When it was light outside, the Boston soldiers knew that something was wrong, but they had no chance of escaping. After identifying the target, the Kunpeng 3 bombers opened their magazines one after another, slid huge and outrageous bombs out of the magazine, and dropped them from a high altitude to the ground with parachutes.

These bombs quickly exploded in the air ten meters above the ground, but the explosion did not make much noise, only the milky white cloud-like substance in them was thrown in all directions by the power of the explosion.

Then there was a second explosion of these clouds, although the movement was still not large, but the light of the explosion was unusually bright, almost eclipsing the flares, and when the first bombs exploded, the flares that could have been able to support for more than ten minutes were also extinguished instantly.

This situation also surprised the pilots of the Chinese Air Force, because it was the first time they had used these strange bombs. Regardless of the situation, they still follow the protocol and use radar to drop bombs at high altitudes, dropping bombs on designated targets one by one.

These surprisingly small bombs made the Bostonians feel relaxed for a while, and the soldiers in the distance laughed at the Chinese Empire's bombs for not being able to make them, and the power was so small, but soon they couldn't laugh anymore.

Because in the area around the bomb, the moment the bomb exploded, the soldiers suddenly felt that the temperature was rising rapidly, and there was a burning sensation in their throats. They tried to take a big breath to relieve the feeling of stuffiness, but they were horrified to find that the air around them seemed to disappear, and no matter how hard they tried, they couldn't breathe any air.

The soldiers who fell to the ground blushed, they desperately tore their collars and throats, as if they could breathe air, and some soldiers even scratched their necks and exposed their tracheas to the air, this is still the situation in the area a little far from the center of the explosion, because in the center of the explosion, those soldiers, weapons and various materials have been turned into charcoal in an instant, and the whole scene is miserable, as if they have entered purgatory in an instant, this is the great power of the cloud burst bomb newly developed by the Chinese Empire.

Cloudburst bombs, also known as air bombs, have a main charge of a high-energy fuel known as a cloudburst agent, rather than an explosive. Explosives rely on their own oxygen during a detonation reaction, while cloudburst bombs make full use of the oxygen in the atmosphere in the explosion zone when they explode. Under certain detonation conditions, the cloud explosive agent is thrown away, mixed with the air and violently explodes, which is called cloud detonation.

The destructive effect of cloud detonation on the target mainly depends on the overpressure and temperature field effects generated by the detonation, as well as the scouring effect of the detonation products of high temperature and high pressure. Since the cloud explosion will consume the surrounding oxygen, it can form an oxygen-deficient area within the area of action, suffocating organisms to death, which is also the main killing method of the cloud burst bomb.

The lethality of the cloudburst bomb is very huge, but unfortunately it is also quite difficult to manufacture, even the strong industrial capacity of the Chinese Empire cannot be mass-produced at present, like this only medium-scale campaign, which has consumed all the production reserves of the Chinese Empire for a year.

In just a few minutes, more than 100,000 Boston troops were killed, and the entire Axis center battlefield was plunged into panic and chaos, but the real attack had just begun. Taking advantage of the lack of time for the Bostonians in the center, Cai Tingyuan's reserves began to attack, and the direction they chose to attack was the army of the Kingdom of Sero and the Grand Duchy of Rees, which were on the left flank of the Axis army.

Patton's use of other countries' armies to cover flanks exposed fatal flaws, especially at a time when the soldiers of the Kingdom of Sero and the Grand Duchy of Rees had begun to be hostile to the Bostonians.

In the face of the powerful armored firepower and rapid assault tactics of the Chinese Empire, these troops, who did not have much will to fight, had a very weak will to fight, and their defense line was quickly broken through, and then the Bostonians, who were still in a panic, were fiercely attacked from the flanks.

In conjunction with the assault operation of the reserves, the main force of the Chinese Army defending the Nile River also began a counterattack on all fronts. Taking advantage of the chaos of the Axis armies and no one paying attention to the river banks, they used folding assault boats to quickly cross the Nile and attack forward, while the engineer units also used bridge vehicles to transport a large number of armored troops across the Nile one after another.

The strength of the two sides was already about the same, and after several heavy casualties, the Axis coalition had lost 170,000 soldiers, and the remaining less than 300,000 troops had lost their formation.

General Patton, the commander-in-chief of the attack, could no longer prevent the rout of his own troops, and the entire Axis Southern Route Army was completely destroyed. And the Axis air force units on the rear airfields were miserable, the whole army was fleeing, who had time to inform them, so when these air forces stationed at the front-line airfields woke up, they suddenly found themselves on the front line.

