The Zhou army tentatively attacked, and suddenly found that the city was very strong, and the city walls in many places were hewn with mountain stones in the mountains, and the huge stones thrown by the trebuchets could only hurt the skin of the city wall, and it was difficult to collapse it. And across the river, many boulders were thrown over, and they fell into the river without even touching the city walls.

What is even more depressing is that because the Tang army also arranged a large number of trebuchets at the head of the city, they bombarded the Zhou soldiers crossing the river indiscriminately, so that many rafts crossing the river were smashed to pieces. Even the soldiers who were not hit were terrified.

Thousands of soldiers crossed the Han River and began to set up ladders to attack. The arrows and rolling stones of the Tang army on the head of the city suddenly fell down like raindrops, and the soldiers of the Zhou army fell down one by one with a wail, and no one could climb up to the top of the city at all.

After attacking for a while, Li Jing saw that it was difficult to break the city, so he ordered the soldiers who were attacking the city to be withdrawn and set up camp on the other side of the Han River outside the city of Hanzhong.

After nightfall, the Zhou army camp was brightly lit, and Li Jing, Guo Yi, Lin Mo and others began to discuss how to break the city in the big tent. If the Tang army keeps retreating into the city, the plan to quickly capture Hanzhong will come to naught.

And Li Jing knew that as Yuming's master, he had obtained the highest position as a general of the Zhou Dynasty, and many generals were staring at him. If the dignified emperor can't even take a county town in Hanzhong, it is really a bit embarrassing, and he doesn't say anything on his face, which also embarrasses the emperor.

Therefore, Hanzhong must be captured as soon as possible, and it must be won with great pleasure, so as to put pressure on Li Yuan in Chang'an to force him to surrender.

He stood at the gate of the camp, looking at the brightly lit Hanzhong City on the opposite bank, thinking of ways to conquer such a dangerous city. But after thinking about it for a long time, I can't seem to think of any good way.

Guo Yi and Lin Mo also frowned, thinking hard, but they were also at a loss.

Li Jing looked at the map for a while, and then looked at the blue ribbon mark in the center of Hanzhong City, on which was written "Fushui River".

"Dragon, in the middle of this Hanzhong City, the small river that flows down from the mountain is called the Fushui River?" Li Jing asked.

"Yes, the river originates in the Qinling Mountains, passes through the city of Hanzhong, and then flows into the Han water through the aqueduct at the south gate of the city." Lin Mo replied.

"Does that little river have a lot of flow?" Li Jing's eyes lit up and asked.

"The flow of water is not very large, but the terrain here is quite different, and the water flow is very fast. However, the amount of water in the Fushui River in the past two days is not small, because there was a torrential rain only a few days ago, and I heard that the upstream reservoirs were almost washed away by floods. Lin Mo's eyelids blinked a few times. He was a little strange as to why Li Jing was suddenly interested in this small river.

"Then let's go upstream tomorrow to see how things are going. Maybe if we want to break Hanzhong City, we will rely on this frustrated river. Li Jing said with a smile. He already had a preliminary idea in his mind.

The Qinling Mountains are very huge, stretching for thousands of miles, separating the two major regions of Guanzhong and Bashu. Hanzhong City is located at the southern foot of the mountain range. The Han River flows through the outside of the city, and the Fushui River also passes through the city, which can be described as a county town surrounded by mountains and rivers. In the upper reaches of the Fushui River, there are forests that are inaccessible. There are also many mountain streams and lakes.

Early the next morning, Li Jing asked Guo Yi to stay in the camp, and then together with Lin Mo, he led several personal soldiers to climb to the top of a mountain peak in the Qinling Mountains, from which you can see Hanzhong City under the mountain.

"The location of this Hanzhong City is really good, not only choking the only road from Bashu to Guanzhong, but also guarding the road to Xiangyang. If you don't break him, if you want to enter Guanzhong, you can only make a detour from Longxi. Li Jing looked at the terrain and sighed lightly.

Lin Mo also nodded again and again, he looked at the situation in Hanzhong City, but said worriedly: "Great Marshal, the Tang Army has established a fairly complete defense system in Hanzhong City, with many trebuchets and crossbows, and strong city walls. In addition, the city was rich in food and arrows, and the defense was like an iron bucket. Moreover, the terrain here is too dangerous, if you want to attack hard, I am afraid that our army will suffer heavy casualties! This is not to Your Majesty's liking. ”

"Well, I understand! This Hanzhong city is indeed comparable to a fortified city like Luoyang, and it has a unique terrain advantage of being close to mountains and rivers, it is almost impossible to break through if you want to attack hard, and the Tang army has a lot of troops in the city. At present, they are afraid that our army is strong, and they know that they will lose in a field battle with us, so they dare not go out of the city. But we can't keep dragging it out like this, Your Majesty has already explained that we must conquer strategic places such as Hanzhong, Shuofang, and Longxi, in order to force Li Yuan, an old fox who doesn't see a coffin and doesn't shed tears, to surrender...... Therefore, we must find a way to defeat them as soon as possible......" Li Jing said.

