"Platoon commander, what's that yellow-green smoke?"

In a building with half-collapsed walls and ruins, Private Enes peeked out of behind the broken window and asked the lieutenant officer next to him with puzzlement. Next to him, more than a dozen red pants also looked inquiring, and after Enes asked about the doubts in their hearts, they all turned their eyes to their superiors.

French Lieutenant Gaston frowned, and his gray-blue eyes looked at the city to the east without blinking. The thick yellow-green smoke rolled and surged, fluttering into the sky more than ten meters high, and under the blowing of the morning breeze, it was getting closer and closer to the direction where he was. He scratched his scalp a little irritably, but he couldn't guess what trick the Germans were playing.

Since the early hours of this morning, there has been an anomaly in the German positions on the opposite side. The intensity of their gunfire was noticeably less than before, so much so that the frontal pressure of his unit was so lightened that each of the lads was given a precious extra nap. And after the sun had risen, the Flying Fortress airships, which represented demons, did not visit Paris in time; The heavy artillery suppression deployed by the Germans outside the city was also sparse and weak, which surprised Lieutenant Gaston, who had been used to being ravaged by heavy artillery bombs all day long. Gaston was completely blinded by the fact that he was completely blind to the yellow-green gas that had never been seen before!

Looking at the thickness and tightness of the smoke, Gaston had a flash of inspiration in his mind, and said in a deep voice: "This is very likely to be a smoke bomb released by the Germans." They want to use these things to hinder our sight. Then he approached us behind the smoke. Thus traverse the central danger zone of the battlefield. Everyone must be in absolute spirit. Be on guard against a possible German surprise attack and be ready for melee combat at any time! The French soldier next to him suddenly lit up and nodded in agreement; They skilfully ran to their respective positions, then broke the bricks in the horns and stretched out their rifles from them. For defensive street fighting, the French soldiers were full of confidence, and they had unearthed countless ideal positions for black guns; These places not only have good visibility and shooting boundaries, but can also be used as perfect defense and concealment by means of guò brick blocks.

Pocket watch ticking. A breeze blows. French soldiers armed with rifles hid in all corners of the buildings, watching nervously at the movements ahead through guò firing ports and other holes in the walls. Gradually, Lieutenant Gaston began to feel that something was wrong, because if the German soldiers were hiding behind the smoke, then there should have been footsteps and tentatively suppressed gunfire anyway, but the whole battlefield was now terrifyingly quiet, only the yellow-green wall of smoke was constantly fluttering and surging towards him.

"Platoon commander, do you smell something, why do I think there is such a pungent smell in this air all of a sudden?" Private Enes covered his nose with his sleeve. Said to Gaston.

Gaston's nose twitched, and sure enough, he felt a spicy and sour breath rush to his nerves. The strong pungent smell caused him to feel dizzy for a short time. Gaston covered his sleeves in front of him and swore and said, "Are these Prussian beasts who deserve to be hanged so bad in their smoke bombs?" One day, I'm going to shove all these bastards into a pepper bucket and make them ......"

Before he could finish speaking, a sour smell ten times stronger than before suddenly surged; Gaston could no longer hold back the tearing pain in his chest, and began to cough violently uncontrollably, only to realize that his voice had become as dry as a broken gong. At the same time, Enes next to him also began to cough heavily, and a large amount of crimson blood foam had already appeared in the thick phlegm that he coughed up!

"These are toxic gases! Everyone, get out! Feeling the sharp pain in his head and lungs, Gaston suddenly understood everything and shouted hoarsely. The French soldiers, who had been smoked to the ground, woke up like a dream, and struggled to break through the door, and the guns in their hands no longer knew where they had thrown them. Chest aches and headaches that had never been more intense than ever before hung over the French soldiers' bodies like nightmares, and the irritating breath that swept through the blast continued to disintegrate their brain nerves. With a burst of "plopping" sounds, several French soldiers could no longer hold on, and staggered to the ground in the process of running towards the rear, and in an instant they were enveloped in the yellow and green smoke that flowed in. The rest of the French officers and soldiers did not have the strength and time to rescue the robes, and the great physical pain and weakness of their limbs made them have to squeeze out their last bit of strength and try their best to escape from the enveloping range of these poisonous gases!

