The sun is shining, the white clouds are surging, and the blue sky is as if it has been washed, and it is intoxicatingly clear. Below, however, the city of Paris is a scene of war-torn devastation: crumbling buildings and crumbling concrete and stone are so dense that there are barely intact buildings in sight. A large number of bloody corpses of German and French officers and soldiers lay in the middle of the battlefield, attracting a large number of stray wild dogs from the city and suburbs to come and eat and tear; Despite the constant sound of gunfire and explosions, these guys did not flinch.

With a telescope in hand, Qingying stood on a towering tower and looked quietly to the west. Known as the capital of the arts, Paris lives up to the grandeur and grandeur of the world's second largest city, and even after three months of war, there are still a large number of buildings left in the sky. The Germans poured countless bombs and artillery fire on it, but they still did not destroy the city and the determination of the French army to resist. There is a world of difference between the stubborn struggle of the French nation at the beginning of the 20th century and its rapid knee bending in 1940: Historically, France, with a total population of only 39.6 million, still did not say half a word of peace to Germany after suffering a huge loss of nearly 1.7 million dead and 4.266 million maimed people; this is a desperate act that can only be made to the opponent after it has already been beaten to the state of madness of the whole people!

At present, the total losses of the French army in the battles of the border, the battle of the Marne, the rush to the sea, and the defense of Paris are less than 1 million, and it is still a long time before they are exhausted. In order to solve the war on the Western Front as much as possible, in addition to depleting as many French troops as possible, the subversive news of the defeat of the British fleet was used to break their confidence in resistance. It is also one of the important ways. In this case. Qingying no longer cares about humane considerations. It's time to unleash the devil in Pandora's box!

"Your Highness, the show is about to begin." A voice with a slight excitement and anticipation sounded in Qingying's ears. Qingying turned her head, and the figure of a middle-aged man suddenly came into view. He was of medium stature, wearing a slightly scruffy dark gray double-breasted coat, and at first glance he looked indistinguishable from those unambitious uncles on the streets of small towns; However, the condensed charm of his gestures, his bright baldness that can reflect light, and his piercing eyes behind round glasses all show his unique charm as a scientific maniac.

Is he Fritz? Haber, born in 1868 in Breslau, Germany, to a Jewish merchant family, was a diligent and intelligent young man. He has an extraordinary passion for the chemical industry. At the age of 19, Haber was awarded a doctorate by the Royal Technical University of Germany, and has been at the forefront of contemporary chemistry ever since. Historically, after the outbreak of World War I, Haber, who had already served as the director of Kaiser Wilhelm's Institute of Electrochemistry, began to develop chlorine, mustard gas and other poisonous gases, and strongly advocated the use of them in the war to win the war.

Under his leadership, the Germans were the first to use poison gas in the Battle of Ypre in April 1915, which opened a Pandora's box containing demons, killing or maiming nearly a million people in the war. A certain Bohemian corporal, who was awarded the Iron Cross of the first class, was also blinded by poison gas for a short time; If the concentration of poison gas had been stronger, the history of the whole world would have been rewritten.

As a result of the first poison gas and the defeat of Germany. Haber's reputation has been trampled on in the histories compiled and propagated by London's elite; So much so that as soon as people mention the name, they associate it with demons that use poison gas. As a matter of fact. Haber was awarded the Nobel Prize in Chemistry in 1918, and the Royal Swedish Academy of Sciences decided to award him such an honor while the Great War was still going on, because he had previously contributed to the creation of a world of goodness, the Haber method of ammonia synthesis.

Since the beginning of the 19th century, with the growth of the world's population, people's demand for nitrogen fertilizer has skyrocketed due to food problems. At that time, all nitrogen fertilizers used in agriculture came from organic by-products, and the yield was very limited. Some visionary chemists of the time pointed out that in order to save future generations from starvation, atmospheric nitrogen fixation was necessary. Haber took on the challenge of researching this almost world-class problem. In 1909, after countless theoretical calculations and the "Haber method", it was finally possible to achieve a steady output of ammonia in the form of nitrogen and hydrogen synthesis, and in the following years, it was completed from the real yàn room to the industrial mass production.

The significance of ammonia synthesis is enormous. It frees human beings from the limitations of natural nitrogen fertilizers, which is equivalent to receiving the supreme grace of God to create zào bread from the air. A small atomic bomb changed the course of World War II; The pure and colorless synthetic ammonia has promoted the development of world agriculture. It is a nuclear weapon that drives agriculture, and its importance cannot be overstated. Since there is ammonia synthesis, the fertilizer can be doubled; Synthetic ammonia is used for fertilizer, wheat yields of 1,300 per acre, farmers are smiling, and Germany's grain production is expected to double in the future.

