Jing Er, Alexander and Gongsun Long, gritted their teeth in front of the huge map in the Chengming Palace. In his heart, he really wanted to strangle Yun Yue to death, strangle to death, and strangle again. Anyway, if you shoot for five minutes, you can't understand the hatred in your heart.

But what makes people feel aggrieved is that not only can he not do this now, but he has to stammer. Because of the compelling situation, the six eastern countries carried out another deep-seated cooperation. Great Qin went too far in the first two years, not only invading a large area of Wei State, but even teaching Qi State a small lesson. At the beginning of the war, they had already formed a deep hatred with the people of Chu.

After two years of **** wounds, Han, Zhao, and Wei Sanjin joined forces again. However, this time, he got great help from other countries except Yan. Even the Yan Kingdom was also due to the vigorous lobbying of Prince Dan. Yan Wangxi gritted his teeth and allocated 5,000 war horses to Zhao Guo, which had strong cavalry but a shortage of war horses. It can be said that this is the strongest lineup in the previous joint column. Not only that, but they also found foreign help.

Han Wei borrowed 50,000 troops from the Xiongnu Dadan Yu with a ten-year tax of 20 border cities. And promised that they could be allowed to plunder within the territory of Qin. The Xiongnu Da Danyu, who was tossed by the white plague and had a smoking head, accepted the proposal almost immediately. After receiving the deposit, the army had already crossed the border of Wei.

With the help of the carrier pigeon system, Jing Twenty received the alarm hidden in the high-level of Wei State in a timely manner. At this time, there were only twenty days left before the attack. And their target is the three eastern counties with weak troops.

Surprise attacks are something that every general wants to do, and there is no shortage of examples of successful surprise attacks in history. But the real surprise attack is very difficult, and ancient wars are especially wars in this kind of alliance situation. It is necessary to prepare logistical baggage, and it is also necessary to assemble and organize large armies. The most important thing is that the armies of the six countries of the East are overwhelmingly infantry. They are still stuck in the primitive stage where traffic is basically on the road and the herald is basically on the roar. It will take at least a month to assemble and attack again.

Jing Er saw that the information sent back by Hosaku was a revenant, not because of anything else. It's because the main forces of Great Qin are now in the northwest, and they have just ended the war with Donghu. Great Qin had concentrated almost all the mobile forces at its disposal to Yongdu, and they were exhausted when they walked from all corners of Great Qin's vast empire to Yongdu City. Now, they are all resting in Yongdu.

"The forces of the entire Eastern Front were sprinkled like pepper noodles, and they could not resist the attack of the six nations in any case. Moreover, the eastern front is very long, and as long as the enemy breaks through a little on such a front, the entire defense line can collapse.

Now it is necessary to return the army assembled in Yongdu to the eastern front, and quickly. Yongdu is also hundreds of miles away from the Eastern Front, and the time of twenty days is already very tight. "Alexander is now Jing Er's professional military adviser. He already speaks Huaxia fluently, and it doesn't sound like that weird smell anymore.

"No! They were already very tired from rushing to Yongdu from the Eastern Front, and now they had to rush back from Yongdu to the Eastern Front. Isn't this a toss back and forth? In the battle with the Donghu people, the morale of the army was greatly affected. All told, the casualties add up to almost 100,000. This is not counting the casualties of Yunhou and Yiqujun's subordinates, and the tired soldiers marched thousands of miles again. How can such a soldier fight, and this is not the usage of the Qin army's hard fighting! Although Gongsun Long did not understand military affairs, he could also see the drawbacks of Alexander's plan. That is, the soldiers who were already very tired, and then hurried back to the eastern battlefield, and the soldiers still had some complaints. By the time many soldiers arrived in Yongdu, the Donghu people had already been wiped out. Doing this is somewhat suspicious of tossing.

"I know it's not going to work, so there's a way to hold off. That is to transport 100,000 elite troops as soon as possible to the three eastern counties, which are close to Hangu Pass. It can be attacked and defended, and it is the cornerstone of the entire front. If the coalition forces attack from here, they will be able to reach Hangu directly and cut off the retreat of our army. It can be said that the Eastern Front can be lost, but here it must not be lost. Otherwise, we are in danger of losing the entire existing army in the East. The enemy chose to attack here because he wanted to completely annihilate our main forces in the east in one battle. Alexander took a stick and drew a circle in the three eastern counties.

"From Yongdu to the three eastern counties, the most elite soldiers will have to walk for more than ten days." Although Jing Er didn't understand military affairs, he still knew how many miles he could march in a day. When he was in Yushan Academy, Feng Zheng was a teacher of military classes.

"The slave has an idea!" Qiandu, who had not spoken, suddenly interjected.

"Huh?" Jing Er turned his head suspiciously, it seemed that the words of Qiandu had begun to increase these days. And he is also willing to give himself ideas, and each idea is very suitable. This made Jing Er feel a little impressed by this old waiter.

"My lord, the old slave listened to the conversation between the two gentlemen. There are two key points, one is time, and the other is how to keep the soldiers physically active. The slave thought that the solution was the carriage. The kind of four-wheeled carriage of the Yun family, the Yun family's caravan is now in Xianyang. Their family's four-wheeled carriage could drive from Xianyang through Hangu Pass in just four days. And from Hangu Pass to the three eastern counties, it is much closer. It is estimated that the slave and maid will take about three or four days, which saves more than half of the time, and the soldier's physical strength is not drastically depleted. ”

"That's one way to do it." Jing Er didn't speak, but Alexander opened his mouth first. He had seen the transportation capacity of the Yun family's carriage, and if he squeezed some of them, a carriage could carry more than a dozen people. And the Yun family's caravan is often a few hundred freight carriages with a more super carrying capacity, and it is not a problem to carry twenty people.

"It is not a problem to collect six or seven hundred carriages from the various nobles in Xianyang City, as well as the various yamen and forbidden troops of the imperial court." Qiandu bowed down again and said.

Jing Er's head was running fast, and the mathematical knowledge he had learned at Yushan Academy was now coming in handy. A carriage holds twenty people, and ten is two hundred. A hundred is 2,000 people, and a thousand is 20,000. If you can make four trips in 20 days, you can transport 60,000 people. Coupled with the extremely mobile cavalry, 100,000 people is not a problem at all.

Originally, Yao Jia was sent to Pingliang, nominally to invite Yunyue to participate in the Shangsi Festival. In fact, a new round of negotiations was carried out, and Jing Er believed that the smooth flow of the Modao battalion and the heavy armored cavalry in exchange for the Yun family's trade route was still insufficient. He wanted the kind of oil that could burn from afar. Or, that kind of weapon called a cannonball.

"The flying pigeon sent a letter to Yao Jia and asked him to talk to Yun Hou about calling the Yun family's carriage to transport troops." (To be continued.) )
