The doctors who carried out bacteriological warfare, such as Shen Langzhong and Ma Yuanyi, have official positions, and germ warfare has been going on for several years.

As long as their subordinates seized the opportunity, they would sprinkle acne scab powder on the goods exported to the north, because either Jiannu or Tartar in the north were the enemies of the Ming Dynasty.

The promotion of cowpox to prevent smallpox infection in the interior of the Ming Dynasty has become the norm, and this plague has been effectively contained in the Ming Dynasty, so Shen Langzhong, Ma Yuanyi and others do not need to worry about the large-scale outbreak of smallpox infection in the territory of the Han people.

At the beginning of the first month, the Red Gang was overjoyed to learn that Lin Dan Khan had died on the way to flee to Qinghai, and he was particularly good at seizing the opportunity, and immediately sent Hao Ge to lead the Eight Banners and bring the Chahar cavalry that had returned to Shun last year to the area where Lin Dan Khan had been entrenched for a long time to surrender and conquer Lin Dan Khan's old army.

This time, Jiannu dispatched 4,000 men and horses from the two Yellow Banners, and 1,000 troops from each of the other six banners, plus half of the Gebush Xianchao Ha Battalion, with more than 600 men and horses, and brought 30,000 Mongolian light cavalry, with a total strength of more than 40,000, and claimed to be 100,000 to march west into the Hetao area.

Zu Dabi received a letter from the Fan family's caravan, which was written by his eldest brother Zu Dashou, and he was able to know in advance that tens of thousands of horses and horses from Jiannu and Tatars would come to Xuanda, Taiyuan Town, and Yansui Town near the border walls.

It's a great time to rebel and take a detour home, and it's safe and secure.

Therefore, when Hong Chengchou mobilized Zu Dabi, Zu Dacheng, and Zu Kuan, he was resisted, and the trick used was the common pawn of the Ming Dynasty.

At the beginning of February, the Zujia army mutinied and refused to go out of Tongguan to the east into Henan to kill the Liukou, and they took advantage of the fact that the Yellow River was still in the freezing period to go north to plunder and kill all the way to the west of the Shanxi and gallop in the direction of Xuanda.

Gao Yingxiang, Zhang Xianzhong and other thieves who took Fengyang knew that they could not stay here for a long time, and they divided their troops after a few days of sabotage, Zhang Xianzhong fought the most fiercely, and captured Chaoxian in a few days, and three days later, they attacked Lujiang again, and the next day they took Wuwei Prefecture.

On the first day of the first month of February, the thieves continued to seize the city and coerce the people, making his people as high as more than 200,000, and Zhang Xianzhong, who was in high spirits, led the army to besiege Qianshan County.

The thief got carried away for a while, and then he learned a lesson when he led the thief soldiers to take advantage of the situation to take Anqing Mansion City.

The layout along the river is the established strategy of Huang Han, Anqing is close to the Yangtze River, and the city has opened a "Sifang Qianzhuang" has long had a "Sifang Express" semicolon.

Last spring, the "Sun Moon Shipping" also operated a transit station in the city, and businessmen who had a cooperative relationship with the "Red Flag Army" also opened branches in Anqing.

The "Red Flag Army" system has now not only achieved river-sea combined transportation, but also Shizhu Xuanwei Division, Kuizhou Prefecture, Jingzhou Prefecture, Anqing Prefecture, and Nantong Prefecture have all become important starting points for land transshipment, and are also the main ports of the Yangtze River detachment.

Although the imperial court restored the establishment of the Longwu Naval Division, and the general Huang Yong was the main general, it was impossible for the Longwu Naval Division, whose home port was far away in Shanhaiguan, to get involved in the Yangtze River, and the banner of the Yangtze River detachment to maintain the safety of the Yangtze River channel was very chaotic.

There is the general of the Kuizhou garrison battalion with the help of Zhou Shideng, who has been promoted to become the envoy of Sichuan according to the inspector, and the commander of the Jingzhou Water Regiment, which was established with the support of Xu Mingyang, and the banner of the Shizhu Propaganda Division.

