From several earthen platforms that were quickly piled up in the south of Jiaozhou City, you can see that the civil engineering operations are gradually approaching the city, and for a moment there was no cracking measures or actions on the top of the city; in a blink of an eye, the original range of the river embankment was broken from the southeast and approaching a hundred steps below the wall. Then you saw sparse arrows shot over the city, but were blocked on the preset mud cover.

However, the progress of the siege was limited to this. For a moment, the defenders in the city could not come out to fight back, and the rebels could not attack for the time being; because this was a large city with high walls and thick walls; if you want to cut off the river and drain the water of the moat, I am sorry that the Red River and its tributaries are not small ditches, and just building dikes is a long-lasting project.

I want fire attack, sorry, this is a river surrounded by water sources in the city, so it can be said that it is extremely convenient to obtain water; if you want water attack, you can block the Red River and flood the water, so Jiaozhou City should be almost knocked down.

As for attacking the ground, I'm sorry to dig tunnels by the Honghe River, it's not that drowning is not fast enough. It's not easy to find large trees that use various equipment to build on the Honghe Plain, where agricultural development is very high. In fact, the local building materials come from the mountainous areas flowing through the upper reaches of the Honghe River.

If this is the case, it would be easy, but just to push the well-built siege equipment into the city and play a role, it is necessary to overcome the three obstacles of the river embankment, river channel and chest wall under the obstruction and counterattack of the defenders.

It can be said that when Gao Pian built this Daluo City, he considered the possibility of being besieged and trapped for a long time in the plain water network area that was not dangerous to defend, and he carried out targeted prevention and countermeasures in the city defense layout one by one.

With this big city as support and support, with sufficient materials to be prepared to defend for a long time, it will be the biggest obstacle and trouble that no force wants to occupy and control Jiaozhou cannot ignore and circumvent;

This is the water and land transportation hub and heartland area of ​​the seven prefectures in Annan, north and south. Once the Honghe Plain changes hands, it can be used as a support base and the support behind it, and it is very convenient to rely on the advantages of water transportation to divide troops out and pacify various places.

As early as when Gao Pian built Daluo City, the military and civilians of Jiaozhou, led by the former defender Cai Xi, withstood the several sieges of tens of thousands of troops in Annan with a sub-city. Finally, when the Pang Xun Rebellion broke out for a long time and the reinforcements were not arrived, the soldiers in the city were killed and injured and their morale was low, and they failed to break through the siege and were defeated.

Therefore, the current countermeasure is to focus on siege and attack the heart; the real key is to change the heart of the people in the city. Thinking of this, Zhou Huaian's eyes seemed to have fallen into the inner city where the wealthy families lived through the thick walls.

But I didn't expect that one day I would need to negotiate with these targets that should have been overthrown and beaten;

If it is someone else's words, you may be able to persevere in this Jiaozhou city for a while, but most of their land estates, even relatives and tenants are under the control of the rebel army; and under the influence of personal strength, you need to make corresponding choices to preserve all this.

Otherwise, even if you successfully defend Jiaozhou in the future and lose the foundation accumulated by these generations in the local area, the so-called title of a powerful household will become a joke in a sense;

At least, as a substantial threat in a sense, Zhou Huaian did not mind distributing these rebellious properties that dared to fight against the rebel army to other local forces that attached themselves; and further trained and armed them to annex and invade more of the rebellious party foundations who were not obedient to education, were not tactful, and did not know the general trend.

"Report to the leader...I am a man who inspects the outside camp"

Qu Chengyu, dressed in a dress, walked over and whispered.

"I found that several people from the city tried to sneak in, trying to do something that lobbying and rebelling..."

"It's just that I've been arrested by patrols, or my tent is tied up and taken out... I'm under investigation..."

"You did a good job..."

Zhou Huaian nodded slightly and affirmed.

"This generation actually wanted to use the same trick again, but he made a mistake in his plan. He tied the person to the flagpole and showed it to the public."

"Then, I will arrange for the relatives related to the guards to go to the front of the formation to call in turn as a reward for the gift."

"In addition, how did you persuade Fan Chuo?"

Zhou Huaian continued to ask again.

"After I understand the pros and cons, my attitude has been loosened."

Qu Chengyu said the way he wanted to stop.

"It's just that guy asked if he had something to meet the leader."

"Is that..."

Zhou Huaian was slightly surprised and said unconsciously.

"Then let's see him just now."

But then he was distracted by another sudden news because dozens of reports of infection had appeared in the besieged military camp;

But it is not an intestinal infectious disease like vomiting and diarrhea, but a typical tropical disease sign of cold, fever, night sweats and loss of strength. This also hits Zhou Huaian's long-standing concern and expectation; since ancient times, the Central Plains army has suffered defeat and reduced personnel in the wild areas of the southern border, and the various tropical diseases prevailed in the local area;

Although in most cases, most of them can be prevented and prevented by strictly abiding hygiene habits and efforts to keep the environment clean, such as high-temperature sterilization, fire roasting, vinegar smoke, lime sprinkling and other disinfection methods; however, it is still somewhat difficult to prevent malaria-like infectious diseases carried by mosquitoes and flies.

You should know that although pyrethra native to Europe was not introduced to China until the 20th century; there were already products similar to mosquito coils in this era; they were to twist mugwort and yellow poles into ropes, and ignite at night to slowly smoke to repel mosquitoes. Compared with the curtains that most people cannot afford or the incense that can only be used by wealthy families, it can be said to be a cheap solution for poor families;

Therefore, similar medicinal straw rope products were also widely made in Cantonese and widely used in the army expedition to Annan. Despite this, it is still inevitable that they will be bitten by local mosquitoes during daily service and labor activities, and there is a certain probability of being infected with local subtropical diseases.

However, this is nothing to do. At present, we can only rely on physical fitness to survive and further strengthen environmental sanitation management, such as burning reed marshes near the camp and staying away from sewage pits, where mosquitoes and flies are prone to breeding, to reduce the probability of corresponding infection.

Although Zhou Huaian also knows the principles of artemisinin and Artemisia sago as a substitute for malaria-specific drugs; under the current simple conditions, there is obviously a long way to go to extract effective ingredients and make medicines; as for the cinchona tree native to the Americas, it is still out of reach now.

At present, it was not until the city of Jiaozhou that these dozens of cases were discovered, which was a blessing in disguise. The main thing was to try to select soldiers from the southern region, and use the newly attached Long March garrison soldiers and Guan Jian as the front and guide of the army, scouts, and teams that went out to patrol and raise grain, which avoided the worst result.
