On February 25, on the front line of Tierra Cororada, the artillery of the Chinese Army was still shelling the No. 1 high ground of the American army. It's just that after the appearance of the U.S. airship unit, the Chinese Air Force's airship unit barely appeared in Tira La Corollada to bomb the U.S. military. This is because the US airship unit has always kept dozens of ships in the sky over the Tierra Corolada, and once the airship unit of the Chinese Air Force appears, it will attack the airship unit of the Chinese Air Force, and at the same time, the main force of the US airship unit in Chilpancingo will also arrive within an hour. The commander of the squadron, Marshal Zhao Bo, was unwilling to let the precious airship suffer losses, so he did not ask the airship troops to participate in the battle.

Even though the airship unit did not participate in the war, the army's artillery was still bombarding the American troops. Because the heavy machine guns equipped by the Chinese army can pose a threat to the US airship units, the US airship units can only drop bombs at an altitude of more than 1,500 meters, and the threat to the Chinese army and Japanese mercenaries is very limited.

After the shelling, the Japanese mercenaries continued to attack, continuing to consume the vital strength of the American army. It's just that without the bombing of the airship troops, the morale of the US military has risen a lot, and it is difficult for the Japanese mercenaries to take advantage of anything.

"Your Excellency Marshal, isn't the airship unit of the Chinese Air Force going to go to war? If it loses air supremacy, it will be very difficult for the squadron to break through the Sierra Madre do Sul! Major General Haines, the head of the German Observer Mission, asked. The arrival of the U.S. airship force returned the air supremacy of the battlefield to the U.S. military, which made Major General Haines and other German officers more firmly believe in the importance of seizing air supremacy. On the battlefield of the European war, the two sides are still fighting trench warfare. China and the United States, on the other hand, have already begun to compete for air power. This made it difficult for the German generals who thought that the military strength was the first. Therefore, Major General Haines repeatedly sent telegrams to the Chief of the General Staff of the German Army, Falkenhayne, hoping that Germany would strengthen the development of air power. And his construction was also recognized by Falkenhayn and Kaiser Wilhelm II. The German side has already asked several major German weapons manufacturing companies to come up with a design plan for a new airship. The United Kingdom and France are also of particular concern. The two countries have also carried out the development of airships before, but they have not paid attention to it. The importance that China and the United States attach to airships on the battlefield has also attracted their attention. Both countries have also come up with plans to build airship units.

"General Haines, the Americans have assembled hundreds of airships here. According to the information we have received, there are still a number of airships on the way by the US military, and it is estimated that there are hundreds of them. Although the mass of our airships is much higher than that of the Americans, the quantitative gap is simply too great. In order to avoid unnecessary losses, our airship troops will not be in battle for the time being. As for whether it is possible to break through the defense line of the US army in the Sierra Madre do Sul. I have a lot of confidence in that! Marshal Zhao Bo said confidently.

"Oh? Then I wonder what measures His Excellency Marshal has to counter the US military? Major General Haines asked. He was very curious about this, the US army has strong fortifications, and at the same time has a great advantage in terms of strength and logistics. Now that it has air superiority again, in the opinion of Major General Haines, it may be even more difficult for the squadron to break through the defensive line built by the American army! He really couldn't understand where Marshal Zhao Bo's confidence came from.

"Major General Haines, you'll find out tomorrow!" Marshal Zhao Bo smiled. Didn't explain much.

Marshal Zhao Bo's words made Major General Haines very puzzled. Could it be that the squadron has already found a way to seize air supremacy? Or is it that China has transported a large number of airships from the country to compete with the US military for air supremacy? But. Mexico is closer to the United States, and with the strong industrial power of the United States, it is enough to produce more than 200 or more airships a month if it is at full capacity. Chinese airships, on the other hand, need to be transported from the earth. In such a case, the consumption of the spell airship. It is very difficult for China to fight the United States. However, Marshal Zhao Bo was so confident that Major General Haines couldn't help but believe that the squadron would have a way once it was ready. Fortunately, the answer will be revealed tomorrow, otherwise Major General Haynes would definitely not be able to sleep because of this.

On February 26th, the weather was clear with only a slight breeze, and it was a good weather for flying. If it had been some time ago, the airship units of the Chinese Air Force would have already been dispatched and began to bomb the US defense line. However, now the sky is occupied by American airships.

On the field airfield south of Acapulco, forty fighters of the 2nd Group of the 4th Fighter Wing of the Chinese Air Force had been assembled and parked neatly at the airfield. Ground crews are conducting pre-takeoff checks on fighter jets. In addition, the airships of the Air Force's airship unit had already departed twenty minutes ago, and this time, the US airships would be dealt with by the Air Force's fighters, while the airship units would continue to bomb the positions of the US troops. With fighter planes escorting the airship troops, the US airship units will not pose any threat to them.

