In the 63rd year of the Elemental Calendar, it has been two years since Lunt arrived in this underground world, and two years of RF weapons appeared, instantly suppressing the crowd tactics of the underground Gu Nest forces, and a large number of areas were regained by the underground alliance. The first unified, unified administration, and chaotic order state in the underground world has almost been established. Compared with the underground world power territory in the past, where you killed me and I killed you at every turn, this underground world is now the first time that democracy has prospered.

Well, the word independence can't be whitewashed, the Underground Alliance now runs through the lines of communication in all territories, all on the surface. This is even more powerful than the Republic of China period, when railway rights were controlled by foreign countries. Because of the convenient transportation, the underground forces of a single underground space have a basis for great unification, and any single underground space has disobedience to the central government. The central government of the underground alliance can quickly mobilize armed forces to reach the area, and the underground space alone has lost the possibility of being a prince

However, this communication line related to the great unification is on the surface, and if it is drilled underground, the underground alliance wants to establish a communication line that can run through the underground world of the entire continent with a large flow rate, which is almost a century-old project. It's much easier to lay directly on the surface, but on the surface, it's equivalent to putting the lifeblood in the hands of the Dawn Republic. The expansion and establishment of the underground alliance has a series of shadows of the Dawn Republic behind it.

Provide the resources of the entire continent thousands of meters underground, and these resources are mined by labor, and only need to trade industrial commodities to transport a steady stream of resources from the underground world to the surface, I am afraid that the superpower on the earth does not have such a huge colony.

Where the power of the Underground Alliance lies, the interests of the Dawn Republic lie. There are only interests between countries, and the current underground world has not thought of independence, and some of the troglodyte leaders of the underground alliance have not thought about getting rid of the control of all aspects of the Dawn Republic. The Dawn Republic also knew that there were such signs in the underground world, but the Dawn Republic did not strangle this "threat" in the signs and split the entire underground world regime. Why, because the current underground alliance regime is very efficient, and all kinds of economic and trade exchanges are very efficient, if it is replaced by a scum and waste regime, it cannot successfully mobilize labor and maintain this efficient trade volume between the two sides, and the Dawn Republic will lose a lot.

So when a big country deals with other countries, sometimes it's not just about seeing if other countries are obedient or not, if they don't listen, but if the volume of trade can bring benefits, it is at most a show of force to frighten the disobedient country (bluffing or not that's another matter). This investment in the army is worth it compared to the country's steady volume of trade. If the benefits of this country are too low, the regime will not be treated well no matter how obedient it is.

Now the benefits of the Underground Alliance to the Dawn Republic have reached the point where the Dawn Republic is fighting for the Underground Alliance. For the Republic of Dawn, quickly eliminate all the security risks of the underground world, and then let the underground alliance dismantle the wartime system with peace of mind and send labor to the economy. It is no longer a problem of insufficient minerals to be mined, but a shortage of labor in the underground world.

At present, many underground alliances in unsafe areas do not put workers in order to save labor. With the RF weapon being deployed in the underground world for two years, the Gu Nest's soldiers stopped harassing for a while, just when everyone thought that the Gu Nest forces were dying out in their last breath.

The intensity of the war has risen again. "Whoosh" The sharp gas shock, as the white rainbow shot out from the edge of light, hit the Gu Nest army on the distant rock, but to the great surprise of the human commander, the lethal power of the RF weapon was not as strong as before, it was no longer a large area, only within fifty meters of the RF weapon's strike, these demon soldiers died

"Everyone, follow my orders, shoot." "Looking at the demons charging ahead, ten days ago, the intensity of the war in the underground world had increased, and the lethality of radio frequency weapons had weakened, and three armies were caught off guard and lost radio frequency weapons and heavy weapons. The human mecha legion had to retreat under the attack of tens of thousands of demon soldiers.

In the following days, this demon army appeared frequently, until now it was encountered by the army led by Longt, at this time, the only radio frequency weapon launcher in Longt's team, climbed up a rocky high ground on all fours, and condescendingly fired at the demons charging at the elevation angle.

The high-power microwave swept through the entire charging demon army like a storm, although the lethality was insufficient, but the radio frequency weapon was still effective, and when the microwave storm hit, all the demons closed their eyes one after another.

It was clear that Lunt saw this. The mecha arm waved down suddenly, and this clear action made the mecha soldiers in each position see the commander's physical order, and quickly opened fire. Bundles of bullets were aimed at the charging demon legions, and one by one the demons were hit by the bullets before they could find cover, and they were quickly pierced into a pile of minced meat.

The demons in the charge quickly looked for shelter in the potholes like rats meet people, and Lund's arm suddenly raised, and all the mechs stopped shooting. The battlefield began to stagnate, and a loud muffled sound sounded in the open space of the battlefield.

