When Levi handed over the "20 Primarchs of the Imperial Ultramarines and 19 Operations" to Iger, he had already given him instructions repeatedly.

Before the technology matures, it must not be put into clinical use.

He didn't want his soldiers to die meaninglessly on the experimental bench instead of dying on the battlefield.

But the Cavans, who were at the bottom of the food chain at that time, were not included in this list.

Because of their lack of intelligence and tendency to act instinctively, Cavans were not classified as intelligent creatures by Livy.

Even though they gradually developed high obedience and a certain degree of intelligence under Calvin's training, and began to get involved in the express delivery and food delivery industries, it could only be regarded as the result of training.

However, at that time, the rat people with higher 'value' had been screened out and obtained certain 'rat' rights, and were no longer reduced to a source of food and various raw materials.

Therefore, the Cavans who failed to embody this "value" became the guinea pigs used as materials for transformation experiments in the Eagle Biochemical Laboratory after being suppliers of food and fur.

And the Caverns ratman brother in front of him who knocked him away is the product of this experiment.

Based on Levi's visual inspection, it should have undergone at least five surgeries: [Second Heart], [Bone Strengthening Organ], [Muscle Strengthening Organ], [Hematopoietic Organ Reconstruction] and [Third Lung].

First of all, without the growth hormone provided by the [Muscle Strengthening Organ], Cavans would not be able to grow to such a size that is almost several times larger than that of similar species.

And such a body of noble muscles, if there is no [bone strengthening organ] to enhance the strength of the bones, it will be a pile of rotten meat that cannot stand up.

Bone-strengthening organs monitor and secrete hormones that affect epiphyseal healing and bone ossification.

At the same time, the original version of the special bioengineered hormone can promote bone tissue to absorb the ceramic compounds added to the modifier's ration.

Two years after implantation, this will cause significant strengthening of the long bones and extreme ossification of the thorax.

Among them, the ribs will grow into bone plates, which overlap and overlap each other, blending into one body, and overall increase the size of the recipient's bones.

I wonder if Igor and his colleagues can invent similar hormones, otherwise the survivability of the modified Ultramarines will be compromised.

Well, with such a strong body, it naturally needs a strong oxygen supply system to supply energy.

Therefore, [the second heart], [the third lung], and [rebuilding hematopoietic organs] have become necessary.

The second heart can not only speed up the blood supply, but also maintain complete physiological functions when the recipient's original heart is damaged.

The third lung is essentially a gray tubular organ through which blood flows from blood vessels grafted to the recipient's pulmonary system, and air is drawn in through the sphincter muscles on this organ.

Theoretically, with mature third lung technology, even in toxic air, there will be an accompanying sphincter to close the trachea and prevent normal breathing to protect the lungs. The third lung can absorb oxygen from hypoxic or toxic air.

If the existing technology cannot achieve this, then the third lung and the reconstructed blood trachea can only increase the recipient's breathing and oxygen absorption efficiency, and the direct external manifestation is the super endurance that far exceeds that of ordinary organisms.

So here comes the question, these external manifestations can all be explained by reconstructive surgery.

But this Caverns rat not only stammered some common language, but also showed considerable wisdom.

What the hell is this?

Li Wei also briefly read the article on reconstructive surgery. There are a total of nineteen reconstructive surgeries in it, which usually take about three to ten years to complete, but none of the surgeries in it can improve IQ.

Seeing that Li Wei, his 'kind', remained silent, the Caverns' expression changed slightly:

"You have a meat rat thing? Die! die!"

Levi was a little stunned at first when he heard the completely opposite reaction of the Caverns rat, but when he saw the other party's disdainful or even indifferent gaze, he finally understood something.

It turns out that these Caverns rats that had undergone surgery seemed to have accepted Zeelandia's values.

That is the invisible division of the Cavans into three classes.

The best ones are those like him who have undergone surgery and are born with certain wisdom.

In the middle are the 'crazy' delivery rats and the 'are you starving' delivery rats that have been screened out of the food queue? Although they are not very intelligent, their right to survive is also officially protected by Zelandia.

The last ones are those ordinary Caverns rats that have not failed in obedience training. Caverns rats that still succumb to their instincts can only have value as food and materials.

Or if you are lucky enough to be selected to participate in the transformation surgery, those who survive can be promoted to citizens of Zeelandia in one fell swoop, or even join Zeelandia's security brigade to fight for Zeelandia!

