"Master, Wei will not help me only by the interests of Wei." Zhou Wen said bluntly. Although he could not fight, he defected to Chen She as a general at the end of Qin and entered Hangu Pass but was defeated by Qin general Zhang Han. However, based on his understanding of Wei, he could still make a more accurate judgment. "The alliance of Qin failed to attack Qin, and several countries of Chu, Zhao, and Yan retreated and became safe, without any loss, but this Wei..."

"Only this Wei State lost Chaoge first, and then Ji land. This year, I may lose the three cities of Yuanyi, Puyang and Yanyi." Huang Xie said. After Hezong, Qin did not attack others, but only attacked Wei State. This spring, county troops were launched again, trying to seize Yuanyi, Puyang and Yanyi. Shen Yin and others believed that Wei State was repeatedly attacked by Qin, and it would be inevitable that Hezong would follow.

"That's right." Zhou Wen nodded. "For four years, the kings and ministers of Wei have only wanted to truce with Qin to resolve peace with Qin to prevent the anger of the last united attack on Qin. If the people attacked Qin again, wouldn't the Wei State lose the city again?"

"How about Zhao State?" Huang Xie talked to Zhou Wen, and Yu Qing seemed to be wandering outside, absent-minded, and Huang Xie had to ask.

"Is the Lord asking me?" Yu Qing came to his senses. Although he was Huang Xie's disciple, he was usually free and easy and had little effort. This time he was summoned by Huang Xie and went to the meeting to discuss. "Dare to ask the Lord: Chu and Zhao, Chu saves Zhao, who has seen Zhao saves Chu?"

As soon as Yu Qing spoke, Li Yuan smiled. Wei and Zhao were not aligned with Chu, and Han Yan had no chance. The matter of the prince entering Qin was decided. Once Xiong Jing entered Qin, Qin would really make it impossible for him to return to Chu as agreed, and his nephew would be the next King of Chu.

Li Yuan smiled, and Huang Xie refused to give up and asked: "The two countries of Chu and Zhao depended on each other. Qin attacked Zhao several times and was saved by Chu. Moreover, the eldest son Jing is the son of Zhao Concubine Zhao and the younger brother of Zhao. If he is the king and Zhao is beneficial to Zhao, why don't Zhao save Chu?"

"The lord doesn't know something." Yu Qing felt a little serious. "Now, our Chu king is not a brother of Zhao. Chu also sent troops to rescue Zhao. The king's eldest son ascended the throne in the future, and it will take more than ten years to rule. The Chu king's policies are all in the lord, so what does it have to do with the prince?

The Qin State's desire is a proton. Although it is the eldest son, the eldest sons of Han, Yan and Wei are all in Xianyang. Why do they make great wars for the Chu State? Although the eldest sons of Han, Yan and Wei are in Xianyang, the three kingdoms still unite to attack Qin. What is the proton?”

Yu Qing asked repeatedly, which surprised Huang Xie. The communistence began in the Spring and Autumn Period and the Zhou and Zheng periods, and by the Warring States Period, it had become a formality. The monarchs of various countries had several princes under their knees. Even if they condemn the priests, they would not take into account the security of the protons and truce with other countries. Although other countries had protons, they did not dare to use this as a threat, for fear that the other party would change to establish another heir and would embrace the empty priests.

"According to Mr. Yu Qing's intention, Zhao State will not help me this time?" Zhu Guan listened carefully to Yu Qing's words and asked.

In August, Yingdu was held frequently and there were rumors. The Prince's East Palace inside the Lumen seemed to be out of the matter and was not affected at all. Some of them were "strange roads" paved around the entire palace after spending more than ten days:

Each of the woods about four or five feet long was discharged parallel to each other at a distance of about two feet, wrapping the entire Eastern Palace around. Above the wood, near the edge are two iron bars. The gap between the iron bars is more than three feet, neither wide nor narrow. The wheels of the four-wheeled carriage above just block the iron bars. Once the horses on both sides of the road are dragged, the wheels roll forward along the two iron bars.

This is a railway, and people with a little common sense in later generations can tell at a glance, but in the State of Chu more than two thousand years ago, this was a completely strange thing.

"... Using iron bars as the road, chariots and horses are placed on the road, and the car is loaded with heavy loads..."

The historians around the King of Chu recorded their words and deeds, and the prince also recorded their stories. The historians around the King of Chu were relatively relaxed, so the prince was different here. Whenever he created any new things, the historians responsible for recording would be cut off.

"Your Highness, is this the railway?" Gong Yindao's eyes followed the frames driving on the iron bars until they turned to the other side of the palace.

"It's not considered a railway." Xiong Jing shook his head, "At most, it is a horse-drawn railway. Only by developing the power of water and fire and driving the carriage with the power of water and fire can it be considered a real railway. At that time, a truck can hold a huge amount of four or five hundred tons."

The concept of tons of worker Yin Dao is well known. Generally speaking, one ton is equal to four thousand Chu jin, and five hundred tons is two million Chu jin. A railway truck can hold two million jin, and the back groove of the worker Yin Dao was exposed.

"Your Highness, even if it is a horse, it is still amazing." The person who spoke was the emperor of the Yu Mansion. Three four-wheeled carriages were loaded with six tons of goods, and they walked around the entire East Palace under the drag of two horses. Only then did the four-wheeled carriages truly realize their capacity.

