Chapter 232: Interdependence

Liu Beijun's camp, now Liu Bei's Chinese army has reached halfway, and the former army can reach Nanzheng in about two or three days.
"Princess, what was Bo Yuan's letter at this time? But where did he reveal his whereabouts?" Pang Tong came in and asked Liu Bei when he was frowning.
"It was exposed ~" Liu Bei sighed and handed the letterhead to Pang Tong said: "Wen Chang had captured Mianyang half a month ago and successfully attracted the main force of Hanzhong. Unfortunately, I failed to arrive in time, Bo Yuan saved the text Chang, who fraudulently claimed 5,000 people with 500 people, and forced Zhang Lu, who was under the banner of Yunchang, had to withdraw his troops. However, it was difficult for me to wait to break Hanzhong. "
"If Hanzhong's main support is back, he will soon be able to find out Bo Yuan's truth and reality, but he can order the former army to speed up and converge with Bo Yuan first." Pang Tong has some toothache, he remembers that the road is not easy to go, ahead of schedule Arrived in ten days, what did Wei Yan run so fast?
Liu Bei nodded, Wei Yan ’s intention to strike east and west was a failure. Now Liu Yi ’s big camp ca n’t be lost, otherwise Liu Yi will retreat, Zhang Lu will take advantage of the situation, and the road on this side is broken, then their trip is considered to be White ran away.
Seeing the last, Pang Tong suddenly smiled and said, "Princess, Bo Yuan, please ask Zhang Lu for some soldiers, horses and food."
"Thirty horses and horses, how can Ji Yu be willing to give them?" Liu Yi heard and shook his head with a wry smile. Since entering Shuzhong, Liu Bei has successively received more than 10,000 soldiers from Liu Zhang. Although Yizhou is rich in nations but rich in people, Yizhou It is impossible for Liu Zhang to agree to the law.
"Just ask him not to give it." Pang Tong smiled: "Otherwise, why wait for our army to lay Hanzhong, why is there a shot at Liu Zhang? I waited for him to bathe the blood in Yizhou, but Liu Zhang detained me from the rear for various reasons. People, let General Wei almost kill his opponent, is this reason enough? "
Liu Bei didn't think about it in the first place. Now Pang reunite, and understand that Liu Yi is not a joke, but he really wants to ask for it, and he didn't prepare for Liu Zhang to give it, just to make an excuse to send troops to Yizhou.
I forgot about it.
However, Liu Bei did not answer. This kind of thing was still not in line with his image. He was going to write to Liu Zhang in a while. He would first ask for 50,000 Ukrainian people, and then give tens of thousands of stone grains and grass. Wan, Liu Yi told him before that he wanted the road from Shutong Shuzhong to Hanzhong. He started construction after he settled Hanzhong. He was still considering it before. Now Liu Bei does n’t think about it. After all, Hanzhong is his own territory. The benefits are not harmful.
Think about what else you can ask for?
"Princess?" Pang Tong couldn't help but shook his hands before watching Liu Bei meditating there.
"What's the matter with Shi Yuan?" Liu Bei returned to his mind, and subconsciously wiped the corner of his mouth, asking.
"I want to discuss the attack on Nanzheng with the protagonist." Pang Tong laughed.
...
Since Zhang Lu did not choose to surrender or retreat, Liu Yi should prepare for the next siege.
With a few craftsmen, Liu Yi started to calculate the defense of Nan Zhengcheng across the distance. Huang Zhong and Guan Ping, who were responsible for protecting Liu Yi, only saw Liu Yi holding a tripod, measuring something, and soon a group was reported. Data, and then let the artisans around me record, Liu Yi reported numbers, but it fell on the paper. The artisans wrote a lot of 123456 symbols, which made people dizzy.
Guan Ping looked at the tripod in Liu Yi's hands somewhat curiously and asked, "Sir, what is this?"
"It is used to measure the city height." Liu Yi simply replied.
"This thing can be measured?" Guan Ping did not channel.
"Yes, you can know the distance from the city, but now you can only have a rough estimate." Liu Yi laughed. In fact, it is a geometric problem of a right triangle with one side and angle and then another right side. It ’s not very advanced, but people who do n’t study mathematics in general are really not easy to understand. Liu Yi is a rough concept and can understand the best. It will be useful in the future. If he does n’t, he wo n’t Go to teach specifically, and wait for yourself to publish a book later, buy it and read it.
"But sir, the people on the city wall seem to be looking at us." Guan Ping glanced at the Hanzhong soldiers closely watching the city wall with some concern. If the other party sent troops at this time, it was very embarrassing.
"It's okay. When we put down the suspension bridge and open the city gate, we ran early." Liu Yi smiled indifferently, and then looked at the craftsmen: "Is the data remembered?"
"Already remembered." Several artisans nodded one after another.
"Okay, change the side!" Liu Yi turned his horse and said to Guan Ping and Huang Zhong: "Let's go to Ximen."
Huang Zhong and Guan Ping were a little speechless, even if they did not fight for the time being, but it was so majestic that they ran to the bottom of the city to calculate the data, is it really good?
