How to break through the Liangshanbo cottage is a difficult problem that has plagued Sun Tu in the past few months, at least so far he has not come up with a proper solution, just because the terrain of Liangshanbo is too good, even the elite of the Qingzhou army trained by him is not sure that it can really pose a threat to it.

Whether it is looking at the description in the book Water Margin about the Song Dynasty sending troops to attack many times, or the fact that Gao Xiang and others forcibly attacked the mountain, Sun Tu was a little unimpressed with their final defeat at first, thinking that it was the incompetence of these generals that led to the successive defeats.

However, two months ago, after he disguised himself and went to Liangshanbo to take a closer look, he found that he still underestimated the ease of defense and difficult attack of Liangshanbo.

Liangshan is surrounded by lakes on three sides, east, west and north, which makes the officers and troops have to choose to attack from the south if they want to fight up the mountain. However, the terrain there is extremely narrow and steep, which is not conducive to the spread of the army at all, but once the attacking troops and horses are reduced, or the team is lengthened to attack, it cannot pose much threat to the outskirts of the cottage that have long been strictly defended.

Sun Tu only glanced at it from a distance, and he could clearly see the many checkpoints standing on the periphery of the cottage, as well as the various blades that flashed with cold light on the walls of the village. He was very clear in his prediction, if the army really attacked head-on regardless of it, there would be only one end, and by the time they reached the opponent's wall, they would have suffered heavy casualties, and just shooting with bows and arrows would be enough to harvest the lives of a large number of officers and soldiers.

And this is only the outermost line of defense of Liangshanbo, and further up, there are still passes like copper walls waiting for the officers and soldiers. Unless the imperial court can send an army of 100,000 at all costs, and then fill in a passage with human lives, it will not be able to kill Liangshan Benzhai at all.

Of course, after confirming this, the idea of launching an attack on Yangsan from the waterway was also proposed. In this regard, Sun Tu also quickly gave an even more desperate answer, and still couldn't do it.

Because the waters around Liangshanbo for hundreds of miles are actually under the control of the other party, and the waterways in the lake are complex and changeable, and the reeds are overgrown, Mo said that there are not too many people in the Qingzhou army who can really fight water battles, even if they can really train an elite naval army, it is dangerous to send them in. You must know that the strongest group of men and horses in Liangshan Po is the sailors, and they can attack the officers and soldiers entering the lake from the two lines of water and water. In such an environment, the situation of the officers and troops will only be more dangerous on land, and they will not even be able to retreat, and the casualties will only be greater.

Moreover, even if the officers and troops can really successfully kill the other three sides of Liangshan through the waterway, because it is difficult to lay out the geographical constraints there, as long as the enemy attacks with arrows and stones above, the soldiers below can only be beaten passively, and the casualties cannot be smaller than the frontal attack.

Such unique geographical conditions, coupled with the fact that Liangshanbo itself has a certain combat strength, it is no wonder that the imperial court has sent troops to attack many times and ended in failure. It was only at this time that Sun Tu knew what a huge problem he had in front of him, which was one of the key reasons why he would rather resist the pressure of the imperial court and refuse to use troops against Liangshanbo.

But the problem here always has to be solved, so in the following days, in addition to continuous training, Sun Tu also discussed the strategy of attacking the mountain with many soldiers, but unfortunately after many days, he has never come up with a proper idea.

In fact, there are still some ideas, such as someone proposing an overnight attack, and killing the Liangshan thieves before they even noticed. However, soon this statement was pointed out that there was a big problem, because the official army could not do a surprise attack at all, the people of Liangshanbo were far smarter than everyone thought, they had already spread their eyeliner outside the mountain, and they also set up hotels in the four directions, not to mention that tens of thousands of soldiers and horses were approaching, that is, dozens of people appeared in that area, and the news also spread up the mountain one step earlier, so that they were enough to prepare for relevant defenses.

In addition, a more whimsical idea was put forward by the geography of the lake, which was to dig up the embankment of the lake where Liangshan Bo was located, and divert the water from the lake to other places, so that the moat would be a smooth path, so that the army could attack from other sides, which would be much easier than attacking the more defended south.

To be honest, when this proposal was said, Sun Tu was really moved. Although this is time-consuming and labor-intensive, it is very profitable and has the least casualties, as long as labor is sent to open the embankment and divert the water elsewhere.

But soon, he found out that this was just a "clever plan" on paper, because this Liangshanbo occupies too much land, although it is not as vast as the rumored 800 li shuibo, but it is also 100 miles square, which can be compared to a large and medium-sized reservoir in later generations. And if the water of this lake is released elsewhere, the harm caused will be too great, and I am afraid that the entire Jeju Prefecture will have to be put into it.

