Since the discovery of the Nilkoco people in 648, Bailiyan has successively sent expeditions and agricultural experts to Lingjing Island to investigate and contact, and brought advanced agricultural technology to the local Nirkoco people.

Due to the lack of livestock in the local area, in the past three years, Bailiyan organized a fleet to transport a total of more than 50,000 fragrant pigs, 200,000 chickens, ducks and geese, more than 10,000 dwarf horses, more than 900,000 pieces of iron tools, 1,000 stone of grain seeds, and tens of thousands of other daily necessities.

The Nilkoco traded local specialties and precious stones for supplies from the Xian country, a trade that was already unfair to the Nirkowo because of the disparity in productivity.

In view of this, Bailiyan adopted fair trade measures, and the goods of the Xianguo side were sold at a loss, in exchange for the relatively high price of special products of the Nilkocles, so as to balance the trade between the two sides, so as to make a good alliance with the Nilkocos.

And as the information provided by the wild land, Bailiyan found early species talents in the Nilkoc people, one is eagle eye, the second is language talent, the third is that their IQ may be slightly higher than that of humans, and the fourth is that they live longer than humans.

The eyeballs of the Nilkocos are twice the size of humans, bulging outward, and have five to six times the visual acuity of humans.

Normal human vision can clearly recognize the facial contours of a humanoid target from about 400 meters away, while Nirkoc people can achieve the same recognition effect from 3 kilometers away.

This means that the same optical electronic devices, they can see substances that humans can't see, integrated circuits that humans need to use a magnifying glass to see, they don't need at all, and a pair of delicate eyes in surgery is extremely important, they can do more delicate surgery, engage in precision machining.

The second is their language talent, their hearing is developed, they can imitate animals to do simple communication, the expedition sent by Bailiyan, the Nierkoko people only took half a year to learn 80% of the daily pragmatics of human beings, while the scholars of Xianguo are still learning their basic vocabulary and sentences.

In addition, the people of Nirkoko had a high IQ and a level of productivity that reached the limits of what the Bronze Civilization could achieve, and it was found that their society was already equipped with smelting and primary machinery, as well as systematic basic education.

What shocked Bailiyan the most was that the average life expectancy of the people of Nilkocco had reached 70 years, and the oldest elderly could live for more than 120 years, and if material abundance and medical conditions improved, their life expectancy could be doubled.

At present, the average life expectancy of human beings is less than forty or fifty, and even more than thirty years old during the war, such a huge difference in life expectancy means that if they develop on the same level as human beings, the number of intellectuals of the Nilkocco people will be greater, and science and technology will one day lead mankind.

Although the heavens have given the people of Nilkoko a remarkable talent for species, it also makes them troubled by their own talents.

Nilkocko is short at less than three feet, has a gestation cycle of about 10 months, is longer than humans, and is surrounded by an environment that dictates that early threats come from carnivores and large animals.

Due to the lack of horses, cattle, and pigs on the island, and the lack of iron ore resources, the development cycle of its agricultural civilization will be very long

As a result, the Nirkoc people were vulnerable in the early Stone Age, the Agrarian Age, and even in the Industrial Age, where physical labor would severely reduce their efficiency, but would also stimulate them to focus more on improving automation and mechanical efficiency.

All in all, most civilizations have their own limitations and talents, and Nilkocco is the prime example.

The people of Nierkoko are simple and honest, hospitable, good at learning, industrious and simple, and the society is almost on the best side of human nature.

3,000 international students will be arranged to go to Xuanyun to study language courses, and then study basic mathematics and natural sciences for two years, and after two years, they will be arranged to study herbal medicine, agriculture, fishery and animal husbandry, mathematics, carpentry, pottery, textiles, basic mechanical design, metallurgy, focusing on training disciplines that can immediately improve the living environment of society, with a duration ranging from three to five years, and those who are excellent are allowed to continue their studies on an exceptional basis.

Due to the short size of the Nilkoc people and the developed hearing and visual systems, the efficiency of teaching one class of humans can teach six classes of Nirkok people, which is also the main reason why Bailiyan agreed to study abroad for 3,000 people.

From 650 to 651, Bailiyan did three unprecedented things, one was to cut the three counties of the eldest grandson, and the other was to lay the railroad tracks and open the train, which was no less than the great cause of five thunders to open the world, and the vassal states were still thinking hard about how to break through the annual output of one million catties of iron, when the Xianguo had begun to "practice" tens of millions of catties of good steel.

The third thing is that the Nirkocco people sent an embassy to the Xian country, in fact, the Nirkocco themselves are not enough to cause much of a sensation, in the eyes of the vast majority of human beings, the Nirkocco people cannot be regarded as people at all, they should be some kind of livestock like other animals, and even better they are foreign barbarians, and they will not be treated as equals at all.

What really stimulated the princes and even the Liang State was the "tribute" of the Nilkocco people to the Xian State and the establishment of an embassy, which was no less political in nature than a political event.

Following Jin Xuedi's submission of the letter of state to Xianguo, the three tribes of Western tapirs have successively bypassed Liang and Xianguo to trade, and the Nierkoko people bypassed Liang to set up an embassy in Xianguo, which stimulated Liang a lot, and public opinion denounced Xianguo as a "barbarian friend" for a while, which means that Xianguo will only have different contacts with others.

In April of the same year, the two-way railway from Yongxing to Chenling was stopped, the one-way railway from Changqu Iron Mine to Yongxing was repaired, and the section west of the Yongxing River Railway Bridge continued to extend, and as of July of that year, a total of more than 600 miles of railways were laid.

