Establish a defensive line in the dangerous passes around Koranbang, send guards or something, you don't need to worry about Jialan, although it is not a regular army, but the mercenaries of the mercenary guild have also experienced battle formations.

In particular, large mercenary groups of thousands of people, such as the Golden Two-Headed Dragon, are often hired by the lords of the city-states to help defend the city or attack the rival city-state.

And the overall management that should have been in charge of him was thrown by him to the girl deacon group of the original library book bar, and the student association of Kemo University to be responsible, in the name of exercising their management ability, and these magic elites of Kemo University are indeed doing a good job.

There is a reason why Jialan dares to let go like this, although Kelan City has suffered a great disaster, but it has also swept away the original power and power in the city, and those who survived are also members of the True Knowledge Society he founded, and the degree of cooperation is quite high.

In addition, Jialan is also the "external agent" of Kemo University, with the full support of the Mercenary Guild and the Eternal Hammer, as well as the full support of the City Guard and other institutions, the current right of the "Corland City Self-Rescue Defense Group" in Coran City can be said to be a word.

Therefore, Jialan, who has the right to mobilize all the strength of the whole city of Kelan, will naturally be extremely smooth and barrier-free.

Since the only remaining materials in the city were all controlled by the "Science and Defense Regiment" and distributed in rations, and the laws and regulations in the city were also implemented in accordance with the wartime control, the mobilization of civilians was also quite cooperative.

A large number of refugees, civilians, merchants, mercenaries, and magical apprentices in the city of Coran were all mobilized by Jialan.

First of all, the homeless refugees were hired with food for work, and participated in the construction of city defense and the construction of surrounding pass fortifications. Then summon the thieves under the name of the mercenary guild to search the whole city, block all the hidden secret passages, and prevent the enemy from invading the city through the secret passages again.

The out-of-town merchants who had lost a great deal of their possessions in the city of Corran. Jialan also came forward to appease the University of Kemo, asking for their assistance in transporting supplies to the city of Kelan by sea, and the price was purchased at a price higher than the usual two-percent.

No one thought that when the forces of all parties in Kelan City were condensed, they would have such a huge amount of power, especially the addition of hundreds of thousands of magic apprentices from Kemo University. It also made Corland City burst out with unimaginable strength.

Although among the hundreds of thousands of magic apprentices, the vast majority of them are only students in the secondary department, and they do not have the ability to fight magic. But the role they can play is crucial.

Students from the Department of Pharmacy, Alchemy, and Enchantment were transferred to the logistics team to produce various logistics materials. to supply the needs of a battle that may break out at any time;

Students of the Department of Archaeology and the Department of Sculpture. Although he is not a professional architect, the Department of Archaeology itself will involve a lot of knowledge about architecture, and the Department of Sculpture will be very familiar with various materials;

The students of the rune system and the formation department were naturally sent to strengthen the magical defense of Koran City, which was simply a kind of reborn reinforcement for Koran City...... There are not many cities. To be able to have such a large number of talents in the field of magic to help strengthen the city's defenses.

With their help. With the assistance of the thieves of the Mercenary Guild, the defensive measures and magic traps they have laid out are enough to lead the enemies who come to attack the city again, crying back!

As for the magic apprentices of the main department, they have been sent to various positions to make the best use of their resources, and the "magic battle array" that has been practiced in the underground world before is believed to be able to exert very amazing power on the battlefield.

The most interesting thing is that the earth mages are natural architects, and with their help, some of the walls that have fallen into disrepair have been reshaped and solidified, and the defenses of Coran City have been more than doubled.

Considering the lack of food in Kelan City, they spawned crops in the growing period as much as possible outside the city, hoping to alleviate the pressure of material scarcity in Kelan City as much as possible.

These were all arrangements made by Jialan in a short period of time, and the Kelai Pharmacy under his name also began to provide medicines to the Science Defense Regiment and civilians free of charge to ensure the combat effectiveness of the soldiers and the health of the civilians.

