If a person is hungry and can't swallow what he chews in his mouth, it must be very sad. Now, the Qin army's chief general, Meng Wu, feels this way.

According to the calculations of the Mo family, in the attack and defense of the city, the ratio of the strength of the two sides is 1:25, that is, excluding the men, women and children who are mobilized to assist in defending the city, one defender on the city can resist the attack of 25 soldiers outside the city, the so-called 100,000 people to attack the city, and 4,000 people to defend the city. There are 6,000 defenders left in Jiyi, a logistics powerhouse, and even if it is a 1:10 ratio of troops, Xiang Yan needs 60,000 people to take it.

It's a pity that the war is not a simple mathematical calculation, Jiyi was lost in one afternoon, the grain, grass, baggage, and vehicles inside and outside the city were all burned out, and even Fuyi could be taken by the Chu army, and the entire logistics and transportation line was completely cut off. After receiving this news, Peng An, the commander of the Qin army, was the first to report to the commander-in-chief: if he did not find a way to keep the logistics and transportation lines unblocked, or collected grain and grass from other places, the Qin army would run out of food after ten days.

100,000 Qin troops, plus 15,000 horses, even with two meals of non-combat standards (0.9 kilograms of millet, 0.54 kilograms of corn), a day still needs 11,700 stone of grain, which is still converted into fine material for the horses to eat, if it is counted as weed, I am afraid it is more than 13,000 stones.

Fuyi to Chengyang cannot be transported by water, only by land. If each of the double-wheeled carts is loaded with 25 stones, it takes 520 carts per day to meet the consumption of 13,000 stones for the whole army; And Fuyi to Chengyang is no less than 200 miles, and it takes three days to reach 60 miles a day, which means that there are 1,560 double-wheel cars full of grain and straw on the Qin Road for more than 200 miles.

There are 1,560 double-wheel carts going to Chengyang, and there must be 1,560 double-wheel carts in Huiyi, and there are at least 3,100 double-wheel carts transporting grain and straw on the Qin road from Fuyi to Chengyang. The horses, coachmen, and various servants along the way and in the barracks were used in the two chariots, and these people (horses) added up to no less than 40,000. If these 40,000 are counted, the daily consumption will be increased by another 2,700 stones, and the daily consumption of grain and straw for the whole army will be 15,700 stones.

When Captain Zhisu said that the grain would be cut off after ten days, it did not mean that the Qin army had the ability to carry the grain for ten days. Ten days' grain was equal to 157,000 stones, and it took 6,280 double-wheeled carts to fit it. More than 6,200 double-wheeled vehicles are more than half of the vehicles transported along the way from Chengyang to Nanyang, the general logistics base

——460 miles from Nanyang to Chengyang, 60 miles a day, and you can reach Chengyang City on the 8th. If we do not include the consumption of servants and horses pulling grain, the army consumes 520 carts of grain every day, and there are more than 4,100 double-wheeled carts loaded with grain along the way, plus the empty cars on the return trip, there are a total of 8,300 double-wheeled carts on the more than 400 miles of Qin Road. In wartime, three meals a day will increase the number of double-wheeled cars by one-third; If we include the consumption of servants and horses, the number of double-wheeled chariots on the road will increase by 5,000 per day.

In the era when there were no sliding bearings, vehicles and special wheels were consumables, and Sun Tzu's so-called 'Qiu Niu cart, six out of ten', is what he said. The Qin army did not have the luxury of leaving one-third of its total capacity in the front-line barracks to pile up grain. Rather than staying in the barracks, it is better to put it into transportation, and 6,200 double-wheeled wagons can transport an additional 11,000 stone and grain per day.

When the Qin army first arrived in Chengyang, there was no grain in the camp, and all the grain was piled up in Jiyi, which was considered safe. The reason why Captain Zhisu said that the 10 days was that in addition to the 5 military rations carried by the soldiers themselves, they also included the 2 days of military rations on the double-wheel cart on the 120-mile road from Jiyi to Chengyang, and the last 3 days relied on local collection near Jiyi and Chengyang. In October, the rice and millet were ripe, and although there were few people in the two places, there were also some millet rice in the mountains and fields, so that the calculation of ten days of grain starvation was obtained. Ten days later, the whole army had to drink the northwest wind.

