When Wang Jian spoke loudly, the guard Zhao Hai looked at the father and son standing together and whispering. Wang Jian was recommended by Xiong Qi, the Changping Jun, and Zhao Hai was staring at his every move. Fortunately, the Qin army was not the guardian's responsibility system, but the general's responsibility system. Although Zhao Hai strongly opposed the retreat at the beginning of this year, he even broke the military power and finally compromised.

Wang Jian did not see Zhao Hai's gaze. After he finished speaking, he looked at the strategists who were still arguing fiercely. Four hundred thousand people went for nearly a thousand miles to fight, and it was definitely not a matter of time to determine how to support the logistics. He yawned and walked towards the tent behind the shogunate. After breakfast the next day, his confidant Liu Chi and others came to report with red eyes.

"If there is no horse-holding, this..." Liu Chi glanced at Wang Ao beside him. Wang Ao also had red eyes. He didn't say anything, and let Liu Chi speak with a stern face. "Isn't this battle..."

Before he could hear the word "No", Wang Jian coughed and asked, "For 400,000 people, the grain needs to be grained, dry firewood needs, and straw vegetation needs?"

"In winter, each person needs three stones of millet per month. For transportation, he can pound it first..." Liu Chi was intimate and replied that the millet eaten by the soldiers was in accordance with the military law. The military law states that every month, but suddenly it was converted into daily, and he couldn't calculate it for a while.

Liu Chi stuttered. The calculation behind him had already been calculated, and quickly wrote it on Mu Shu and handed it to him. Liu Chi glanced at Mu Shu and said, "The soldiers ate more than three and a half pounds of rice sauce every day."

"Are there more than three and a half pounds a day?" Wang Jian half-squinted his eyes and repeated, "So the whole army..."

"Such as the whole army..." Another piece of wood was handed over, and Liu Chi replied again: "400,000 people need more than 1,420,000 kilograms of rice sauce per day." After answering, he looked at the next piece of wood, and said again: "A four-wheeled cart can carry 4,000 kilograms, which requires 360 four-wheeled carts. In winter, it does not take the official road, so each cart needs four horses or four servants and cows, so it requires 1,440 horses and cows."

Liu Chi explained the questions clearly without waiting for Wang Jian to ask. Wang Jian nodded and asked again: "What's the dry firewood?"

"Each soldier needs six kilograms of dry firewood every day..." Liu Chi still looked at Mu Lu and answered.

"Six jin?!" Wang Jian opened his eyes widened when he heard this. Before the retreat, he had never paid attention to the dry firewood in the army. The dry firewood was all made along the way, which was also one of the regular jobs of auxiliary personnel. When going deep into the enemy country, the most convenient way to harvest firewood was to tear down houses. Yue's army "don't tear down houses" came from this. The daily consumption of dry firewood is more than corn. The hundreds of thousands of troops marched in winter, the more dry firewood is needed.

"Report to the General: Yes, it's very cold in winter, so there must be three kilograms of dry firewood." Just now, the wood slut calculated by Liu Chi Nianfa, and now the grain official came out to explain. "Even if there are three kilograms of dry firewood, it's a worry, if there is another kilogram of charcoal..."

"Three pounds are too much, how can I add another pound of charcoal?" Wang Jian shook his head, and he turned to ask, "The Jing people chased me, as if there was hot food, but there was no fire in Jing people. Why is this?"

When they chased each other, the coalition and the Qin army were only twenty miles away, twenty miles within Lu Lijing's vision. Compared with the cold Qin soldiers, Wang Jian had seen the Chu soldiers holding hot rice soup many times, and he still didn't know the reason until today.

"This is why the Jing people used mirage ashes." Wang Ao was very clear about this. "The Jing people placed the rice sauce meat soup in a small iron box, and the small iron box was placed in a large iron box. The large iron box was placed in another mirage ashes, and the food was filled with water, and the small box was boiling hot for a moment..."

"That's true?" Not to mention Wang Jian, even Liu Chi and other advisers were surprised when they heard this.

Mirage is not a magical thing. In "The Literature of Zhou: Qiu Guan Si Kou", it says: "The Red Fa Palm removes walls and houses, attacks them with mirage ashes, sprinkles poisons with ashes, and removes raccoons in all slits." In addition to deworming, Mirage ashes are also added when dumping silk.

But it was the first time to use it to heat rice soup. The ancients knew about the phenomenon of mirage ash and water producing heat. Tao Hongjing of the Han Dynasty once recorded in the "Shennong Bencao Jing": "Now, stones are produced in the mountains, blue and white, and they are burned into a stove and fertilized them with water. They will be heated and steamed and relieved. The nature is so strong that people drink it by drinking it with wine, and they will have abdominal pain and diarrhea."

"The soldiers of the Qi army once ate the Jing people's rice soup, so they know it." Wang Ao's news came from the Guowei Mansion, and the news came from the Qi State. The Qi people, who had not eaten meat several times a year, are still obsessed with the Chu army's large iron box. Many people retained the iron box as food utensils, and they were frowning whenever they talked about it.

"Our army can do this too!" Wang Ben left his saliva as he listened. He could eat hot food without ignition in the cold winter. It was a happy thing to think about it.

"Our army..." Wang Ao blinked slightly and said, "The king is quite concerned about this matter, and he expects it will be possible next year."

"Next year? Why not this year?" Wang Ben wanted to hold Wang Ao in a hurry. "The rice sauce is raw and cold in winter, and it cannot be cooked without firewood. Only by holding it in your mouth can you swallow it. Do you know, how many soldiers are there..."

