The counties contracted to the old man's clan were all in the west, and they naturally did not want to fight with the Qin State, and after suing the temple, these people gradually proposed to negotiate peace with the Qin State, but they never expected the Qin army to fight again. Last time 400,000 troops were sent, and this time 500,000 troops were sent.

According to Zhibisi's estimates, the 500,000 army is the scale of the army directly under King Qin near Xianyang after mobilizing the border army and Xianyang, which can be described as a national army. And they are no longer as focused on containment as before, and they are likely to bypass the fortified city and go deep into the hinterland of the Chu State.

Xiong Jing asked, although Cai Wen and Cheng Jie were dissatisfied in their hearts, they could only reply: "Since the Qin people have sent troops to attack me, there is nothing to talk about. ”

"What do you think?" Xiong Jing remained silent, he was always trying to find a way to pull his old man to the position of Qiu Qin, but it was useless for him to pull, and the best way was for the Qin army to attack Chu.

"I think I should strike first." Fight in the pheasant road. "200,000 Qin troops came from Nanyang County, and after arriving in Chengyang, tens of thousands of people were left outside the city, and the rest passed through Yiyi to Xixian and Xincai, and the army on this road occupied the land west of Rushui; Shang Cai's army went down the river and occupied the land east of Rushui and west of Yingshui. The military ministers of the chasm thought that they were not attacking Chen Ying, Chen Ying was in the west of the chasm, and this place was sandwiched by the chasm and Yingshui, except for Chen Ying, there was nothing to attack, and his army should march to the east of the chasm, attacking the hinterland of our Chu country. ”

There are some differences between Dou Yu Pheasant's judgment and the Operations Division, but it is not unreasonable. If the Huai River is a tree trunk from west to east, then Rushui, Yingshui, Haoshui, and Surabaya are obliquely growing branches. Hundreds of thousands of troops must choose waterways for hundreds of miles and thousands of miles of battles, so that Cai's army corresponds to Rushui, and Chen Ying's army corresponds to the chasm-Yingshui, which is just right into Huaishui. Even if you can't capture Shouying south of Huaishui, you can still sweep all the cities of Zhihua and Zhihua.

Without these cities, the state of Chu would lose at least two-fifths of its Dingkou and one-third of its arable land, leaving only a small half of the Song and Lu lands east of Lishui in Huaishang. If the 800,000 army divides up all the way and attacks Chu along Danshui-Surabaya, then even the Song land west of Pengcheng will be lost, and then only Lu land will be left in Huaishang.

If this is the case, then the Qi State is likely to send troops. The armies of Qin, Wei and Han were devastated, and once the land of Chu and Huai was lost, Qi would not be able to face each other with the Qin army across the Muling Pass. He must at least seize the area south of Jucheng, preferably to Xiapi, followed by Tancheng, otherwise as soon as Muling Pass is broken, the Qi State will die.

“…… Thus marching, and transporting grain in a four-wheeled carriage, should avoid our boat division......"

"Ahem...... cough" Lu Yangjun coughed for a while, Dou Yu Pheasant looked at him, and only after thinking did he understand why he was coughing - the king invented the Bailong waterwheel, which was used less by the Chu people, and the farmers of the Sanjin and Qin countries used it more, and finally used these waterwheels to soak Chen Ying;

Before the invention of the four-wheeled carriage, the Qin army only had a double-wheeled carriage, with a daily loss of 8.8%, a transportation time of 11 days, and a transportation distance of only more than 300 miles, which was not as efficient as a three-person chariot; The daily wear and tear of the four-wheeled carriage is less than one-tenth of that of the two-wheeled carriage, only 0.85%, the transportation time (1/0.85%) is 117 days, and the transportation distance (round trip) can theoretically reach 3,500 li (60 li or 25 km/day).

This is the data of 1.5 tons of grain per cart, if the road conditions and the load of horses are fully considered, each cart can only be loaded with about one ton, the daily loss rate is 1.27%, the transportation time is 78 days, and the transportation distance is still 2,340 miles. Such a long distance can already be transported directly from Xianyang to Yingdu. With the scale of the Qin State's annual surplus of hundreds of millions of stone millet, he didn't care about the losses on the road at all.

