Back then, when Levi handed over the 20 genetic protogens and 19 surgeries of the Imperial Ultramarines to Iggy, he had repeatedly instructed him.

It must not be put into clinical use until the technology is mature.

He didn't want his soldiers to die on the battlefield without meaning on the bench.

But the Cavins were not among the Cavens at the bottom of the food chain at the time.

Because of their lack of intelligence and instinctive behavior, the Cavins rat-people were not classified as sapient creatures by Levi.

Even though they gradually developed a high level of obedience and a certain amount of intelligence under Calvin's training, and began to get involved in the delivery and food delivery industry, it can still only be regarded as the result of training.

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

Therefore, the Cavins rats, who failed to embody this value, became the guinea pigs in the Iggy Biochemical Laboratory as the materials for the transformation of the experiment, after being the suppliers of food and fur

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

According to Levi's eyesight, it should have undergone at least five surgeries on the second heart, bone-strengthening organs, muscle-strengthening organs, hematopoietic organs, and the third lung.

First of all, without the growth hormone provided by muscle-strengthening organs, the Cavens would not have been able to grow to this size that is almost several times the size of their peers.

And such a brother and noble muscle, if there is no bone strengthening organ to enhance bone strength, then it is also a pile of rotten meat that can't 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 the absorption of ceramic compounds added to the modifier's ration by bone tissue.

Two years after implantation, this will cause significant reinforcement of the long bones and extreme ossification of the thoracic cavity.

Among them, the ribs will grow into bony plates, which will overlap each other and become one, and increase the bone size of the receptor in general.

I don't know if Iggy can invent a similar hormone, otherwise the modified Ultramarines will have some discount in survivability.

Well, with such a strong body, it is natural that a strong oxygen supply system is also needed to supply energy.

Therefore, the second heart, the third lung, and the reconstituted hematopoietic organs become necessary.

Second, the heart not only speeds up the blood supply, but also maintains intact physiology when the recipient's original heart is damaged.

The third lung, on the other hand, is essentially a gray tubular organ through which blood flows from the blood vessels grafted into the recipient pulmonary system, and air is drawn in from the dilator muscles on this organ.

Theoretically, the well-established third lung technique, even in toxic air, has a companion sphincter that closes the trachea and prevents normal breathing to protect the lungs, and the third lung can absorb oxygen from the hypoxic or toxic air.

If the existing technology cannot do this, then the third lung and the reconstituted blood trachea can only increase the respiratory oxygen absorption efficiency of the receptors, and the direct external manifestation is the super endurance far beyond that of ordinary organisms.

Then the problem is, these external manifestations can be explained by reconstructive surgery.

But this Cavins rat not only stammers some colloquial terms, but also shows great wisdom

What the hell is this?

Li Wei also had a cursory look at the literature on reconstructive surgery, which contained a total of 19 reconstructive surgeries, which generally took about three to ten years to complete one after another, but none of them could improve IQ

Seeing that Levi was silent, the Cavins rat man's face changed slightly:

"Meat rat thing?!!"

Levi's reaction to seeing this Cavins rat was diametrically opposed at first, but when he saw the other party's disdainful or even indifferent gaze, he finally understood something.

It turns out that these operated Calvins rats seem to have embraced Zelandia's values as well.

That's the invisible division of the Cavins rat people.

The best ones are the brother nobles like him who have undergone surgery and have given birth to a certain amount of wisdom.

In the middle, there are the crazy courier rats and the hungry food delivery rats who have been screened out of the food ranks, although they are not very intelligent, but their right to live is also officially protected by Zeellandia.

Finally, there are ordinary Cavins rats who have failed in obedience training, and Cavins rats who still succumb to instinct can only have value as food and materials.

Or if you are lucky enough to be called up to participate in the transformation operation, and if you survive, you can become a citizen of Zeellandia in one fell swoop, and even join Zeellandia's security brigade to fight for Zeellandia!

