On the historical plane, Zuo Si's "Sandu Fu" made Luoyang expensive for a while. Among them, there is such a sentence in Wei Dufu: Those who are in the body take Zhongxia as their throat, and do not take the side as their placket. Those who have been in the word for a long time take morality as their domain, and do not take danger as a screen. In addition, he also said: Although the Sword Pavilion is strong (嶚一作: risk), those who rely on it are not so deeply rooted. Although Dongting is wet, the one who loses it is north, and it is not so much that the lover governs the country.

In short: Luoyang is located, although there are many hills around it, but as far as the city is concerned, there is no dangerous terrain to take advantage of.

However, the largest city in the world in this era does not need too many geographical risks.

Thanks to the strong national strength of Cao Wei in the early years, when Emperor Cao Rong of Wei Ming was in power, he implemented the policy of strong cadres and weak branches, and used the power of the world to repair Luoyang City. Therefore, compared with the population of Chengdu, the capital of Shu Han in the past, when it was only about 200,000 at its most prosperous, Luoyang had a population of more than 600,000 in its heyday. Compared with the city wall of Jianye, the capital of Eastern Wu, which has not completely surrounded the whole city from the founding of the country to its demise, the city wall of Luoyang is more than four zhang (nearly 10 meters), not to mention, he still has two inner and outer city walls. The area covered by the radius is nearly 30 square kilometers.

Therefore, as a traverser, Guan Yi has seen countless real-life Ming and Qing ancient city walls and computer special effects in movies in later generations. But when he actually came to this huge city surrounded by rammed earth, he couldn't help but be shocked by the ambition of the rulers of this era and the creativity of the people.

This is the case for a broad-minded traverser like him. Ji Han's other generals and soldiers, especially the soldiers from Yizhou in Shu Han before, were even more dumbfounded.

"Da Sima, in the past, Ling Bo (Li Mi) sent an envoy to Luoyang to come back, saying that Luoyang City is high and deep, and the last general has no feeling, but today I see ......"

"Yes, such a huge city, although it is extremely difficult for the defenders to defend. But the city was so large that it could hold enough people and food. If it's a consummation, I don't know how much time it will take. ”

"Hmm." He and his generals rode horses and circled around Luoyang at ordinary horse speed, which actually took almost a whole day. Guan Yi only felt that his head was big for a while: this city, in addition to being huge and with deep walls, also learned from what he did in Yixian County before, and built many new salients - this is the fortress. Not only that, but the density of trebuchets on the walls of this city alone is enough to make people's scalps tingle.

His scalp was numb, in fact, Sima Yan and others in the city also had numb scalps. Because, Guan Yi came too fast.

Guan Yi received a report on the battle of Mainlandze on 30 January. According to the calculations of the monarchs and ministers of the Jin State, the five states of Hebei have such a large territory and such a powerful family. It will take months to straighten out these relationships. This side advanced to the vicinity of Luoyang with the Han army in mid-to-late March, and it was already from the perspective of anticipating the enemy's leniency, and it looked highly at Guan Da Sima.

However, Guan Yi and his army appeared outside the city of Luoyang on the first day of the third month.

In this world, there are two kinds of leadership. One is to be able to make very simple things very complicated, and the other is to make complex things very simple. The former is suitable for whitewashing, and the latter is suitable for doing practical things.

Ji Han up and down, of course, it is the one who does practical things to occupy the mainstream.

Thanks to the preparations that began a few years ago, the graduates of Longshouyuan Academy have just graduated at this time. Therefore, in the five Hebei prefectures newly included in the territory, Ji Han has no shortage of grassroots officials.

Since Ji Han was in charge of Guan Yi, he implemented the system of disabled veterans serving as pavilion chiefs, the most basic administrative unit heads. Therefore, there are precedents to follow for the placement of wounded soldiers or something.

Then after Guan Yi suggested to Liu Chen that he should choose the governor of the state, Liu Chen's reply was extremely fast, and the relevant officials immediately set off with the holy decree. Within a month, the history of the five states had all been put in place.

