In the direction of Jiankang, with a relatively small amount of land and a small number of people, it was able to hold half of the south of the Yangtze River, mainly relying on the Huai River defense line. And the Huai River defense line, Shouchun and Zhongli, is one of the two most critical points.

Most of Liu Yu's army is still in Shandong, and the newly occupied territory also needs to be consolidated, so a large number of troops must be left, otherwise, the recovered territory will be lost and lost, so it is better not to mobilize the people to recover.

However, Fu Rui's army is on the front line of eastern Henan, which poses a threat to Zhongli and Shouchun, once these two cities are lost, I am afraid that the Huai River line will be controlled by Fu Rui's army, after all, this is an elite army with 100,000 people.

Liu Yiru still doesn't know that now that Zhongli has been lost, Liu Yu himself is struggling to support himself in Shouchun City, but even from a perspective of thousands of miles away, the situation is not optimistic.

The problem is also that everyone knows that the Jin State is actually supported by several forces, the Beifu Army is a self-contained system, and the Jingzhou Army is now able to cooperate because Huan Chong and others chose to make peace with Xie An, but other armies, whether it is combat effectiveness or reliability, can not help Liu Yu at all.

Obviously, Fu Rui also saw the situation, and when Liu Yu's situation was at its most dangerous, he struck a thunderous blow.

Duan Ye actually did a lot of things that were not conducive to Liu Yu, but now, where is the time to speak out? Especially how can you talk to Liu Yiru about this. Liu Yiru is very worried, this is human nature, but in fact, from Duan Ye's point of view, Fu Rui can definitely cause a lot of trouble to Liu Yu, but if he wants to bring danger to Liu Yu, it is almost impossible.

After thinking about it, Duan Ye still said: "Sister Ru, don't worry, Jiren has his own natural appearance, Brother Liu will definitely be fine." ”

"Hmm." Liu Yiru nodded lightly, in fact, now she also knows that it is useless to think too much, even if Duan Ye is willing to help her, it is beyond the reach of the whip.

She can only pray silently for her brother in the dead of night.

At the same time, Li Fei also said slowly: "...... If Guanzhong has a high-rise position in the Central Plains, then Longxi has a high-rise position in Guanzhong. In fact, Longxi is not only the upstream of Guanzhong, it also has the upstream trend of Hanzhong and Sichuan. Childe, you see, Weishui, Bailongjiang, Xihanshui and other rivers all originate in Longxi. Among them, the Weishui that nourishes the Qinchuan River flows eastward through Guanzhong, while the Bailongjiang River flows south through Yizhou, and the Western Han River flows eastward through Hanzhong. In terms of topography, the topography of Longxi is significantly higher than that of Guanzhong, Hanzhong and Sichuan, so starting from Yanhuang, in all wars, it is more difficult to attack Longxi from Guanzhong, Hanzhong and Sichuan, but it is easier to attack from Longxi. ”

Seeing that Lu Hong listened carefully, and did not have the kind of indifferent appearance when he was fighting with Duan Ye, Li Fei was also relieved, fortunately, these three sons are still very smart in nature, but they only deliberately pretend to be stupid occasionally.

Lu Hong can't help it, Lu Shao and Lu Su are both too good, he is not like this, there is really no room at all. If he seemed to be very capable, smart, and capable at that time, then I am afraid that there would be no benefit except for exposing his death in advance.

Taoguang is a method that has been proven to be effective for hundreds of years and thousands of years. The so-called shot shot at the first bird, Lu Shao and Lu Su both appeared, looking aggressive, but what their status in Lu Guang's heart is, I'm afraid it remains to be discussed.

Li Fei also saw this clearly, so he resolutely chose to follow Lu Hong in a low-key manner, because he believed that compared to Lu Su or Lu Shao, Lu Hong was a more trustworthy and promising person.

"Third son, let's continue." Li Fei said.

"Yes, sir, please." Lu Hong's attitude was extremely respectful.

"Third son, the reason why our Liangzhou is important is because for Guanzhong, Hanzhong and Shuzhong, no matter which side can obtain Longxi, it will have achieved a geographically advantageous situation. Think about it, why didn't Zhuge Kongming use Wei Yan's Meridian Valley scheme? ”

Sitting and discussing, it is natural to ask questions and have big questions, Li Fei is actually to Lu Hong now, to a certain extent, it is almost a teacher-student relationship. Now, Li Fei is focusing on cultivating Lu Hong, especially cultivating his strategic vision and way of thinking. This time, he also wants to accept the results of these days by the way.