Zhao Kun sits in the "Wangchuan Fort" on the heart of the river more than 30 miles west of Jingzhou, which is the base camp of the Yangtze River defense line of the "Red Banner Army", which is easy to defend and difficult to attack.

When he was in charge of the layout of the Yangtze River, he had to ensure that the cities he was infected with could not be breached by the enemy, and the Qiwei and the men and horses of the "Red Banner Army" left in Sichuan and Huguang were working hard to achieve this.

Dongping Hou is good at management, and his business is so big that it has been done all over the Ming Dynasty, and even Chongzhen knows it.

The "Red Banner Army" system touches a city, and it is impossible to blatantly send troops to hold high the red flag, and they all enter with a business model.

Of course, the magistrates knew that these were the properties of the Marquis of Dongping, and they basically didn't dare to have them, but Huang Han didn't bully people, and the taxes that should be given would not be less, and the benefits that should be given to officials at all levels were indispensable.

The garrison of Anqing Fucheng has been completed, the grain depot, the silver warehouse, and the warehouse of products in the system have begun to operate, and the broken city will not only lose too much property, but also many soldiers and civilians in the system will die in battle.

Zhao Kun's task is to guard and run the "Wangchuan Fort" well, where there are already 200,000 acres of land, more than 10,000 households, and a population of more than 150,000.

Many factories and workshops are already in production, including 3,000 part-time villagers, 1,000 full-time guards, and three general infantry officers of the "Red Banner Army."

Since all the cavalry and war horses went north in order to cooperate with the head of the family to enter King Qinqin last summer, Zhao Kun finally got a few hundred horses and formed a new general trainee cavalry to step up training.

The Yangtze River detachment led by Yu Quanzuo took "Wangchuan Fort" as its home port, and under normal circumstances, dozens of gunboats and hundreds of sailors and gunners were stationed here.

The "Wangchuan Fort" is in an important position, and it is impossible for Zhao Kun to leave here in the past two years, nor will he leave the Yangtze River, which is convenient for dispatch and support.

For the sake of safety, Zhao Kun promptly dispatched Yu Quanzuo and Pei Yuanwu down the river to Anqing Mansion, which had just been in operation for less than half a year.

The propaganda team tried the general flag, Luo Mingshi, with a small flag, and 11 armed propaganda team members also came to Anqing Mansion to carry out their work.

The constant flow of gunboats on the river is a symbol of strength, and officials in the cities and counties along the river buy it, and they often even ask gunboats to escort them.

In order to do business with the imperial court, the "Sifang Qianzhuang" had to deal with the magistrates, and the chief official of Anqing Mansion was no exception.

The rogues swept through the capital, too many cities fell, and the scholars and landlords and squires were rarely able to escape under the ravages of the bandits, and often died miserably, and the female dependents in the family were even more miserable.

The rogues were so cruel and inhumane that they forced the landlords and bureaucrats to share the same hatred.

The magistrates of Anqing took the initiative to contact the "Sifang Qianzhuang", "Sifang Express" and "Sun and Moon Shipping" to live in Anqing Mansion.

They hoped that they would be able to get support from the river in case the city was attacked, and more people hoped that they would be able to escape on the gunboats of the "Sun and Moon Sea" when the city was in danger.

On the day Pei Yuanwu and Yu Quanyou came to Anqing Mansion, they were treated like guests by the magistrates.

They were not hypocritical, and expressed their willingness to lead their subordinates to assist in the defense of Anqing Fucheng on the spot, and in order to justify the name, they rushed to bring two "Red Banner Army" with a total of 720 infantry to become local regimental training.

For the sake of safety, Yu Quanyou temporarily dismantled part of the warship artillery and sent sailors and gunners to participate in the defense of Anqing Fucheng.

At the same time, the investigation and killing of traitors and the people, and the major families have also carried out the training of the township braves in a sound and impressive manner.
