Xiang Yan's proposal made people's blood boil, but the people present were not angry. It is indeed simple to point and draw on the map, but this is a more difficult attack than crossing the sea for 2,500 miles to pull out Linzi, and things will never be so simple.

"Even the cavalry will not have enough food." E Zhuo was the first to object, and he was fully aware of the importance of logistics after five years at the helm of the transportation department. Although, in addition to water and sea transportation, the rest of the supplies in this era can almost only be solved on the spot; Although Xiang Yan would inevitably choose to attack in autumn, and the horses could eat grass all the way to Qin, it was still difficult for him to achieve.

"In autumn, the grassland is fertile and pasture, so don't worry about horse feed." Xiang Yan said. "At first, the soldiers brought grain, and then they could kill horses for food."

"Neither way." Ezhuo still vetoed. "Dare to ask the general, how long does it take for a horse to eat grass? What is the width of the meadure where a horse eats? ”

Ezhuo's question made Xiang Yan stunned, of course, it takes a long time for horses to graze, and it always takes four or five hours. But this is nothing, 30,000 cavalry, one person and three horses, and when they hit Xianyang, they can have half of the horses left, thank God. When a large army fights, horses are already expendable, let alone such a three-thousand-mile leap? As long as the King of Qin is killed, not to mention 90,000 horses, even if all of them are killed in battle, including Xiang Yan himself, it will also be beneficial, and the Qin State will be in chaos for several years or more than ten years because of the dispute between the crown princes.

It's just that Xiang Yan never knew the size of the grassland, because Chu lived in the south, and they all fed horses, and there was no habit of letting horses graze on the grassland. How did he know how much grass a horse would eat?

"The pasture on which a horse eats is more than half an acre. In the meaning of the above general, there are 90,000 horses, that is, more than 50,000 acres of pasture for a day. "Ezhuo Road." If you take the city as a metaphor, the city within a radius of thirty miles is also. There may be grasslands north of the big river, but there is a land in Henan? ”

No one can judge what the situation will be outside the Saiwai until they receive the specific reports from Lu Gao and Lu Tao, or before Li Mu sends someone to come. There is no doubt that there is a large area of grassland north of the Yellow River, but what about Henan to the south of the Yellow River? Further south of Henan, there is Quyan (now Yanchi County, Ningxia) and Baiyu Mountain, what about the aquatic plants here? Now no one knows.

"If not, then strike at it from the upper county, because the food is to the enemy!" Xiang Yan was not a man to compromise easily, and he had never commanded cavalry.

The plan to attack Xianyang in a roundabout way was first proposed by Xiong Jing. The original plan had nothing to do with the war, only with the woman - he wanted to bring Mi Xuan back. Thinking about it later, why not give Qin Guo a guy? Then he sent Lu Gao and Lu Qian out of the customs. Xiang Yan, as the governor of the Great Sima Mansion, was naturally very interested in the plan with the usual plagiarism of the Chu people.

Guanzhong, where Xianyang lived, was the land of Sisai, but the Great Wall of Qin was only on the line from Chaona (now Pengyang, Ningxia) to Fushi (now Yulin Nanyuhe Fort). What is this concept?

The structure of the entire Guanzhong should be a 'day' character. The top horizontal is the Yinshan Mountain Range north of the Yellow River, which is the front line of the Xiongnu and nomads stationed in later generations, so there is the saying of "but make the dragon city fly in, not called Humadu Yinshan". After Yinshan is the Yellow River, the Yellow River may be dangerous in spring and summer, but in autumn and winter, the Yellow River freezes, and the river becomes a thoroughfare, and there is no danger at all.

The second horizontal of the word "day" is Bai Yu Mountain. Baiyu Mountain is the later Hengshan. Most of the wars between the Song Dynasty and Western Xia took place in the Hengshan area. Guanzhong Mountain is like a 'sun', the first horizontal is Yin Mountain, the second horizontal is Hengshan, and the third horizontal is the Qinling Mountains south of Xianyang, which is the natural dividing line between the north and south of China; And vertically, the vertical on the left is Helan Mountain and Liupan Mountain; The vertical on the right is Luliang Mountain. Within the word "day", the Yellow River "several" shape meanders and flows, which is what the world often says about the Hetao.