Lin Mo was also a little silent after hearing this, everyone understands this truth, but how can Tang Jun be defeated if he wants to. Judging from yesterday's siege, they are also elite troops with strong combat effectiveness. In addition, the city walls are strong and the defense facilities are complete, if you can't hold on, it will be really difficult for the Zhou army to win!

The two continued to walk along the small mountain towards the Hanshui River, and about an hour later, they crossed a big mountain, and a small river in the mountains appeared in front of Li Jing, which was the Fushui River.

However, it is not so much a river as a larger stream, and its water flow is estimated to be only as high as that of the Han River, but because of the large drop, the flow speed is fast, and the torrential rain has only occurred two days ago, and the water flow is not small. Now that the rain has stopped, the river has swelled a lot. The impact is staggering.

The location they are now in is exactly fifteen miles upstream of Hanzhong City, which is a huge mountain canyon, very narrow, only four or five zhang wide, and the water flow is very turbulent and the drop is large.

When Li Jing and the others walked to the boulder at the mouth of the canyon, they heard the roar of the river rushing in the canyon. Above the canyon, there is a dam. It should be built by the government of the Sui Dynasty before the situation to store water to prevent spring drought. It's just that the dam is not very high, only half of the canyon.

After Li Jing carefully looked at the situation at the mouth of the canyon, he already had an idea in his heart. He said to Lin Mo: "Mo, Ben Shuai already has a way to break through Hanzhong City within a month." ”

"Ahh The marshal had a way so soon? Lin Mo was overjoyed when he heard this.

"Well, let's go back and talk about it slowly! This plan must be well arranged so that the enemy does not suspect it. At the same time, we should also pay attention to the evacuation of the surnames in the lower reaches of the Han River! Li Jing frowned.

A few hours later, the two returned to the camp with their own soldiers, and saw Guo Yi greet them.

"Marshal, we have already sent people to the vicinity of Hanzhong City to reconnoitre. I found that there is really no chance to take advantage of it! There was no other way to attack Hanzhong. Moreover, outside the city gate, the Tang army had already dug a trench overnight and introduced the water of the Han River, making it a moat! They also demolished that drawbridge, making it even more difficult for us to get into. Now, even if our soldiers brave the rain of arrows and rolling stones on the city wall to cross the Han River, they will surely suffer heavy casualties......" Guo Yi said with a sad expression.

"This Li Jiancheng is really scheming!" Lin Mo couldn't help but sigh.

"Yes! And that's not all. Our scouts took a closer look and found that there were many traces of new earth in the open space between the moat and the city wall, and it was estimated that there were either pits or tunnels dug under the city walls. There should be Tang Army soldiers hidden, ready to give us a sneak attack from behind when we set up the ladder......" Guo Yi nodded repeatedly. His face was very solemn.

Li Jing didn't answer at this time, but just smiled and said, "Yi, your observation is indeed very careful, and you can see the enemy's defense situation clearly...... Indeed, if we force a siege, we will not only suffer heavy casualties among our troops, but may also be futile. So Ben Shuai thought of another plan......"

When Guo Yi and Lin Mo heard this, they both asked with suspicion: "Does the marshal have a way to break this Hanzhong City?" ”

"No, we don't have to attack Hanzhong City!" Li Jing said with a smile.

"No offense? Could it be that the marshal wants to take a detour? But if you want to go around, you have to go around Tongguan or Dasanguan, which is time-consuming and laborious! Guo Yi frowned.

"No detours!" Li Jing shook his head and said.

"No detour? Does the marshal want to withdraw his troops just now? How can I explain it to Your Majesty? Moreover, if the cavalry of the Tang Army pursues and kills them, I am afraid that it will be difficult for our army to retreat! When Lin Mo heard this, he immediately became anxious. If you withdraw like this. Because Li Jing is His Majesty's master, maybe he will be fine, and they will definitely be scolded to death by Yuming.

"Hehe, I didn't say I was going to retreat! My plan was to exclude the resistance of the Don Army. Two brothers think about it, what is the faster action than building? Li Jing asked with a smile at this time.

After Guo Yi and Lin Mo glanced at each other, Fang said, "It should be destruction!" ”

"That's right! As long as we destroy Hanzhong City! If you think about it, this river of frustration runs right through the city. If there is a great flood, won't Hanzhong City be destroyed? Li Jing said confidently.

"If there is a big flood, it will indeed destroy the walls of Hanzhong City, and the Tang army in the city will also be doomed. However, even if there is a flood, it will only break some houses and floodgates in the city! The city walls will not be damaged much, especially for a strong city wall like Hanzhong City! It's still not going to do anything for us to siege the city! Guo Yi said with some doubts. After all, he had carefully surveyed the terrain near Hanzhong City today.

"Yi, what you said was a small-scale flood, if the scale of the flood is particularly large, wouldn't it be able to wash away the entire Hanzhong City? Imagine how terrifying it would be if the waves of a flood five feet high swept in! Li Jing said.
