In the Vladivostok battle command, after Li Guodong threw out the special term...the weapon of mass destruction, and a brief explanation of this term, the commander of the Second Front Army Duan Qirui and the commander of the Third Front Army Liang Huadian were stunned on the spot.

Nuclear weapons, chemical weapons and biological weapons are simply unheard of for Duan Qirui and Liang Huadian.

After a long time, Duan Qirui woke up first and asked, "There are such weapons in the world?"

Li Guodong smiled and said: "Since we have just started in technology and knowledge reserves, many projects are still in the most primitive stage of exploration, but chemical weapons can be put into actual combat."

Liang Huadian asked: "What do you mean by chemical weapons?"

Li Guodong said: "It's poisonous gas!"

Regarding poison gas bombs, Duan Qirui and Liang Huadian can guess that they are inseparable. Ancient military strategists often used poison smoke near the enemy, poisoned in the water, etc., but in ancient times, the equipment was very primitive, and in modern times, it could be upgraded to poison gas bombs, which is not a big fuss.

Duan Qirui asked: "How about lethality?"

Li Guodong explained: "Our poison gas was only one kind of chlorine gas a few days ago, and the method of use was not much more advanced than that of the ancients. We rely on wind to blow poison gas to the enemy's positions. The only advantage we have over the ancients is that we have a large-scale industrial chlorine production base, and the lethality of chlorine gas is also very terrifying. The eyes and skin will be burned. Inhaling a mouthful of chlorine will cause severe blood coughing and difficulty breathing in a short period of time. Inhaling more than three mouthfuls will undoubtedly die."

Duan Qirui and Liang Huadian looked at each other and looked at Li Guodong's surface rubber. The lethality of chlorine was very terrifying.

Liang Huadian asked, "I wonder how much Lord Li brings? Is it enough?"

Li Guodong smiled and said, "Commander Liang is worried that the production process of thousands of companies in the empire requires chlorine gas. The Empire's production and reserves in chlorine gas are huge. If it is fully released, people and animals will be free within a radius of 500 kilometers. The amount of chlorine gas I brought is enough to poison the enemies in the fortress more than five times, so the two commanders don't have to worry about whether it is enough, it's just a question of whether you dare to use it."

Lianghua Palace snorted and said, "What are you afraid of? War is going to be the best!"

Li Guodong snorted coldly: "Don't blame me for not reminding you that using poison gas to fight should not let international public opinion know, otherwise the empire will fall into a serious diplomatic vortex. If the imperial government cannot withstand the pressure, it may find a scapegoat to be sent to the military court for trial. I will definitely not admit it, so the two commanders must be mentally prepared."

Liang Huadian and Duan Qirui suddenly stared at Li Guodong and smiled and said, "It's useless to glare at me. My boat hit a reef on the sea. Ten thousand bottles of chlorine on the crew abandoned the boat sank into the sea. The two commanders thought what was this explanation?"

Lianghua Palace suddenly fell down, and Duan Qirui suddenly smiled and said, "These ten thousand bottles of chlorine were picked up by us. They were accidentally blown up by the enemy as an ammunition depot. That's all."

Li Guodong was stunned at first, then laughed and said, "Is Commander Duan a fellow member of this?"

Duan Qirui smiled and said, "Everyone!"

Li Guodong immediately stood up and asked, "Then is that what's up?"

Duan Qirui and Lianghuadian also stood up, and Duan Qirui smiled and said, "It's just that, the credit must be the ones that Lord Li will definitely be."

Li Guodong smiled slightly and said, "Only you and I know about this matter. Both the credit and responsibility have nothing to do with me. Both the two commanders. I just reminded you that the confidentiality work must be done." Duan Qirui and Liang Huadian looked at each other and gritted their teeth to agree. Three days afterwards, Li Guodong sent someone to secretly transport 10,000 bottles of chlorine gas to the front line in the name of artillery shells, and sent a professional anti-biochemical force to keep and guard it.

Vladivostok is located at the southern end of the Amur Peninsula on the Pacific coast of Muravyov, facing the Japanese Sea. The city is surrounded by mountains.

