It is extremely difficult to reproduce among different races, the fertility rate is quite low, and the chances of reproducing between different races are different.Even if two different species can produce offspring—for example, a mule on Earth is the offspring of a female horse and a jackass, but if it is a male horse and a female donkey, the genetic combination rate is negligibly low.

The interracial reproduction among intelligent creatures has to undergo the biggest test!

If the parents are creatures with uneven combat power, such as the mother's S-level and the father's only B-level, the fetus is likely to be absorbed by the mother as nutrition during pregnancy. Nutrients cause themselves to be absorbed, and fetuses that lose their mothers die too!

The fertility rate is appallingly low, but every hybrid born by chance is uniquely excellent...

For example, Bassong's father is a B-class human, and his mother is an S-class Zerg. Although his combat power rating is only in the same range as his father's, he has a survival physique that surpasses that of a human!

Now that the supplies are abundant, it is natural that they will not go hungry when nothing happens, but after a full meal, they can basically go without eating or drinking for a week, and they do not have the ferocious nature of the Zerg that is almost impossible to communicate with.

...But for everyone in the basement, the understanding of this point is limited to "interracial reproduction is a difficult thing."

"What's the matter, did I not speak clearly enough?"

After the conclusion was thrown out, the room fell into a strange silence, and Erland frowned and looked around.

Bassong's face was blank, and his dark pupils reflected the outline of the fluorescent lights in the basement, "So that's why you asked us to come here... and then?"

It is not surprising that the physical characteristics of the mixed blood show any appearance. Why did Erland insist that it is impossible?

Sighing, the mermaid doctor actually hates explaining things, he is not like the captain, he can enjoy bickering with others for a day when he has nothing to do... A-level humans are really naive to vent their remaining energy.

"The fog star people whose ancestors are aquatic animals have a very small body density, so they can float in the atmosphere of the parent star, and the swamp beast people... As you know, the weight of the same size is more than five times that of a human being, and it will sink in the water. bottom.” Erland selected several items on the floating screen to zoom in, “The two races with very different physiological structures, no matter how lucky they are, the chance of giving birth to offspring is less than 1%, not to mention inheriting the super strong predatory tentacles. The attacking organs of..."

Indeed, the tentacles of the Marsh Orcs and Mist Star are almost invincible individually!The fragile body is eliminated, and the flexible tentacles can make up for the slow movements of the marsh orcs... What if that hybrid did not go berserk in the school district, but appeared in large numbers on the battlefield?

Tyr's expression became heavy, sitting next to Erlan's right hand, looking at Lu Zhongxiao opposite: "My family has collected a lot of information on the fog star, even the purebred fog star's predatory tentacles are recessive genes, and they reproduce with the mother .In other words, as long as there is a mixed blood phenomenon, 100% will not grow this kind of thing..."

"Recessive?" Lu Zhongxiao thought for a while, and decided to focus on the result, "Anyway, I'm not a biology major, so your deduction process can be omitted. In short, it's impossible for that monster to have the characteristics of tentacles, right?"

Erland nodded, and directly called up the analysis data he had prepared. The screen has a 360-degree visual range, and you can see the above things from any position by the table: "I also took other situations into consideration during the calculation, such as gender. .It came to the conclusion that if the creature that attacked you was female, it would not be possible to inherit the tentacles."

"Ah, does it have anything to do with gender?" Viviane, the only female human present, was puzzled, holding her chin to study the professional-looking form.

There's more to explain...

Erland scratched his dark green hair in pain: "Although the parents of various mixed races have different information, on the whole, when the mother's combat effectiveness is stronger than the father's, the offspring are more likely to be born safely. If the child is still a female , equal to inheriting more mother's genes - so there is such a conclusion in the universe, mixed blood is already very good, and if a girl born to a high-strength mother, it represents the theoretical hybrid of the two races, the best status!"

Scanning the few people in front of him, he found that he was still thinking about those remarks. Erland gave an example and added: "For example, if Bassoon is a female, besides the rich emotions and relatively peaceful personality of human beings, there are also other things. The high-defense carapace that will be perfectly inherited from the mother is enough to cope with the uninterrupted cosmic radiation of the Zerg Planet, so there is no need to come to the earth to live."

"Hey, why do you always use me as an example!" Basong patted the table dissatisfied.

Erlan spread his hands indifferently: "It can't be helped, you are the only hybrid now. To sum up - even females can't grow predatory tentacles, let alone males. I have been monitoring the captain's health for the past few days I didn't pay attention to other things, until I saw the news reports on TV...Can't you really take me to see the dead body of the perpetrator?"

"It has been taken back by the relevant personnel long ago, and I have no way out, I can't even take you to see the corpse." Lu Zhongxiao said that he was powerless, and then thought about other ways, "Or try to snatch it late at night..."

"This is a crime!" Tyre immediately reminded.

Erlan gave up the idea, and said loosely, "It's fine if you don't see the corpse. Let me think about it... Even if the other party is a mixed race of two races, there is only one way to manipulate this kind of tentacles, which is external transplantation, and According to Till, all the tentacles of the Fog Star are connected to the central nervous system. After the captain destroyed the brainstem, the other party immediately stopped all attacks, which can also prove this...then the operation will only be performed in the 72 days before the berserk state appears. within hours."

Lu Zhongxiao has been listening carefully, and slightly raised his eyes to look at him: "...rejection reaction?"

"That's right." Erland nodded affirmatively, "It's equivalent to implanting organs that don't belong to us in the human body. People on earth will die within a few hours. Even the powerful bodies of swamp orcs can't bear it for too long. 72 hours is enough." It's the limit."

