Ten days of road, in order to leave enough barracks for the later army, Liu Yi walked for thirty days, at this time, Liu Bei's main army was almost halfway there.

After splashing a handful of water on his face, Liu Yi looked around, it was still the feeling of being surrounded by mountains, but it was only separated by a mountain from the Hanzhong Plain.

"Sir, over this mountain, it is the Hanzhong Plain, and it is only thirty miles away from Nanzheng." Guan Ping came to Liu Yi's side with a knife and took a breath, the weather was getting hotter, and there was a stuffiness in the air in this Hanzhong area, which made people very uncomfortable.

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

"I asked the guide, I can't go, I have to walk a little way." Guan Ping shook his head: "Maybe it's slower than taking the land route." ”

"No matter, the war is your business, and the siege equipment has to be transported, and it must be transported by water, and a hundred soldiers will be assigned to set up camps, you lead the team, just make it simple, the most important thing is to prepare enough wood, air dry, after we have converged the army of the lord, and then go to Nanzheng, Wenchang's side, it should be almost done, send a few people to the vicinity of Nanzheng to find out if there is a large army to support Chuyang recently, by the way, look at Nanzheng Xushi, this battle, it is best to fight down, break through Nanzheng, anything is easy to say, it can't be broken, It's not going to be a good fight, remember, be smart. ”

"Whoa!" Guan Ping agreed, turned around to arrange, Liu Yi began to take some man-made vehicles to transport things, after attacking the Hanzhong Plain, the grain and grass were sent directly to the front line from Jiameng Pass, this road is considered invalid, but the current problem is whether the military food they carry can support the first batch of grain and grass to be transported here, although the road and meeting place for the grain and grass have been set in advance, and Liu Feng personally escorted the grain and grass, but there will always be an error, Liu Yi is a little uneasy, and asked Huang Zhong to send someone to meet Liu Feng, Don't make mistakes, at least not too much.

Logging and then building a few transport ships is not a difficult task for Liu Yi today, and the next attack on Nanzheng is the main event.

Liu Yi thought about it, first of all, Wei Yan's side had to be able to successfully sneak attack and occupy Canyang, and then Zhang Lu had to raise troops to attack Canyang as soon as possible, and transfer some of the soldiers and horses in the Nanzheng area, all of which were impossible, Zhang Lu was not so stupid, and then, depending on the speed of the attack here, Liu Yi now considered other siege equipment in addition to shipbuilding.

Siege equipment, the main thing is not catapults, bows and arrows, the most important thing is the ladder, the so-called ladder is not the kind of simple ladder on TV in the previous life, the defenders of the city took something to the top and knocked it down, in fact, as early as the Spring and Autumn Period and the Warring States Period, the public loss class has invented the ladder, there are wheels at the bottom, which can be moved, so it is also called a ladder car, the ladder can swing up and down by manpower, and one end of the ladder is equipped with a barb, once the city wall is hooked, it is difficult for the soldiers in the city to push the ladder away.

There is no shortage of drawings for ladder trucks, Liu Yi has already begun to study them when he was in Jingzhou, and he has also tried to make a few.

It doesn't matter how high or low the attributes are, but most of the attributes that appear are stable, sturdy, etc., and occasionally there will be some attributes that increase courage, but they are rare.

But one, the ladder is a bit of an eyesore, different from the fire trucks of later generations, the ladder body at this time is one, it is not very convenient to carry, Liu Yi imitated the way of the fire truck, the ladder body was changed to a combination of two ends, equipped with a winch in the middle, half of the ladder body is fixed, and half can be adjusted up and down through ropes and pulleys, and there is no need to carry up and down the adjustment by manpower.

In addition, there is a change on the chassis, the inside can hide people, and the body also has a protective baffle, which can protect the soldiers in the car from injury in the process of arrival, and there are fixtures on the chassis, once they 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 is designed by Liu Yi according to the structure of the fire truck, but there is no way to follow the ladder, the friction between the wood is too large, it is difficult to slide freely like the fire ladder, and the main ladder is fixed, and the auxiliary ladder should be adjusted according to the different height of the city wall, and it cannot be like the fire truck, so Liu Yi is designed with a bearing connection and a folding structure, which can save the time of the ladder to the greatest extent.

Liu Yi has not yet had accurate data on the scale of Nanzheng, but with Liu Bei's troops, it is rare to besiege a county city, so Liu Yi is ready to design a ladder according to the budget of a city wall storm, such a ladder car must have twenty, at least so many, and then cooperate with the well railing, which is similar to a mobile bucket, people stand on it, basically the same as the city wall or even slightly higher, and the archers launch an attack on the defenders on the city wall through the well railing.

This is not difficult to do, Liu Yi didn't think of too many ways to improve, at most he made a folding ladder on the well railing, when he was close to the city wall, the folding ladder was put down and directly put on the city wall, and the soldiers in the well rail could directly step on the folding ladder and rush up to the city wall to fight the enemy.

Then there is the ram of the city, which has a roof to block the rain of arrows, and the wood that hits the city is stronger, and the gate of the city is not opened, and it is broken first.

