Zhao Guo is really a headache. The army that can fight with the Qin army is probably the Zhao army, but the Zhao country is good, and it will cut down Yan as soon as it has leisure, and cut down Yan when it has leisure. Defeated the Yan State Zhao Congress? There is a high probability that he will not, and he will continue to attack the Qi country.

"The king, the minister thinks that Zhao Guo should not be an alliance, and he will ask for help again in the future, but he can't save it again." Cheng Jiedao. As soon as he finished speaking, Cai Wen, Xiang Que and the others nodded frequently, and the thing they were most worried about was that Xiong Jing was asked by Zhao Guozhi to save Zhao, after all, the Queen Mother was Concubine Zhao.

"He is discussing the affairs of his day, and now Zhao Guo is determined not to cooperate with me?" Nao slyly waved his hand, emphasizing the present.

"Zhao Guoxiang Bang is the Marquis of Chunping, and Mr. Queguan lobbied the Marquis of Chunping every day, but the Marquis of Chunping has no intention of taking this opportunity to seize the East County of Qin." Cheng Jiedao. "Fortunately, the Marquis of Chunping sent all the boats of Zhao State to help me transport grain, and transport one out of ten."

"How many boats does Zhao have in the country?" Zhao Huang asked. Transporting one out of ten means transporting a stone millet from Ao Cang to the temporary granary north of the beam, then you can get a bucket. Of course, in addition to the boat, it is also necessary to carry the force, which is not as simple as transportation.

"Zhao Guozhou is not much, according to the king's algorithm, it is only 3,000 tons." Cheng Jiedao.

"What about Qi Guo? How is the country of Qi? Zhao Huang asked Qi Guo again.

"When the king of Qi talks about Qin, he has changed color, and he has never sent troops to cut the land in the past, let alone today." Seisuke was also disappointed with Qi Guo. Since the five kingdoms attacked Qi forty-eight years ago, it seems that the state of Qi will not fight. "Today, only the state of Chu is not subject to Qin. The minister thought that after this war, he should negotiate peace with the Qin State, otherwise, Qin would attack me, although there was Ao Cang's millet, it would be eaten up in three years. ”

"Great King," Nao Cunning also looked at Xiong Jing, "After this battle, it is indeed time to negotiate peace with the Qin State." ”

"That depends on whether Zhao Guo swallows Yan Di." Xiong Jing smiled at the corner of his mouth. "Those who block the Qin State, except for my Chu State, are the Zhao State. Yan State and Wei State are the same, and often help the state to abuse, even so, the state of Chu should help the state of Zhao to swallow the land of Yan. Zhao Guoqiang is Qin Guoji, Qin Guoji, will attack Zhao instead of me. Zhao is unwilling to take Qin's eastern county, if Zhao is willing to join me and take turns to fight with Qin, Qin will be exhausted. ”

"The king's intentions?" Cheng Jie didn't understand a little, and couldn't figure out whether Xiong Jing wanted to help Zhao or Qin to attack Zhao.

"After Xin Pingjun pulls out the Daliang half of the city, if the river has not frozen, he can transport the trebuchet into the Zhao State by water to help him attack Yan." Xiong Ju said. "The Qin people have both stone armor and chief spears, which are used as sales armor and Zhao State. Otherwise, the Qin army attacked Zhao with a chieftain spear, and the Zhao army would be defeated. ”

"This ......" The ministers looked at each other, Zhao Guo was already short-sighted, but the king wanted to help Zhao Guo and sell his armor.

"King, the Qi State will not want me to sell troops to Zhao." There are some strategies for the flaw, and he is the first to understand the meaning of Xiong Jing. It doesn't matter whether you cooperate with Chu or not, what matters is that you are anti-Qin, as long as you are anti-Qin, then you must support it. "Qi people are unwilling, how can the armor be sold?"

"By sea." Chu and Zhao can only communicate through Qi, geographically speaking, the sea route is the safest, as for the Yellow River to the east, this has to pass through the eastern county of Qin, the waterway is hundreds of miles, it is not safe.

"However, there are only two sea boats in my Chu country." Cheng Jie said, he didn't have too much impression of Haizhou.

