Since the Aisinger Mobile Fortress is a war fortress, there are naturally many defensive and offensive weapons on it. The mysterious lock mentioned in gold coins is actually a kind of urban defense system. This thing is the same as the protective cover of the general system of cities. The only difference is that this protective cover is a little special.

Generally speaking, urban-level protective covers can be divided into many different levels according to the size of the coverage range, but this is actually of no practical significance. In addition, urban protective covers can also be divided into four different levels: low-level, ordinary, advanced and super through different energy intensity. Of course, this is just a rough classification and not very accurate. This classification is directly related to the protection ability of urban protective covers. Low-level protective covers are easy to penetrate, and advanced ones are much better. Of course, the protection level is directly linked to energy consumption. Although the energy consumption of advanced urban protective covers can also be reduced by changing the design method of the magic array and installing auxiliary magic arrays, just like high-power cars usually have an ultra-high fuel consumption. You can reduce the fuel consumption of large-power cars through turbocharger technology and lightweight car bodies, but no matter how you reduce a medium-sized truck, it is impossible to save fuel than a mini car.

The same goes for this. Advanced urban protective covers have excellent protection capabilities, but their energy consumption is also scary. Moreover, advanced protective covers are not simply high energy consumption. High energy consumption means high magic density. This requires the magic protection device to have super high tolerance and must have a strong energy-gathering effect, otherwise such protective covers will not be supported.

In addition to the protection strength classification, urban protective covers also have some other categories, such as whether there is auxiliary energy. In addition, there are three more meaningful categories. The first is to see whether the protective cover is active protection, the second is to see whether the protective cover is one-way protection, and the third is to see whether the protective cover has overload resistance.

For a city protective cover, the active protection system is far better than the passive protection system, because the passive protection cover is manually opened, and once activated, it will be kept open unless someone closes it or runs out of energy. Although the protective cover will consume a lot of energy when resisting attacks, this does not mean that it will not consume energy when no one attacks it. It just is much less energy in this case. However, as a protective cover that can cover the entire city, just think about it and know that even if this thing is not high in energy consumption in normal times, it is definitely a terrifying number. It cannot be really cheap enough to ignore it. If that is true, the cities in the game should always have protective covers open. The actual situation is that unless a siege battle occurs, no one will start the protective cover.

Because the protective cover starts to consume energy as soon as it is started, the passive protective cover is obviously a money-burning machine. In contrast, the active protective cover is much better. The active protective cover is actually two layers of protective covers that are tightly attached to each other. The outer layer is extremely weak. It can almost be said that it is in the startup state if there is anything or nothing. However, because its protective strength is almost zero, its energy consumption is negligible. Even just an ordinary energy-concentrating array can automatically complete the energy cycle without additional energy consumption.

This weak protective cover is the sensor of the active protective cover. When an external attack passes through the first layer of shield, the second layer of real powerful shield will be instantly activated. The starting speed of this powerful shield is very fast, and it can be guaranteed that even a beam attack can be intercepted. When the attack is over, the second layer of protective cover will be closed immediately. In this way, the second layer of high-energy protective cover will only start instantly. Once the attack is over, it will shut down immediately, and it will never waste a trace of energy.

Of course, everyone likes this perfect design, but in fact, this kind of thing is not something that everyone can have. As for the reason... it is mainly impossible to do it.

Currently, only a few guilds, including our Frost Rose Alliance, will have the production capacity, and although the main system cities in various countries are also sold, you must first interact with the managers of those cities, and then brush your relationships. Only after the relationship status is upgraded to the "warmly welcomed" state can people sell it to you. Of course, even if you have something to do, you won't be able to buy it, because the system actually has restrictions on this, so after the relationship level reaches it, it's just that the NPC in the city will talk to you about this.

It doesn’t mean that you will definitely get active city protective covers. Usually in this case, the NPC in the city will tell you that there are certain difficulties in making such city protective covers. They either lack materials or require some technology. Anyway, they will send you a task. You can only buy active protective covers after completing the task. If you fail, don’t say anything. Of course, there is another limitation in the end, that is, you have to have enough money. Relationships belong to relationships, and business belongs to business. Even if others are willing to sell them, if you don’t have money, the NPC in the system city will not be given credit to you.

