The breath of spring descends on the earth.

This year's spring ploughing in the Lei Niu Department is different from previous years, and the difference is very big.

The infrastructure of Xinjing has been completed, and it is bounded by a mountain pass to the southwest, and the entire northern hills and adjacent areas are all used for potato cultivation.

Cutting, breeding, cultivation...... The basic procedure was no different from that of the civilized era, and the amount of seeds brought from the south of the continent through Elizabeth was large enough to fill all the arable land areas of the walled cities under Tianhao's rule.

Seawater rice is extremely adaptable, just like people who live in poverty all year round and will not refuse a rich feast of fish and meat, and rice varieties that have gone through a long period of time also prefer fertile land, they grow vigorously in areas with abundant water flow, and their yields far exceed that of wheat.

According to Tianhao's order, the people reduced the area of wheat cultivation and replaced it with corn brought from the south. They were surprised to find that the biggest difference between this year and previous years was that the area used for cultivated land was wider. Dry lands with little water, hills, gentle slopes, and even some mountainous areas with little difference in height are included in the cultivated areas. Among them, the most sown crops are corn and potatoes.

The effect of pulses on soil nitrogen fertilizer is very obvious. This is knowledge that has been left over from the age of civilization to the present day. In addition to the normal fallow rotation of soybeans, Tianhao has increased the amount of rapeseed seeds, and if the wind and rain are good, this year's vegetable oil production will reach unprecedented values.

The barbarians of Rock City fell in love with tomatoes. The red and bright fruit looks very warm, and the sweet and sour flavor is even more lovely. It does not have high soil requirements and can be planted in front of and behind the house. Even Tianhao himself did not expect that in a short period of time, tomatoes swept the entire Lei Niu Department at a terrible speed, and to some extent even replaced cucumbers (the traditional summer vegetable of the northern barbarians) and became the popular crop unanimously praised by everyone and with the highest support rate.

Tianhao became more and more sure that the thorn melon was the mutated pumpkin. Its terrifying appearance has not affected its growth characteristics, as well as its strong ability to adapt to the environment. The hard shell is very troublesome to deal with, and the golden flesh is very delicious, especially when used as a cultivation seed, and people deliberately leave it on the melon vine to grow up and age, and the flesh is soft after steaming, and when kneaded with flour or rice flour, it can be made into a snack that children like.

Mushroom houses are rapidly spreading throughout the Thunder Cattle Department, and a variety of mushrooms, including black fungus, have been appearing on people's tables since last winter. Boletus, mutated artificial mushrooms, the color is not very white, the overall gray variant of the mushroom, the appearance is very different from the civilization era, into a tower-shaped pine mushroom...... As long as the temperature and moisture are ensured, leaving a small amount of hyphae on the humus, they will soon be able to multiply and grow, appearing in the form of delightful clusters of flowers.

The number of fanged pigs has doubled compared to last year. Tianhao was not satisfied with this number, but he knew that farmers everywhere had done their best. There is no way, the source of feed is very narrow, and pigs can only be raised on the premise that the barbarians must be fed, and it is already good to have this number. Overall, the key lies in this year. If corn and potato yields increase dramatically, plus soybeans and rapeseed for oil extraction, soybean meal and oilmeal could be added to the feed list for fang-toothed pigs, as well as a small amount of corn.

Only when they are full can they grow strong, and only then can boars and sows have the heart to fall in love, and then deepen to the problem of breeding offspring...... In this respect, they are no different from humans.

The mountain road leading to the northern lake area has been opened, and 20,000 Niu people, including the dry vine village, have moved there. Mountains are being blown up, trees are being cut down for houses, and a whole new city is emerging.

According to the previous regulations, Tianhao named it the Third Production and Construction Corps.

The scale of breeding of giant horned deer has not expanded, on the one hand, because of pasture, and on the other hand, Tianhao ordered the focus of breeding to shift to cattle and sheep.

Although the deer are docile, they are far less manageable than cattle and sheep. In particular, cattle, the mutated breeds in the north of the continent are tall and large, continuing the robust but slow-moving characteristics of their counterparts in the era of civilization. Bison don't run as fast as bighorn deer, making it easy to catch and domesticate. What's more, the barbarians live and breed on this land, and large-scale domesticated and mature herds have long appeared.

