"Fire!"

With the Commander's roar, the weapons in the defensive array launched an attack on the Tyranid swarm that was charging towards them.

At the rear of the position, on the artillery position, which was firmly protected by the soldiers, the erected barrels were like big trees made of steel, forming a forest of steel.

A series of heavy artillery, such as earth-shaking cannons, heavy mortars, giant artillery, and siege artillery, fired high-explosive and incendiary bombs that poured down on the faces of the Tyranid swarm like a torrential downpour.

Cannons are like forests, bullets are like rain.

The dense charging formation of the Tyranid swarm maximizes the attack power of the Imperial cannonballs. A single cannonball would kill hundreds of Tyranid creatures.

However, the Tyranids quickly relied on their sheer numbers to reach the outermost line of defense of the city. The sheer number of these Tyranid creatures was so large that even the Empire's extremely intense bombardment couldn't completely stop them all.

】

However, heavy artillery attacks were only the first line of attack in the Empire's bombing tactics.

The Tyranid creatures that rushed to the outermost line of defense had just seen the Imperial soldiers, and a large number of defensive weapons such as sentry cannons, cresmatic towers, and magnetic storm coils, which had a slightly closer attack range than the cannons, began to attack the Tyranid creatures whose number had been greatly reduced.

The twin large-caliber multi-barrel rotating blaster barrels on the Sentinel Cannon fire Vulcan Megablasters at a rate of hundreds of rounds per second.

This Vulcan Megablaster is usually mounted on super-heavy tanks, Titans, and sometimes starships as point defensive weapons.

Any Tyranid that rushes into its range will be torn to shreds by a stormy attack.

Although this weapon has a high degree of inaccuracy, the high accuracy often seems somewhat insignificant for a weapon that can create hundreds of square meters of explosive death rain.

And the high-energy lasers emitted by the prism tower, and the powerful arcs emitted by the magnetic storm coil can directly turn those Tyranid creatures into ashes.

By the time the swarm rushed in front of the astral army, 99.9 percent of the Tyranid creatures had fallen in their path.

The rest were easily killed by the Astral Army using the laser guns in their hands.

Once again, the Astral Army crushed the Tyranid creature's charge.

In the command room in the rear, Wadez looked at the war situation displayed on the hologram and listened to the reports of the soldiers around him, and a feeling of unease arose in his heart.

Although he once again repelled Tyron's attack, it was too simple.

Wadez put together information from several Tyron attacks.

It's been a long time since the first Tyranid creatures attacked, and Tyranid has launched several attacks on the city in the interim. But there has never been a real threat to the city.

Why would Taryn still carry out such an ineffective method?

Wadez looked at the information on the tactical display with some confusion.

Intelligence, the large creatures in the Tyranid swarm were gradually decreasing in number over several attacks. This time, almost all of the Tyranid attacks were low-level Tyranid creatures such as knife worms and spear worms.

Wadez picked up a glass of water beside him, drinking as he pondered Tyron's tactical intentions.

Although the Empire has annihilated a large number of giant Tyranid creatures in several attacks, the Tyranid Zerg are far from breaking their bones.

So far, the behavior of those hive fleets in the sky dropping spores into the Long River Star has not stopped, could it be that they are all filled with such low-level bugs?

Perhaps, the Tyranid want to rely on these basic Tyranid creatures that can multiply in large numbers to deplete the ammunition reserves of the Long River Star through the tactics of numbers and swarming.

Wadez stood up and paced around the room.

He vaguely felt that this was not the final answer, and began to wonder if he had missed something.

But in the end, Wadez couldn't think of any other reason for the Tyranid to carry out such a senseless act of sending them to death.

Among the current scholars of the Empire, the prevailing view of the Tyranids is that they are a pack of beasts driven by hunger desires.

But even a beast that lacks reason, under several head-on blows, should know how to change.

Wadez sat down again, holding the glass back in his hand.

Leave the giant, elite high-level Tyranid creatures behind for now, and let the massive, easy-to-produce low-level Tyranid creatures consume the Empire's ammo.