The north of Vladivostok is a highland, bordering Ussuri Bay, Greater Peter Bay and Amur Bay respectively in the east, south and west respectively. The city and port area are located along the coast of Golden Horn Bay at the top of the Amur Peninsula. Golden Horn Bay extends from southwest to northeast and is about 7 kilometers long. The south side of Golden Horn Bay is separated from the East Bosphorus Strait, and there is a Russian island as a natural barrier. The bay is surrounded by low mountains and surrounded by hills. The situation is almost as important as the most important base of the Tsarist Russian Empire in the Pacific Ocean. Vladivostok (Vladivostok) has become one of the five most solid coastal fortresses in the world since 1895.

In 1877, Colonel P.F. Winterberg, commander of the East Siberian Military Region, began to plan for the construction of fortifications in this important port in the Far East, and his design was handed over to Colonel V.P. S., to be responsible for the implementation. A year later, the initial coastal defense project was completed. Since then, the first commander of the fortress, K.S., Chernoknikov, strengthened the coastal artillery position and built the first coastal permanent fortification in the early 1980s. Before and after the Sino-Japanese War, the engineering corps

Colonel K.i and Vilicchiko designed a systematic land defense fortification plan. Based on this plan, Colonel Karkovsky and S.F.Chiri began to build several major fortresses in the fortress: Fortress No. 1, 2, 3, 4, 5 faceted fortresses, and three glasses, connected by trenches protected by xiong walls. In addition, "Russian fortress" and slogan fortresses were built in the Sikhot Mountains and the Agathelid Peninsula respectively. These fortifications were quite similar to the Lushunkou fortress built at the same time.

After the First Sino-Russian War, the Supreme Ministry of Russia formulated a plan to expand the Vladivostok fortress, and built an Eastern fortress that could never be captured to make the Russian army invincible. In 1896, the fortress upgrade plan proposed by General A.P.Digunande of the Engineer Army was approved by Major General A.P.Shaoxin, Commander of the Vladivostok Fortress Engineer.

In the following years, fortresses No. 1-7 and A, E, Z and Z fortresses were built on the south bank of the Suifen River Basin from Ussurisk (Shuangchengzi) to the Amursky Gulf, collectively known as the Second River Fortress. Fortresses 9-12 and coastal fortresses were built on the south and east coasts of the Russian Island, collectively known as the Amur Peninsula Fortress. Anti-landing barriers were set up around the Amur Peninsula Fortress, absorbing all the achievements of military engineering and technology at that time, including many well-set bunkers and underground passages.

In 1900, the conflicts and frictions between the Chinese Empire and the Tsarist Russian Empire intensified. General Alekseyev, commander-in-chief of the Far East, approved the third phase of the expansion project, and established a new coastal defense system and fortress upgrade project in and around Vladivostok, including a solid coastal fortress No. 223 built on the Russian Island, equipped with five 280mm and 10 240mm coastal artillery, collectively known as the Russian Island Fortress.

The Chrysin Peninsula Fortress is also built on the opposite side of the Russian island fortress Ussuri Bay, including 240 mm and 152 mm railway guns, as a coastal defense system to cover the possibility of the enemy capturing Vladivostok from the sea.

In order to defend the city center, General Alekseyev allocated special funds to build the Lujiawaya Fortress on the northeast mountain of Jinjiao Bay. In the deep behind the second river, the first river fortress was repaired near the city center, so that the entire Vladivostok fortress was connected from the outside to the inside.

After more than ten days of attack, the Chinese Emperor's team was still blocked under the fierce attack of the huge artillery fire of the three navy, army and air forces. The second river fortress, Lujiawaya fortress, the Lujiawaya fortress, Qiulijin fortress and the Russian island fortress, outside the Amur Peninsula fortress and the first river fortress, was generally not hindered, and continued to provide troops, ammunition and food supplies to the outer fortress.

Faced with this situation, if you want to take over the entire Vladivostok, you will definitely cause a large number of casualties and material consumption of the Second Front Army and the Third Front Army of the Chinese Empire.

In the command center, Duan Qirui and Liang Hua Hall were staring blankly at the Vladivostok fortress on the sand table. The sand table was simulated in a complete manner according to proportions. Although it was just a sand table simulation, the powerful aura of Vladivostok fortress still showed no doubt.

"Really decided to do this?"