On the city wall, Yang Ren, who had returned, frowned at this pedestrian: "What are they doing?"
Several generals shook their heads, God knows.
"Look at them, close to the city wall, and shoot immediately!" Yang Ren always felt that this group of people had problems, but they didn't know what they were doing, so they could only warn the soldiers.
After spending more than an hour, Liu Yi ran around Nanzheng and collected all the data he needed. The next step was to build a sand table and design engineering equipment. The soldiers were constantly cutting down timber for use.
"The height of Nanzheng's walls is basically between five feet and two feet and five feet and four feet. Our army's catapults have an effective range of two hundred steps, which is usually calculated, and their height is blocked ..." Che, Jing, and Ladder are all the main siege weapons after the war. Liu Yi has made various improvements.
The siege equipment of this era basically has room for improvement, especially the catapult. The existing catapult has not selected the best point on the problem of the arm. The range is naturally close, regardless of the attribute bonus. As far as the change of the force arm is concerned, the new catapult designed by Liu Yi is much stronger than before, not to mention the attribute bonus. In the battlefield of this era, it is definitely an enemy's nightmare!
"Follow this drawing!" Liu Yi recruited the craftsmen and handed them the new catapult and ladder designed by him, and let them do it themselves. Jing Yi Liu Yi still wanted to improve and improve it, but it has not been designed yet.
"Sir, this catapult is no different than before." Guan Ping had been watching around him, and after seeing the craftsman go, he couldn't help but wonder.
"The change of the force arm is enough to exert a stronger effect." Liu Yi smiled.
"What?" Guan Ping looked at Liu Yi blankly.
"I'll make two models for you." Liu Yi had no choice but to find some waste wood. The carving knife naturally slipped out of the sleeve, and he carved out the waste wood.
Watching each component take shape in Liu Yi's hands, even if I have seen it many times before, but every time I see it, it still gives Guan Ping a dazzling feeling.
After a while, the two catapult models were ready.
"This ..." Guan Ping looked at Liu Yi with some doubt: "What's the difference?"
Except for the wooden poles that the catapults throw at the rocks seem to be a little different, the other aspects are basically the same.
"Look!" Liu Yi pointed to one of them: "This is the previous one."
Randomly picked up a stone from the ground and hit it with a trigger. The stone shot a distance of about three feet. Liu Yi made a mark on the ground, then picked up the stone and mounted it on another catapult model. Follow suit.
Three feet six!
Guan Ping looked at the two catapults that were not too far apart, but the range was so different? If this is true, I am afraid there are fifty or sixty steps!
"This is the gap!" Liu Yi looked at Guan Ping and smiled. If it weren't for the gap, he wouldn't bother to design.
Guan Ping nodded: "If it is so powerful, if there are thirty such catapults, why don't you worry that Nan Zheng will not break?"
"You have to cooperate with the cloud ladder, Jing 欗, and Chongcheng car." Liu Yi fumbled his chin.
After all, catapults have a greater deterrent effect on the battlefield than their actual lethality.
"Sir!" Huang Zhong came across the curtain and came to Liu Yi, arching his hand: "General Wei sent someone to send the letter."
"Oh?" Liu Yi heard the letter from Huang Zhong, and the smile on his face gradually disappeared.
"Sir, what happened?" Guan Ping wondered.
"Wei Yan's soldiers can't move for the time being." Liu Yi handed the script to Huang Zhong and sighed.
He did not expect that the battle of Mianyang was so tragic that the army brought by Wei Yan could not be fought, but the elite division brought by Jingzhou!
Breaking Yang Bai first and damaging hundreds, and then a few days offensive and defensive battle with Yang Ren, Wei Yanyu's soldiers and horses were constantly consumed in battles, and today, there are only less than 300 people left. Army, Liu Yi had people tell Wei Yan to attack Yangpingguan by some strongmen ~ EbookFREE.me ~ After reading the book, Huang Zhong sighed silently. Three thousand people hit the remaining three hundred people, even if it was The battle of defending the city, and the losses added up for a few days in a row, can not collapse. Except for all Jingzhou soldiers, Wei Yan can do this. It is very rare. Even without personal participation, you can imagine that battle. Tragic.
This time it was Pang Tong ’s calculation error. Of course, there were also reasons for Wei Yanli ’s eagerness to be too rushed. In short, he failed to achieve the strategic goal in advance, but Sai Weng lost his wits. In the DPRK, things in Hanzhong also had a period of time to receive news. This time just gave Liu Bei the opportunity to seize Hanzhong, and at the same time, he could continue to demand money and food from Liu Zhang to strengthen himself by attacking Hanzhong.
"People are fine, just send someone a letter to Wen Chang for me, and send someone to urge the hero." Liu Yi sat down and said.
In such a large camp, there are actually only 500 people. Zhang Lu can find out if he sends someone to try it out. Liu Yi seems calm and even dares to run around under the city. In fact, he has always lacked a sense of security. Zhang Lu couldn't think of sending someone to try again.
Fortunately, Huang Zhong played well the other day, scaring Zhang Wei and calming Zhang Lu.