In addition to agriculture, ammonia also played a crucial role in the promotion of the German arms industry. It allowed the military factories to produce a steady stream of powerful explosives using the nitrogen captured from the air, and the German military factories no longer had to import natural nitrates to Chile. Without the industrial nitrogen fixation achieved by synthetic ammonia, Germany's war plane, which had been blocked from the source of material imports, would collapse on its own after half a year of operation because it could not make the propellants and explosives of various guns and shells!

In recognition of his research in the field of nitrogen fixation and his irreplaceable contributions to the development of world agriculture and German national security, Haber was given the surname of Feng by the German Kaiser after the war, and was named Count Wilhelm, enjoying the same treatment as the German royal family. Every year before the festival, the Kaiser visits the Karlsruhe Institute, where Haber works, to thank Haber for his invention of synthetic ammonia. Of course, this is all a matter of later information, so I will not mention it at this time.

A week earlier, Qing Ying, sensing the heavy casualties inflicted on the Germans under the city of Paris, had proposed to the General Staff that they should break the current stalemate with a "completely new weapon" and thus seize the entire city of Paris. At this time, Haber also wrote to the German government that the army should use a batch of chemical weapons that he had painstakingly built for his homeland against the enemy, so as to end the war, which would kill a large number of Germans every day. The needs of the front-line commanders and the enthusiasm of the scientists in the rear suddenly hit it off. Under Qingying's arrangement, this cargo was quickly transported to the front line in Paris; After receiving simple training, German soldiers threw themselves into the use of this weapon.

"These big round guys are the result of my efforts and that of my team."

Looking in the direction Haber was pointing, Qingying saw a large cylindrical steel pressure vessel with a volume of about 100 liters, which had been loaded by a cart and placed at the street entrance hundreds of meters in front of the house. Several German soldiers were nervously working on the pipeline connection, and the goggles and bloated masks on their heads reminded Qingying of the terrorist appearance in a classic game in the future. After a short time, a flexible special pipeline was stretched by German soldiers from the opening valve of the pressure vessel to a position close to the front of the battlefield; And the soldier in charge of placing the pipeline was also afraid of this guy in his hand, and after completing the fixation, he kept returning to the edge of the steel container for a moment.

"Dr. Fritz, how much gas did you prepare this time?" Qingying's telescope turned and looked at the group of German soldiers who were carefully operating pressure bottles and cans in the streets and alleys, and couldn't help asking.

Haber said with a little regret: "I rushed to make and raised 180 tons of chlorine gas in the research institute overnight, and now all of them are on the front line in Paris. Due to the lack of large-scale industrial production, my team can only produce gas with real equipment, and its production capacity is too limited. In terms of killing effect, these chlorine gases are not ideal toxic gases: people need to inhale a considerable amount of chlorine gas to cause poisoning, and the poisoning effect is not strong. From the perspective of toxicity analysis, dichlorodiethyl sulfide, uh, that is, mustard gas, has a rather ideal killing effect; In 1886 Mr. Meyer completed the synthesis of pure mustard gas, which we can now produce in large quantities in chemical plants. ”

Qingying nodded slightly. He put down the binoculars in front of him and looked up at the sky; White clouds flew in the blue sky, all of them fluttering towards the west. Feeling the forward movement of his clothes, Qingying took a deep breath: Yesterday, according to the forecast of the meteorological department, there would be an easterly wind of no weaker than level 4 in Paris all day today, so he prepared to stop these bottles and cans, and arrived at the pre-determined launch position in the early morning and night. At present, the wind direction in the city of Paris is as expected, which is just right for this kind of compression bottle release method that is strictly dependent on the direction and strength of the wind; The German units deployed in the front line for street fighting have all been quietly withdrawn at night, and now is the time for these gases to do their job!

"Bang!" When Qingying's pocket watch pointed to 8:45, a flare rose into the air from the rear of the German army. German soldiers in gas masks struggled to twist the pressure valve, and a breathtaking sound sounded from the bottle. After a short time, a yellow-green smoke screen suddenly floated up in the ruined city streets, rising to a height of ten meters in the air; Then, under the push of the wind, it drifted leisurely towards the area controlled by the French army.
