In the cave 500 meters underground, many arms flow continuously, and various arms also have different forms.


    The engineering arms are generally ferocious and have no wheels. Instead, they are six insect like mechanical legs with hooks and claws at the end that can climb on steep cliffs,


    They in charge of engineering construction need to work in complex terrain, so they need amputation that is more flexible and easier to adapt to complex terrain.


    This can be seen from the fact that animals with wheels have not evolved in nature. The structure of wheels is not suitable for the complex terrain of nature.


    There is a high-power laser on the back and abdomen of the engineering soldier, which is responsible for cutting rock strata. Although it is engineering equipment, it can also be used in close combat in case of emergency.


    Because it is engineering equipment, the power is often high, and the attack power is much higher than the light edge tank.


    Compared with the engineering vehicles with mechanical legs, most of the arms in charge of combat adopt the design of crawler or solid rubber tires. It is not that they can not use more flexible mechanical legs, and there are no technical problems at all.


    However, the structure of the mechanical leg is complex, and there are more parts. More parts often mean that it is more prone to failure and damage, and the production hours will be longer. Compared with the advantages brought by more flexible actions, these shortcomings are more unacceptable.


    To put it bluntly, the mechanical legs are not strong enough to withstand operation. There is no need for exquisite works of art in the unlimited explosive flow. The more stupid and thick they are, the more suitable they are for the battlefield with cannon fodder. The design idea of Mao equipment makes these chariots extremely reliable and the production hours extremely short.


    The complex underground world is expanding rapidly in a short time.


    On a snowy night, after sending a reconnaissance plane to scan without results, he realized that interference detection equipment must be used in underground facilities, which is the most troublesome situation.


    We must send a large number of reconnaissance aircraft to drill the ground and recklessly enter the enemy base. Only when we recklessly enter the shielding area can we find the hiding place of the combat base vehicle.


    Hanhai Xuanqi can arbitrarily form various forms of UAVs. If you want to explore the ground, the shape of these UAVs will become shuttle. Unlike pure scientific and technological equipment, their design does not need to fully comply with the normal scientific and technological principles. As long as it is almost OK, Hanhai Xuanqi will make up for the imperfections by itself.


    This makes it possible to temporarily design a ground drilling UAV in the battle. Thousands of shuttle UAVs fall from the sky, and the drill bit on the head rotates at high speed, just like a ground drilling bomb, falling into the ground.


    On the light screen in the hands of snow night, the data of each ground drilling UAV is displayed.


    In their exploration, the ground floor was all uniform soil, without any trace of excavation.


    But it was clear in the snowy night that it was only camouflage. It was some kind of equipment that blocked his detection, just like the anti black in the red police. He could see the situation inside only when he entered the shielding area.


    What he is doing now is like releasing spy satellites and opening a full picture view. In this way, excluding places without black prevention, all places with black prevention are enemy bases.


    The ground drilling UAV dived rapidly and soon reached 500 meters underground. At this depth, the UAV began to lose contact inexplicably.


    The snow night recorded the location of these lost UAVs, and fuzzed the location of all lost UAVs. Soon, an underground map was obtained. A large number of UAVs disappeared in pieces. There is no doubt that it was connected to the local base.


    What he has to do is to level these bases as quickly as possible.


    We must eliminate these base vehicles as quickly as possible, otherwise if they are allowed to increase in value, there is no chance of winning at all.


    In contrast, the filming strategy is much simpler. Throw down the base car and let them take measures according to local conditions. Just take care of explosive soldiers and unlimited explosive soldiers. When explosive soldiers reach the field of vision, 80% of them are covered by their own soldiers. In the past, F2a has simple operation and does not burn the brain. It is really a mudslide in the real-time strategy game.


    As the defensive side, the difficulty is obviously lower than that of the offensive side, but the snowy night must attack. The dark Qi of the Han sea is not a real machine after all. Even if it condenses again, it does not mean that there is no consumption, and it will only be less and less in the end.


    But the base car is different. It is real material. If you copy yourself once, it will double. If you don''t curb it, there will only be more and more.


    After finding the underground shielding area, the snow night immediately condensed a large number of ground drilling machinery with the mysterious gas of the vast sea, excavated the tunnel and went straight to the base car hiding underground.


    Compared with the silence of the base vehicle when digging holes, most of the things made in the snowy night are moving. The rumbling sound is like thunder. The huge shield machine excavates a large amount of soil underground and accumulates on the surface to form a huge mound, which is frightening.


    The shield machine is like a terrible underground worm, pushing firmly towards the ground. Open up a passage to the underground.


    It''s helpless to open such a large channel. The Hanhai Xuanqi itself floats in mid air, that is, most of the powerful units condensed by Hanhai Xuanqi are flying units.


    It is almost impossible for these gadgets to adapt to underground operations. Relatively heavy ground units can only go underground along thick passages.


    The only advantage of Hanhai Xuanqi is that it has an overwhelming quantitative advantage at the beginning.


    The mighty army penetrated the rock stratum, broke the sky of the underground base and fell from the sky.


    The first wave comes with a large number of explosives, just like exploding mouse holes. The power of explosion will be greatly improved in a closed space. If you can blow up here, the follow-up troops behind will not need to follow up.


    Boom!


    Boom, boom!


    Successive explosions sounded at the end of the tunnel, but the explosive impact recoiled up along the channel, and even crushed a large number of shield machines parked in the nearby tunnel.


    The bomb hit the shield, and in each layer of the shield, there was a layer of physical defense. The defense was spherical as a whole, and the surface was temporarily plated with aidman alloy coating.


    After the energy shield was blown up, this layer of physical defense withstood most of the explosion impact. Before it was torn up, it protected the fragile facilities inside the base and bought time for the armed assembly in the base.


    Production facilities have entered the tunnel and started to transfer, leaving only arms with combat capability. The mother nest that cannot be transferred began to change the type of production.


    A large number of arms similar to self exploding trucks have been produced. The vast sea Xuanqi army on a snowy night is completely unaware that once they successfully attack this underground base, they will be greeted by the art of sticking to their faces.