The more you do, the more you die, this is the true portrayal of Xiong Jing's inventions. This is also one of the laws of innovation and invention, and it is always the largest that benefits the most, and the non-inventors who benefit the most. Although the giant iron, trebuchet, thorn crossbow, and large-winged warboat were strictly controlled, the changes brought about by them were only tactical, and only the four-wheeled carriage could revolutionize the late transportation system of the Qin army, so that the Qin army had greater redundancy in strategic choices.

Xiong Jing's face became ugly when he heard the four-wheeled carriage, although the four-wheeled carriage was stolen and copied by the Qin people in the Battle of Jiangyi, but this was still his fault. If he hadn't built a four-wheeled carriage, how could the Qin army use a four-wheeled carriage? After the large-scale use of four-wheeled carriages, the Qin army, which had relied on the river to fight, could get rid of the shackles of the river and attack the cities beyond the river, and the grain that would have required more men and horses to transport could be transported by fewer men and fewer horses.

"How much can the Qin people use four-wheeled carriages?" Xiong Jing asked me not to do so.

"About 50,000 vehicles." The four-wheeled carriage has always been the focus of Zhibisi's attention, and there are craftsmen in the Shaofu of the Qin State who have been coerced and bought by them. "Ranchen thinks that the Qin people can't stay away from the river in this war."

"Why, don't the Qin people have 100,000 horses?" Xiong Jing asked, remembering that the four-wheeled carriage needed two horses.

"The Great King." Ezhuo of the Transportation Division said. "50,000 four-wheeled carriages, one cart and three horses, should require 150,000 horses."

"One cart and three horses?" Xiong Jing was surprised, "Isn't it a cart or two horses?" ”

"Definitely. The road is short and flat, and can be used for one car and two horses; The road is long, carrying one ton, it takes three horses, and the road is steep and it takes four horses, otherwise, the horses will die. "Ezhuo is responsible for transportation, and he knows a lot about boat transportation and vehicle transportation." Knowing that the Qin people could not stay away from the river in this battle, this is true.

Hundreds of years ago, only the chariot soldiers fought in armor, and hundreds of people were pawns, and each pawn was only one chariot and one heavy car. After that, the foot soldiers also wore armor, and used crossbows more, and used siege weapons and baggage, and each pawn needed more than 20 heavy vehicles. Now a four-wheeled carriage is used instead of a carriage on land, and twenty people need a chariot. There are a total of 40,000 military vehicles in the 80 major congresses, and only 10,000 are left to transport grain and straw, which is insufficient. ”

E Zhuo's words immediately made Xiong Jing realize that carriages are needed for transportation, and carriages are also needed for camps. The number of wagons needed for the camp was even greater than the carriages for transport.

"An army of 800,000 people, when there are more than 100,000 strongmen, and hundreds of thousands of cattle and horses, the daily cost is not less than that of soldiers. Such an army of 800,000 needed nearly 2,000 tons per day. One cart per ton, the number of horse-drawn carriages arriving at the camp per day shall not be less than two thousand. The grain straw is shipped from Wanjun, Luoyang, and Rongyang, and the schedule is as short as 10 days, and as long as 20 days, a cart of grain arrives at the camp at most 78/10, and the less is only 4/5 tenths. Therefore, the minister thought that if there were no 30,000 horse-drawn carriages for transportation, the Qin army could only travel by water.

The only thing to worry about is that the Qin people gathered 10,000 or more four-wheeled carriages in one place, which could support an army of 300,000 thousands of miles to attack by land. ”

"Chisato?" Not only Xiong Jing, but the others also looked at the map on the wall, and their eyes fell on Da Liang and Shou Ying. If it is himself, if he only has 300,000 troops in his hands to attack far away, he will naturally aim this army at the enemy's national capital.

