After the Han army reached the city of Shouchun, Li Su immediately divided his troops to siege the city, set up a camp and set up a corridor, and deployed a long-term battle plan.

In contrast, those jobs such as creating trench machines, ladder trucks, siege hammers, and city-digging wooden donkeys are not in a hurry. It can be seen that Li Su was mentally prepared as soon as he came: as long as Cao Ren wanted to stick to it, the battle should not last for a long time, so it is more important to lay a solid foundation first.

Of course, at the same time, Li Su also sent messengers and scolding players to try it out with a mentality of not having a date or not, and shouted and persuaded the city to surrender from afar.

He said that as long as Cao Ren abandoned the city, he could spare him from death, and allowed him to take away the remaining troops in Shouchun City.

What if the other party is shaken?

Unfortunately, the accident did not happen. This persuasion was indeed useless. Even Cao Xiu knew that he wanted to fight for the Cao family, let alone Cao Ren, the number one stubborn defender of the Cao family.

However, the building of the corridor was also idle during this period. It was not a waste of morale after the curse and the attack. By the way, it could also spread the miserable situation of Cao's army and the news of his defeat and annihilation into the city, causing panic among the defenders.

...

On the eighth day after the siege began, on June 28th, the camp and corridor had been completely completed, and the assembly of the catapult array had been carried out for two days, and other Yunlaid wooden donkeys began to be built on the spot.

The trench operation used for siege has not yet begun. Because the construction of that thing takes time and lasting, it is often not used in the early stages of a siege battle.

Once used, it will take at least two months to break a city. If it is slow, it is also possible for three or four months. The advantage is that it can minimize casualties and make the offensive effect more stable.

Since Zhuge Liang invented the approach of the Z-shaped trenches, the Han army has only used this tactic twice in one year in Jicheng, Youzhou Prefecture, and the main front-line front-line battle battlefield of Yancheng.

If Shouchun in front of him ends up having to use it, it will be the third time.

The construction of the siege was progressing so smoothly that Li Su, as the prime minister, had nothing to do every day and could only be the supervisor of the military discipline. At the same time, he took time to deal with the work of appeaseing the people in the newly occupied areas and resume production.

Considering that Cao Ren had just robbed the early rice harvest of the people in Huainan near Shouchun and gathered into the city, people's livelihood work is also necessary. Otherwise, it is possible to die of starvation and plague epidemics in the Lianghuai area this year.

A large part of the plague in ancient times was that a large number of people died and no one buried them after death, which caused the outbreak of the virus.

So after a large-scale famine, 200,000 to 300,000 people starved to death, so many unburied corpses became sources of decay and poison. In the end, the plague spread and a total of nearly one million deaths were possible.

A while ago, Li Su surrounded *** and the days in Shouchun were just the time to plant the late rice after harvesting it. So Li Su had to divide his 60,000 army into some men to help the people of Huainan who had missed the farming season due to the war and rushed to sow seeds.

People who have been in rural areas in the south know that rushing to harvest and planting is the busiest time, and this period requires a lot of extra labor. Even in the 20th century, rural areas will also have busy farming leave at this time, and children will have to go back to help farm.

Although Li Su's tens of thousands of strong laborers and the number of people transporting grain with the army has eased the labor shortage of Huainan people. Even if the late rice this year still fails to grow it a little late, it is better than missing a season completely.

Especially the early rice harvest was completely robbed by Cao Ren, and the people could only survive the surplus grain that was not available for the green and yellow, but now they have to hold on for nearly four more months, and it is certainly inevitable that people will starve to death. Li Su's actions were only alleviated, and it was impossible to completely solve the problem of starving death.

What Li Su could do in the end was to let new local officials and garrisons go to various places to promote the court's benevolent politics, saying that this year's late rice will be completely exempted from taxes, and at the same time, we must make it clear to the people:

Although they were actually "divided into taxes for 55" this year, specifically manifested as "all early rice was robbed and no tax was required for late rice", the ones who robbed them were Cao Rengou Thief, and the ones who were exempted were Prime Minister Li and Zhuge Shangshu.

As long as the surviving people can remember this simple truth clearly, the people's hearts in Huainan area will be completely subdued by the court next year.

In fact, the people's hearts have been quite useful just now.

Every household in Huainan countryside kept scolding Cao Ren, and millions of people cursed Cao Ren without any anus, and the whole family had no children and grandchildren.

And these curses are expected to be realized soon.

...

In addition to the above-mentioned civil affairs appeasement work, Li Su's last job was to inspect the city every day to prepare for siege and detect loopholes in the city defense.

However, after a few days of inspection, he really didn't find any obvious loopholes.

Cao Ren's ability to guard the city is also first-class among the famous generals of the Three Kingdoms, which is normal.

In the evening of that day, as another day of patrol was over, the group finally stopped on a catapult assembly position about 400 steps away from the city wall. Put down the telescope, and there were busy engineers next to them, barely installing the batch of catapults.

It happened that Zhuge Liang was also accompanying him, and Li Su couldn't help but sigh:

"Shouchun is worthy of being the strongest city in the two Huaihe Rivers. It was not unreasonable for Yuan Shu to regard this as a false capital. Compared with this, Hefei's city defense is nothing.

Cao Ren's persistence technique is also very serious. Maybe this city will eventually rely on A Liang's winding trench tactics to make the crossbowmen and catapults approach the bombardment, thinking that it will take a long time to do so."

