At first, there were 24 runes learned from the high elves. After years of development, in the era of the arcane Empire, the number of runes published has reached 36. It is said that some runes have been mastered by the great arcane. It is rumored that in fact, the number of runes has reached more than 70.

Each Rune has its own unique power. During the period of the arcane Empire, some people even studied Rune stones, made a rune into a gem in a special way, and then combined several Rune gems according to a certain formula to make a powerful equipment.

However, the process of making Rune gems has been lost. Most of the rune equipment now circulating are products of the arcane Empire, and some are made from Rune gems excavated from the ruins.

Riddle lock is a magic sequence composed of a large number of runes in a special order. At first, the scope of human riddle lock is not large, generally only 300 to 500 meters. The riddle lock created by the high elves of the same period can cover a city.

Until the period of the arcane Empire, the mystery lock of mankind has developed by leaps and bounds, and has become the standard configuration of wizard tower and floating city.

Put away the important magic book "Enigma lock principle and making", and Su Lun took out the last architectural drawings of the remaining wonders.

[architectural drawings of Wonders: Yingling tower; after use, you can build a marvelous Yingling tower.]

[Yingling Pagoda: the Arc de Triomphe, a high tower made of iron and blood, is the final destination of a soldier. Owning this building can improve the martial spirit in the territory. Within 30 miles of the city and its surroundings, the probability of newborns having warrior quality increases by 10%. At the same time, the morale of all soldiers in the north town is + 20 and the souls of soldiers killed in battle You will enter the Arc de Triomphe, and the chance of the soul of war to become a hero is + 20. Martial spirit + 35, indestructible + 37, firm will + 35, unyielding soul of War + 28. There is a space in the hall of heroes, which can grow.]

The Yingling pagoda is not bad. It just matches the Arc de Triomphe. With the Yingling pagoda, the chances of the war soul being promoted to Yingling will increase a lot. However, the war soul stone is still needed to build this building, and there are still two. Su Lun doesn't have a war soul stone in his hand now, so he can't build it for the time being.

It's not easy to get the war soul stone. Su Lun issued the task of purchasing the war soul stone to the caravan. Now there are hundreds of caravans from all over the mainland in the north town. As long as the price is enough, someone will always get it.

After packing up the things, the banquet atmosphere in the palace was hot. Sulun was in a good mood and came to the banquet to greet the people. He stayed here for more than ten minutes before leaving the banquet.

After the establishment of the principality, sulun's life has not changed much. After all, it is only a small country with more than 100000 people, and there is no need to appoint various ministers. The caravans from various countries who came to participate in the founding ceremony of Beifeng principality also began to leave with all kinds of goods produced by the north city of the town.

Because of the celebration, sulun specially explained that the quota would be doubled this month. Now the most popular material in the north of the town has changed from sugar to toilet paper. This kind of toilet paper is not only welcomed by the aristocracy, but also the common people will buy it. Of course, the nobles bought the high-grade toilet paper which was beautifully made, the paper was soft and white, and even sprayed perfume.

When he saw the sale of toilet paper, he immediately thought of soap, perfume and other products. But when he was about to make the product, he suddenly realized that he had no idea what to do with soap. After all, he was not an engineering student in his previous life and didn't know how to make soap at all.

So only the craftsmen can study it slowly. As for perfume, it is very simple. It only needs to dissolve the perfume with alcohol. After that, it is a simple perfume. It is also difficult to make perfume. The first step is to find high purity alcohol.

The alcohol content of drinks in the world is average. For example, the alcohol content of wheat wine is similar to that of beer. It is not easy to count the alcohol height. At present, the vodka brewed in zhenbeicheng has the highest alcohol content, and the alcohol content is only between 30 and 40.

Distilled spirits are needed to get high purity alcohol, but now vodka sells well in North Town, and Su Lun does not plan to make vodka so luxurious. So I just made a few bottles for him temporarily and gave them to Hathaway.

The celebration of the founding of the people's Republic of China lasted seven days. From this year, this time of the year will become the national day. After the grand festival, everything returned to normal, and the civilians in the north of the town began their busy life again.

Businessmen seize the time to buy materials to make money. Long caravans come and go every day, and the army starts training and suppression tasks again.

