The entire crust of this giant planet is composed of hard ores, which is a super resource-rich planet, and after the long-term operation of the federal army, a large number of military bases and automated industrial centers have been built, and there is a huge base of surface mechanized defense corps.

It's just that this is a huge planet, and the vast surface area makes the Federation planetary defense system still have some relatively weak areas, and these weak areas, under normal circumstances, are not a big problem because of the existence of the orbital defense fleet.

However, this super-large-scale raid by the Biochemical Legion, the space fleet that took advantage of the order of magnitude advantage dragged down the orbital defense fleet, which made the defensive disadvantage of these gap areas be expanded, and became a breakthrough for planetary landing.

Every second, thousands of Biochemical Corps landing ships jump directly from the parent fleet into near-Earth orbit at a near-Earth warp and then drop ground troops.

It's just that the implementation rate of this short-range warp speed method is extremely high, and it is easy to directly cause damage to the ship's hull due to collision with some macroscopic materials, but the Biochemical Corps obviously doesn't care about it, and wants to break into this star at any cost.

"Captain! Massive in-transit reinforcements have arrived! Whether to push forward again! ”

The Demon Thorn Warframe inserts its short sword through the armor into the head of a biochemical war beast, slashing the head of the beast with a single sword, leaving the slow-moving behemoth to friendly fire.

At the same time, because of the arrival of another batch of ground reinforcements, the captain was asked if he would advance further.

"Push! Battlefield Message! The space fleet that has been reinforced with us has helped the space battlefield to recover its disadvantage! The next reinforcement fleet is expected to arrive in 4 hours! Hang on! We'll have a fleet to support us! ”

The neat armor defense line obeyed the command system's instructions and advanced neatly again with a predetermined course of action, once again curbing the offensive momentum of the biochemical beast tide.

Each armor dances in the long-range firepower of both sides, and needs to give up the strike space of the rear firepower and the enemy's firepower according to the synchronous action data at the same time, because the firepower of the two sides on the current battlefield is too dense, illuminating the entire dark night sky.

The mines on the giant planet that are in the rear of the defense, the automatic factory is at full power, producing all kinds of material supplies on the front line, and continuously transporting them to the front line through high-speed air transport units, thanks to the surface road network that runs through the entire star, some limited ground mechanized force resources are unified through the deployment of the battlefield command system to those important battlefields where the battle is fierce.

However, this area support is also limited, because the Federation army has to defend the entire planet, and the basic defense force of each area must be kept at a standard line, and at the same time, the defense strength of each defense area is also limited.

Therefore, the Biochemical Legion is able to make a number of surprise attacks in points, breaking through the upper limit of defensive ability in a certain area and breaking through to the surface.

What the federal ground forces are doing now is to say that these landed biochemical legions are locked up in a certain area to prevent their spread.

However, it is not possible to concentrate the forces of all defense zones, because the Biochemical Legion can shift the center of gravity to break through at any time and look for loopholes in the Federation's surface defense system, because in the previous raids, the Biochemical Legion can bring great trouble to this long-established strategic planet of the Federation.

The Federation's in-transit support fleet continues to arrive in this system, quickly entering the battlefield to fight, and the main force of the warframe troops carried by it is quickly dropped on the surface of these planets to join the ground defense operations.

It's just that for a huge planet, even if it is the hundreds of thousands of battle armor troops brought by the three waves of fleets, it is just a small wave in the sea, and the order of magnitude of the federal combat units in this battle has exceeded 100 million, and the order of magnitude of the combat units invested by the biochemical legion has been as high as billions according to the calculation of the battlefield command AI, and the troops of both sides are engaged in a tragic battle in this star system from space to the surface of the planet.

On the battlefield where the E3 Apostle Squad is located, thousands of air units on both sides are taken advantage of every moment, and then the wreckage falls to the surface, causing a wave of powerful explosions again, like a meteor shower.

The battleframe units on the battlefield here faced the enemy's elite biochemical beasts, and after 17 minutes of fighting, as the battle line advanced, the intensity of the engagement quickly escalated, and the first battle-damaged unit appeared, which was obvious

"Focus! The A4 squad has been damaged! Watch out for enemy stealth units! ”

"Impatiens fire! Start a battlefield scan! ”

"Yes!"

Just now, the assault of the A4 squad, a berserk mecha lost its balance and fell to the ground because of the surprise attack of the enemy's stealth unit, and was directly broken through the defense by the fire strike of the place that followed, and then it was besieged by a large number of biochemical war beasts, and he could only choose to self-detonate and sacrifice.

The battlefield command system quickly merged the A4 squad into the surrounding squads, otherwise the Warframe squad without the assault will have a lot more pressure on the melee defense.

With this example in the past, the old brother was not cautious, and quickly ordered the Phoenix Immortal Fire to conduct a large-scale battlefield exploration.

I saw that the wings of the Phoenix Fire Battle Armor were spread to the extreme, and 512 sets of laser beam generators shot out from the wings, encompassing the surrounding combat area.

With a twist, the Warframe Detection System quickly marked those obviously abnormal irradiation areas, and a total of 14 biochemical beasts with stealth abilities had already approached the 50-meter area of the team!

"Twin knives!"

"Understood!"

The specially modified cutting chains of the Demon Thorn Warframe shot out, confined the two invisible cyborg beasts in place and locked them firmly.