The encircled Imperial Chinese Army did not give them time to wake up, so with the exception of a few remote airfield planes that fled, a large number of Axis aircraft and all ground support and cover forces, including hundreds of anti-aircraft guns, became trophies of the Imperial Chinese Army.

The rout of the Southern Route Army also made Mike, who was trying his best to attack, much more restrained, and in fact he was already overwhelmed by the street fighting in Alexandra Por, especially the natives who were desperate to defend their homeland, which was a nightmare for Axis soldiers.

Now with such a good excuse, General Mack immediately ordered the troops to get out of the battle, and the whole army retreated 50 kilometers to build a defensive line, and at the same time the troops extended south to meet the Patton troops of the Southern Route Army, and General Patton became the scapegoat for this defeat, and was directly dismissed by Mack.

Cai Tingyuan relied on skillful tactical command to defeat the Southern Route Army of the Axis Southern Subcontinent Front Army in one fell swoop, and killed and wounded a large number of its personnel, so that the troops of the Southern Military Region of the Chinese Empire, which were originally at an absolute disadvantage, gained a certain advantage, and after a series of skirmishes, the two sides formed a confrontation situation along the vicinity of Alexandra Port.

The veteran Cai Tingyuan's outstanding performance in the Southern Military Region made Fang Ruijun breathe a sigh of relief, at least in the direction where the troops were weakest, the battle situation was temporarily stable, but in the Central Continent battlefield, the pressure on the Imperial Army was much greater.

On the battlefield of the Middle Continent, the armies of the Sahr, Nantes, and Boston empires joined forces and launched an attack on the Cossack Empire and the Istanbul Empire from three directions. In addition to the alternative Cossack Empire, this is basically a war between the yellow race and the white race, and it is also a comprehensive collision in terms of geography, race, politics, economy and military, and the main battlefield of this collision is in the Middle Continent.

Battles on land were raging, and although the main fleets of each country were not dispatched at sea, some of the small fleets had begun quite fierce contact battles with each other, and these battles were small in scale and did not matter whether they succeeded or failed, but this was not the case with submarine attacks.

Due to the thorough preparation in advance, the nearly 300 submarines owned by the Axis powers had already been deployed to the stormy ocean, the Mediterranean, and even the southern and eastern oceans, but the chances of these submarines were not very good. Although the scientists of the Boston Empire tried their best to carry out research, because they started too late, even the countries of the Western Continent were blank in terms of submarines, and the only reference that could be made was the old Seawolf 1 submarine sold by the Chinese Empire, so their development progress was very slow.

The period of vigorous peace, from the end of the First World War to the beginning of the Second World War, was only enough for the Boston people to master the skills of the Seawolf 1 submarine before developing a new type of submarine. The performance of this new 'Mackerel'-class submarine is only stronger than that of the Seawolf 1 submarine, and there is still a slight gap between it and the Seawolf 2 submarine, not to mention the latest Seawolf 3 submarine.

For the escort destroyers of the Chinese Empire, which are equipped with new sonars, radars, and submarine-launched rockets, it is a piece of cake to find and destroy them, not to mention that due to Fang Xiaoyu's foresight back then, airfields have been built on all the islands occupied by the Chinese Empire as long as there are conditions, and with the help of those water patrol planes that also serve as anti-submarine aircraft, these submarines can be regarded as bad luck.

"The merchant ships of the NATO allies were found, estimated at a displacement of more than 30,000 tons." The co-captain, who was operating the periscope, excitedly reported that this was the first target they had discovered in the three days they had been out at sea.

"Search the neighborhood to see if there are any escort warships." The captain suppressed the excitement in his heart and asked the deputy captain to take a look at the surroundings first, so as not to be attacked by the destroyers of the Chinese Navy. Since the beginning of the war, in this cat-and-mouse game on and off the sea, the Boston submarine force has suffered considerable losses, and in the face of the advanced sonar system of the Chinese Empire, the Boston submarine has almost nothing to hide.

After experiencing heavy losses, the Boston submarine also found some tricks, and when they found a destroyer of the Chinese Navy nearby, they sank the submarine to the maximum depth, then turned off all the equipment and left it in the water. The Boston submarine is small, so it has a good chance of evading sonar detection, so every time it attacks, the Boston submarine makes sure that it is safe.

The co-captain operated the periscope and made a 360-degree observation. "No destroyer was found, this is an unprotected merchant ship." The co-captain reported excitedly.

"Great, attention to the torpedo room, torpedoes number one, two are ready, we attack." As soon as the captain's words fell, the sound of propellers was heard in the sky, and a four-engine seaplane slowly flew in.

"A periscope was found, preliminarily estimated to be a Boston Navy submarine." Radar crews used downward-looking optical devices to discover periscopes on the surface of the sea.
