"I have heard that Li Su and Li Boya have been full of tricks. He has only been here for more than a month. Liu Bei's army has had more tricks to siege the city. Damn, if we continue like this, how long can our army's ration last? Otherwise, we will endure this winter and make Liu Bei's morale so exhausted that the teacher and veterans are tired. Let's ask his father for help and ask him to send the main force to fight Liu Bei in a decisive battle?"

Seeing the recent losses reported by his subordinates by the enemy's catapults and firewood were burned by the enemy's catapults, Liu Mao was simply the first to be two big. For the first time, he had fundamental doubts about how long he could last.

I had originally agreed to eat food and grass for more than fifteen months, but as I was forced to release so many surrendered soldiers, I could only eat it for one year at most. A small batch of food scattered at the forefront was burned, and I guess I could only eat it for ten months.

Fortunately, the main granaries in Diaoyu City are all in the Diaoyu Mountain area, with strong defense and high positions. It is impossible for the enemy's catapult to hit such a high position, so more than 80% of the grain storage is absolutely safe.

But who knows if Li Su will have another trick in the next step?

Starting from early June, Liu Mao fell into a suspicious state and couldn't sleep well every night, for fear of any new bad news or fatigue.

On this day, it was about the sixth day of the sixth month. Liu Mao was awakened by Liu Bei's bluff in the middle of the night. He finally fell asleep again in the early morning, but not long after, just dawn, and a confidant school next to him came to wake him up.

"Criminal, it's not good. Look at what this is in the sky? There is ghost fire in the sky!"

Liu Mao rubbed his eyes and ran out quickly. He saw dozens of hazy places in the misty morning light, as if shrouded in gauze paper, firelight flying in the sky, like large fireflies.

"What is this? Can Li Boya still make something that can fly?"

Seeing these Boya lanterns (Kongming lanterns) flying into the sky above Diaoyu City, the soldiers and officers below were all panic.

There is no way, things that are controlled by human power and can fly are too shocking for people of this era, let alone fire. Many illiterate soldiers were even frightened and treated them as something of a supernatural manifestation, kneeling down and praying, complaining about remorse, even if these lights have no attack power on them.

The batch of lamps made by Li Su are actually larger than the conventional Kongming lanterns. After all, one or two pounds of sugar and tincture oil is required to increase the density difference of several cubic meters of hot air by simple physical calculations. Therefore, the largest one has the bamboo strips inside it that are seven or eight feet tall, which is not an exaggeration to say that it is a small hot air balloon.

No matter how big the paper strength of this era is, the lamps were made two or three days ago, but it was not until today when the wind direction was released. When the lights flew to the same position, the hand of the lamp would tear off the thin kite string, and the candle inside the lamp would be broken and fell into the turmeric oil sac, which would immediately turn the lamp into a large fireball and fall from the air. (In order to reduce the weight, it would not be used as a container, but used a pig casing for sausages. It would not leak after half an hour)

Liu Mao, Liu Xun, Wu Yi, and the main generals in the city soon gathered nearby to watch and were closely alert to further changes.

"Hula~" With a sound of wind, they watched a ghost fire lamp turn into a ball of fire in the air, rolling down, landing on a brick and wooden house in the city - of course this place is not a granary, at least a hundred feet away from the nearest granary. The hot air balloons that flutter in the wind were unable to aim at it.

But that's enough, because once the city guards discover a new attack method that can make them beaten for nothing but they have no possibility of counterattack, morale itself will be greatly hit and chaos will appear.

"Put the fire quickly! No matter whether the house is heavy or not, anyone who is lit by the sky lantern must be rescued immediately! Don't be in chaos! Those who are in chaos will be killed!" Liu Mao was also very aware and instantly realized that he wanted to consolidate his morale. The most important thing at this time is not to be afraid.

Dozens of lights fell one after another, quickly making the fire-fighting soldiers at a loss, each rushing to their own, and stirring up a ball.

