After ten days of travel, in order to leave enough military camps for the subsequent army, Liu Yi walked for thirty days. At this time, Liu Bei's main army was almost halfway.

He stole a handful of clear water and poured it on his face. Liu Yi looked around and felt like he was surrounded by mountains, but there was only one mountain away from the Hanzhong Plain.

"Sir, after crossing this mountain, it is the Hanzhong Plain, which is only thirty miles away from Nanzheng." Guan Ping came to Liu Yi with a knife and took a breath. The weather gradually became hotter. The air in Hanzhong was filled with stuffiness, which made people feel uncomfortable.

"Can this water reach?" Liu Yi wiped his face and looked at Guan Ping and asked.

"I asked the guide, but I can't go, I have to walk a while." Guan Ping shook his head: "Maybe it is slower than taking the land."

"No matter what, the war is your business. Moreover, the siege equipment must be transported by water. One hundred soldiers will be assigned to the camp. You can lead the team, just be simpler. The most important thing is to prepare enough wood and dry some. After we join the lord's army, we will go to Nanzheng and Wenchang's side. We should have almost started to do it. Send a few people to find out if there are any large armys coming to Mianyang for support recently. By the way, check out Nanzheng Xushi. This battle is best to go down in one battle and break through Nanzheng. Everything is easy to say, but it is not easy to defeat. Remember, be smart."

"Here!" Guan Ping agreed and turned to make arrangements. Liu Yi began to take some artificial vehicles to transport things. After attacking the Hanzhong Plain, the grain and grass were sent directly from Jiameng Pass to the front line. This road was invalid. But the current problem is whether the military rations they carried could last until the first batch of grain and grass to be transported here. Although the road and meeting place had been determined in advance, and the person who was escorting the grain and grass was also personally escorted, there would always be an error. Liu Yi was a little worried and asked Huang Zhong to send someone to pick up Liu Feng. Don't make any mistakes, at least the error should not be too large.

Logging and then building several transport ships is not a difficult task for Liu Yi today. The next attack on Nanzheng is the highlight.

Liu Yi calculated that first, Wei Yan had to successfully attack Mianyang and occupy Mianyang. Then Zhang Lu had to raise troops as soon as possible to attack Mianyang and draw some of the troops in Nanzheng area over. It was impossible. Zhang Lu was not that stupid either. Then, it depends on the speed of attack here. Liu Yi now considers other siege equipment besides building ships.

The main siege equipment is not a catapult, a bow, an arrow, and the most important thing is a ladder. The so-called ladder is not a simple ladder on TV in the previous life. The defenders in the city took something out and pushed it down. In fact, as early as the Spring and Autumn Period and the Warring States Period, the public sending team had invented a ladder. There were wheels at the bottom and could be moved, so it was also called a ladder. The ladder could be swung up and down through manpower. One end of the ladder was equipped with a barb. Once it hooked the city wall, it would be difficult for the soldiers in the city to push the ladder away.

There is no shortage of drawings for ladder trucks. Liu Yi had already started researching them when he was in Jingzhou and tried to make several.

Regardless of the attribute level, most of the attributes appear are stable and solid. Occasionally, some attributes that increase courage will appear, but they are rare.

But one thing is, the ladder is a bit annoying. Unlike the fire trucks in later generations, the ladder is one and not very convenient to carry. Liu Yi followed the method of the fire truck and changed the ladder to a combination of two ends. There is a winch in the middle. Half of the ladder can be fixed, and half can be adjusted up and down through ropes and pulleys, and no need to carry up and down with manpower.

In addition, there are changes on the chassis, where people can be hidden inside, and the body of the car also has protective baffles, which can protect the soldiers in the car from harm during the arrival. At the same time, there are fixtures on the chassis. Once you arrive at the city, after opening these fixtures to fix the body, the body will be more stable and there is no need for someone to help.

This was designed by Liu Yi according to the structure of the fire truck, but the ladder body cannot be followed. The friction between the wood is too great, making it difficult to slide freely like a fire staircase. Moreover, the main staircase is fixed, and the secondary staircase must be adjusted according to the height of the city wall, and it cannot be like a fire truck. Therefore, Liu Yi designed it with a bearing connection and a folding structure, which can maximize the time to build a ladder.

Liu Yi has not yet accurately data on the scale of Nanzheng, but with Liu Bei's troops, it is rare to siege a county city. Therefore, Liu Yi is preparing to design a ladder according to the budget of a city wall to attack. There must be twenty such ladder cars, at least so many, and then they have to cooperate with the well railing, which is similar to a mobile hanging bucket. When people stand on it, they are basically level or even slightly higher than the city wall. Archers launch an attack on the defenders on the city wall through the well railing.

This is not difficult to do, but Liu Yi did not expect too many ways to improve it. At most, a folding ladder is also made on the well railing. When approaching the city wall, the folding ladder is placed and placed directly on the city wall. The soldiers in the well railing can directly step over the folding ladder and rush up to the city wall to fight against the enemy.

