More and more people are infected with cholera, and many people walk on the street and suddenly have a stomachache, they can't help it, so they just find a place to squat down to solve their physical problems, but many of them never get up again. The dead bodies on the streets soon piled up, but no one knew what to do. In the flu pandemic, the only way for countries to do so was to gather the sick and wait for them to die, but now there are so many sick people and there are not many healthy people left, and the quarantine policy is simply no longer enforceable.

Several cities, led by Fort Dodge, have seen unprecedented cholera outbreaks, while the situation in several others is very different. These cities start out with a fever, which can easily be confused with a fever and go unnoticed, but soon these people develop symptoms such as general malaise, fatigue, loss of appetite, sore throat and cough.

Soon the low-grade fever turned into a high fever, and many people were burned with nonsense, confused, and unable to return to normal consciousness at all, and many people were tortured to death by the high fever. At first, the relatives of these patients were still caring for them, but soon the families of these patients also fell ill. Many families were sick with typhoid fever, and more than seventy percent of the people fell into a coma, and in the end these people were not sick to death, but starved to death.

The epidemic of typhoid fever and cholera completely rendered dozens of cities near Fort Dodge completely incapacitated, and both civilians and soldiers died in large numbers, while the remaining people no longer dared to stay in these cities, and they fled one after another, fleeing to other cities that were not affected by the plague.

Cities that had already received the news soon began to carry out strict health checks, and if a patient appeared, regardless of the condition, he was sent to a specific area for quarantine, and those who fled were treated in the same way. The only way for these quarantined people to get out of quarantine is to survive the disease and recover on their own, but in an environment where there is little medical care, it is not easy to survive by relying on their own immunity.

After a dozen or so cities in the outermost part of Chicago's industrial area became empty cities, the Chinese army did not enter these areas in the first place, and hundreds of Kunpeng 3 bombers were the first to be dispatched, and their bomb bays were not equipped with deadly bombs, but some spillers connected to large barrels.

Bombers flew low over the city, spilling milky disinfectant all over the city. Disinfectant sprayed out from under the belly of the plane, splashing quickly, and these were just preliminary disinfections. After the plane, a large number of people wearing full-body rubber sealing suits entered the city, disinfected some dead corners with sprayers in their hands, and tossed for several days before the large forces of the Chinese army dared to enter these cities.

More than a dozen industrialized cities, led by Fort Dodge, fell into the hands of the Chinese Empire in this way. These dozen or so cities are used for basic industries, and almost all of the steel mills built here are one by one, as a key project of the Boston Empire's industrial state, the steelmaking enterprises in these cities are quite valued, and their equipment has been using the latest and greatest, and the quality of steel produced is the highest in the Boston Empire.

The loss of these steelmaking bases has slowed down the manufacture of high-powered weapons by Bostonians a lot, but fortunately, steelmakers are not the only ones here, and steelmakers in other cities can also support the consumption of Chicago's industrial area, but the output is much lower. After discovering that the Chinese army had easily captured more than a dozen cities, Marshal Pershing immediately flew to the Chicago Industrial Zone, where he found that the situation was somewhat serious, so he had to choose to take charge of the battle in the south and hand over the battle in the south to his deputy, Five-Star General Marshall.

Seeing the strange phenomena in more than a dozen cities, Marshal Pershing didn't know what secret weapon the Chinese Empire used, but he knew that if he only defended in the city, the Chinese Empire would destroy them little by little like it did with Fort Dodge, so Pershing had to take the initiative.

The 700,000 Boston troops were mobilized, and Marshal Pershing intended to command these forces and launch an offensive against the Chinese army. At first glance, 700,000 men was not a lot, and even Su Zhizhen, who had three million troops deployed on the frontal battlefield, was a small number, but Marshal Pershing thought that these men were sufficient, because they were equipped with a large number of new weapons that were newly equipped with the latest equipment of the Boston Empire.

Seeing that Marshal Pershing's troops had abandoned the city and attacked Fort Dowl, Su Zhizhen also led 1.3 million troops to meet him, and he wanted to defeat the Boston army in the field. Having mobilized most of the armored forces, the Chinese army rushed towards the Boston army in a neat formation, and for insurance, Su Zhizhen also asked the air force for support.

The charging Chinese charioteers soon saw a new weapon, and in the Boston people's charging ranks, in addition to the familiar M4 tank, a much larger new tank appeared, and they were the M5 Rat chariot. The ten-meter-long, three-meter-tall rat-shaped chariot rushed towards the chariot troops of the Chinese Empire with its 128-millimeter tank cannon and its slow speed.

Seeing such a big man in the opposing team, the gunners of the Grizzly 3 tank suddenly felt threatened, and they preemptively turned the 115 mm smoothbore tank cannon and aimed at the mouse tank a thousand meters away. Thanks to the installation of a two-way stabilizer and a hybrid independent suspension system with a torsion bar and spring, the Grizzly 3 has the ability to shoot accurately on the move, while the laser rangefinder and analog ballistic computer have greatly improved their accuracy.

Soon more than a dozen chariots were aimed at a mouse chariot that rushed to the front with a tank cannon, and with a tom of cannons, eighty percent of the shells hit the front armor of the mouse chariot, but after a cloud of gunsmoke, the intact mouse chariot reappeared. The thick front armor kept the Bostonians out of a deadly attack, allowing them to survive, and the Bostonians immediately began to fight back when they were bombarded.

Stopping its slow speed, the Rat turned its turret and aimed its 128-mm gun at a moving Grizzly 3, which was about to start firing. The 128 mm shell spewed out a fiery muzzle and hit the front armor of the Grizzly 3 directly, and the moving vehicle froze sharply, swaying from side to side a few times, and finally steady.