"The most effective way to end the battle is to be the general. Yesterday I used a bottle of chlorine to experiment on several wild deer, and the effect was very obvious."

"The Vladivostok is too strong. Judging from the current casualties of our army, this is our way to reduce casualties and take the Vladivostok fortress as soon as possible, and it is worth a try."

"The weather is cold, and the soldiers are working very hard in the ice and snow. Russian reinforcements are coming continuously, and the brothers of the First Front are buying us time. In this case, the sooner they take Vladivostok, the more beneficial it is for us, and the same is true for the Russian army."

"You can't let your brothers sacrifice any more, just do it!"

Duan Qirui and Liang Huadian analyzed each other one by one, and finally made up their minds to use extreme plans, summoned a few confidant staff officers and military officers to discuss the matter, and discussed the plan to launch a gas attack on the Vladivostok fortress.

"As the saying goes, war is all about victory, so please give orders!"

Although the officers were amazed at the battle of poison gas, they thought that the imperial emperor was about to come to the front line of Vladivostok, and for the honor of soldiers, they all supported the adoption of extreme tactics against the enemy.

Seeing that everyone agreed, Duan Qirui and Liang Huadian no longer hesitated and emphasized various confidentiality work, they immediately took action.

On February 5, 1902, the first chemical poison gas war broke out in modern history.

After nine o'clock on the night of the 5th, the Second River Fortress, located in the west north of the north of the Vladivostok Fortress defense system, the Second Front continued to bombard violently as usual, but the ground attack troops retreated, and as soon as they retreated, the artillery stopped soon.

When the Russian army saw the Chinese Emperor retreating, they were very happy. The long-term attack caused countless casualties and injuries to the Russian army. They were so nervous that they were relaxed that they were sleepy and they were dozing off on the spot.

Originally, at minus 50 or 60 degrees below night, they would definitely be frozen to death if they doze off like this, but their fortifications were bombarded by shells for a long time and were barbecued by gasoline bombs. The cold cement and bricks had long become as warm as a hot kang, so the Russian army was not worried about being frozen to death.

The exhausted Russian soldiers dozed off and soon fell asleep. Only the alert sentry was rubbing their hands in the cold wind and blew coldly.

In the middle of the night, two kilometers away from the Second River Fortress, two thousand chlorine cylinders were neatly arranged in several rows, extending a five-kilometer-long front line, opposite to the Russian army's second river fortification. A group of people wearing gas masks and wearing white clothes and wearing rice dumplings were opening the doors of chlorine cylinders.

Amid the hissing sound, a large amount of toxic chlorine gas was released into the air. The north wind was not in a hurry, and it just happened to blow the poison gas from north to south to the Vladivostok fortress.

Soon, the yellow and green poison gas crossed the walls, the trenches, and spread in the fortifications. The sentry kept coughing after smelling the poison gas, and their eyes burned, thinking it was caused by gunpowder smoke and they didn't care, but soon the poison gas caused a sharp edema in the respiratory tract, which suffocated the sentry to the end.

The same was true for the Russian soldiers in their sleep. They woke up suddenly when they felt suffocation, but it was too late and they all tied their necks tightly and died in fear.

The poison gas was the first to rush to the No. 4 Dazhi, which was about to be cold in the upper river, and then the entire No. 4 Fort Zhi was covered by poison gas. Because the poison gas was released at night, the Russian army did not respond. Most of the more than 1,000 Russian soldiers in the No. 4 Fortress were poisoned and died without time to react. Although some soldiers realized that it was poisonous smoke, the chlorine poisoning attack was too fast. They did not have the equipment and methods to prevent chlorine, so they suffocated and died before they could run out.

At about two o'clock in the morning, the Russian Army's second river fortress, Fortress No. 1-7 and polyhedral fortifications such as a, e, zh and z were covered with chlorine fortifications for two hours before dissipating.

Since Duan Qirui and Lianghuadian did not know whether the poison gas was effective for the Russian army, the first release was just a test.

The Russian Army's Second River Fortress Defense System opposite is a powerful fortification with more than 100 fortress artillery, a large number of machine gun bunkers, and at least 20,000 people.

At this moment, I heard a miserable whistle from afar and then fell into silence, a dead silence.

Li Guodong said: "It seems to be effective"...