The Doom Fort under the name of Jialan played a vital role in it, not only fighting with Koran City, clamping down on the back road of the war goblins, but also sending a dwarven blacksmith master to create and repair weapons, equipment, and city defense equipment for the "Science Defense Regiment".

Fortunately, the main looting in Koran City was weapons, equipment, belongings and food, but all kinds of raw materials were not packed and transported by the goblins because of the inconvenience of transportation on the battlefield.

It is estimated that these materials that are difficult to take away, and the war goblins plan to deal with them when they withdraw their troops or retreat to Koran City, so the magic logistics team and the dwarven blacksmith team will not be difficult for the clever woman to cook without rice.

As for the True Knowledge Dragoons who belonged to Doom Castle, they had become an important force in Koran City, and their importance even exceeded that of tens of thousands of mercenaries and tens of thousands of city guards.

The True Knowledge Dragoons, who once annihilated the war goblin legion besieging Koran City, have become a source of confidence and stability for Koran City.

It is precisely because of the existence of this group of mysterious dragon knights, whether it is civilians or mercenaries, that they all show a high degree of cohesion and confidence, believing that even if the war goblins attack again, Coran City will be able to withstand the attack of the war goblin army.

Due to some "reason" that could not be said, Jialan only supported 500 sickle-clawed drakemons and 500 sharp-toothed drakemons to the scientific defense group, and was driven by the mercenaries of the Golden Two-Headed Dragon Mercenary Regiment to form a light armored dragoon regiment and a heavy dragoon regiment, which were used as mobile troops to support the established passes and defense lines at any time.

As for the remaining dragon skeletons and golden skeletons, which numbered about 5,000, they were stationed between Koran City and Doom Fortress to prevent the follow-up troops of the war goblins from breaking through.

It is precisely because of the mobilization of the whole city that all matters have been settled. So Jialan, who has picked himself out, can hide and concentrate on studying something, in a certain nature. He's just as bad as the old magicians at Komo University, isn't he?

The previous test of "flying ball" in Kemo University only verified one of Jialan's assumptions, because in the exotic memories in his mind, there was something similar to a dwarf float boat, called an "airship".

But to build an airship, you need something called hydrogen. This is an elemental body that Jialan doesn't understand, and I don't know how to find the "hydrogen" element, if you carefully consult the knowledge hidden in the foreign memory. If you dig deeper, you might be able to find the answer.

But the amount of information contained in exotic memories is so huge and profound that most of the exotic memories are incomprehensible and unimaginable to Jialan. Trying to figure it out. It's definitely not something that can be done in a short period of time.

So I can only choose the next best thing, which is simpler and can barely be understood by Jialan, "hot air balloons".

The exotic product of "hot air balloons", as the name suggests, is that the gas element needs to be heated by the fire element, so that the fire element and the gas element have a "compatible" reaction.

However, according to Jialan's understanding of the elemental system, the gas element is the "inner element" that is most likely to react with other elements.

Therefore, the elements of air are often mixed with the elements of water, while the elements of fire and water are "repellent" each other. If the fire and water particles are of equal mass, a "neutralization" reaction will occur. "Deformation" occurs and "vapor side elements" are formed!

However, the "steam side element" is definitely not the reason why the flying ball can fly, after all, the "steam side element" is rich in both "water and fire", and the water element in it will increase the weight of the object.

Therefore, judging from the process and results of the experiment, it seems that the fire element repels the mixed water element in the gas element, making the gas element "lighter" to reduce the weight.

Jialan has not yet fully understood the principle, but it does not prevent him from comprehending the "neutralization reaction" of the pure fire element and the gas element, which may derive a "deformation reaction" that is different from the fire element and the water element, and produce a new element of "sexual transformation reaction".

Since this new element is derived from a series of "repulsion and neutralization" reactions between the fire element and the gas element, Jialan intends to call it the "fire and gas subelement" first!

The "fire gas subelement" is lighter than the "steam side element", which may be the reason why the flying ball can gain "stagnant buoyancy" and thus float.

