Originally, the Japanese devils did not pay attention to air defense work, because in the impression of the Japanese devils, there were not many aircraft in the Chinese army. They slid down when the war just started, and all the air forces were only a few aircraft, and all the aircraft were biplanes from the First World War. What damage these aircraft wanted to cause to the Japanese devils was no different from dreaming. After flying up, many pilots were worried that the aircraft could fly back intact because there were no parts on it.

In that case, it would be nonsense if the Japanese devils paid attention to air defense. But later they gradually encountered the army of the security regiment. Before each attack, the security regiment army would definitely use the air force to sweep your positions, and then it directly evolved into sweeping all the roads, bridges, railways and some strategic areas in your occupied areas. If there were not enough air defense weapons, they would definitely lose at the beginning in the battle with the security regiment. The Japanese devils understood this very well, so they paid great attention to their air defense work later. But you understood the importance of prevention and control work. Your domestic production level was not up to date. This was also a big deal. Japan could only give them some air defense artillery, so they could only pay attention to some more important places.

At the beginning, there were many air defense artillery on the headquarters, but later it was found that China's aircraft were not empty. The headquarters mainly attacked transportation hubs such as airports and railway stations on their side, so they moved all air defense artillery to these places. It was because their air defense artillery was too dense that China's aircraft did not bomb their airports. Later, they basically used airships to bomb horizontally at high altitudes, and the effect was quite good. The Japanese devils dug many air raid shelters to hide their planes.

In addition, the Japanese devils also set up many observation posts at the junction of both sides. Once a large number of planes were found, they would immediately notify their planes to take off. After several such hide-and-seek games, the Chinese side also felt that if they continued like this, they would not only not clean the Japanese devils' air force, but the pilots on their side were exhausted, so they stopped this action, which allowed Hongqiao Airport to survive under the nose of the security team.

"Shoot." The Japanese devils on the edge of the airport had discovered small reconnaissance aircraft of the security regiment, so their anti-aircraft machine guns began to shoot at the small reconnaissance aircraft. The flames sprayed from more than a dozen anti-aircraft machine guns around formed a complete airspace. No matter where they flew, they could not fly over. If the altitude was raised, there would be anti-aircraft guns from the Japanese devils behind them. It can be said that it would be impossible for such a small reconnaissance aircraft to cross this protective net.

The Chinese reconnaissance department has encountered Waterloo today. They have released many small planes. They want to know how many air force the Japanese devils will dispatch this time. Unfortunately, the news they have received so far is only in some marginal areas. They can see the Japanese devils in large numbers on the airport, but the specific number is not estimated. Originally, as long as they could fly in, the number could be roughly estimated, and we can make arrangements here. Now we have to wait for the devils to fly and let the radar judge it.

There will be more than ten minutes in the middle. If the pilots can prepare for these ten minutes, the pilots can climb up to the high altitude and dive down at high altitude to attack the Japanese devils' aircraft group. This is a very precious ten minutes. Unfortunately, the Japanese devils have used their air defense team to fight back these ten minutes.

"The Air Force immediately changes its combat tactics. Don't continue to put small reconnaissance aircraft over. In this way, we will increase our losses. Order the airship to conduct a high-altitude bombing, focusing on bombing their air defense infantry, and put it in the small reconnaissance aircraft again. At the same time, order the airship to see if it can be seen clearly in high altitudes and increase the multiple of the telescope." After Mao Yuanshan knew this, he immediately ordered the airship troops and the air force to change their combat strategies. If he continued to follow the original combat strategy, he still could not find out the situation of the Japanese devils Air Force. The navy was also reporting. There were always Chinese submarines in the waters between China and Japan, which were responsible for reconnaissance missions, but they were weak and could not attack the Japanese fleet. Now the Japanese have learned their ability. Every time there were a large number of warships escorting. If they attacked at this time, they were seeking death.

At this time, Mao Yuanshan also felt that there was a lack of a submarine supply port near the route. If a submarine supply port could be built in central China, these submarines could attack the Japanese transportation lines 24 hours a day. However, now is not the time to consider that thing. The most important thing to consider is to figure out the Japanese army’s real actions in central China this time, rather than guessing as confused as it is now.

"Reported to the commander-in-chief, according to the reports of our three radar stations, a total of more than 600 Japanese aircraft were monitored, and the number of aircraft continued to increase. They were coming towards our position. Did we order our air force to attack? At present, 400 of our fighters are ready for combat over the battlefield." The officer in charge of radar monitoring immediately sent Mao Yuanshan the latest data and dispatched 600 combat aircraft at once. It seems that they are not Japanese. When did they do things so generously? It turned out that even if they provide air support, they would only dispatch dozens of aircraft at most. I really didn't pay attention to this period of time. They actually transported so many aircraft.

"The Japanese are actually looking for death, and we have to save them. They ordered our brothers in the Air Force to immediately lower the flight altitude and attack them, and try not to let them fly to our positions." Mao Yuanshan issued an attack order to the Air Force. At the same time, at 7,000 meters in the sky, hundreds of fighter jets of security regiments drew a beautiful arc and began to fly towards the Japanese army.
