Four hundred Chu jin of iron bullets were placed in the middle of the shogunate tent, surrounded by Qin generals, including the prime minister of Wei, Ziji. After he was imprisoned, he was waiting for death. Who would have thought that one day the gods appeared, the King of Wei personally went to the prison of court and knelt down and asked him to come out and serve as prime minister. Now, he is leading 200,000 Wei troops to attack Chu with the Qin army.

‘You are riding a car, I wear a li, and when we meet each other, we get off the car and bow…’ This is a completely chaotic era. One night of wealth and wealth, and another day of poverty and humbleness have become a daily routine.

"Is this really an iron bullet?" Zi Ji Fengcai was still, her face was even rosy than a few months ago. The iron bullet was about half a foot in diameter. This one failed to hit the van and broke into two halves after it fell to the ground. Its appearance was round, and the cracked surface was bumpy. You can see the iron particles inside.

"It's the iron bullet." Yan Wuyi came at the right time. As soon as he came, including Xin Wu, he bowed to him. "Only the iron bullet can destroy my three-foot giant wood rushing car. I have ordered the four-foot log to rebuild the city. As long as the wood is safe, the rushing car can be completed in ten days."

The safest way to build a corridor to reach the city is. The Qin and Wei coalition forces must take down Chencheng this time and build a bridgehead to attack Chu next time. I didn’t want Xin Wu to interfere, and said, “This bullet weighs three or four hundred kilograms, all of which are fine iron. If one kilogram is worth ten qian, that is three or four thousand qian. Today, the Jing people can’t give away five or six hundred qians, which may be worth two or three hundred gold…”

The Chu people fired iron bombs, which were very expensive things. They threw out two or three hundred golds a day, so they would definitely not be able to hold on. Even if they didn’t care about money, an iron bomb weighed four hundred kilograms, and five or six hundred kilograms were more than one hundred thousand kilograms. No matter how much it was consumed, it could not be able to hold on.

"The General is Miao." Yan Wuyi said frankly without caring about Xin Wu's face. "The Jing people have the art of great iron and evil iron. King Jing once told people that the Jing Kingdom's huge iron is not worth a penny, so the price of evil iron is naturally cheaper. We think that five or six hundred iron bullets are worth 200 to 300 gold, but in the eyes of the Jing people, it may only be worth 20 to 30 gold..."

In the Qin army's tent, four hundred Chujin's iron blasts cracked in half, but the iron bullets next to the catapult in the city were round. Each iron bullet had a word "C" on it, indicating that it was a type of city-breaking bomb. In the group of catapults, the soldiers were running vigorously in the turntable, and the "knock" sound continued. Every three minutes, more than ten iron bullets were thrown out of the city, smashing the rushing cart covering the long wall even worse.

"Stop issuing the cannon." The lookout hand raised the flag on the city wall, and the army under the city immediately called for a stop. After a few "kicks", the catapult finally calmed down. A group of treading soldiers lying on the ground, panting and gasping.

"Count the bullets." The commander of the armored soldiers is a weak Lu artificial technician, Gongshuji. It is almost impossible to make an illiterate officer understand ballistics, but it is easy to make a technician understand these. As for whether he is brave or not, he should not go to the battlefield anyway, and they always fight in safe places.

"The general has an order, count the number of cannons immediately." Gongshuji's voice was too small, and his orders must be conveyed by the tall deputy general beside him to all the cannons before he could hear it. When he shouted loudly, counting sounds came from each cannon.

"Report to the general, there are 320 iron bullets, 675 stone bullets, and 51 lead bullets." The military officers gathered the numbers and told him loudly. Gongshuji frowned when he heard it. Twenty catapults, not counting lead bullets, and on average, only less than fifty catapults were available. "Report to Yingdu, our department has a serious lack of bullets, and only enough for a battle."

"Ye." The military officer agreed loudly and ran to send a message. He had been urging the shells several times in half a month, but he had never added them.

"Reported, Chen Ying urged the shells again. He said that the shells were less than a thousand, only enough for one battle. He asked for five thousand iron bombs." After the telegrams sent from various places were classified, a small half were sent to the Transportation Department, which was the busiest department except the Confidant Department. He was so busy that the director E Zhuo personally calculated the marking on the big blackboard.

"Five thousand rounds?" The big blackboard occupied an entire wall. E Zhuo, who was covered in chalk gray, was standing on the wooden ladder. Hearing this, he turned around in surprise. Four hundred Chujin shells, five thousand rounds were five hundred tons.

"That's right." The little official nodded repeatedly, saying that he had read it wrong.

"Chen Ying adds 500 tons." There is a large table on the blackboard, with the top row at the table. The grid says Chen Ying, Xiangcheng, Xincai, Pingyu, Chengyang, Muling Pass..., all of these places are battlefields; the grid is in the left column, and the grid contains major counties and towns in the country, including Yingdu, Chenying, Xiangcheng, and Chenying. Xiangcheng is also marked as this because it wants to transport people out of the people.

E Zhuo said that Chen Ying added 500 tons, not adding 500 tons to the top of the table, but adding 500 tons to the grid corresponding to Chen Ying at the bottom of the table. At the top of this grid, there are a total number written in Arabic numerals, and the unit is to tons; under the total number, there are many numbers, and the front end of the number reads: corn, straw pole, wood, quilt, soldier armor..., 500 tons of shells were added at the bottom of the grid, and the total number on the top was also wiped off, adding 500 tons, which represents demand.