The so-called Meridian Valley conspiracy refers to the Three Kingdoms period, when Zhuge Liang first went on the Northern Expedition, the general Wei Yan proposed a surprise attack on the Meridian Valley, Wei Yan proposed that he could lead five thousand elite soldiers, straight out of the praise, follow the Qinling Mountains to the east, when the meridian to the north, take the nearest road, and quickly reach the city of Chang'an, the defender of the city is the Wei State of the horse Xiahou Nan, this person is cowardly and incompetent, once he hears that the army is coming, once he will escape by boat, so he can take Chang'an in one fell swoop.

After that, Zhuge Liang led the army from the valley to the west of Chang'an to support. Then Wei Yan of Chang'an and the main force of Zhuge Liang surrounded and annihilated the main force of the Wei army in the pass.

However, Zhuge Liang thought that this plan was too dangerous and difficult to succeed, so he abandoned it. After that, Wei Jun also realized this problem and took precautions against the direction of Meridian Valley, and there were no more conditions.

It was because of this incident that Wei Yan felt that Zhuge Liang was too cautious and had no courage, and then he deviated from morality and was unwilling to obey. Later generations also used this as one of the reasons for Wei Yan's rebellion.

This problem is a big problem, the Meridian Valley conspiracy, the core is actually a weak country chooses to take the initiative to attack the core city of a strong country, to be honest, it takes courage and imagination. How to think about it is a very training ability.

Lu Hong thought about it, but still said: "Sir, Lu Hong thinks that Zhuge Liang did not use this plan, not because he was timid, but because Zhuge Liang did not plan to attack Chang'an at all, and his goal should be Liangzhou." ”

Li Fei was quite appreciative in his heart, but he still remained silent and said, "Go on." ”

"Sir, just like you just said, Longxi is in the west of Guanzhong, and Hexi is in the west of Longxi. Therefore, Longxi is enough to control Guanzhong, and Hexi is enough to control Longxi. If you want to map Longxi in Guanzhong, you can connect Hexi, take advantage of Hexi's geographical advantages in Longxi, and attack Longxi after controlling Longxi. Liu Xiuzhi's marriage with Dou Rong is exactly like this, because we are in Liangzhou, which is too important. ”

It turned out that in the early years of the Eastern Han Dynasty, in addition to Liu Xiu's Han Ting, there were three main forces competing for the world: Kui Huan in Longxi, Dou Rong in Hexi and Gongsun Shu in Yizhou. Kui Huan is superficially arrogant, and he is actually plotting to divide one side.

Dou Rong's family has been in Hexi for many years and knows its customs and customs. After Dou Rong occupied Liangzhou, he married Xiongjie, Huaiji Qiang, and won the hearts of the people, and the refugees from the east were endless, and they were pushed by the counties of Hexi, and possessed Jincheng, Wuwei, Zhangye, and Jiuquan. Five counties of Dunhuang.

And Gongsun Shu took advantage of the danger of Yizhou's terrain and made his own decisions in the Yizhou imperial system. And also thinking about dividing the army into two routes, all the way from Jingzhou to the north, all the way from Hanzhong to the north, the two armies, and take the Central Plains, in fact, this is quite similar to Zhuge Liang's Longzhong. It can even be said that Zhuge Liang also borrowed from Gongsun Shu's ideas to a large extent.

But then again, the situation in the world at that time was actually very similar to today. The Jin State occupied the eastern part of Jianghuai Mountain, and the new victory in the river was strong. Although the Murong family occupies Hebei, Murong Chong and Murong Chui have not yet decided the winner, and they are still in internal conflict. Fu Jian was seriously ill, and Fu Hong of Bingguo could only barely keep the core area of Guanzhong. Lu Guang occupied Liangzhou and waited to move.

Lu Hong thought for a while and said, "Sir, when Liu Xiu was concentrating on dealing with the Kwantung heroes, his strategy for dealing with the West was to use Long to control Shu. In order to contain the hustle and bustle, he turned to Dou Rong in Hexi. At the same time, Kui Huan is also trying to win over Dou Rong. However, in the end, Liu Xiu's envoy was more powerful, and Dou Rong and his subordinates were inclined to Liu Xiu and sent an envoy to Luoyang to try. Liu Xiu came courteously, and persuaded Dou Rong with the spirit of a king who embraces the world. Dou Rong and others were moved by Liu Xiu's bearing, insight and sincerity, so they concentrated on doing things. Liu Xiu granted Dou Rong as the pastor of Liangzhou, Zhuanzhi Hexi. After Liu Xiu settled the Central Plains, he raised troops to the west. Dou Rong led the five counties of Hexi to defend the Taishou, vigorously fought the horses, and Yaobing on the river, putting a lot of pressure on Kui Huan; Later, he personally led tens of thousands of foot cavalry, joined forces with Liu Xiu in Gaoping, and joined forces to attack Kui. Kui Huan was destitute and had no plan, took refuge in Gongsun Shu, and was soon defeated. It can be seen that Dou Rong's choice, as Liu Xiu said, is really pivotal, and in a sense, it is Liangzhou that determines the trend of the world. ”