Many soldiers died in the rapid retreat, and many of the Wang guards died. They were not killed in battle, but frozen to death.

"Irregular!" The son was excited, and Wang Jian immediately scolded him. When his son bowed his head, he said: "This matter will be reported to the king, and the king is very concerned. However, this year's attack on Qi is in winter, so I don't know why the food of mirage will be waiting for next year?"

The soldiers were frozen to death in batches and froze to death, so even if Wang Jian knew that dry firewood was more than rice sauce, he would not dare to cut it. If the real cut was spread, the general led the soldiers would inevitably resent him. Just because he did not want the general to lead the soldiers to resent, Wang Jian asked about the hot food of Mian Hui. He had seen the iron box on the hands of the Chu soldiers, which was not big, so we can see that there were not many Mian Hui inside.

"This is a difficult problem." Wang Ao regretted answering this question because it was still the secret of the Guowei Mansion.

"What's the difficulty?" Wang Ben raised his head again and asked regardless of my stare.

"The mirage is burned with mirage shells." Wang Ao said. "Although our army has destroyed Zhao, there is no good harbor along the coast of Zhao State, so I cannot get mirage shells. If I don't have mirage shells, there will be no mirage shells. If I don't have mirage shells, there will be no mirage shells. Can rice soup be filled with mirage water and heat it up, what if there is no mirage shell?"

I know that it may not be possible. Although the Qijia culture in the upper reaches of the Yellow River (now Qijiaping, Guanghe, Gansu) had an archaeological discovery of limestone burning to obtain limestone a thousand years ago, it was the upper reaches of the Yellow River. The Central Plains region did not start to calcinate limestone until the Han Dynasty, and the pre-Qin period was used to calcinate shells, mainly in Qi State. Even without the threat of warships, it was impossible for Qin State to want a large amount of mirage in a short period of time.

"So that's it." Wang Jian sighed inwardly. He looked at Liu Chi in disappointment and asked, "How many trucks of firewood are dry?"

"Dry firewood..." Liu Chi looked at the wooden mat in his hand, found the last number, and said: "Miracle ash..., no, no! Dry firewood, dry firewood costs 600 trucks a day."

"Six hundred cars?" Wang Jian pondered the number, "Horse and cow need two thousand four hundred?"

"Report to the general, that's right." Liu Chi nodded repeatedly. He was thinking about Mirage in his mind just now, but he was wrong.

"How many cars are there to carry?" Wang Jian continued to ask.

"There are 45,000 horses in the army, and 25,000 servants and oxen. Horses eat 32 pounds a day and oxen eat 80 pounds a day. Therefore,..., horse materials require 360 ​​carts a day, and oxen carts a day. "Liu Chi answered according to the numbers on the wooden mat. "This requires 3,440 cattle and horses."

"How many of them are?" Wang Jian raised his head and shouted. This time the number of people was smaller than the last time, but because he had to bring his own dry firewood, the logistics supplies needed were more than the last time.

"A total of 1,820 cars," Liu Chi did not look at the wooden squat this time, and thoughtfully calculated a number. One car is one ton, which is 1,820 tons. "It takes 7,280 horses and cattle."

"It takes 72,000 horses in ten days?" Wang Jian smiled bitterly. He only had more than 70,000 horses to pick up, and these horses only supported the ten-day journey. These ten days also included returning, which means that more than 70,000 horses to pick up can only allow 400,000 people to move forward for five days, and the sixth day could not support it because it was outside the supply limit.

On the five days, even if the carriage travels ninety miles a day (normally sixty miles), it is only four hundred and fifty miles away, and Linzi is still dozens of miles away. What he did not notice was that the five days did not include the consumption of the horse itself. If it was four horses and two masters, even if it was calculated based on the reduced amount of 32 kilograms per horse per day (eight kilograms), the daily loss rate was 3.4%, and in ten days it was 34%.

This means that one-third of the materials are consumed during the transportation process, and only two-thirds of the materials can be transported to the destination. Conversely, if you want to receive 1,820 tons of materials every day, the starting point must send out 2,757 tons, that is, 2,757 carriages. Only in this way can you receive 1,820 tons of materials every day.

Two thousand,757 carriages require 11,028 horses to pick up horses, and ten days to pick up horses, and one-tenth of the horses to pick up horses, about 120,000 horses to pick up horses. There must be 120,000 horses to pick up horses to support the Qin army to capture Linzi. There are more than 70,000 horses in the army, and the National Wei Mansion may be able to transfer another 40,000 or 50,000 horses. It is equivalent to relying solely on horses. If the Qin army did not seize a large number of horses, it would have to stop in Linzi.

In the past, not to mention 120,000 horses, even if it doubled, 240,000 horses, 360,000 horses would not be a problem. The problem is that there are too many carriages. If the road is not wide enough, the carriages will fill the entire road and cause the entire logistics to be paralyzed. The Qin Dynasty's persistence in roads is something that other countries cannot understand, just as they do not understand general mobilization and total war.

"What about the servants and cows?" Tens of 120,000 horses were not enough, so Wang Jian could only ask about the cows.

"The ox can only travel 60 miles a day, and it needs to eat 80 kilograms a day." When he mentioned the ox, Liu Chi shook his head. The ox walked slowly and ate a lot. Although the ox only had to eat hay and not eat straw, it was not as delicate as a horse, but long-distance transport of oxes was at a complete disadvantage.
