Knowing the crisis they were facing, both William and Emperor Joseph went mad, and all the troops they could find were loaded onto trains and ships, and they poured along the railroad and the Danube to Romania without stopping. However, it is clear that it takes more time than the Russians, who are only 400 kilometers away from the sea, and who have already assembled and prepared countless merchant ships, who have to be recruited from all over the world, and even mobilize reserves.

Especially the German army, they have to travel close to 2,000 kilometers, whether the Dro coalition forces on the Danube line can wait for them, I am afraid can only depend on the will of God, although there is a German army and a Romanian army group, but the latter is completely a bunch of old, weak, sick and disabled pieced together, this small country with a population of only a few million, has mobilized three army groups for this war, and has suffered heavy losses in the early stage, you can imagine what their second-line troops must be.

The hundreds of kilometers wide Danube defense line is full of dangers, and it is fortunate that this large river is blocked, otherwise the Russians would have hit Bucharest a long time ago. A large number of 155-millimeter heavy guns purchased from China were lined up on the east bank, and the overwhelming shells kept smashing on the heads of the Droz coalition troops, and the yellow poisonous fog of mustard gas and Louis gas filled the smoke and fire of the explosion, and the gray cattle carrying various tools for crossing the river frantically rushed to the surface of the Danube, rowing to the opposite bank with dense bullets and shells, and then the pieces were overturned in the river water, and the blood stained the Danube red, but the follow-up was still constantly invested in this huge meat grinder.

The Russian troops who landed on the shore were even more in the sound of Ula's slogans, while pouring vodka, while sacrificing their lives to attack the positions of the Dro coalition army, and in some places, large-scale white-knuckle battles broke out between the two sides.

And to the north, the situation was exactly reversed, and the Drowe coalition army, led by Baron Golz himself, was in the same way. Risking his life and death, he attacked Brusilov's blocking position.

In order to support the Romanian battlefield, William even transferred the air fleet that was originally going to bomb London, and these aerial monsters full of bombs poured death over and over again towards the Russian positions, and even used large-caliber machine guns to fire when the bombs ran out. Not only airships, but also airplanes have joined the battlefield, and these small toys made of wood and canvas also use machine guns and hand-thrown mortar shells to attack the Russian army.

However, such an attack, placed on a battlefield of nearly a million people, is simply like throwing a few small stones into a torrent. At most, it was just a small splash, and it had no substantial impact on the battle situation.

However, the Austro-Hungarian Danube Fleet came down from the upper reaches of the river, which greatly relieved the pressure on the Dro coalition forces, and these large and small river gunboats used their cannons to bombard the Russian troops crossing the river with their cannons, and almost turned the tide of the war for a time, but soon the river gunboats of the Russian Black Sea Fleet also drove up from downstream, and the two sides directly launched a major battle on the course of the Danube, and the Austro-Hungarian gunboats, which were small in tonnage but more flexible, and the heavy but fierce Russian gunboats fought on the Danube, which was only less than 500 meters wide. Even part of the army artillery joined the battle between them.

In short, the entire Danube defense line has completely entered a white heat, and almost all the means available to both sides have been used, although for the time being, the defenders of the Derog coalition army can still hold it, but the shape is not optimistic. Especially on the Dniester front, the three armies of the Russian army also launched a large-scale offensive at the same time, and Baron Gorts, who was attacked by the enemy on his back, had a more and more difficult time.

Fortunately, this old fellow was cunning enough, and he armed a large number of local Romanians in Bessarabia. These militias were a good complement to his front-line attrition, but it still did little to help if the German-Austrian reinforcements didn't arrive sooner. Both of his lines were in danger of being breached.

"Alas, you said that this Goltz was a leader among the German generals of his generation, why is his head still so rigid, why doesn't he play such a good card in his hand?" Emperor Yang of the General Staff of the Army in Beijing lamented while looking at the map.

He was very concerned about the war situation in Romania, and to be honest, even he didn't expect that with the brains of the Russians, he would be able to do such a beautiful job, and almost immediately forced Germany and Austria to the edge of the cliff. And judging from the current situation, the Russians really have hope of success, in the short term Germany and Austria will not be able to mobilize enough troops to put into the Romanian battlefield, the current armies of both countries are locked on various fronts, and no group army can be drawn, the only way is to form a new army, but even if the new soldiers are called up in the short term, it is impossible to put them into the battlefield.

The Russians were different, Nikolai had enough troops in his hands, and even if he kept filling the Danube with the lives of gray cattle for the next moment, it would be enough to fill it, as long as he crossed the Danube, even if he could not enter Serbia next, as long as he took the Ploiesti oil fields, it would be considered a success.

