As mentioned earlier, Nesta and Thicktooth are now using giant trees to conduct research on their developmental environment, and the trees have grown related results - ovoids.

Of these eggs, two are real eggs, born to small and medium-sized poultry of the tribe;

The remaining 7 are the result of ovitivation of moose and wolf embryos.

This is a controlled test to observe the effects of changes in energy content in the breeding environment;

Nesta made a series of observations by combining eggs, embryos, and plant fruits, and incubating the subject with intracellular fluid filled with energetic substances extracted from cave wolves.

And today, just as Nesta's thick teeth were looking at the nine 'eggs' with joy or sorrow, one of the eggs on the side crackled and shattered, and the wet and fluffy 'chicken' inside immediately 'fell off'.

And the two witch doctors seem to have been prepared, and under this 'fruit', there happens to be a soft carrier at this time;

And because the vines at this time have almost extended to the surface, the little 'chicken' did not fall to death, but fanned his little wings and looked full of vitality.

It has almost all the elements of a normal 'chicken' cub, and is even much larger than its normal sibling when they were born.

Nesta stooped down and held it in his hand, taking a closer look at its physical features;

The conclusion is that this is an older 'chicken', which is not fundamentally different from its domesticated fathers and ancestors in the tribe.

"It's not a failure, this thing doesn't have any potential in the first place, and if it can get so big, it's already a positive reaction." Nesta said to Rough Fang.

"Well, it's mainly about the changes in the moose and wolf embryos.... Judging from the current situation alone, the result should be good, but the conditions seem to be a bit harsh. ”

Since this is not the form of a half-tree troll, the rhythm of the thick teeth speaking is quite normal;

He handed Nesta the 'Observation Record' in his hand, and took the chick in front of him, and began to observe and explore further.

The thick teeth started with an ultrasonic detection technique, and almost 'looked' the 'chicken's whole body' all over before he spoke,

"The bone density is normal, the muscle density is normal, and the brain domain still hasn't changed.... It's just getting bigger. ”

"Well, I'll just say it..... It is estimated that another chicken egg is also about to be born. At least judging from the current observations, it should be very similar to this little guy. Nesta flipped through the notebook in her hand and replied with her thick teeth.

"Let's take a look at the results of the breeding, wouldn't it be nice if we could pass on this large body shape to the next generation? At least more meat is produced. Rough Tooth nodded, then said uncertainly.

"That's hard to say..... If there is no essential change in 'energy', then in the absence of a corresponding breeding environment, I estimate that the next generation will still be what it should be; In terms of 'meat production', it is estimated that it is not expected. Unless..... Unless we can really toss a 'Warcraft chicken' in the future, it is possible to increase production. ”

"That's right.... However, if the speculation you said is true, then it is possible that the descendants between you and Azhara will be different from ordinary people from birth, right? I guess it's possible that Fangs and I are likely, but it shouldn't be as stable as you and Azhara... By the way, why haven't you moved for so long? Is it because it will affect the gestation after advancement? ”

By the time he said the last sentence, the thick teeth had already changed slightly.

If it was really the reason he had guessed, it would not be good news for the tribe.....

Even the research they are currently working on is beginning to feel strong resistance because of their own speculation.....

The already small number of tribes can't afford to suffer more blows in pursuit of a 'few elite units' - this is the 'population' concept that Rough Fang holds at this time.

"It's not. The impact may be there, but it shouldn't be so complete; As for the more specific situation, it will depend on our current research to confirm ....."

In this regard, Nesta is really unable to make an accurate judgment right now.

Because of the scarcity of observation targets, this thing is not possible to study at all for the time being....

But if we just look at the results of him and Aishara, it is at least certain that there should be no complete loss of fertility.

Although, Aisara's 'ovulation cycle' did have a corresponding lengthening; But correspondingly, the 'sitting egg cycle' has also increased.

This means that the eggs conceived by Eshara are able to remain active in the abdominal cavity for a longer period of time;

So this comes and goes, whether fertility has increased or decreased.... It's really hard to say.

But at least after hearing this conclusion, Roughtooth's face recovered somewhat, and then he turned to ask,

"Then why hasn't Azhara been pregnant?"

"Uh...."

Nesta didn't want to talk about this issue that was a bit too private, but on second thought, it was hard to say that it was 'privacy' given the position he and Azhara were in right now.

