After the Liaodong Battalion and the Beiping Battalion drove to the Nanpi City, Liu Yi did not immediately start the siege, in addition to improving the preparations before the battle, he was also waiting for the other battalions to arrive at the strategic location and the arrival of the second battalion of Huwei Suzaku, of course, this is only on the surface, the military division meeting of Linxian County has already set the strategy of the war, at this time only need to make some flexible changes according to the actual situation, the real reason is that when he and several military divisions plan the war, there is a stage division, and the strategy of Linxian belongs to the second stage, The focus of the first stage is to press on the whole line of the army, creating a huge momentum of storming the city, and the killer is the Ganning Flying Tiger Army that only went out half a month later.

The first battle of the Tiger Guard Battalion in Anxian County, with the cooperation of the Vermilion Bird Battalion, annihilated the eight thousand defenders under Lu Weihuang, but the siege war has always been a matter of wounding the enemy 1,000 and losing 2,000 self-inflicted wounds, and the Tiger Guard Battalion also paid more than 11,000 casualties for this, after a short period of rest and proper placement of the wounded soldiers, Zhang He led the army straight to Nanpi, and the day of arrival was only less than three days later than Liu Yi.

Hearing that Zhang He came, Liu Yi and several military divisions led the generals to greet them, expressing their appreciation and respect for the soldiers of the second battalion of Huwei Suzaku, although the casualties of the Huwei battalion in Anxian County can be described as a wounded muscle, but the victorious division has been in battle for a long time, and the spirit and fighting spirit of the soldiers made Liu Yi extremely satisfied. But at this time, the morale of the Tiger Guard Battalion is like a rainbow, but it can't be vented!

"General Zhang took Anxian County in three days this time, established the first merit, and respected it in his heart, but the general is not strange, this Nanpi City is still strong above Anxian County, but the depth is much larger, and the defenders in the city are six times larger, and the attack on this city requires the coordination of our battalions." Gao Shun said on the side, and the state of the war, Zhang He was injured in Zhang Liao's gun because of his efforts to stop Lu Bu, but the two did not know each other because of this, at this time the relationship was extremely harmonious, Gao Shun and Zhang Liao are friends with each other, and Zhang He is also quite similar, of course, the last time as the commander-in-chief attacked the tiger prison, he also let Jun Yi see his strength, so he knows a lot about his people, knowing that he is just eager to fight, and the Tiger Guard Battalion has accumulated a lot of experience in attacking Anxian County in addition to high morale.

"Jing Fang and Ziyi came three days earlier with the main army, presumably they have learned about this city in detail, and how to coordinate is to listen to the dispatch of the lord." Gao Shun's words were very polite, Zhang He also knew his ability to attack the city, and when he said this, he knew that Nanpi must be a piercing hand! The sturdiness is still above Anxian, and the attack surface has expanded a lot, so of course Jun Yi understands what this means.

Although Anxian is strong, the width of the city wall can not be compared with Nanpi because of the area occupied, so that the defenders' blow to the besieging side is much larger, and the lethality that can be given is also enhanced, if the Suzaku Battalion has to take out thirty bombardment cannons to deal with Anxian, the number in Nanpi is at least tripled, and as far as he knows, Li Tieniu's Suzaku Battalion has only seventy-eight bombardment cannons, although this thing is a siege weapon, but due to the complexity of manufacturing, the loss is high, and it cannot be taken and demanded, if there is no cover of the bombardment cannon, The casualties of the soldiers will also increase, and if the 50,000 defenders in the city are annihilated like Anxian, I am afraid that the three battalions under the city will also suffer heavy losses.

This truth is not difficult, Zhang Yiyi immediately understood, Liu Yi knew that although as long as the necessary casualties to achieve the strategic goal were unavoidable, but he still wanted to control this number to a minimum, so how to effectively attack Nanpi and reduce casualties has become the biggest problem at the moment, this is by no means that the pre-war preparations are not detailed enough, but the plan can be set at the time of planning, and the actual implementation will be based on the current situation, no matter how good the strategy is, if the army's execution is not enough, it is equal to zero.

While speaking, the blue arrow led a team of soldiers to carry the sand table of Nanpi City in, these days Liu Yi and the generals carefully observed the city and the surrounding terrain, Tian'er will make one by one in the sand table, until today it was completed, the shrunken Xiongcheng on it is very different from reality, the surrounding landform is also very close, at this time the camp of Zhang Hehu Wei Camp and Tie Niu Zhuque Camp was also added.

