"Okay, sign the book."

At this time, don't say that there is no contradiction between the two, even if there is a real contradiction, they can't take care of those trivial grievances, and taking Lujiang is more important than anything else.

After everything was over, the two began to listen to the report of today's battle, and from beginning to end, Zhang Jaw turned his back, as if he didn't have the heart to listen to the battle damage report at all, but although he turned his back, he listened to the battle damage figure very carefully, after all, as a commander, he knew the situation of this battle very well from the beginning, but he didn't want to accept such a reality, but he wanted to know the final result of the battle in his heart.

The battle loss is very large, after all, it is the attacking side, almost reaching three to one, this number is definitely much larger than he expected in his heart, if it is two to one, maybe he is quite satisfied with the result of today's battle, but three to one such a large casualty, he can't bear it, from another angle, 50,000 against 20,000, less than three times the advantage of troops, if such a battle loss number continues, then the final defeat will definitely be them.

Lujiang's strong attack is definitely not a chance, so Zhang Liao's dissuasion he can only implement it now, whether he is willing or unwilling, in another way, but he is skeptical about whether this plan can succeed, if the internal guards fail to succeed and can't cooperate with the outside, then what should he do in the face of Lujiang?

"We can't always pin all our hopes on the internal guard, shouldn't we think about a few more filings, once it is unsuccessful, there is a second and third plan?" After waiting for everyone to retreat, Zhang Liao said to Zhang Liao, who was sitting upright on the side.

Zhang Liao, who was kneeling and sitting, had already gotten up and was about to leave, and when he said this, he sat down again, closed his eyes, and said: "Although our losses are great today, the situation of the Lujiang defenders is the same, and the change in the situation is after the Shouchun army joins the battle, so if we want to storm the Lujiang River, unless the Shouchun army is not heavy, but this is simply impossible, so even if we want to storm the Lujiang River, the first thing to consider should be to reduce casualties, so as long as we attack strongly, It is inevitable that the cost of casualties will be tripled or even more, unless there is some other way to solve the problems that plague us now.

"Otherwise?" Zhang Jaw stared at Zhang Liao, and couldn't wait to ask: "What other ways to attack the city, tell me quickly, as long as I can reduce casualties, I am willing to try any way." ”

"I once fought with Cao Cao in Pei County, their thunderbolts are extremely terrifying, if we can have such a siege weapon, let alone Lujiang, it can be said that there is no city in the world that cannot be attacked!"

"Thunderbolt, where do we find it? Counting on the waste of the armory, you don't look at what they have built, the catapult can't be compared with the thunderbolt, and sometimes it can even hit its own people, without a bit of crosshair, but if you can aim a little accurately, it won't be what it is now. Zhang Jaw scolded angrily.

"Now our Thunderbolt is more suitable for defending the city, and it is true that the siege is not quite suitable, but I believe that one day we will have our own Thunderbolt."

"Wen Yuan, it's useless if you believe it or not, ten years later, the Ordnance Factory will make a thunderbolt, is it possible that we have to wait until ten years later to fight Lujiang, let's say now, how to break Lujiang, this is the key!" Zhang Jaw said angrily.

"In addition to storming, there are actually other ways to siege the city, such as ......"

"Like what? Wenyuan, don't sell Guanzi! ”

"Tunnel, set fire!"

He understands that he has seen such a siege method, and arson is no stranger to it, that is, digging a pit at the foot of the city wall and burning the foundation of the city wall, as long as the city wall collapses in one place, then they can directly kill the damaged city wall into Lujiang City, and stood up suddenly: "Wen Yuan, why didn't I think of this." Zhang Jaw finally smiled, and said happily: "Yes, there are so many ways to siege the city, why am I just a fool who will only attack, wait for the internal guard, unknown date, tunnels and arson at the same time!" ”

"The tunnel must be hidden, otherwise it will be discovered by the defenders, and our troops digging the tunnel will be in danger, and burning the city wall is also a reason, I think this matter is better combined and does not have to be carried out at the same time."