To the north of Baiyu Mountain is the Ordos Plateau, and to the south of Baiyu Mountain is the Northern Shaanxi Plateau. The former is both a plateau and a prairie, while the latter is a plateau but is full of potholes and folds. Whoever occupies the entire northern Shaanxi plateau will have the strategic initiative in northern Guanzhong. Out of the Hengshan is the flat Ordos grassland, and the Hetao is in full view; Entering the Hengshan Mountains and passing through several inherent river valleys, you can gallop into the Weihe Plain.

In the pre-Qin period, Yidi was not a big threat, and the biggest threat was also effortlessly resolved under the leadership of Qi Huangong. Four hundred years ago, Qin Mugong destroyed the Rong Kingdom for 20 years, expanded the land for thousands of miles, and dominated Xirong. The northwest is not the main direction of Qin's defense, and there are not many dingkou in the north of Baiyu Mountain and the Ordos grassland, and the Great Wall is not far away.

Take the word 'day' as an example, most of the Great Wall is below the second horizontal, which is the northern county of the Qin State (the land of the Yiqu); a small part on the right (about one-third and about one-quarter) is above the second horizontal, and it is repaired to the upper right corner of the word 'day', and above it from west to east, there are Jiuyuan County, Yunzhong County, and Yanmen County of Zhao State, which is the upper county of Qin State.

The two counties of Jiuyuan and Yunzhong are mainly south of Yinshan and north of Hetao (there are also some jurisdictions south of the Yellow River), while Yanmen County is east of Hetao and north of Jinyang, and has nothing to do with Guanzhong. These three counties were all frontiers opened up by King Wuling of Zhao to attack Qin in the south, and his original plan was to go south from the upper counties of Qin, rather than from the Ordos grassland to the south of Baiyu Mountain.

From Shangjun to the south, more than 1,800 li are all Qindi, although the cavalry can march quickly, but Xianyang has sufficient warning time. It is estimated that the army has not yet arrived in Fushi, and Xianyang has already put the whole city on alert.

Different from the legends of later generations, Xianyang has a city. Xianyang city is in the north of Weishui, after several expansions, the city circumference has been eighty miles. In later generations, due to the continuous northward movement of the Weishui River, a large section of the city foundation was washed away, but many city foundations were still left. Because Xianyang, which is eighty miles away, was first built more than 100 years ago, no matter how much the regulations are expanded, they cannot catch up with the prestige of the Qin State to dominate the world.

Therefore, when the king of Zhaoxiang, the Qin State built a palace in the south of Weishui, the so-called non-magnificent is not majestic, the Zhangtai Palace that received the envoys of the countries was extremely magnificent, Qin destroyed the Eastern Zhou Dynasty, and Jiuding moved to the Zhangtai Palace. It's just that no matter how magnificent Zhangtai Palace is, it is also outside Xianyang City. Not to mention that Zhao Zheng's residence in Weinan and Weibei is uncertain, even if Zhao Zheng handles government affairs in Weinan every day, once there is a policeman, he will retreat to Xianyang City in Weibei.

The plan he made was to move south from the Ordos grassland, along the Yellow River to the west of the Hetao, and enter the Qin State from Beidi County. Here to Xianyang is only more than 700 miles, if it goes well, you can reach Xianyang in three days by horse. Regardless of whether the mount is dead or alive, it can be there in two days. Even if Qin Jun had a flying message, the news was not very detailed. First, a small force crossed the border to attack and harass, giving Xianyang an illusion that it was just a Rong people crossing the border, and when it relaxed, the army broke through to the north bank of Weishui, and maybe Zhao Zheng could be intercepted and killed in Weinan.

The more than 700 miles of running was not too difficult, and the real difficulty was how 30,000 knights and 90,000 horses could reach the outside of Northland County safely. Is this really how you eat grass all the way? 30,000 soldiers half on grain and half on horse meat to satisfy their hunger?

