If a person is hungry and can't swallow what he is chewing in his mouth, he must be very sad. Now, the Qin army commander Meng Wu feels like this.

According to the Mohist calculations, in the attack and defense of the city, the strength ratio between the two sides is 1:25, which means that the men, women, young and old mobilized in the city to help defend the city. A defender on the city can withstand the attack of twenty-five soldiers outside the city. This is called a 100,000 attack on the city and 4,000 defenders. There are 6,000 defenders left in Jiyi. Even with a strength ratio of 1:10, Xiang Yan still needs 60,000 to take it down.

Unfortunately, war is not just mathematical calculations. Jiyi was lost in the afternoon. The food, supplies, and carriages inside and outside the city were burned out. Even Fuyi might be taken down by the Chu army, and the entire logistics transportation line was completely cut off. After this news, Peng An, the chief commander of the Qin army, was the first to be anxious to the chief general: if he did not find a way to keep the logistics transportation line open, or search for food and grass from elsewhere, the Qin army would be out of food in ten days.

The 100,000 Qin troops, plus 15,000 horses, even if they were not a combat-standard meal (0.9 kilograms of millet, 0.54 kilograms of millet), they still needed 11,700 stones of grain and fodder a day. This was to convert the straw chews eaten by the horses into essential materials. If they were to use straw chews, it might not be more than 13,000 stones.

It is impossible to transport water from Fuyi to Chengyang, so it can only transport land. If the double-shaft chariot is loaded with twenty-five stones per chariot, it will take 520 cars per day to meet the cost of 13,000 stones of the entire army; and if Fuyi to Chengyang is less than two hundred miles away, it will take three days to arrive every day, which means that there are 1,560 double-shaft chariots loaded with food and fodder on the Qin Road more than two hundred miles are being transported in a intensive manner.

There are 1,560 double-axle chariots to go to Chengyang, and then there must be 1,560 double-axle chariots to return to the city. On the Qin Road from Fuyi to Chengyang, there are at least 3,100 double-axle chariots to transport grain and fodder. The horses, coachmen, various servants along the way and in the military camps used by the double-axle chariots, the total number of these people (horses) is no less than 40,000. If these 40,000 will be added, the daily consumption will be added to 2,700 stones, and the entire army consumes 15,700 stones of grain and fodder every day.

The commander of the sour commander said that the food was out of stock ten days later, which did not mean that the Qin army had the ability to carry the food and fodder for ten days. Ten days of food and fodder was equal to 157,000 stones, and it required 6,280 double-axle chariots to be carried. More than 6,200 double-axle chariots exceeded half of the transport vehicles along the way from Chengyang to Nanyang, the general logistics base.

——Four hundred and sixty miles from Nanyang to Chengyang, travel 60 miles a day, and you can reach the city of Chengyang in eight days. If the servants do not include the servants, the food and horses consumed, the army consumed 520 trucks a day, and there will be more than 4,100 double-axle chariots loaded with food and fodder along the way. In addition, the empty trucks return, there are 8,300 double-axle chariots on the Qin Road for more than 400 miles. During the war, the number of double-axle chariots will increase by one third; if the servants do, the consumption of carriages and horses will increase by five thousand double-axle chariots on the road every day.

In an era when there was no sliding bearing, vehicles, especially wheels, were consumables. The so-called "Qiu Niu Cart, 60% of the tenth" was what my grandson said. The Qin army had not been too luxurious to leave one-third of the total capacity of the double-axle chariot in the front line of the military camp to pile up food. Instead of staying in the military camp, it was better to put it into transportation. Six thousand two-axle chariots could transport an additional 1,000 stone of grain every day.

When the Qin army first arrived in Chengyang, there was no accumulation of grain in the camp, and the accumulation of grain was piled up in Jiyi, which was considered safe. The reason why the commander of the millet commander said on ten days was that in addition to the five-day military rations brought by the soldiers themselves, the two-day military rations on the double-rod chariot on the 120-mile road from Jiyi to Chengyang was included. On the last three days, he relied on Jiyi and was collected on the spot near Chengyang. In October, rice and millet were ripe. Although there were few people in the two places, there were some millet and rice in the mountains. This was the calculation that the food was cut off on ten days. Ten days later, the entire army could only drink the northwest wind.

"What do you think the Sikong Guardian?" The Qin army's big tent, no one else had already retreated, and only the chief general Meng Wu, the guardian Sikong Ma, and the chief commander Peng An were discussing the issue of food and fodder.

"Xiang Yan occupied the mountain road, and Huyang could not transport grain here. What about Biyang?" Sikong Ma twisted his beard and wanted Biyang to transport grain in the north.

"This..." Meng Wu knew that this strategy was impossible, but he still looked at Peng An, the commander of Zhisu.

"Report to the Guards: Two hundred and thirty miles from Biyang to Chengyang, one hundred and fifty miles of it is a mountain road. After the repair, it is just Tudao. It is very difficult to maintain the food and fodder of General Xinwu's troops. Our army has more than 100,000 grain and fodder a day, and it is a huge 15,000 stones of food and fodder per day. It cannot be transported by Tudao alone." Peng An explained, with a worried look on his face.

"Oh..." Sikongma said a long time. Tu Dao, he understood that there are three tracks, two tracks, and Tu monorails. These are the types and differences of roads. Tu Dao is a monorail, about eight feet wide, and you need to get a car when you meet a car. The plain is still good, and the light car can only be used to get a car on the side of the road, but there is no way to get a car on the mountain road, so you can only wait in a wide place. When the car on the opposite side comes, the car on the side can drive over.

"General Meng, what do you think?" Sikongma still kicked the problem back to Meng Wu. He was the guardian, and only supervised whether the main general was responsible for fighting. There was no obligation to solve practical difficulties.

