In the sixth year of elemental history, it has been two years since Longte arrived in this underground world. In two years, RF weapons appeared, instantly suppressing the human-sea tactics of the underground Gu nest forces. A large number of areas were re-controlled by the underground alliance. The first country in the underground world, unified administration, and escaped from chaos, has almost been established. Compared with the territory of the underground world forces that used to kill me and I kill you, this underground world is now considered to be the first time that it has been democratic and prosperous.

Well, the word independence cannot be embellished. The underground alliance now runs through all territories, all on the surface. This is more powerful than the Republic of China period when railway rights were regulated by foreign countries. Because of convenient transportation, underground forces in separate underground spaces have the foundation for a unified state. Any individual underground space has the act of disobeying the central government. The central government of the underground alliance can quickly mobilize armed forces to reach the area. The individual underground space has lost the possibility of becoming a prince.

However, this transportation line about the unification is on the surface. If it is drilled underground, the underground alliance wants to establish a large traffic, which can run through the entire underground world of the mainland. It is almost a century-old project. It is much easier to lay directly on the surface, but on the surface, it is equivalent to handing over the lifeline to the hands of the Dawn Republic. Behind the expansion and establishment of the underground alliance, there are a series of shadows of the Dawn Republic.

It provides resources several thousand meters underground on the entire continent, and these resources are mined by labor. Only by using industrial goods and commodity trade can we transport a steady stream of resources from the underground world to the surface. I am afraid that the superpower on the earth will not have such a huge colony.

The power of the underground alliance is the interests of the Dawn Republic. There are only interests between countries. The current underground world has not thought of independence and autonomy. Some cavemen in the underground alliance have not thought of getting rid of the control of the Dawn Republic in all aspects. The Dawn Republic also knows that there are such signs in the underground world, but the Dawn Republic has not strangled this "threat" to death and split the entire underground world regime. Why? Because the current underground alliance regime is very efficient and various economic and trade exchanges are very efficient. If a slag waste regime is replaced, it is impossible to successfully dispatch labor and maintain this efficient trade volume between the two sides, the Dawn Republic will suffer great losses.

Therefore, when dealing with other countries, sometimes it is not just about whether other countries are obedient or not. If they are disobedient, but the increase in trade volume can bring benefits, then at most it is to show off its force and fool the disobedient country (it is another matter if you can't fool it). The investment of this army is worth it compared to the stable trade volume of this country. If the benefits brought by this country are too low, no matter how obedient the regime is, it will not be favored.

Now the interests of the Underground Alliance to the Republic of Dawn have reached the point where the Republic of Dawn is allowed to fight for the Underground Alliance. For the Republic of Dawn, it will quickly eliminate all the security risks in the underground world, and then let the Underground Alliance safely remove the wartime system and send labor to the economy. Now it is no longer a problem of insufficient mining minerals, but a problem of insufficient labor in the underground world.

Now many underground alliances in unsafe areas have not released workers in order to save labor. With the two years of RF weapons invested in the underground world, the warriors of Gu Nest stopped harassing for a while, just when everyone thought that the Gu Nest forces were dying in a stagnation.

The intensity of the war increased again. The sharp gas shocked, as the white rainbow shot out from the light edge, hitting the Gu Nest Army on the rocks in the distance. However, what surprised the human commander was that the lethal power of RF weapons was no longer as powerful as before, and it was no longer a sweep of a large area. Only within 50 meters of RF weapons attacks could these demon warriors die.

Ronte said: "Everyone listens to my orders and shoot." Looking at the demons charging ahead, ten days ago, the intensity of war in the underground world increased, and the killing efficiency of RF weapons had been weakened. Three armies could not be tempered and lost heavy weapons of RF weapons. The human mecha legion had to retreat under the attack of tens of thousands of demon warriors.

The demon army appeared frequently in the past few days, until now it was encountered by the army led by Longte. At this time, the only RF weapon launcher in Longte's team climbed onto a rocky high ground with four legs, and launched the demon who charged at an elevation angle from a high point.

The high-powered microwave swept across the entire charge demon legion like a storm. Although it was not lethal enough, the RF weapons were still effective. When the microwave storm hit, all the demons closed their eyes one after another.

Ronte obviously saw this scene. The mecha arm suddenly waved down, and this clear action made the mecha soldiers at the commander's physical order in each position and quickly opened fire. Bullets of bullets aimed at the demon legion in the charge. The demons did not have time to find cover and were hit by the bullets and were quickly penetrated into a pile of minced meat.