"yes." Li Fei sighed, "When the generals of the Eastern Han Dynasty first attacked Longxi, Wang Yuan, the general of the Kui Huan Department, was based in Longdi and cut down trees and blocked the road. The generals attacked Longdi on their backs, and returned in defeat, so they had to change to the defensive. This shows that Longxi has the advantage of geography over Guanzhong. This is also the reason why Liu Xiu is devoted to getting married to Dou Rong, if there is no way, I don't think Liu Xiu will offer such generous conditions. Dou Rong embraced Hexi and returned to the Han Dynasty, thus changing the strategic situation of the Eastern Han Dynasty in the face of Longxi. So the third son, you have to think more about this. Lu Hong nodded and said: "I think, Liu Xiu's correct strategy must have also inspired Zhuge Liang a lot, Zhuge this person, use troops carefully, take Liangzhou first, you can get the geographical advantage of Guanzhong, this is too important, otherwise, relying on the land of Shuzhong, it is too difficult to take the world." ”

Li Fei smiled and said suddenly: "The third prince thinks that if Zhuge Liang doesn't consider this and instead supports the Meridian Valley conspiracy, do you think it can succeed?" ”

Lu Hong thought for a moment and said firmly: "Can't! ”

"Why?"

Lu Hong said confidently: "Sir, Wei Yan's idea is bold, and if it succeeds, the results are indeed tempting, but in order for Wei Yan's plan to be realized, five conditions must be met at the same time. ”

"Which five?"

"First, Wei Yan led the army from Baozhong, followed the Qinling Mountains eastward into the Meridian Valley, and followed the Meridian Valley to Chang'an, and it took 10 days to complete this trip; Second, Xiahou Nan, the commander of Cao Wei's Chang'an, had to abandon the city and flee when he learned of the sudden arrival of Wei Yanjun. Rather than holding on to the city. Third, when Xiahou Nan fled, he had to leave behind a large amount of grain and grass for the Shu army to eat. Fourth, Wei reinforcements had to wait 20 days before they arrived in Chang'an. Fifth, Zhuge Liang's army set out from Xiegu and must arrive in Chang'an within 20 days to reinforce Wei Yan. At the same time, it was necessary to clean up the other Wei troops west of Chang'an by the way. However, in my opinion, it is unlikely that each of these five necessary conditions will be realized. ”

Li Fei didn't expect that Lu Hong would have such insight, and he also said five reasons for such a clear organization at once, which is rare, and he hurriedly encouraged Lu Hong to continue.

Lu Hong has also entered the state now, and said with a somewhat excited expression: "Let's talk about the first one first." It is rare to cross the Meridian Valley and reach Chang'an within 10 days, from our map, we can know that the Meridian Valley Road is about 600 miles long, the high mountains on both sides face each other, and the water flow in the middle is turbulent, all relying on the plank road on the cliff to pass. If there are bad sectors in between. It must be stopped and repaired before it can continue to pass. If there are many bad roads, the repair time will be very long, and the time to reach Chang'an will be delayed, if it cannot reach Chang'an within 10 days, then the Wei army's meticulous work may get information and be prepared, so that the Shu army will lose the effect of the surprise attack. And two years later, Cao Zhen, the governor of the Wei army, walked from the Meridian Road. That time, Cao Zhen only walked half of the Meridian Valley in a month, which shows that it is not easy to walk the Meridian Valley in 10 days. ”

"That's the truth, Meridian Valley, I've been there specifically."

