Create a swarm technology tree in Konoha

Two months before gaining the upper hand in the air battle, the Red Army's army had already gained absolute advantage in the ground war. They defeated the newly established Sark Empire army and advanced on the "last castle" of the empire.

The castle complex stuck between the mountains and the sea was suppressed head-on by 20,000 red-coated troops, and they could only rely on multiple solid walls to offset the opponent's offensive.

Fortunately, this solid fortress group has its own advantage that cannot be ignored, and that is the Sac Empire Army with a total number of 160,000.

This group of fortresses has a wide front and a complete defense system, which can completely shield the front of the Red Army and provide sufficient protection for the territory of the Sac Empire behind it.

As a result, this fortress group can receive sufficient supplies. Food, weapons, soldiers, and even building materials are continuously transported to replenish the losses of the fortress group at any time.

The Red Army attacked the fortress a month after the war started. After destroying two walls, the dragon and the defenders cooperated to defeat more than 4,000 people, and suffered a big defeat.

After that, the red-coated army stationed its troops under the city. There was no progress for two whole months, and they did not even try to launch an attack. They bombarded the castle complex every day.

That victory was promoted as a great victory by the Sac Empire, and a series of victories were completed on paper thereafter.

The great victories were hearty and hearty, and the Red Army, which had been replenished to 20,000 people, was "annihilated" more than ten times.

The commander-in-chief of the castle was a candidate for the imperial emperor, and the elector Margrave de Beaumain became famous because of this, and was called the "Wall of the Empire" and the "Great General".

Even the current emperor Paul felt threatened and began to worry about Boman's reputation for victory and ousted him from the emperor's throne.

After all, this was a deformed empire that was forcibly put together by the gods and aimed solely at the Red Dynasty's capital empire militarily. Even the gods had not figured out the operating rules of the centralized dynasty.

Therefore, the various core political rules are still the same as those of the traditional aristocracy. At most, they learn from the system of the Chi Dynasty Empire and form a centralized shell.

So in the imperial court, the nobles started to act according to their habits, and some unspoken conspiracies began to brew.

Some were directed at Emperor Paul, and some were directed at the Grand Marquis Portman. Seeing that a coup that could be debated by the nobles for a hundred years was imminent.

But the Marquis of Portman no longer cared about this at all. Although he was a mess militarily, his political acumen was quite good.

He has realized that the core essence of the centralized empire is still violence, but the carrier of violence has changed from domestic knights to imperial professional legions.

The Marquis of Portman thought clearly that as long as he could firmly control the hundreds of thousands of troops in his hands, the empire would be his own.

As long as the red army retreats, he can kill Paul at any time, so there is no need to worry.

The key to everything lies only in the army, military morale, and Boman's reputation.

Coupled with the "victory" that lasted for two months, the Marquis of Portman could no longer see the fatal crisis approaching, so he optimistically declared: "In the end, the castle will be able to hold on forever, no matter whether it is autumn or winter."

"When winter comes, the hateful enemy will be frozen to death by the cold winter wind under the city wall!"

The core meaning of this sentence is that he does not have the slightest confidence to defeat the Red Army.

His expectations for victory were all pinned on the cold weather that would enter winter five months later.

One thing that the Marquis of Portman did not realize at all was that the Sac Empire was a warm area with low latitudes, almost no snow in winter, and very little ice.

However, most of the Red Dynasty Capital Empire controlled by the Red Army will have snow, and there are even cold areas where the snow will not melt in April.

As winter really drags on, it will definitely be even more difficult for the Sark Empire's army to withstand the cold invasion.

Moreover, there is a qualitative difference between the Chichao capital empire and the Sak feudal empire, and the two sides' ability to mobilize national power and resources is even more different.

In the cold winter, there is no doubt who will be frozen to death.

…

It's just that Aburame Tetsumaru couldn't accept the war being delayed for such a long time, and the thirteen chaebols who controlled the capital also used their instinctive efforts to promote the rhythm of the war.

They have invested too much in the war, and these immature capital beasts have already felt guilty. Only by ending the war as soon as possible can the currently occupied areas be turned into profits.

It's just that only by ending the war with a victory, or a greater victory, can they exchange for the maximum profit.

Therefore, the capital plutocrats gritted their teeth, squeezed their own potential, and supported the attack on the last fortress.

