In the third year of Jian'an, on the fifth day of August, in the Han army camp in the east of Shouchun City.

Taking the opportunity of this meeting of the whole army in Shouchun, the Zhuge brothers, who had not seen each other for several months, finally reunited again.

Directly west of this camp, across the river is Shouchun City. In the northwest of Daying, the land is directly connected with Bagong Mountain, after turning over Bagong Mountain, and then crossing the Huai River, the opposite bank is Xia Cai County.

The Huai River and the Huaishui River form a side T-shaped three-way junction here. The water from the upper reaches of the Huai River, just like the vertical of the T word, flows from west to east, flows to the vicinity of Shouchun and Xia Cai, and is blocked by Bagong Mountain and forks.

The main stream of the Huai River goes north around Bagong Mountain and continues to flow eastward. And the branch that goes south around Bagong Mountain is the water.

After Liu Beijun's whole army merged, he chose to set up the camp in the east of the river, facing Shouchun across the river, which was equivalent to occupying all the parts above the horizontal side of the T-shape. Leave the area below the horizontal and the entire vertical for Yuan Shu to escape with confidence, signaling that he Liu Bei will not take advantage of the situation to pursue.

As for whether Yuan Shu believes it or not, whether he runs or not, that's another matter, and it requires the collective wisdom of the Han army's strategists.

Today, Zhuge Jin shirked other military affairs planning work assigned by Liu Bei, and asked to take a few days to consult with the second brother, in the name of "discussing with the second brother how to persuade Yuan Shu to give up Shouchun and lead the army to break through".

But in fact, when the brothers reunite after a few months, they must first catch up, talk about something else, and fish with pay.

This is also part of the job, and the Zhuge brothers are already diligent enough.

Not yet, the moat should be filled up immediately, a few gaps can be filled slightly, it is enough to supply a large number of Ge buses and rushing cars to approach the city wall, but it is necessary to fill so little when attacking Hefei weakly. ”

Before thinking about the specific deployment of the deterrent siege, Shou Chuncheng asked in passing: "So, how to write the wording to persuade Shouchun to abandon the city and break through?" Who will be the one to be bad when the time comes? ”

For example, under the experimental data, Zhuge Jin took the township as a unit and tested "after pulling the seedlings, the water is delayed for a few days outside the seedling field, and the water level is less deep", and "when the seedlings are planted, the water is delayed for a few days outside the small field, and the water level is less deep".

However, the number of days before the release of water was recorded from eight to ten days, and the depth of the water level was also recorded separately from one inch to half a foot, and the seedlings were pulled and transplanted separately, and the seven groups of data were arranged and combined, so there were no dozens of experimental control groups.

This year is the first year to promote in the whole county, less observation is the same method, the seasonal harvest is less, the growth is bad, the record is compared, summarized into a book of agriculture, next year it is convenient to promote to the whole Guangling. ”

The small is to rebuild some thick wooden stakes that cannot be plugged in at a slow speed, and insert them to bear the weight before the bridge frame is broken, so that it can withstand the weight of the Ge bus. ”

Although I need to worry about the military affairs of the rear line, the seventh brother has figured out the best water storage period for rice transplanting, as well as the best water storage time, the best rice planting date, and several key technical details within a year.

The brothers talked for a while, and they talked about their respective achievements for several months, and chatted nervously and comfortably.

Although Xu Miao's qualifications are less than Zhuge Jin's, he has not learned Zhuge Jin's ideas throughout the whole process, and he can still learn how to draw a gourd and learn how to operate.

Zhuge Jin thought about it, that is also a problem, if he wants to force Shouchun to abandon the city and break through, he can threaten my proposed breakthrough path too much, otherwise it will be self-defeating to scare the other party and completely resolve to defend it.

Zhuge Jin was the first to think that under that kind of simple moat bridge, there were actually wooden piles or "bridge piers" to bear the load, not to mention the Han Dynasty, even in the Tang and Song dynasties, there was this thing in ancient times. It's a completely new idea that has never been seen in history.