At that time, the displacement of the people will only be worse than the impact caused by the Liangshan bandits. Even if he can really destroy the Liangshan thieves with this, I'm afraid it will be too much more than the work, and it's not worth the risk at all!

After thinking about it and not being able to come up with a proper way, Sun Tu even planned to use the method in the book to directly recruit An Song Jiang and others in the name of the imperial court. However, this idea was quickly dispelled by him, and the hatred between his own family and those people in Liangshanbo had already been deep enough, Zhujiazhuang, Dongping Mansion, and Qingzhou City...... After these vicious battles, the leaders of Liangshanbo killed by his subordinates have long been counted, and they must hate themselves to the bone, how can they surrender willingly?

Even if Song Jiang actually has the intention of returning to the imperial court from the bottom of his bones, the current Liangshanbo is very different from the Water Margin story, because now Liangshanbo is still alive, and this person is much tougher when dealing with the imperial court.

In addition, because of the previous battles, Song Jiang suffered a lot of losses, so that his status in the cottage was not as popular as in the Water Margin, and many leaders who had a deep friendship with him died, which made it difficult for Song Jiang to raise the matter of recruiting in public.

It can be said that it is precisely because of the appearance of Sun Tu that the Liangshanbo incident cannot end peacefully, at least until they feel the inevitable defeat and the threat to their lives, it is impossible for these people to accept the choice of surrender.

So after a few days of discussion, the final conclusion returned to the original point - neither the use of troops nor Zhao'an could solve the problem of Liangshanbo, and the matter dragged on until Zeng Kaiqian arrived with the will of the imperial court, and Sun Tu had to shift his focus to Qingzhou.

While suppressing Zeng Kaiqian, Sun Tu did not completely let go of his strategy against Liang Shanbo. And during this period, he was inspired and thought of a perhaps the wisest choice at the moment-

Zeng Kaiqian actually wanted to achieve his goal of overthrowing him by winning over the generals under Sun Tu's command, of course, this would not work, but Sun Tu thought of here that he could also take advantage of the complex relationship between the leaders in Liangshan Bo to divide them from the inside!

Unlike the situation where Sun Tu is the main one here in Qingzhou City and the generals are convinced, the relationship between the people in Liangshanbo is much more complicated. Just because there are more or less contradictions and differences between the leaders with different identities and backgrounds, whether they are open or implicit. In addition, the two leaders of Song Jiang and Chao Gai actually have hidden problems, so Liang Shanbo, who seems to be a brother, has already been reborn with contradictions, but it has not broken out for the time being.

And what Sun Tu wants to do is to completely stimulate the contradictory relationship between some people, and then sit back and wait for them to have chaos inside the cottage! There is a good saying that a strong fortress is often easier to be breached from the inside, and the Liangshanbo in front of him is like this for Sun Tu. Since it seems that the strong attack from the outside is not very certain, it is better to start from the inside, to cause internal strife through division and instigation, and then cooperate with the army to suppress the border, maybe it can be pacified at a very small cost.

This is indeed the most reasonable and correct decision at the moment, but it takes a lot of thought about where to start. In fact, as early as a few months ago, Sun Tu had already made corresponding arrangements, but it was only because there was no news after the person left, that he could not find out the specific situation in Liangshan Village.

And this time, he had to find someone who was easier to use and who was also inside Liangshan to complete his crucial first step.

In fact, there is really such a candidate around him, after all, Sun Tu has received a lot of Liangshan's generals before, and after some consideration, he finally called a guy who has not been reused to him: "This official has an important thing for you to do, as long as it is done, you will be the first merit." ”

The person on the other side was still a little frightened, but when he heard this, he suddenly came to his senses: "Please also give orders from the superintendent!" ”

"You should also know that this official has already been ordered by the imperial court to attack Liangshanbo, but if it is attacked, it is really not a little certain, so I plan to attack from the inside." In the other party's somewhat puzzled gaze, Sun Tu finally said the key: "What I mean is for you to secretly go back and see your brother, so that he can secretly have more contact with some undesirable leaders in the village, provoke contradictions in the village, and then cooperate with us to cooperate with the outside world!" ”

"This ...... My brother has always kept a low profile in the stockade, and he has been in the mountains for many years, how can he do this? ”

"Just go and see him, and you'll see. Mo seems to be a veteran of Liangshan, but in fact, the situation is quite bad. People who have no selfish intentions, as long as you teach me to you, I believe he will make the wisest choice. Sun Tu looked at each other with a confident face.

Since Sun Dujian said so, this naturally did not dare to disobey, so he responded immediately. Soon after, he set off for Liangshan.
