It also includes a suspended surveillance ball launched by Du Le.

This kind of surveillance ball can float at an altitude of one thousand meters and remain motionless, but at the same time it can monitor specific places and targets. Correspondingly, through special program settings, the operator can conduct ultra-long-distance surveillance.

Surveillance mission. This so-called ultra-long distance means that the surveillance range can even reach a radius of one thousand kilometers.

This kind of surveillance ball, introduced by a trade fair salesman, has also become an early warning tool. Countries can purchase multiple surveillance balls and deploy them in their own airspace.

Compared with previous early warning aircraft, surveillance balls have several advantages.

The first advantage is that the surveillance ball can work continuously for up to a month without interruption.

The second advantage is that this kind of surveillance ball has a high self-protection ability and can withstand adverse external factors such as lightning, air pressure, and interference.

The third advantage is that it can be suspended and stationary, and remotely controlled from a very long distance, which greatly reduces the possibility of being discovered by the enemy.

After combining these advantages, this surveillance ball can also perform tasks according to certain intelligent programs, and can even automatically avoid single attacks such as bullets, artillery shells, and even laser rays.

Therefore, as long as these surveillance balls are deployed around alien bases, all countries around the world can gain the advantage of obtaining military intelligence in a timely manner. Of course, the premise is that aliens cannot be discovered.

Du Le also launched a military wireless walkie-talkie at the trade fair that is based on a virtual network and can be used over long distances. However, Du Le does not intend to mass-produce this wireless walkie-talkie.

Production.

Because, so far, smart factories have no extra space that can be provided to Dule to build extra production lines.

Therefore, Du Le just brought a hundred virtual wireless walkie-talkies. Du Le thought that as long as representatives from each country could purchase one or a few, it would be able to ensure that the military between countries could

In subsequent battles with aliens, they can use this wireless walkie-talkie to communicate with each other privately and coordinate military operations. This can even reverse the situation and gain a certain amount of initiative.

After all, the current communication system of the earth has been destroyed, and the virtual network is bearing a heavy burden. Therefore, in the coming days, whenever countries encounter something and want to communicate, they must enter the virtual network game "battle"

". There are too many redundant actions, and communication is not very convenient.

Therefore, especially for certain urgent military developments, this virtual wireless walkie-talkie can ensure timely communication.

In fact, Du Le hopes that all countries can have this kind of virtual wireless walkie-talkie, so that the Earth Defense Force can contact various countries to obtain better intelligence support. Of course, Du Le also has his own selfish motives, which is to hope that all countries can use the island country as the core
