The strategists discussed the whole day yesterday and discussed everything they should discuss. The existing horses travel 90 miles a day, and can support Linzi, but they can't go further. There is another serious consequence of traveling 90 miles a day: the loss of horses will increase. In order to reduce the loss of horses, they also need to feed more essential materials, which increases logistical pressure.

Winter combat is a disaster, which requires more corn, more dry firewood, more straw vegetation, and more horses and cattle. If you do not fight in winter, you will face the front and back attacks of the coalition warships - the river flows eastward until the Gaotang only 90 degrees north of the Gaotang, and the Gaotang is about 150 miles north of Pingyin Fortress. Once the coalition forces go to the land from Gaotang, they can directly descend to the rear of the Qin army;

Laizhou Bay is about 150 miles north of Linzi. If the Qin army outstripped Linzi and continued to move eastward towards Weishui and Muling Pass, the Chu army would also lead the Qin army to land in Laizhou Bay. Because of the existence of Mount Tai, the Qin army could not choose other paths, and must first unplug Linzi before advancing eastward.

In addition, there is also a road in Lu that can penetrate directly into Linzi, which is the Wen River that starts from Mount Tai, flows to Lu, and the Zi River that starts from Mount Tai, flows to Linzi. In 684 BC, the Cao Gui debate, which is familiar to later generations, that is, the Battle of Changshao, took place on this road; in 500 BC, Confucius was used as the minister's courtesy, and the Luqi Jiagu League, which was brought back 30% of the Luqi Jiagu League on Wenshang, also took place on this road.

Fortunately, this is an ancient road built hundreds of years ago. Even if it is not damaged, it cannot support the logistics supply of more than 100,000 people. If the Qin army blocked the pass in Qi, compared with the previous two, this ancient road that can be directly inserted into Linzi is not very dangerous.

Only winter is safe, but in winter, the attack cannot be due to food to the enemy. It also requires carrying dry firewood by itself, which increases the logistics burden. Tens of 120,000 horses are not enough, so Wang Jian had to ask about the ox.

Wang Jian asked the Puniu, but Liu Chi had to answer honestly: "Puniu can carry 6,000 kilograms per truck, but if it is transported to Linzi by Puniu, it will take 10,000 kilograms a day, and Puniu only travels 60 miles a day, so it takes 16 days to travel..."

Liu Chi can no longer say this. Since the ox carts that arrive every day require 10,000 cars, the round trip is 160,000 cars. One cart of four oxes requires 640,000 oxes. Considering the huge appetite of oxes, this is astronomical.

"Ten thousand cars a day?" Wang Jian was also shocked by this number. The carriage only requires 1,820 cars, but the ox carriage requires 1,820 cars.

"Yes," Liu Chi said. "The servants eat a lot and travel only 60 miles a day, even if they carry 6,000 kilograms."

"Four servants and cows, carry six thousand pounds?" Wang Jian silently recited the number.

"Yes." This time Liu Chi did not calculate the wooden slut, and he repeatedly confirmed the transportation of the ox. "There are cattle heavier than the horse, and there are also those who are not as heavy as the horse. Although the cattle has a strong strength, its body is not strong and it is not much better than the horse."

The pre-Qin cattle are mostly cows in "Qin Qin". What kind of cows are cows in "Qin Qin"? This is a breed of cattle in the northwest region, or can be called Qin cattle, Qinchuan cattle. The weight of Qinchuan cattle is generally around 300 kilograms, and the weight determines the strength. The normal strength output rate of cows is about 5% higher than that of horses. However, the weight is similar, and 5% more is also very limited, but it is only fifteen kilograms more.

The pulling force of a 300 kilogram horse is about forty kilograms, and the pulling force of four horses is about fifty kilograms; the pulling force of a ox is about fifty kilograms, and the pulling force of four cows is about fifty kilograms, and the pulling force of four cows is about fifty kilograms, and the pulling force of four cows is already overweight with 1:6.25 = pulling force: the pulling weight ratio. The pulling force of four cows should actually pulling 1,375 kilograms, and pulling 1,500 kilograms is already overweight.

"Maybe, maybe..." After Liu Chi said that when Wang Jian was silent, a strategist wanted to speak but had some concerns.

"Yes!" Wang Jian immediately stared at him, hoping that he could have another idea.

"Reported to the great general, Zhen Ping, the villain traveled to Minshan when he was young, and heard that there were kui cattle in the local area. The ox weighed thousands of pounds and was as big as a cloud..." When Zhen Ping spoke, other strategists stretched their necks and looked at the curtain on the top of the shogunate. The ox was something that only existed in myths. Even if there were, it was in Minshan. Minshan was a land of Shu and was owned by the people of Chu.

The strategist was like this, and Wang Jian was also a little anxious as he listened, "Where are tens of thousands of cattle?"

"Report to the general, although there are no cattle, I, Qin, have Qin cattle weighing thousands of pounds. If the National Wei Mansion can choose Qin cattle weighing more than three thousand pounds for transportation, it may not be lost to cattle." Zhen Ping is a young man. He mentioned cattle last night and was ridiculed by everyone. Unexpectedly, what he mentioned is Qin cattle weighing more than three thousand pounds.

"This method is feasible?" Wang Jian stroked his chin and thought.

