The maneuver mode of the armies of this world is a little different from that of the earth, the super transport aircraft carrying a large number of combat mechas, the shadows cast on the ground, can't help but look up, the super delta-wing fighters, floating in the sky, the engines on both sides of the plane are the size of trucks, driving huge propellers, driving powerful air currents, flying in the sky,

The largest transport aircraft that the Republic of Dawn can currently make, this kind of transport aircraft can only transport mechs, so there is no wide cabin inside, so the plane looks very compact, and about twenty-five manned mechs are embedded in the carrier compartment, just like batteries are embedded in the battery compartment.

A total of fifty aircraft, forty of which are such fighters for transporting mechs, can transport about a thousand mechs, for the transportation of an armored division. The current armored division of the Dawn Republic is composed of 1,000 mechs, and it is also the only transport group that can transport an armored division to the target area with the fastest force. This is the fastest transport force. The second-level transport force is a large propeller carrier aircraft similar to the Dandelion missile launcher, and such a transport force can maintain the capacity of twelve armored divisions in the Dawn Republic. As for mass transportation with the next level of speed, it is the airship transport force of this world. Of course, if airships are used for large-scale transportation, it will be a total war.

Compared with tanks, if the combat effectiveness of the combat mecha is on the plain, when the land mecha and the tank cluster are one-on-one, they may not have an advantage, just like the special forces may be hit and killed by a QQ car on the main road. But the battlefield is changeable, and the special forces will not stand in the middle of the road and fire at the QQ car cluster. Tank clusters will also not appear in front of mechs, and now that the Dawn Republic's sky attack system is gradually improving, ground battles on the plains must be concealed under aerial firepower. On the contrary, in the mountains and in the city, such a battle mech wrapped in heavy metal plates, walking in the streets, can easily crash through the fence, and even kick a hole in the wall, worthy of the armor power. And in human form, firepower flexibility is a nightmare for all soft targets.

Such a reorganized division, transported by the fastest means of transport in the Republic of Dawn, arrived at the position of the drilling site in the northern territory of the Republic of Dawn, and at the same time about ten divisions of armored forces, multi-propeller carriers, in the roar of many people in the Republic of Dawn, moved towards the north under the surprised gaze of many people in the Republic of Dawn. Such a huge military force mobilization made everyone ask a trace of unusualness.

This is the huge military strength that the Evolution Officers of the Son of Heaven Alliance can mobilize in four days in this world, and all the colonels' bases are not worth mentioning in the face of the real military strength of the only industrial country in this world. If nothing else, this century is the advent of the Red Police base, and even if the nuclear bomb is not used, it will be a scene of drawn. To use a nuclear bomb? Nor is it a scene where the Red Alert base can turn the tables, and the space surveillance network is gradually improving, unless the underwater nuclear submarine dives into the position near the coastline and suddenly rises to the surface and launches. No land-based launch vehicle will survive.

With such a strong military strength, there is not even a test knife on the surface. Such an advantage had already been formed when the colonel entered, so after Marshall and the others came in, they kept their heads bowed and accepted their fate until today, and they couldn't get up. At the same time, the strategy could not be played, and it could only be controlled by the Heavenly Son Alliance represented by Wang Long.

The surface of the earth, which has been secured by such a powerful military strength, is now impossible to have a large-scale war, and the battlefield is far away from the surface. The battlefield of choice for such military power in the future is underground.

The order of the officers of the Son of Heaven Alliance to move north is now being carried out.

Ren Di stepped out of the plane and stepped on the sandy ground, which was a rare appearance outside the non-industrial zone in the past two years. Also appearing with Ren Di was Wang Long, neither of whom was wearing a mecha. For Ren Di, now Ren Di's perception is strong, and any wind and grass around him, Ren Di can clearly feel that if he wears a mecha, his whole body is wrapped in steel. Although the blood was a little thicker, the keen perception was obscured. On the contrary, the gains outweigh the losses.

As for Wang Lung? Wang Lung followed Ren Di to protect Ren Di. It is necessary to understand the wind and grass within the target range of Ren Di's line of sight, so Wang Lung did not wear a mecha. The two of them arrived at the underground drilling site of what was already a military station, in no particular order.

Both sides, accompanied by heavily armed soldiers and five battle mechs, quickly arrived in jeeps to the site of the drilled cave. After all, gasoline-fueled engines have been developed when the world's coal-to-oil technology is mature. As for the turbofan engine, research and development have also begun. Not for fighters, but for the development of cruise # missiles. As for the low-end fossil fuel engine, as a power source for small vehicles, it has gradually developed under the market demand.

When Ren Di and them arrived, these cavemen were very curious to see the arrival of these big people, and at this time, a conscription researcher walked up to Ren Di and Wang Lung to introduce the current situation after showing his identification.