In addition to the documents appointed by the assassin history, Liu Chen also issued two holy decrees at the suggestion of Guan Yi: First, all the five states of Hebei will be tax-exempt this year! Starting next year, the upper limit of the tax on land occupation will be lowered to 20 mu. Second, the five states of Hebei will continue to implement the nine-product Zhongzheng system for one year, and whether to change to the probation system next year will be discussed!

The so-called new income of a regime is afraid that the new territory will be unstable, isn't it that the aborigines on this land are afraid that their interests will be harmed? Now I assure you that your basic interests will not be affected. So what are you guys making a fuss about?

Moreover, with Ji Hansi Wencao's insistence on preaching at the grassroots level over the years, plus a large number of wounded veterans moved into each pavilion as pavilion chiefs. The meaning of these two holy decrees is not afraid that the common people of the five states of Hebei are not clear.

The key point is that Ji Han also left 20,000 cavalry in Hebei, and among the commanders of these 20,000 cavalry, Huangfu Min may be a little better. This is Zhong Yuan, but he has been in Hebei for many years. The twists and turns in the family are clear! Which of you dares to jump out and make trouble? I know how many manors your family has, and where they are hidden, so it will not be too easy to destroy your family.

In this way, won't the five states of Hebei be temporarily stable? Since it's safe, why don't I rush to Luoyang as soon as possible? Do you really want to prepare food for a long cage defense?

On the first day of the first month of March, more than 105,000 troops of the Jihan and Zhou Front arrived in the north of Luoyang.

In the second year of the first month, after the Jihan Jizhou Front Army set aside a considerable part of its strength to deter the five states of Hebei, the remaining 50,000 troops also came to Luoyang City under the leadership of Zhao Tong.

On the fifth day of the first month, Zhang Yi, Zhang Zun and others led an army of 15,000 people (10,000 were added to the left-behind corps) to Luoyang.

At this point, the three major front armies of the Han army completed their division in Luoyang, with a total of 170,000 troops.

It can be said that this operation, although Ji Han has achieved great success in strategy. In less than two years, he took the five states of Hebei and completed the siege of Luoyang. However, the generals of the Jin Kingdom have also made great achievements in terms of tactics. When their equipment and horses were inferior to their opponents, and their own emperor was in a daze, they inflicted nearly 100,000 casualties on Ji Han at the cost of 25 or 60,000 people.

(Not all of these 2560,000 were killed, but at least more than 120,000 of them were surrendered.) ）

At this time, in the Jin Kingdom, no, maybe in the lonely city of Luoyang at this time, there were 80,000 people evacuated by Du Pre, 20,000 people withdrawn from Tianjing Pass by Yanghu Weiguan, 13,000 people brought back by Ma Long from Tongguan, and 20,000 prince's guards and 40,000 new recruits from Yuzhou at the end of last year. A total of 173,000 people.

Hey? Why did it take a long time, and the army of the Jin Kingdom was more than Ji Han?

But you have to think that the Jin State has invested more than 410,000 troops for this battle. And Ji Han is only 290,000 (230,000 in the first phase, 50,000 in the follow-up.) Zhang Yi led 10,000 left-behind legions to join again). Moreover, Ji Han still has 20,000 cavalry left in Hebei.

Moreover, Ji Han's army has been tested by many major wars. Among the existing troops of the Jin army, only Ma Long's troops and the original Jingzhou soldiers and Yangzhou soldiers led by Yanghu and Wei Guan could fight with the Han army in a dignified field. Therefore, in the case of equal numbers, the option of opening Luoyang City and winning a field battle with the Han army actually does not exist for the Jin State.

What's more, in the defenders of the Jin State now, there are no more formed cavalry units. And the Han army still has 20,000 elite cavalry who have survived hundreds of battles.

Therefore, when the Han army appeared near Luoyang, the only thing the Jin monarchs and ministers could do was to gather the people and close the city gates.

However, in the face of such a fortified city, it was to attack the opponent's capital with inferior forces. Therefore, how to fight this battle still needs to be carefully considered by Guan Yi and his subordinates.