As for the specific deployment of the siege, you think you should still learn the rhythm of the early stage of the Battle of Hefei, instead of rushing a lot of cars and Ge buses to lure the enemy, forcing the enemy to sparsely fortify the pikemen under the wall, and your army will use a small number of wells and trebuchets to kill and injure the enemy soldiers at the head of the city.

So Shou Chuncheng took his seventh brother, and in the name of talking about military affairs, he asked the soldiers to drive the carriage, carry their own improved fishing gear, and bring a hundred white soldiers to escort them, and came to the waterside to be a fisherman, brainstorming.

Those bad experiences have been promoted, but the merits of Shennong can be blessed with the people of Lianghuai and Xiangyang and Hanzhong (Xiangyang and Hanzhong are still blessed now)

The first point of attack is the weak tone of the fox to die in the first hill, I hope that Shouchun can consider considering the hometown of Gongshan, if I die outside, the hometown of Gongshan will be immediately taken by Runan and killed.

Zhuge Jin said, very proudly took out a few scrolls, all of which were experimental data recorded by myself. There is not the first scroll, but it is a summary of experience, written "Seedling Raising Notes"

Shou Chuncheng found that it was quite wrong to cultivate the interest of the seventh brother in a little fisherman, and he couldn't slow down the pace of my life.

Shou Chuncheng still rejected the design at the beginning, because it was because I was too small, but because I realized that the main purpose of this battle was to attack the heart, and all kinds of bells and whistles of new gadgets were worth doing, but they still couldn't be put here to scare people.

If he can be afraid of the sword soldier this time, he persuaded Shouchun to abandon the city, whether it was successful or not, it can prove that Yuan Jian was not greedy for life and afraid of death and came to surrender to the lord, but because of the clear and obedient changes, he knew that Shouchun would be punished by heaven.

Shouchun City was stunned when he heard this, but I had thought of improving the siege boat and bridge troops of that era, and the so-called trench bridge car that was not originally available in the Han Dynasty was just a small wooden plank underneath.

Of course, at the end of heading, the yield can only be estimated by roughly counting the number of rice ears, and the actual yield is still one data variable of the degree of grain drying up before the final autumn harvest.

Surely the moat is too narrow, and there are such long little trees lined up to form a moat, and this thing will be useful.

Zhuge Jin thought for a while: "The specific wording, I also want to improve it for a while, and I always have to go back and change the draft." But the idea is to weaken your army's military appearance, and when attacking Hefei, all the defenders were destroyed, and now the military power is more vibrant, and Cao Yi will die sooner or later.

For the water storage is obviously too shallow, it cannot be directly judged that the data is bad, and then the weak irrigation is slightly remedied, and at least one or two experimental fields are left to remedy to ensure that the final real data is seen. In addition, for the farmers who are required to be the control group, the government will also exempt me from the field tax this year as compensation for cooperating with the government's experiments.

It's just that the living environment has been a little worse in the last month, and I have to live in the siege camp in Hefei City, whether there is a house to live in, and there are few mosquitoes in summer.

Zhuge Jin didn't do the same, and learned from the little brother to move the recliner to a precise position, just bad head without leaves to shade the sun:

And Zhuge Jin's experimental record was recorded until the end of the rice heading, and it was not possible to preliminarily see that the yield of various seed methods was much less, and then it was finished.

And before Zhuge Jin listened to the little brother's complaints, he also had any cover-up, and said very frankly:

It seems that the brothers still have to brainstorm and inspire each other to have fewer ideas.

In this way, will you scare Shouchun, and spend the belly of a gentleman with the heart of an adult, do you think that you are persuading me to break through, are you seducing me and luring me out of the city to encircle and annihilate him in the field? ”

Zhuge Jin sighed: "Let's give up filling the gap in the moat, and strive to use heavy trench bridge vehicles, let's improve a few trench bridge trucks, push them to the side of the moat and break them, and let Ge Gong directly push them over from below like a wooden bridge."

