The weapons and personnel are more elite, but the number is smaller, if the Chinese army enters the city, a little bit of street fighting, heavy casualties are certain, once the casualties are too large, even if the place is fully occupied, it will be difficult for him to continue to move forward, so Su Zhizhen hopes to find a way to quickly destroy the enemy, although he knows that Fang Ruijun wants to preserve this industrial area, but for the sake of future victory, he has no choice but to destroy this place with heavy artillery.

After reacting the current difficulties to Fang Ruijun, a giant beast Type 3 transport aircraft wing that set off from China quickly transported a lot of special shells painted red, and with them arrived a special artillery unit, which was subordinate to the unit directly under the Second Artillery Corps. Soon the train will unload a new batch of 155mm howitzers from the harbor, which have a deeper barrel and a completely sealed gun mount, which makes for a rather novel look.

Under the heavy escort, these artillery pieces were quickly transported to the front line, and in addition to some soldiers of the Second Artillery Corps, there was also the commander of the Second Artillery Corps, Second General Xiao Jun.

"Old Xiao, why are you here?" Seeing Xiao Jun walking into the headquarters, Su Zhizhen's face was full of surprise, but he didn't expect to ask for instructions on the battle plan, and he actually attracted the commanders of the Second Artillery Corps.

"I am at the request of the young master to personally supervise this operation, because this time our Second Artillery Corps is going to use a special weapon, and I must personally command it, because once something goes wrong, it is easy to cause unpredictable big things." Xiao Jun said it quite seriously, which made Su Zhizhen also look upright.

"What special weapons are you going to use? If there is such a powerful weapon, why not use it earlier? Su Zhizhen asked.

Xiao Jun looked at the left and right with a smile on his face: "The little young master has always hoped that we will keep the industrial area while eliminating the Bostonians. This is the largest industrial area in the Boston Empire, controlling half of the heavy industry in the Boston Empire, and you should be well aware of the weight of this. ”

Su Zhizhen nodded and said: "Yes, if we can obtain this place, we can achieve self-sufficiency in a short period of time in terms of the supply of weapons and equipment on the new continent, which will greatly reduce the transportation intensity of the logistics troops." It's just that it's too difficult to wipe out the Bostonians and save the industrial area. ”

Xiao Jun said: "So we came, we brought the latest weapon secretly developed in China, this weapon can kill people invisibly, but it will not damage other facilities." However, this weapon is very dangerous and effective against our troops, so we must prepare ourselves first. ”

"Could it be a chemical weapon that was once used in the Wa Kingdom?" Su Zhizhen looked sideways, as a high-level military official, he was still very clear about the secrets of the year.

"No, chemical weapons are easy to detect and fall into the hands of people, and what I brought this time is a virus, that is, a biological weapon." Xiao Jun said in a low voice.

"Biological weapons? Virus? Su Zhizhen exclaimed, this kind of weapon was unheard of even in his capacity as commander-in-chief of the army.

"It's a shame to be quiet, let others know." Xiao Jun was so frightened that he waved his hand again and again, and Su Zhizhen, who was out of shape, quickly covered his mouth.

At the beginning, international conventions only explicitly prohibited the use of chemical weapons, and it is true that no country has used chemical weapons in all wars over the years. The main reason for this is that everyone knows that this weapon was first invented by the Chinese Empire, and although they do not use it, they will definitely not stop researching it. No matter how much they study, they will certainly not be able to surpass the Chinese Empire, and if they use their own chemical weapons, they will easily be retaliated against by the Chinese Empire, which will outweigh the losses.

The Chinese Empire has never admitted to using chemical weapons in the Japanese country, because it does not want to damage the country's image, and in all previous wars, the Chinese Empire has an absolute advantage, and there is no need for the help of chemical weapons, and for the sake of its own image, the Chinese Empire will never use such weapons again.

Biological weapons, on the other hand, are themselves virus-spreading. Viruses are an inherent species in nature, as long as the Chinese Empire does not admit it, no one can impose a crime on the Chinese Empire, because they can completely use the plague to prevaricate, and after a series of wars, there are many dead, these corpses are easy to decompose without burial and produce a large number of viruses, the virus spreads through the air, and it is normal for epidemics to occur.

With such a hidden benefit, Fang Ruijun naturally took out this weapon. A few days later, the Imperial Chinese Army entered the area near Fort Dayle, on the edge of Chicago's industrial area, and they used artillery to carry out a tentative artillery bombardment of the perimeter of a dozen cities, including Fort Doyle.