After these, it is the catapult, bed crossbow and other long-range strike equipment, the amount required is also a lot, Liu Bei now has few soldiers, and he has to break the city as soon as possible, these siege weapons must be enough to make up for the lack of troops.

However, there is not a small amount of timber needed, and before Liu Bei's army arrives, the five hundred elites he brought will probably have to serve as loggers for a few days.

……

Ten days later.

Location: Chuyang.

The fierce fighting did not last long, when the first rays of sunlight in the morning fell on this city, the war was basically over, Wei Yan held his sword in one hand, silently walked up to the city tower, looking at the silent city, occasionally there would be remnants of Hanzhong soldiers were dragged out of the people's homes and executed on the spot.

This surprise attack was considered a success, although Weiyang was also arranged by Zhang Lu to have a lot of defenders, but there were few battles here, and the vigilance of the soldiers defending the city was too low, and Wei Yan only reacted when he led his men and horses to attack the city wall.

"General, this battle is too easy to win." The deputy general who followed Wei Yan looked at Wei Yan with a smile, he had won a battle, his morale was strong, and he had a lot of confidence in speaking, which was quite a bit like the generals and soldiers of Hanzhong were all chickens and dogs.

"It's not difficult to siege a city, it's hard to defend it." Wei Yan held the female wall with his hand, looking at the scene in the distance, from the moment he sent out the troops, he didn't expect to fail, the opponent's slackness was their thing, he believed that even if he didn't slack off, with the ability shown by these defenders in Weiyang, Wei Yan didn't feel that they could block him, at best, it was just to reduce some casualties for himself.

However, if you lose it, Zhang Lu will have a headache when you think about it, and it is only seventy miles away from Nanzheng.

"Spread my military order, proclamation of the whole process, from now on, the people in the city are not allowed to move around without authorization, violators are beheaded, you bring a thousand men and horses, bring more flags, go out of the city at night, and enter from outside the city during the day, remember, the momentum should be loud, so that Zhang Lu thinks that the main force of our army is here." Wei Yan turned his head and looked at his lieutenant.

"Whoa!" When the adjutant general heard this, he answered, and seeing that Wei Yan had no other instructions, he took his leave and left.

Touching the female wall, Wei Yan looked at the large plain outside the city wall, with a strong excitement in his eyes, I don't know who Zhang Lu will send to fight, this Hanzhong is the first battle of my Wei Yan's achievements!

It was only seventy miles away from Nanzheng, and Zhang Lu received information that it had been captured almost that night.

"Wei Yan? Who is this? Zhang Wei on the side frowned and asked, a very unfamiliar name, I have never heard of it.

"The banner is Liu Bei's." The general who came to report shook his head blankly, saying that he had not heard of this person, but he did recognize Liu Bei's banner.

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

"I'm afraid it's a fraud!" Yan Pu on the side smiled bitterly, the last thing he wanted to see happened in the end, and he didn't expect the other party to choose Chuyang to attack!

"Master." After thinking about it, Yan Pu looked at Zhang Lu and said: "In the area of Chuyang, it is difficult for the army to march, then Wei Yan should only be a brigade of partial divisions, and a general can be sent to lead the army to pacify, I am worried that Liu Bei still has a plan!" ”

It is impossible for Liu Bei to attack for no reason, since the fall of Chuyang, there must be a back-up move, and it is not appropriate to act rashly at this time.

"Who can go to pacify Chuyang?" Hearing this, Zhang Lu nodded and asked.

"Little brother is willing to go!" Zhang Wei stepped forward and bowed to Zhang Lu.

"Shijun, use a knife to kill chickens?" Another person under the tent stood up, bowed to Zhang Lu and said, "Such a thief, you only need to give the last general a horse, and you can exterminate it in less than ten days!" ”

Everyone looked at it, but it was Yang Bai.

Seeing this, Yang Song on the side frowned and said: "Nonsense, then Liu Bei's subordinates are all strong and brave people, although this person has no reputation, but since he dares to attack Weiyang, is it easy?" ”

That Yang Bai is Yang Song's younger brother, and his ability is not necessarily good, but first, he has a good background, and secondly, Yang Song secretly takes care of him, and he has also become a general under Zhang Lu, but he has no self-knowledge, Yang Song is clear about how many catties and taels his brother has.

Zhang Weiping and Yang Song were not on good terms, but when they saw this, they sneered: "Since General Yang has this intention, the other party is just a nobody, so why obstruct it?" If Bonian (Yang Songzi) is not at ease, I can lead the army to plunder the formation for Zhong Qian, how about protecting him? ”

"Not necessarily!" When Yang Bai heard this, he snorted coldly, and saluted Zhang Lu: "Master, if you can't break the enemy, the last general is willing to apologize with death!" ”

"That's a big deal." Zhang Lu waved his hand and said, "It is convenient for you to have 8,000 men and horses, and you must expel the thief army." ”

"The last general commands!" Yang Bai took the order, glanced at Zhang Wei with a sneer, took the arrow, and turned to leave.