In fact, only 20 to 30% of these lamps fell on the house, and they were unable to find a target. They just smashed the house, causing seven or eight effective fires.

However, in the chaos, more troubles arose one after another.

"Not good, the granary in the north of the city is also on fire! It was hit by the ghost fire lamp!"

Liu Mao was shocked and looked up. There was indeed a granary fire in the distance. He didn't remember that a ghost fire lamp was flying in that direction just now, so why did it hit it?

Could it be that they had made some tricks by releasing them into the prisoners before? Or were some of the prisoners originally corrupted by the Han army's delicious food and drink guesthouse and were secretly surrendered?

"Hurry! Put out the fire! The guards guarding the granaries in various places should not be moved lightly! Special personnel are assigned to prevent fires from being put out elsewhere! Those who leave their posts without any excuses for fire elsewhere will be killed!"

Liu Mao was worried and added some orders, and finally stabilized the situation a little. This was also impossible. Although he was older than Liu Bei and was over thirty years old, he had never fought a war before, so he had no experience.

But the soldiers in the city were panicked. It has been rumored these days that the Han army's logistics was too strong and it would definitely not be able to consume it. This made Liu Mao frightened and unable to trust others.

After some trouble, at last, some losses were calculated at dawn, and at least more than 10,000 stones of food and grass were burned.

After the cessation, Liu Mao tried to thoroughly investigate whether all the prisoners who were released were betrayal, but such a thing would definitely end up in the end.

Two days later, a school came to report and said that some soldiers took advantage of the opportunity to go to the north river beach to draw water to secretly escape and defect to the enemy. It was probably the fine works that had committed the crime and the traitors who had previously been involved in it. Liu Mao had to bite his teeth and swallow it, but he only asked him to strengthen his defense on duty day and night and no longer pursue the matter.

...

"These tired enemy techniques are also effective. If you have a few more moves, the morale of the defenders in the city will definitely collapse. If you try to attack and surrender, you may have a decisive flaw."

Li Sugou observed in the distance for a few days and found that his disgusting harassment had indeed made the enemy disgusted. He couldn't help but feel proud and was about to further destroy it.

However, it is also possible that he did too much inequality and was too harmful to his good deeds. After returning to the camp that day, Xu Huang, who had been in charge of land siege on the eastern front, came to report to him a bad news, interrupting Li Su's original rhythm.

"What's the point of Gongming?" Li Su saw Xu Huang's face was frightened and signaled that he didn't have to be nervous.

Xu Huang bowed and sighed, "Zhonglang, our Hedong soldiers are all from the northern region, and they are not withstand the heat of Ba County. It is now the end of June. Many soldiers are sick and are afraid they are infected with miasma. They also beg Zhonglang to ask for help from the general in the west and send more reinforcements to replace the defenses, so as not to be caught by the enemy's chance to break through or go out of the city to counterattack."

Li Su was shocked. The army was not accustomed to the local conditions and became ill. This was the most important thing for the army to pay attention to when fighting in the south.

Last year, Zhang Lu was put down, and the battle ended at the end of May. There was no military operation in the hottest June and July of the lunar calendar. The problem of northern soldiers being invaded by miasma, subtropical jungle disease or other infectious diseases is not very serious.

But this year's Diaoyu City Battle is not intense, but it lasts for a long time. Now it's been suffocating until the end of June. Isn't it a period of concentrated outbreaks for the physical problems of northern soldiers?

Zhang Ji, Nanyang, has not written "Treatise on Febrile Diseases". People in the late Han Dynasty still had a cognition of infectious diseases. However, Li Su had to be cautious. He quickly asked what diseases had occurred in the army.

Xu Huang: "Some soldiers had swollen belly, yellow face, and vomited and diarrhea. Some were unknown fevers."

Li Su frowned. He knew that the Han Dynasty called many infectious fevers "typhoid fever". It is estimated that among the people who had problems with Xu Huangying, there must be typhoid fever.