Perhaps in the eyes of the Cavins Rat Brothers, they all think that the lowest kind can only be atonement for their sins through flesh and blood to ascend to the kingdom of God and wash away their sins.

Calvin's brainwashing kung fu

It can be seen

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

"Meat rat!

Hearing this, the Cavins Rat Brother changed his attitude again, especially when he was amazed that Levi, an ordinary rat-man who had obviously not experienced the Holy Calling, could speak the lingua franca.

The two of them just talked in a rat-like language.

After learning that Levi had finished the work at hand, the Cavins Rat Brother actually invited Levi to go back to Zeellandia for grilled fish after work later, and he could take him with him.

And highly recommend Levi also to buy an alchemy bike that has recently taken Zeelandia and even Gerthorne by storm.

At this time, Levi finally noticed the other party's vehicle, and couldn't help but light up, and was invited to straddle the back seat of the vehicle directly.

This alchemy bike is very different from the Blue Star's.

Perhaps considering the complex terrain of Zeelandia's underground mines, it is not a round wheel.

To be exact, this so-called bicycle has no wheels at all!

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

I don't know what principle it uses, although it is also used to pedal, but I don't know what the structure is inside, Levi sensed the convergence of magic in the air, and then the alchemy bicycle seemed to be activated, and the eight arthropod metal legs strode forward.

Even in the complex terrain of the mine road, it is fast enough to catch up with the speed of a steam locomotive.

Otherwise, he's an impostor, the Cavins rat man, and I'm afraid that he will go directly to heaven when he hits him.

After Brother Cavins stayed like this, Levi delivered the last two orders of food in his basket to the miners who had booked takeout, and then happily drove Levi to Zeellandia City.

The miners did not open the takeaway on the spot, but Levi guessed that it was most likely rat meat.

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

In addition, in terms of supply and demand, fish meat is relatively expensive because it produces less meat than rat meat.

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

Although Levi also had some inexplicable feelings about this, he did not have the idea of removing Cavins rat meat from the main food supply list for the time being.

For one, he is a calm and sane person.

In a dark region, with food so scarce, it would be fatal to make such a mindless choice!

He is also at the helm of Zeellandia.

Even if he is not responsible for the interests of Hoag Mining, he is responsible for the stability of Zeellandia.

As for what I saw along the way, in terms of mineral development, in the past eight years, except for the addition of some transfer stations and the optimization of steam conveyors, it seems that there has not been much change.

According to Levi's estimate, there is still a problem in sales, and the demand cannot be raised, so naturally it cannot stimulate Iger to focus most of their efforts on increasing production capacity.

This will probably be confirmed by a meeting with the management of Hoag Mining later.

As the alchemy bike clicked into Zeellandia City, the eyes suddenly opened up.

Xu was because he was at the time when the miners were off work, and the alchemy bicycles similar to those ridden by Brother Rat almost converged into a galaxy on the somewhat crowded avenue, making Levi even feel like he was back in the nineties of Blue Star.

However, the clicking sound of so many alchemy bikes gathering together was too dense and loud, and it forced Levi back from his memory.

It's too noisy

No, you have to react with Ig to escalate, it's really detrimental to the city.

As Levi told them eight years ago, the total population of Zeelandia and the upper satellite will continue to grow rapidly over the next decade.

As a result, Zeellandia has now expanded its area to the periphery at least five times as much space as before, and it is still crowded.

In the distance, an area centered on the Hoag Mining office building is like a forest of small high-rises, and it seems to have become the most prosperous area in the city center, and it is estimated that housing prices have soared.

And just as Li Weidong was looking west, a bell suddenly rang from the north.

Li Wei looked in that direction, and was stunned to see a group of children of all ethnic groups waving the copper coins in their hands like big money, like big money, and rushed into all kinds of stalls with oil smoke floating on the street.

And at the top of the complex, there is a very conspicuous door plaque horizontally:
