Phosgene and mustard mixed gas, the former is a suffocating poisonous gas, which exerts its effect by acting on human respiratory tissues such as trachea and lungs, and is a chemical weapon with fast effect, high lethality, and short residence time, and a very small amount can cause the death of a person without protective equipment; The latter belongs to erosive poisonous gas, which invades the human body through the respiratory tract and exposed skin, destroys body tissue cells, and makes the skin erosive and necrotic, which is relatively less lethal, but has a strong latent and long-term nature, and can also lead to death when the respiratory tract is poisoned or the whole body is severely poisoned!

The old man, whose hair on the top of his head had long since faded and only had a few silver hairs left on his temples, said as he wrote the chemical structure of uppercase and lowercase letters and numbers on the blackboard.

Of course, Chen Tian is no stranger to the most basic chemical symbols, but when they are connected into simple or complex structures by short wires, he can only be at a loss, not to mention the senior generals behind him who don't know much about chemistry!

The old man quickly wrote down a row of chemical structures, pointed to them and explained them one by one:

"This is the main chemical structure of phosgene, its terrible thing is that the effective lethal concentration is only 1/50,000, from the perspective of the effect, when people inhale phosgene, there is only a slight irritation in the throat, and it will disappear later, but in the next one to four days, the human respiratory and circulatory system will fail rapidly, so that with a yawn, the heartbeat will immediately rise to 140 times per minute, and finally a large amount of body fluids containing protein flow out of the mouth, and a life!"

"This is the main chemical structure of mustard gas, after the explosion of mustard gas ammunition. Liquid, fog and vapor states exist at the same time, and can remain toxic for a few hours to 48 hours in the open in the summer and for several days in the winter! Mustard gas does not look as terrible as phosgene, with a fatality rate of only about three percent, but the poisoned person must endure the huge ** and mental torture it brings, which will cause the human skin to fall off in pieces, and then all the hair will fall off, with the disappearance of the epidermis. Mustard gas enters the internal organs of people in a short period of time! We have dissected many poisoned cattle and sheep in the experiment, and found that almost all of their internal organs have changed shape, and the outer membrane of many organs is completely detached from the organs themselves! ”

"This is the main chemical structure of Lewis gas, which itself is also a highly toxic gas, but when used alone, it cannot meet the operational requirements due to diffusion ability, water solubility and other reasons. But it is a good pair of mustard gas in front of it, and their mixed gas has both the persistence of mustard gas and the characteristics of Lewy gas with rapid action and strong toxicity, and it is also the most chemical gas produced in China! ”

"In fact, these chemicals, especially phosgene and mustard gas, are neither cumbersome nor expensive to manufacture, and some ordinary chemical plants can produce them, while our current daily output has reached the expected level, as long as we maintain a steady stream of raw materials and capital investment, we can even increase it to this extent!"

After the old man finished speaking, he looked back at everyone, but the generals with the golden light on their shoulders were collectively silent at this time, this situation the old man had encountered more than once in the previous class. So he didn't show a disappointed expression on his face, but asked:

"Do you have any questions? What about their nature, or whatever? ”

Before Chen Tian spoke, the generals still didn't ask questions, because some of the questions had been explained very clearly by the old man, and some were confidential questions that some people already knew but couldn't say casually, and some people didn't know but didn't dare to ask casually.

"Uh...... Dr. Haber, thank you very much for the introduction, I think you all know a lot about these two types of chemical weapons! In fact, what we want to know more is how well they work in real combat...... We believe they won't perform worse than we expected! ”

"Yes. Your Majesty! Fritz Haber, the best chemist in Germany and the world at this time, a Jew loyal to the German state, director of the Royal Wilhelm Institute of Physical Chemistry and Electrochemistry, director of the Royal Chemical Arsenal and royal chief chemical adviser, was also the technical leader of this huge "Green Mist Project". Since the beginning of the program, he has traveled to the Far East many times, personally supervising and guiding the Air Force in using chemical bombs for bombing, and studying the actual effects of these bombs on the basis of pilots' observations, photographs, and reports from ground spies.

"From the first half of this year. We have systematically dropped chemical bombs on the Japanese mainland for strategic bombing, targeting coastal cities, commercial cities, industrial cities, and transportation hubs in Honshu, Kyushu, and Shikoku, and according to our observations and statistics through various means, three large-scale repeated bombing is enough to paralyze a large inland city for more than two months, and the same amount of bombing can make a medium-sized inland city unable to recover for several years. And to get a coastal city to the above state, it only takes one or two more repeated bombings! ”

"The destruction of cities by chemical bombs is most obvious, and the actual terrible destructive power of small towns and farmland of the enemy, just a 500-pound mustard road mixture bomb can put most of the residents of a town of 1,000 people in a hospital, and according to our years of research, mustard gas can poison people by contaminating soil, water, food and other items in addition to directly causing poisoning of humans and animals! Taking the soil as an example, after the invasion of mustard gas, it will enter the corresponding active period and dormant period with the temperature of the disease, and people may have nothing to do when they walk through the dormant period, but in spring and summer, it is very likely to be poisoned when they walk through again, and it can also be difficult to react with other substances, and can block an area for a long time! Therefore, long-term chemical bombing not only killed and injured a large number of enemy production, but also seriously weakened the enemy's military industry, general industry, agriculture and transportation industry. ”

Despite all the special considerations, Dr. Haber does not directly quote the numbers to corroborate this, but his last sentence is obviously very graphic and very weighty.

"I can add some information to that here!"

Chen Tian turned his gaze from Dr. Haber to the generals, they are not many in number, but they can be said to be the German military leaders in the Far East - Rundstead and Manstein of the army are both senior generals with both qualifications and abilities, Hippert and Dönitz of the navy are the two pillars of the German navy, and Walter Waffel of the air force, although the rank is not high, has served as Zeckert's deputy for many years, and has assumed the heavy responsibility of chief of the general staff of the Luftwaffe, Now he personally went to the Far East to command Germany's strategic bomber forces.

In addition to the above, the rest of the generals are also key figures in the Far East Cluster Command, the Navy's Pacific Cluster Command and the Air Force, and each of them is qualified to listen to Chentian's introduction below:

"So far, our army has dropped chemical bombs on a total of 44 cities in the Japanese archipelago, and the Japanese cities that have fallen into a state of complete paralysis include Osaka, Kobe, Nagoya, Yokohama, and Kashima, and the cities of Kishiwada, Hiroshima, Onomichi, Kochi, Fukuoka, and Otsu that have been seriously wounded, and it is conservatively estimated that more than 200,000 Japanese soldiers and civilians have died in our bombing, and countless more have been wounded! Now we must repay the damage caused by the poison gas released by the Japanese in our country, and we must repay them tenfold or hundredfold, and we must let all the people of the world know that the dignity of the Germans is inviolable! ”

Chen Tian's last sentence also filled every German present with a sense of national pride, and the generals invariably made their posture more imposing.

"Doctor, tell us about our tactical chemical bombardment in Okinawa! Everyone here has the power to decide the life and death of thousands of soldiers, so they should know more about this situation, on the one hand, to avoid accidental injuries to our soldiers, and on the other hand, they can make good use of these advantages of our army! ”

"Yes, Your Majesty!" Haber highlighted the chemical structure of phosgene on the blackboard with chalk, "We had already begun bombing the island before the Okinawa landing campaign began!" In military terms, this is a tactical bombing using chemical bombs, targeting both medium-sized cities with tens of thousands of people and small towns with hundreds of households! General Waffle should be well aware of these circumstances, so far our bombardment has covered nearly two-thirds of the island's towns, and theoretically phosgene can exert more power in this season, and our aerial photographs also partially prove this, but we cannot draw a final conclusion until the ground forces have first-hand evidence! ”

"Doctor, a question occurred to me!"

Everyone followed the sound and stood up was a small but sharp-eyed general, his hair was very neatly combed, and he wore a dazzling blue medal of the Order of Max on his chest, of course, he was not the only one who had this kind of medal in this room, but he was probably the only one who was younger than him, "Navy darling" Dönitz.

"Our bombing has been going on for more than half a year, will the Japanese have already found an effective antidote or made enough protective equipment?"

In the blink of an eye, his eyes were focused on Dr. Haber.

After pondering for a moment, Haber replied: "This is theoretically possible, but to produce enough antidote and armor for the inhabitants of all places, in my personal opinion, it would be impossible for the Japanese to do it under normal circumstances without three or five years!" Moreover, the first aid process after poisoning is very complicated, so even our troops have to be extremely careful when entering poison gas contaminated areas, and we have a large number of specially trained medical personnel in field hospitals and front-line hospital ships! ”

"As far as I know, our troops have begun to contact the contaminated area today!" Manstein spoke slowly.

Haber gently pushed the glasses on the bridge of his nose, "I know that, but they are basically not in any danger, phosgene dissipates quickly, especially where there is water!" ”
