As Fazheng expected, Qin's current attention is entirely on Ma Teng and Han Sui in the west, and on Tang in the East, although they are also paying attention, they don't pay as much attention as the three players in Shangjun. Of course, this does not mean that the state of Qin paid no attention at all.

As early as the mobilization of the Tang army in Hedong, the secret agents of the state of Qin had already received the news, but Li Ru believed that with the wisdom of the emperor and his ministers of the state of Tang, they would not do such a thing that would harm others and harm themselves. Now the war in the west of the state of Qin has not yet begun. If the state of Tang suddenly sent troops to the state of Qin, it would be a mistake to beat the state of Qin, but it would only be cheaper for Ma Teng and Han Sui.

However, Li Ru did not place his hope on the enemy either, so when he sent troops to block the United forces of the two Koreas a few years ago, he deployed heavy troops in the cities along the river in the east of Feng Yi. From the northernmost Xiayang and Yingyang to Linjin, ten thousand soldiers were stationed, and even five thousand soldiers were stationed at pubanjin ferry. At the same time, five thousand Xiliang cavalry were stationed in Linjin.

Although there was only a narrow road for the Tang army to reach Xiayang from Longmen ferry in the northernmost direction, the Qin army only needed to guard Xiayang city to block the road for the Qin army to go south. However, Li Ru ordered the Qin army of Xiayang city to go north every day to patrol between Longmen ferry and Xiayang city in case of accidents.

However, neither Li Ru nor the generals of the state of Qin expected that the Tang army could cross the ferry overnight, and then built a floating bridge overnight. By the time the patrol of the state of Qin found out, the Tang army had 5000 soldiers crossing the river and formed a formation in the south of Longmen ferry.

In fact, at the beginning, Tian Yu had thought about crossing the river in caisangjin, but after several observations, he found that the remaining soldiers were the king. They almost visited the West Bank of caisangjin day and night, and it was almost impossible to cross the river smoothly without disturbing them. On the contrary, he denounced Hou Congqin's patrol and found the defense loophole of Longmen ferry.

On February 19, the 15000 troops of Huaxiong department in Hanoi, the 10000 troops of Shegan department in Hongnong, Pang Tong and his 5000 guards all arrived at Pishi. Tian Yu gathered all the generals in the barracks outside Pishi city to discuss and decide on the strategy of sending troops.

"Ladies and gentlemen, I have been wrongly loved by the king and appointed the general to be the chief General of the western expedition. I hope I can work with you to open up the territory for the king in the next war." Above the throne, Tian Yu said to the generals;

after hearing the words, they all stood up and said, "we will certainly live up to the king's trust!"

"Well, after consulting with the military division, I decided to divide the troops into two groups. One group of troops crossed the river from Hejin, carrying half a month's grain and grass, and then went north along the river; the other group of troops continued to go north from Hedong to caisangjin. After the soldiers and horses in Hexi control the ferry on the West Bank of caisangjin, the two sides cooperate to set up the floating bridge, and then transport all the soldiers and horses' grain and equipment across the river. "

"There should not be too many troops and horses to cross the river. After consulting with the military division, the general decided that I would lead two schools of infantry, one school of crossbow and one school of cavalry of the Yingyang army, and five thousand men would transport the grain and grass of the army to cross the river. The rest of the troops and horses would be led by Huaxiong general all the way north along the official road to the East Bank of caisangjin to prepare for crossing the river."

Hua Xiong rushed out to receive orders, and then he asked: "do not know how the general cross the river?"

"General Hua, please don't worry. In the past few days, nearly ten people of the water army and shadow guard have quietly crossed the river through various ways. Now they are all hidden in the mountains to the west of Longmen ferry. At that time, we only need a boat to cross the river and pull up the rope that has been prepared. For our Tang army, it's easy to build a floating bridge The time bridge can be built in two hours, and then 20000 troops and horses can cross the river in two hours. "

After listening to Tian Yu's arrangement, everyone was relieved. Since Tian Yu had already arranged it, they didn't say any more.

"After I led the army to cross the river, the rest of the troops were led by general Hua Xiong to the north to caisangjin. The reason for this arrangement is that it was so arranged. One reason is that it is easier to cross the river from Longmen than from caisangjin, and the other is that it is safer for the army to cross the river from caisangjin. According to the flood season of the river over the years, the peach blossom flood will last until the middle of March at the earliest, and it will last until the middle of April. Therefore, we must transport the grain and grass of the army for nearly two months across the river as soon as possible. In case we can accumulate the grain and grass of the army for three months in Shangjun. "

"General Tian, please rest assured that general Ben will transport the grain and grass needed by the army to caisangjin as soon as possible, and then cooperate with the general to transport all the grain and grass across the river as soon as possible." Hua Xiong got up again and said,

originally, among the three generals, Hua Xiong should be more qualified, because after all, he was captured and surrendered by Huangfu Chaobo when he sent troops to attack Dong Zhuo, and the three generals were all the first battalion generals with the same rank. However, Huangfu Chaobo insisted that the younger Tian Yu be the main commander Although Huangfu Chaobo also sent Pang Tong as a military adviser, Tian Yu was appointed as the chief General after much consideration.

At the end of the discussion, the departments and armies began to prepare separately.

At the beginning of the fourth shift on the 20th, Tian Yu, escorted by his own soldiers, came down to the East Bank of Hejin Longmen ferry. At this time, the sky was completely dark, and there was no light on the other side of the river. As for the wharf, Tian Yu ordered: "Send a signal to the other side."Soon a soldier came out of the crowd, came to the dock, raised a torch, drew three circles in time, and then drew three circles in reverse.

Before long, a torch appeared on the opposite bank, just like on the East Bank of the river. It drew three circles on both sides, and soon a fire started on the other bank.

"General, the opposite side is ready!" One of the generals happily went to Tianyu road;

"ordered the navy to start crossing the river and prepare to build a floating bridge."

"No!"

Soon dozens of Tang soldiers pushed out a wooden raft and carefully placed it on the unruptured ice. Then ten soldiers quickly climbed up the huge raft and tied a bundle of rope to it. Ten people sat on both sides. With a light cry, ten people supported the raft on the ice with their hands wearing fur gloves, and the raft slid toward the other side of the river.

Under this operation, the wooden raft with ropes slid toward the bank. Rao Shi tried his best to paddle the raft, and it took half an hour to slide the raft to the West Bank. The Tang soldiers who had been ready on the bank immediately took the taxi and pulled the raft onto the bank.

Then he tugged at the rope on the raft. A huge iron rope was tied to the other end of the rope on the raft. After pulling the iron rope over, the West Coast taxi soldiers fixed one end of the iron rope on the bank. In this way, all the five cables were fixed. After the five cables were fixed, some people began to install the prepared wooden rafts on the cables.
