Doomsday Bunker Upgrade

Things in Europe have nothing to do with Chen Xin for the time being after the cargo ship departs, and his daily work is now somewhat leisurely.

Although the alien attack in the Dongting Lake theater is still raging, it seems a little weak in the face of the increasingly stable defense line and the industrial strength that exploded after the adjustment of human beings.

Fighting against steel with flesh and blood, if it weren't for the tide of these alien creatures and their not weak individual combat effectiveness, I am afraid they would have been wiped out in the war.

After all, in the final analysis, this is just a group of alien creatures that are not very powerful. They are not Zerg or Tyrannosaurus, and they don't have such exaggerated combat power.

In the past, it was due to the influence of environmental factors and the fact that the industrial production model of human beings had not been adjusted, that the alien creatures had an advantage.

Of course, if the alien creatures were able to break through the blockade of the Yan Kingdom army and expand themselves, with their amazing reproductive ability, they would spread like a virus, and their number would increase exponentially.

If this really happened, it would be very difficult for the army of Yan Kingdom to deal with the alien creatures that were more numerous than ants.

Fortunately, the army of the Yan Kingdom blocked the expansion of alien creatures, and they were firmly confined to the Dongting Lake area. Even if they planned to dig tunnels from the ground, it was still not enough in the face of human beings' various monitoring methods and ground-penetrating strike capabilities. watch.

In particular, Yan Kingdom has restored its connection with the satellites in the sky. Relying on the monitoring and guidance of satellites, human military strike forces have also returned to normal levels. A large number of beyond-visual-range weapons let these guys who are still relying on physical combat know What is the track of steel rolling forward.

Although humans are not aliens crushed by the treads of tanks, there is no doubt that these aliens are crushed by creations of steel.

In fact, after the restoration of satellite communication and military satellite functions, the situation of the war with alien creatures has changed.

Previously, the satellite guidance in the missile guidance method was undoubtedly unusable due to being blocked by the dust cloud, so the military could only rely on the laser guidance and limited radar guidance of the frontline combatants, as well as the inertial guidance of the missile itself. With limited means to use missiles, the accuracy and efficiency of striking alien creatures can only be regarded as unsatisfactory.

The situation on the battlefield cannot be fully controlled, and the missiles do not know where to hit to effectively stop the offensive of alien creatures. This has led to the fact that although the military has a big killer, it can only be used within the range of aerial reconnaissance and ground observation. It is impossible to strike beyond visual range, nor can it achieve overall control of the battlefield.

It's not that missiles cannot be used without satellite navigation. As long as there are coordinates, these big killers can be launched by inertial guidance.

But in the absence of battlefield information, it is difficult to choose where these missiles should hit.

The price of a missile is high, if it is only used to bombard the cannon fodder of those alien creatures on the battlefield, it would be too wasteful.

But now, satellite monitoring is enough to allow humans to grasp every move of alien creatures on the battlefield, and no details and changes can escape the eyes of the sky.

The re-launched satellite navigation system also played a role again. As long as the satellite finds that the alien creatures on the ground have any bad tendencies, the missile will hit the target under the precise positioning of the satellite navigation.

Relying on the cooperation of the satellite, after humans restored contact with the satellite, the military has already used a wave of missiles to knock down all the underground passage exits that alien creatures can attack in the Dongting Lake area, greatly reducing the distance from the outside world. The ability of star creatures to deliver cannon fodder to the battlefield.

This has reduced the total number of alien creatures on the battlefield to a considerable extent, and also effectively curbed the reinforcement of underground alien creatures on the battlefield.

Although alien creatures can continue to dig new channels and send new reinforcements to the battlefield, under the attack of missiles with precise positioning and navigation by satellites, such reinforcements cannot achieve very good results.

During this period of time, it is not that alien creatures have tried to dig along the groundwater layer and infiltrate into the defense line before launching an attack, but human beings' mastery of the hydrological and geological conditions in this area allows them to effectively analyze aliens. Possible attack directions for creatures.

Coupled with the arrangement of the vibration monitoring system and the seismic network originally used to predict earthquakes, every move of alien creatures underground is monitored by human beings.

As long as the vibration monitoring shows that there are signs of dangerous escalation and alien invasion in a certain area, the land fleet that has been swimming around the battlefield will arrive at the area and carry out powerful force strikes to directly destroy any extraterrestrial life The possibility of breaking through the ground.

Relying on the powerful air strike capabilities of land-based aircraft carriers and the battlefield maneuverability of land-ships, the entire fleet is active on the battlefield like a mobile fortress.

Destroyers and frigates are active on the battlefield, serving as a mobile force to provide fire support for the battlefield. When necessary, they can also go deep into the enemy's rear from the air, while land-based aircraft carriers conduct battlefield inspections most of the time according to the action route planned by the military, providing air support. Strike force and intelligence support.

Wherever there are signs of gathering of alien creatures, the fleet will go there, using missiles and aerial bombs to make the alien creatures fully aware of the absolute gap between flesh and blood and steel and fire.

Of course, the alien creatures were not the ones who were passively beaten. They also made many attempts during this period, such as sending the giant fire-breathing daughters that had almost caused huge troubles to the defense line to dig in from the ground again, and then cooperated with a large number of fighting daughters to attack the defense line .

But this tactic is really simple and rough for humans.

Not to mention the missile attack system that has been deployed around the battlefield, even the frigates in the land fleet swimming around the battlefield can directly kill this thing with naval guns.

Compared with carpet bombing from outside the visual range with large-caliber artillery, the frigate can fly near the giant flame-breathing daughter, and smash the giant flame-breathing daughter's head with naval guns in a direct line-of-sight manner.

Of course, in most cases, land cruisers will not do this. Instead, they will use more methods of satellite monitoring and reconnaissance aircraft positioning, and then use missiles to kill this thing.

Only when these big guys are too close to the defense line will the land ship approach by flying in the air and hit directly with naval guns.

It is also because of this series of means that for Yan Guo, alien creatures are no longer a huge threat, but have become a controllable situation.

And as the number of soldiers killed on the defense line decreased, the military even had the idea of ​​turning this place into a round of battle, turning alien creatures into a sharpening stone for sharpening their own army.
