The Fusang soldiers at the front didn't know what was going on, they rubbed their eyes with their hands, it was too hot and couldn't stand it.

"Ah, my eyes!"

"Ahhh!!h

Many Fuso soldiers fell to the ground and rubbed their eyes frantically, and some even took out the water bottle they carried with them to clean their eyes, but the more they cleaned, the more painful it became.

In addition to their eyes, they also felt a choking nose and a little burning pain when breathing, which was very uncomfortable.

This phenomenon spread rapidly among the Fuso army, and as if it was contagious, more and more soldiers showed this phenomenon, and even lost their guns, and they could not fight at all.

"Quick, don't smell these smells, cover your mouth and nose with things, don't open your eyes!" The officers began to react, although they also had a bad situation, but knowing that these unusual smells could not be smelled, where did the mustard smell come from on the battlefield?

"Doctors, doctors, hurry up!"

The officers who were recruited shouted loudly for the military doctor, and some ran to the military doctor directly regardless of the order, and they couldn't stand it anymore.

When this first happened, the military doctors had already rushed there to save them, and many of the military doctors are now in this situation. A large number of soldiers had a burning sensation in their eyes and noses, and the military doctors also guessed that they were poisoned, otherwise they would not have the same symptoms on a large scale.

"It's mustard gas, it must be mustard gas, colorless mustard gas, the people of China are using this poison gas!" The well-informed military doctor finally confirmed with his rich experience that it was mustard gas, which was discovered as early as the last century, and Fuso was also studying this mustard gas, and some military doctors were fortunate enough to learn a little, but did not know how to solve it.

"Your Royal Highness, you hurry up and retreat, the hateful people of China have actually made mustard gas into weapons, and the iron cans dropped by those planes are mustard gas, you must retreat for your safety!" A military doctor nervously shouted at the Prince.

At this time, the wind direction was blowing towards the Fuso position, so the spread of mustard gas was rapidly expanding, but it had not yet reached the rear headquarters, and the prince did not appear to have any problems.

"What is mustard gas? Explain to me clearly, and what's wrong with the soldiers in front? ”

Prince Fushimi Miya's Sadachi didn't know what mustard gas was, and he also saw the situation of the soldiers in front of him, it was too unusual, and the entire Fuso army would be finished if it went on like this.

The military doctor wiped his sweat and explained: "Mustard gas is a colorless erosive poison, the poisoning effect is very strong, once poisoned, it will cause all kinds of poisoning throughout the body, guide zhì lose the ability to normal activities, and even cause death!" Now we are in the windward area, the poisonous gas is blowing towards our army, and the scope of the wave is rapidly expanding, please evacuate quickly! ”

After listening to this, Prince Fushimiya's face changed instantly, he didn't expect that the army of Shina would be so miserable and make poisonous gas, and use it on his own soldiers, it was simply shameless!

"Is there any way to prevent it, is there any?" Prince Fushimi Miya's shoulder shook vigorously as he hugged the military doctor's shoulder, his eyes full of hope.

"I'm sorry Your Highness, we don't have a good way at the moment, we can't do anything, woo woo !!" The medic began to cry as he spoke.

Prince Fushimi Miyaya Sada'i glanced at the officer next to him who was about to move, gritted his teeth and said: "I believe that the Shina army will attack soon, we must block them, and they will not be allowed to break through the defense line even if they die, and no one is allowed to retreat without my order!" ”

The prince thought that if he retreated now, he would definitely be pursued by the Shina army, and the military defense he had so painstakingly built would be useless, and Seoul would be completely exposed to the attack of the Shina army, which was their base camp, and if the base camp was attacked or even breached, it would be a heavy blow to the entire Fuso army.

"Your Highness, we still have a few sets of gas masks there, I'll go get them for you!" The military doctor ran away quickly, they did have a few gas masks, the effect of anti-poison was not very good, but Liao was better than nothing.

"Your Highness retreats immediately, those poisonous gases are too powerful, the poisoned soldiers have lost the ability to fight, wait until you find out these poisonous gases and then continue to make plans, please think twice!" Kawamura Keiaki persuaded.

Oshima Hisunao said: "I don't think retreating will solve the problem, the Shina army can launch a second poison gas attack, we must hold here, there are reinforcements coming from the south, as long as I hold on, I will definitely be able to block the attack of the Shina army!" ”

"Look, the Shina plane is here again, dropping down a kind of iron canister with greenish-yellow gas, and the gas is drifting towards us!"

Prince Fushimi Miyaya Sadachi and others hurriedly looked through the telescope, only to see dozens of fire dragon bombers dropping hundreds of iron cans, a large amount of green-yellow gas floating out of those iron cans, and then quickly forming a green-yellow cloud towards them.