Most people didn't notice that some of the artillerymen who fired the shells were dressed in completely sealed rubber suits and carrying oxygen cylinders, and they were all careful to handle the red shells, as if they were afraid that something might be in danger.

Next to the strange artillerymen were many men with large canisters on their backs, also wearing rubber suits, and after firing ten shells, they all rushed up, pressing the switch on the tube with one hand and spraying around the cannon with the other with a nozzle like a pesticide for a fruit tree.

The bombardment of the Chinese Empire left the Bostonians a little confused, they did not understand why all the troops had retreated into the city, the Chinese Empire was still only firing shells at the edge of the city, and only a few shells fell into the city, and finally they agreed that the Chinese Empire was testing the minefield.

The Bostonians did lay some mines, but after all, this was on their own territory, and the Bostonians did not want to leave too many hidden dangers, so only a few small areas of minefields were laid, and those heavy artillery shells did detonate a lot, but detonating the mines was not the ultimate goal of the Chinese army.

Eighty percent of the hundreds of shells that fell into several nearby cities during the shelling were special shells made of ceramic linings, the metal shells of which were first blasted in the air by a small amount of explosives, while the ceramic part of the inner tank did not explode after landing, but was directly smashed. While people were hiding from shelling in fortified houses or fortifications, no one saw countless fleas and cockroaches jumping out of the shattered ceramic bullets.

"What kind of virus are you launching?" Su Zhizhen deliberately kept the guards far away, so he dared to ask Xiao Jun in a low voice.

Xiao Jun, who was standing on the battlefield, replied in a low voice: "We also came out this time to experiment with new weapons, and we need to observe the effects of various viruses, so we can't release too many types at a time, this time we only released two viruses, that is, Vibrio cholerae and typhoid bacillus." ”

"How can we defend against viruses? Don't put ourselves into it. "Su Zhizhen is most concerned about not hurting her own people.

"This is easy to do, you see I brought so many people, in fact, biological artillery only accounts for a small part, most of them are specialized double defense soldiers, they can not only prevent chemical weapons, but also put an end to the spread of biological weapons, as long as all soldiers are injected with vaccines in advance, it will be fine, and now they are doing it in the name of physical examination."

The Chinese army did not continue to advance, the whole army camped on the spot, and all the troops were in a state of rest except for vigilance, which made the troops who had fought so many big battles with high intensity very uncomfortable, and a group of officers asked Su Zhizhen to fight every day, but they were all reprimanded. Su Zhizhen told them that there have been too many casualties in the recent war, and the plague is very likely to occur, and the Chinese army should conduct a health inspection to avoid the formation of the plague.

Taking advantage of this respite, Su Zhizhen carried out a general inspection of the whole army's sanitation, not only to eliminate sanitary dead ends in the camp, but also to bury quicklime and sprinkle disinfectant around the camp by many people wearing rubber sealed suits, and the soldiers were also strictly forbidden to drink raw water and maintain good hygiene habits. Everyone was very strange that the battle was fought so well, how it was suddenly clean, and it was still in a temporary camp, which made the officers at all levels a little confused.

In more than a dozen cities, such as Fort Dodge, there have been unpredictable epidemics. The virus that has been specially activated by scientists is much more transmissible, and the condition at the time of onset has also been enhanced. The day after that headless shelling, an outbreak broke out among Boston residents, and some began to have diarrhea. When it first appeared, people thought it was because they drank raw water, and diarrhea was a common disease that was not a big deal, so no one paid attention to it, but soon things were not normal.

In the cities that have been attacked by biological weapons, people with diarrhea have not been cured, and they have diarrhea more and more often, accompanied by vomiting. Soon the whole city was full of people with diarrhea, and the feces that had not had time to deal with made these cities stink, and people who were not sick felt like they were going to vomit. The condition quickly deteriorated as it spread rapidly, and those who first started diarrhea began to have blood in their stools, most of them with deep-set eyes, hoarseness, dry skin, and often even symptoms such as muscle cramps.

When there was death among the first people to have diarrhea, people began to panic, realizing that this was not an ordinary diarrhea, but the arrival of a plague. The Boston army had long been mixed with civilian warfare, and they did not have the slightest precautions, and soon there was diarrhea among the soldiers. Under the influence of Vibrio cholerae, more and more people died from diarrhea, and at this time, the commander of the Boston people finally realized that this phenomenon in the city was not as simple as eating bad food, but a large-scale outbreak of plague, but it was too late.
