On the sixth day of the second lunar month, it was the evening of another day.

Zhuge Jin rubbed his shoulder, which was slightly sore because of the hard work of the case, wrote another page of "Precautions for the Reconstruction Planning of the Hangou Canal", checked it slightly, and then threw it into the wooden box on the side-

This box can be brought after Zhenrong's death and when the second brother goes to Guangling to report the victory and meet his stepmother.

If it is not smooth to help Liu Bei and Chen Qun deal with the water control matters, they can take it out as a reference book.

Zhuge Jin doesn't know much about water control, he just based on his mathematical knowledge and what he saw when he watched popular science videos in later generations.

If you think of a point, add a little bit, and try to reduce the difficulty for Zhuge Liang to get started.

Zhuge Jin had just finished all this, and Zhuge Liang had finished another day's apprenticeship and training, and hurriedly rushed to the main hall.

Zhuge Jin called out to him and asked casually: "How many days has Xingba been surrounded?" Haven't moved yet? ”

Zhuge Liang: "Four days, today is the fourth day." Zhenrong tried to attack the day before yesterday, but he retreated without progress, and Xingba always set up a black flag at the top of the peak, which was a signal agreed before departure - if the situation was critical, the red flag would be changed. ”

Zhuge Jin touched his nose: "That Rongrong is just like this?" If Xingba doesn't trouble him, won't he be impatient? For example, did you divide your troops to plunder the four wilderness townships? ”

Zhuge Liang: "This is not true, but the scouts reported that the Zhenrong army has gradually become impetuous, the soldiers are in and out of order, and the military discipline is a little difficult to restrict." ”

Zhuge Jin put down the cup he drank just now: "In this way, Zhenrong's impatience is about to explode, Xingba is so close, he should be able to see it, it is estimated that he will definitely come tonight...... I don't worry about anything else, just worry about whether his morale will be low enough to carry out a counterattack after being surrounded for four days. ”

Faced with the eldest brother's worries, Zhuge Liang hurriedly comforted:

"No, it won't! Big brother rest assured, under the command of Xingba, most of them are people who are obsessed with fame, we give such a heavy reward, and draw such a bright future, they will not work hard. ”

Zhuge Jin touched his embarrassed beard: "Is the reward we give very high?" It's not five hundred yuan per person, I also gave it according to the amount suggested by General Guan, he said that in the original desperate situation, he needed soldiers to fight to the death in other places, and he also gave it. ”

Zhuge Liang smiled when he heard this: "Big brother, at this time and that time, you have forgotten the method of 'helping soldiers save money' that you came up with, since you have that method, the soldiers have cherished money more, and they are not so lavish in spending money." The same amount of reward, but the effect is much better than usual-

At this point, General Guan has been sighing for the past few days, saying that although you have always been humble and do not know how to govern the army, your use of rewards is beyond the reach of the ancients. With that perfect method of saving money, he has surpassed Huo Qu's illness. ”

Zhuge Jin was stunned for a moment, and asked some details again, and then he suddenly realized.

Before the design of the system of helping soldiers save money and remit money appeared, if the soldiers of the Han Dynasty were single in the army, and their parents were far away, they had the habit of spending lavishly.

They are afraid that they don't know which will come first, accident or tomorrow, and if they have a life to earn money and no life to spend, it will be in vain.

So much so that the consumption of wine and women next to the barracks was always very vigorous and the prices were inflated.

As Clausewitz, the aide-de-camp of Napoleon's old rival, General Scharnhorst, wrote in his memoirs:

"As soon as the Battle of Austerlitz ended, those despicable Polish merchants who were seeking profit dared to take brandy to the French barracks to peddle.

And even if they sold a glass for 6 francs, the French soldiers, who were paid only half a franc a day, still flocked to them—it can be seen that those who had just escaped from the hands of death were willing to numb themselves with a glass of liquor for twelve days' daily wages. ”

After Zhuge Jin invented the above-mentioned system, the effect was immediate the next day: the merchants selling wine next to the Chaisang camp directly reduced the price of each bottle of wine by more than 20%.

And the value of the women who peddled the soldier's business plummeted by a third.

In a word, the savings rate of soldiers skyrocketed in an instant, leading to an instant downturn in luxury consumption.

On the one hand, this led to the fact that even if the soldiers wanted to spend, the money became more valuable, and deflation.