Chlorine is cloudy, like a deadly hell soul hook; Wherever it went, the French officers and men fled in panic in a violent cough and a severe headache. The slightest slow reaction was immediately trapped in the deepest yellow-green mist, and before the gas war was carried out, Haber had already calculated the concentration dose, so that the heavier-than-air gases were released from the compressed gas tank and stretched just enough to cover the buildings of Paris. In this way, even the French snipers with black guns on the roof of the building could not survive in front of this blasting chlorine wall. In fact, these snipers were even more traumatized than the French soldiers who defended in the middle and lower floors, as they had to brave the poison gas to run down the building to escape, which undoubtedly greatly increased their exposure to the poison gas.

And the French soldiers who were running around hiding in the sewers were even more wiped out because of this. Due to the fact that chlorine is heavier than air, it sinks and falls directly after encountering the sewer mouth, and the French soldiers who are caught off guard immediately fall down after smelling the smoke. And although there is no east wind on the surface of the sewer, and the chlorine gas spreads quite slowly after sinking, the chlorine gas on the ground is constantly moving forward under the impetus of the wind! Every time a chlorine smoke screen sweeps over a sewer outlet, a large amount of chlorine gas settles and fills the entire vicinity of the drain. When the French soldiers in the sewers were about to go out in another place, the poison gas that had been waiting for the exit immediately dealt them a fatal blow.

An hour later, all the 180 tons of chlorine prepared by the Germans had been discharged. From the tower where Qingying is located, the entire northern city of Paris is plunged into a cloud of smoke dominated by yellow-green; The wind did not stop, and these demons, which were enough to kill people, swept towards the city area controlled by the French army.

In fact, chlorine gas is only at the bottom of the professional poison gas because of its water-soluble properties, French soldiers only need to soak their sleeves in a kettle and then cover their noses and mouths, they can resist the attack of chlorine gas on a certain distance, and escape from ascension with moderate or even only mild poisoning injuries. However, the French officers and soldiers had never seen this method of attack, and they had already entered a state of panic, which made up for the shortcomings of chlorine gas that was not very toxic in a certain way. As time went on, more than 10,000 French officers and soldiers were smoked with splitting headaches, their chests and lungs were on fire, and after escaping the area of effect of the poisonous gas with all their strength to feed, they staggered directly to the rear hospital, and called out the devil in a hoarse voice in a completely dry and hoarse throat. About 1,000 people in Morocco were consumed by chlorine gas, becoming the first martyrs of chemical warfare in human history.

If it had been placed in the past, this inhumane means of using biological and chemical weapons would definitely make Qingying's heart like a boulder, depressed and stagnant; However, it has been 20 years since he traveled to this era, and the value of thinking has undergone a fundamental change compared to before. In the current era of social Darwinism and the fact that truth is within the reach of cannons, only "shining armor" and "iron fist wrapped in steel armor" are the only way to talk to the enemy. Both warring sides are sparing no effort to develop new weapons in order to kill each other; Any kindness to the enemy is cruelty to oneself, and only by defeating the opponent first can there be room to talk about other things. Historically, the London-speaking elites who denounced Germany's poisonous gas in the name of human rights and justice seem to have forgotten that they themselves released poison gas on the Allies in the Great War!

After noon, the poisonous gas that permeated the city of Paris gradually dispersed with the wind. Qing Ying wasted no time in giving the order to attack, and the German officers and soldiers began to slowly advance towards an area they had never set foot in before. This time the gas operation was extremely effective, and almost all of the French defenders who had been stationed in the area were gassed; German soldiers with improvised wipes on their mouths and noses advanced at unprecedented speed, soon capturing buildings and blocks. The Germans used the method of completely destroying or sealing the sewers they encountered to ensure complete German control of the area.

By nightfall, the Germans had completely occupied the northern part of Paris, which had been swept by the poisonous gases during the day, at a small cost of more than 500 casualties. The German front-line troops were so shocked by the speed with which they advanced that the rear command wondered if the casualties were underreported by a zero. When the detailed battle report and a photograph of the Eiffel Tower were sent back, Moltke finally understood what kind of victory he had won today in the street battle in Paris, which had been difficult to conquer for a long time. The German government also issued another statement to the French government later in the evening, saying that Berlin had mastered a "weapon of great power"; If France does not surrender, the entire city of Paris, including the Eiffel Tower, the Arc de Triomphe, and the Louvre, will be reduced to ashes in the face of the Prussian wrath. (To be continued......)