As soon as everyone saw it, they got up and gathered in front of the sand table, Li Tieniu's face also deepened after a while, the sand table of the Youzhou army will be marked with numbers, and the generals have already learned it in detail, so as soon as he saw this city, he knew that its city walls were at least three times longer than An County, four points higher, and the moat in front of the city was much wider, such a distance and height, the attack range and accuracy of the bombardment cannon would be limited, and if you want to exert the greatest power, the battle line must move forward, and the bed crossbow and catapult on the city are condescending, It can pose a great threat to the Sky Bombardment, and even if he moves out all the equipment of the Suzaku Battalion, he is afraid that it will be difficult to cover the entire attack surface.

"My lord, the enemy army also has catapults and bed crossbows in this battle, although the range power is far less than our army's sophistication, but there is a condescending trend, Nanpi Chengtou is still a few zhang higher than Zhi'an County, with the iron bull to guess that our bombardment cannon wants to exert the maximum power will enter its range, and there will be a loss, as for the details, it needs to be observed on the spot in wartime." Seeing Liu Yi's inquiring gaze, Li Tieniu said cautiously, after dealing with these sophisticated equipment in the Vermilion Bird Camp for a long time, Tie Niu was naturally affected, Liu Yijun's sky-bombing cannon was not a secret as early as when he attacked the Tiger Prison, this kind of siege weapon will naturally be imitated by the princes of all walks of life, and in the battle of armaments, the range, frequency, and destructive power of these numbers are all things that he has to carefully consider before the battle, without full certainty, he will never say anything, and the slightest difference will be a thousand miles.

"Okay, the iron bull can be so fortunate for the Suzaku battalion, the siege battle, the power of the equipment is not the cause of the decisive victory, the first thing is the coordination of the siege departments, the day of the coalition army Dong Cao Mengde led the army to attack the water pass is worthy of our army's reference, when the log is also in the array, its formation is very wonderful, the infantry is located... In Liu Yi's heart, the Vermilion Bird Battalion is his artillery unit in this era, and the battle must be kept improving, and he is also very pleased to hear Li Tieniu's words, but he can't imagine that he has used the knowledge of later generations to transform the sophisticated equipment and make the entire level of this era progress, otherwise the stone truck will not appear until the Battle of Guandu, of course, its prototype appeared earlier. After all, the combat equipment of the cold weapon era is an auxiliary factor, and the key is still related to the strength of the troops and whether the command is appropriate, so he also explained in detail the arrangement of Cao Cao's attack on Bishui that day, which was also his first attack since joining the army.

"Lord, this Cao Mengde is indeed a military law, but in terms of Jiaguan's ability to siege the city, General Gao is not under it, and this attack on Nanpi is still a foolproof strategy for General Gao to show his strengths." After listening carefully to Liu Yi's explanation, all the generals had a look of admiration on their faces, to know that the siege troops commanded by Cao Cao that day were not exactly his subordinates, and its deployment ability can be seen, after Liu Yi finished speaking, the generals were also thinking in their hearts, Guo Jia said at this time, Liu Yi participated in the princes to discuss Dong, he had not been like-minded, but Gao Shun led the army to attack the tiger prison but saw it with his own eyes, its tactics are endless, and the deployment of soldiers may indeed be beyond the reach of people.

"Feng Xiao's words are exactly what I want, and I just said that Cao Mengde's siege was also for Jing Fang to learn from, this time Jing Fang mainly deployed siege troops, and everyone was assisted from the side, Jing Fang, I will give you a day, and you must come up with a detailed set of siege methods." In fact, Zhang Hetai and Shi Ci were all in the army when they attacked the Tiger Prison Pass, but at this time, the lord was present, and it was inconvenient for them to speak, and Feng Xiao had less scruples! Sure enough, Liu Yi didn't have any hesitation when he heard it, and said happily, he originally had this idea when the Liaodong battalion of the higher shuns came here, and the scope of military affairs was extremely wide, and no one could be proficient in everything, and giving full play to the strengths of his generals was exactly what he, the lord, should do.

"This... The lord can rest assured that he will come up with a strategy within one day. Gao Shun was a little hesitant at first when he heard this, this point is the same as Zhang Hetai Shi Ci's second general, and the lord naturally wants him to be the main when he is there, but seeing Liu Yi's happy look is definitely not a fake, thinking that he is an ordinary person, he accepted his order with emotion.

"The generals also need to be discussed in detail, and the iron bull will have to investigate on the spot, and it is tentatively scheduled to start attacking the city in the morning after tomorrow, but it is still necessary to test it a few days ago, so please remember." Liu Yi bowed his head slightly and said again, after all, how Nanpi's defense can only be understood through actual combat.