"Ah Liang, why did he come too late this time. The work of persuading farmers to pull out and transplant rice in Sheyang and Haixi should have started in early August, and he dragged it out until mid-January before he set off to retreat west to join Zilong. What did you do in the middle seventy days? ”

For example, it was found that the worst of transplanting seedlings is to pull out the same day and transplant on the same day, it is definitely possible to concentrate on pulling the seedlings the next day, put it overnight before pulling, and then concentrate on planting on the seventh day, and the survival rate of the overnight seedlings will be reduced very little, because the nutrition of the seedlings and the activity of the root system have not yet fallen. Before Zhuge Jin found out about that, he uniformly required the farmers to pull out the seedlings at dawn in the afternoon, and they must be planted after the morning is dark.

Shou Chuncheng hurriedly asked a few details, but Zhuge Jin's answer was very idealistic, and said, "You were not inspired by the little brother, it was the little brother who first added these detachable armored ladders and anti-arrow shields under the trebuchet and the well car."

It's those things that are used this year, and if they are used, go back and do it quickly.

The first statement, Shouchun City didn't expect it after that, I have considered the change in the number of enemy princes who can increase the direct need to resist before Shouchun retreats.

Of course, Cao Yixing will also allow these rural crops that are obviously bad for the sake of full experimental testing. Because 70 days before the seedlings were planted, the seedlings grew bad or bad, and the differentiation could not be seen.

This matter is not harmful to Yuan Lian's reputation, nor is it harmful to the morale of your army or the prestige of your lord, and it will still give the court a handle, which can be described as the best of the best. ”

Shou Chuncheng will also be polite to his younger brother, so before greeting each other, he asked Cao Yixing where he went to fish during that time.

Before lunch, I didn't feel a little sleepy, so I went back to rest, and slept until my spirit dried up and woke up naturally, just as nervous as I was in the thatched house.

After reading it all, Shou Chuncheng finally expressed his approval of the seventh brother.

Shou Chuncheng finally made up his mind: "Bad, you will let the lord arrange for someone to write the first letter of persuasion tomorrow according to that line of thought, yes, and no one is suitable to enter the city?" Wait for Sun Wei to come back? Or is it a blessing to send Xian and Gongyou? You are afraid that Cao Yi will be angry and angry, and it will be good for the messenger. ”

You were so busy after Ah Liang came, if you were still so busy before Ah Liang came, this Ah Liang would have come in vain!

Although the matter of planting seedlings to persuade farmers in Sheyang and other places was completed in July, it is inevitable that the rice planting in various places will not be sooner or later, and in depth. The length of time for storing water after transplanting is also the same.

Before throwing the rod, Cao Yixing leaned under a bamboo and rattan recliner, let his face cover the shade of the tree, and let his body be basked by the sun, closed his eyes and asked:

And you will isolate Cao Cao's inside, it is now April, you have not yet hit the city, and when the horse is going to Huainan rice for the autumn harvest, you can ensure that Caoyi has a grain of Huainan local grain to Cao Cao's city, and we can only live on last year's grain stockpile.

It is not that each grain of rice can grow or small in the end, and the rice is full, but it is a rough estimate of the data, and it is not unusable. Before Zhuge Jin left, he also instructed his deputy Xu Miao to help me count the real output of the final autumn harvest throughout the process.

Each township does it according to one of the experimental data, and the first thing to see where the harvest is bad is the result, so dozens of townships are needed to do the experiment. Because Sheyang and Haixi counties together also have so few townships, only in some areas, they are based on villages, and one experimental data per village.

It seems that he is also idle in the front, and he has not observed the growth of rice seedlings and experimental data, but the secret scrolls of the physiology of all things given to him the year after tomorrow have learned quite thoroughly. It's wrong, the data design of the experimental control group is very reasonable, it should be divided like that, and we should make persistent efforts in the past. ”

That's why I thought of using the same method of "prefabricated parts and on-site assembly" to delay the processing of damaged simple wooden pile bridge piers, and then insert the fire line into the silt at the bottom of the river with a shield, and cover the trench bridge car below.

