"Before I talk about the military strength of our Reconstruction Society, I would like to introduce you to one person. Amu, come in. ”

With Guan Yi's call, Wumeng Amu, the eagle craftsman of the former Dong Ju family, walked in with his head down.

"Ladies and gentlemen, this is a Yi man from Hanjia County, whose surname is Wumeng, and his name is Amu. Good at raising eagles. Jing Yao entered my scene in the second year. After two and a half years of hard work, he and his father trained five warhawks that could hover the battlefield and use the direction and number of circles in the air to deliver messages to the falconry on the ground! ”

"Good!" The first to stand up and applaud was Liao Yong, who was seventy years old this year, and he was so excited that his beard was about to fly: "Jun Hou, this is a sharp weapon on the battlefield!" In this way, the number of enemy troops and every move will not be in my eyes. ”

"Hehehe, don't be too happy. After all, this war eagle is a beast, how can it convey too detailed information. But with this thing, it will be very difficult for the enemy to ambush us. ”

"Oh, Junhou, even if this is the case, it is against the sky."

"Hehehe, Uncle Yong sit down for a while." Guan Yi waved his hand: "Compared with the war eagle, I am even happier that this father and son have also cultivated a hundred carrier pigeons for my Fuxing Society that can transmit messages thousands of miles!" ”

"Ah???!!!h

Why can you all put an egg in your mouth? Oh, by the way, although the use of carrier pigeons to send messages has been around since ancient Egypt. However, the Chinese flying pigeon biography originated in the Sui and Tang dynasties. People of this era did not know that pigeons could transmit messages.

"Well, this summer, we've already done experiments between CD and Fuling. 10 pigeons were released from CD, and all of them successfully arrived in Fuling County. The fastest took nearly two days, and the slowest took only three and a half days......"

The people below are still in a stupid state......

So next, Benhou is ready to start setting up pigeon lofts in CD, Jiangyang and Fuling. Pigeons can be used in all three places to transmit messages. However, this matter is an epoch-making militaristic weapon, so please be sure to keep it a secret. ”

After Guan Yi finished speaking, everyone finally reacted. Then, in an instant, Umeng Amu was drowned in everyone's saliva.

"How much can this pigeon carry at one time?"

"Is it possible to achieve direct access from Nanzhong to Hanzhong?"

"What if we set up a pigeon loft in Pseudo-Wei and Dongwu?"

……

"Okay, good!" Looking at the chaotic scene, Guan Yi also had to stand up and press down with his hands: "Okay, okay, about the question of carrier pigeons, you can go to Amu and ask yourself after the meeting ends." Ben Hou will give you the bottom first. The cultivation of carrier pigeons is quite time-consuming and labor-intensive, and it has taken us more than two years to realize the communication of CD and Fuling, and I am ready to add Jiangyang in the next step. After that, if it goes well, we will consider Nanzhong and Hanzhong. In short, gradually push it out, and make sure that within three years, the carrier pigeons of the Fuxing Society will be covered in the existing territory of Dahan! ”

"Taishou is really a celestial!"

"Hey, brother, how come your surprise never stops. Forget it, forget it, I don't ......wonder if you summoned the meteorite rain one day."

"Nonsense, being a brother is not a demon like Zhang Jiao...... Well, Amu, you step aside. Guys, let's get down to business. ”

After Amu retreated, Guan Yi beckoned his family general to bring in a small topographic map of Yongliang Yibei.

"According to my many correspondence with the general in the past two years, the analysis of Yongbo, Gaizhi and others, as well as the various information from the Mijia merchants whose trade routes are all over the world. According to the comprehensive analysis, if in the last two or three years, on the premise of ensuring that the front lines of Jingzhou and Yangzhou and the forces of the Youhe defense against foreign races are not excessively weakened, the puppet Wei can send about 300,000 troops to launch an attack on our Han Dynasty! ”

Seeing that although everyone frowned, but no one jumped up in amazement, Guan Yi nodded secretly, and then continued: "Although theoretically pseudo-Wei can send 300,000 troops out, in practice this is impossible, because ......"

