Tyranid.

They are the most feared predators in the universe, and their purpose seems to be to prey and digest, not only tearing enemies apart with their claws, but also shooting them from a distance with their biological firearms.

A vanguard of countless Zerg soldiers and obscuring creature warships, designed to destroy all resistance.

Driven by endless hunger, these predators are destined to rob other lives of their survival resources.

Witnessing an invasion of Tyranid creatures is the equivalent of observing a devastating process, with thousands of sporangia dripping like raindrops, hitting the ground or bursting open after being attacked.

It was like a flower of death that represented destruction, and hordes of Tyranid creatures gushed out of these sporangia and coalesced into a great torrent.

Within days of the first Tyranid spores entering the planet's atmosphere, the surface of the target planet should be filled with boiling xenomorphs.

】

Although the anti-aircraft artillery fire on the Long River Star has slowed down this process a lot, under the continuous dropping of Tyran's airdrop bags, except for the human cities and fortresses, all of the Long River Star has been reduced to Tyran's territory.

Fortunately, before the arrival of the Tyranid Zerg, the people of the empire went to the city for refuge under the organization of the planetary government.

In a fortress on the outskirts of a city on the planet of Long River.

Commander Miles climbed the ladder and then stood on the protective wall. Behind him was a group of high-ranking officers who had just been urgently summoned by him.

He scanned his surroundings and saw a soldier in power armor standing at his own post, vigilantly guarding against a possible attack by the Tyranid creatures.

The muzzles of the fixed turrets and heavy weapons were aimed above and far away, guarding against the charge of the swarms and the invasion from the sky.

But Commander Miles was not happy with this.

"How's the perimeter line going?" Miles wanted to hear better from his lieutenant.

"The situation is unknown, but the front-line commander has requested support from the Panzer Group and the Space Marines from General Wadez."

"Hopefully they'll hold on."

Miles said as he brain-manipulated the tactical display built into the helmet. The tactical display inside the helmets of the officers behind them has changed, revealing the current network of trenches and the placement of weapons on the ground around the fortress.

"Now that we know that the aliens have diggers, the enemy can use this three-dimensional advantage to attack anywhere, which makes our underground defenses look vulnerable, and the fortifications on the surface are far from enough."

"So we need to be prepared for a surprise attack by bugs digging tunnels."

"Bhullar, double the number of soldiers on duty at the protective wall."

"Company Commander Mendes, lead your troops to find out what is going on in the underground space."

Commander Miles turned to his lieutenant and an officer.

"Yes, sir."

Miles' gaze scanned the crowd and said solemnly.

"Although the line of defense that has been attacked is far away from us, we must not take it lightly. This could be a precursor to an all-out attack by the biters! ”

"From now on, unless you die, everyone must keep their guns in their hands and their armor in their bodies! Always ready for battle! ”

"Yes!"

Watching the officers descend from the protective wall, Miles turned and fixed his gaze on the messy ground in the distance of the fortress.

The plains, once covered in dust kicked up by artillery fire, were now covered in wildly grown alien leaf-like creatures and tall chimney-like organisms. With a disgusting twitch, the "chimneys" spewed clouds of smoky and highly toxic spore into the scorching sky.

A few days earlier, those plants and countless Tyranid creatures had been bombarded by Imperial artillery, leaving only a crater on the ground. But those anomalous vegetation regenerates at a rate no less than destroying them.

He had sent soldiers to burn it and tried to clear several areas in front of the protective wall, but to no avail.

Suddenly, Miles felt what seemed to shake under his feet, and then heard a shout coming from the far side of the protective wall.

"They're coming! Attack of the Tyranid Zerg!"

Miles looked up at the sky, and the irregularly shaped black cloud was rapidly approaching against the wind, it was the aerial swarm of the Tyranid Zerg.

In a dense forest in front of the fortress, tall grass shook wildly as unknown creatures moved in between.

In the distance, the swarm was running towards them on the ground, their bony jaws full of fangs and a shrill roar.

