At first, Zhao Yu thought that although the exiled court had lost a large part of the country, Liangguang, Fujian, Jiangxi and other places were still intact, and the local power was still there. And the sea in the Jiazimen area is complex, easy to defend and difficult to attack, there is Wen Tianxiang's governor's army in the northeast as a barrier, the Yuan army will not easily hit the front of them whether it is from the waterway, or by land, as long as they hold out for another two months to wait for the Yuan Dynasty to have civil strife, the army is transferred north to quell the rebellion, they can tide over the current crisis.

But Zhao Yu came to this world not long after all, and his understanding of this era is very one-sided, and he takes it for granted that he thinks about problems with modern inherent concepts. He thought that it was not a difficult problem to raise materials, but he did not expect that the contradiction in the supply of rice and grain in Fujian in the Song Dynasty was the most serious in the country, especially after the founding of the Southern Song Dynasty, a large number of immigrants from the northern region poured in, so that the food needs of Fujian, which was barren in many mountains and land, reached the point of 'no rice in the south ship to the city'.

Now I want to come to the imperial court to evacuate Fuzhou to Quanzhou, in addition to the attack of the Yuan army, the main thing is to solve the problem of eating, but the imperial court forced after Quanzhou surrendered the enemy had to continue to the south, and the Song army's successive defeats and retreats, losing the city and losing the land, so that they did not dare to continue to retreat south, and could only stay in the Jiazimen area between Guangnan East Road and Fujian, but the problem of food shortage still could not be solved, so that money could not buy it, and even produced the local Haoqiang who was awarded the title of Zhongzheng Doctor after only three days of rations, which is incomprehensible on weekdays.

As a result, Zhao Hao began to worry that the food crisis and the continuous approach of the enemy army would make the ******, who had become a frightened bird, drift on the sea again before the Yuan army could retreat north, which was different from his previous estimate that the imperial court would stay in Jiazimen for a long time. Knowing this, it is not difficult to understand why the imperial court only issued useless coupons to the volunteers, they wanted to keep food for the escape, but this made Zhao Yu, the 'careful and kind' prince, not only have to solve the problem of eating in front of him, but also think about what to eat when he floats to the sea.

That night, Zhao Yu summoned Zhuang Shilin alone to ask him for advice, thinking that he was so valued by the prince, the flattered Zhuang Shilin gritted his teeth and said his plan. In the past, most of Fujian's grain was transported by sea from Liangguang and Guangzhou, but now the Yuan naval army is rampant on the sea, and the maritime merchants all know that they have lost their things, and they can't even go back with their boats and people, so foreign grain cannot enter, which makes the shortage magnified. On the contrary, Guangdong must have hoarded a large amount of grain that could not be shipped abroad, and the price was lower than in the past, as long as you go to Guangzhou, you will not have to worry about not being able to buy grain.

Zhuang Shilin's plan is said to be feasible, but there are also dangers. One has to risk the robbery, and it may be empty of people and money; The two are not waiting to buy grain to come back, and the court has already left; The three are that they absconded with money or defected to the enemy, although this is not on the table, but it is the most likely thing to happen at this **** time. But if you succeed, the benefits you get are also great, not only to keep the little money you have just saved, but also to increase cohesion and lay the foundation for the future. After thinking about it repeatedly, Zhao Yu decided to take a gamble and fight for his character.

Subsequently, Zhao Yu and Zhuang Shilin agreed on specific details. Due to the increasing population of Fuzhong, the food stock is only enough for six or seven days, and even if you save some, you will not be able to last ten days, and the enemy army may reach Guangzhou at any time, so you must go back quickly. After calculation, it will take 2,000 stone of grain to maintain a month's normal use in Fuzhong, and considering that there will be people who will take refuge, at least 3,000 stone of grain will be bought back this time to be more spared.

In the end, the two decided to send three 2,000-stone sea ships that originally belonged to Zhuang Shilin, although the number of ships seemed to be small and the resistance was weak, but at the same time, the probability of being found in the vast sea was also low, and even if one of them was lost, as long as the two ships returned safely, they could meet their needs. In order to be more secure, after they went to sea, they pretended to be Semu merchants, who were allies with the Yuan Dynasty, and would not embarrass them when they encountered the Yuan army under normal circumstances.

Considering that there may be large fluctuations in food prices now, Zhao Yu granted Zhuang Shilin the right of expediency, which can use the funds in the palace at will and act in the name of the Wei Wangfu. However, in the course of the conversation, he listened a lot and talked a lot, first, he was not an expert in doing business, and he was not familiar with the rules of this era; Besides, you have to be more reserved, and you also show respect for their opinions, after all, your age is there, and you know everything, isn't it really a monster......

"Where did it come from?" After a day of preparation, Zhuang Shilin set sail with His Royal Highness's token, and Zhao Yu was able to sleep peacefully, but when he walked out of the bedroom in the early morning, he smelled a strong stench, and he frowned and asked Wang Dedao.