Now there are a lot of wells drilled in the north, but the drills are drilling a passage of no more than one meter to the ceiling of the underground world, and it has not been expanded, this kind of small cave is very inconspicuous above the underground world, before expanding this passage into a transport drill, but carefully exploring the situation of the underground world. An unmanned probe needs to be sent in first. Then send in an advance team of cavemen. Finally, expand the drilling and send troops in, this is the classic process of the underground alliance to expand in the underground space piece by piece with the help of the surface.

This set of processes is invincible in the underground world in the south of the continent, and the armies of the entire underground alliance appear in various underground spaces like opening portals, gaining a huge advantage in strength in a very short period of time.

Now the Celestial Alliance and the Knights of God expect this situation to be replicated in the north. Now, after being introduced to the conscripts on his side, in a makeshift dark room near the drill, the space door opens, and Colonel Alice walks out of the space door. As the executor of the underground strategy, Alice has levies near various drilling wells on the surface, and as long as there is enough electrical support, the space gate can support Alice to appear in various drilling areas. Of course, the premise is that you have your own levy to provide the coordinates, and the energy supply portal can be opened.

Alice, who had arrived from other drilling areas, had a very unsightly face. Without saying a word, he directly invited Ren Di and Wang Lung to walk into the portal. Under the power delivery of the elemental fuel rod engine's electric switch, the swarthy portal suddenly expanded.

Ren Di cautiously stepped into the portal. There is no passage in the portal, and behind the portal is the solid concrete floor of the target location, where Alice's levies and Wang Lung's levies are already waiting in the warehouse. After Ren Di walked out on his hind feet, Wang Lung and Alice came out on his heels. Ren Di suddenly made up his mind, what would happen if Alice and Wang Lung were activating the True Sword when they were coming out of the portal.

Well, Ren Di quickly threw the image of the corpses separating the two places out of his mind.

Seeing Ren Di's different face, Alice and Wang Lung obviously felt that Ren Di showed an inexplicable change. Alice paused for a moment and looked at Wang Lung with a smile on her face. Wang Lung frowned and looked at Ren Di, obviously thinking that Ren Di was thinking nonsense. Without communication, it is easy to misunderstand. Of course, Ren Di was also embarrassed, and said to the two: "When the two of you came out of the portal, I suddenly thought of a way to kill the two of you. "Perverted thoughts, just suppress them in the bottom of your heart.

The episode passed quickly, and Alice said, "In the underworld, we're in a bit of trouble. The computer quickly turned on, and the screen showed the underground world that had detected the northern world, and beneath the undulating surface, flat underground cavities in the rock formations were soaked in the rock formations.

Wells are drilled on the surface like tunnels drilled out of apples by worms that stretch into these underground spaces. And in the infrared pictures captured by unmanned detectors in these underground spaces, teams of special demons are active in these spaces.

Judging from the footage of the shots, it can be seen that all the demons are of the same species in terms of body size. Alice shifts the screen to a scene of demons of this race slaughtering all races in the underworld.

Wang Lung said: "This situation is distributed in forty-two underground spaces that have been detected, and it is very widely distributed. According to what is known, it cannot be ruled out that a force is emerging in the northern underworld. ”

Ren Di said: "I asked Yun Chenhe, the army on the surface of the Dawn Republic can deal with everything at the moment, but now the situation in the underground world must be contained. Ren Di looked at Alice.

Alice spread her hands and said, "This trouble has just thrown us like this?" Ren Di said: "It's not thrown on you, the army on the surface of this war will participate, and you who have fully underground operations should be prepared." ”

Alice said, "What preparation? Aren't any of us the main force in the war in the underworld? "We may use nuclear weapons in the underworld. The voice fell, and Alice said, "Not allowed." "It is very comfortable to use nuclear weapons to destroy a target. However, if the Republic of Dawn uses nuclear weapons underground, the nuclear radiation will not spread to the surface, but for the underground alliance that is about to occupy the underground, the underground environment is relatively closed, and the plutonium reaction is not complete, and it will not spread with the flow of the atmosphere, and a long nuclear radiation will be formed.

Alice then said with some anger: "All the current technological impetus in this world has been snatched by you, can't you use some means?" Wang Lung said leisurely: "At present, all our technology is driving the space program, and as for the operation in the underground world, we are now very lacking in weapon design. Alice, do you have any good advice? ”

Design, compared with the three major elements of industry, materials and processing, is often overlooked. But it is also extremely important. The performance of various materials is matched, and the precision control of various conduction of parts after processing is all need to be designed, and it is impossible for this world to have strong strength, good toughness, hardness, high temperature resistance, corrosion resistance, and all the advantages of the material, of course, through the combination of processing can not achieve the all-round effect. Therefore, it is a university to arrange the material parts with just the right performance to the right mechanical position.

Ren Di didn't believe in God, and the Knights were idle in the underground world. Although the standards of the Dawn Republic had to be used industrially, they definitely designed something using the standards of the Dawn Republic.

As soon as Ren Di asked, the fox's tail was quickly revealed. Alice felt that she was going to contribute the fruits of her labor to the Son of Heaven League again. Wang Lung appeared opposite Alice with a grin. Negotiations began.