"It depends on whether the bearings you make are reliable." Xiong Jing replied. Unlike ordinary carriages, these three carriages use bearings carefully made by Yufu. However, the quality of the bearings is still unclear. The carriage has been turning more than ten times, and it is faster and faster. When the counting temple people shouted thirty times, they turned to the carriage behind the palace and did not return to the south starting point for a long time. The temple people ran over and ran back, "Report to Your Highness, Yushou said that he would not turn for a long time."

Yu Yin was very ashamed when he heard this, so he ran over to look at Xiong Jing. Xiong Jing had no reaction, and bearings were not so easy to make. Although there were craftsmen who made exquisite objects in the Yu Mansion, he also drew the bearing structure diagram and made a vernier caliper, it still took a long time to accumulate experience.

"Your Highness, if there is no power of water and fire, just use horses to pull, how much can you transport things?" Seeing Xiong Jing did not move to see the broken carriage, Gong Yindao asked about the horse-la-rail railway, wanting to know how effective the horse-la-rail railway is.

"Just just use horses? One or two hundred tons." Xiong Jing replied. He remembered that during World War I, the Russian army's horse-drawn railway, the theoretical maximum transportation volume of 100 Russian miles per day and night was 500 tons, and the actual average transportation volume was around 180 tons. To reach 500 tons, three pairs of trains were required, and each train had 100 cars. In total, each section could only carry a pitiful 1.66 tons.

This is obviously too few. Even without railways, each four-wheeled carriage can be loaded with 1.66 tons. However, considering that it is in wartime, to reach the wartime statistics that pave 2.88 kilometers of horse-drawn railways every day and night, the slope limit is very wide. If the normal slope limit of the railway is based on the railway, two horses should be towed at least three tons. If this is the case... Xiong Jing was shocked. If each carriage is loaded with three tons and three pairs of trains, the horse-drawn train every day and night can transport 900 tons of cargo.

The transportation volume is very large and the construction cost is not expensive. Even if you use 7.25 kilograms of railway tracks per meter, plus nails and other items, you will need sixteen or seven tons of steel per kilometer, which is worth more than one thousand gold. It is not counted as civil engineering, bridges, facilities along the way, and vehicles. With the annual fiscal revenue of the Chu State, it cannot be built for 100 kilometers of railways, which is really too expensive.

Even if the converter can produce steel, the steel price will be reduced to the ideal ten cents per catty, and the construction cost of 16 tons of steel will cost 133 gold. The only thing that can afford is that there are iron wooden rails, but iron wooden rails also require iron, one kilometer per meter and two tons of iron consumed per kilometer, and it will be calculated that it will not be less than four gold.

Yu Yin did not come back after he went there. After Xiong Jing thought about the cost of the iron wooden rail outside, he no longer thought about the broken bearing and went straight into the hall to see the map of Chu. What he thought was: Given the current situation of Chu, how should the railway be built?

In terms of military and economic terms, it is necessary to connect the Lu area in the northeast, the Song area in the middle, and Chen County, Pingyu and Chengyang close to the Wei State. This area is the most densely populated area in the Chu State, but because the Ru River, Ying River, and Pu River flow all flow from north to south into the Huai River, the route of vendors is generally to go downstream, enter the Huai River from west to east, and then transfer from the Huai River to other rivers, and go upstream. Even if you go downstream, the journey will take more than half a month, and the time from east to west will be longer.

If all the cities upstream of these rivers are connected by railways, then from Ludi at the northeasternest end to Chengyang at the westmost end, it will take three days and within three days. If you only travel during the day, it will only take six or seven days.

In terms of military affairs, the significance of this railway is to allow the State of Chu to mobilize soldiers across the country as quickly as possible. For example, when fighting against Qin, it takes at least one month to reach the army's assembly without a railway, but if there is a railway, the mobilization time will not exceed ten days. When the Qin army was not fully assembled, he was caught off guard, eliminated some of the main forces of the Qin army, and occupied some important cities and passes in the Qin State, so that subsequent wars would be easy to fight.

If: more than 300,000 troops of Chu took advantage of the Qin army's full strength to attack Zhao State, they gathered to the border of Chengyang within ten days, and then quickly captured Dan (now Zhejiang and Sichuan) and Xi (now Xixia, Henan) under the Dan River with their military strength. Then, with geographical advantage, they fought against the Qin army that had been attacked by the whole country for several months, and the Nanyang County of Qin State and Nan County - all the territory lost by Chu State from the Battle of Chuisha can be recovered.

"Zijing..." Xiong Jing, who thought of using the mobilization advantages brought by the huge railway transportation capacity, was a little excited. He didn't want anyone to call him behind him, and he was a stern Guanzi.

"Greetings to the teacher." Xiong Jing hurriedly gave the disciple's greeting.

"How is Zijing trying to restore the old land of Chu?" Ziguanzi was still a feathered hat with undressing edges. He saw Xiong Jing's fingers stroking on the Dan and analyzing the two towns. He knew very well what these two towns meant.

Since the founding of the State of Chu, it has always attached importance to the defense of the north, so it built Fangcheng at the junction of Nanyang County of Qin and South Korea. The name of Fangcheng County in later generations came from this. The Battle of Chuisha in 302 BC caused the State of Chu to lose the entire Fangcheng area (Nanyang County of Qin). Four years later, in 298 BC, King Huai of Chu died and King Xiong Qingxiang of Chu ascended the throne. Qin failed to extort and launched troops to attack Chu, and then captured the sixteen cities of Xiyi.