"How does Eqing think it is to the north of Beidi County, outside the Yanshi Fortress?" The scene was cold for a while, and Xiong Jing asked.

"The minister thought that he had traveled three thousand miles for this, and it was mostly a barren place, and it was very difficult to attack Qin." E Zhuo didn't look at Xiang Yan when he spoke, he felt that Xiang Yan wanted to kill the Qin people and wanted to go crazy. Even if Xiang Yan is already a marquis, you don't need to look at his face when you speak.

"Don't you know how difficult it is, don't you just ask Eqing if he has a good plan?" Xiong Jing asked.

"Ugh." E Zhuo was also stunned when he saw Xiong Jing, sighed and finally said: "The minister thinks that the horses should have twelve catties of wheat every day, and the rest can eat grass." Otherwise, they only eat forage, which not only delays the journey, but also causes many horses to die and have no horsepower. ”

"Twelve pounds of wheat a day?" A dry man smacked his tongue. Twelve catties is Chu catties, that is, three kilograms. Horses eat three kilograms of concentrate, and they have to eat about six or seven kilograms of forage, otherwise they can't eat enough at all.

"Yes, yes." Ezhuo Road. "There is no refined grain, there is no horsepower; They only eat forage, and many horses die. ”

"Every 100 miles a day, each horse needs to carry 90 kilograms of wheat?" Xiong Jing asked.

"Definitely. The minister thought that he should use a four-wheeled carriage. E Zhuo said again: "Six horses set of cars, each car can carry 1.5 tons when the road is broken." 60,000 horses can have 10,000 cars, that is, 15,000 tons. ”

"Huh?!" Xiong Jing gasped, 10,000 four-wheeled carriages!

Everyone was stunned, but Ezhuo hadn't finished speaking. "Ninety thousand horses need two hundred and seventy tons of wheat a day, and thirty thousand soldiers need thirty tons of millet a day, that is, three hundred tons, and fifteen thousand tons will travel for fifty days. Sixty miles, or three thousand miles, are traveled every day. However, the army needs to be fed to the enemy because of the Qin, and if the Qin people clear the wilderness, the ministers will be helpless. ”

"Now that you have entered the Qin State, what about the four-wheeled carriage?" Xiang Yan's frowning brows finally relaxed.

"In order not to let it fall into the hands of the Qin people, it should be burned." Ezhuo Road. 10,000 four-wheeled carriages are worth more than one gold in just four hubs, and 10,000 carriages are burned, which is equivalent to 20,000 gold in vain.

"Horses die less, and 30,000 horses can be returned to Yan's Clan." Lu Yangjun interjected that he agreed with this policy. "The bronze bearings of the carriage can be brought back with the horse. However, there is no road outside, and the carriage is not ......"

"Yes." I nodded naturally. "There are grasslands outside the plug, the grasslands are flat, the six-horse carts, and the roads are bad. In the past, the Rong people attacked me, and there were also Rong cars. ”

"What about the road outside the plug? Is the grassland flat? What is the geometry of the six-horse carriage? Try it all. E Zhuo just said what he envisioned. This is a plan within the Great Wall, just moving outside the Great Wall.

"There's no urgency." Li said. "After this attack, Qin Ruo will attack Zhao again, and four years later, he will attack Qin. In the previous three years, it was possible to test the plug, build a carriage, train soldiers, explore Qindi equipment, and Xianyang virtual reality. ”

The plan was long-term, and it was not until the second attack of the Qin army against Zhao that it attacked Qin, which was four years later. Xiang Yan was not satisfied with this, he said: "If the Qin people don't withdraw next year, Chu Qi doesn't save Zhao, and he will be out of the fortress in two years." ”

"The Qi people are willing to send cavalry to attack Qin?" Lu Yangjun didn't understand.

Xiong Jing smiled at this: "Out of the fortress to attack Qin, the cavalry of the Qi State, the cavalry of the Wei State, and even the cavalry of my Chu State are all the cavalry of the Zhao State. ”