"Your Highness, the smell came from the outer courtyard, where there were more and more people, thousands of people crowded together, eating, drinking, and sleeping in it, and these people were all rough men who didn't know how to check, so they ......" Wang De snorted and said with a wry smile.

"Oh, I see!" Zhao Yu suddenly realized that the handling of urine and urine of so many people is a problem, plus these people do not have good living habits, and the health situation does not need to be seen to know what it is like.

"Your Highness, it's time to take care of them." Wang De used to live in the palace and was used to being clean, where had he ever seen such a sloppy scene, and he had long been dissatisfied with these people, but he didn't dare to say anything because of the protection of His Royal Highness, and now that he has a stubble, of course he doesn't want to let go.

"Okay, I know, it's time to clean up, otherwise something big will happen." Zhao Yu nodded.

"Your Highness, those villagers received His Highness's grace but did not think of reciprocating, they just kept making trouble every day, and they uprooted all the flowers and trees planted in the house, and they also defecated everywhere, making them dirty. Especially those monkey cubs, who climbed over the wall and entered the inner courtyard several times to peep, and also stole the food and clothing of the local villagers, and were chased to the mansion...... "Their opinions are rarely accepted by the prince, Wang De's spirit is greatly lifted, and he immediately becomes verbose."

"Uh-huh!" Zhao Hao kept nodding his head yes, but what he was thinking about was an article on military logistics that he had read in his previous life, which made him realize that he had almost made a fatal mistake of common sense.

Modern people know that they should wash their hands before eating and after using the toilet, clean up garbage in time, do not defecate in the open, eliminate flies and mosquitoes, etc., but they do not know that it takes 2,000 years just to get an army to properly dispose of drowning. At first glance, this may sound suspenseful, even alarmist, but it is actually true, and the reason is simple: for a large and often concentrated army, feces and garbage can easily lead to outbreaks of infectious diseases if not properly disposed of. It can be said that those invisible killers eliminate many more soldiers than the weapons directly destroy.

In this era, there were no automobiles or airplanes, and the army relied on animal power for combat and baggage transportation, so they would deal with animals every day. The terrible thing is that once livestock are infected, they can spread to people, which is too numerous in the history of warfare, and in Gallipoli during World War I, it was because of the dysentery of mules and horses that it was transmitted to the troops, which greatly weakened the Allied combat effectiveness.

Improper garbage disposal invites another uninvited trickster, rats, who not only gnaw on weapons made of rope or leather, but also spread diseases, often with catastrophic results. When the military wizard Napoleon invaded Russia, what made him most depressed was not the fierce Russians, but typhus, and less than half of the more than 400,000 recruits he painstakingly recruited could still serve. It was joked that it was the 'rat generals' who defeated Napoleon's generals – rats were the main source of typhus. A hundred years later, the Western Maritime Championship began, and the plague raged so much that it spread among the British army: chickenpox was on the deck, the plague was between the decks, hell was in the ship's towers, and demons were at the helm of the ship.

However, in the history of human warfare, there are very few armies who have come up with this problem, and the ancient Roman army did a good job, systematically digging field latrines, setting up fortresses near rivers, camping drainage systems leading downstream, and camping places to avoid swamps and depressions. As a result, Roman soldiers lived on average more than five years longer than civilians, despite long and arduous wars and casualties.

Zhao Hao, who had just escaped from the plague ship, was naturally very aware of the dangers, and the scene of the sick being thrown into the sea often appeared in his dreams. In the future, I am afraid that the days of escape will have to be spent more on ships, and without good hygiene, another outbreak of the plague is not a possibility, but only a matter of time. So he had to get these people in the house to develop a good hygiene habit and maintain a good fighting ability......

"Your Highness, your subordinates will immediately gather people to go and let these people know the rules of the palace." Wang De was secretly happy when he saw that His Royal Highness kept nodding his head, thinking that he could finally show his ability to govern the family, and at the same time, he could also export his evil anger, and volunteered to ask for his life.

"You?!" Zhao Yu paused, and glanced at Wang De again, as if he didn't trust him very much, "It's okay, call Hao Hanlin after breakfast." Then he turned back to the house, and as soon as the sun came out, the stench seemed to be stronger.

"Is there something wrong with Your Highness?" Wang De saw that His Royal Highness did not say anything, but called the doctor, and seeing that he didn't look sick, he asked with half doubts and half anxiety in his heart.

"Where is so much nonsense, just listen to orders!" Zhao Hao frowned and said, he didn't continue to talk to Wang De, who was cold and warm, he still needed to think about how to make these casual people understand not to defecate in the open. This problem sounds small, but the cure is not simple, at least in the world of his previous life, news about these uncivilized behaviors will be exposed on the Internet from time to time, and even cause large-scale debates, and all walks of life have also taken various measures, but there is still no way to completely eliminate them, you can see how deep-rooted this bad habit that has been circulating for thousands of years......