So, after a moment of silence, he decided to tell the truth.....

"We just don't want children for the time being.... Whether it's fighting or researching, the effects of Aishara's pregnancy are a little too great; Also, I didn't think about what to do after I had a baby......"

Aishara's reason is reasonable, as the tribe's highest-end combat power and research force, she does have a lot of scruples when she is pregnant;

But Nesta's reason made Rough Tooth a little incomprehensible, and after some thought, he had a guess about Mohu, and opened his mouth to confirm,

"Are you still thinking about 'family'? Want to raise your own kids? ”

"Alas.... It's quite hesitant.,Emotionally speaking, I want to raise myself.,But at the same time there are more scruples.... So every time you come to the last minute, you have to pull out... Damn, why am I telling you this, work, work! ”

"Haha....." Roughtooth laughed for a moment as Nesta said half of what he said, before shaking his head and continuing,

"You have been different from us since you were a child.... I used to be looking for my mother, but now even the non-existent 'child', you can have feelings for some reason, I really can't figure it out..."

Nesta snorted, not quite wanting to continue the discussion.

Because in any case, the question ultimately points to 'crossing', to 'the influence of the concept of past lives";

It can be said that this is the biggest secret of his life....

"Okay, get back to work, and let the rest take its course, maybe I'll figure it out one day."

With that, he looked down and looked at the record carefully.