When the Empire's artillery can no longer spit out tongues of fire, that's when the Tyranids launch their fiercest attacks.

This is the tactical means of the Zerg that Waldez is currently guessing.

But... Hehe.

A smile leaked from Wadez's face, and he picked up his glass to drink it all. But when he raised his head, he found that the cup was empty.

Thirsty, Wadez looked out around the command room, but there was no water source.

It's no wonder, after all, the command room is not a kitchen.

"Grosso."

Wadez called in the guards who were on guard outside the command room.

"General, what are your instructions?"

Hearing Wadez's shout, Grosso immediately pushed the door in, walked to Wadez's side, gave him an Aquila salute, and respectfully awaited the general's order.

"I'm sorry to get a glass of water for me."

Handing the glass of water in his hand to Grosso, Wadez felt a dry feeling in his mouth, swallowed and said.

"It's my pleasure to serve you, General."

Grosso didn't show any dissatisfaction, took the glass of water from Wadez with both hands, and immediately turned around and walked out of the room.

And when Grosso reached the door, he stopped, turned to Wadez and asked.

"General, do you want hot water or cold..."

In Grosso's sight, Wadez clutched his throat in pain and fell to his knees with a hideous face.

"General!"

Throwing the glass of water away, Grosso quickly ran towards Wadez.

"Bang"

The glass of water fell to the floor along with Wadez.

......

......

Drain the enemy's ammo reserves with a large number of low-level biters, a common tactic for the Zerg.

The knife insects and gun bugs in the Tyranid Zerg were originally produced as cannon fodder. Lacking a digestive system, even if they are not killed by the enemy, they basically do not live long after birth.

If you can get the enemy to pay more ammo for their lives, their mission is complete.

However, if you want to deplete the ammunition reserves of the Imperial forces on the Long River Star, it is somewhat unlikely to rely on the Tyranid creatures in the White Hart System alone.

At present, since the first Tyranid biological ship arrived in the planetary orbit of Long River, the anti-aircraft fire on Long River has hardly stopped.

And this intensity of fire attack makes Changhe Star scrap hundreds of cannon barrels every hour. The Long River Star needs at least thousands of new barrels to be replaced every day to maintain a high-intensity shelling action.

Even the Empire's sturdy barrels made of high-grade alloys are like cheap consumables that need to be replaced over time.

However, whether it is ammunition or gun barrels, there are a large reserves on the Long River Star.

Through the Sentinel Array, the news of the Zerg invasion has been known to the empire for a long time, and the Long River Star has stockpiled a large number of strategic materials during this time.

In terms of ammunition, the reserves of artillery shells in various cities of Changhe Star can at least last for decades of high-intensity artillery consumption. Moreover, Changhexing continues to produce new ammunition,

At present, more than 90% of the Zerg casualties are due to artillery shelling, and only a very small number of Zerg are casualties from the lasers and explosions of the Astral Army or Space Marines.

The artillery units on the Long River Star have plenty of ammunition and can put a lot of pressure on the Tyranids.

The main reason why it is difficult for the Tyranid to make tactical progress in the Long River Star is that the Imperial forces have an absolute advantage in artillery fire.

With the ability of the Eternal River Star's absolute artillery to continuously bombard, it is difficult for the Tyranid Zerg to break through the defense line of the Imperial forces by relying on the swarm charge alone.

If you want to exhaust the ammunition stored by Changhe Star, based on the average number of casualties of a shell at present, I am afraid that Changhe Star will blow up all the zerg in the entire White Deer Galaxy.

In addition to these artillery, which consumes ammo, the Empire also has a large amount of anti-aircraft firepower, as well as ground firepower, which is made up of energy weapons.

For example, laser cannons, ion cannons, plasma cannons, phase pyrolysis cannons, prism towers, electromagnetic coils, etc.

These weapons are not uncommon in the Empire's defenses.

"Trying to run out of ammunition for these weapons by relying on the number of biters" was enough to make any Imperial soldier who heard it laugh off his teeth.

There are plenty of engineers and parts on the planet to repair these energy weapons, as well as enough energy for these energy weapons.