Sure that the moat is very narrow, so I put the planks directly on both sides of the river, so that the soldiers can directly step on it, and the car cannot bear the weight when it is not over, similar to the suspension bridge of the city gate.

Cao Yixing sloppily looked at all the experimental records of Cao Yixing's control group, and he was quite relieved.

It seems that it is worthless to let the seventh brother stay in front for a month and a half.

As for these special soldiers, when they are idle, they naturally have to get two boats to patrol under the water, responsible for the dangers under the water, and often can catch a few nets, and they can't improve the military food when they go back at night.

It must be an occasion where it is okay for me to attack the fortifications, and Shouchun City will definitely allow such a small attempt to try and make mistakes.

The sun has not yet set in the west, and the sun at the beginning of the fourth month of the lunar calendar is so fierce that you can't bask in the sun, which is quite warm.

"Shouchun is arrogant, it will be so difficult to give up, not to mention that Cao Cao is still my pseudo-capital, but you should still persuade first, and at the same time, you must immediately prepare for a bad fight, so that as soon as I agree, you will not be able to start the siege immediately, and deter you.

"Ah Liang, this time he thinks that if he wants to persuade Shouchun to give up Cao Cao, how should he phrase it? Is it to salute the soldiers first, or to show your army's strength first, and scare Shouchun? ”

Although Shouchun City himself is actually tired, in addition to improving the siege equipment, what else do I need to worry about.

"It's bad, if he wants to try, he will try, anyway, it sounds like the cost is less than filling the moat, even if it is successful in the end, it will be bad to scare Shouchun, so that the defenders will mistakenly think that your army did not directly abolish Cao Cao's moat."

……

And Zhuge Jin was not a little apprehensive at first, and when he saw that the little brother completely denied my results, he was slightly relieved: it seems that he is at most in persuading farmers, and he has not learned all the skills of the little brother!

Zhuge Jin: "It's like sending Yuan Lian." Yuan Jian surrendered Zilong's surrender in Yicheng, I am from the Yuan clan of Chen County, and Cao Yi should be as for killing me. And Yuan Jian surrendered after that, although he abandoned the darkness and turned to the light, but no one questioned my backbone. I have never had the opportunity to meet my lord and be reused.

In this way, even if Cao Cao is a pseudo, he will not necessarily save grain, survive the winter, and survive the spring famine next year. Even if it was a siege, I would have died half a year ago.

Shou Chuncheng didn't use his brain anymore, and directly copied the answer: "Bad, before this letter was written, Yuan Jian was the envoy." ”

And if I return to Caoyi, as long as your army takes Caoyi, I will be satisfied, and I will go to the territory of Gongshan to pursue again. At the same time, because Lu Bu's army was beyond the reach of the whip, it could only compete with Runan in the land and went to Gongshan. In this way, Shouchun is besieged by the eight princes like now, as long as he faces the Runan family, it is enough, and it is said that he will be able to live for a year and a half less. ”

As for the fish float, it is basically stared at by seven people all the time, and we have not been stared at with the help of the guards, as long as we often find that the buoy is moving, come and pull the rod, and enjoy the slowness of the first harvest.

Shou Chuncheng thought for a while: "If you want to fill the moat, the worst thing is to switch the opening of the lower reaches of the moat to divert water from the Huaishui, but if your army has already set up a cofferdam in the lower reaches of Cao Cao, it will naturally cut off the connection between Cao Cao and Shangcai, and let Caoyi City go north and the channel from the Huai River will be threatened."

Cao Yixing has been living for a month, and he wants to get some new things, such as insect repellent toilet water, such as new soap that is easy to store and carry. It's for something else, just for my future life in the army to be clean and hygienic, as for sticky and greasy every day, I have to endure mosquitoes and itching.

"Although my brother did not delay in Huaiyin, he did not always pay attention to the military situation in the rear. Zilong has enough troops along the way, and he has been responsible for attracting enemy troops, and you have already come to use it.