In the rear, a sniper like a tank gun was held to carry out armor-piercing fire on the ground with a sniper gun, and the armor-piercing shell of 25 mm caliber hit the rock, and a large amount of rubble was splashed out with the impact of the warhead.

A large crater was directly punched on the ground, and the crater obviously failed to block the kinetic energy of the bullet, and the bullet penetrated the rock barrier, and even smashed the demon behind the rock, and a large number of rocks that were smashed by the warhead also got the kinetic energy of the bullet, and these kinetic energy acted on the demon, directly turning into a mixture of rock and flesh. Like the remnants of bugs mixed in dry sand.

The sniper, who welded a long-barreled cannon directly on the mecha, with a swarthy caliber, shot at the demon soldiers behind the bunker. Such a shot would have no effect on the huge number of Gu Hive Demons, and the death of Gu Hive Demons one by one would not lower the morale of Gu Hive Demons. To be precise, the killing of this kind of shooting is to boost the morale of their own side, and if there is no such shooting damage, the human mecha soldiers who are huddled in the tunnel will become panicked in such a wait.

Humans are such creatures that sometimes doing something on their own makes them uncomfortable. When you suddenly find that doing this thing that makes you uncomfortable will make your enemies more uncomfortable, you will persist in this discomfort.

With the long-barreled sniper bullet destroying a demon with each bullet, and the result of the bullet landing on the stump and throwing it out in the smoke, the human soldiers hiding in the pit no longer have the panic of waiting in the encirclement. Because the number of demons decreases during the waiting time, although this reduction is very small. But it's decreasing.

Without these snipers, demons lurk in the tunnels, and mech soldiers who have been waiting for the commander's order to fire for a long time will become more and more impetuous. Now this wait has not consumed human morale.

When a large number of demons swarmed up again and launched a charge, along with the RF weapon, let all the charging demons close their eyes for a short time to protect their eyes from being turned into cataracts by microwaves. At this time, the mecha soldiers launched a concentrated fire shot at the exposed demons.

The demons' new warriors formed a charging group, which was contained under Longt's excellent battlefield command. With the rapid arrival of the legions of the Dawn Republic and the Underground Alliance, this demon legion soon fell into a disadvantage.

After the commander of the 3rd Mobile Legion, the army led by Bibit arrived at the battlefield, the situation quickly began to reverse, and the guerrilla force composed of airmobile vehicles quickly rushed towards the rear of the demon legion after swimming in the air of the underground world.

Beams of bullets in mid-air at five meters above the head shoot at the back of the demon. Crimson bullets erupted from the minigun with flames, like a rain of light washing the floor. Floating motorcycles are such a group of oblique death light rain clouds, fast maneuvering on the battlefield, this is the unique class of troops of the underground legion, replaced by the weight of human physique, such floating motorcycles can never be so mobile and flexible.

Airbikes are the most suitable air power in the underworld, but human mechs are the most powerful heavy firepower. The encirclement was quickly formed, this time without the use of radio frequency weapons, three hundred mechas, flat-ended large-caliber machine guns, and three-dimensional firepower composed of motorcycles in mid-air, like a broom, to clean up the demons on the ground, if the machine guns in mid-air were said to be torrential rain, the projectiles sprayed by the mecha on the ground were hail, two caliber ammunition, hit the ground area, and the upper layer of the ground was directly cut. No creature can survive this crazy metal meat grinder.

Of course, this kind of fire tilt did not last long, after clearing an area, the mecha and air fire began to stop advancing, replaced by the garrison to arrange defensive fire, ten minutes later, this attacking force, after reloading the ammunition, continued to sweep.

Under saturated firepower, everything will be destroyed, and the firepower of hundreds of thousands of bullets fired in a short period of time on the earth is a defense system that can block missile strikes. After completely biting the Demon Legion, the two officers, Bibit and Ronth, formulated this battle plan for clearing each area. Very effective, so to speak, a complete war of annihilation.

Unlike a humanoid mech, Bibit pilots a slender quadruped mech with a bulletproof glass cockpit. Sitting in the mecha and watching the battlefield gradually calm down, Bibit, who was already a colonel, said to Longt: "Major, I found that we have a very pleasant cooperation, in the future, you will be the bait, and I will cast the net, how about it?" ”

The ranks of the Underground Alliance, which are also recognized by the Republic of Dawn, are both sides facing a common enemy at the same time, so an integrated command system is formed. Under this integrated system, officers on both sides are expected to respect the ranks of both sides. So in the face of cavemen with higher ranks than himself joking with himself, Lunt had a wry smile on his face. said: "Mr. Colonel, then you must cast the net quickly, otherwise I may not be able to use it as bait a few times." ”