The special breeding of dairy cows has been started since the year before, mainly to keep the lactation state for a long time, to limit their activities in a narrow area, reduce the energy consumption in the body, and at the same time supplement the green fodder feeding, to get a large amount of milk.

Cheese has become one of the most important commodities in Tianhao's hands. There are two types of cheese according to its quality, and the difference is the amount of adulterated flour. For the common people, it is the ordinary type, that is, the coarsest and worst tasting. Despite this, there are not many people who are eligible for this "special ration", mainly pregnant women, children, military personnel.

The taste of the high-quality special products was very good, and the savages who worked on the farms quickly developed a fragrant cheese. The price of this goods is extremely expensive, except for a small number left for internal use within the tribe, and most of it is sold to the lion and tiger tribes.

The area under cultivation of apples and grapes has increased fourfold compared to the past, and about half of the trees are able to bear fruit that year, and the grapes are in better condition, with 80 percent of the areas planted so far bearing fruit. Tianhao ordered that the general fruits be used for winemaking, and the rest were all made into raisins, which were listed as strategic reserves for the Thunderhorn Division.

The importance of military rations is self-evident, and in addition to satisfying the normal needs of the clan, Tianhao tried to make compressed biscuits. It is a method of drying and pressing raw materials such as beans, flour, and minced meat, mixed with a large amount of oil and various seasonings. In terms of taste, it is not much different from the civilized era, and the real breakthrough in technology is due to the use of sufficient amounts of sugar, and the largest source of this kind of stuff is Jeju Island at present.

Cheonho did not transplant the sugarcane, and the cultivation area was limited to Jeju Island. The sheer size of the area, combined with the constant cultivation of new land, produced enough sugar to meet most of the needs of the barbarian race.

The shipyard is currently producing the highest production ever. Take the "Viper" class of sea vessels, for example, there are as many as thirty-five in total. In addition, there are a large number of small and medium-sized fishing vessels.

The whaling industry is unprecedentedly developed, and almost every time the fleet goes to sea, there is a harvest. Bighorn whales and blacktip whales, in particular, are extremely widespread and incredibly numerous in this area. The northern barbarians lagged far behind the southern whites in navigation, and the early flat-bottomed boats were suitable for inland navigation and could not penetrate deep into the sea. If it weren't for Tianhao getting complete construction technology from the "old mama", this situation would not be able to change until now.

With the newly built Liandu City as the core, people started from a series of processes such as whaling, decomposition, fat boiling, skin kneading, and meat processing, forming a complete industrial chain. Of course, the main body is still based on food, the whale meat that cannot be digested in a short period of time is cut into small pieces, sprinkled with salt to dry, whale skin and whale bone are used for other purposes, in addition to the large pieces of fat that are normally salted as food, more than half of the whale fat is boiled into liquid, cooled and put into a clay vat, sealed and preserved.

Last winter, the first lathe appeared in Rock City.

It was extremely difficult to be born, and it was made by hundreds of craftsmen, and it was carried out little by little on the iron with hammers and steel files, and it took a lot of painstaking work to finally "smash" something that could be called a prototype.

By all accounts, this lathe is primitive and functionally simple, nothing more than ordinary metal cutting. But it is undeniable that its importance lies in reducing the difficulty of replication of subsequent lathes. Tong Biao has calculated that the overall difficulty of making the second lathe is reduced by 70% compared with the first one, regardless of manpower or materials consumed. What's more, the third, fourth, and fifth stations have since ...... The subsequent manufacture of all lathes will become easier and the related technologies will become more sophisticated.

The benefits of large-scale steelmaking are starting to be felt. Tianhao calculated the raw materials he currently had and ordered the construction of the first railway between Thunderhorn City and Rock City at the same time as spring ploughing.

He had drawings for the manufacture of a steam engine, but there was no rubber to seal the machine itself, so it was naturally impossible to make a steam locomotive under such circumstances.

Laying rails on the basis of the existing roadbed and pulling wagons full of goods with human or animal power is an expedient measure that Tianhao has repeatedly considered.

The time and difficulty of transportation between the two places must be simplified in order to speed up the flow of goods. The "cow pulling the train" may seem funny, but it has extremely important significance.

The breeding of the herd has never stopped, Zumu sends some mares every month, and the Tiger people have never found out about the leakage of secrets. Tianhao moved the farm to the north, and before the horses were formed, he would not actively expose them, but would only hide everything.

