Handan City is the most unique among the capitals in the world. Its capital (small city) is outside Guocheng (big city). This arrangement made the Zhao people take a lot of advantage. For example, if the capital is inside Guocheng, the Qin army would surround Guocheng. Now the capital is outside Guocheng. The two cities are more than fifty steps apart and the corners of the city are close. To surround Handan, a longer front and more troops are needed.

In addition, the troops cannot be used between the capital and Guocheng, that is, the northwest and southeast corners. Once the troops are used, the defenders of the capital and Guocheng will attack at the same time, and the Qin army will be attacked from the front and side. This tactic was tried and tested in the last Battle of Handan. Now the Qin army is only forging defenses in these two directions, and the attack is mostly restraining.

This is the city guarding. Now hundreds of thousands of people are going to break out from the capital and Guocheng. This kind of capital and Guocheng are separated from each other is not suitable for formation of a calm formation. Even though Zuo Kai revealed that the Chu army would have five divisions and four divisions of Zhuyue (dissatisfied) assisted in breaking out, the military discussions in Sima's mansion still did not reach an agreement.

The capital city is more than fifty steps apart. In fact, the water flows through the capital city and the city of Guo. Whether to go out of the capital city to cross the water, travel north to Zhangshui, or go out of the capital city to cross the water, travel south to Zhangshui, this is not only a tactical issue, but also a political issue.

There is also the formation. The circular formation is the most stable formation. A circular formation with more than 400,000 people should be 800 people in diameter (S=πR2), so there can be 500,000 people in the circular formation; and the circumference of the diameter of the 800 people (C=πd) is 2,513 people.

If the diameter is reduced to 700 people, the circumference is 2,199 people. Each circle is reduced by six people than the outer circle (because the diameter of each circle is reduced by two times the pi, so the length of each circle is reduced by two times the pi, which is actually reduced by six people). One hundred thousand people are arranged in an array, which can form a military formation with a depth of forty-two rows.

However, the center of such a tight circular array is too narrow, which does not conform to the majesty of the king and noble people. At the same time, there is not enough space to place the royal palace's supplies, treasures, the gods of the former kings, etc. The royal court must have at least one hundred to two hundred steps to separate the royal court from the common people outside. In this way, the diameter will become one thousand people, and the outermost circle needs to stand 3,114 soldiers and 100,000 people in a formation, with a depth of only thirty-two rows.

The strategists did not know whether the depth of the thirty-two lines would be defeated by the Qin army. But what they could be sure of was that once the array of thirty-two people was penetrated, the Qin army would rush into the formation and kill. Therefore, all men, including temple people, craftsmen, must be armed to increase the depth of the array; women, as long as they could lift more than ten spears and halberds weighing more than ten, must be armed, also in order to increase the depth of the array.

However, this still cannot guarantee the safety of the king, queen mother and king court. The trenched catapults in the city are too heavy and cannot be moved, so they cannot be carried, but the Qin army can arrange catapults on the retreat route. The circular array is dense, and once the circular array is hit by the huge stone thrown by the catapult, and then attacked by cavalry, dozens of rows of deep lines will not be maintained...

How to eliminate the threat of catapults? How to assemble a giant circular array with a diameter of one thousand people? How to move to the west bank of the Zhang River more than 30 or 40 miles away after assembly? Should only one circular array be arranged, or should several elite Zhao troops be set up outside the circular array at the cost of reducing depth to defeat the Qin army's elite Zhao troops?

Lingswept all summoned the ministers to ask for advice, and the debates in the Guowei Mansion were all day and night. The formation, diameter of the circular formation, assembly location, assembly order, marching route, and marching schedule... were all the key points of debate among the generals and advisers. The general Sima, who was in charge of the military discussion, was unable to argue with Zhao Cong, Han Su and others. He knew very well that any mistake caused the collapse of the military formation would be a catastrophe for Zhao State.

Li Mu's confidant Hu Ying was not as cautious as him. When Zhao Cong proposed another plan, the angry Hu Ying quarreled with Zhao Cong, Han Su and others.

There were originally 50,000 kings and soldiers in Handan City, including 30,000 soldiers in black. When Yan Ju replaced Li Mu as a general, he led 20,000 elite soldiers to the north. After the 20,000 soldiers formation collapsed, only thousands of people fled back to Handan.

After the Zhao army on the Southern Great Wall withdrew, Wang Ting immediately selected 20,000 people from the Zhao army on the southern front as king's soldiers, and asked Sima Shang to return the axe and military talismans and retreat to the Guowei Mansion. In fact, it was to deprive Sima Shang of command of the army on the southern front by a blatant method. Now, the defeated general Zhao Cong cannot command the command of the defeated army. He can only re-grant Sima Shang's axe and military talismans. However, after several months of fierce battle, the Zhao army on the southern front was only more than 70,000 soldiers left, of which 20,000 were included in the king's soldiers, leaving only 50,000.

Zhao Cong means today: 50,000 kings and soldiers are responsible for protecting the safety of the king and the queen mother, so they are not arranged outside. However, the architectural structure separated from the capital and the Guocheng City is different. The Wangzhang Army will be placed within the Zhao army formation on the southern front. This means that the Zhao army on the southern front, on the outermost side, needs to protect the common people, the common people protect the king and the queen mother.

The diameter of the circular formation is still a thousand people, and the Zhao army 50,000 can only list thin military formations with a depth of fifteen elements. The Chu army abandoned the flower team and adopted a pure team, which had a great impact on the Qin army, making its military formation thicker and thicker, otherwise it would not be able to resist the endless battle of the Chu army's spear. The Qin army's military changes affected the Zhao State. In the past, the depths of three to forty lines were considered sufficient, but now the depths of five to sixty lines were also considered thin. Even if there was no spear formation in the fifteen elements, they would be defeated at once when facing the Qin army's sharp soldiers.

"If Zhao Cong is not dead, Zhao's army will still be defeated!" Zhao Cong came to inform, not to argue, just now it was Hu Ying who kept placing him on the argument.

"The Empress Dowager favors Guo Kai, but Guo Kai only believes in Zhao Cong, so that's all." Sima Shang said.

Compared with a year ago, Sima Shang has become much older. Especially when Yan Ju replaced the general, the news of Li Mu's death came, and he was ill at that time. Later, things unexpectedly happened. The guest actually assassinated the King of Qin in Xianyang. Countless people died in Zhangtai Palace and insufficient blood accumulation. This is not a Qin assassin, this is the Zhao assassin! Li Mu's head was just a talisman of the Qin people. The assassin suddenly attacked during the visit and almost killed the King of Qin on the spot.

Sima Shang was stimulated by this and commanded the Zhao army on the southern front with a sick body to retreat to Handan. With the strong heart of the Zhao people, he didn't care about Wang Ting's neglect. He inherited Lian Po and Li Mu's unfinished will. Hu Ying didn't know his psychology, and saw that he was indifferent, and said even more angrily: "It's better to have a time of Guocheng and a time of capital, and do his own things."

"No!" Sima Shang opposed. "The military formation is not a city wall, and one wave is not enough. How can it be divided into two waves?"

"What if? There are no soldiers fighting in the city, and the craftsmen are in the royal city again." Hu Ying was also angry just now, and it was obviously impossible for two formations.

"There is another person." Sima Shang said, and he thought of someone.