On the other hand, the soldiers also cherish money more in their hearts and treat it as money more.

And these two economic phenomena will further lead to "rewarding soldiers with the same money, buying more favors and loyalty".

Guan Yu asked himself how to reward Shang Yinghuo for more than ten years to maximize the incentive effect.

Unexpectedly, in the end, it was better for Zhuge Jin to invent a system to help soldiers run safes, so that the morale improvement effect of money skyrocketed by several percent in an instant.

This is like if it can be as digital as in the game, after Guan Yu "rewards 100 taels", you can see a "loyalty +10" popping up on the head of the troops, and the same 100 taels will be rewarded by Zhuge Jin, but the effect obtained is "loyalty +15".

With such an ungodly promotion, how could Guan Yu not say that Ziyu had surpassed Huo Qubing in reward efficiency?

After Zhuge Jin pondered and understood these twists and turns of economic principles, he couldn't help but laugh at himself:

"So my reward efficiency is already so good? That's really unintentionally inserting willows into the shade, I don't even know that I can let Xingba's corporal work so high. That being the case, let's see Xingba's performance tonight. ”

……

Zhuge Jin did not wait in vain,

He and Zhuge Liang were able to scout through scouts and found that the Zhenrong army was camping around the north peak of Lushan, and they were already impetuous, and their military discipline was slack.

Gan Ning was on the top of the hill and looked down at the enemy's movements, how could he not see it?

So, that night, on the fourth watch, Gan Ning suddenly organized more than 100 people, quietly touched the mountain slowly, and walked the safest mountain road to ensure that the soldiers would not step on the cliff.

Because it was a dark night to walk down the mountain, it was very dangerous, and the number of people must not be large, otherwise they would trample on each other and roll down the mountain.

It took a long time to quietly touch the foot of the mountain.

After a short rest and the whole team, Gan Ning personally threw out the hook and tore over one of the antlers at the door of the enemy's camp, and the henchmen next to him also did the same, removed several antlers, rushed in through the gap, and then began to set fire.

Since it was not cavalry, the effect of chaos was not so good, and it was all about setting fire to expand the results of the battle. Gan Ning didn't dare to stay longer, burned a hundred and ten tents, took advantage of the chaos to kill and wound hundreds of enemies, and when the two battalions of enemies on the left and right reacted and rushed here for reinforcements, Gan Ning immediately collected his troops and returned to the mountain.

It took a long time for the Zheng family army to restore order, and it was not until dawn that the losses were finally counted. Furious, he ignored the care of his eldest brother and launched another attack on the mountain, but sent some soldiers in vain.

In the end, he melted over and pressed it again strongly: "Don't be reckless!" Last night, if you didn't let the Ganning dog thief break through, it was a victory! Forget that we have to destroy the enemy by besieging and cutting off food and water! Gan Ning's breakthrough just shows that he is in a hurry! It means that he is out of water! Shows that we're doing it right! ”

The Zheng family army was subdued by this reasoning, stopped for another three or four days, and was provoked again in the middle, in short, they were always beaten in vain, but they could not launch a counterattack, and their morale was simply extremely low.

From ancient times to the present, the most demoralizing situation is to be unilaterally beaten in vain, but unable to fight back.

Even if the loss caused by this kind of beating is not large, the anger in the heart of the person who was beaten cannot be soothed at all.

……

In this way, it dragged on until the tenth day of the first month of February, and Gan Ning had been besieged for eight days and eight nights.

No matter how low Dirong's IQ is, at this moment, he should realize that he has been tricked - if Gan Ning is really short of water, can he continue to hold out for so long after the first breakthrough failure to shrink back?

And the anger that has been frustrated all the time when he found himself being played like this is almost going crazy.

"Zhuge dog thief! Dog thief! How dare you sell flaws so deliberately for me to drill! Resume the original plan, and tomorrow while continuing to besiege the north peak of Lushan, while dividing the troops into two divisions, to plunder the four fields.

Slaughter all the people outside the city that I can find! Force Guan Yu to fight me immediately! Decisive battle! We can't let the dog thieves of the Zhuge family lead us by the nose anymore! Well, the detached division that plundered and slaughtered, and did not run too far, so as not to give the enemy an opportunity to take advantage of it, and must return before nightfall to join the main force. ”

The other generals of the Zhenjia army finally had something to do, and these days they were also extremely depressed, and hurriedly received the order, which was going to loot and slaughter.