These greenish-yellow clouds rolled down the ground and fell into the trenches, and when they floated in front of the Fuso soldiers, the Fuso soldiers began to suffocate, gasping in pain, and a large number of soldiers fell, their eyes, noses, and throats burned as if they were burned by the acid, and some were even suffocated to death.

The surviving Fuso soldiers grabbed their throats and ran blindly in all directions, and even the officers were too busy to take care of themselves, and all the Fuso soldiers who were affected were in chaos.

"What kind of poison gas are those, ordering the troops behind to retreat five kilometers, and the military doctor will do his best to treat the poisoned soldiers!" The prince was frightened by these gas attacks, but he did not give up, but only let the army behind him retreat a few kilometers, he did not believe that the gas would spread so far.

The Fuso defense line was in disarray, almost completely collapsing, and the soldiers behind were also frantically retreating.

"Boom ......"

The artillery of the Chinese army wore rubber gas masks on their heads and fired shells, and hundreds of shells flew towards the Fusang position, and instantly fell there and exploded.

To the horror of the Fuso soldiers, the shells exploded into clouds of greenish-yellow gas, or some of the shells were very weak. Some gases are colorless, while others are colored, so you will see a large number of low-power shells exploding.

The artillery fire of the Chinese army was incessant, and artillery shells continued to fall on the positions of the Fusang army in batches, and the colored gas quickly enveloped most of the positions.

"Ahem, ahem, ahem......"

Countless Fuso soldiers grabbed their throats and coughed, their faces flushed and knelt on the ground very uncomfortably, even the soldiers who were retreating behind them also appeared.

"Shoot back, kill the artillery of the Chi Na people, we can't let them continue to fire these shells carrying poison gas!" Hisunao Oshima shouted for the artillery to fire back and stop the Chinese army from continuing to fire gas bombs.

"Boom ......"

"Ahhh!!h

The poisonous gas had already enveloped the Fuso artillery, and the Fuso artillery endured the physical discomfort and fired the shell, but after the shell was fired, the air around the cannon suddenly burned, burning the Fuso artillery.

It turned out that the poisonous gas they were shrouded in contained a large amount of mustard gas, which burned at high temperatures, and then generated other toxic gases, which were mixed with various poisonous gases, and the lethality instantly increased. Encountering this situation, the Fuso artillerymen did not dare to continue firing shells, grabbed their throats and covered their noses and ran back.

Prince Fushimi Miya's Sadaai suddenly felt a burning sensation in his eyes, he knew that the poison gas had been involved here, and then frantically shouted to retreat.

The Fuso army retreated frantically, and even the weapons and ammunition were gone, and the officer's words had no effect, and no matter how powerful the warriors could not bear it in this situation where life was worse than death, so the retreat of the prince detonated the frenzy of fleeing from here.

But the Chinese army did not let them go, and the fire dragon squad in the sky chased them and threw gas canisters and gas bombs, and the fleeing Fusang soldiers were also poisoned.

The defense line of the Fuso army completely collapsed under the blow of poison gas, most of which was a direct effect of poison gas, and the other lines of defense that were not attacked by poison gas also retreated in fear. The defense line of the Fusang army was too long, and it was impossible for the Chinese army to launch a full-scale poison gas war, so it only attacked their main position.

The Chinese army did not advance because of the collapse of the defense line of the Fusang army, it still did not move there, the dissipation of the poison gas was very long, and the scale was so large that it would initially disperse after a day, and the Chinese army did not dare to enter even if it had gas masks.

The Fuso army soon fled the gas-stricken area, far more than five kilometres away, until they could no longer smell the choking mustard and could not see the colored gases.

In the end, there were only more than 100,000 Fuso soldiers who escaped, and all the rest were left there, either dead, or wandering around and disoriented, or so uncomfortable that they lost the ability to move. Nearly half of the Fuso soldiers who escaped had various adverse reactions, and Prince Fushiminomiya Sada's eyes were swollen and couldn't be opened, and tears kept flowing down.

Most of the supplies, weapons and ammunition of the Fuso army were left there, and they simply did not have time to withdraw all these things, so the losses were very severe.

In the Prime Minister's Mansion of Dongjing, Shigenobu Okuma sat on his chair with blank eyes, and muttered: "It's over, the army is over, I'm a sinner of the empire!" ”

The Shina people made mustard gas and other poisonous gases into weapons and put them on the battlefield, and Fuso's main army lost half of it, and most of the rest lost the ability to fight, and the materials, weapons and ammunition were almost lost.

What frustrated him even more was that he didn't know how many poison gas weapons there were in China, and if Cheorwon and Pyeongkang also appeared, then their decisive battle in Korea would be a complete failure, and there would be no chance of redemption at all.

The loss of the main army of Fuso completely reversed the situation of the Korean War, the scale of victory fell to the Chinese army, and the Fuso army moved to the defensive stage.