But in this case, Yang Feng will not have to play next, he still expects this oil field to provide a steady stream of incendiary bombs to William, not to mention that once the Russian army breaks through the Danube defense line and hooks up with those Serbian guerrillas, it is really possible to enter Serbia, and at that time, I am afraid that I will not be able to help but attack Austria-Hungary, and the defeat of the Allied bloc can be said to be doomed.

"What do you mean?" Li Yuncong said cautiously.

"What do Romanians have?" Yang Feng glared at him and said.

"Oil!" Li Yuncong said inexplicably.

"How did we play in Vietnam last time?" Yang Feng said.

"You mean pouring oil into the Danube?" Li Yuncong's head buzzed, and he immediately understood how to solve the predicament in Romania, the Ploiesti oil field has an oil pipeline directly to Bucharest, and there is also a branch to the Danube port of Jurju dozens of kilometers away, and there is no need for transportation, just open the valve and pour it into the Danube, it is already late autumn, the Danube River is the dry season, and the flow rate is gentle on the great plain of eastern Romania, which is very suitable for doing this work.

This oil field produces tens of thousands of tons of crude oil every day, and it doesn't take much more, and the Russians are stupid to pour a day's production capacity into the Danube, their inland river fleet on the Danube has no other choice but to escape, Brusilov can indeed fight, but the problem is that his logistics and supplies all depend on this fleet, and without supplies, his tens of thousands of people can't even last a day, not to mention that once the crude oil is ignited, Kuropatkin, who is attacking, will have to obediently hide aside, and then this battle will not be able to fight at all.

What's more, as long as the production of the Ploiesti oil field does not stop, you can pour as much crude oil as you want into the Danube, and if you get angry, you can pour it directly for a month, not to mention the Danube, even half of the Black Sea is over, and no one dares to approach the entire Romanian coast after the fire is lit.

"That's a ruthless trick." Thinking of this, His Excellency the Chief of the General Staff looked at the emperor's eyes full of infinite admiration. But the problem now is that Emperor Yang thought of it, but the Germans couldn't think of it.

"Settle the problem yourself, and in any case transfer this method to the Germans in a reasonable way." Yang Feng said with a straight face.

Li Yuncong's eyes rolled, he picked up the phone and dialed his home, and then the housekeeper who answered his phone said: "Go, prepare some invitations, just say that I will hold a dance at home tonight to celebrate the birthday of the Seventh Lady, doesn't she have a good relationship with the German minister's wife, and even the German minister's wife is invited together!" ”

Six hours later, the German minister Hai Jing listened in a cold sweat to his wife's relays of the story of the chief of the general staff of the Chinese Army, who invited her to dance at the ball, and showed off the story of forcing tens of thousands of French troops to drop tens of thousands of French troops with 12,000 tons of crude oil in Vietnam.

Of course, he understood that Li Yuncong was reminding him or the German government that the Romanian front could also pour oil, and this guy immediately sent a telegram to China without the slightest hesitation. William, who was scratching his ears and worrying about how to solve the Romanian dilemma, was stupid when he received Haijing's telegram, and his rigid traditional brain really didn't think that he could play like this.

Immediately after that, this telegram was handed over to Count Schlieffen, who immediately took it to the General Staff as if he had found a treasure, and then summoned the staff officers with Moltke Jr. to study the feasibility of this plan, out of the rigorous style of the Germans, these staff officers after careful research and even deduction, including the speed of the Danube, the flow of the Danube and other aspects of the data investigation, finally determined, in addition to bringing an ecological disaster to the people of Romania and even the people of all the countries along the Black Sea coast, This plan can be described as perfect militarily.

At present, the predicament of Droz's coalition army can be lifted in an instant, and not only that, but it is even possible to win a huge victory if it is done well, at least the army under Brusilov will not be able to escape.

Since there was nothing to say about this, soon a detailed plan drawn up by the General Staff of the German Army was sent by telegram to Baron Golz and King Carol I of Romania at the front, and the two guys, who were being pressed by the Russian army, agreed to the plan without hesitation, and immediately began to prepare for its implementation.

First of all, the time and the direction of the wind must be chosen, once the fire is lit and burned, it is not good, the Austro-Hungarian fleet on the Danube must withdraw to the upper reaches, it cannot do this work during the day, it can only be carried out at night, in addition, due to the flow rate, it is necessary to prepare a number of ignition points, and some defenders near the shore must also be prepared to retreat, in short, there is still a lot of work before the implementation of the plan.

And it is different from what Yang Feng imagined, it is not possible to pour oil only from the oil pipeline in the port of Zhurzhu, the flow rate is too slow, and it takes four days to reach Brusilov, but it can be pulled directly by train to the Danube River to pour oil, and one and a half days are enough to arrive, and the Ploiesti oil field is still in production, and it is enough to pour production there.
