Fifth, copper smelting technology

In fact, this technology is closely related to mining technology.

The source of the copper ore of the Divine Envoy King's legion is all from [Malachite City], which is close to the southern mountains, and there is a large amount of malachite scattered on the surface.

The main component of malachite is basic copper carbonate, the chemical formula is Cu2(OH)2CO3, which is produced in the oxide zone of copper sulfide deposits, and often coexists with other copper-bearing minerals, such as azurite, chalcoite, hematrite, natural copper, etc.

The raw materials for the Divine King's Legion to smelt copper are mainly malachite, which is easy to distinguish, and a few other copper ores. Malachite is brilliantly colored and has been a semi-precious stone until modern times.

The only copper-smelting blast furnace of the Divine Envoy King's Legion is located in [Dongyang City], not far from the copper mining area.

The blast furnace is located at a depth of one meter underground, with an interior height of about half a meter, and the temperature of the furnace can be greatly increased by using the thermal insulation properties of the soil. At the bottom of the blast furnace there is a ceramic discharge port, which can introduce the molten copper into the mold, and then the semi-finished product is cooled before grinding into the finished product.

There is a smoke outlet on the top of the blast furnace, and because the exhaust fumes are toxic, the ants dare not approach this land that is scorched by a single fire. The surrounding vegetation is also sparse, creating a small desert.

Interestingly, often after the copper smelting is over and the surface is cooled, the ants can pick up a lot of smoked insects here and get some food for free.

Although it is relatively simple for ants to cast large pieces of bronze, with the production capacity of this only blast furnace, stacking, ignition, smelting, discharging, extinguishing, cooling, and cleaning, a cycle is less than half a month, and its output can be imagined. Therefore, at present, the main use of copper is to produce copper jaw knives, a small number of copper tools, ballista parts and other small devices for the warriors of the Divine Envoy King's legion.

The protagonist has plans to expand another blast furnace, or to repair and rebuild the previous blast furnace that had to be abandoned because of a failed copper smelting experiment that blocked the outlet.

The protagonist already anticipates that next year's war with The Destroyer will be bigger and longer, and more copper will be needed to expand the army to 100 legions.

The protagonist also experimented with ironmaking in the copper smelting blast furnace, and the principle of the two is the same, both rely on the temperature of the blast furnace to achieve redox reactions.

Although no large-scale iron ore has been found in the territory, there are still scattered rusty hematite sands, and the ants have collected enough to conduct experiments.

It's a pity that the temperature of the copper smelting blast furnace has never been able to go up, and the melting point of iron cannot be reached.

In the next step, the protagonist plans to research ways to make better charcoal, using charcoal as fuel to increase the temperature of the furnace.

In ancient China, a large amount of high-quality iron and even steel was smelted using the charcoal soil method, which was of better quality than the iron smelted later with coal (coal contains sulfur, which will embrittle the finished iron).

Now that there is a precedent for success, the protagonist believes that he can do it himself.

Sixth, animal husbandry and domestication technology

Big-headed ants have been grazing aphids before, and many species of ants have this technology. However, this is not an invention of ants, but just that ants and aphids have taken what they need in the long process of evolution.

The real domestication technique is brought by the protagonist and the remnants of the big-headed ant.

The main character teaches the ants the breeding of mealworms and the domestication of flies and bees.

Mealworm breeding can not be regarded as domestication in the full sense, after all, mealworms themselves are very adapted to this kind of life of being raised, and there are no physiological changes due to changes in the living environment, which does not meet the definition of domestication.

It doesn't matter to the ants, anyway, the meat obtained by breeding mealworms is already abundant enough.

The domestication of flies is a very fulfilling thing for the protagonist, and its domestication method is completely different from the domestication of dogs, horses, cows, sheep, pigs, etc. The protagonist succeeded by mistake and inexplicably without precedent, which is why the current Flying Knight Legion was born.

Although the fly is only semi-domesticated in the strict sense, similar to a wild boar that has just been domesticated by humans, it is already a remarkable flyover.

The domestication of bees can be seen as a follow-up to the domestication of flies, and the two are essentially the same. Moreover, bees are inherently social insects, and they are also closer to ants and easier to domesticate.

Beetle domestication is quite different from the domestication of the first two, beetles are not social insects, nor are they as intelligent and neurologically developed as flies, and adults cannot domesticate.

This technique of domesticating beetles was taught by the remnants of the big-headed ants, and the trick is to domesticate the beetle while it is still a larva and pupa, and then intensify its domestication when the adult has just broken the pupae.

At present, the number of beetles in the Divine Envoy King's army is steadily rising, and the protagonist also intends to make the beetle army a "torrent of steel"!

Seventh, agricultural planting technology

This technique is lackluster, in fact, some grass seeds that the ants regard as food are sown on the flat land, and the harvest is basically dependent on the sky, and the ants only do some basic care, neither seed selection, nor irrigation and fertilization.

But even so, the grass seed production from the densely planted weeds is enough to meet the food needs of the ants.

8. Fermentation technology

This technique was also learned from the remnants of the big-headed ants, and it is mainly used for food processing, which enriches the food variety of ants and can also allow some foods to obtain a longer shelf life.

Nine, the technology of city building

Ants have their own nest-building techniques, and in the human world, some ant nests are known for their large scale and intricately structured.

The nesting skills of ants in this world are even better, including underground nests like [Dongyang City], semi-underground nests with huge mountain packs like [Qingqiu City], and tree cities like [Linshui City].

Whether it's on the ground, in trees, in swamps, or in the desert, ants have a suitable way to nest.

The main character, on the other hand, has improved the way ants build their nests, so that they can be called "castle building".

The "Ant City" he designed has a tall ant mound like a termite mound, and there are walls on the periphery, which can play a dual role in military defense and flood control. The ditches outside the city walls also served the dual role of military defense and flood relief.

Such a city is more important for the improvement of defense capabilities, whether it is city walls, moats, protective nets, or intricate underground passages, they are all designed to enhance the defense of the defenders.

Paired with elite defenders and indestructible ballistas, even destroyers or parasitic beasts will have to break their halberds.

The above nine categories are the current scientific and technological level of the Divine Envoy King Legion, which has basically reached the level of Neolithic primitive people on the whole, and has slightly exceeded individual scientific and technological points.
