero in the past year.

"That is to say, after the ship girl had a full armistice with the deep sea and no deep sea was eliminated, the new deep sea also became fewer, and it was even about to stop completely.

"We have reason to believe that only the continuous death of the deep sea will lead to a new deep sea birth, so the total number of deep seas is also limited.

"In this way, the total number of deep seas has been determined, the total number of ship girls has also been determined, and the total number of our entire ethnic group has become a fixed value.

"That is, according to all known information, our species cannot reproduce independently, or even completely, and its number cannot continue to increase.

"If the total population is locked, then the upper limit of civilization development will be locked at the same time. Such a species can be said to be incomplete and abnormal.

"Even if we control more technology and transform more planets, there are no more ship girls to use and control them. They can only make wedding dresses for other races.

“I think our creators should not limit us to this clear and narrow scope.

"Even the goal of the creator, who has lost the ship girl as a tool for the expansion of human civilization, cannot limit our population so clearly.

"So, there are likely to be another solution to this matter, a way to increase our population.

"And this method is likely to be in the commander, the commander who has undergone transformation, completes the gender of our population.

"If the commander and the ship girl can reproduce new ship girl, then all problems will be solved."

Xu Xingchen fully understood when he heard this. This is indeed a very serious matter. If the population cannot be increased, then the development of civilization will be impossible.

Species that lock in the total population, even if they are vassals of other species, may not be qualified, because the other party's population will continue to grow and they cannot keep up with each other.

Xu Xingchen actually had a sense of crisis in this aspect, but he didn't take it too seriously because the "creators" did not completely disappear.

"They" leave themselves to guide the task. After completing the task, they can obtain various new technologies through the system, which may include methods to increase the number of ship girls.

The current planetary environment transformation mission is obviously an important node for population expansion. After all, with a new territory, there must be populations occupied and lived in the past.

So Xu Xingchen suspected that after this task is completed, there may be related content in the technology that can be unlocked.

Even if there is no, most of the technologies related to the design and manufacturing of the ship girl themselves will appear in subsequent tasks and technology unlocking.

The ship girl is obviously a life created, and the related technologies that make them obviously exist in the "creator" technology library, and she is likely to gradually obtain these technologies.

For example, the manufacturing technology of the soul core, the operating principle of the ship girl's body, and even the transformation technology of intermediate matter.

The creators can make the ship girl come from scratch. After they have mastered their inheritance corresponding technology, it should be no difficulty to imitate it, right?

So Xu Xingchen himself did not care too much about this matter, but the sense of crisis among scientific research ship girls played a role.

Xu Xingchen thought this was a good thing, but there was no need to make them worry so much, so Xu Xingchen talked about his thoughts with the ship girls such as Peace Ark, Yuanwang 7.

When talking to his ship girl, Xu Xingchen basically didn't hide it. He said directly about the tasks left by the creators and the tasks that will be unlocked by technology.

After listening, Peace Ark and Yuanwang 7 were obviously relieved, and the seniors did not give up on themselves.

Xu Xingchen looked at the reactions of the two ship ladies, then smiled and spread his hands and said:

"So, don't bother me now, right? I always feel a little weird about how to reproduce..."

Yuanwang 7 looked at the Peace Ark, and Peace Ark shook his head gently and said:

"I think research is still necessary, at least let's check the commander, Black Fish, Chaoge your bodies and confirm whether our guess is correct."

Gu Yan

Xu Xingchen was stunned:

"What guess?"

After the Peace Ark relaxed, the common smile returned to his face:

"Ovulation behavior is ultimately controlled by hormones, and hormone secretion is likely to be affected by the outside world, such as the existence of males.

"So we suspect that the ship girl may not be infertile, but is not activated by males, such as the presence of the commander.

"So we now want to confirm whether Chaoge and Black Fish who are with you have similar ovulation after your life is transformed."

Xu Xingchen basically understood, and then subconsciously turned to look at Chaoge and Heiyu. The two of them also understood completely, but the reactions between the two were very different.

Chaoge was a little unnatural, standing there with his mouth slightly open, with an expression of wanting to speak but stopping.

Black Fish, however, blushed and lowered her head, looking particularly shy, but Xu Xingchen knew that this guy was probably doing it on purpose and was completely used to it.

Xu Xingchen brewed for a few seconds and looked at the Peace Ark again:

"How do you check? Let's cooperate as much as possible..."

"Commander wait..." Peace Ark was obviously ready and immediately unfolded its ship, with a bunch of monitoring tools on it, "Start with... the black fish."

Peace Ark is familiar with the personalities of Black Fish and Chaoge, and thinks that Black Fish is better to cooperate with.

As expected, although Black Fish looked particularly shy, she almost obeyed the requirements of the doctor Peace Ark.

Cooperating with the peaceful inspection, Black Fish couldn't help asking:

"Will we have children? Will we bulge our belly like human females? Then what should we pay attention to? Diet... life..."

The Peace Ark was a little helpless by the black fish. If humans asked these questions, of course they could answer them with their mouths.

But after the other party was replaced by a ship girl, he had no idea at all, so of course he could not give an accurate answer.

I can only talk about things that human women need to pay attention to, but each paragraph specifically reminds her that this is the human situation, and the ship girl is probably not like this.

Fortunately, Black Fish just instinctively wanted to ask. She didn't care much about the answers to these questions, and kept nodding...

Xu Xingchen and Chaoge were watching from the side, silent and in a complicated mood...

As the inspection of the black fish gradually deepened, Peace Ark's expression suddenly became a little surprised. Although it quickly returned to normal, Yuanwang 7 still noticed it.

However, Sister Qi said nothing and did not respond. She just continued to keep an eye on the inspection process.

After the final project was completed, Xu Xingchen asked like his family:

"Peace, have you discovered something?"
To be continued...
