In the silent, serene night sky, there were large clouds floating, a clear full moon hanging above the clouds, and silver light shining through the occasional gap on the green fields.

In the distant sky, an unnatural mechanical sound gradually became apparent, the same silver-gray, different white-black iron cross, the metal flying machine with huge wings and four large engines dwarfed all the creatures in this world, and the amazing endurance was even more ashamed of the perennial migratory birds.

One, two......

One group, two groups......

When there were more and more silver-gray flying machines, there was only a dull roar in the entire air, and huge black shadows were moving rapidly on the rolling clouds, and the powerful air currents carried by them set off "cloud waves......

"Here, another drink! If you don't get drunk, you can't go home! ”

Muffled voices came from the corners of the silent streets, and the two night guards paused slightly, shook their heads and smiled, and continued on their way. Although it was already midnight and the curfew had been ordered since the beginning of the war, there were such drunkards on the streets of Osaka all year round, and as soon as the morning dawned, they would get up and go home, or they would die on the streets and be disposed of as vagrants.

As a bustling city with a history of more than 1,000 years, Osaka has been known as the "City of Water" and "the Kitchen of the World" since ancient times, and has been one of the most important cities in the Kyoto area and the whole of Japan as a transportation hub, commercial center, and industrial center since ancient times.

As the night gets deeper, most of the people who have been busy all day are dreaming. Suddenly, the false calm was shattered by the sound of a terrible air raid siren, and the city was awakened, and millions of citizens were awakened, and people rushed into the streets as fast as they could, rushing towards the nearest air raid station, and everything seemed to be in such order that it had been rehearsed a hundred times.

Soon. The city's ground air defense system was in full swing, the beams of high-power searchlights swept back and forth on the clouds, the anti-aircraft guns around the city and the important facilities were all in a state of readiness, the regular army soldiers in steel helmets and the militia with less equipment also focused their nervous eyes on the sky covered with thick clouds, and even the whistle in the harbor rushed to join in the fun—at this moment, the ships moored in the harbor were busy sailing out to the open sea to take refuge!

"Hit! Beat! Well done, knock down all those mongrel Germans! ”

A few drunken men staggered to the corner of the street to watch the excitement, and they pointed their fingers at the sky without scruples and shouted and cursed. The people around who rushed to the air raid station didn't bother to pay attention to them, and there were always such poor creatures everywhere who couldn't get over their pride.

It has been nearly half a year since the start of the war, not to mention the big cities such as Tokyo and Osaka, and even many small towns have built sufficient anti-aircraft bunkers in accordance with the orders of the Japanese military headquarters, and the citizens have also conducted many anti-aircraft exercises, and everyone has been asked to take refuge in the nearest air raid station within half an hour of the air raid sirens sounding, so as to minimize the losses of the German bombing grounds.

However, the Japanese army's early warning system was not sufficient to sound the alarm 30 minutes in advance. Before the crowd in the streets had dispersed, the sound of artillery began to sound in a dense manner, and after a few seconds. The first aerial bomb also fell from the sky with a whistling sound. The crowd on the street was in a state of panic.

"Don't mess around, run over there! Don't mess around! The militia standing on the street corner directing the crowd shouted anxiously, but not many people cared about his orders. Even if you hear it, you will be overwhelmed by the contradiction between "run" and "don't mess around".

When they saw black dots falling nearby, people subconsciously lowered their heads and bent their waists, but the imaginary huge explosion did not appear, but was replaced by a muffled sound similar to an incendiary bomb, and the damage to the eardrum was definitely not more than 50 meters away. At this time, many people were a little relieved, even Germany, which is good at military industry, may inevitably create a "stink bomb"!

However, what happened next left the citizens of Osaka, who had not yet entered the air defense station, stunned. Large puffs of yellowish-white gas came out of nowhere, and although the gas moved very slowly, it gradually formed a situation that surrounded the people in all directions on the street.