Each city on the planet is home to numerous "artificial stars" that provide energy and store enough antimatter for these little suns to run for hundreds of years.

A series of power generation devices such as nuclear fusion reactors, thermal power plants, wind power plants, and solar processing arrays will not make Changhexing troubled in terms of energy.

And, most importantly, the Reich has bioreactor technology. This facility is an efficient conversion of organic matter into energy.

Unless the Zerg that invaded the Long River Star are dead, those energy weapons will be able to keep firing.

Therefore, if the Tyranid want to rely on the number of bugs to exchange ammunition for the Imperial troops, it is definitely beneficial to the Empire.

Unfortunately, this is not a tactic implemented by Tyron.

Only a fool would take the cruelty and bloodlust of the Tyranid as a sign of their lack of intelligence. The Hive Will coldly and precisely controls the activities of all Zerg communities to ensure the survival of the entire population.

There are so many of them that they devoured many galaxies before they came to the Milky Way. And now, they don't want to be held back by any resistance.

Beneath the planet, some Tyranid creatures are digging fast.

While the Knife Worm and Spear Worm attacked the human city from the surface, these other Tyranid creatures charged towards the human city underground.

They have evolved sharp claws and possess the ability to dig tunnels in almost any matter to advance forward.

The violent vibrations and noises produced by the artillery bombardment of the Imperial forces well concealed the ground tremors caused by the large-scale Tyranid biological excavations.

As the soldiers on the front line were celebrating that they had once again repelled the Zerg attack, the ground trembled faintly beneath their feet.

This was a precursor to an attack by the Tylen Diggers, who had been digging forward lately. But the soldiers of the Empire did not realize that this was an attack from the Tyranids.

Until the shaking became stronger and stronger, and the deafening noise sounded as if the ground was about to split in half.

A massive Tyranid creature crawled out of the ground, covered in gray dust, claws and fangs opening and closing in the air.

And that's not all, this large creature didn't just dig such a tunnel to show its strength in front of the Imperial soldiers.

As it broke through the ground, a tidal wave of Tyranid creatures began to emerge behind it.

A large horde of inferior Tyranid warriors swirled around its hooves. The Xenomorphs will do everything in their power to slay humanity and destroy all other creatures they see.

And these Tyranid creatures appear in very clever places, often near the defensive weapons that the Empire has laid out.

As more Tyranid creatures burst through the ground, they immediately began to attack the nearby turrets and energy towers.

When these defenses were destroyed, the Empire's forces were powerless to resist the massive swarms of giant Tyranid creatures.

"What!?"

"A massive Tyranid Zerg has appeared in the middle of the battle!?"

The front-line commander listened in shock to the urgent pleas for help from the soldiers on the communicator.

"That's right! They've broken through! ”

"Large and small digging insects, as well as an unknown number of soldier insects, followed along the tunnels dug by the big guys."

"Request for support! Request support! ”

The front-line commander who received the call for help immediately realized the seriousness of the problem. All front-line officers were immediately contacted and asked to rush to the designated location for support.

After turning on the hologram, looking at the red icons that suddenly flashed on it, the expression on the face of the front-line commander became very serious, and he quickly changed his previous order.

In more than one place, the entire city's frontlines have been invaded by a large number of Tyranid creatures.

This is no longer something that the planetary defense forces and the astral army can handle, and they must be dealt with hard.

Realizing the scale of the Tyranid invasion, the front-line commander who had re-entrenched all his troops in his zone immediately contacted General Wadez, hoping that he would send an armored army and notify the Space Marines to provide support.

But...

"What!?"

"General Wadez is rescuing!?"

"That's right, we need support! Immediately!!! ”

The front-line commander hung up the communication with an indescribable expression on his face.

At the time of the invasion of the Tyranid Zerg, the current Supreme Commander of the city actually fell!?

Luckily, Panzer and Space Marines have gotten the word that they're on their way.

"Guards! Prepare the transport, I'm heading to the battlefield! ”

The Frontline Commander swore in his heart that if the front line was lost, he would die on the way to charge the Tyranids.
