It seemed to be a life-and-death race, the Zhao people in the city rushed to make weapons and train formations day and night, while the Qin army outside the city carried trebuchets and crossbows with all their might, and dug trenches and built earthen walls in the north and south of Fushui. The tense situation is like the second battle of Changping, and then the city is surrounded by all the food in the country, and now only the most elite soldiers can be concentrated to prepare for a breakthrough, and only a breakthrough can survive.

September Xin Chou, another sleepless night passed, the sun was about to rise as usual, taking advantage of the last night, Wang Zhizhi rushed Zhao Cong to the Governor's Mansion again, he also did not sleep all night this time, his eyes were bloody.

"Formation!" Zhao Cong looked at the fox baby who came out of the room to greet him, his words were indignant, and he threw down a thick array map when he spoke.

"Where?" The formation diagram was written and provided by the National Commander's Office, and it contained the precise numbers and accurate angles required for the formation and the detailed number of ranks to guide the formation of each lieutenant and Zhao army. A circle is different from a square array, and a circle has an arc.

"The king's array is not more than four hundred people, which is insufficient." Zhao Cong stopped talking, and what he spoke was a soap-colored dress that came with him, which is a legal calculation.

"The king's array is less than 100,000 people, and the number is indeed more than 75,000, why is it insufficient?" The fox baby looked at Zhao Cong very strangely.

"More than 70,000 people plus chariots and horses, it is already 100,000, a circle formation instead of a phalanx, and the width of the formation is less than 400 people." Fasuan argued: "There is a way that is one and three days, and half a path is multiplied by a week, and four into one gets its product." Today, the width of the 400-step array is not more than 60,000, how can it be enough? ”

"You ......" In ancient times, the ancestors knew that the diameter is one and three, that is, the circumference of the circle is three times the diameter, for which several methods of calculating the area of the circle were deduced, and the method is now talking about one of them. It's okay to quarrel with others, but the noisy arithmetic fox baby really didn't dare to speak indiscriminately, he could only order: "Quickly go to the big room to find the law." ”

"Hmph." Yesterday, the fox baby scolded people without dirty words, and Zhao Cong, who was scolded for his bloody head, saw that he was now dignified, and rarely snorted twice.

"Good dogs don't bark." The fox baby didn't look at him, just looked at the air and said, Zhao Cong was angry again.

"Chief, what is the matter with the law?" Left and right and back, the law did not come out.

"What's the matter?!" The fox baby's eyes widened, he couldn't wait, so he threw off everyone and went into the big room to find out what was going on.

"After crossing the water, a few steps to the hills, a few steps away from the Qin people's tools to break the city......" The law calculations were busy, and the lookout posts on the high places in the city had been closely watching the movements of the Qin army, and the cavalry kept going out of the city to actually measure the distance everywhere. However, among all the voices, it was a child's voice that mediated in the center, and the fox baby rushed directly to him and said: "There are people from Wangcheng, and the width of the 400-person formation is not more than 60,000, which is not enough. ”

"How can the width of the 400-man formation be 60,000?" The boy with hanging hair in his teens, this is the general law of the National Governor's Mansion. "Two and a half of the diameter, two hundred times two hundred is forty thousand, and multiplied by three points one hundred and four hundred and fifty-nine is one hundred and twenty-five thousand six hundred and sixty-three."

Mu Wei looked at the fox baby a little stunned, he was a person from the school, and he was recommended by Crane Guanzi to enter the Guowei Mansion. Arithmetic is his forte, and it is mental arithmetic. The "Nature" textbook of the Chu State School is almost equal to the primary school textbook of later generations, and the solution of equations is not available in this era. The mental arithmetic is fast, and the solution is accurate, and the thirteen-year-old Mu Wei is already the chief legal calculation of the National Governor's Mansion.