"A sea boat can hold 60 tons, a set of giant armor is only 60 catties and 15 kilograms, and it can hold 4,000 sets, and two ships can hold 8,000 sets." Xiong Jing said: "If the armor is thinner, it may be possible to transport 10,000 sets of armor at a time." However, the two sea boats were used for exploration, and the shipyard will build a 400-ton sea boat with a capacity of 400 tons, using the capital pillars dismantled by the Yan Dynasty as keels, which will be completed in about two or three years. In this way, more than 26,000 sets of armor can be transported at one time. It is not surprising that Zhao and Qi should be armed, and as long as they have money, they can sell as many armor as they want. ”

"If the Qin State captures these armors in the future, attack me with armor......" There are still people who are not at ease.

"The Qin people have smelted great iron." There is no need for Xiong Jing to answer, Chengsuke speaks for him.

"The Qin people have refined the great iron?!" Nao Cunning and the others looked at Cheng Jie in disbelief.

"Yes. Zhibisi said that Yan sent craftsmen to Xianyang a few months ago, and Yan Dazi Dan once offered a huge iron sword of Yan State and Qin State veteran Gong Gong, who struck Yan State Sword and Chu State Treasure Sword each other, and Yan Guo Bao sword blade collapsed. "Cheng Jiedao." After the Shaofu fryer, the Qin State did not dare to use the converter to refine the ju, so he had to use the method of the craftsmen of the Yan Kingdom, but this method was very difficult, and it was said that it needed to be practiced dozens of times to get the iron. ”

"It's a hundred refinements." Xiong Jing didn't expect that Yan Guo could really refine a hundred steels, and he also taught Qin Guo.

"What a big deal?" The ministers looked at Xiong Jing again, the iron was refined by Xiong Jing, and only he knew this matter best.

"It's a lot of iron." Hundred steels are the product of carburizing on the outside, and the inside is still iron, but the surface is already steel. "However, the great skill of a hundred refinements is extremely labor-intensive, although a sword does not really have to be refined a hundred times, but it must be refined more than a dozen times. The same is true for the giant armor, each piece of armor has to be tempered more than a dozen times, which is very expensive. ”

"In this case, it should not be sold to Zhao State." Zhao Huang Road. "If the Zhao army is defeated, Jujia may fall into the hands of the Qin people."

"Zhaoqing thinks that the Qin people can't afford to use a hundred refining irons?" Xiong Jing sighed. "The Qin people can afford to use the stone armor, how can they not afford to use the Hundred Refining Giant Iron? The whole army naturally can't wear armor, but there is no difficulty for 100,000 soldiers to wear armor in the Qin State. Sell huge armor to the Zhao army, the Zhao army can kill one more Qin pawn with armor, and the Chu army will have one less enemy, why not?

The state of Chu is not to send soldiers to the state of Zhao, but to sell soldiers to the people of Zhao. Zhao Guo needs to pay in horses and large seals. Prairie horses cannot be used for riding, but can always be used for retraining. Dazhang can be used for shipbuilding, Zhao is located in the east of the Taihang Mountain, there are many giant trees in the mountain. If King Zhao can be like Chu State, dismantling the dynasty and sleeping in the right place, it will be even better. ”

After taking Aocang, there was no shortage of grain for the time being, but Ma and Dazhang were still the things that Chu State urgently needed, especially Dazhang. The large-wing warship is forty tons, and the reinforced one's wings are only sixty tons (because of the weight of the horses, it may actually reach seventy tons, resulting in an increase in draft), minus five hundred large-wing warships, the Chu army still needs more than seven hundred one-wing warships, and seven hundred is forty-two thousand tons.

The structure of the war ship is simple, and the same tonnage consumes only two-thirds of the wood of the sea boat, and even if it is two-thirds, it will be 28,000 tons. The relationship between tonnage and the volume of timber is, according to the oldest law known to the bear, to be based on logs, which is equal to the length of the ship multiplied by the width and then multiplied by the height.