Seeing this, Rough Tooth didn't continue to ask, and also focused on the matter at hand.

~~~

In addition to the 'chicken eggs', among the remaining seven eggs, there are three groups of wolf embryos and three groups of moose embryos;

When connecting with the giant tree, they are marked according to the initial state according to the three gestational age stages: "fertilized egg", "early fetal stage", and "second foetal stage".

At the beginning, Nesta wanted to use it as a research target, but he had long since been removed from the original "focused observation" goal due to "potential", "reproducibility" and other reasons;

As a result, the tree now bears a fruit that corresponds to a large animal, and its contribution to research is dispensable.

[To tell the truth, I've been chasing more with reading books recently, switching sources, and reading aloud with more timbre,.. Both Android and Apple are available. 】

The notebook contains a detailed account of the observations at each stage, and even an approximate estimate of the time when they 'broke the shell'.

Among them, the two columns of chicken eggs clearly read, "Not much has changed....", which is a conclusion that has been reached long before today;

Because of this, when one of the two witch doctors broke the shell before, they did not show emotions such as "surprise", "disappointment", "joy", etc.

Nesta's voice rang out again at this point, and he concluded,

"I see, the second egg is expected to break through the shell in three days, and it is really a stupid choice to keep the original hard egg;"

"Moose eggs are born ten days later, one month later, three months later.... After 10 days, the error should not be large, but there may be some stunting; ”

"As for the one in a month, they are all dying now, and they may not survive until birth; Three months later, this...."

"This error can be a bit big, and the things in it don't look like a normal moose anymore..... Roughtoothed Witch Doctor, let's take Moose Two out before it dies.... Number three should surprise us a bit. ”

"Agreed, what about wolf embryos? No. 2 feels a little reluctant and may not be able to hold on, so do you have to take it out? ”

"Wolf Two.... Keep an eye on it, and keep it until the moment it really dies... It feels a little different from the Moose II situation. ”

During this period of experiments, there was a clear difference between oviparity and viviparity.

In the case of the 'chicken' eggs, no matter how Nesta combined them with the giant tree at that time, the embryos inside did not show a 'survival' dilemma.

But when it comes to viviparous moose and wolves, it's different.

At the time of the union, the two "No. 1 eggs" with the largest gestational age, although they successfully survived, they were even at the moment of birth.

However, from the perspective of magical observation, the changes they produce in the high-energy environment are the least significant among the control groups;

Even the small conclusion of 'getting bigger' is quite reluctantly defined.

At the time of connection, the two No. 2 eggs in the middle of the 'gestational age' are simply 'dying' at this time, and they may not be able to survive the moment the 'eggs' are broken.

On the contrary, the two embryos with the smallest gestational age at the time of connection, which were transferred into the 'fruit' not long after becoming fertilized eggs, are the group that now seem to be the most likely to achieve benign results.

However, the conclusion that they will be produced in three months is full of uncertainty.

The so-called 'after three months' is really just an estimate based on the gestation time under natural conditions;

If a more accurate calculation is made from the embryo's own forming condition, then the egg breaking time will most likely have to be pushed back for a long time.

From the observations of the now limited observation group, it can be concluded that:

No matter what time period the oviparous embryo is combined with the tree, the embryo itself can grow without damage; Viviparous embryos can only be transferred if they are fertilized in the early stage and in the middle and late stages when the fetus is basically matured.

Those with gestational age in between the two have the possibility of fetal death.

This gap between oviparity and viviparity is estimated to be caused by differences in fetal development patterns.

Specifically, the oviparous species has all the material in its original egg to support the development and maturation of the embryo;

However, because the viviparous species should have an umbilical cord and placenta connection with the mother, after the transfer of the tree, it loses this connection with the mother.

Although the witch doctors have mimicked the placental structure in the 'fruit' as much as possible, and turned it into a place of material exchange between the fetus and the tree;

But this kind of 'placenta', which can even be said to be shoddy, does not seem to fully simulate all the functions of the original placenta;

In addition, the nutrients that giant trees can provide are also different from those of the mother, so they cannot fully support the normal development of the fetus, which leads to the lack of vitality of middle-aged embryos.

And the initial fertilized egg is a little special...

I don't know if it was due to the effect of the diluted intracellular fluid provided by the giant tree, but from the moment it began to develop, it took a different path from natural conception;

Although they also face the same situation as middle-aged eggs in terms of nutrition and respiration;

However, because the environment in which he grew up was changed at the beginning, he took the initiative to adapt and make trade-offs during development.

As a result, while the embryo grows slowly, the biological essence is approaching the direction of the higher individuals in the group.

For example, the shape of the moose No. 3 can already be seen at this time in the shape of the moose population, the preference of the sub-leader of the moose population;

As for the wolf No. 3 embryo, although there is no significant change in appearance, there is a 'shadow' in the brain domain during ultrasound detection, and its location is just the area where the magic crystal is generated, and it is obviously developing in the direction of the demon wolf.

It is worth mentioning that this kind of suspected magic crystal induction is actually observed on the Wolf No. 2 embryo, which is not very certain;

Although it is not as obvious as Wolf Three, it also makes Nesta wonder if this guy has the possibility of advancement, so he said earlier that he should let it grow as much as possible.

This is probably the general situation of the 'dendritic transfer study', and although it is still a little waiting before all the results are verified, it seems that the possibilities of the future have already ushered in the dawn.

As a result, Nesta and the witch doctors, such as Roughfang, and Azhara who occasionally came to help, spent the time following on the transformation of the giant tree itself as much as possible;

Thanks to their joint efforts, the vines used for 'embryonic union' are growing slowly but quite resolutely.

From nine to twelve, to fifteen.....

As a result, more and more 'samples' are also being transferred one after another, and the witch doctors, led by Nesta, want to find a safe way for future troll experiments as much as possible.

