The last sixty thousand Serres gathered together in the scorching sun. The residents of the city supported their troops and helped the army dig a large number of trenches and build firepower points. The entire scorching sun was so fierce that when the Yaman army arrived at the periphery of the scorching sun, it was already here.

A defensive position with a depth of up to five kilometers miraculously appeared.

A large number of artillery soldiers from the 300,000 Yaman Army began to shell the scorching sun. Due to truck dragging, many large-caliber howitzers could operate with the troops, and there was sufficient ammunition. This large-scale shelling lasted for two hours.

, and the outer positions of the Serg army were in a mess, and then the Yaman soldiers began a cluster charge.

Just when the Yaman army attacked the Grand Duchy of Sel, on the border between the Yaman Empire and the Nantes Empire to the east, in order to support the defense of the Grand Duchy of Sel, the Nantes army began its first assault, and for the first time they

After purchasing the Chinese Empire, the chariot renamed the ft17 type was sent to the battlefield and started a full-scale assault as a cover force of infantry.

The Yaman Empire also placed heavy troops on this line. Seeing that the Nantes Empire started an attack, the Yaman Empire did not defend, but took the initiative to attack. It was also purchased from the Chinese Empire and was named the I-type chariot.

Under the cover of the Yaman soldiers also rushed up.

The chariots of both sides quickly tangled together, and launched close-range shellings with each other, and the world's first tank battle began. The shells flew around and machine guns fired, and the soldiers on both sides were killed and injured in large numbers.

Grenades and explosives have become invisible killers of both sides' chariots.

Yaman soldiers quickly used their new tactics, and the dense cross-fire strafing of machine guns caused heavy casualties and injuries to the Nantes soldiers, and finally had to retreat.

Then the Yaman Army began to shell the Nantes army. The Nantes Empire was not willing to be outdone and sent their airship troops to repeat the scene of the Yaman Empire on the border of the Grand Duchy of Ser, but unfortunately they didn't know that as the Chinese Empire

How could the treatment of a business partner and a friendly country be compared with those of them who have always been hostile to the Chinese Empire?

The Yaman Empire was equipped with the fourteen-mm large-caliber anti-aircraft machine gun secretly provided by the Chinese Empire. Although the anti-aircraft machine gun was not similar to that of the later air force. At most, it threatened low-altitude helicopters. In this era, it was flying in the air.

It is only eight hundred meters high and very fragile airship.

When the Nantes Empire's airship arrived over the Yaman Army and was about to drop bombs, dozens of flames suddenly spurted out from the ground, and the fragile airbags were punched into a series of holes.

Fortunately, the airship design concept of the Chinese Empire is very advanced. The airship airbag is composed of many small airbags. This is similar to the watertight compartment of the warship, so that even half of the entire airbag can fly, it can still fly, but the altitude will slow down.

It's just lowered.

Seeing this situation, the captains of the Nantes Empire's first reaction was to run fast, but the airship was already slow. This time, the battle was flying with full loads, and some of the airbags were destroyed.

Not only did these airships not fly fast, but their altitude was also decreasing. Many smart captains immediately began to throw bombs around to reduce weight. At the same time, they directed their airships to retreat in the direction of their own positions at the fastest speed.

At the beginning, the airships imported from the Chinese Empire were only hit, except for the reduction of buoyancy. However, when a Nantes Empire imitated airship was hit by the airbag, the tragedy happened.

Although a few airbags are hit and still do not reduce much buoyancy, due to technical reasons, these imitation airships do not have double-layer shells. The outer layer of the double-layer shell of the Chinese Empire airship is a hard shell made of aluminum, with a large spacing inside.

It is used by maintenance personnel to perform emergency repairs on airbags, and the inner layer is the real airbag.

Since the electrolytic purification technology of aluminum is a confidential technology of Chinese consortiums, although countries can use chemical methods to produce aluminum, the cost is too high. Such high-cost metals obviously cannot be used on such huge weapons. Otherwise, governments will be poor if they start a war.

The pants were removed.

It is not the most deadly thing to do without a double-layer shell. The worst thing is that helium is also a secret of the Chinese consortium, so these imitation airships use hydrogen.

The production of helium requires many advanced equipment and harsh conditions. To produce hydrogen, only by putting zinc crusts into concentrated sulfuric acid, which is simple and easy to use and affordable. However, hydrogen also has its own disadvantages because it is flammable.

It is prone to explosion, and it is easy to explode after encountering open flames or mixing with oxygen to a certain concentration.

Therefore, when the tracer bullet of the anti-aircraft machine gun penetrates the airbag and the flammable hydrogen hits the oxygen in the air, a big explosion is inevitable.

The airship hit was like a huge air torch, and it started to burn quickly. The fire was so big that it was impossible to react.

The flames quickly spread to the entire airship, and some crew members jumped from hundreds of meters high with fire, falling into a pile of meat paste.

The entire ignited airship quickly fell to the ground and continued to burn. The hot flames even completely melted the steel frame of the airship and completely collapsed on the ground.

Seeing this spectacular scene, the soldiers on both sides stopped shooting, and everyone held their breath and looked at the tragedy on earth in front of them.

After this battle, countries finally knew why the Chinese Empire did not use lighter and cheaper hydrogen, but used helium with low buoyancy and expensive.

Nowadays, countries have no means to produce helium. This is the unique trick of the Chinese Empire. If you want to use helium to fill airships, the high price is enough to shock the governments of various countries.

The helium that an airship needs to be charged is enough to build a large ocean-going torpedo boat. Moreover, the airbags often need to be replenished. Once partially destroyed, they will have to be reloaded after they come back. Such a high price is not something that countries can afford.

Therefore, after the Yaman Empire used anti-aircraft machine guns, countries began to develop their own large-caliber anti-aircraft machine guns to counter the other party's airships, which is also a remedy for the insufficient number of expensive airships.

As countries are vigorously developing air defense weapons, the situation of airships is becoming increasingly dangerous, but the biggest danger of airships still comes from the air.

When the Saar Empire first used the machine guns on its own airship to attack the invading Yaman airship, the real air battle began.

Airships from all sides fought hard in the air, greatly increasing the loss of airships. However, if you buy airships from China, let alone the transportation is insufficient, the finances of various countries cannot afford it.

Even if the airships were copied by each country, the nylon material used in the airbags was imported from the Chinese Empire, so the countries had to sacrifice their personnel and continue to use hydrogen airships.

The direct result is that the airship operators are short. The personnel who have just completed training may be killed if they fly once or twice. In the end, the airship crew will be collectively stopped flying. Unless the country uses helium balloons, it is better to be engaged in military law than to be promoted.