The members of the "alloy python" used to perform body modification surgery, but only replaced the original limbs with alloy bones and weapons. No one dared to transplant biological organs into themselves, which is enough to show that they are also afraid of rejection.

Lu Zhongxiao pursed his lips, raised his hand and stroked his chin in thought: "That's really interesting... Man-made monsters were dropped on the earth. This matter is inseparable from Wuxing's soft-bodied bugs."

The accident that happened that day, because he happened to be there, and with Tyre's help, except for the humans who were killed on the spot by the predatory tentacles, the rest of the poisoned and injured were sent to the hospital in time. According to the difference in physique, some people are still not awake, but Fortunately, there were no new deaths.

...But what if this artificially created biological weapon appeared in multiple places at the same time?

Earth's elite fighters are concentrated in space, and there are only basic defenses on land. In any case, it is impossible to deal with top-level combat creatures. The only way to solve the problem is to use high-destructive weapons to completely eliminate them from a distance—but correspondingly, the damage caused to buildings And environmental radiation, as well as follow-up processing work is not a small workload.

"Doctor, can I borrow your optical brain?"

When the whole room was silently thinking, Tyre's voice sounded.

After Erlan nodded, he accepted the control of the screen and quickly entered the data. A three-dimensional star field map was quickly formed with clear layers.

"The doctor explained that the appearance of that thing was not accidental or accidental, but a man-made weapon. As for me... maybe I can explain why such a weapon was made."

Lu Zhongxiao recovered from his thoughts, and the young man sitting opposite happened to be looking at him, and there was a tacit understanding of the same frequency of radio waves when they looked at each other.

I can probably guess what Tyr will say...

"First explain our clan's alliance plan. Apart from the people on Earth, the Mermaid Planet and the Bug Planet should be familiar with it." Tyre's blue eyes fell on Viviani, the only one who might not know about it.

The latter immediately raised his hand and spoke: "I'm not an ignorant captain, but I'm usually very concerned about space news! Isn't it an alliance project? It's similar to the United Nations and trade organizations in the past on Earth. Benefits. Although its own leading technology has to be shared with other planets, but also get more, generally speaking, the advantages outweigh the disadvantages of the alliance!"

A series of speeches accurately described the nature of the alliance.

Lu Zhongxiao frowned in dissatisfaction, "It's as if I never cared about the situation in the universe..."

The voice was a little guilty, after all, he really didn't care much.

"Actually, it's nothing. The captain actually has a good planning concept and is someone who can make a schedule." Tyre helped explain, but the smile was imperceptibly stiff.

Indeed, Lu Zhongxiao is a very planning person. When to get up and go to bed, and what to do in a day are all scheduled in advance. This habit should be influenced by the scientist's mother, such as the arrangement of "going out to buy things" that day, It was written in the log of the central system by Lu Zhongxiao as early as a week ago.

When he discovered this, Tyre himself was very surprised.

On the Wild Rose, there was a page-by-page plan written by the captain, and he accidentally glanced at it...

In early April, he robbed Star Field No. [-], and then went to repair behind the meteorite bunker.

In mid-April, if you are tired of drinking nutrient solution, grab some natural food.

In late April, focus on searching for local products in the distant star field and grab some.When encountering a spaceship on a long-distance voyage and having nothing to grab, sell the supplies at ten times the price, and no bargaining is allowed, and no postage is included.

——Although they all have criminal records, it can at least prove that Lu Zhongxiao is not a person with no plans... right?

"I remember Erlan's mermaid planet, and Basong's mother's Zerg are all allied with Saga planet, is that true?" Lu Zhongxiao was also trying to prove his strength, but his whole body was stiff, and he would bite his tongue if he spoke too fast.

Tyr nodded, affirming his statement: "Yes, most of the intelligent creatures in the Centaur Spiral Arm have united...except for Fog Star. The other party is neither willing to share their technology to join the alliance, nor does they want to see our strength grow , This is the biggest reason for the war. Since the initial war was lost, we must find a way to make up for the benefits elsewhere.”

"...So you came to Earth?" Lu Zhongxiao raised his eyebrows with an unhappy expression.

An alliance is a matter of participating in the internal affairs of the planet, and it will not bring about external wars at all.However, in the eyes of some races, "one's own strength has not increased" plus "others' strength has increased" is equivalent to "one's own backwardness"...Of course they will not sit idly by!

And the Mist Star has been a race that relies on plunder to maintain high consumption and reproduction since its birth.

"Earth is one of the most important planets in Orion's spiral arm. They may be worried that our race will send invitations to this place in the future, so they acted first..." Tyre, who has advanced in Earth language by leaps and bounds, used quite accurate adjectives.

Destroy the enemy before they succeed.It is not difficult for the people of the Mist Star to understand such a plan, and the earth issued regulations to eliminate the creatures of the Mist Star when they started the war, which has already secretly expressed their attitude.

"From the perspective of people on Earth, the situation is not serious enough, and remaining neutral is the best choice." Lu Zhongxiao looked at the star map and said, the planets divided by power showed different colors, "But now, someone It's forcing us to make a choice..."

Either advance or retreat, it is absolutely impossible to wait and see!

"Then boss, what do you want?" Bassong is not good at dealing with interplanetary politics, "I am a mixed race, and my identity is already very embarrassing. If the earth chooses to form an alliance with the fog star..."

Lu Zhongxiao turned his head: "I couldn't say it well before the hybrid berserk incident, but after that, the future choice is already obvious, right? We can all see the man-made attacks, those who recovered the corpses for research Don't scientists know anything?"
