Taking the Central Plains directly requires a huge military base.

Once the war broke out in the Central Plains, the only strategy that the Mo family could choose was to quickly break through each and solve one before the countries joined forces, which was beyond the strength of the Mo family and the number of political cadres at this time.

Whether it is the concept of flanking and then forcing back proposed by the General Staff before, or the concept of outflanking and dumpling dumplings on a large scale and using defense as an attack to solve the Central Plains problem at one time put forward by Six Fingers, the center of the revolve is the strategy of "abandoning the Song Dynasty, leveling the battle line, turning the salient into a concave moon, lengthening the battle line, and flanking it".

For example, if the Song state was brought under direct rule, and only the military was discussed, not economic and political issues, then in Shangqiu, Lankao, Jiyang, and other directions, it would be necessary to invest troops, finance, and material resources again to build cities.

The art of war cloud, the left is doubled, and the right is empty; The front is doubled, and the back is empty; Everywhere is doubled, and everywhere is empty.

Once the Song State fully controlled a large plain, the defensive lines and troops that needed to be defended would be multiplied geometrically.

The Heze Taoqiu defense line on the northern front cannot be moved, and more troops are needed to maintain the line from Lankao and Jiyang to Heze, which is unbearable financial, material and manpower.

If the manpower, material and financial resources of Sishang can ensure that they can fight against the princes of Wei, Chu, Han and Qi in the Central Plains, and push all the way, then the Song State is the best bridgehead; If it is not enough to do this, but it is still necessary to do this, then it will be the Mo family itself who will be broken by the lack of troops on all sides.

Therefore, it is hoped that the upper echelons of the Mo family will be able to figure out the reasons why abandoning the Song State and maintaining the Song State is the rule of the vassal state.

It is necessary to use the Song State as a buffer country to continue to build Dangshan and Fuli cities on the southern front, so that once a war starts in the direction of the Central Plains of the Song State, the Mo family can abandon the Song State, stretch the battle line, and look for fighters to destroy the enemy.

As for the southern route, it is south of Fuli and goes all the way to the Surabaya into the Huai area, which is the key area of Wu Chu and Wu Yue in the struggle for hegemony before.

The effective rule of the Chu State in the eastern part of the Huai River is also to Zhongli, and after Zhongli is the Mo family's decision.

And because Qin did not get Bashu and did not break through Yingdu, the ruling center of gravity of Chu was still in Jianghan and Nanyang, and the strength of Chu in the lower reaches of Huaishui was very insufficient.

Because the Yellow River has not yet taken Huai into the sea, Hongze Lake has not been formed at this time, but a large piece of good land, east of Zhongli, along the Huai River, where the Mo family previously set the Nanzheng, Xiangyang, Tongbai Mountain, Huai River strategy to launch the attack.

In the Bronze Age, the Hongze Lake area, which had not yet been formed by the Yellow River taking over the Huai into the sea, was a settlement of fugitive peasants and so-called "bandits".

Small and large lakes, humid and warm climate, and excellent soil made it one of the best granaries of the Iron Age, but it was not suitable for human habitation during the Bronze Age.

In the past, Sishang had organized a large number of immigrants to enter Huaishui, and even implemented the "long-working" trade, transporting a large number of people from afar to enrich the area, strong organization and execution, as well as the lucrative background of private capital and "long-working" trade, all made the development here very fast.

Twenty years of peace, land reform, high-yield crops, iron farming tools, and other factors such as flight from other places and human trafficking in the south have led to a sharp increase in the population of northern Jiangsu.

The premise that northern Jiangsu was a rich land in the agricultural iron age was that the Yellow River should not be seized into the sea, or after the Huai River was seized into the sea, the government had enough organizational strength to thoroughly control the Huai River.

As long as one of these two points is achieved, the northern Jiangsu region is one of the best granaries, and history has continued after the Yellow River seized Huai in the Song Dynasty, which made this area gradually depressed.