Fortunately, this day has finally arrived.

The fundamental reason why they were unwilling to launch an attack before was because the dragons had control of the air.

By controlling the sky, these giant lizards can attack the Red Army at any time, forcing the Red Army to be on alert at all times, seriously draining the soldiers' spirit and weakening their combat effectiveness.

Especially after approaching the fortress area, the dragons can use mountains, castle towers, etc. to hide themselves, and then launch a sudden attack, so that the red army has no time to react and will be attacked by the dragon's breath.

Now, the Air Force has spent two months using sacrifice and courage to forcefully drive the dragon out of the sky of this battlefield.

In just two months, the newly born Air Force lost seven air force commanders, three of whom died in battles with giant dragons, and four who died in takeoff and landing accidents.

In similar accidents, there were five other commanders who survived because they were not very fast, but lost their limbs or eyes, or had their internal organs severely damaged, and had to retire.

The sacrifices made by the Air Force are not small.

This is because the Air Force recruits lunatics who are not afraid of death, and there are also problems with the aircraft itself.

The biggest problem is that Aburame Tetsumaru has not found reliable oil. It is not that there is no oil, but it is sparse and scattered, and has no mining value at all.

So much so that the vehicles used by the Red Army were still bulky and steam-powered.

However, the Air Force cannot use steam engines because the power/weight ratio cannot be reduced. Moreover, water and coal are used as working fluids, and the heavyness is not acceptable for aircraft.

The Red Army's air force initially chose coal tar, which had insufficient energy density, was prone to carbonization, and easily induced malfunctions. In actual combat, it was completely abused by the giant dragon.

Later, soybeans were converted into fuel oil, and a large amount of unsaturated acid soybean oil was charged into the reactor, hydrogenated, pressurized and heated, and cracked under the influence of a catalyst.

What flows out from the outlet of the reactor is standard alkane aviation diesel, mixed with a small amount of pure alcohol, which is an ideal internal combustion engine fuel.

With the right fuel, Aburame Tetsumaru came up with a suitable piston engine, and a mature fighter design was not a problem.

The descendants of Zhou Civilization, in the early days of developing the industrial system, restored and verified all types of aircraft from the World War II period, and the relevant data is very rich.

The P-51 Mustang, or a piston fighter that looks like a Mustang, became the Redcoats' best choice.

As a result, they were completely unable to defeat the giant dragons in the fight, but they had obvious advantages in straight and high-speed flight. Therefore, the tactic of flying high, diving and flying away in one hit was widely used, and finally the dragons were beaten with their heads covered, and they headed southeast. The dragon's nest was moved.

With air cover, the real land monsters can emerge.

Twenty Yugong-type siege artillery were sent to the front line by steam trains. It took a day to unload them and then slowly rushed to the fortress group at a speed of three kilometers per hour.

There's no way, these big guys really can't get up fast.

A giant carrier vehicle with a total length of 41 meters, a width of 9.4 meters, four tracks, and a dead weight of 640 tons can only go so fast.

Even if the six boilers are fully powered and the thick black smoke from the six chimneys rises to a height of 600 meters in one breath, it can only drive this big guy forward at a speed slower than a person walking.

Because it carries a huge cannon with a caliber of 380 millimeters and a weight of 330 tons, as well as those cannonball warheads that weigh one ton, it would be damned if it could still run fast.

In addition to these heavy artillery, there are also more violent throwing bombs, one weighing fifteen tons.

Only a hundred-armed giant heavy-duty aircraft that has removed all its weapons and equipment, and even part of its body shell, can meet the load requirements for carrying a bomb.

These extremely violent things arrived at the front line on July 25th. Before that, more ordinary ammunition was transported to the front line and distributed to each artillery position in a concealed manner.

The siege guns slowly entered their respective fighting positions. The heavy brackets and cannon hoes were inserted deeply into the ground, tightly fixing the gun body and body.

As the order was given, the bombardment began.

A clear rhythm of shelling sounded from the cannon position. The strong wind from the muzzle blew the ground as if it was hit by a bomb. The sand and dust within a circular range were stirred up and then blown away.

The bombardment follows a strict plan, with older guns with lower projectile flight speeds or siege guns with longer ranges firing first, and then various other types of artillery taking the floor according to time.

The shells were in a dark red blazing state, spinning at high speed towards the target area.