What's even more terrifying is that once people come into contact with this gas, they will quickly develop symptoms of coughing, sneezing, and tears, and in severe cases, they will fall to the ground due to difficulty breathing. Suddenly, the panic in the streets escalated into chaos, and people searched for their own ways to escape, but the increasing yellow and white gas had enveloped large swathes of the city like a mist, and the people exposed to the streets were quickly cornered......

In an air raid station near the city center. In addition to the elderly, women, and children, there are also many men in the prime of life, although so far the Japanese military department has set up two army divisions with Osaka as a recruiting ground, and it has long been known that the people of Osaka "love peace" have long been known to everyone, and men would rather sell vegetables than join the police, militia, and fire organizations. So at this time, there were probably only so many young men on the streets of Osaka in the whole country.

Outside, the cannon fire became more and more violent, the children hid tightly in their mother's arms, the old people looked a little sad, and the baby's cry was a little disturbing, and it was somewhat surprising that most of the men were chatting as if nothing had happened.

"Hey, isn't this Aoda-kun? How's business going? ”

"Well, thanks to everyone, it's so-so!"

"Huh? Matsumoto-kun, why are you here too? Didn't you say that you were not afraid of the bombs of the Germans? ”

"Alas, I can't sleep anyway, so it's not bad to come here to chat!"

"Hey, I don't know if you have noticed that the momentum of the Germans' bombing today is very weak!"

Humpty Dumpty's words immediately attracted the attention of those around him.

"Seems to be!"

After he said this, everyone also felt that it was very reasonable, because the explosion sound today was not as strong as usual, and the scene of the earth shaking and shaking has not yet appeared.

"Molotov cocktails!" A man sitting in a corner with gold-rimmed glasses spoke in a quiet voice.

"Molotov cocktails? Yes...... I need to go out, I still have a few hundred pounds of cotton in my warehouse......" Another man jumped.

"It's useless to go, it's better to leave it to fate!" The man with glasses in front of him stopped him coldly, after all, the terrible power of the German incendiary bombs was basically heard of by everyone here, and it was not at all that a few people could extinguish with water. - So. The man who was still thinking about saving cotton just now immediately squatted down in frustration with his head in his hands.

"Alas! Damn the Germans, I don't know how many people will be homeless this time! Another older man sighed deeply, in the eyes of their civilians, Japan should never fight a war with a power like Germany, if it was just bullying and bullying countries like China, it was impossible for the other party to threaten Japan itself.

Everyone was still chatting, and a violent coughing sound suddenly came from the direction of the door of the air defense station, and the originally quiet crowd suddenly began to stir from that direction.

"What's going on?" The people inside are still a little confused. And when they saw a small amount of yellow-white gas slowly drifting in from the direction of the door, their thoughts suddenly did not follow.

"Ahem, what is this? It's so uncomfortable! Ahem! ”

Indeed, Lewis gas and mustard gas are mixed together, and the smell of garlic and geraniums is familiar to Japanese chemical experts, who used this poison gas to attack the German capital Berlin more than four months ago, and the feng shui turned around, this time the Japanese themselves.

In order to prevent the heat wave and toxic gases such as carbon dioxide generated by the explosion of bombs and incendiary bombs, the underground bunker air defense station has set up a closed-door gate and an exhaust fan with a simple filter, but the actual number of people accommodating it far exceeds the number of people designed. Plus the air defense evacuation of the urban area has not yet ended. The doors of the air raid station were not completely closed, and the improvised exhaust fans were not enough to withstand the specialized poison gas attack, and it seems that the overconfident Japanese designers did not anticipate a large-scale poison gas attack on their homeland. And time and money also did not allow them to build anti-aircraft bunkers with first-class equipment in supermassive quantities.

As a result, in just a few minutes, the originally safe shelter became a full-fledged gas chamber, and the citizens of Osaka rushed desperately to the outside, but the chaotic scene and limited exit channels made most people lose the opportunity to escape from here, and even those who were lucky enough to escape from the air defense station did not find a real way to escape, because at the end of the German bombing, about half of the Osaka city was filled with terrifying yellow-white gas, and these gases continued to spread to the surrounding area.