"What do the Sky Guards think?" The Qin army's big tent, no cadres and others have all retreated, only the main general Meng Wu, the protector Sikong Ma, and the governor Peng An are discussing the issue of grain and straw.

"Xiang Yan occupies the mountain road, and Huyang can't transport grain here, how about Biyang?" Sikong Ma twisted his beard and wanted to let Biyang in the north transport grain.

"This ......" Meng Wu knew in his heart that this strategy was impossible, but he still looked at Peng An, the commander of the Su Prefecture.

"Yu Protector Army: Two hundred and thirty miles from Biyang to Chengyang, one hundred and fifty miles of it is a mountain road, after repair, it is just a graffiti, and it is very reluctant to maintain the grain and straw of General Xin Wu's department, and our army is more than ten thousand, and the daily demand for grain is 15,000 stones, and it cannot be transported by the graffiti alone." Peng An explained, with a worried face.

"Oh......" Sikong Ma let out a long sigh. He understands that the road has three tracks, two tracks, and a single track, which is the type and difference of the road. Because the road is a monorail, it is about eight feet wide, so you need to give way to the car when you meet the car. The plains are fine, the light car can give way to the grass on the side of the road, but there is no way to give way to the car on the mountain road, so you can only wait in a wide place, and the opposite car is coming, and the car can drive over.

"General Meng, what do you think?" Sikong Ma still kicked the problem back to Meng Wu, he was a protector, and he only supervised whether the main general was doing his duty in battle, and there was no obligation to help the main general solve practical difficulties.

"I thought that I could only trap Chengyang and not attack the city for the time being. In addition to returning to the division to recapture the Fuyi Mountain Road, the rest of the troops should join forces with General Xin Wu and attack Yiyi. "Meng Wu patted the map in front of him, and the place he said was a hundred miles northeast of Chengyang, where the Qin-Chu coalition army broke the Wu army back then." In this way, our army can eat in Yiyi before the grain road is opened, and this town is closer to the Wei realm, so it is easy to get the grain transported by the Wei realm, which can temporarily relieve the worry of grain and grass, and can defeat the Jing people who are assembling.

The Jing people gathered in Cai on the east bank of Rushui in the north, and Xi on the north bank of Huaishui in the south, and the two places were only more than 100 miles away from Yiyi. Our army will attack and win, and when the hope of the defenders of the city is desperate, then the city will be attacked again, and the city can be pulled out. Or ......" Meng Wu smiled, and only after laughing did he say: "The Marquis of Qin came to report, the prince of Jing led the prince out of Yingdu to rescue Chengyang, if he can be captured, this battle will be a big victory." ”

"Prince Jing led the king to ......" Sikong Ma was shocked, and then asked: "The general wants to attack Xi County?" ”

"Or attack Xi County, and wait for the opportunity to move after arriving in Yiyi." Meng Wu was not sure.

"Good!" Although the captive king of Chu and the crown prince of Chu would immediately ascend the throne, Sikong Ma still favored Mengwu's strategy.

"If the protector has no objection, the general will be elevated." Meng Wu nodded to Sikong Ma and began to make specific arrangements. The next day, most of the Qin army moved to the north, leaving only 20,000 people to besiege Chengyang, excluding the 10,000 people who returned to help Fuyi, more than 70,000 people joined the Xinsheng army on the north road in Xiaoyi north of Chengyang.

The Qin army did not attack the city and went north, and the defenders immediately reported to the rear urgently with flying messages, and the great Sima Nao, who received the report, did not know the intentions of the Qin army for a while, and when he received the news of the eastward advance of the Qin army on the fourth day, he understood that the Qin army was going to capture Yiyi.

*

"Why did the Qin army capture Yiyi?" In the Yingdu Dasima Mansion, Xiong Jing, who got the front-line military report, looked at the map and asked the others, of course, the others were not Yin Luyangjun of the Mansion, but several members of the Operations Bureau.