"He must be wrong in the number. Forty percent instead of two percent. "Mu Yan didn't understand the contradiction between the Governor's Mansion and the royal court. He knows that other methods only know the ancient parameter of 'one week and three days', and if the other party calculates that it is really 60,000, then the only explanation is that the divisor is divided incorrectly. Radius by circumference, four into one; Half times the circumference, then it will be two into one instead of four into one.

"They are dog thieves!" The fox baby scolded viciously and ran out with kicks. After a while, the fox baby's violent scolding resounded throughout the Governor's Mansion. When the belly lord was scolding, the sky was gradually brightening, and when a Zhao pawn who was standing on the ridge of Handan's main bedroom in the north wind picked up Lu Lijing and looked to the east, 'Ah', Lu Lijing did not hold it firmly and fell on the roof.

Longtai is the highest rammed earth platform in Zhao Palace, so it is standing here, and it is nothing to break a Lu Lijing, so I am afraid of disturbing the king. However, Zhao Zuxin, who had fallen off the mirror, was still hanging, and his companion had already beaten the drum, and shouted to the bottom in a broken voice: "The Chu army is the best!" The Chu army is the best! The Chu army is the strongest. ”

The sky is getting brighter, and at the end of the white and frosty land are boats and masts that stretch for dozens of miles. It was a tributary of Zhangshui and the Yellow River, and more than 4,000 boats sprang up on the river overnight. These boats include fishing boats, boats, Qinghan, and boats, as well as old and new wings, as well as sea boats and Chaos-class gunboats with mastheads and sails.

The Yellow River is wide, plus more than three miles wide Zhangshui, fifteen miles wide water surface, the boat still occupies more than 30 miles of the river. The Qin soldiers fortified on the west bank of Zhangshui woke up and saw so many boats, only to feel that the sky was getting colder and colder; Zhao Zu, who was looking up from the roof of the four heavy houses, saw that the sails of the Zhangshui River were full of shadows overnight, and his heart was full of fire.

Princess Han sent Zhou Ji to save her Zhao Ren Xing, but some people said that it was the Chu people who lied to us. The Chu people only wanted the Zhao people to hold Handan, and they wanted to expand their territory in the west, and they didn't want to save the Zhao people at all. Besides, there are more than 400,000 Zhao people in the city, and there are only a few hundred boats outside the city, so there are so many boats in the world to save themselves? Even if there is a boat to save it, it is to save the nobles of the palace.

The people's hearts are panicked, the army and the people are integrated, and the people's hearts naturally affect the army's hearts. The moment before seeing the dozens of miles of boats, no one could guarantee that the boats could save more than 400,000 Zhao people, but now when they see the boats, they are filled with Zhangshui and big rivers, all the momentary worries disappear, and every Zhao person can board the boat and go south.

The sound of drums on the ridge of Longtai woke up Zhao Qian, who was sleeping soundly under the house, and then the spirit robe in the small bedroom, the temple people and maids in the palace. When the drum at the head of the royal city wall sounded, the entire royal city and the whole Handan were awakened.

"How geometric is the Chu people's boat?" The spirit robe who had arrived in a hurry asked as soon as he spoke.

Zhao Shu, who looked at the "Empress Dowager ......", was not surprised by Ling's beautiful appearance, he was in a burst of inexplicable excitement. When Lingyuan asked, his two hands unconsciously pointed behind him and to the east, "Zhouji, Zhouji...... Countless also! ”

"Myriad?" The spirit robe was full of surprise, and her plump buttocks left the seat, and then sat back down, full of elasticity. "Good, great good."

"Tai, Queen Mother...... "Zhangshui, the tributaries of the Yellow River can indeed be described in countless ways, but this has something more exciting, Zhao Shu continued: "The villain found a phoenix flag in the boat. ”

"Fengqi?!" Lingluo looked at Guo Kai with an expression of disbelief.

"What kind of phoenix flag?" Guo Kai asked, as long as you often watch the news of Da Chu, you know that wherever the king of Chu appears, there must be a phoenix flag.