Small bugs with sickle claws and thick carapace form a strange horizontal and vertical formation, screaming and jumping over obstacles in their path.

"Prepare for battle!" Miles shouted, then pulled out his plasma pistol and contacted the officer who had just left in the communication channel.

"Command your soldiers, all of them go up the walls and get ready for battle!"

Over the years, the Zerg have attacked the fortress several times, but each time they have been repelled by the Empire's powerful firepower. Whenever the Tyranid creatures appeared, the Empire's artillery was already on their way.

In the past, no Tyranid creature had even touched the walls of the fortress.

But this time was different, feeling the tremors under his feet, Miles knew that this was the precursor to an attack by the Tyron Diggers, who had just broken into one of the Empire's defenses.

The two attacks were launched in such a short time that they were barely given time to react.

What Miles didn't know was that at this time, the other lines of defense in the city, as well as the other cities of the Long River Star, were almost simultaneously invaded by Tyran.

This is a big general attack for Tyranid creatures.

It is not an instinctive beast as the Imperial scholars imagine, but on the contrary, it is intelligent enough to make the races that have succeeded in establishing civilization in the galaxy feel inferior.

From the very first day of its attack on the Long River, it learns the Empire's tactics and tactics from the attacks of the Empire's forces and researches ways to counter them. Although it cost a lot of casualties to the Tyranid creatures, these are nothing to the Tyranid Zerg.

Attacks beneath the surface were effective in protecting against the Empire's powerful artillery, and the Tyranid creatures that poured out of the ground took little damage except for a layer of dust covering them.

At the foot of the fortress's walls, a group of Tyranid creatures broke through the ground and then used their sharp claws to grasp the outer walls of the walls and climb upwards.

"Aim at your target and fire freely!"

Miles shouted, though he knew that firing at such a large swarm of bugs didn't need to be aimed at at all, because it was impossible to miss.

He raised his plasma pistol and kept shooting at the gathered swarm.

The sound of explosive shells and lasers from the soldiers, the roar of anti-aircraft guns in the fortress and on the protective walls as they fire at the gargoyles in the sky, the sound of sentry and automatic artillery attacks, the roar of heavy artillery from behind.

Coupled with the inhuman shrill screams of the swarm, the previously silent environment was instantly filled with the noise of pre-death.

High-powered laser rays rained down from the wall, each laser piercing the body of an alien monster, but Miles knew that the attacks were far from enough to stop them.

Even if every soldier was able to hit and kill a bug with every shot, there would still be thousands of remaining bugs to clean them up.

There were too many swarms of biters pouring out of the fortress through the underground passages.

"Fuck, can't these bugs hollow out the ground! So how big the hell is that underground passage!? ”

Miles kept firing and venting his anger.

There is no need to worry about the plasma pistol overheating and exploding, as this is a new model developed by the Empire, which is equipped with advanced cooling modules and heat dissipation systems.

Eliminated many of the shortcomings of Imperial plasma weapons, virtually eliminated the need for recharging, and significantly reduced the excess heat generated by conventional plasma weapons.

More power, more fires.

But how many Tyranid creatures can Miles' pistol stop alone?

The muzzle of his gun was steaming, and the ammunition indicator flashed red rapidly. Under Miles' frenzied fire, the plasma pistol was no longer able to deliver lethal attacks after killing an unknown number of Tyranid creatures.

Even in the midst of the deafening noise, Miles could hear the bugs clawing against the wall as they climbed the guard.

A stream of bright green slime hit the protective wall next to him and splattered in all directions. The slime-stained soldier's power armor sizzled, and the strong acid corroded the outer armor of the power armor, leaking out the wiring inside.

If there were no power armor, I am afraid that this strong acid would have melted the flesh and blood of the soldier long ago, revealing Bai Sensen's bones.

Just then, the first bug climbed the protective wall of the fortress.