"Your Royal Highness, when the first king Zhao was king, the Qin people and our army defeated the brother-in-law of the king of Wu in Yiyi, this place is a plain, suitable for car battles. The Qin people are here, and they are attacking our shortcomings with their own strengths. "After the trial reform of the Great Sima Mansion, the strategists of the Great Sima Mansion, who were idle to the point of decay, had a second spring, and they always rushed to answer questions with slander on their faces.

"False. The Qin people came here to cut off the traffic between Chengyang and then pull out the city while I was not ready. Another clerk spoke. This person ignored the news of more than 70,000 people in the north of the Qin army, and talked nonsense with his eyes open.

"Mr. Li, Qin Jun is good at chariot warfare?" Another staff member wanted to speak, Xiong Jing temporarily stopped him - Cai Bao and others had not fought with the Qin army, and the king of Chu was worried about the attitude of King Zhao and the safety of his son, so he forbade him to go out of the palace to visit Lian Po, so Xiong Jing knew very little about the Qin army in the palace, until he came to the Great Sima Mansion, where there are many old people, and some real things can often be heard in speech.

"Exactly." Mr. Li was quite proud to be questioned by Xiong Jing, and he cleared his throat before saying: "Among the nations, the Qin people have the most chariots, and the Zhao people have the most knights. In the Qin army, the division of the chariot is not the same as the pawn, and often forms a separate army. In the battle of Changping in the past, after the Qin people's 25,000 soldiers broke the Zhao army, there were Qin people's chariot soldiers. Your Royal Highness, the minister thought that the Qin people's chariots and soldiers were marching very fast, and counting the time of the news, I am afraid that the troops were already under the city of Linyi at this time. ”

"The Qin army marched under the city of Linyi so quickly?!" Xiong Jing was startled. What he didn't know was that the news of the Qin army's eastward advance had not yet reached the hands of Da Sima Nao, and Yiyi had already been taken by the Qin army, and Mengwu used not chariots, but cavalry.

"Exactly." What His Royal Highness the Crown Prince said was not exactly elegant words, but fortunately, the meaning of the words was clear.

"Then what does Qin Jun want?" Xiong Jing glanced at Yiyi on the map and was very puzzled.

"Your Highness, the Qin people pulled out Yiyi to prevent the meeting of our northern and southern armies." Mr. Li did not answer, and the other staff members of the War Bureau spoke. "Our army will be in Cai County for one time, and the second will be in Xi County, Yiyi to Cai is only four houses, if the Qin people hold Rushui, it is not easy for our army to cross the water; To the rest of the three rounds, Xi County is in the north of Huaishui, and the Qin people will be harassed when they go south. ”

"What should our army do?" No one speculates as to why the Qin army abandoned Chengyang and advanced eastward, only explaining the benefits and disadvantages of the Qin army's eastward advance. Xiong Jing naturally couldn't imagine that it was Xiang Yan's more than 10,000 people who forced the Qin army to give up the siege and go east to eat, and they were only asking how to deal with it.

"Our army ......" a cadre of staff members are all groaning, Mr. Li said: "Your Highness: The Qin people are fierce, our army should temporarily avoid its front, and take it as the key to defend the city, and wait for the army to assemble before entering the army to fight." ”

"What Section Chief Li said is the best policy." A cadre of staff echoed that the word 'section chief' was extremely awkward.

"What if the Qin State also increases its troops?" Xiong Jing asked.

"Your Highness, the strength of the Qin State is beyond the reach of one country. What I hold is Zhao Wei and other countries sending troops to help. Even if Wei does not send troops, Zhao should send troops to save me, so that Qin is an enemy on both sides, and he will definitely withdraw from our country and return in vain. ”

"But will Zhao send troops......" Xiong Jing said subconsciously, this question made everyone present look at each other. Xiong Jing, as the nephew of King Zhao, asked so, how could they be sure that Zhao would definitely send troops.