After the Zhenjia army had a new movement, in Chaisang City, twenty miles away, of course, it was the first time to get a report from the scouts.

"General Guan, it's not good! Zhen Rong finally couldn't hold his breath, it is estimated that he found out that he was tricked by Gan Duwei, he suddenly sent thousands of people on the left and right sides today to burn, kill and plunder everywhere, how can this be handled? ”

After Guan Yu got the news, he also attached great importance to it, and while preparing the troops to attack, he said hello to Zhuge Jin and Zhuge Liang.

When Zhuge Jin heard this, he just asked: "Can the troops attack at any time?" Are you sure? ”

Guan Yu: "Yes!" These days, although I am still practicing and motivating the military every day, I have let the soldiers be strict and ready to attack at any time! ”

Zhuge Jin: "Then it's not bad for these two days, change the plan a little, and attack in advance." We are the king of benevolence and righteousness, and we can't watch Zhenrong slaughter the people and avoid war. ”

Guan Yu didn't speak again, just solemnly arched his hand, flicked his cloak, turned around and got on the horse.

……

On the morning of the 10th day of the first month of February, the Dijia army went out to burn and kill the plundered division in two directions, and had just walked for more than an hour.

Zhen Rong himself was still sitting firmly in the Chinese army camp on the plain directly north of Lushan, and did not perceive the danger in the slightest.

In a ring of large camps besieging the north peak of Lushan, 40,000 troops were originally stationed at full strength.

But on the day the army came, it was ambushed and lost several hundred, followed by three tentative attacks on the mountain, and two robbed camps by Gan Ning, adding up to thousands of losses.

So until early this morning, in fact, there were only 35,000 or 6,000 troops in Zhenrong.

Just now, he divided his troops into two ways to burn, kill and plunder, two or three thousand each, and there are only 30,000 people in the camp at this moment, and they are still stationed in four directions to surround the north peak of Lushan.

The camps in the east, west, north, south and north directions of the mountain peaks can gather more than ten miles apart from each other at most, and even if there is a little accident in a hurry, they can't rush to support at the first time-

Even in the modern army of the 21st century, it takes about 20 minutes to run a 5-kilometer march lightly.

The distance was longer, the equipment was heavier, and the physical fitness of the soldiers was poorer, and the army of the Han Dynasty had to rush to reinforce when such friendly camps were attacked, at least for nearly half an hour.

When he was doing nothing, he suddenly heard a rumbling sound from the north, which was faint at first, and then became more and more obvious. When he really wanted to ask, the third brother rushed in with scouts.

"Big brother, the scout returns, Guan Yu personally led Chaisang's main force out of the city and came straight to our camp!"

"Is it finally here?!" Zhen Rong's eyes narrowed, "Guan Yu actually dares to seize this opportunity?" Isn't he afraid to bear the disadvantage of attacking the camp?

Now the partial divisions I sent out to burn and loot are indeed unable to return to defense, and our army's strength is indeed in a weak position. But how can the number of troops make up for the disadvantage of attacking the camp? The whole army is fighting! Drum cheers! Command the left and right battalions to come and reinforce quickly! ”

Guan Yu's attack was a dignified attack of Great White Heaven, so there was no possibility of a sneak attack.

Guan Yu ran for more than ten miles, and when he reached the outside of the Zhenrong camp, the main camp of the Chinese army in Zhenrong had already made all the defensive preparations and was ready for battle.

The left and right battalions have also been notified that reinforcements may be sent at any time, and at most more than a quarter of an hour later, the left and right battalions will be able to arrive.

This is something that Zhen Rong knows, and Guan Yu actually knows it.

Guan Yu's army on the opposite side was full of 8,000 people - Guan Yu's total strength in Chaisang, a total of 12,000, 2,000 were taken away by Gan Ning, and he went to the mountains to be bait, and he still needed to leave 2,000 to defend the city, so he only sent these 8,000 attack camps.

After Guan Yu galloped in place, he asked the soldiers to rest for a while, take a few minutes to regroup, and then decisively ordered:

"Don't miss the opportunity, at most a quarter of an hour, the left and right battalions of Zhenrong will come to reinforce it. Within a quarter of an hour, we will break through the walls of the Chinese army camp and cause the collapse of the army. The crossbowmen stepped forward to suppress! Scratch the hook hand and break the antlers to resist the horse, and the whole army will charge with me! ”