It's just that this algorithm is still not clear, and the 74-Gun standard gunboat, which the British had a displacement of one thousand and thirty tons, the required amount of wood for it was three thousand and fifty timber (that is, loads. The wooden unit used for shipbuilding, one load is equal to 50 cubic feet), which is equal to 2,000 oak trees with a diameter of more than one meter at breast height, and the Spaniards' 2,000-ton Galen ship also consumes 2,500 large trees. Basically, it takes 1.25 100-year-old medallions to drain 1 ton, and 35,000 trees to drain 28,000 tons.

The number of war boats of the light boat division is even more so, and the sea boat will be even more so, with a load displacement of more than 500 tons for 400 tons, and 110,000 tons for 200 ships, which will require nearly 140,000 large trees. With the dense forests of Chu State, there are Dazhang, but it is not easy to enter the mountains to cut trees, especially how to drag out of the deep mountains after cutting, it is even more problematic.

Steel may be used as keels and ribs, but because there is no flat, sufficiently wide rolling mill roll, there is no sufficiently wide iron sheet for shipbuilding. It is also possible to forcibly build it, but people who don't know the inside story will definitely think that this sea boat is made of countless pairs of ring armor, and the number of rivets on it will be astronomical.

The state of Chu, which is short of materials and manpower, must trade with other countries to make up for the shortcomings, and it is not enough to just be the state of Qi, and it is necessary to add the state of Zhao, the state of Wei, and the state of Zhuyue in order to barely meet the needs. After Xiong Jing finished speaking, the strategy of helping Zhao was basically set, but it was impossible to save Zhao, and if Zhao faced the attack of Qin in the future, he could only deal with it alone.

After discussing the matter of cooperation, there is another more important thing that is the road from Yingdu to the Yangtze River. After experiencing the incident of the granary of Putianze, Xiong Jing no longer dared to insist that the railway must be built, but listened carefully to Chengjie's idea of the Yinglu Canal.

Yingdu is Yingdu, and Lu is Luxian (Hefei). Yingdu communicates with Huaishui, Luxian connects to Chaohu Lake, and the water along the southeast of Chaohu Lake can enter the Yangtze River. The problem now is that although the water that flows into the Huaishui in the north and the water that flows into the Chaohu Lake in the south are the same mountain (now Jiangjunling), this mountain is the watershed between the Huaishui and the river, and all the water in the north of the mountain flows into the Huaishui, and the water in the south of the mountain flows into the Yangtze River. The mountain is not high, but it is impossible to open a river here.

The solution is to open another ditch in the low-lying area to the east of the watershed, so that the water flowing south to Chaohu Lake flows backwards to the north along the low-lying terrain, and the second is to raise the water level of Shaobi, so that the water of Shaobi meets the water flowing backwards to the south. With the help of the existing waterway and topography, the length of the ditch is about 80 miles, and only half of it needs to be excavated; Raising the water level of Shaobi is just to raise the height of the water outlet of Shaobi, and the project is not complicated.

"How many years?" Xiong Jing asked, "After the opening, can I still sail when there is a shortage of water in autumn and winter?" ”

"It can be done in two years." Seisuke replied that this was the estimated time. "When there is a shortage of water in autumn and winter, you can also go boating, but you can't take big wings, painting boats, and big boats, and you can only take small boats such as Qinghan boats."

"How about building a few locks?" Xiong Jing naturally thinks of the locks. The advantage of the lock is to raise the water level, as for the opening and closing of the gate, you can use manpower, animal power, but it is better to use a steam engine.

"Boat locks?" What everyone has heard, the lock was called the steep gate in ancient times, and it first appeared in the Tang Dynasty, and the steep gate on the Ling Canal was built in the Tang Dynasty.

"It is to set up a gate in the shallow water, to store water in the gate, if the water level gap is not large, the gate does not need to be closed, and the side can open a small door that can pass through the boat; If the difference between the upper and lower water levels is too large, then the floodgates should be closed. If the low-water level boat wants to enter the high place, it must first enter the lock chamber, and then open the gate for navigation after the water is raised. ”

Xiong Jing drew a sketch, and those who didn't understand it were fine, and a few courtiers who understood couldn't help but shout that the king was wise. Narisuke was also overjoyed, and if such locks were built, the canal would be able to pass through the Wing and the Boat throughout the year, and even sea boats would be able to enter the river and go out to sea here.