"Merger? What is the merger method? ”

"Set fire to the foundations of the city wall, the normal situation is carried out on the ground, the troops stupidly dig up the soil at the foot of the city wall and start setting fire, and all these actions will be directly exposed to the eyes of the collection, so it is very easy for them to defend, there will be many ways to spread hot oil on the rocks and rolling wood, so the probability of success of such an operation is, but it is very low, even at a great cost, there will be no gain, and digging tunnels will also be risky, and the possibility of being discovered is very large, After all, it is difficult for you to avoid the eyes of the enemy when you dig out the soil, and if you dig from a long distance, the amount of work is too large, so the effect of using tunnels to siege the city is the most ineffective. ”

When he was in Yanzhou before, Cao Cao used a similar method to attack Puyang, but they discovered the secret of Cao Jun's digging tunnels through Cao Jun's transportation nickname, and then they carried out countermeasures, such as they also dug tunnels, so as to lead Cao Jun's tunnels to other directions, or simply directly destroy the tunnels, the effect was very good, but they were afraid that Cao Jun would dig multiple tunnels at the same time, or even dig tunnels from different directions, so they buried many large urns in Puyang, In this way, the sound of digging tunnels can be accurately detected, once there is movement, this time it is not to destroy the tunnels, but to directly fill water or even smoke, and finally Cao Jun can only give up the tunnels and attack in other ways. ”

The more he opened his jaw, the more his brows wrinkled: "How is this good?" Neither of the two methods you are thinking of can be used? ”

"No, I carefully considered the situation later, and based on my experience in defending the city, I finally thought of the only way that could succeed."

"What is it?"

"Dig tunnels and burn city walls!"

"What do you mean......" Zhang Jaw understood in an instant, and transferred the work of burning the city wall to the underground, so that the city defenders above would not find out their true intentions, and they were using multiple tunnels to create an illusion, so that the Lujiang defenders thought that they were going to enter the Lujiang River by digging tunnels, so that after they destroyed the tunnels, it might be too late, their city walls had been destroyed, and at that time, the Shouchun army would be able to drive straight into the Lujiang River, as long as it was a normal duel, without the protection of Lujiang City, Not to mention the Lujiang defenders, even if the Shouchun Army joins together, they can also kill them!

"It's up to you to do this Wenyuan, whether you can capture Lujiang or not depends on you." The look of anticipation on his face.

"Junyi, you have to be prepared for this matter, you have also seen the situation of the Lujiang River, such a deep moat, we have to dig a tunnel to dig under the city wall, then we must first cross the moat, and to cross the moat, we must dig under the moat.

This is just one of them, and such a deep tunnel, it will inevitably cause breathing difficulties, the soldiers digging the tunnel will not stay in the tunnel for too long, so our tunnel must be closer to Lujiang City, the better, but not too close, otherwise the enemy army can destroy directly on the city tower, so the amount of this project is too large, and it is extremely difficult to implement, so I can accept this matter, but you must not put all your hopes on the tunnel, the most important thing is that the internal guard can be combined inside and outside, This is the easiest way to siege the city, and the tunnel is the way to do it, so I can do some preliminary work first, and after the internal guard can't do it, we will follow up on the tunnel to break the city at the end. ”

"Okay, just do as you say!"

Zhang Jaw and Zhang Liao sent him away after the discussion, fortunately there was Zhang Liao in the attack on Lujiang, otherwise he would really be helpless, after sending Zhang Liao away, looking at his back, Zhang Jaw was glad to think in his heart, no one can understand his mood at the moment, if Lujiang fails, he really has no face to see the lord Liu Lan.

This is a battle that ruined the reputation of the first world, Zhang Jaw returned to the big tent, entered the inner tent and sat down on the marching bed, wanting to rest, but he couldn't sleep after tossing and turning, sat up, opened the map, although Zhang Liao said that he was counting on the internal guard, but all he was thinking about in his heart was authentic.

And if you want to dig tunnels, it is best to dig dozens at the same time, so that it is hidden, and it can also confuse the enemy, so that they can take the bewildered tunnels seriously, so as to create conditions for the tunnels that really burn the city wall, and this is the best way to finally capture the Lujiang River.