Perhaps in the eyes of Brother Cavins, the lowest kind can only ascend to the Kingdom of God and wash away their sins through atonement through flesh and blood.

Calvin's brainwashing skills

It can be seen

After understanding this, Levi couldn't help but show curiosity and inquiry, and responded with interest:

"No meat rats! I'send crazy rats!"

Hearing these words, the Cavans mouse brother changed his attitude again, especially he was surprised that Levi, an ordinary rat man who had obviously never experienced a 'holy call', could speak Common Language.

The two started talking in an incomprehensible language.

After learning that Levi had completed the work at hand, the Cavans mouse brother actually invited Levi to go back to Zelandia to eat grilled fish after get off work later, and he could also take him with him.

And it is highly recommended that Levi also buy an alchemical bicycle that has recently become popular in Zeelandia and even Gelthorne.

At this time, Levi finally noticed the other party's vehicle. His eyes lit up and he accepted the invitation and sat astride the back seat of the vehicle.

This Alchemy Bicycle is completely different from Blue Star's.

Perhaps considering the complex terrain of Zeelandia's underground mines, its wheels are not round.

To be precise, this so-called ‘bicycle’ has no wheels at all!

Instead, there are four arthropod-like metal legs at the front and rear.

I don’t know what principle it uses. Although it uses human power to pedal, I don’t know what the structure is inside. Levi sensed the gathering of magic power in the air, and then the alchemy bicycle seemed to be activated, with eight jointed limbs.

The metal legs strode forward.

Even in complex terrain like the mine tunnel, it ran very fast, almost catching up with the speed of a steam locomotive.

Otherwise, he, the Cavans Rat Man, is an impostor, and he will probably go directly to the Kingdom of Heaven.

Brother Cavins was left like this, and after Levi delivered the last two orders of food in his basket to the miners who had made an appointment for takeout, he happily drove Levi to the city of Zelandia.

The miners did not open the takeout on the spot, but Levi guessed that it was probably rat meat.

Because although the meat of fathead fish is more delicious and nutritious, it does not have the fat layer of rat meat to resist hunger.

In addition, in terms of supply and demand, because fish meat is produced less than rat meat, its price is relatively expensive.

Except for the occasional improvement of food, most of them are used for export to earn foreign exchange.

Although Levi had some inexplicable feelings about this, he had no intention of removing Caverns rat meat from the main food supply list for the time being.

First of all, he is a calm and rational person.

In the Underdark, when food is so scarce, if you make such an unwise decision, you will die! Especially now that the number of people in Zeelandia is increasing day by day!

Later, he was also the person behind Zeelandia.

Even if he is not responsible for the interests of Hog Mining, he still needs to be responsible for the stability of Zeelandia.

As for what I have seen along the way, in terms of mineral development, in the past eight years, apart from the addition of some more transfer stations and the optimization of steam transporters, it seems that not much has changed.

According to Levi's estimation, there is still a problem in the sales market, and the demand cannot be increased, which naturally cannot stimulate Ige and others to focus most of their energy on increasing production capacity.

This will surely be confirmed by meeting the management of Hoge Mining later.

As the alchemy bicycle clicked into the city of Zelandia, the vision suddenly opened up.

Perhaps it was because the miners were getting off work, the alchemy bicycles that Brother Rat rode almost converged into a galaxy of shapes on the somewhat crowded avenue, which made Levi feel like he was back to the days of Blue Star in the 1990s.

a feeling.

However, the 'clicking' sound of so many alchemy bicycles gathered together was too dense and loud, and it forcibly pulled Li Wei back from his memories.

The noise is too much

If it doesn't work, you have to escalate it to Ige, which is really detrimental to the appearance of the city.

Just as Levi told Iger and the others eight years ago, the total population of Zelandia and the upper satellite cities will continue to grow rapidly in the next ten years.

Therefore, Zeelandia has now opened up at least five times the space area to the surrounding area, but it still seems crowded.

In the distance, the area centered on the Hogg Mining Office Building is lined with small high-rise buildings. It has become the most prosperous area in the city center. It is estimated that housing prices have soared.

And just as Li Wei was looking around, a bell suddenly sounded from the north.

Li Wei looked in that direction and was astonished to see a group of children of all races, like cute pets out of their cages, waving copper coins in their hands like rich people, and plunged into various stalls with oil smoke floating on the street.

go.

And at the top of the building complex, there is a very conspicuous door plaque:
Chapter completed!