The second important category of urban protective covers is whether one-way protection is one-way protection rather than two-way protection. It seems that two-way protection has one more protection direction than one-way protection, but in fact you can understand it by thinking about it. The protective cover will form a complete enclosed space after being activated, so the protective cover actually has only two sides - the inside and the outside. The so-called one-way protection means only external protection. When people outside attack the city, they will be intercepted by the protective cover, and people in the city will not be affected in any way. However, if your

The protective cover is two-way, which is troublesome. Although the enemy's attack cannot enter, your counterattack cannot be out. Moreover, whether it is an internal and external attack, it is an attack, and it consumes the energy of the protective cover. If it is an active protective cover, it is nothing. You can completely prevent the protective cover from being activated by manual control or the installation of control modules. The time difference can prevent the external attack from being affected. However, if it is a passive protective cover and is bidirectional, it is bad. Apart from the enemy's eyes, you can really do nothing.

The last category is whether the protective cover has overload resistance. This actually means whether the protective cover can remain intact after it is broken down. A protective cover with overload resistance will only allow the attack that penetrates it to pass through after it is broken down. As long as the energy core has energy, it can continue to protect the attack after it is broken down. Even some advanced models of overload resistance can only lose their protection ability at the point where it is broken down at the same time, while the protection power in other locations still does not decrease. You must know that this ability is very abnormal. Because a city is so large, there must be more than one point that is attacked at the same time, so if a perforation in one place causes the entire protective cover to collapse, even if it is repaired immediately, at that moment, the attack at other locations has already penetrated, which will cause protective loopholes. Therefore, the protective cover that can resist overload and will not collapse as a whole after being broken down is the best urban protective cover.

The Midlock Shield of our Aisinger Mobile Fortress is a multi-protective fusion shield, and its body can no longer be regarded as a protective shield.

According to the above classification, our Midlock Protection System can be regarded as a super-large-scale, ultra-high-strength, active, one-way, overload-resistant, and multi-point hybrid protection super-protective shield. Moreover, in addition to its many characteristics, it has one unique feature, that is, protection diffusion.

The general protective cover, no matter what classification it belongs to, is just a thin light film at the moment of protection. Our Mikaku does not have this light film, but turns the light film with almost no thickness into a large fog covering the entire city and surrounding areas of the city. This large fog is our protective cover. It is not a thin layer. On the contrary, it is not only thick, but also terrifyingly thick.

A general protective cover can only provide one-way protection at most. Once the enemy enters the inside of the protective cover, the protective cover will lose its effect, because there is no protective ability inside the protective cover. But our Mika Lock is not. It cannot be simply one-way or two-way protection, but should be said to be human protection. As long as it is an enemy's attack, as long as it is under the fog, no matter which direction you launch an attack, it will be protected. If it is an attack from our own people, no matter which direction you attack, it will not be affected. Therefore, Mika Lock's protection ability is simply against the sky, because it can still provide protection even in the event of urban street fighting.

Of course, because a thin layer of protective cover is spread over a large fog, the Miku Lock also has a defect, that is, the protection strength must be increased by distance.

If the enemy launches an attack outside the protective cover, no matter what type of attack it is, it will immediately start to weaken as soon as it touches the protective cover. However, it will not be blocked instantly like it touches a normal protective cover, but will continue to move forward, but the attack will continue to decline until the attack power drops to zero, and the attack will be completely intercepted. However, this process is not completed instantly, so if you happen to be on the edge of the protective cover, or if the enemy is inside the protective cover and the opponent is attacking you, the Mi Lock Protection Cover can only provide very limited protection. However, considering the advantages of the Mi Lock Protection Cover, this defect is actually nothing. In terms of protection strength alone, it can completely surpass those crystal bubble-like protective covers.

In fact, in addition to the protection, the Miku Lock protective cover also has two very powerful abilities. One of them is to disrupt the sense of direction and obstruct the line of sight. The base is like a ghost hitting a wall. Once any enemy enters the range of Miku Lock, the vision will be seriously affected and the sense of direction will disappear. Therefore, most enemies will feel like they enter the formation after entering. Now the Siberian gods are wandering around there, but in fact they are controlled by the Miku Lock's ability to obstruct.