However, as Zhang Liao said, there are many difficulties, and it is too difficult. Who would have thought that a mere Lujiang would make him helpless, if such a situation occurred in Shouchun, he would endure it, and it was Lujiang, so he couldn't say it.

He was a little unwilling, but there was nothing he could do, who let his troops be insufficient, if the lord had let Tai Shici go to the Wuxu Dock with them at the beginning, so that there would be no shortage of troops, and now he could storm Lujiang, without thinking about anything, and Liu Xun blatantly fought for consumption, who was afraid of whom, his troops were consumed, but now, he didn't have such confidence.

~~~~~~~~~~~

The messenger quickly whipped up and went straight to Guangling, and it was ten days later when he arrived in Guangling, when Liu Lan saw the documents of Zhang and Liao, he handed the letter to Xu Shu, who read it, nodded and said: "I think it is feasible to let the internal guards try." ”

The existence of the internal guard, although the original purpose is to collect intelligence, but there is also a special task, that is, when there is a situation like Lujiang now, they can come in handy, inside and outside, of course, this must be an extremely risky thing, if it succeeds, once it fails, everything they have experienced in Lujiang for many years will be turned into a shadow, so it is very difficult for Xu Shu to make such a decision now, but compared with the casualties of the soldiers on the front line, what is the price?

Seeing Xu Shu so selfless, Liu Lan became a little distressed, should he agree or refuse?

This price made him a little undecided for a while.

"Lord, don't have any worries, the current situation in Lujiang, maybe this is the only way to take down Lujiang, otherwise Junyi Wenyuan will not jointly write a letter, the difficulties they encounter must be very serious, you must respond as soon as possible, if it drags on for too long, it will be very unfavorable to our army, and it will be too passive at that time."

"Do you think this is the only way to do it right now?" Liu Lan shook his head, there must be a way, it will never be a way to only cooperate with the inside and outside, of course, if the inside and outside are successful, it will definitely be the maximum gain at the cost of the least loss, but nothing in this world is necessarily successful, while reaping the maximum return at the minimum cost, you also have to consider the possible consequences once you fail, as a general on the front line, they command to make the final consideration for the outcome of the battle, and as the commander of the rear, he needs to take into account the entire campaign to make a judgment, Find a balance between cost and return. ”

"Is a small Lujiang worth such an adventure?" Liu Lan looked at Xu Shu, if he wanted to make a final decision, if he wanted to agree, then first he needed to be persuaded to make him feel that even if he paid some costs, the risk of these costs was worth taking compared to success.

"Lujiang is the last unit of Yuan Shu in Shouchun, as long as Lujiang is broken, it is bound to be able to play a role in killing chickens and monkeys, at that time Shouchun will not be attacked, and Lujiang is not broken, Yuan Shu will have a trace of illusion, in addition to Zhang Xun of Ping'a, he will definitely defend Shouchun, so even if our troops give up Lujiang now, it is impossible to take Shouchun, not to mention that the lord forgot to defend the river and guard Huai first? Lujiang must be won, no matter what the price is, otherwise what is the meaning of our battle? ”

"That's all there is to it?" Some decisions are difficult for Liu Lan to make, after all, this is a very big price that may be paid for the elites of the internal guards, but Xu Shu has already said that here, even if it is not for Shouchun, only Lujiang is one city and one county, it is worth the risk!

You are the commander of the previous internal guard, since you agreed and made a decision, then I also agreed, you will now pass the order to Zhang Liao and the commander of the Lujiang internal guard!

"No!"

Since the order, then first of all, let the two sides get in touch, in what way, so that there will be no mistakes in attendance, one has already created chaos in the city, but the other party is not ready, so this tacit understanding is either through him to be the intermediary, or let the Lujiang internal guard directly get in touch with Zhang Jaw, only in this way, can it be safe, or only the direct dialogue between the two sides can ensure the final safety.

Xu Shu finally made the decision to put the two of them in direct contact.
