readx;? The huge magic barrier shrouded the front of the city wall, and the catapults of the coalition army almost all returned in vain, and it was the undead legion that issued these magic barriers, oh no, it should be said that it was the product of the birth of the communication between the forces under the royal road, of course, although it was said that there was an interconnection, but neither side had seen each other, and even who the other party was, what kind of force it was, after all, the existence of the undead legion would still make many living beings unacceptable!

Therefore, the so-called technical exchange is actually Wang Fan sorted out the research materials of the alchemy technology and magic energy technology of various forces, and then summarized them, eliminating those that are duplicative or unsuitable (the research direction of the undead has a lot of conflicts with other forces, after all, the needs of the undead and the living are different!)

And these magic shield emitting machines are one of the products born after the exchange, its technology covers the magic crystal application technology from the undead, the magic energy shield technology of the elves, the mana link technology between the trolls and the human empire, etc., although it looks very fragmented, but when the technology comes together, a new protective weapon was born, of course, this is only a protective weapon developed by the undead, and in the hands of the elves, it has become a different appearance, here is not fine for the time being. lā

With the end of the Bright Bomb offensive, although disappointed because they failed to achieve the expected results, the coalition still launched an attack, they were like gamblers who pressed their own capital and planned to gamble, if the bet won there to make a lot of money, if they lost, at least they could keep their current foundation, so the coalition naturally began to give it a go!

It's a pity that the ideal is beautiful, and the reality will teach you how to be a man, when the figure of the coalition forces rushed to the city, what awaited them was the double attack of the goblin mines that had already been activated and the air cannon filled with the wind attribute magic crystal (the meat grinder could not attack the enemy at the foot of the city wall because of the problem of shooting angle)

The first to start blocking the coalition forces is not the goblin mines, but those medium-range air cannons, although the goblin mines are the first line of defense, but after all, the goods are dead things that will not move, so the first to attack is the air cannon that can hit the distance!

The charging of the air cannon has long been completed, just wait for the order to be issued and immediately fire, although this thing is the product of alchemy machinery, but it is far inferior to the meat grinder, because the meat grinder can adjust the height distance by itself without human operation, and then fire, while the air cannon is not, someone must control it to control it before it can be aimed at the target and launch, otherwise, this thing may not even be charged automatically, and this is the difference between the alchemy puppet and the alchemy machine, although the name of the puppet is not good, but it can have a certain degree of autonomous action, but the machine is completely a dead thing, so the gap in technology content between them is quite large.

However, no matter how to say it, the air cannon will still become the main development direction of the next stage of the undead legion, and even the research and development resources of weapons will be moderately inclined to it, although the air cannon can only be used in the plane, and it will be weakened in the void (there is no air in the void, let alone wind), but at this stage, in addition to the gods, only those ancient starry sky monsters wandering in the void are the only ones, so in view of this situation, the undead naturally do not need to invest valuable resources in the development of void weapons now.

After all, whether it is a god or a starry sky beast, it is the existence that the undead can't beat even if they use all their resources to develop the void weapon, unless your void weapon is really powerful enough to kill everything in seconds, otherwise in the void, they are the masters, plus the undead army is now fighting in the plane, the void is not involved at all, and the door of wailing (the door of darkness) is only a void teleportation based on subspace, so there is no need to worry about such a problem at all, just like we ordinary people don't have to worry about the progress of the China Space Agency, because the level is not enoughWhat the hell are you doing with that mind?

The fury of the air cannon is indeed worthy of being selected by the undead to become the main weapon for future development, and the wind bullet it fires is like a cyan glass marble, which looks as small and insignificant, but when this seemingly inconspicuous green marble is shot out of the cannon chamber, it immediately rises against the wind, in fact, even if there is no wind, it will expand, because this green marble is actually a highly concentrated wind attribute element energy formed after being extracted from a large number of magic crystals and compressed!

And in the process of expansion, the spiral force carried when the cannon chamber was fired began to take effect, and a rotating cyan vortex began to form, and at the same time, a large number of wind elements around it were also forcibly pulled into this terrible cyan vortex, and then when the cyan vortex landed on the head of the coalition army, a tornado was formed, although it was not that kind of super-large tornado, but don't think about this little thing, in fact, the real composition of this tornado is not a violent whirlwind but a more violent spiral wind blade!

It can be said that the entire tornado is a large number of ultra-sharp knives spinning wildly at supersonic speed, if it is hit, unless it is the kind of ** really strong to be ridiculously strong, otherwise a thousand knives are the only fate of the hit, think about that scene, you can understand why the undead army will choose it as the main weapon for future development.

And soon the coalition army used its own life to provide new data for the weapon test of the undead legion, after all, although the principle of the air cannon is based on the principle of the toy air cannon on the earth to a certain extent, but in this world with magical elements, the air cannon has long been mutated, so the data needs to be collected by themselves, and the data measured by the coalition army is naturally the best, after all, the light is against the monster, The data measured by the desolate beast is only for beast-like creatures, and the data of humanoid creatures is impossible to obtain, and the data of the natural coalition is naturally better, after all, there are pure humanoid creatures of ancient humans in it.

And with the landing of the Tornado Blade, the coalition soldiers immediately felt its power, they are not fools, such a battle is not unseen for them as the elite of a hundred battles, so they judged the danger at the first time, but unfortunately it is one thing to judge the danger, but it is another thing to dodge, after all, this time the air cannons that came over were not only one or two, but a salvo of 2,000 air cannons!