"Let's talk about the second one. It is a fact that Xiahou Nan, the defender of the Wei army, was cowardly and unplanned, but would he be so afraid that he would really escape by boat as soon as he heard that Wei Yan's army was coming? I'm afraid Wei Yan is too wishful thinking at this point. What if he didn't abandon the city and flee, but held on to the city and waited for reinforcements to arrive? Even if Xiahou Nan really abandoned the city and fled, there would still be Cao Wei Yongzhou assassin Guo Huai! In the past, the battle of Dingjun Mountain, Huang Zhongzhen beheaded Xiahou Yuan, it was this Guo Huai who stabilized the situation and prevented the further northward dredging, and now this brave and scheming Guo Huai has become the history of Yongzhou Thorn, guarding Chang'an together, can he let go of Chang'an and escape with Xiahou Nan? ”

Lu Hong took a breath and said, "Let's talk about the third point." Even if Wei Yan succeeded in occupying Chang'an, how could he guarantee that the Cao army would definitely leave a large amount of grain and grass for the Shu army? If the Cao army carried away the grain or simply burned it, would the Shu army be able to defend the city on an empty stomach? If you want to go to the Meridian Valley, basically, you can't bring too much food, you have to rely on the food of the Wei army in Chang'an to supply, if the army has no food, it won't last a few days. As for the fourth point. Who can guarantee that the Kwantung reinforcements will definitely arrive in Chang'an in 20 days. Not to mention, take Sima Yi's attack on Meng Da as an example, Meng Da estimated that Sima Yi would not be able to reach Shangyong in a month, but Sima Yi arrived in just eight days, killing Meng Da by surprise. Moreover, from Kanto to Guanzhong, there is no natural barrier along the way, which is conducive to Cao Wei's iron cavalry galloping day and night. ”

Li Fei saw that the more Lu Hong spoke, the more energetic he became, the more confident he became, and he was very happy in his heart, you know, Lu Hong is the student he taught, the student is out, and he is also happy to be a teacher.

Lu Hong took a deep breath and said: "As for the fifth point, the Shu Road is already difficult to walk, Zhuge Liang led the army from the Xiegu Valley to Chang'an, and he has to travel thousands of miles on the plank road, how can he guarantee that he will be able to reach Chang'an before the arrival of Cao Wei's reinforcements?" In case it fell behind the Cao army, Wei Yan's army was eaten by the Cao army, not to mention, Zhuge Liang's Northern Expedition army would be stationed under the fortified city and fall into a dilemma. After Lu Xun burned the company camp, the elite of the Shu army was almost lost, Zhuge Liang worked hard to manage this force for nearly 10 years, if it fails again, Shu is afraid that it will soon be destroyed! If any of these five points goes wrong, the Meridian Valley conspiracy will definitely fail, not to mention that these five may have problems? Therefore, I think that this Meridian Valley conspiracy is not feasible at all. ”

After Lu Hong said so much in one breath, his mouth was a little thirsty, and he hurriedly grabbed the water cup to drink water, while Li Fei clapped his hands lightly. Because Lu Hong's exposition is really wonderful.

Li Fei naturally praised again and again, and Lu Hong was also humble again and again, and after a few rounds of concessions between the two sides, Li Fei said meaningfully: "Liangzhou is now in the hands of Lord Thorn Shi, that is the blessing of God!" Third son, you must seize the opportunity. ”

Lu Hong knew that Li Fei's true meaning was of course beyond words, but in fact, he was persuading himself to join the battle of the two elder brothers. Because of all the concerns in the past, for a long time, Lu Hong basically adopted an evasive attitude towards this issue, he knew Li Fei's intentions very well, and he was also grateful that Li Fei was willing to burn his own cold stove, instead of burning the hot stove of his two brothers. However, all along, Lu Hong has always been entangled in family affection. He did not want to turn against his father and brother, nor did he want to get involved in a naked power struggle. More importantly, in such a place as Liangzhou, he believes that whether it is Lu Su or Lu Shao, their abilities are far beyond the limits of Liangzhou, and there is basically no difficulty in doing a good job in Liangzhou.

Li Fei took the opportunity to say at this time: "Third son, we talked so much just now, didn't you notice?" Liangzhou is such an important place, how can it fall into the hands of others? Childe, if you have Liangzhou, not only to protect yourself and take care of the people, but more importantly, the world has not been peaceful for almost 100 years, and now people are at peace, it is the time for Mingjun to be born and ascend to the heights! If Gongzi can take Liangzhou, think that he is the foundation, and slowly run Hexi Longyou, there is a complete possibility of unifying the world, and if Gongzi does not take the initiative to fight, now the competition between the two sons has entered the white heat, and now it seems that both sides have entered the sandwich road, and it is difficult to turn back, three sons, do you think it is possible for you to continue to stay out of the matter? ”

Li Fei's words woke up Lu Hong all of a sudden. He had to admit that Li Fei was right, if Lu Su and Lu Shao continued to do this, the result would be obvious, they must be separated from life and death, and at that time, he would definitely be forced to choose a side, either a friend or an enemy, and that scene was what Lu Hong was most worried about.
