The supply efficiency of the Eastern Front was inseparable from the horse-drawn carriages, tracked transporters, and steam locomotives that Adrian had made the supply triumvirate.

Among them, only the crawler transporter needs to use a trendy energy supply, which is gasoline. During this period, the use of gasoline was not large, mainly because the penetration rate of automobiles was not high, and there was a lot of inventory, so Adrian's tracked transporter could operate smoothly at the beginning. However, as the use of tracked vehicles became more frequent, the amount of gasoline in reserve dropped rapidly and was close to exhaustion.

When something is running out, you will think of buying, saving, and finally mining. The reason is that it is the most convenient and fast to buy, saving is a last resort, and the final mining is something that everyone is unwilling to do, mainly because it is time-consuming and laborious, not to mention, it is difficult to get the expected results. As far as Germany's current situation is concerned, there is no need to pay too much attention to purchases, and Mo said that Britain has no economic blockade, even if it is open for Germany to buy, there may not be much. In 1915, oil extraction and refining were still in a very primitive period, and the reason why Carl Benz developed the first engine using gasoline as fuel was because gasoline was a waste product at that time, and it was extremely cheap, so Benz, who was not wealthy, could use it for experiments. Although the status of gasoline has improved due to the advent of automobiles, its oil exploitation has not yet made great progress, and it will take more than ten years to improve if this historical development continues. However, with the outbreak of World War I, the amount of oil used by the participating countries and a few oil exporting countries showed an explosive increase, and the main effect was the increase in the number of cars used for transportation.

At the beginning of 1915, Britain had put 100,000 cars into the Western Front in Europe, and France had produced and imported 80,000 cars from more than 100 cars at the beginning of the war in just one year. On the other hand, on the German side, less than 100,000 cars were put into use on the Western Front, and more than 1,000 tracked transporters were put into use on the Eastern Front battlefield, and the rest relied on horse-drawn carriages with wide wheels to undertake transportation. The reason why supplies can be guaranteed even when there are not many means of transportation is that Adrian uses the space and the return journey without wasting any strength. For example, a general horse-drawn carriage assumes the role of transporting the wounded and light supplies unless the tracked transporter is in short supply, while the tracked transporter will give up the task of transporting heavy military supplies when the carriage is not sufficient, and temporarily serve as a transshipment task. When the weather improves, or when the road allows, the tracked transporter will add a carriage to take on more transport tasks, which is not something that livestock can do.

Adrian had already started to exploit oil wells when he embarked on the tracked truck project, but unfortunately Germany's natural resources were as poor as beggars, lacking everything, and oil was the first few households in need. Nor does he seek to exploit large tracts of oil fields, as a few wells can secure his convoy. As for the lack of oil elsewhere, what does it matter to him? I don't have the mentality of victory... Regardless of whether he has the ability or not, even the current situation cannot be won if the war continues. Due to the blockade of maritime trade, Germany imported materials all relied on the transshipment of remote and small countries, not to mention slow, the efficiency was terrible, and the quantity was pitiful.

On the other hand, the major powers such as Britain and France on the side of the Entente were able to obtain a steady stream of supplies in the hands of the United States. As the debt changes, when the United States becomes the largest creditor of Britain and France, it will not see Britain and France lose, and it will inevitably ensure the victory of Britain and France, and it is not certain that the United States will definitely enter the war, but Germany has no hope of winning. It is so difficult to fight Britain and France, not to mention that the United States, which is already at a new peak, has fully activated industrialization.

Seeing that the gasoline reserves were about to run out and there was no news about the oil, he was more anxious than anyone else, but he didn't dare to tell anyone, otherwise it would cause unnecessary panic. People are like this, they are used to eating 3 loaves of bread a day, and one day when you tell him that there will only be 2 loaves of bread in the future, it is strange that they are not anxious with you. Fortunately, he is not a person who gives up easily, otherwise he would really pick his son and leave.

Adrian, who is a traverser, of course, knows about coal liquefaction, but the current situation is that coal, ethane, and ethanol are all in short supply, although there are already such projects, but the output is simply not enough. One is the civilian power and the other is the national power, and the two cannot be mentioned at all, unless Adrian is allowed to control the whole situation. For the first time, Adrian reached a level of mad craving for power.

Although Adrian, who had not slept all night, did not come up with any good solution to the problem of the internal combustion engine's urgent lack of fuel, he thought of a way for himself to walk in the future. The people's mental outlook has taken on a new look, and the people who can see the command post are inexplicable, have they thought of a way?

He ordered the soldiers to take a copy of the encrypted telegram to the Eric group in his own name, the encryption code that even the telegraph operator had never seen, except that he understood a line of greeting in a generic code, Dinah Eugene Sylna. After that, he rushed to the base camp of the Eastern Front and made a private appointment with Hindenburg.

When Sylna, who was far away in Berlin, received the telegram, she hurried back to the manor, turned out a thick book, and began to translate it on her own. Because it was multiple encryption, and it was also the first time that Sylna had actually translated this kind of encryption code between the two, it was not very efficient, and it was not until late in the evening that the last word was written. Regardless of the fact that it was already night, she used the convenience of her identity to successfully pass the night ban and return to the office building of the Eric Group in Berlin, and urgently recalled some personnel to hold a meeting overnight to discuss. It was not until noon the next day that the crowd dispersed.

At the end of the meeting, an officer appeared in Shirna's office with a briefcase and handed over the documents in duplicate, signed them, and took one of them before leaving.

"It's too little, I don't know if it's in time." Sylna said, looking at the contents of the paper.

It was a list of items provided by the military, including steel and other supplies that were in short supply throughout the empire. This was the first time Adrian approached Hindenburg and asked him to write a letter asking for something, all of which were taken from other people's mouths.

Workers at one of the Erik Group's factories in Dresden are more energetic than usual today, because their foreman says that their wages will be doubled in the next four weeks, which makes them happy for a long time and that they can buy more food again. But at the cost of a horrible 12 hours of work, working two shifts. This has never been the case in Eric's group. Although there is no explicit rule that the working hours are 8 hours a day, Adrian has always been arranged according to the 8-hour work schedule.

With the factory in Dresden working overtime, new machines, new equipment, and new large trucks are coming from the factory directly to their destinations.

In September 1915, with the transfer of Field Marshal Mackensen to the Balkans, a new offensive was launched against Serbia, and on 7 October he commanded the German 11th Army and the German-Austrian 3rd Army to launch a psychological offensive against the numerically inferior and war-weary Serbian army. On October 9, Belgrade was successfully taken. The crisis in Serbia was completely remarkable, and the situation in the Balkans suddenly changed dramatically. Britain and France, fearing that the Allies, who had lost their grip on one side, would continue to hold their forces on the Western Front and sent emissaries to Romania to seek entry into the war.

Major General Adrian, who was the chief of logistics on the Eastern Front, was only responsible for the supply of the German army for the entire operation, and did not help the Austro-Hungarian army at all. Although Mackensen and the Austro-Hungarian generals had a strong opinion on the matter, they did not show it. After all, during the Battle of Gorlice, Adrian had no spare energy to help the two countries obtain good logistics.

In fact, they don't know that some of Adrian's fuel reserves have bottomed out, and they simply have no ability to do good deeds, and the coal liquefaction project to expand production has just begun, and the production capacity still cannot play a decisive role. Even the supply of the entire Eastern Front has been adjusted to the fourth rank, and this situation is still very tense. If it really comes to the situation of fifth-class supplies, Adrian will not be dismissed, and he will not have the face to stay any longer.