At the same time, the short sword in his hand, the shoulder particle cannon and the superlight cannon that had been stored for a long time were multi-pronged, causing damage to seven biochemical war beasts in this short instant.

With the tacit attack of their teammates, the 14 invisible biochemical beasts lost their combat ability the moment they were discovered, and then slashed.

Especially the two that were hit by the Phoenix Fire Sniper Cannon and the kinetic energy blasting axe thrown by Black King Kong were directly smashed by half of their bodies, bursting out a cloud of flesh and bone scum.

"Beware of evasion! The enemy is on fire! ”

A warframe unit with such a powerful melee ability is simply an impassable wall at the front of the battle line, which rigidly restricts the biochemical beast group's intention to break through.

This is where the melee capability of the ground combat system is necessary, and it is also the accuracy of the battlefield positioning of the battleframe troops.

These thick-skinned biochemical beasts are indeed not strong in their defense against long-range firepower, but due to the existence of self-healing ability, they have a strong ability to resist small-caliber penetrating wounds, and they need high-explosive strikes or fierce firepower strikes to completely lose their ability to act.

Warframe units, on the other hand, can effectively lose their mobility by simply cutting off their main heads, which are used to collect information about the outside world, or severing their mobile limbs with several slashes, which is more efficient than long-range strikes, and saves energy and ammunition.

E12 is now cutting a huge wound in his left and right hands for several years, and then get out of the way, dodging the counterattack of this biochemical war beast, and at the same time, let the antimatter grenade thrown by the captain accurately enter the depths of the beast's body through the wound, and then bend down and flee directly, leaving only endless light and heat to completely destroy this huge biochemical beast's body.

"Combat network markers are synced! Be careful to circumvent! ”

The combat signal of the team is refreshed at a very high speed, but in the long-term training, the E12 has formed an instinctive reaction, which is that the Phoenix Fire wants to release its own guided missiles for fire coverage strikes to support itself at the front of the battle line and is about to be encircled.

The ghost thorn armor tricked into the abdomen of a cyborg beast with the speed of ghostly maneuvering, and with a return attack, it accurately cut off the nerve transmission network in the neck, leaving the short sword there directly, and then took out a spare short sword, and the double swords flew, directly cutting off the three pairs of walking limbs of the biochemical beast, hiding under its huge body.

"Boom!"

"Boom, boom!"

At the same time that the Ghost Thorn Battle Armor completed these series of operations, the Fire Covering Strike of the Phoenix Immortal Fire had already arrived nearby, and a strong chain of explosions enveloped the entire area, and those surrounding biochemical beasts were shattered by the explosion, and they quickly attrition.

5 seconds later. The ghost thorn crawled out from under the charred corpse of the cyborg, and in front of him was a large crater on the ground that had crystallized from the bombing heat.

At this time, the temperature reading has reached a terrifying 513K, and there are a large number of toxic substances filling the environment, which is definitely far beyond the defense limit of different individual protective armors.

"Whew, this burnt smell of barbecue is much worse than when I was training."

The Ghost Thorn Armor used the short sword in his hand to scrape off some of the charred flesh adhered to the elbow joints, and because of the high temperature, the air flow formed by the large amount of gas expelled by the heat dissipation system of the fuselage swept across the surrounding surface, stirring up a lot of dust again.

The head of the armor was slightly deflected, and the trajectory of a heavy particle sniper cannon hit a cyborg beast behind it with a slight glove of the head of the ghost thorn, and at the same time, a pitch-black round alloy shield flew through the smoke and dust from the direction of the team with a whistling sound, blocking a dark blue claw that emerged from the sky for the ghost thorn armor, and was firmly grasped by the ghost thorn, and a backhand slash chopped the entire claw off.

The moment E12 saw the overall appearance of this claw, he had already simulated the posture of this biochemical beast in his mind synchronously with the warframe host, which was obtained from long-term training, and then a shield hit blocked the air, which was its second attack claw, and then directly lowered his head, dodging the three consecutive attacks of the tail spur of this scorpion-level biochemical beast that was still invisible, and the two particle shoulder cannons were sent directly to the opponent.

"Sample, have you learned well, and you know how to use your teammates' corpses to avoid bombing?"

The piercing wound caused by the two shoulder cannons attacked the main control organ of the scorpion-level invisible shell, making the scorpion fully manifest, and at the same time cleanly and neatly occupying its other claw again, the whole process was just 3 seconds.

Then it is natural to retreat at a high speed, most of these invisible beasts have the ability to self-detonate with one hand, E12 knows this very well, and at the same time, 3 seconds is also the reloading time of the Phoenix Fire Heavy Particle Sniper.

"Goodbye, little scorpion!"

The retreating Demon Thorn easily drew the short sword that had been inserted in the neck of the dodging corpse, and watched as a sniper light cannon from behind the smoke and dust accurately hit the scorpion-level self-detonation core, completely destroying it.

"Scalpel! It's really accurate! ”

The Ghost Thorn salute was still coming, and at the same time as detecting a long-range ballistic strike, he threw the black shield in his hand, deflecting the trajectory of this attack for the Phoenix Fire Battle Armor, and then quickly retreated into the squad formation.

"Where, where, it's still your double sword chains playing with it!"

"Kill?"

"Keep killing!"
