The Armory Bureau only took two days to build, and the stats were not bad.

[Armory: A department used to research, develop, improve, and craft weapons; Research Speed +10, Excellence +8, Craftsmanship +10, Work Efficiency +10]

Although the attributes have only increased slightly, the effect is very good, Su Lun has arranged thirty craftsmen here, and now the first weapon studied by the Armory Bureau is the crossbow.

The crossbow obtained by Suren was simple in structure, small in power, short in range, and slow in winding, and had no advantage over the current centaur longbow and elven longbow, and was not much different from the birch bow used by human archers. At this level, there is no advantage at all after equipping a crossbow, so Su Lun plans to research and upgrade it before equipping it.

Of course, even if you want to research and upgrade the crossbow, you need to make the basic crossbow first, the crossbow is a weapon that many countries have equipped, but they prefer the powerful bed crossbow, there is not much research on small single crossbow machines, and the price of making a crossbow machine is not a small amount, so the popularity of small crossbow machines in various countries is not high.

Ordinary crossbow arrows are not a high threat to knights, in this transcendent world, a knight can rush back and forth on the battlefield wearing plates, and ordinary crossbow arrows cannot pierce plate armor at all. Only large bed crossbows can pose some threat to them, but bed crossbows are heavy and difficult to move, as long as they are detected in advance, the hit rate is lower, and they are more suitable for siege or defense purposes.

Because he had mechanical control and had made bed crossbows before, it was not difficult for him to make small crossbow machines. Let those craftsmen give themselves a hand, and Suren will make it according to the blueprints of the crossbow machine.

As long as the bracket of the crossbow machine is made of metal, this part can be poured directly in the future, and the other places use elastic wood, and the bowstring uses some materials such as cow tendons, and the bowstring used on the crossbow machine is more tough than ordinary bows and arrows, so it is made of several cow tendon tanning, and iron wire can also be added when necessary to increase strength.

With the last part completed, Suren finally finished making all the parts of this crossbow machine? Moved some body? Suren picked up the parts and began to assemble, compared to the production? Assemble it much faster? In just ten minutes, a crossbow was made.

In fact, the crossbow machine in the drawings given by the system is an arm tension crossbow? However, the speed of the crossbow is slower, so Su Lun modified it? It became a crossbow. Is it to add a pedal to the front end of the crossbow? When opening the crossbow, stepping on the pedal with one foot and pulling the string with both hands, it is faster and less labor-saving than winding it completely with both arms.

Suren trying to pull the crossbow open? And then put a special bolt on the crossbow machine? The arrows used in the crossbow machine are different from those used in the bow, the crossbow arrows have no feathers and no bow and arrows length, and after the crossbow arrows are fixed, Suren and the other craftsmen go to a weapon testing ground in the back.

Have people place their targets at 50 meters? Eighty meters, one hundred meters and one hundred and twenty meters apart? Suren began to conduct tests. Holding the crossbow machine in one hand and the handle in the other? Then aim the crossbow at a distant target and pull the trigger with your finger.

"Collapse!"

The sound of a bowstring vibrating? A crossbow bolt instantly shoots at a distant target? Right in the bull's-eye. Next, Suren continues to wind up and shoot? Crashing and collapsing, a continuous bowstring sounded, and in a short time, Su Lun shot out more than a dozen crossbow arrows.

Next, we began to look at the lethality of the crossbow arrows, among which the crossbow arrows on the fifty-meter arrow target directly penetrated the arrow target, these arrow targets are made of hardwood, the thickness is enough to be seven centimeters, it is not easy to penetrate, and the crossbow arrows on the eighty-meter arrow target are not very deep.

On a 100-meter target, the depth of the crossbow arrow is very shallow, only about one centimeter, while the crossbow arrow on the 120-meter target can be easily pulled out, and it is basically no longer lethal. Su Lun's tensioning crossbow has a force of 30 kilograms, and an adult can easily pull it apart.

The power is also so-so, the lethality is very strong within eighty meters, the distance of fifty meters can pierce armor, and the power of the distance of more than one hundred meters plummets, crossbow arrows and bows and arrows are different, because there are no arrow feathers, the stability is very poor, and the power will not work after a certain distance.

However, a 30-kilogram crossbow can only be regarded as the most rudimentary, and a crossbow is usually more than 60 kilograms, and the range of the crossbow arrow will definitely be longer, and the armor-piercing effect will be stronger. In fact, a 60-kilogram tension crossbow only needs to strengthen the bow arm chord, and the main body of the crossbow machine does not need to be changed.

After Su Lun tested this crossbow machine without problems, he asked those craftsmen to conduct research and design in the base field of this crossbow arrow, this kind of research and design Su Lun did not plan to participate, if he did everything, what else did those craftsmen do, as a lord, he was very busy, and he only planned to take time to take a look at the research institute of the Weapons Bureau, and point out after encountering problems that could not be solved.