Now the north gate of the entire plain area, Yimeng Mountain, is in the hands of the Mo family, and the Heshui and Surabaya areas, which are the easiest to break through along the line, are also the center of gravity of the Mo family's rule, with sufficient troops and stable defense, which provides a solid foundation for the next strategy.

Taking the Hongze Lake area as an example, Zhongli of Chu is not far away, and beyond Zhongli along the Huaishui to the west, there are two important cities of Xia Cai and Shouchun.

After taking Cai Shouchun, in fact, the only one who prevented the Mo family from seizing Sanguan and reaching Xiangyang was the "Shenxi Division" of Chu State.

Shenxi's division is similar to Chen Cai's division, both of which are field regiments under the county metric system similar to the governor's system in Chu, and the power of the feudal monarch here is very strong, but because of the barrier of Dabie Mountain and Tongbai Mountain, if the Mo family storms Shenxi along the Huai River - that is, the Xinyang region in later generations, in fact, the field groups of the Chu State are divided.

The main force of the Chu State, the elite of Che Guangdu, is in the capital of the Chu State.

If the troops of the powerful nobles such as Ejun and other places want to support the Shenxi area, they must go to the Dabie Mountains, where it is difficult to pass, in fact, the Shenxi division and the Chu army in the Wuhan area of Hubei are divided by mountains and rivers.

Chen Cai's division was on the front line of the Song, Wei, and Han Central Plains, and they wanted to mobilize a series of negotiations such as diplomacy, and the most likely thing was to join forces with Wei and Han to attack Song to Pengcheng, and force the Mo family to withdraw in a way similar to besieging Wei and saving Zhao.

The focus of the Xiangyang, Tongbaishan, and Huaihe strategies, in fact, the Chu State also has the Shenxi Division, a field group with combat effectiveness, that can be blocked.

In fact, there are three prerequisites for this strategy.

First, with the Song State as a buffer, around the Song State, Heshui, Dangshan, and Fuli defense lines, the front line was extended, and there was the strength to defend and counterattack east of eastern Henan, and it could support the offensive of Wei Han and Chu Chen Cai's divisions in key areas. Use the mass base and the city defense to resist the attack of the Central Plains princes.

Second, the construction of the boat division and naval army requires that it be able to occupy the initiative in the Huai River and the Yangtze River, suppress the boat division of the Chu State, and divide the Chu State into Huainan and Huaibei, Jiangnan and Jiangbei.

Third, Fu Lisai, that is, Suzhou in later generations, was in the hands, and the Shuize area of Hongze Lake was the flank, forming the flank defense area of Dangshan, Suzhou, and Hongze on the southern line of Pengcheng, so that the division of Chu Chen Cai could not easily break through and threaten Pengcheng.

If Wei, Chu and Han join forces, Chen Cai's division will inevitably take the Central Plains Song State Line and make peace with the Wei and Chu coalition forces.

If Wei Han didn't make a move or didn't react, if Chen Cai's division had strong generals, he would probably attack Fu Lizhou to threaten Pengcheng.

Therefore, if these three points can be achieved, in fact, the strategy of first Chu and then the Central Plains has been basically completed.

Therefore, the next key work of Sishang is to jump out of the quagmire of the Song Kingdom, strengthen the defense of Dangshan, Fuli and other areas, and continue to develop the Hongze Lake area as a logistics base to replicate Wu Zixu's entry into Chu in the first battle.

The state of Chu seems to be vast, but in fact, it is divided into small vassal states due to political system factors and geographical factors of mountains and rivers.

Dabie Mountain and Tongbai Mountain lie between the Nanyang area and the Huaibei area, and the most important of them is the so-called "Yiyang Sanguan" in later generations.

In the past, Wu Zixu destroyed Chu, and it was also the breakthrough of the Pingjing Pass in later generations and the current Stygian Choke Pass.

It seems that the state of Chu is quite large, but in fact, it has to be divided into many divided areas such as Huaibei, Huainan, Yunmeng, Dongting, and Nanyang.