Every two ships become a team, and Cheonho sends twelve teams to explore the depths of the ocean with Jeju Island as the core.

The map he had received from the "old woman" came in handy, and every sea ship assigned was equipped with a map, and Zhengjiang, who had been promoted to the commander of the fleet, issued a decree that everyone on board, from the captain to the ordinary sailors, must swear a blood oath to the gods———— no matter what kind of danger they encounter at sea, they must destroy the charts at the first opportunity, tear them apart, chew them, swallow them, and ensure that these precious secret documents fall into the hands of the white southerners.

There is no Australia in this world, and the distant continent has long since been shattered by the asteroid impact, floating in the form of a series of small islands in the distance.

The fleet sailed southeast, crossed the temperate zone, entered the perennially hot area, and found a large one marked on the chart at a position of more than 1,300 nautical miles from Jeju Island.

If you compare the maps of the civilization era, you will find that it originally belonged to Indonesia, and the earth's crust was compressed to form mountains, and the uplifted part was above sea level, forming a massif an area equivalent to a quarter of the Indian peninsula.

The Slaughter was one of the lucky ones to discover this place, but unfortunately no rubber trees were found here. The island is overgrown with bushes and a large number of coconuts and bananas. The "Killing" and half of the sailors who accompanied the ship, including all kinds of necessities, turned around and headed for the way they came.

Cheonho has already named this island ———— Jinju Island.

The 600 sailors who arrived in advance were to build villages and fortifications here to lay the groundwork for the migration that would come in a few months. It's a truly tropical region, and you can't wear any animal skin clothing, except for thin cotton shorts and sweat jackets, so you won't feel cold even when you sleep at night.

The process of "finding" land and immigrating must be done with great care. White Southerners began ocean exploration decades ago. They had more ships, and their desire to discover and occupy them was extremely strong, and many of them had overseas territories, including the nobles of the major kingdoms. Because of factors such as ship performance, wind and waves, and climate, the exploration area of the southern whites is not too large, and it is still mainly near the southern continent, and does not go further into the farther places.

Tianhao does not plan to emigrate overseas on a large scale at the moment.

There is still a large blank area in the northern part of the mainland, and hundreds of thousands of people have smashed into it, which can only occupy a small area at best. The basis of development and exploration lies in food, and with the strong physique and fertility of the barbarians, large-scale reproduction is not a problem at all. As for those overseas islands and land, it can only be said that they were occupied before they were discovered by the whites. In the case of Jinju Island, for example, the number of immigrants will not exceed 3,000, and the number of immigrants will double in a few years.

The training of dragoons has begun. After several years of capture and domestication, people have explored a set of mature domestication methods. Originally, the barbarians hunted all kinds of beasts and fed them to the velociraptors with fresh minced meat. It was later discovered that they were not interested in these carnivorous foods, and specifically preferred a species of giant rat endemic to the northern mountains.

Adult giant rats are more than one meter long and can even reach six or seven meters. Their appearance is not much different from that of civilization, and radiation causes them to be larger than normal, which in turn is fixed deep in the genes, and is inherited from generation to generation. The diet of giant rats is very extensive, plant fruits, roots, nectar, insects, small animals, and many more...... Even large beasts must turn around and flee when they encounter hordes of giant rats, otherwise they will be swarmed and will have to wait for death and then share the food.

Velociraptor is the natural enemy of giant rats, which is a bit of a life-and-death relationship between owls and mice in civilized times. The sheer size of the mountain ranges limits the spread and communication of species, especially before Tianhao "wakes up" from the pod, and few barbarians have taken the initiative to set foot in this area, let alone commit the horrific suicide of "catching the velociraptor dragon".

Maybe it's because of the radiation, or maybe it's because of the special food structure that fixes the life circle of the giant rat. They are bounded by the fourth mountain range in the north, and there has never been a record of a trip south.

No one has counted them, but judging by the dense vegetation of the northern mountains, the giant rats should not have formed a catastrophically large colony, otherwise they would have been eaten away by a long time ago, leaving only bare hills.

The basic armament of the dragoons consisted of muskets, halberds, and sabers. Powerful physical strength can be complex and heavy armor, and after more than 30 tests before and after, the white musket could not penetrate the armor covering the surface of the velociraptor body.