There is a column on the rightmost side of the table, just like the bottom line of the table, and there are some numbers written in each grid of the corresponding city. The top is a large number, and the bottom is a decimal number of various materials, and the unit is also tons, which represents supply.

The upper, lower, left, right, left and upper form indicates the city, and the right and lower form represent supply and demand. The table in the middle is not empty, and there are also some numbers written on the upper left of the grid. This represents mileage. That is: how many miles does the material from City A have to transport to the upward sub-land? For convenience, all land routes are converted into water routes.

"Redefine the initial plan with the minimum element method." E Zhuo beat his forehead and ordered. When he was determined the initial plan just now, he was so tired that he fainted, but there was no shell, so he had to recalculate it to give Chen Ying the shell.

Feeling from the chaos of military transportation last year, this year, the Grand Sima Mansion began to use the table transport operation method taught by Da Wang to guide the arms transportation. That is, the demand and supply quantity of the demand and supply quantity of the demand and supply, and at the same time determine the mileage (freight) between each place and each place, and then work on the table. This is the calculation method of using the list method to solve the transportation model in the linear planning problem, avoiding a large number of linear equations that no one can understand, and is considered one of the quick-acting linear planning solutions.

E Zhuo's brother is Ejun, the vassal of Ezhou. Ezhou is right by the Yangtze River and its boats are connected to the whole country. The Transportation Department can only let Ejun's people be responsible. First, Ezhou has been in business for a hundred years and has a lot of transportation experience. Second, the E family has many sailors, so it is difficult for others to be the director of the Transportation Department to mobilize Ezhou boats.

The solution to the list is very simple. As long as you can add, subtract, multiply and divide, you can even add, subtract, but the problem is that the actual problem is often more complicated than the standard model. For example, the standard model only supplies and sells a single goods, but in reality there are corn, straw poles, wood, quilts, weapons, arrows, coal... 10 or twenty kinds of goods; the supply and sales quantity of the standard model is always equal, and the actual sales quantity is never equal; because the standard model only has a single goods, there is no material level, but in reality, various materials have levels, and sometimes food and fodder are the most urgent, and sometimes weapons are the most urgent.

Another thing is that the optimal solution solved by the operations on the table is just a cargo transportation plan, which does not mean that there are so many ships that can transport the cargo to the destination. To be honest, in order to truly be scientific, the shortest path problem must be solved. This is not something that E Zhuo can do with four knives, and only Xiong Jing himself calculates and solves it.

"The five hundred tons of shells in Yingdu were transported into Chenying," a method standing on the wooden ladder replaced E Zhuo and began to find the initial transportation plan with the minimum element method. He wrote Chen Ying in the top line, and the intersection of Yingdu on the left side, and wrote 500 tons of shells in the intersection.

"The 500 tons of shells in Yingdu were transported into Chenying, and Yingdu minus 500 tons of shells." There is a method repeated in the right column of the large table. He placed the right column of Yingdu supply grid and subtracted the shells by 500 tons.

"The five hundred tons of shells in Yingdu are transported into Chenying, and Chenying is reduced by 500 tons of shells." The big table is at the bottom, and another method is repeated. The lowest line represents the demand. Since the five hundred tons of shells have been "transported into Chenying, this demand must be reduced.

"Chen Ying's shells are satisfied, mark the line." The last calculation supervises the entire calculation and confirms that everyone has done it correctly, so he ordered the line to be drawn. The column with Chen Ying written at the top is marked with a black line from top to bottom. The black represents the shells. The marking means that Chen Ying's shells are satisfied, and does not mean that Chen Ying's other materials are satisfied.

"Fifteen tons of millet are transported into Chenying." The law calculates the fifteen tons of millet in the intersection of Chenying and Yangling.

"Fifteen tons of millet in Yangling were transported into Chenying, and fifteen tons of millet were reduced." Yangling, the right-hand row, supplies Grey, and minus fifteen tons of millet, was zero.

"Fifteen tons of millet are transported into Chenying, and Chenying reduces fifteen tons of millet." The following Chenying demand grid is required, and the millet is reduced by fifteen tons.

"The corn is still insufficient." The last voice of the calculation was that Yangling was closest to Chen Ying. Yangling's millet was not satisfied with Chen Ying, so he could only draw the millet from a longer distance to Chen Ying. "Get Juyang millet."

"Twelve tons of Juyang millet are transported into Chenying," the table continues to work, and the other wall opposite is also working. Unlike the table wall, this wall is drawn with a tree map, similar to the map of Chu, but all roads are simplified, with only points representing cities and roads, with arrows drawn, and various numbers beside the lines.

In addition to being limited by supply, the transportation of materials is also limited by transportation tonnage. If the operation on the opposite table does not call out a number, some numbers will be added to the number chart. When the calculation recorder shouts, "Two hundred tons of coal in Quyang are transported into Chenying...", someone on the tree chart said coldly: "The tonnage of Chenying's route is insufficient."

"How much is left in the tonnage?" Fasuan turned around and asked. After most of the materials were transported, coal was not very important.

"Only seventy-nine tons remain." After checking the numbers on the tree map, he answered.

"Quyang seventy-nine tons of coal are transported into Chenying." The method of calculating wipes off the two hundred tons written in the grid and changes it to seventy-nine tons. Following his actions, the rest of the method also changes the numbers in the grid.

"Chen Ying's materials are 'full', mark the line." The last name of the law ordered the lines to be drawn, indicating that Chen Ying had no more material demand in this round.