Then there is a hammer to rush to the city. It has a head that can block the rain. The wood that hits the city is stronger. Don’t break the city gate before it breaks open.

After these, there are long-range strike equipment such as catapults and crossbows. The amount is also very large. Liu Bei is now short of soldiers and needs to break the city as soon as possible. These siege weapons must be sufficient to make up for the shortcomings in military strength.

However, the wood needed is not a small number of them. Before Liu Bei's army arrived, the 500 elite troops he brought might have to act as lumberjacks for several days.

...

Time goes forward ten days.

Location: Mianyang.

The fierce shasha did not last long. When the first ray of sunshine in the morning fell on this city, the war was basically over. Wei Yan held the sword with one hand and walked up to the city tower silently. Looking at the quiet city, occasionally, the remaining Hanzhong soldiers were dragged out of the people's homes and executed on the spot.

This surprise attack was considered successful. Although Zhang Lu arranged a lot of defenders here, there were few wars. The soldiers guarding the city were too alert. Wei Yan only realized when he led his men to attack the city wall.

"General, this battle was too easy." The deputy general who followed Wei Yan smiled and looked at Wei Yan. He won a victory. His morale was strong and his confidence was strong, and he felt that the soldiers in Hanzhong were all natives.

"It's not difficult to attack the city, but the difficult thing is to defend the city." Wei Yan held the female wall with his hand and looked at the scene in the distance. From the moment he sent troops, he did not expect that he would fail. It was their business for his opponents to be lazy. He believed that even if he had not been lazy, Wei Yan would not feel that they could block him with the ability shown by the Mianyang defenders. At best, it was just to reduce some casualties for himself.

However, when Mianyang loses, Zhang Lu will feel a headache. It is only seventy miles away from Nanzheng.

"The whole process of the announcement is issued. From now on, the people in the city are not allowed to move without authorization. If you violate the violation, you will take one thousand men and more flags. You will leave the city at night and enter from outside the city during the day. Remember, the momentum is strong, so that Zhang Lu thinks that the main force of our army is here." Wei Yan turned his head and looked at his deputy general and said.

"Here!" The deputy general responded when he heard this, and saw that Wei Yan had no other orders and said goodbye and left.

Touching the female wall, Wei Yan looked at the large plain outside the city wall, with a strong sense of excitement in his eyes. I wonder who Zhang Lu would send to fight. This Hanzhong is my first battle for Wei Yan to make achievements!

Mianyang is only seventy miles away from Nanzheng. Zhang Lu received information about Mianyang's capture almost that night.

"Wei Yan? Who is this?" Zhang Wei asked on the side frowned. He was very unfamiliar with a name that he had never heard of.

"The banner is Liu Bei's banner." The general who came to report shook his head in a daze, saying that he had never heard of this person, but he really recognized Liu Bei's banner.

"Liu Xuande, didn't he leave?" Zhang Lu slapped the table and snorted angrily.

"I'm afraid it's a fraud!" Yan Pu, who was standing beside him, said with a wry smile. The result he didn't want to see finally happened, and he didn't expect that the other party actually chose Mianyang to attack!

"Shijun." After thinking for a while, Yan Pu looked at Zhang Lu and said, "It is difficult for the army to march in the Mianyang area. Wei Yan should be just a side division in a brigade. He can send a general to lead the army to pacify. I am worried that Liu Bei still has plans!"

Liu Bei could not attack for no reason. Since Mianyang was invaded, there must be a later move, so it is not advisable to act rashly at this time.

"Who can go to pacify Mianyang?" Zhang Lu nodded and asked after hearing this.

"I'm willing to go!" Zhang Wei took a step forward and bowed to Zhang Lu.

"Shijun, why use a cattle knife to kill a chicken?" Another person under the tent stood up and bowed to Zhang Lu and said, "This little thief only needs to give the last general a team of men and he can wipe them out in less than ten days!"

Everyone looked at it, but it was Yang Bai.

Seeing this, Yang Song frowned and said, "Nonsai, Liu Bei's command is all powerful and brave. Although this person has no reputation, since he dares to attack Mianyang, how can he be an easy person?"

Yang Bai is Yang Song's brother, and his ability is not necessarily good, but first of all, he has a good background, and secondly, with Yang Song's secret response, he has become a general under Zhang Lu. However, he is not aware of himself. Yang Song is clear about how much he has, his brother.

Zhang Weiping was always incompatible with Yang Song, but when he saw this, he sneered: "Since General Yang has this intention, the other party is just an unknown person, so why should he stop it? If Bo Nian (Yang Song's name is uneasy), I can lead my army to siege Zhongqi. How about protecting him?"

"No need!" Yang Bai snorted coldly when he heard this, and said to Zhang Lu: "Mr. Shi, if you cannot defeat the enemy, I will be willing to apologize for death!"

"It's so serious." Zhang Lu waved his hand and said, "It's convenient for you to get eight thousand troops, and you must expel the thief army."

"The last general will take the order!" Yang Bai took the order, looked at Zhang Wei with a sneer, took the order arrow, turned around and left.