"The villain thinks it is feasible." Zhen Ping replied. "The villain looks at the iron cavalry of the Jing people, then look at the iron cavalry of the Great Qin people, and then look at the news about the Great Chu people. Only then can we know that the horse is not tall and can bear armor, but the weight can bear armor. In this way, the heavier the cavalry of the cavalry, the greater the force. If there is a Qin ox of more than three thousand kilograms, a cart can be carried by two oxes instead of four oxes, so the few oxes are."

"This..." Wang Ao also listened to Zhen Ping's words, "In this way, the National Weifu Mansion wants each county to select the heavy bull?"

"However, the heavy force is great. Even if you eat a lot, it will be less than four cows." Zhen Ping said this and took out a piece of wood from his arms and said, "This villain is planning, please check the general."

"Each car is eaten..." Wang Jian subconsciously took it, looking at the number above, what surprised him the most was the number at the end: "...it takes 5,500 cars per day?"

"Of course." Zhen Pingdao, Liu Chi and others were already staring at him. "There are more than 88,000 ox carts. Two ox carts per cart, and two hundred thousand heavy ox carts are enough. Even if you eat 120 kilograms of carts every day, you can save it than the former."

"A servant cow with a capacity of more than three thousand kilograms requires 200,000, which is difficult." Liu Chi was unhappy and Zhen Ping did not report to himself first and directly reported to Wang Jian. "So there is, how can we prove that two cows can save a capacity of six thousand kilograms?"

"A ox with a capacity of more than three thousand kilograms is twice as powerful as a horse. The four-wheeled carriage comes from Jing State. Jing State takes one horse to one thousand kilograms, so four horses to four thousand kilograms. However, Jing people rarely use servants to pull the cows, so it may not be a ox to pull one thousand five hundred kilograms, or a ox can take two or three thousand kilograms..."

The transportation of four-wheeled carriages was learned from the State of Chu. Why did the Chu people use four horses to pull four thousand pounds? The Qin State does not know the principle. Why did the Chu people use four oxes to pull six thousand pounds? The Qin State does not know the principle.

The friction coefficients of pulling the strength, pulling the weight, and the friction coefficients in various roads (wheels), only the Grand Sima Mansion Operations Department and the Armed Service Department know the principles and parameters. Although there are experiments, Xiong Jing has required this from the beginning - the internal regulations of Pla during the Civil War were clearly stipulated, and then it was posted because of the controversial history of Chinese field artillery. As for the pulling strength of the Niu, he basically also had a 15% weight pulling formula.

He knew how to do it, but he didn't know why he did it. This was the situation that the Qin army was facing at this time. Zhen Ping had figured out some principles, so he suggested using two heavy cows to pull them instead of four.

"Father, whether it is OK or not, you can try it." Wang Ben was fearless and had no rules and regulations in his mind. He was more inclined to accept Zhen Ping's suggestion. The result of this was that 200,000 cows and twelve horses could support the battle to destroy Qi.

"If this is the case, let's try it first in the next few days." Liu Chi and Zhen Ping were still arguing about how heavy the u Niu could pull, and Wang Jian said.

"General, transportation has been a matter of years, but it is only a few months away from attacking Qi. How can I try it?" Liu Chi disagreed with the test because it was too late. "The spies and scouts of our army all said that the Jing people used four oxes to pull 6,000 pounds. The Jing people would do this. How can they change it at will? If the ox is too heavy during the war and many servants are dead, what if it does?"

"This matter should be cautious." Wang Ao originally supported Zhen Ping, but when he heard Liu Chi's words, he felt that what he said was not unreasonable. "Maybe ask the National Weifu to select a cattle weighing more than 3,000 kilograms from each county, and then..."

"If this matter is known to the people of Jing, I may lose its secret." It is also said that it was several military strategists in the shogunate. They were not considering logistics, but attacks. The county and counties across the country selected a large-scale ministry and county, and this decree would inevitably be intercepted by the Knowledge Division. Once intercepted, the people of Jing knew that the Qin army was preparing for an offensive battle.

The words of the military strategists made the military station quiet. Wang Jian did not say anything about the experiment, nor did he ask the National Weifu to select the heavy bulls from the counties and counties across the country. Instead, he waved his hand to let the strategists retreat, leaving only Wang Ao, Liu Chi, Wang Ben and other three people.

The map of Qi State has been spread on several tables in front of Wang Jian. Some important cities on it have become dirty because of too many touches. The river flows north from Gaotang, and the Ji River flows out of Dongjun and goes eastward, cutting the entire Qi State into two halves.

The inability to use the Ji River was the first reason for the difficulty of the Qin army's logistics; the inability to invade Qi State when grain was harvested in September and October was the second reason for the difficulty of the Qin army's logistics. If there were no threat of the Chu army's warships, Qi State would have been wiped out by the Qin army long ago.

With his five fingers on the map of Qi, Wang Jian asked Wang Ao and Liu Chi, "Is it OK to attack Qi in September?"

Similar questions have been asked several times, and Liu Chi always answered no. This time he wanted to answer but did not answer. Instead, Wang Ao replied: "If you can't go down to Pingyin quickly, you must not."

"However, if I cut all the Qi in September, I can get corn, dry firewood, and straw robe!" I put away my five fingers on the map, and then waved them in the air. With the waving of my arms, Wang Jian's short beard was also floating.

Two hundred thousand cows and 120 thousand horses, this is just logistics. There are still 45,000 horses and 25,000 cows in the army. He did not look at it carefully, but the amount of straw chew needed for so many cattle and horses is a huge amount. Dongjun, Hanoi County, and Qinghe County. Can these counties provide so much straw chew? He felt that it could not.