Osaka Garrison Headquarters Building.

"What? The Germans dropped thousands of gas bombs on us and created great fear among the population? Yaga! Yaga! ”

The man with his trademark mustache under his nostrils was Major General Mukaiyama, the commander of the Osaka garrison, after hearing the report from his subordinates. Without hesitation, he gave the other party two loud slaps.

This is not because the other party is talking nonsense, but that frightened look makes Xiang Shan feel ashamed, in his thinking, the Imperial Army of Japan should always be calm and calm.

Not only could he not avoid being beaten, but the officer who came to report had to respectfully give a "Hi Yi", that is, "what you taught me a lesson".

Since the garrison headquarters is located near the port area, the speed of the spread of poison gas to this side is very, very slow under the effect of the sea breeze, and this is precisely why. Xiang Shan can still listen to the reports of his subordinates here unharmed.

However, some people just like to do things that don't know whether they live or die, and this Major General Xiang Shan is such a person.

"I'm going to see how terrible the Germans are with gas bombs!"

"But General, it is said that poison gas bombs are deadly......"

The officer shuddered at persuasion, and needless to say, his attitude was exchanged for two resounding slaps.

"Stupid! Idiot! Poison gas is not always fatal, and as the commander of the Osaka Garrison District, once there are heavy casualties among the citizens, what face do I have to live, huh? Xiang Shan took off his saber from the hanger and ordered: "All the city's garrison forces are dispatched, and you must do your best to treat the injured citizens!" Also, call the experts at the Osaka Chemical Research Institute and ask what antidote is needed to deal with this poison gas! ”

"Antidote?" The officer hesitated for a moment, thinking of Xiang Shan's violent temper, and hurriedly agreed:

"Hi Yi!"

"Now, let's go to the city and put on a gas mask!"

Walking towards the gate of the mountain chief's swift meteor, although it was a matter of duty, it was still a bit inappropriate to venture into the area covered by poison gas before getting expert advice, in fact, both Lewis gas and mustard gas have strong penetrating power, and mustard gas can penetrate skin, cloth, leather, and erasers.

Although he was mentally prepared, when Major General Mukaiyama arrived in Osaka city wearing a gas mask and riding in a car, the tragic scene on the streets still stunned the battle-hardened general, and some of the people in his entourage who were less resistant could not help but vomit. Although nearly an hour had passed since the end of the German air raid, the yellow and white fog still did not dissipate, and there were ordinary citizens everywhere in sight. Under the headlights, many of the deceased still had extremely hideous expressions on their faces, which showed the great pain they had suffered before the temporary period. (Mustard gas persists for 4 to 24 hours in open areas in summer, 3 to 5 days in forests and cities, and longer in spring, autumn and winter).

Xiang Shan ordered the driver to continue driving forward with a heavy heart, the corpses on the street were only a small part of the victims, and the mortality rate of mustard gas and Lewis gas mixture was as high as three percent at this concentration, which means that every three corpses here correspond to 97 people who are still alive but are very likely to leave permanent scars. Due to the large number of injured people, most of whom have not had time to be transported to hospitals outside the gas-covered areas, many ambulance workers on the streets are still wearing the most rudimentary protective gear, and the actual casualty rate is rising due to the lack of effective treatment for chemical weapons. Behind the rubber gas mask, Mukaiyama's face was snow-white, he didn't know how many Osaka citizens would die in the end, and he didn't know if Osaka would collapse because of this, but it was certain that his military career had come to an end, and even if the emperor and the military department did not pursue it, he would have no face to live in the world.

On the same night, the Japanese residents of several other cities bombed by German bombers were much luckier, because this time the Germans had prepared only 1,600 tons of chemical bombs and most of them were still in Osaka, while Nagoya and Kawasaki were only attacked by sporadic poison gas bombs, while the German bombers flying to Tokyo had more than 300 bombs, but all of them dropped conventional high-explosive and incendiary bombs.