In view of the lack of technical work and experience, Bailiyan did not plan to expand the railway too quickly in the first two years, but still focused on accumulating experience and cultivating railway infrastructure talents.

In May, after preliminary technical preparations and test demonstrations, the Yongxing Processing Plant began to upgrade the technology of the 645 platinum-based copper-nickel-iron-based alloy breech gun of the whole army.

The modified breech loading gun will use a disjointed threaded gun latch lock, a double sealing of the cartridge barrel and sealing ring, and a hydraulic re-entry mechanism, so as to realize the three key technologies of loading locking, gas sealing and artillery recoil in one fell swoop.

Due to the thick wall of the 645 gun body and the advanced quality of the steel, there is room for upgrading and improvement at the beginning of the design, while processing the inner hole, a rifled tube after forging is inserted, and the rifled tube is pressed into the 645 barrel formed by secondary processing by using a hydraulic press, so as to realize the self-tightening and spiral rifling of the tube body, so as to enhance the rifling pressure and artillery accuracy of the gun.

At the same time, after the rifling is worn, the inner tube only needs to be pressed out and replaced, and the gun body can be repaired and reused, saving industrial time.

The technology of artillery upgrading and improvement has been demonstrated and completed two years ago, whether it is the latch locking of the broken threaded gun, the double sealing of the cartridge and the sealing ring, and the hydraulic re-entry mechanism, the design has been completed in theory, and these three technologies are all based on the cognition of Bailiyan's previous life, but there is one thing that cannot be avoided, that is, industrial capacity.

Without the processing capacity, any foreseen technical path cannot be realized.

At the end of May, Lincheng and Yongxing were successively electrified, and lighting and telephones were put into use, in view of the shortage of electricians and the danger of electricity, electricity was limited to Lincheng, Yongxing and Xuanyun.

However, the overhead lines to various localities continued to be laid as originally planned, and within three years the counties would be connected to telephones and wired telegraphs.

In June, the first phase of the Yongxing vehicle factory project was completed and put into operation, using the assembly line, equipped with as much power equipment as possible to increase the output, the first batch of walk-behind tractors, harvesters, pickups and medium trucks 52 vehicles have been off the assembly line, to accept a period of three months of high-intensity testing and improvement, October formal production, the driver's school was established at the same time.

Thanks to the data modeling and technical optimization in the early stage of the storm, the design index has reached almost 95% of the theoretical index, and at the same time meets the current industrial technology production capacity.

Due to a large number of preliminary calculations and simulations, the products with excellent design data are almost free of technical defects, and at the same time can meet the current industrial processing capacity.

The only problem is the operator's personal error caused by non-standard production regulations, as well as the failure and man-machine efficacy caused by the later assembly and decoration, and there is almost no problem with the technical principle.

In view of the constraints of industrial conditions, vehicle production avoids aesthetics as much as possible, and only considers practicality, so the shape of the general-purpose vehicle is passable at best, and there are only two models: pickup and medium-duty trucks.

Bailiyan's original plan was to produce pickup trucks and light trucks, but the multi-cylinder engine was only developed to four cylinders, and many design indicators were not satisfactory.

The four-cylinder internal combustion engine developed on the industrial basis two years ago is only enough to drive pickup trucks and light trucks with a load of less than 40 stone (about 25 tons), and the indicators of medium trucks with a load of 1 or 200 stone cannot be reached.

The in-line four-cylinder engine that has been developed is just to meet the needs of pickup trucks and light trucks, while the single-cylinder, two-cylinder and three-cylinder engines can meet the needs of walk-behind tractors, harvesters and generators.

After the new optimization, Wildland came up with a new internal combustion engine structure, which does not need to change the internal combustion engine material, nor does it need to improve the fuel composition and air compression ratio, but only needs to increase the bore and bore thickness to strengthen the strength of the body, add two repeated combustion chamber stamping type, optimize the existing body structure, and use the principle of incomplete combustion and secondary compression of fuel gas to improve the efficiency of the internal combustion engine.

Under the premise of increasing the weight of the internal combustion engine by 20 percent, the output power is greatly increased, the load is 95 stones, the three-axle six-wheel structure is used, the pneumatic drum brake brake brakes, and the maximum highway speed is 150 miles per hour, which can barely be regarded as an ordinary medium truck.

However, such a good design, there must be drawbacks, need to drink a lot of water cooling, water consumption is more than three times that of ordinary four-cylinder engine, the advantage is not to greatly change the mold design, to meet the current industrial production technology under the premise of maximizing fuel efficiency, and fuel consumption is not much more than the original.

Of course, if the traditional structure of the six-cylinder engine is directly used, the same power output can also be achieved, but Yongxing City has not yet begun to develop the six-cylinder engine, and the technical reserve is insufficient.

Moreover, the six-cylinder engine is not just on the four-cylinder, adding two cylinders is as simple as a re-enactment, almost all the data and design are redone.

At the same time, limited to the limitation of industrial processing capacity, there is neither CNC machine, nor copy machine tool, must first remove the allowance by the traditional cutting machine tool, and then manually processed by the fitter, it takes more than a month to produce and manufacture a set of single-cylinder machine molds, nearly 400 hours, and a set of four-cylinder machine molds takes two and a half months.

It does not include the time-consuming mold modification that needs to be spent on trial production in the later stage, and the six-cylinder engine will take longer, and it needs to be redesigned and demonstrated, and the relevant technical indicators and standards need to be formulated.

The four-cylinder engine has been designed and finalized, there are ready-made molds, a full set of technical indicators, and the time cost of modification on this basis is much less.
