About an hour later, a floating bridge was put up. At this time, it was the second quarter of the fifth night. Tian Yu looked at the army standing by behind him, waved his hand and said, "go on, light the torch, and the army will cross the river!"

At his command, a group of taxi soldiers came out of the army. Each group was armed with a torch by the commander of the army. They formed several teams and walked toward the other bank.

Soon, the five thousand soldiers had crossed the river. Under the guidance of the shadow guard, they headed south of the ferry. They had to build a defense formation in the south of the ferry before the Qin army's sentry arrived.

Five thousand cavalry soldiers followed the first school soldiers, followed by crossbow soldiers and soldiers from another school. After the main army had crossed the river, five thousand people and their food and grass were the last to cross the river.

As Tian Yu had expected, the cavalry had only passed more than a thousand years, when the Qin army's patrol found that the army was crossing the river. Soon, the arrows sounded on the West Bank of the river, and then the three pillars of wolf smoke rose several miles away in the south of Longmen ferry. At this time, the sky was completely bright. A round of red sun rose from the East, and the three pillars of wolf smoke were immediately seen by the guards in Xiayang city in the south.

The Qin army in Xiayang city was immediately busy. The alarm bell sounded at the head of the city, and teams of soldiers in armour ran out of the barracks around the city with guns and ran toward the city where they were defending.

A moment later, Xiayang guard General Li libian appeared at the head of the city. At the same time, after the South Gate of Xiayang city was opened, more than ten red Ling messengers raced out of the city, and then divided into several teams and ran in several directions.

However, what surprised the sentinel cavalry of the Qin army was that after the Tang army crossed the river, they only stood in array in the south of the ferry, but they didn't plan to attack half of them. Even the thousands of cavalry who had crossed the river didn't mean to chase themselves. They just stood quietly behind the infantry square.

In less than two hours, Duan Lu, the left Fengyi prefect of the state of Qin, got the news that the army of Tang had crossed the river. Duan Lu was very surprised when he heard that he ordered to warn Wang Du, and at the same time ordered 5000 Xiliang cavalry to assemble urgently. Under the leadership of Du Wei and cavalry general Niu Jin, Duan Lu went to Xiayang and left.

What Duan didn't expect was that the cavalry came back less than an hour after they left. The news was that the Tang army had led the army northward along the West Bank of the river, with a total of 30000 troops. When they left, they destroyed the already built pontoon, and the five iron ropes of the Hengjiang River were taken back by the Tang army in the east of the river.

Hearing this news, Duan Leng was relieved. At the same time, he felt a sense of vigilance. The defense of Longmen ferry must be strengthened. No, it should be said that it has been established. If the Tang army can cross the river once, it can cross the river twice and three times. If Tang Jun meant Feng Yi this time, he might be caught off guard.

Thinking of this, Duan Leng immediately ordered Xia Yang's General Li Li to follow the Tang army and confirm that their army had left Feng Yi. On the other hand, he immediately sent someone to set up an army formation on the West Bank of Longmen ferry and sent 1000 soldiers to defend the ferry day and night to prevent the Tang army from crossing the river again.

If Huangfu Chaobo knew what Duan Lu was thinking, he would scoff. If he wanted to invade Feng Yi, he could cross the river in many places. Moreover, after seizing Shangjun, it was almost easy to attack the state of Qin.

When Tian Yu led 30000 troops across the river, Huaxiong had already led the rest of the troops to the north of caisangjin. Together with Huaxiong army, there are 10000 craftsmen and 100000 stone grain.

Taking advantage of the opportunity of attacking Shangdang last year, the whole Shangdang road was almost repaired. In particular, several roads that are very difficult to walk on weekdays, such as the roads between Duanshi, Beiqu and Puzi counties and the cities in the hinterland of Hedong, were all renovated last year, which made Huaxiong's army move very fast.

……

In dingyang City, the day after Tian Yu's army crossed the river, all the people in Shangjun had already received the news. When they learned that there were only 30000 Tang troops crossing the river, they were very happy. Fazheng is not as optimistic as the three players. Now they have completely lost the information in the direction of Hedong, so they know nothing about the movement in the direction of Hedong.

But Fazheng knew that there could not be only these soldiers and horses in the Tang army. According to the news from Chihou, the army of Tian Yu had only 20000 soldiers, 5000 cavalry and 5000 men. That is to say, they only had enough food and grass for the 30000 people in a month. Now Longmen ferry should be under the control of the Qin army. Therefore, the Tang army must want to transport troops and horses from caisangjin to support the next war.

Just as Fazheng expected, three days later, news came back from Hukou town that tens of thousands of Tang soldiers appeared on the wharf on the East Bank of caisangjin opposite. The number should be between 40000 and 50000. There are thousands of wagons alone.

"Generals, the war is about to begin!" FA Zheng looked at the East and said to the three men;

"military division, do we really need to send troops to intercept Tian Yu's army halfway?" "The road on the West Bank of the river is not wide, and the army of Tian Yu is at the vanguard of 3000 cavalry troops, and the soldiers are closely escorted by the logistics convoy. We hardly have any chance to threaten the army of Tian Yu, so we don't want to put our time and energy on the defense of Hukou town." Fazheng shook his head;"General Hengye, has general Xu Huang arrived at Hukou town?"

"I just got the news in the morning that Xu Huang had led the army to Hukou town. Now he has taken over the defense of hukou." A few days ago, after discussion, several people sent 1000 soldiers to Hupin town to strengthen their defense. In this way, Hukou town had 5000 soldiers and 4000 cavalry. Their purpose was to use hukou to kill Tang soldiers as much as possible.

Unfortunately, from Hukou town to dingyang, there is no place to build a territory, and the last few years, the king, has not built any defensive buildings in the valley, such as the pass army formation. Therefore, there is only a gully about 100 Zhang wide between dingyang and Huguan town.

In fact, several people have thought about building one or two of these passes, but even small passes can't be built in ten days and a half months. The most important thing is that the remaining one is the king. He doesn't have so many building materials. For example, the reason why Chen Gong was able to build Nanguan within ten days of the Tang army's attack last year is that Nanguan was already an existing pass, Zhao Jun only needs to repair it. Another thing is that they carry a lot of building materials in addition to 10000 people. Only in this way can they have such speed and efficiency. However, none of the two conditions are available now.
