Youzhou and Yanjin, this port at the intersection of rivers and seas, is a new city that flourished with the navigation of Yongji Canal. Now it has become overcrowded with the settlement of a large number of outsiders.

The troops gathered in Yanjin were stationed outside Yanjin City. The camps of each army were connected into pieces, and the camps were like houses. From a distance, people just mistakenly thought that the size of Yanjin City had increased several times in an instant.

Thanks to the opening of the Yongji Canal and the transportation capacity of the steamship, a large number of troops and materials arrived in Yanjin in a relatively short time via water. Marshal Yuwen Weihan was very satisfied with this, but he did not dare to take it lightly.

It was morning, and he took his assistant to inspect a military camp outside the city. After entering the camp, the first thing he saw was the toilet. He wanted to see with his own eyes whether the military camp was handling human and animal excrement correctly. If he did not do enough, he would have to change it immediately.

In Yanjin area, there are many military camps within a radius of dozens of miles. Every day, people eat horses and consume a lot of food and grass, and also produce a large amount of excrement. If these excrements are not properly treated, they will pollute the water source or the ground of the camp, and it will easily cause plague over time.

The more people there were in the military camp, the more people died when the plague broke out. Yuwen Weihan didn't expect that more than half of his casualties had been killed before he even landed on Liaodong.

When he came to a row of straw sheds, he walked around and did not go into the compartment to check. This was done by the military officer. Yuwen Weihan wanted to see whether the toilet was normally connected to the biogas tank and whether the "underground" biogas tank was normal to "gas".

During the march and war, the excrement produced in the camp is usually concentrated in several long pits, and after leaving, it is buried on the spot, or it is ignored at all. This has been the case since ancient times, but now, it can be used to use biogas tanks to "use waste" of feces and other excrements.

In the various military camps in Yanjin, when the troops and horses were still on the way and the camps were built, they had already dug up the biogas pools. When the army settled in, the excrement of people and horses would collect the biogas from these biogas pools. The biogas generated was directed from the pipeline to the biogas stove in the distance, and then ignited and played a role.

The biogas stove can boil water and cook, saving considerable expenses for firewood for the military camp. The feces processed in the biogas tank, including various insect eggs, can be sold to farmers for fertilizer fields after being killed.

One truck of feces, two trucks of water, and three trucks of feces are mixed into three trucks of feces, and sold as a commodity, and the income will be immediately available.

The merchants who hired people to farm around Yanjin were big buyers of manure and water. The reason why these merchants hired people to farm in Yanjin and even Youzhou was to "open up" and use the grain obtained from the farm to exchange salt for the government in Youzhou for the salt.

When merchants got the salt inlet, they went to Changlu Salt Field to mix salt nearby, loaded ships, and sold them to the Yongji Canal coast. The transaction is now very prosperous, and more and more merchants are hiring people to farm in Youzhou, so the large amount of feces produced by the military camps in Yanjin will not worry about the lack of sales.

There are so many people and horses in the military camp, and the large amount of excrement produced daily by them, which was originally a serious source of pollution, but now they have become a source of wealth. Not to mention profit, at least the cost of building a biogas tank will be left after taking back the cost. If the army stayed for a longer time, the income from selling feces would be greater.

Thinking of this, Yuwen Weihan felt a little moved that building a biogas tank "turned waste into treasure", a method that is not available in military books.

After Yuwen Weihan checked the toilet and biogas pool, it was already noon. He moved to the camp stove and watched the soldiers lined up to get food, and then asked the entourage to make an extra serving. He wanted to try it himself and see how the food was.

Generally speaking, the people eat two meals a day, namely "morning food" and "night food". The same is true for the army. Now, in order to boost morale, the troops gathered in Yanjin have implemented a three-meal meal system.

The morning food remains unchanged. Eat one meal at noon, which means "lunch food", and the evening food is delayed until sunset.

Three meals a day are to make the soldiers eat enough and keep up with their physical strength when marching and fighting.

In order to prevent people from deducting their diet, using inferior food as good ones and using inferior food and fruits and vegetables to fool soldiers, Yuwen Weihan thought of many ways to supervise. Eating the same pot of food with the soldiers is one of the best ways.

If anyone dares to tamper with food, he will be caught soon.

The food that is eaten alone is not good. The water that the soldiers drink must be boiled, so it is strictly forbidden to drink "raw water" in the military camp, and they must drink the "cooked water" provided by the military camp.

Boiling water is more troublesome, but this issue has no discussion. Yuwen Weihan repeatedly emphasized this point when convening the main generals to discuss the matter.

It’s not that he is pretentious, but that it is indeed necessary. If this is not the case, the combat effectiveness of the army cannot be guaranteed.