"I thought I could only trap Chengyang and not attack the city for the time being. In addition to returning to the army and recapturing Fuyishan Road, the rest of the troops should join forces with General Xin Wu to attack Yiyi." Meng Wu took the map in front of him. The place he said was a hundred miles northeast of Chengyang, where the Qin and Chu coalition forces broke through the Wu army. "In this way, our army could eat Yiyi before the food road was opened. Moreover, this town was closer to Wei, and it was easy to obtain food for the Wei area to transport it, which could temporarily avoid the worries of food and grass, and defeat the gathering of Jing people.

The Jing people gathered in Cai on the north bank of Ru River, and on the south bank of Xi on the north bank of Huai River. The two places were only more than a hundred miles away from Yiyi. Our army defeated them and would be the hope of the defenders of Chengyang. At that time, the city could be defeated. Or…” Meng Wu smiled and said after laughing: “The King of Qin came to report that the King of Jing personally led the king's soldiers out of Yingdu to rescue Chengyang. If he could capture him, he would win this battle."

"The King of Jing personally led the prince's soldiers..." Sikong Ma was shocked and then asked: "General is going to attack Xi County?"

"May attack Xi County, and after reaching Yiyi, you should wait for an opportunity to move." Meng Wu was not sure.

"Good!" Although the captive prince of Chu, the Chu State, would ascend the throne immediately, Sikong Ma still agreed to Meng Wu's strategy.

"Since the guards have no objection, the general will be promoted to the tent to discuss matters." Meng Wu nodded to Sikong Ma and began to make specific arrangements. The next day, most of the Qin army moved north, leaving only 20,000 people to besiege Chengyang. In addition to the ten thousand people returning to the rescue and restoration of the country, more than 70,000 people met with Xinsheng's troops on the north side of Chengyang in Xiaoyi.

The Qin army went north without siege, and the defenders immediately used Feixun to report to the rear. The Grand Sima Nao, who received the report, did not understand the intention of the Qin army for a while. When he received the news that the Qin army advanced east on the fourth day, he realized that the Qin army was going to capture Yiyi.

*

"Why did the Qin army capture Yiyi?" Xiong Jing, who received the front line military newspaper, looked at the map and asked others. Of course, the others were not the prefect Lu Yangjun, but several clerks in the battle situation.

"Report to your Highness, when the ancestor Zhao King, the Qin people defeated the brother of the King of Wu in Yiyi with our army. This place was a plain and suitable for chariot battles. The Qin people attacked my shortcomings with their own strengths." After the attempted reform of the Grand Sima Mansion, the advisers of the Grand Sima Mansion who were idle and almost rotten were in a second spring. They always rushed to the forefront when answering questions, and were sneering.

"It's wrong. The Qin people came here to break the traffic in the city and then break the city before I was ready to break the city." Another clerk made a comment. This man ignored the news that more than 70,000 people from the Qin army went north and talked nonsense with his eyes open.

"Mr. Li, the Qin army is good at fighting chariots?" Another clerk wanted to speak, and Xiong Jing temporarily stopped him - Cai Bao and others had never fought with the Qin army. The King of Chu was concerned about King Zhao's attitude and was worried about his son's safety, so he was forbidden from leaving the palace to visit Lian Po. Therefore, Xiong Jing knew very little about the Qin army in the palace, and until he came to the Grand Sima Mansion, where there were many elderly people, and he often heard some real things in his words.

"That's right." Mr. Li felt quite proud when asked by Xiong Jing. He cleared his throat and said, "Among the nations, the Qin people have the most chariots, and the Zhao people have the most chariots. Among the Qin people's army, the military chariots are not the same as the soldiers, and they often form an army alone. In the Battle of Changping, after 25,000 Qin people's strange soldiers were cut off from the Zhao army, there were Qin people's chariots. Your Highness, I think that the Qin people's chariots were very fast. If you count the time of the news, I am afraid that the troops were already under the city of Linyi at this time."

"The Qin army was so fast that it was under Linyiyi City?" Xiong Jing was startled. What he didn't know was that the news that the Qin army advanced eastward had not yet reached the hands of the Grand Sima Naojiu, Yiyi had been taken down by the Qin army. Meng Wu used not chariot soldiers, but cavalry.

"That's right." His Royal Highness the Crown Prince was not completely speaking, but fortunately his words were clear.

"What did the Qin army mean?" Xiong Jing looked at Yiyi on the map, and was puzzled.

"Your Highness, the Qin people took Yiyi to prevent our north and south armies from joining together." Without answering, the other clerks of the battle said. "Our army was in Cai County for one time, and in Xi County for the second time, and Yiyi was only four sheds from Cai. If the Qin people guarded the Ru River, it would be difficult for our army to cross the river. If the Xi County was only three sheds, Xi County was north of the Huai River, and the Qin people would be raided when they went south."

"How should our army do?" No one speculated why the Qin army abandoned Chengyang and advanced eastward without attacking, which only explained the benefits and disadvantages of the Qin army advancing eastward. Xiong Jing naturally could not have imagined that Xiang Yan's more than 10,000 people forced the Qin army to give up the attack on the city and advance eastward to eat, and was only asking how to deal with it.

"Our army..." All the clerks pondered, and Mr. Li said, "Report to your Highness: The Qin people are coming fiercely. Our army should avoid their attacks for the time being and take the city to be decisive. Only when the army gathers together can we advance to fight."

"What Section Chief Li said is the best strategy." A group of clerks agreed, and the word "Section Chief" was extremely awkward.

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

"Your Highness, the strength of Qin is no longer something that a country can do. What we hold is that Zhao and Wei and other countries send troops to help. Even if Wei does not send troops, Zhao will send troops to rescue me. In this way, Qin is an enemy on both sides and will definitely withdraw from our country and return in vain."