"Therefore, the minister thinks that the 800,000 army of the Qin people is just a threat, so that the Qi people will also attack me." Ezhuo Road. "With 50,000 four-wheeled carriages, when 600,000 troops are dispatched, 100,000 are sent to contain Chengyang, 100,000 are attacked between Rushui and Yingshui, and the remaining 400,000 troops are equipped with all the carriages, which can avoid our army's boat division, and go south along the east side of the chasm - Yingshui, and directly attack Cai. Under Cai Ruoba, Yingdu shook. At this point, the north of Huaishang and the west of Lishui are not owned by me, and our Chu State has lost nearly half of its national strength and cannot be reinforced. ”

"Zi Zhuo is also ridiculous." Lu Yangjun spoke. "The strategy of the Qin people is very different from the reality only from the transportation of the Qin people. Qin State does not border me except for the western line of Chengyang, if it is really according to the agreement of Qin and Wei, the Qin army will attack the city and the Wei State will gain land, what will the Qin people benefit? The Qin people's every move, every bow and every look is profitable, and the army of the whole country is fighting to the death against me, but they are not allowed to do anything, and they are not wise.

The minister thought that the Qin people would attack me by blackmailing Wei Han. Wei Hanshi died at the hands of our army, or died at the hands of the Qin people, and Qin benefited. Therefore, this battle is not a battle to destroy Chu, this battle is a battle to destroy Chu, Wei and Han. The minister asked the king to send someone to say that he was in Wei and Han. It may be able to send troops, please do not fight with our Chu army during the battle, and our Chu army will only attack Qin's pawns, and will not hurt Wei Han's pawns. ”

Everyone first exchanged their heads and ears, and then nodded frequently. Li He asked: "If the Qin people make the army of Wei and Han fight with me first, and sit and watch, what will I do?" ”

"If this is the case, the Qin people's intention to destroy Wei Han will be fully revealed, and Wei Han's soldiers should turn against and fight in front of the battle." Lu Yangjun said. "If you don't defect, you will die between the two armies of Qin and Chu."

"Will Han Weizhi dare?" Defection is the best, something that is rare in a century, but many people are still worried.

"Han Wei's generals don't dare, but Han Wei's pawns dare." Lu Yangjun continued: "The old minister asked the king to let some Wei soldiers return to Wei, so that he could tell the hometown that the Chu army did not want to fight with the Wei army. If the two armies fight again, those who abandon the army will not be killed or captured. ”

"Good." Xiong Jing nodded in agreement. This is a plan to draw wages from the bottom of the kettle.

"The minister also asks the king to withdraw the army of Magu." Dou Yu Pheasant also spoke. Magu was taken by Xiong Jing as a bridgehead for a counterattack, but this place was really useless, and he had to send 10,000 people to garrison it.

"The minister asked the king to preemptively pull out the recovery of the Qin realm. If the city is restored, the city is worry-free. Dou Yu Pheasant said again. This is not only his proposal, but also the thoughts of all the old people. Once the Qin army loses Fuyi, the west of Rushui will be safe.

Fuyi was the place where Xiang Yan's lone army intercepted the Qin army, as long as Fuyi was controlled, the Qin army could not go east, and could only borrow the way to Shangcai and Daliang in Wei. Xiong Jing asked, "How to pull out Fuyi?" ”

"The minister can lead the army to climb from the south of the mountain to the north of the mountain." Fight in the pheasant road.

"Dare to ask Tang Gong, how did the siege equipment cross Tongbai Mountain?" He asked. The year before last, Xiang Yan retreated to Tang County over the mountains, and for this reason, he abandoned all his baggage, and the soldiers finally even discarded their armor.

"My division will be able to pull out the city." Dou Yu Pheasant does not say the details, and directly says the conclusion. "After our division pulls out Fuyi, it can hold for January, and between January, please send troops to attack Jiyi and annihilate 100,000 Qin troops in Jiyi. After this battle, there was no left west of Hengshan, so I asked the king to seal us in Jiangdong and the people of Yi'an County. ”
