The number of people living around Rudburg was really large, tens of thousands, so Olaf easily recruited thousands of young men from them, and then he hired hundreds of mercenaries with money.

Although the number of these mercenaries is far inferior to those young and strong, they all have a certain amount of combat experience, and most of the armor and weapons are also very complete, and they do not need much training, and they can form a certain combat effectiveness once they are incorporated into the army.

Of course, compared with the regular armies of the same level in various countries, the combat power of mercenaries is actually weaker, and the salary is higher than that of the regular armies of various countries, that is, when the current urgent need for troops to defend the city, some lords will hire these mercenaries on a large scale, and usually mainly rely on the regular armies of their respective countries to fight.

Just after Olaf had cut down all the trees outside the city, the vanguard of the Swadia Kingdom's army arrived.

As a country with the most powerful heavy cavalry in the whole continent, the forward force of the Swadia Kingdom is naturally composed of elite cavalry, and among the five hundred forward troops, there are hundreds of Svadian knights. These heavily armored knights, once they sprint at full speed in the field, their lethality is extremely powerful, so Olaf has no intention of fighting with the opponent at all, and as soon as he hears that the opponent's army is coming, he sets the tactics of clearing the wilderness.

If the Svadian knights are the strongest field troops on the Calradia continent, then the Nord royal guards of the Nord Kingdom are definitely the strongest troops in the city war.

Whether it is besieging or defending a city, it is inevitable to face to face in the end, and at this time, the Nord royal guards wearing heavy armor and equipped with two-handed giant axes will show their strong combat effectiveness, often only a few dozen Nord royal guards can kill hundreds of miscellaneous soldiers.

When the vanguard troops of the Swadia Kingdom arrived at the city of Rudburg, they looked at the fields that had been completely burned to ashes and the trees that had been completely cut down, and they knew that the other side was ready to fight.

The vanguard did not linger long, but soon retreated, and at the same time reported the information it had detected to King Haraus.

After listening to the report of his subordinates, Haraus could only let the troops stop the advance more than a dozen miles away from Rudburg, and then cut down trees on the spot to make all kinds of siege equipment, and then they had to arrange a large number of men to be able to transport these siege equipment all the way to Rudburg.

This is the advantage of the fortified wall, it can make the enemy unable to get any supplies around the city, and even the wood for building siege equipment needs to be obtained elsewhere, which effectively delays the enemy's attack speed and buys more time for your own reinforcements.

At this time, Ye Tianlong, who was far away in the town of Odasan, did not know all this, and after having lunch with the Baron of Sol, he set out on the journey back to the camp with the people and craftsmen who had already picked up their families.

The wagons had been unloaded with goods and gifts, and now they were loaded with a large crowd of old and infirm women and children. The families of these people, because of the cruel exploitation of Baron Sol, are basically hungry and full these days, and all of them are extremely weak and can't go far at all, but fortunately, Ye Tianlong also brought more than a dozen carriages this time, so that the weakest old and weak people can take turns to rest and recover their strength.

There were more than 100 people when I went, but when I went back, the number was close to 300, and there were still a large number of old and weak among them, so it took more than three hours to return to the camp.

After returning to the camp, Judy found Ye Tianlong again and made a request to him, that is, let his son Murphy also study with Jamila.

Ye Tianlong was very surprised that Judy would take the initiative to make such a request, after all, most of the people at the bottom above Calradia are basically illiterate and don't understand the importance of knowledge at all, but Judy can realize this, and wants to let her son study with Jamila, which is obviously a very smart approach, once Judy's son Murphy can really learn some fame, then the old Judy's family is likely to soar because of his son, Since then, he has been separated from the lower civilian class.

After thinking about it for a while, Ye Tianlong decided to simply open a literacy school here for himself, after all, after he helped his subordinates pick up their families this time, there were already dozens of children in his camp, so many children, it was necessary to set up a school, after all, he was different from other indigenous lords who rode and cut the world, what he needed was not a group of illiterate lords who only knew how to bury their heads in farming, so it was necessary to open a school as soon as possible to start literacy education. At that time, the school will be responsible for teaching children who have not yet reached adulthood for half a day, and for adults to teach literacy in the evening.

At dinner in the evening, Ye Tianlong told several other team members about his idea, because they are not very manpower here, so Ye Tianlong asked these team members to take turns to go to the school as teachers in the future, after all, it is only a literacy school, Ye Tianlong and the worst of them have a reputation for showing off their talents, so it is absolutely enough to teach those illiterate levels.