Just when Su Lun established the Weapons Bureau, the corresponding training in the barracks had already begun, and the militia system in Zhenbei City had now been established, and the militia was different from the professional soldiers, the militia was paid very low, with a minimum of five days of training per month, and the rest of the time was normal work.

The training of the militia has also changed, that is, the formation and familiarity with various passwords and flags, in fact, the training of the army is often a formation, whether it is a pikeman or an archer, he needs to know the formation arrangement.

Now the soldiers in Zhenbei City are trained in a crossbow phalanx, and when the crossbow is made, they will soon be able to form combat effectiveness, and these soldiers do not need to go out of the city to fight, and usually stay in the city for defensive operations.

Crossbowmen need to be assisted by other armies when they go out of the city, and the crossbowmen will only be lethal after forming a dense formation, without a formation, or a loose formation, the crossbowmen are completely a group of lambs to the slaughter.

At the same time, the flanks of the crossbowmen also need to be protected by other troops, otherwise they can easily be attacked by detours from the rear. As far as the current militia in Zhenbei City is concerned, their psychological quality simply does not meet the requirements. Zhenbei City now includes the security army, the regular army and the militia, the total number of soldiers has exceeded 10,000, and the total population in Sulun's territory is less than 150,000, of course, this is not counting goblins, kobolds and other slaves.

This ratio is already very high in several surrounding countries, and the military salary of the army in Zhenbei City is also higher than that of the surrounding countries, and now the finances of Zhenbei City are also a little stretched. Originally, the income of Zhenbei City was completely enough to support so many troops, but who made Zhenbei City carry out too much work now.

The biggest cost of Zhenbei City now is all kinds of projects, although many materials are produced in Zhenbei City to reduce costs, but many magic materials can only be purchased with caravans, such as magic materials transported from the Luolanvia City-State Alliance, the price will increase at least twice as much here.

And many magic experiments need to consume gold, gold is a common material in alchemy, Hathaway is also a big consumer of gold, according to the statistics of some wizards, a legendary wizard, the consumption of gold in his life is likely to be as many as several tons to more than a dozen tons.

For example, magic gold (a substitute metal for adamantite) made by wizards consumes a large amount of gold to refine each time, and Thorsilver, which is also used to replace mythril, is also refined with silver.

It would cost at least a few million jinnars to build a wizard's tower, and now that most of the wealth in Suren's treasury has been used, there are still underground gold and silver mines that are still being excavated. A large amount of gold and silver will be credited every month, and the restoration of the secret realm has slowed down now, and Suren is ready to build the wizard tower first.

Because he is ready to establish a principality, Suren is now also preparing to issue his own currency, the currency exchange in this world is very chaotic, there are more than 30 kinds of gold coins alone, and the gold content and weight of these gold coins are different, the most valuable gold coin is the wealth gold coin issued by the Church of Wealth.

This kind of gold coin is very popular on the whole continent because of its excellent production and high gold content, and the most favorite money of merchants is this kind of wealth gold coin, the front of the wealth gold coin is the head of the Fortune Lady, and the back is the badge of the Wealth Church, it can be said that it is really because of the pursuit of wealth that the Fortune Lady has a large number of believers.

It's just that perhaps because of money, the vast majority of these people are pan-believers, and the number of devout believers and fanatics is not very large, and it is really difficult for those businessmen to be speculators, and it is really difficult to make them wholeheartedly believe in a god.

The coins that Suren was about to mint were going to be printed on the wonders of the realm, and as for why he didn't print his own head, Suren felt too ashamed. And because of the technology, the avatar is not clear, of course, the wealth gold coin is rich and powerful, and uses divine assistance, but Su Lun does not have so many wizards to help make gold coins.

He is going to print the image of the Arc de Triomphe on the gold coin, and the face value of the gold coin is printed on the front of the gold coin, and he is also going to make the exchange rate of the gold coin simpler, what a gold coin for eighteen silver coins, a gold coin for thirty-six silver coins, this brain-dead exchange rate must be canceled, he plans to directly exchange one to ten, but the weight of the gold coin must be controlled, not at a loss.

The unified exchange rate can greatly facilitate ordinary people to trade and buy, and Zhenbei City must vigorously develop commerce here, and Su Lun will not deliberately make special trouble.

Zhenbei City has had the experience of minting coins before, and now it is just to exchange the coins of the Florentine Kingdom for the coins of Zhenbei City, in fact, gold coins are rarely made of pure gold, because the quality of pure gold is too soft, easy to deform and wear, so many times it is mixed with some other metals to increase the hardness.

PS: Suren is ready to establish a principality, ask for the name of the principality, Zhenbei Gong is too dramatic...