If Xiangyang is controlled, the three passes are broken, the division of Shenxi is annihilated, and the Huaibei of Sishang is controlled again, in fact, the situation of confrontation between the north and the south can be produced.

The three passes, the key point of the Huai and Han soldiers; Xiangyang, the fulcrum of the confrontation between the north and the south.

If you have three passes, you will be able to save the interest, and the Huai and Han will be integrated. If the three passes are lost, Shen Xi will be destroyed, and Chu will be divided.

The Mo family's turmoil in the Song Kingdom was actually attracting the attention of various countries and diverting their attention.

After the rebellion of Wang Ziding, the king of Chu had the ability to directly govern the Chen Cai region, but the Central Plains region was staggered, which was actually equivalent to Chen Cai's division being trapped in the Central Plains.

Chen Cai's division had actually become a field force that would be exhausted if any side of Wei, Han, and Si moved. It is impossible to prevent ink, Wei, and South Korea, and it is impossible to trust each other, and Jin Chu has been fighting for more than 100 years.

The premise of the shift of the ruling focus of the Chu State is that the Qin State controls Bashu and threatens the Jianghan Dynasty, which makes the Chu State move eastward to break the local political balance, otherwise the Huaihe region is full of feudal monarchs, and the key rear of the Chu State has always been Yunmeng Dongting and Nanyang.

For Sishang, the Pengcheng area has a 20-year ruling foundation and the highest degree of popular support, which is destined to solve the confrontation between the north and the south in the future, and it will not be in the direction of Nanyang Yiluo, but can only take the direction of Huanghuai, Shandong, and advance to the west and north.

The premise of taking Xiangyang as the center of gravity and directly inserting Nanyang Yiluo is that there is a unified political power in the north, marching in this direction, and cutting the north so that Guanzhong and Shandong cannot take the lead in the situation.

And Xiangyang defends and Si goes on the attack, which is a better choice for the world at this time, which has been divided into a world of great contention among princes.

If we want to make an analogy, once this strategy is successful, the south will be stabilized, and land reform and political power building will be completed.

Then the situation is like annexing Zhu Yuanzhang in the Lianghuai region of Zhang Shicheng.

Or like Zhang Jun and Han Shizhong of Lianghuai during Yue Wumu's Northern Expedition, he was comrade with one heart and one mind, and there was also a field group in the direction of Huaibei that was no less than Yue's army.

The Surabaya basin can either march north or westward, and use the Nanyang line as a corner, or occupy the plain and advance northward to close the plain area east of the Taihang Mountain, which is a feasible strategy.

The overall strategy was set 20 years ago, and the Mohists have not been stupidly waiting for "the world to change", but have taken the initiative to create opportunities and instigate contradictions in various countries.

Now that the Song Kingdom is making such a fuss, it can be said that the whole world will think that the Mo family will encroach on all countries little by little along the direction of the Central Plains of the Song Kingdom, but they never thought that what the Mo family wanted to do was swallow whales.

As for the two Huai River basins and the division of Shen Xi in the Chu State, it is not in the Mo family, but in the Chu State itself.

If you want to strengthen the defense there, you have to rein in the central power, which will harm the interests of the powerful aristocracy.

There was no way to rein in the central power, and there was no way to organize an effective defense in the Shenxi and Huai regions, and once the Mo family defeated the Shenxi army, the fate of the Chu State being divided was inevitable.

Originally, the sudden coup d'état and preemptive choice of the Song State disrupted Sishang's strategy of continuing to develop high cities and accumulate grain, but when handled properly, it turned disadvantages into advantages and attracted the attention of all countries to the Central Plains.

Now that it has been basically determined that it is impossible for Wei Chuhan to send troops together, the next step is to invest more energy on the southern front.

And...... continued to instigate the internal contradictions of the Chu State, and used various means to cause the contradictions accumulated in the Chu State to erupt due to the reform of the law.