Su Lun yawned and rubbed his head, which was a little sour. The book mystery lock involved too much knowledge. Now he has some difficulty in studying. Fortunately, with the talent of erudite, Su Lun's learning ability has been strengthened, which can make his learning efficiency much faster. Now he is learning mystery lock while learning other wizard knowledge.

After a little exercise, Su Lun collected the books and materials, and then got up and left the palace. Although he has become a grand duke, Su Lun still likes to wander around the city, which can make him more aware of the situation at the bottom of the city.

Many things happened during this period. Some things happened in the southern sea area. A pirate ship found the legendary treasure island. It is said that the island is full of gold, silver and various gems. The ship was brought there by a storm. The pirates recorded the channel when they left. As soon as they returned to the coast, The pirates on the pirate ship had a fierce fight.

Finally, as long as a few people escaped alive, the chart was obtained by the chief mate of the pirate ship, and the remaining pirates sold the news to other forces. As a result, many forces launched a competition. Of course, the northern wasteland is thousands of kilometers away from the southern sea area, and it has been several months since the news came here.

It is said that even the Red Dragon Queen was shocked. You know, the red dragon likes treasures very much. There are other news. For example, a Marquis of the kingdom of lorenza raised his flag to rebel and united with another surrounding country to attack lorenza. The kingdom of lorenza is now in a defensive state because of its heavy losses in the orc invasion last year.

Although these news are the latest news of Zhenbei City, the nearest one is half a month ago. Su Lun listened for a while and went to the military camp. He planned to officially recruit royal guards and establish an intelligence network in the north of the town in combination with Feiying.

In the barracks, Su Lun gathered the soldiers in the barracks. There were not many requirements for recruiting royal guards. The strength could reach level 1 or even lower. As long as the army in Zhenbei city was a regular army, the general level was level 2, and a few reached level 3.

Su Lun selected 500 people from the military camp and spent 1000 jinnars to transfer them to royal guards.

[royal guards: special arms, good at spying intelligence, collecting information, transmitting intelligence, assassination and other abilities, with additional skills: camouflage and investigation]

After the 500 soldiers selected by Su Lun were transformed into the royal guards, their strength did not change much, but they had some additional knowledge and two skills to collect and spy intelligence. Next, Su Lun built a house near the palace as the office of the royal guards.

The royal guards were also officially named the prison Secretary of the town, and allocated the first batch of 20 flying eagles to them. After these royal guards learned how to feed flying eagles, Su Lun began to send them to other countries around Beifeng principality to establish intelligence strongholds.

The 500 royal guards recruited by Su Lun are in groups of three to four. Each group carries some funds or commodities, and then disguises as a caravan or wandering mercenary to leave the north town. These royal guards will establish strongholds in some large cities.

These strongholds may be some pubs and hotels on the surface, but secretly they collect local intelligence. Once there is something important, or something he thinks important, he will pass the information back.

Part of the funds are obtained by their own operation, and the other part is allocated by Beifeng principality. After all, intelligence is very expensive. How do three or five people in a city collect and transmit intelligence? Of course, they need to recruit some outsiders. Why do these outsiders collect information for you? Of course, it's because of money. Is it difficult not to become a love of power generation?

If sulun wants to maintain a huge intelligence network, the money spent is naturally very high. Of course, Su Lun can also sell intelligence, but this operation is easy to expose himself. Su Lun hasn't figured out how to operate.

At present, there are not many flying Eagles cultivated in the eagle's nest. Except that some of these eagles are left to the investigation camp, all of them are handed over to the royal guards. Su Lun originally intended to let these Eagles breed and then cultivate themselves. In this way, the domestication effect of all the flying Eagles born in the eagle's nest is better, but the establishment of the royal guards requires a large number of flying eagles, If you want to obtain a large number of flying eagles in a short time, you can only catch hawks and falcons in the field for training.

Su Lun sent out nearly 100 royal guards teams. These royal guards teams will integrate into various large and medium-sized towns in various ways, and then establish intelligence strongholds in the towns. Each intelligence stronghold needs almost three to five flying eagles. In this way, the eagle nest needs to cultivate hundreds of messenger flying eagles.

Of course, these are only temporary. If the strongholds of royal guards continue to increase, the number of flying Eagles also needs to increase greatly. Fortunately, Su Lun didn't want to eat a fat man in one breath. The establishment of the intelligence network can't be completed overnight.