……

On the other hand, due to the continuous construction of hydroelectric factories, the factories that were originally built in the city have also moved to the outside of the city little by little.

In particular, the basic parts factories that need strong and stable power and need a steady stream of production have been relocated in just one month with the initiative of the witch doctors.

After that, due to the trouble of parts transfer, even the assembly plant, which did not have a very urgent need for power, followed suit.

Because of the renewal of the driving force, a large number of trolls who were originally engaged in the "power post" have been liberated from boring work;

Together with the 'engineers', they prepared for the construction of a new factory.

These production units, which can be increased immediately, combined with the fact that they no longer need to consider the physical fitness of the 'power post' troll, have a tendency to pull the 'industrial' production capacity of each sub-base upward.

This change, first of all, has had a considerable impact on the construction sites on the front line, and the supply of various construction machinery has increased a lot;

Moreover, with the large-scale supply of semi-finished products 'wood, stone and concrete', the construction speed of the roadbed is also advancing by leaps and bounds like a hormone;

The laying of the track, which has been dragged down by the roadbed, has naturally accelerated the progress because there is no delay in the former.

Originally, it was expected that there would be 2-3 months before the final connection of the Cave Base to the Second Base of the Orbital Line, but after a month and a half had passed, it was already not far from a successful 'rendezvous'.

……

At the construction front, which is more than 320 kilometers away from the cave base and more than 170 kilometers away from the No. 2 sub-base, the pioneer production teams of the two bases are busy with their respective work in the assigned road sections.

Because in the middle of the project, there was feedback from the base that the logging operation was still carried out uniformly.

So at that time, the cave base gathered most of the production team and carried out a collective logging operation, clearing a large area of treeless belt at one time.

As a result, the logging trucks have largely withdrawn from the first line of rail engineering and have begun to carve out farmland near the city.

At the forefront of the cave base, there are two concrete mixer trucks roaring at this time; Tons of finished concrete are loaded into the hunched drum behind it, ready to fill the foundation.

The foundation is about 1 meter deep, and after the rough shape is excavated with an excavator, the corners are repaired by hand, then smoothed with concrete, and then steel and wood strips are used to build a three-dimensional grid-like structure.

Finally, the concrete mixer truck will pour fluid concrete into the grid to completely fill the entire tunnel.

After weathering, the concrete will cooperate with the steel and wood strips inside to form a dense base layer, and the sleepers and rails are laid on this foundation.

The method of building the track in this way was obtained by the witch doctors after repeated verification in the first few hundred meters of the road.

Although the construction process will be quite cumbersome and time-consuming, the follow-up maintenance is relatively easier, so as not to say that you have to have a major rework every once in a while.

And the cutting-edge construction site that I am looking at now happens to be in charge of Isa's production team.

At this time, Issa is driving the construction truck to the farthest end of the construction site, preparing to extend the excavation work further;

And his teammates, some of them are working in the tunnel, and some of them are repeatedly stepping on the pedals in the car to prevent the concrete from solidifying in the drum, so that the inside of the drum behind them is always in motion.

Aisa drove the construction truck out of the driver's seat for some distance, moved to the side control post, and began to urge the digging arm in front of him.

Because the tribe's engineering vehicles use 'troll power', unlike the earth in Nesta's previous life, the biggest source of noise for these engineering vehicles is only the sound of various gears in the power box engaging and bearings turning;

Coupled with the application of lubricating oil, its impact on the ears is not very serious.

In the midst of these orderly and distinctive sounds, Issa's sensitive hearing was not disturbed too much, so he faintly heard a sound farther ahead, which seemed to be almost indistinguishable from the construction site behind him.

"Captain!" He stopped manipulating the machine, turned around and shouted behind him.

"What's wrong?"

"I'm like... Hearing... Point Special: Sound! ”

Since the captain and the rest of the team were next to each other, there were two mixer trucks that were always working at this time, and the sound was actually a little noisier than where Isa was in front of him.

Therefore, the captain and vice-captain here could not hear the voice described by Issa at all.

"Why don't you go and see? What the hell did that guy hear. ”

In addition to supervising the project, the captain, who is also responsible for the task of security vigilance, said to the deputy captain.

The vice-captain's face was also a little solemn, he nodded steadily, jumped out of the foundation pit in three or two steps, and ran to the far end where Isa was.

When the vice-captain arrived next to Aisa, he listened attentively and heard something different;

Even since Eisa had stopped driving the digging arm by this time, the sound was even clearer than before.

"Like a construction site? But we should be on the front line.... Wait, could it be the vanguard of Base 2? ”

The solemn look on the vice-captain's face disappeared in an instant, and he turned to show some excitement and anticipation.

He commanded Issa, "Wait a minute, I'll take a look." ”

Then, the vice-captain gestured in the direction of the captain behind him from a distance;

He passed on his meaning to the captain, who had been keeping an eye on this side, and after getting his promise, he ran over there.

~~~~~

When the cave base is in full swing, the second sub-base located in the nearest east is actually not far behind.

At the forefront of the construction site, a construction team is also in full swing at this time.

This team is also mixed, its captain and vice-captain are all from the headquarters, and the other eight are outsiders.

The captain's name is Quinates, and before the adaptation, she was actually the captain of the original hunting team;

For some special reasons, Quinates was not 'promoted', but the team members under her command during the previous hunting captain period basically became the captains and vice-captains of their respective teams because of the reorganization of the production team.

I don't know if it's because of a coincidence, or because of the 'evil' taste of the witch doctors;

On the front construction site of the cave base, the captain and vice-captain of the team where Isa is located coincidentally are the members of the team under the command of Kunates...