During this eastward expedition, the troops from the expedition came from many places, including Hebei, Henan, Lianghuai, Shannan, etc. Soldiers from different regions, who were in different places, would inevitably face the problem of disagreement in the local environment.

This problem can be very mild. The soldiers may be relieved after a while because they are not accustomed to the environment and may be just gastrointestinal discomfort;

This problem may be very serious. The soldiers were not accustomed to the environment, vomited and diarrhea, fell ill in bed, fell dying, and even died of illness.

No matter what the situation is, it will affect combat effectiveness. This problem has troubled the generals leading troops since ancient times, and they can basically rely on their own physical fitness to handle it.

Leaving the will of fate, this is not the correct attitude of a general and a soldier in a war. When marching and fighting, you must be familiar with the terrain. If you are not familiar with the terrain, you must find a way to find a guide. The problem of being unacceptable to the local environment must also be solved.

The method is very simple, that is, drink cooked water (boiled water).

Years of practice have shown that when the army marched and fought, the soldiers insisted on drinking cooked water can effectively alleviate the situation of unacceptable conditions in the local environment and effectively reduce the chances of the soldiers' illness.

This approach has "scientific basis".

It is said that a large number of "bacteria" survive in the human stomach and intestines, and these biological settlements that are invisible to the naked eye are "fungal groups".

As the "indigenous people" in the stomach and intestines, these "fungal groups" maintain the normal operation of the stomach and intestines. When there is a problem with the "fungal groups" (large deaths, or changes in bacterial species), the human gastrointestinal function will be disordered, and the symptoms shown are gastrointestinal discomfort and diarrhea.

The so-called "failure to adapt to the environment" should be that a person goes to another place. After drinking local water, the "local bacteria" in the water enters the stomach and intestines and in a "fighting battle" with the original "fungal flora", which causes gastrointestinal dysfunction.

After the "fungal flora" in the stomach and intestines stabilize, the human stomach and intestines return to normal. This is the reason why it will be better after the weather is not adapted to the local environment and the environment will be relieved for a period of time.

Therefore, if you want to overcome the lack of adaptation to the environment, the solution is to drink the boiled "cooked water" because the bacteria in the water are killed by the high temperature.

This can also prevent the soldiers from drinking unclean raw water and causing the disease.

This "scientific basis" was said by my father. It sounds mysterious and Yuwen Weihan doesn't really believe it.

However, my father led his troops for many years and fought south and north. He insisted on drinking cooked water in the army, and never had a large-scale situation of disagreement.

The officials in the southern middle and the officials in the Liaodong also insisted on drinking cooked water, but there was no large-scale disagreement in the local environment.

When Yuwen Weihan led his troops, he insisted on letting the soldiers drink cooked water. There was no situation where the soldiers' combat effectiveness declined due to the large number of unacceptable conditions.

Facts are better than words. During this expedition by the government army, Yuwen Weihan issued a military order that the soldiers of the army must drink cooked water unless they had to.

As a marshal, he had a lot of things to be busy with, but he worked tirelessly. In order to deal with the problems of excrement and diet, he wandered around the military camp. It seemed a bit "unemployed", but in fact it was to ensure the combat effectiveness of the army.

To win a battle, and to use your brain to deploy troops and to care about the suffering of soldiers, you must care about the suffering of soldiers. If you care about the suffering of soldiers, you must care about the realm. The problem of unacceptable land and land is not solved, and the expeditionary force with hundreds of thousands of troops collapses only in the evening.

The imperial army should not be defeated in Liaodong due to the lack of adaptation to the local conditions and conditions.

This is the precautions my father repeatedly reminded him in his letter, and Yuwen Weihan deeply agreed.

He was full of energy while eating simple meals and looking at the soldiers around him with different accents.

It is January of spring, the weather is cold and the coastal waters are still frozen. It will not be until early February that the ice will begin to melt. Then the ice breaking operation will have better results and then sea transportation will begin.

It is not impossible to go to Liaodong by land, but it consumes too much along the way, so it is not the first choice for this Eastern Expedition.

Therefore, the troops gathered in Yanjin, Youzhou and Huangcheng, Laizhou, need to be stationed in the assembly area for a period of time. The soldiers must make preparations before the war, and the generals of each unit must work together to deduce the chess piece and be familiar with the battlefield terrain.

Familiar with tactics and determine tactical goals at each stage so that you can fight together and achieve final victory.

Thinking of this, Yuwen Weihan was a little excited. He had been preparing for the Liaodong Battle for nearly ten years, doing countless exercises, and even personally led his troops to Liaodong for "internship".
