Once the Qin army arrives in Lantian, even if the number of reinforcements is only 300,000, the Qin army will face an army of 600,000. The Qin army is not a Qi person who does not want to fight. The 600,000 army based on the elite Qin army can be defeated, but it is difficult to defeat. Once the war is stalemate, more and more Qin troops will be rushed to the pass, and in the end, our side can only withdraw its troops.

Dou Chang deduced the result of the war in his mind, and his heart became more and more urgent. He never felt that time was so precious. This war was related to the old Ying, the Chu State, and naturally the world.

"King, I think..." He spoke, Chengtong, Dou Yuzhi happened to speak, according to the level, and finally Dou Yuzhi spoke. "I think our army should go to Lantian quickly. Only by reaching Lantian quickly can we shock Guanzhong and disrupt Xianyang."

"The cavalry led by Gui Jing has rushed to Lantian." Xiong Jing was also anxious. From today on, the Chu and Qin armies have begun a race. The Chu army took the lead, but after all, they were marching in the enemy area and were in a weak position.

"What I say is from each army and brigade." Dou Yuzhi said. "Our army is controlled by boats and oars. If we wait for the Gongshu Office to clear the Danshui, it will be at least three days later. In these three days, the army has arrived in Lantian."

"Lantian?" Xiong Jing retreated from his mind and said, "Lantian is not Tuheshan. When we arrive in Lantian in three days, where are the armor, grain, and artillery? If there is no logistics and supplies, the Qin army will collapse at once. If it is impossible to capture it for a long time, what can we do? Will we withdraw our troops?"

"I think the army can go for a few days first, occupy Lantian first, and then wait for logistics supplies." Cheng Tong's opinion is similar to that of fighting Yuzhi, but it is more practical. "If you can't attack for a long time, you can wait for the artillery to attack it again."

"What are the boats and oars of each division? Are they docked in the Fengshui?" Xiong Jing looked at the map with thoughtful thoughts. The warship carried soldiers, heavy boats transported military weapons, baggage and food. When abandoning the boats, the warship could only stop on the Fengshui line so that the waterway would not be blocked.

"Yes." It is a passage. "You can send several teachers ahead..."

"No." Zhuang Wudi interrupted. "In addition to the various troops of the Yue people, our army has only more than 100,000, and the Qin people are already waiting in Lantian. We have few soldiers and should not win. If there are many people... Zhulin Pass reaches Shangyi for 110 miles, and then to Shangluo for 210 miles. General Cheng thought that these 210 miles by land would be how many days would it take to reach?"

The military flags raised on the ridge that the Qin army saw did not mean that all these divisions arrived in Shangyi. This was just a blockade of reinforcements that had abandoned boats and landed on the shore after Zhulin Pass. Most of their divisions were still on the warships below Zhulin Pass, waiting for the Danshui to penetrate.

"If you go to the end, follow the two masters and you can arrive in two days." Cheng Tong replied.

"Can you fight after you arrive?" Walking 210 miles in two days was already the standard of the military soldiers of the Wei State, so Zhuang nowhere to ask.

"Not to fight." Cheng Tong shook his head. "You need to rest for half a day or a day."

"How many people are there who are not in the master?" Zhuang Wudi asked again.

"If you stop, follow the Second Division, two-thirds of the soldiers can arrive." They are all military personnel. Everyone knows what Cheng Tong said. Although the combat methods have been changing from ancient times to the present, the way of marching in the infantry has not changed. There is a certain number of miles a large army can walk in a day.

In order to maintain the physical strength of soldiers, they usually march thirty miles a day, that is, one house; if they are long-distance marching, it is difficult to exceed this number; urgent marching can reach one hundred miles or one hundred twenty miles; forced marching is often close to or even more than two hundred miles.

However, the latter two are special circumstances. They can only be occasionally, and mostly small units. Just as the speed of individual off-road is not used to push back the marching speed of the army, the speed of the force-marching of the small units does not represent the marching speed of the army. The more people, the longer the marching column will be, and the longer the soldiers will wait.

A Chu army soldier can take three and a half hours to complete the same road situation; but a Chu army division has to complete these sixty miles, which normally takes five hours. If a division is added to this marching column, the marching time will increase to six and a half hours. If an army (four divisions) are organized into a marching column, the 60-mile journey time will be nine and a half hours or even ten hours.

A soldier who marched for sixty miles and could rest after three and a half hours; an soldier who marched for sixty miles and even if he was not walking, the soldier who carried his armor and weapons for nine or ten hours was still unable to compare his fatigue. Therefore, even on the same road, if he discussed the speed of the march but did not discuss the number of people, it was a standard hooligan.

The reason why Chengtong proposed to go to Lantian first was that the width of the Wuguan Road (which can accommodate several marching columns) could only accommodate two divisions in unison. For every division added to a marching column, the marching time of sixty miles would be increased by one and a half hours. When all sixteen hours a day were filled, the mileage was at its peak.

On the other hand, Wuguan Road accommodates two marching columns, each marching column is one division. If you travel a hundred miles a day, the time required is at least twelve hours (more distances require more rest time). For each division added to the marching column, the marching time will be increased by one and a half hours. Each marching column can add three divisions, that is, eight divisions.