At 8:20 a.m., the fighter planes piloted by Major Huang Qiuming, the commander of the group, first took off from the field airfield, and then all 40 fighters of the entire group took off within 20 minutes, and after marshalling in the air, they began to fly eastward. At this time, the airship unit of the Chinese Air Force was only more than ten kilometers away from the Tiela Corolada, and the airship unit of the US military had already discovered the airship unit of the Chinese Air Force, and was preparing for an air battle while sending a telegram to Chilpancingo's airship unit. With a huge numerical superiority, the confidence of the US military has also been greatly improved.

Colonel Eebt served as the commander of this unit of fifty airships, and although his unit had lost 80 percent of its airships in the last air battle, he was undoubtedly the only commander of the American airship unit with experience in air combat. Because, under the advice of Admiral Pershing, Major General Carter, commander of the US airship unit, supplemented Colonel Ebutt with forty airships, and put him in charge of the defense of the skies over Tyrana Corolada and the task of monitoring the Chinese airship unit.

"Attention airships, rise to an altitude of 1,800 meters, pay attention to the anti-aircraft machine guns on the ground of the Chinese. Send a telegram to General Carthus, the Chinese airship has appeared, we need support! Colonel Ebbt ordered. This time, he did not have the courage to engage in an air battle with the airship units of the Chinese Air Force with the current fifty airships. The last time he was defeated, this time he had to wait at least until the arrival of the large army before he dared to launch the kilogram.

At 8:50 a.m., it had been less than five kilometers since the airship units of the two sides had gathered, and the remaining airships of the American army had already taken off from Chilpancingo and were heading for Tierra Cororada. It's just that it will take an hour for them to reach the battlefield. Major General Carter, commander of the US airship unit, ordered Colonel Ebutt to preserve his strength and not to fight hard with the Chinese airship force.

Colonel Ebutt received the order and ordered the troops to retreat to the east, waiting for the arrival of the main forces.

On the ground, the officers and men of both China and the United States watched this scene in the sky with their eyes wide open. They are all expecting the outbreak of a large-scale air battle. The military observer missions sent by Germany and the Entente countries are also paying close attention to this qiē. In particular, the German observation group wanted to see how the squadron would recover its disadvantage and seize air supremacy.

At this time. Forty F5 'Haidongqing' fighters of the 2nd Group of the 4th Fighter Wing of the Chinese Air Force are rushing towards Tira La Coroda at a cruising speed of 100 kilometers per hour, and it only takes half an hour to travel from Acapulco to Tira La Corollada.

At 9:10 a.m., a group of small black dots appeared in the western sky, and these small black dots were rapidly approaching, but because the size was too small and the speed was too fast, the US airship saw the approach of these small black dots, but did not realize the coming crisis.

At 9:15 a.m., Major Huang Qiuming of the 2nd Brigade gave the order for a free attack. When dealing with enemy fighters, in order to ensure safety, most of the time they will attack in the form of a two-plane formation, but against these slow airships, each fighter can act on its own.

"Huh? What is that? The crew on a US airship, seeing the small black dot getting closer and closer to them, immediately picked up the binoculars, and suddenly, the figure of the fighter of the Chinese Air Force was extremely clear in the Yan zhòng of the crew of the US airship.

"Airplanes! The planes of the Chinese are coming! The crew shouted. Because airplanes have appeared on the European battlefield, but most of the European planes are used for reconnaissance, and their performance and style are different from those of Chinese fighters, but this does not prevent the US military from recognizing this as an airplane.

"Damn! Airplanes, the Chinese actually used airplanes! And these planes seem to be very difficult to deal with! Colonel Ebutt also said with some concern.

By this time, the fighters of the Chinese Air Force had already dispersed and pounced on the US airship.

The fighter rushed towards the US airship at high speed, and when it was a few hundred meters away from the US troops, the 127-mm heavy machine gun in the nose opened fire fiercely, and a series of bullets were fired out, and the US airship suddenly became a fireball. After destroying an airship, Chinese Air Force fighters pulled up the nose of the aircraft and searched for targets again.

At this time, there were only 50 US airships in the sky of Tierra Cororada, and there were 40 fighters of the Chinese Air Force. In the face of the fighters of the Chinese Air Force, the US airships were powerless to fight back, and they were shot down one after another. The sky of Tiela Corollada once again belongs to the Chinese Air Force!