The demon in the charge quickly looked for hidden things like a mouse meeting a human. Ronter's arm suddenly lifted up and all the mecha soldiers stopped shooting. The battlefield began to stagnate, and a huge dull sound rang out in the empty field.

Behind the rear was a sniper like a tank gun, using a sniper gun to carry out armor-piercing shooting on the ground. The 25-mm-caliber armor-piercing bomb hit the rocks, and a large amount of gravel splashed out a large ball of smoke as the warhead hit.

A large pit was directly knocked out on the ground. The pit obviously failed to block the kinetic energy of the bullet. The bullet penetrated the rock to block it, and it also shattered the demons behind the rock. The large number of rocks smashed by the warhead also obtained the kinetic energy of the bullet. This kinetic energy acted on the demon and turned into a mixture of rocks and flesh. Just like the broken corpses of insects mixed in dry sand.

The sniper directly welded a long-body cannon on the mecha, with a dark caliber, and shot at the demon soldiers behind the cover. Such shooting had no effect on the huge number of demons in the Gu Nest, and the deaths of the demons in the Gu Nest could not reduce the morale of the demons in the Gu Nest. The exact killing of this kind of shooting was to boost the morale of the one on his side. If there was no such shooting, the human mecha soldiers huddled in the tunnel would become panic while waiting.

Humans are such creatures. Sometimes doing something on their own will make themselves uncomfortable. When they suddenly realize that doing something that makes them uncomfortable will make their enemies even more uncomfortable, they will persist in this discomfort.

As each bullet of the long-body sniper bullet eliminates a demon's battle result, it appears as the bullet hits the ground and throws out the residual limbs in the smoke, the human soldiers hiding in the tunnel no longer panic in waiting in the surround. Because during the waiting time, the number of demons is decreasing, although the reduction is very large, but it is decreasing.

If there were no such snipers, the demons lurked in the tunnel, and the mecha soldiers who had been waiting for the commander to open fire for a long time would become more and more impetuous. Now this kind of waiting does not consume human morale.

When a large number of demons flocked to start a charge again, with the radio frequency weapons, all the charge demons briefly closed their eyes to protect their eyes from being cataracted by microwaves. At this time, the mecha soldiers launched fire-gathering shooting at the exposed demons.

The demon's new warriors formed a charge cluster and were curbed under Ront's excellent battlefield command. As the legions of the Dawn Republic and the Underworld Alliance arrived quickly, the demon's legion quickly fell into a disadvantage.

After the commander of the Third Mobile Legion, the army led by Bibit, arrived at the battlefield, the situation quickly began to reverse. The guerrilla troops composed of floating motorcycles swam around the air in the underground world and quickly rushed towards the rear of the demon army.

A bunch of bullets in the air of five meters, shooting behind the demons on their heads. The red bullets ejected from the rotary machine gun with the flames, just like a light rain scrubbing the ground. The floating motorcycles are like such a group of tilted death light rain and dark clouds, which maneuver quickly on the battlefield. This is a unique army of the underground legion. If it is replaced by the weight of humans, such floating motorcycles will definitely not be so maneuverable and flexible.

Floating motorcycles are the most suitable air force in the underground world, but human mechas are the strongest heavy firepower. The encirclement was quickly formed. This time, there were no radio frequency weapons. Three hundred mechas, with large-caliber cannons, and three-dimensional firepower composed of motorcycles in the air, sweeping the demons on the ground like brooms. If the machine gun in the air is rainstorm, the projectiles sprayed by the mechas on the ground are hail. Two-caliber ammunition hit the ground area, and a layer on the ground was directly cut. No creature can survive this crazy metal meat grinder.

Of course, such a firepower tilt will not last long. After cleaning up an area, the mecha and air firepower will stop advancing and replace the garrison troops with defensive firepower. Ten minutes later, this offensive force continued to clean up after reloading ammunition.

Under saturated firepower, everything will be destroyed. The firepower of hundreds of thousands of bullets on the earth in a short period of time can block the missile strike defense system. After completely biting the demon army, the two officers Bibit and Ronte formulated a combat plan for cleaning one area by area. It is very effective and can be a complete annihilation battle.

Unlike human-shaped mechas, Bibit drives a slender four-legged mecha, and the cockpit of the mecha is protected by bulletproof glass. Sitting in the mecha, watching the gradually calming battlefield, Bibit, who is already a colonel, said to Ronte: "Major, I find that we have a happy cooperation. In the future, you act as bait and I cast a net, how about it?"