A few seconds later, dense firelight jumped out of the fortress group. It was a scene of artillery shells falling to the ground and exploding within two seconds.

These large and small shells hit the target like raindrops. Because long-delay detonation fuses were uniformly used, all the shells penetrated deeply into the target, and then formed an internal explosion inside.

The same explosion occurs on the surface and occurs inside, and the damage caused is completely different.

As a result, the castle that was said to last for thousands of years collapsed, just like the sand sculpture castle on the beach that was kicked by a child.

The huge rock blocks that built the castle were blown away, and the walls and the main building of the castle obviously collapsed. Miserable cries immediately erupted from inside. It is unknown how many people died in this round of shelling.

Planes appeared in the sky, and they judged the effect of the bombardment based on the different impact points and recorded it. Finally, they dropped these records when flying over the headquarters.

Based on these records, the artillerymen of the Redcoat Army fine-tuned the muzzle parameters, then fired a second salvo, and then adjusted again and fired a third salvo, finally confirming that the accuracy of the artillery fire had reached the standard.

Then it was about playing it casually, pursuing the goal of firing out all the cannonballs as quickly as possible to cause maximum damage and casualties to the enemy.

The dense artillery on the artillery position opened fire rapidly, and the red warheads followed a fixed arc, spanning a distance of six kilometers, covering the target fortress group he had selected in advance.

After receiving the alarm, Marquis de Portman hurriedly put on his shirt, coat, linen smock, and thick armor with the help of his servants.

By the time he finished all this and came to the balcony with a slightly hurried pace, the first half of the fortress complex was completely shrouded in gunpowder smoke.

But the shells are still like meteors, scrambling to get into the smoke-filled battlefield, harvesting lives and destroying buildings.

The stunned Marquis de Portman was completely dumbfounded. His mind went blank and he could not think about anything, as if he had lost consciousness after drinking.

Not only the Marquis, but in fact, all the officers in the Sack Empire army did not know what to do. They stood together like meerkats, staring at the explosion in front of them in a daze.

But the Red Army had no idea of ​​letting the enemy appreciate it, and the artillery shells from industrial products began to extend their strikes backwards.

Just when the officers of the Sack Empire were at a loss, a heavy buzzing sound sounded, and the modified Hundred-Armed Giant aircraft flew over the fortress group.

It was the first time for the pilots flying the plane to see such a large-scale bombardment, and they were all shocked and uneasy.

The officer in charge of the navigation was the first to get rid of this abnormal emotion. He loudly woke up the pilot who was shocked and stunned.

Then the officer shouted loudly: "The artillerymen showed us what a coverage strike is, now let us show the artillerymen what the power of the King of Bombs is."

"Now! Drop the bomb!"

The bombardier moved the mechanism as ordered and dropped the huge fifteen-ton steel column.

The first Bomb King unexpectedly fell into a castle, and the next second the entire castle unfolded like a blooming sea anemone.

Every boulder was shattered by the shock wave of the explosion and turned into fist-sized gravel, flying all over the sky.

But the perfectly shaped gravel was instantly destroyed by another explosion, and then one bomb king after another fell, setting off a torrential rain of gravel flying in the sky, and more complete destruction.

Marquis Bomain shivered violently, and he shouted tremblingly: "Come and help me take off my armor, let's go, we will retreat immediately!"

The generals around him were also waking up from a dream, howling words such as "retreat" and frantically calling on the soldiers to help them retreat.

Now, no matter what kind of honor or noble demeanor, I don’t care about anything else. If you wait any longer, you will die!

But it was too late. A King Bomb penetrated the ground diagonally from the outside of the castle wall, and penetrated straight into the underground prison of the castle.

The next moment, the entire castle fell to one side as if it had been tipped over by an invisible shovel, turning into a large pile of building ruins.

The Marquis de Beaumain and his trusted officers and generals were not able to escape. They were buried under the rubble together with the order to retreat.

The unprecedented density of shelling and shocking bombings caused the defenders of the fortress group to lose their structure, turning from defenders of the empire into helpless stragglers.

This fortress group no longer has the ability to resist.

But what Aburame Tetsumaru valued most was the shock that this huge scene had on people's hearts. The red-coated soldiers and the soldiers of the Sac Empire who witnessed this bombing all had an idea in their hearts.