Zhuge Liang finally confirmed the terrain, put down his telescope, and said cautiously: "The student's method of trench siege successfully broke Jicheng last year, but he can break Yancheng again recently.

But things are only three. The geography is different from each place. If you want to use it for the third time in Shouchun, you may have to solve some difficulties in adapting to local conditions. You can see that Shouchun City is bordered by the Huai River and is a little far away from the city and is low-lying.

The city itself is built on the platform, where the Feishui River and the Huai River flow here. It is because the platform where Shouchun is located is high and the west of the city is rapidly lowered, and a gap has occurred, causing the Huai River to diverge water to flow south.

With the Huai River and the Feishui River blocked, the north and west of the city were all surrounded by rivers, and it was impossible to attack. After passing through the city, the Huai River turned slightly south, blocking more than half of the wall section in the east of the city.

So what we can attack now is the entire south of the city, plus a small part of the city wall in the south east of the city. The attack surface is so narrow that it is very conducive to Cao Ren and our army's war of attrition.

To defend such a city, there is not much force required to use, and the enemy can lose some and then fill it up to prepare the team.

In addition, we can only attack the south of the city, and the south side is low-lying. From the origin of the Feishui River, our army can see a water-keeping lake, which was built by Sun Shuao, the emperor of Chu during the Warring States Period.

Shaobi is different from a natural lake. Its water comes from the upper reaches of the west side and comes from the remaining veins. The water level on the lake is higher than the depression in the south of Shouchun City. At that time, the Chu people operated between Chen and Cai, and adjusted the water level to ensure irrigation. Therefore, it is necessary to repair the embankment on the east bank of the lake at all times, open the mouth of water to irrigate during drought, and store water to intercept flood peaks during flooding.

Now in midsummer, it is rainy season. The embankment on the east bank of Shaobei is destroyed and water is poured down. All construction in the depression in the south of the city is in vain, and all the soldiers are fish and turtles.

If our army wants to attack Shouchun for a long time, the key is to first ensure that no enemy damage can be leaked on the east bank of Shaobei. The lake is 100 miles apart, and our army must patrol everywhere. As long as the destroyers penetrate a little successfully, how difficult the gap is so huge?

Even if Shaobi is prevented from being destroyed, our army must prepare for rework and scrapping during construction, because the amount of groundwater in Shouchun depression is not comparable to that in Hebei, nor even comparable to Yancheng.

The wetlands in the south cannot be dug, and even the open trenches require a lot of extra disposal, which is definitely more troublesome than the north."

Zhuge Liang is worthy of being a master of siege. After a few days of observation, he explained one, two or three advantages and disadvantages, which made Li Su feel worry-free and reliable after hearing it.

With A Liang here, you don’t have to worry about checking for omissions and filling in the gaps. All risk assessments will be clearly done for you, and there will definitely be emergency plans.

Moreover, after being explained by Zhuge Liang, Li Su has a new understanding of the solidity of Shouchun.

No wonder there are so many north-south separatist situations in history where the rivers and the Huai River must be defended. This place can serve as the most solid support point for the north-south frontline.

Imagine how long Zhou Shizong Chai Rong fought with Liu Renzhan from the Southern Tang Dynasty here in the late Five Dynasties and Ten Kingdoms. Liu Renzhan died and was lost in Shouzhou. The remaining fourteen Huainan prefectures in the Southern Tang Dynasty were almost instantly killed.

There are many examples of such stalemate wars between the two dynasties in the north and the south in history.

In addition, Li Su also played "Romance of the Three Kingdoms 11" in his previous life. Players who played that generation should be familiar with the design of Shouchun City:

In the game, there are two grids in the wilderness of Shouchun City, which are "dams". After the troops attack the dam completely smashed, the lake will surging down, drowning all the troops outside the city, and they will be killed directly, without any additional judgment.

Now that I have seen it with my own eyes and listened to Zhuge Liang's explanation, Li Su realized that Japanese game designers are quite research-based. Shouchun City Battle can indeed do this. The water storage lake he dug was built in the Spring and Autumn Period.

Since ancient times, digging tunnels and trenches in the south are more difficult than in the north. Even in the 21st century, cities along the southern rivers will hit plain terrain, and the cost of building a subway is much higher than that in the north.

Therefore, the method of trench siege that has been successfully successfully twice is to be reproduced here, and of course, we must overcome new problems again.

No wonder Cao Ren was fearless and insisted on sticking to it for a long time even so.

After careful planning, Li Su ordered: "After building enough for the catapult and the city-digging wooden donkey, we will first try to siege the city for two days. If it is indeed solid, we must deploy trenches to siege the city.

Regarding the problem of water in the trench, I will find another way to prepare leather boots with waterproof glue paint for the crossbowmen to avoid excessive sewage and contagious disease. Then ask the military carpenters to cut more tree stumps or build wooden benches to dig deeper the trench. In wartime, let the crossbowmen kneel on the wooden trench and shoot arrows.

Finally, before the war begins, we must completely eliminate the remaining enemies in other directions outside the city, and ensure that there is no other enemy support except the defenders in Shouchun City.

In this way, as long as we surround Shouchun and prevent Cao Ren from sending a team to destroy it, we can ensure the safety of Shaobi. Of course, our army's patrol team must also be kept on guard every day to ensure vigilance.