It had the head of a typical Tyranid bug, its bloody mouth wide open, and its piercing screams. The mouth is covered with layers, jagged razor-like fangs.

But before it could move, a laser from behind Miles pierced through its body. Just as the Tyranids were about to ascend the protective wall, reinforcements from the fortress also rushed to the protective wall.

Adjutant Bhullar walked over and stood beside Miles, holding the laser gun in his hand and firing several more shots at the Tyranid creature.

According to an anatomical analysis of dozens of Tyranid creatures by Imperial biologists, these Tyrannics usually have no obvious liver, kidneys, digestive tracts, or other glands.

This allows Tylen Bio to tap into valuable biological space to accommodate additional defenses, muscles, and redundant systems.

Unless the central nervous system is severely damaged, it is difficult to kill a Tyranid creature without causing significant damage to multiple systems.

Anyone wishing to kill Tyranid creatures with ranged weapons should consider this information.

The part covered by the carapace should not be targeted, with the exception of anti-tank weapons. Eyes, neck, and joints are the weaknesses of almost all Tyranid creatures. However, injuries to a limb are unlikely to be fatal except in extreme cases.

So, just in case, Bhullar shot the Tyranid a few more times to make sure it was dead.

Miles couldn't help but breathe a sigh of relief when he saw Bhullar leading a large number of reinforcements, but he immediately ordered.

"Bhullar, quickly lead the soldiers to arm themselves on the protective wall."

"We should be able to block them."

Bhullar grabbed Miles, who was about to command the battle.

"They've broken through." Bhullar said.

"Large and small digging insects, as well as an unknown number of soldier insects, followed along the tunnels dug by the big guys." He turned, keeping an eye on his surroundings to prevent the Tyranid creatures from sneaking up.

After hearing Bhullar's words, Miles instantly thought of a terrifying possibility.

"They're attacking artillery positions?"

"That's right. I've got a force rushing to the back. Bhullar nodded, and said in an eager tone. But you'll have to get back to the operations command room right away. ”

"Damn, you're in charge of directing the battle here."

Hearing Bhullar's answer, Miles didn't care about anything and immediately ran towards the command room in the fortress.

These Tyranid creatures that are close to the fortress walls cannot be attacked by the Empire's artillery units because they are too close.

But the dense swarms of gargoyles in the sky, and the swarms of insects rushing towards the fortress like an ocean in the distance, all relied on these powerful cannons to stop them.

If the artillery unit is destroyed, it will be almost impossible for the soldiers in the fortress alone to stop the charge of the second wave of Tyranid creatures when they arrive.

Miles drove a motorcycle to the tactical command room at top speed, contacting his officers.

"Mendez, scan and scout in the fortress, I want to know how many Tyranid creatures are in the fortress!"

"Archer, Dasha, lead the soldiers to the generator room and reactor hall to defend the Void Shield!"

"The rest, go to support the artillery units!"

"Yes, sir!"

While giving the order, Miles succinctly reported the situation of the fortress to his superiors, hoping to get support.

......

......

The sky was dark, I don't know if it was because of the obscuration of the Tyranid creature ships, or because of the pollution caused by the explosion of the Empire's many shells.

And in this dark sky, a team of Thunderhawks carried deadly passengers and quickly moved forward.

Their speed is astonishing, reaching several times the speed of sound. After receiving the order, it only took a few minutes to transport the Space Marines to the designated location.

The soldiers here still put up a stubborn resistance, and the anti-aircraft artillery attacked the gargoyle hordes in the sky.

Thunderhawk maneuvered in order to avoid the trajectory of the shells. The plane swayed in the munition-disturbed air, and they made their way to the top of the battlefield.

The ground is filled with countless Tyranid creatures, and the soldiers leave bunker to protect their defenses and confront these terrifying aliens.

And just as Thunderhawk was looking for a place to land, the Tyranid Zerg in the sky spotted them and took them as prey.

"Mind you, the aerial swarm is approaching. Begin to evade maneuvers. ”