As for the swollen belly, pale face and thin muscles, it can also be contagious... Could it be Schistosoma schistosomiasis? Did the troops eat snails or other snails? Or did they eat uncooked snails (snail greens) that are made of snails?

No matter what, it is probably caused by digestive tract.

Li Su didn't care what was sick, but a few warnings from Polyglass were not wrong: "Immediately ask the army of traditional Chinese medicine workers to treat them! I will go to Dianjiang County and invite some medical workers to come. The soldiers with signs of illness were immediately isolated, and all excreted were buried, covered with firewood and burned, and lime sprinkled!

All drinking water must be taken from the living water in the upper reaches of the Jialing River! If the river water is unreliable, then dig a well and the drinking water must be cooked! The diet must also be thoroughly cooked! Are there soldiers who eat raw green fish meat that eats snails? Military rations must be uniformly distributed. You cannot catch fish and replenish food just because you are idle along the river. Those who violate the order will be killed!"

After Li Su gave these instructions, Xu Huang must be sure to supervise the army completely. Fortunately, Xu Huang is also a good person in charge of the army. After writing it down, he will strictly implement it immediately.

Li Su felt a little scared and didn't dare to go to Xu Huang's camp to wander. Instead, he quarantined himself for three or five days to ensure that he had no problems for the time being. He told Xu Huang, Zhou Tai and others that he would first go back to Dianjiang County on the other side of the river to live.

If there is any military situation, I will send someone to write a letter to report to him. Don’t write the letter on paper, but write it on bamboo slices (Li Su will boil it in the soup and read it again when she receives the letter, and it will be cooked on the paper)

Of course, in order to appease them, Li Su also commended their performance in the siege in the previous stage, and also fulfilled the reward for promoting Gan Ning from Qujun Hou to Sima of another unit, to reward him for killing Gao Pei and defeating the enemy's grain transport fleet.

As for Zhou Tai and Xu Huang, they were just besieged for the time being, and their contributions were not obvious and they could not be promoted. However, Li Su also promised that when Diaoyu City was broken, there would definitely be promotion, stabilize people's hearts and let them continue to stay where they are working.

These generals are in good health and are not easily infected with a little infectious disease. How could Li Su, a weak strategist, take the same risk as them? It is better to go back to the county town to boil water and take a bath after cooling it every day, pay attention to personal hygiene. In winter, Li Su only cooked some hot water in the bath, and did not require it to be boiled thoroughly. He could also mix cold water to a suitable temperature before washing.

But now I heard that there may be schistosomiasis, Li Su immediately asked his bath water to be completely boiled. Even if he used cold water, it had to be cold water, not raw water.

Although it is a bit wasteful and does not conform to "sharing the joys and sorrows with the soldiers", who made him the General of the Central Army and the highest commander of the Diaoyu City War Zone?

Li Su was so cowardly that he was not caught by infectious diseases, but Xu Huang's situation was relieved slowly. The spread of schistosomiasis was distinguished by diagnosis and isolation and control.

But soon discovered that there were also supplies cattle responsible for the "last ten miles after unloading the ship" transport work, which was infected with subtropical diseases, and many sick cattle died. These cattle were transported by vehicles when they followed the army into Sichuan. Northern cattle were infected with bacteria and viruses because they were not adapted to the pests and diseases in the south, and they were inaccessible.

Li Suyan ordered Xu Huang not to let the soldiers be greedy and not to eat beef that died of illness. He would rather burn the plague directly.

However, just after Li Su gave this order, he suddenly remembered a game he played in his previous life called "Fortress". In that game, there seemed to be a siege weapon "Sick Cow Cannon", which replaces the stone bullets thrown by ordinary stone casters with cow corpses that died of infectious disease...

"It should be the hottest time of the year... Hiss, I remember that I have been observing these days that the soldiers of Diaoyu City also want to fetch water on the Jialing River beach outside the north wall, and they will use ox carts to pull water back to the city along the slope...