And Luo Chenguang also happened to have some things to discuss with Ye Tianlong today, these days he has designed some new weapons, and wants Ye Tianlong to take the design drawings and produce some in the factory in reality to try it out, whether it will work or not.

Ye Tianlong took a look at the other party's design drawings and found that the other party had designed two kinds of rifles alone, one of these two rifles has a much longer barrel than the one that is now equipped with armed people, and the rifling is also drawn out of the barrel, this kind of shooting is used to improve accuracy.

The fact is also as Ye Tianlong guessed, according to Luo Chenguang, this is the sniper rifle he is going to equip for snipers, during this time he found that there are many good seedlings among those armed people in the training process, so he saw that he was happy, so he wanted Ye Tianlong to produce some rifles with higher accuracy as those armed people he trained as snipers.

Another kind of rifle, the barrel is shorter than the flintlock rifle now equipped with those armed people, and the caliber is also larger, the caliber of the flintlock rifle now equipped with those armed people is fifteen millimeters, which is not small, but the caliber of this rifle designed by Luo Chenguang has reached twenty-three millimeters, Ye Tianlong feels that this caliber can actually be regarded as a small cannon.

And this kind of rifle with a short barrel but a surprisingly large caliber, according to Luo Chenguang, is an extremely primitive shotgun, which can be specially used to shoot scattered bullets, and in some special combat environments, this primitive shotgun may be able to play a miraculous effect.

In addition to the rifle, Luo Chenguang, a veteran, also designed a flashbang, a small-caliber artillery that can fire in bursts, and a rocket.

This flashbang is nothing, after all, this thing does not rely on the power of the explosion to kill the enemy, but relies on the strong light emitted when it explodes to temporarily blind the enemy, so you only need to be able to figure out the formula of the modern flashbang, and then slightly modify it according to local conditions to design a homemade flashbang suitable for use in the world of riding and chopping.

As for the small-caliber repeating artillery, it is actually not a complicated thing, this thing is actually the Franci cannon, a very primitive rear-loading artillery, this kind of artillery is divided into sub-guns and mother guns, generally each gun will be equipped with five to nine guns, these guns can be pre-loaded with ammunition for backup, and take turns to load and fire the mother guns during the battle, so as to achieve the effect of rapid bursts.

However, due to the lack of manufacturing accuracy in ancient times, when the sub-gun is loaded into the groove behind the mother gun, it is often impossible to achieve a tight fit, which leads to a lot of gas leakage from those gaps when it is fired, resulting in the range and power of this kind of artillery are far inferior to those front-loading guns, at most it can only be used to kill and injure enemy infantry, if the target is replaced by those strong city walls, this thing is not very useful.

However, Luo Chenguang improved this old antique and got it out again, and he didn't expect to rely on this thing to bombard the city wall and attack the city, but originally to let his army have a light artillery that could always be carried with the army.

During this time, Luo Chenguang could also see that the road conditions in most parts of the riding and slashing world were extremely bad, such as mountain kingdoms such as the Rhodok Kingdom, the terrain was even more complex and rugged, like the kind of heavy artillery with a caliber of 100 mm that they were equipped with now, it was difficult to move quickly with the troops in this rugged terrain, so he designed this kind of light artillery with a caliber of only 60 mm, but it could fire continuously.

Although the caliber is much smaller, its advantage of being able to fire in bursts completely makes up for its shortcomings in power and range, and it can provide extremely sufficient artillery support for its own army in field battles.

And the last rocket he designed is actually not a high-tech weapon, this thing is like a large sky monkey in Ye Tianlong's opinion, but a tail fin is added to the tail to increase the stability of its flight.

However, don't look at its simple design, but because it is large enough and has enough charge, its range is as high as more than 3,000 meters, and the disadvantage is that the accuracy is very poor, and it is only suitable for dealing with those larger enemy forces.

After listening to Luo Chenguang explain the role of these new weapons he designed, Ye Tianlong nodded and agreed to the other party's request, preparing to let him produce some samples in the real factory to test them first to see if they were good or not.

Of course, to be on the safe side, these weapons will only be produced in the real world, and then brought to the Mounted Slash world and assembled one by one.

At the end of the dinner, Ye Tianlong's master Li Rufeng also put forward a suggestion of her own, that is, she felt that she could not patronize the development of these firearms just because they were useful. After all, these firearms are very primitive, and the black powder used is very susceptible to moisture. Once it encounters those bad weather, it is easy to affect its power, so just in case, they still have to prepare some bows and crossbows for the soldiers as spare weapons, and they should also pay attention to practicing some skills in this regard, so as not to use firearms, and their own martial arts will be completely wasted at once.