However, 'It takes five hours for a division to march for 60 miles', and 'for every division added to the marching column, the marching time will increase by one and a half hours'. This is only the calculation result of the principle of the B in the plains in the "Guidelines for the Officers of Various Military Branches" compiled by the Operations Department of the Grand Sima Mansion. It is only suitable for the Shangyi to Shangluo section, and is completely unsuitable for the Shangluo section to Lantian section.

According to the on-site investigation of the Operations Department, the road conditions of Shangluo to Lantian sections are only Ding and other places. The marching time of a Chu military advisor is nearly ten hours after walking 60 miles. For every division added to the marching column, the marching time will be increased by two and a half hours. If you do not take the risk of playing the joint attack, the column length will not exceed three divisions at most.

This is actually a factor that is not conducive to the Chu army in this marching race. The Qin army mostly traveled in flat areas, which can be divided into more than a dozen or even twenty marching columns. The Chu army was subject to the terrain and it was difficult for the army to be deployed.

When landing in abolished boats, some divisions and brigades could certainly let some divisions and brigades go first, but because the number of people is too small, it would not make much sense for them to leave Lantian, but the Qin army would defeat them one by one. Even if they went first, they would still have to wait for the subsequent troops in the south of the Qinling Mountains, and then pass through the Qinling Mountains by splitting and joining attacks, or by reducing mileage and increasing marching columns.

The value of landing in abandoned boats is to reduce the time it takes to cross the Qinling Mountains. However, Xiong Jing was worried that the Chu army generals who could not hold back would lead to attack Lantian without authorization and fight with the Qin army before the main force. Winning is certainly a good thing, but if you lose, it is not a good thing.

"How many miles a day for artillery soldiers?" Xiong Jing asked.

"Report to the king, if there are beans, wheat, grass, it can travel eighty miles a day." Zhuang Wudi was shocked when he heard this. He guessed what Xiong Jing wanted to do. "However, this is not the time to harvest millet, and the Qin people did not plant winter wheat. The green and yellow ones were not collected, and the people had no food, let alone horses. Then feed the horses with peppers, and they must fry until half-cooked, otherwise it would be unfavorable for the horses..."

"Is there no peppercorns and corns in the Qin people's warehouse?" Xiong Jing asked unwillingly. The speed of the artillery also restricted the speed of the entire army. He was wondering if the artillery could abandon the boat and land, without waiting for the engineers to clear the waterway.

"Report to the king, there was a news report in the morning that the Qin people were burning the warehouse to prevent our army from eating." Nao Xin reminded.

"What about our army's baggage transportation?" Xiong Jing was unhappy with Naoxin's reminder: "Three hundred miles from Shangluo to Xianyang, and three hundred miles need to be transported by four-wheeled heavy vehicles. Where are these heavy vehicles?"

From the official road from Shangluo to Lantian, we know that the friction coefficient of the four horses had actually measured. The transport heavy truck with four horses could only load one ton, and the daily loss rate increased to 4%, rather than the previous estimate of 2.7%. Therefore, the carriages arrived every day increased from the previous 684 to 833. This is a daily trip of 600 miles, and a daily trip of 60 miles is ten days. A total of 8,333 carriages were required, and the actual number of carriages was more than 10,000.

If these carriages were all in Zhulin Pass, even if only a part of them were in Zhulin Pass, the Chu army artillery could still rely on these carriages to Lantian. But to his disappointment, no one answered.

"Report to the king, carriage, carriage..." Zhuang Wudi finally glared at him and spoke very quickly when he saw Xiong Jing.

"In Jingzi Pass?" Xiong Jing asked again. Seeing that Zhuang Wudi opened his mouth but could not speak, he had to ask, "In Shangmi?"

Shangmi is the intersection of Danshui and Xishui, and it is more than a hundred miles to Jingzi Pass. Unexpectedly, Xiong Jing asked what he said, but Zhuang Wudi still did not answer. He asked again: "Is it a prescription?"

"Report to the king, the carriage and the horse are still between the incomparable yin ground." Nao Xin finally replied.

"Why is it so far away? Where is E Zhuo?" Xiong Jing seemed angry. Although according to the original plan, the lag of the carriage was not fatal, but the carriage was clearly organized behind the front army, so how could it be five hundred miles away? But after a while, he calmed down again - everything was very simple in the war, but even the simplest thing was difficult.

"I will write this down in advance. The Transportation Department must explain to the Buying in the future why the carriage is still five hundred miles away!" He did not give up on this issue because it was difficult for simple things, but wanted the Transportation Department to report the reasons in the future.

"Yi." Zhuang Wudi was already full of sweat, which was also his responsibility. He should have discovered that the carriage was lagging behind earlier.

"Qin people's equipment, Qin army rushes to help..." News from all aspects gathered at Xiong Jing. Of course, he knew that time was victory, but the waterway of the blocked Chu army's logistics was stuck, so he could not move forward at full speed and had to wait here.

Five days, six days, up to seven days. The Qin army led by Li Xin will arrive in Lantian. If you really have to wait for the engineers to clear the waterway, then it will be too late.