Duan Qirui and Liang Huadian looked at each other. Although they felt that there was some effect, they were not sure, so they sent a reconnaissance force.

Li Guodong immediately stopped him and said, "You let them go up and seek death?"

"How do you know if it's useful if you don't send someone up?"

Li Guodong smiled and said, "If the poisonous gas above has not dissipated yet, your people will die without any protection."

Liang Huadian asked, "What should I do? You can't wait, right?"

Li Guodong said: "Don't worry, my people have already gone to investigate, and there will be news soon."

Duan Qirui nodded and suddenly asked, "I don't know how to prevent this thing? What if several people have this thing one day and they will deal with us in turn?"

Li Guodong replied: "Our chlorine gas is just the most primitive poison gas, and it is easy to protect it. Just use a moist towel to protect your mouth and nose."

Liang Huadian asked: "Didn't you say that the chlorine gas is very corrosive? When it blows on people, the skin will be burned!"

Li Guodong smiled and said, "That's theoretically. Now our method of releasing chlorine is diluted by the air, causing the percentage of chlorine to decrease every second. Now, it is good if the chlorine purity in the enemy's fortress can be 5%. In this case, only inhaling chlorine will cause a fatal effect, and the corrosion to the skin is very light."

"So that's how it is!"

Duan Qirui and Liang Huadian were slightly disappointed.

After about ten minutes, a signal flare was fired above Fort No. 4, the second river fortress, and then signal flares were also fired above other fortresses.

Li Guodong laughed a few times and said excitedly: "Two commanders, congratulations on seizing the second river fortress."

Duan Qirui and Liang Huadian were immediately overjoyed when they heard this and immediately ordered about 2,000 soldiers in the first echelon to launch a quick attack.

Sure enough, in less than twenty minutes, the first attack echelon rushed to the Russian second river fortress without any obstacles. During this period, the Russian army resisted a little, but it was quickly destroyed.

At dawn, Duan Qirui, Liang Huadian and Li Guodong climbed to the Second River Fortress. At this time, more than 20,000 Russian officers and soldiers in the fortress were only left with corpses. Because the chlorine release conditions were too primitive, the Russian corpses were not terrifying. The burning scars were not terrifying as the incendiary bombs. Most of the Russian soldiers suffocated to death with tight necks.

When entering the command center of the Russian Second River Fortress, an officer who was cleaning the battlefield handed over the sword of Lieutenant General Menlegisky, the commander of the Russian Second River Fortress, to Duan Qirui.

Duan Qirui mocked this exquisite lieutenant general's knife and couldn't help but sigh: "This Menregisky blocked our fierce attack for more than ten days. He is also an admirable soldier. I didn't expect to die in this way. It's really a pity!"

Lianghua Palace also agreed with Duan Qirui's point of view and said: "He is indeed worthy of respect to being able to block such a powerful attack by the Emperor's team. If someone comes to bury him with a grand ceremony, he is worthy of the Emperor's courtesy."

"Yes!" The adjutant received the order and called several guards to carry the body of Lieutenant General Menregisky for a grand funeral.

Duan Qirui came to the center of the command room, and a huge map was presented in front of him. It was the complete military deployment map of the Vladivostok fortress. The coordinates marked on it, secret passages, underground bunkers, and military camps,

The ammunition depot, grain and water supply channels, etc., far exceed the intelligence information that Duan Qirui has.

"Look, with this thing, the Russian devils will suffer."

Because of the sudden attack of poison gas, the Russian commander had no time to destroy the map and ordered,

Password and other important documents.

"Now, even if we don't use poison gas attack, our artillery fire can accurately hit the enemy's vital points."

At this time, the phone rings suddenly.

The staff officer was about to answer, but Duan Qirui stopped him and picked up the phone in person. A whirlwind sound came from the opposite side. Although Duan Qirui didn't understand, he knew that he must be cursing people. Moreover, the officer who dared to scold Lieutenant General Menregisky might not have anyone else except General Alekseyev.

"Please tell General Alekseev that General Duan Qirui, commander of the Second Front Army of the Chinese Empire, sincerely invites General Alekseev to visit the Second River Fortress Headquarters. This invitation is valid within 24 hours. If he does not appreciate his face, this general will visit his office at this time tomorrow."