It's just that the "fire gas subelement" is extremely easy to be eroded and collapsed by other elements in the outside world, so in order to continue to obtain this "stagnant buoyancy", it is necessary to always maintain the "sexual transformation reaction" between the fire element and the gas element, which requires a continuous combustion fire source......

Jialan made a miniature flying ball by herself in the laboratory, and while constantly conducting floating tests, she wrote and drew on the manuscript paper to calculate.

He had planned to imitate the pygnome's olive-shaped float and design a pike-shaped sealed fishskin pouch, after all, the shuttle-shaped pouch was more conducive to flight, less hindered by wind in the air, and faster.

Therefore, he first used feather iron to weave a shuttle-shaped net cage, and then covered the cage with deep-sea fish skin to isolate the invasion of external elements, so as to maintain the durability of the "fire qi sub-element" in the fish skin pouch.

But what disappointed him was that in the "One-Yuan Single-Phase Fire Element Conduction Rune Array" built in the center of the cage, the core of the "Fire Source" was put in, and a fire element magic crystal unique to this era was put in, which made the magic circle start to operate.

Jialan found that when the fire element and the gas element have a "sexual reaction", the "fire gas sub-element" in the fish skin pouch will be reduced by about 20%~30%, and it seems that some substances are burned off by the fire source, which causes the sealed fish skin pouch to wilt down, and the air buoyancy will be greatly reduced.

This shattered his idea of doing it once and for all, and he had to redesign a valve at the bottom of the fish skin bag, and add the "One-Yuan Single-Phase Wind Element Conduction Rune Array" and the Wind Element Magic Crystal to facilitate the infusion of the wilted air bag.

It took a long time to revise and revise, and Jialan finally successfully completed the design, but the finished version of the design drawing has become completely different from the initial idea.

Without taking a break, Jialan immediately summoned his dwarven blacksmiths to create two shuttle-shaped feathered iron cages with a length of 75 meters, a width of 20 meters, and a height of 20 meters.

Inside these two super huge row cages, a multi-node fire source array is arranged in a three-dimensional grid shape, so as to complete the "gas element deformation change reaction" in the shortest possible time, so as to quickly obtain "air buoyancy".

At the same time, you can also control the fire source circle inside the airbag to be ignited and extinguished through the console that concentrates all the conduction rune lines, so as to increase or decrease buoyancy, and go up or down.

To achieve balance and speed, Jialan added a pair of wing-like balance wings, a swordfish-like dorsal fin, and a crosstail to ensure that it was as stable in the air as a flying arrow.

But this led to the strange appearance of the cage after the skin of the deep-sea fish, it looked like two super giant great white sharks with two heads hooked on their backs, and the strange face of Jialan simply summoned a group of totemic magic apprentices, using magic dye, graffiti on the skin to create a bloody mouth of the fierce great white shark paint.

However, light can not float, Jialan does not plan to install cumbersome sails for the "great white sharks" like the gnomes, so she has to design a "wind jet" device, which is installed on the wings, tail of the great white sharks, and some key positions that can be adjusted in direction.

The so-called "wind pipe" is actually a binary single-phase conduction rune array with "Wind Creation" engraved on the inside, and it is powered by silver-level wind element magic crystals to drive the circle to continuously release the second-order plastic energy system "Wind Creation", forming a backward driving force to drive the "Great White Sharks" to fly forward.

With the continuous addition of various energy supplies while construction, the "flying ball" in Jialan's original plan has become a huge project, and it is impossible to build in large quantities in a short period of time, which is contrary to the original intention of raising materials in a short time.

Just when Jialan had to simplify the design of the magic linkage floating platform named "Storm Shark", and returned to its original intention, first designing a simple, small, and cheap flying ball to come out for emergency, the president of the Flash Gold Chamber of Commerce, "Golden Jewel" Ding Bao Belen, finally came to the door!

"Gal is on top! What the hell is this?"

A group of dwarf dwarfs surrounded the behemoth in front of them, constantly exclaiming. (To be continued......)
