However, dropping bombs at high altitude is not absolutely safe, because Cai Tingyuan's troops are equipped with the latest Red Arrow 2 land-based air defense missiles, these missile units belonging to the Second Artillery Corps, their strike distance is more than 30 kilometers, the shooting height is also more than 10 kilometers, and the power of the air-burst warhead is huge, even if it is 50 meters away, it is enough to destroy a large bomber like the B29, and the Boston people have clearly seen the power of this new weapon for the first time. One of the fighter pilots also heroically rushed close to take clear aerial photographs.

After sending these photos back to China, the Boston Imperial Academy of Sciences began to develop missiles again, but they did not have much foundation in microelectronics, and the difficulty of developing missiles can be imagined.

The principle is clear, but if you want to make your own, it's another matter. The Boston Empire, which was unable to miniaturize electronic components and mechanical parts, had poor manufacturing process precision. Boston scientists soon discovered that if the missile was manufactured, not only would the missile be huge, but they could only install a simple gyroscope for navigation, and its accuracy was terrible.

The Bostonians still have a long way to go in missile development, and now they can only rely on existing equipment and endure huge casualties to bomb the Imperial Chinese Army. And Cai Tingyuan's blocking battle was not simply to stop the advance of the Boston Army, he was slowly torturing Patton's nerves, so that his fiery temper would burst out faster, and once Patton lost his cool, he would have a chance.

Sure enough, in the case of two days of unsuccessful attack, Patton withdrew the armies of all other countries, and in his opinion that only the real Boston army had the strongest combat effectiveness, and now the enemy's main force was on the other side of the river, it was an opportunity for the Boston army to show its skills, so he deployed all the Boston troops in the center, and let the troops of the Kingdom of Sero and the Grand Duchy of Rees cover the left flank, and let the troops of the Viking Kingdom and the Grand Duchy of Gothenburg cover the right flank, and the entire Axis army was ready to attack with all its might.

He has a lot of opinions about Mike's greed, and he actually wants to monopolize the credit on the Southern Subcontinent, so when Mike's army is trapped in Alexandra Harbor, Barton has some snickering joy. He knew very well that this was his chance, as long as he achieved enough combat merit before Mike freed his hand, even if Mike succeeded him in the future, he would be considered by others to be his credit.

Moreover, there is another possibility, since Mike is the commander of the Southern Subcontinent, Barton cannot resist his decision. But this time is different, Mike is trapped in the battlefield of Port Alexandra and cannot extricate himself, if he can defeat the main force of the Southern Military Region of the Chinese Army as soon as possible, he can take the greatest credit. Add to that Mike's loss, and you can rightfully take his place, so Barton has to start working hard.

Regardless of what Patton thought, what Cai Tingyuan wanted was for Patton to adopt this tactic, and after the Axis coalition began to mobilize troops, he obtained accurate enemy intelligence through satellites and black feather reconnaissance aircraft.

Armed with accurate intelligence, Cai Tingyuan began to secretly transport heavy armored troops from the upper reaches of the Nile. Cai Tingyuan's hands had always been in the hands of three heavily armored corps and two mechanized infantry corps that were not used, and after seeing Patton's military move, this most rearly reserve force finally began to move.

After crossing the river, the reserves did not attack Patton at the first time, but relied on the protection of camouflage nets and lurked far away from Patton's army. The frontal battlefield was fought for another whole day, and on this day the Chinese Air Force sent its own bomber unit for the first time, and the terrifying speed and huge bomb load of the Kunpeng 3 bomber made the Boston Army taste the bitterness.

To make matters worse, the fighter pilots of the Boston Air Force unexpectedly discovered that even without the Golden Eagle 4 fighters, it was difficult for the F84 fighters to shoot down the Kunpeng 3 bombers, which were about the same speed as them, so the Boston Army that was crossing the river was taken care of. A large number of armored vehicles were destroyed, soldiers were killed, and bombers using incendiary bombs burned two ammunition depots, much to the annoyance of General Patton.

By nightfall, the Axis forces were exhausted and no longer ready to fight, so Patton had no choice but to rest. At 10 o'clock in the evening, a Black-Feather strategic reconnaissance plane used synthetic aperture radar to reconnoiter the Axis forces at high altitude, and its position and troop allocation were quickly transmitted back to the headquarters of the Southern Military Region.

Under the guidance of the Black Feather reconnaissance plane and the high-altitude early warning plane, 80 Kunpeng 3 bombers flew into the sky, and their bellies were loaded with the latest new bombs developed by the Chinese Empire, but because it was not easy to manufacture, there were not many of them.

The Kunpeng 3 bombers were equipped with navigation radars, so they could fight in the air around the clock, regardless of the night, and when they flew over Patton's army, the rumbling sound of the plane woke many Boston soldiers, but they had no idea that the danger was approaching.

The Boston Air Force's radar also captured the bomber group of the Chinese Air Force, but because the Boston radar skills were not good enough, the jets of the Axis Army Air Force did not have the ability to fight at night, so they did not take to the air to intercept, and only General Patton gave the order to control the lights.

In General Patton's mind, if a night bomb was to be carried out, it was necessary to have lights to guide it, and if the lights were controlled in the camp, the bombers had no hope of finding their targets, especially temporary targets such as barracks.

But advances in science and technology often exceed people's imagination, and what General Patton thought was impossible happened. Relying on the detection of infrared down-looking radar, the bomber's bomber and pilot can clearly see the location of the ground target, but in order to drop the bomb more accurately, the pilot bombers still dropped flares hung by parachutes over the target.

Flares with parachutes drift slowly to the ground, and these aluminum-filled flares not only provide daylight but also last twenty minutes, which is enough time for bombers to drop bombs.