"Flag white, phoenix color,...... There are three more..."Zhao recalled the scene he had just seen. The phoenix flag is not one, but dozens of boats are all planted with phoenix flags, but there is one largest.

"The king of Chu is the best." Guo Kai, who has always been gloomy and unsmiling, smiled on his face.

"Father, King Jing is the best!" Handan had to stand on the highest place to see Xiongjing's royal flag, and the Qin army, which was blocking between Zhangshui and Handan, was not so troublesome. Since last night, the military reports of the scouts have been continuously transmitted to the shogunate, but Wang Jian has already fallen asleep and will not listen to the reports. When he came in the morning, Wang Ben broke in to report. The shirtless Wang Jian was bathing in a wooden barrel, and a servant girl was pressed under him.

"Get out!" was quarreled with by his son, and Wang Jian immediately waved his hand to let everyone withdraw, including the maid under him.

"King Jing has arrived, and Jing Renzhou has arrived?" Wang Jian in the wooden barrel continued to scoop water with a gourd and pour it on his body.

"Yes." Wang Ben nodded. "The boat stretches for dozens of miles, and the eyes are endless."

"King Jing is to the king, the people of Jing and Zhao should be united inside and outside, this battle is ......" Wang Jian was not in a good mood. The King of Qin had already ordered him to prevent the Zhao people from breaking through, and he had to calculate the loss of troops consumed by the blockade, and if he lost, the newly acquired Lord of the Great Princess, who would not be able to keep it.

"Uh-huh——!" Thinking that there was a chance that he would lose in this battle, Wang Jian made a heavy slap. He didn't say anything, but the gourd scoop in his hand kept slamming the water until it turned into pieces. The sorrow of the Qin army generals is that they cannot be made marquis, once a general is promoted to the rank of grand commander, the national lieutenant's mansion will let him complete the most difficult task. Don't go, cut the knight; went, lost money, or cut the knight.

If you want to be a marquis, you can only do it with miraculous feats. The Battle of Changping was a miraculous feat, with 500,000 or 600,000 beheadings at a time; The battle of Yanying was also a miraculous feat, not only beheading hundreds of thousands, but also occupying hundreds of miles of cities in the Chu State. Even so, you still have to be cautious at ordinary times, otherwise you will follow in the footsteps of Wu Anjun.

"It is a great sin to let Zhao people go; If you don't indulge in Zhao people and go dead, you will be killed, what should you do? "There is nothing that cannot be talked about between father and son, Wang Jian retreated from the left and right servants to discuss things with his son.

"There is news in the palace, is it true that the king and the state captain are talking about it?" Wang Jian didn't answer and asked about another thing.

"No news." Wang Ben shook his head, "However, according to common sense, my father's lord is reduced to Daliangzaoke." This has been under the Jing people to descend to Jinghua. ”

"Daliangzao?" Da Liangzao is the sixteenth rank of the lord, Wang Jian was silent for a while, and finally said: "No, the prime minister has fallen, and there is no one in the Nai Weng Dynasty, so he can only go to the left chief." If it is too high, the king will condemn him. ”

"Zuo Shuchang?!" Wang Ben was dumbfounded, he knew that this battle required a strong man to break his wrist, but he didn't expect that he would reach the tenth rank of the knight as soon as he broke it.

"Alas!" There are people in the DPRK who are good officials, and it is common for them to tend to be inflammatory. Wang Jian relied on Xiong Qicai to stand out from many generals, but Xiong Qi was already in Xianyang last month because of his knowledge of Chu, and most of the officials in the Chu family were implicated.

"The only way to fight to the death is to fight to the death." Thinking of the car cracking, Wang Jian sighed helplessly and his eyes suddenly sharpened. Shrewd, he worries not only about his title, but also about his life. Only by fighting with one's life can this battle regain the trust of the king, otherwise......