Guan Yi pointed the wooden stick in his hand to the majestic mountain range on the map between the Guanzhong Plain and the Hanzhong Basin: "Because of the existence of the Qinling Mountains, it is a trivial matter that it is very difficult for a large-scale army to march, and the most critical problem is that the grain is inconvenient, if the pseudo-Wei really uses 300,000 troops to press it together, and we don't need to fight, this logistical pressure will crush them!" ”

"According to the many correspondence between Ben Hou and the general, as well as interviews with a number of officials in charge of logistics and transportation when they participated in the Northern Expedition in the past, the following data were roughly obtained: Ten stone of grain was transported from CD or Ba County, because it was a plain terrain or could rely on the Jialing River for water transportation, so the loss when it arrived at Baishui Pass was relatively small, and probably only one stone would be consumed. But from the Baishui Pass, it is necessary to cross the Micang Mountain, and after crossing the Micang Mountain to reach the Hanzhong Basin, there are only six stones left of the ten stones of grain...... If our army wants to go on a northern expedition, it will either start from Hanzhong County and disperse the pass to attack martial arts. Either start from Wudu County, bypass Qishan, and enter Longxi. No matter which line you take, you have to cross the Qinling Mountains, and after our army crosses the Qinling Mountains, the six stones of grain will become less than three stones...... Basically, due to the limitations of the terrain, if our army wants to go on a northern expedition, before meeting the enemy, our army's food has been consumed seventy and a half times - it is precisely because of this that whether it is the former prime minister or the current general, its northern expedition offensive cannot last, and if the puppet Wei cannot defeat us in the field battle, he only needs to guard the various strongholds to force our army to retreat with all food......"

Speaking of which, Guan Yi is also very helpless in his heart, Shu Dao is difficult. Not to mention this era, even in the 20th century, the country built a Baocheng railway, which was also built with the help of the whole country for four years - and most of the sections were only single lines!

"It is already extremely difficult for our army to transship grain for the Northern Expedition, and this pseudo-Wei will attack me, and we will have to face the same problem. According to the general submitted to His Majesty last year the plan for the replacement of the defense of Hanzhong, our Han began to abandon the southern end of each valley mouth this year, and shrank into the various strongholds in the Hanzhong Basin on the whole line. I strongly disagree with this approach. But it should be noted that if the puppet Wei wants to attack me, he must first cross the Qinling Mountains. On this journey, the loss of grain is at least 30%! ”

"After entering the Hanzhong Basin, our army will inevitably implement the clearing of the strong walls, so that the enemy army will have no food to obtain, so the enemy's military food loss will not be reduced because of entering the basin...... If the enemy army breaks through Yang'an Pass, it will need to cross the Micang Mountain, and the loss of grain will increase greatly......"

"Based on the doubling of the loss of food during the war, a soldier needs at least two stone rations per month, and a horse needs at least three stone of food per month. If the puppet Wei launched 300,000 soldiers and 50,000 war horses to attack...... The amount of grain consumed on the front line in a month is as high as 750,000 stone of grain...... According to the calculation of six to seventy percent of the losses along the way, then in order to ensure that the soldiers on the front line are fed, the puppet Wei needs to transport 2.5 million stone of grain to the front line every month. Of course, the national strength of the puppet Wei is much stronger than that of our Han Dynasty, and tens of millions of stones of grain can be taken out through gritted teeth, but this is not the key to the problem. ”

"The crux of the matter is, how many people will be needed to transport these 2.5 million stone grain across the Qinling Mountains and Micang Mountain? If there are more people, will the loss along the way be further increased? After the loss increases, will we increase the number of people? The calculations will never end in this way......"

"Moreover, the road between Qinling and Micang Mountain is not easy to walk, and many places are wall-hung plank roads with a width of less than three feet. Such a road, on the one hand, the roadbed is not load-bearing, and it cannot carry too much weight - the transportation capacity of grain trucks will be greatly limited. On the other hand, the speed of transportation will slow down significantly with the increase of the number of grain transportation teams, which further increases the loss ......"

"Therefore, as long as the pseudo-Wei family is not an idiot, he will not press 300,000 at a time, and if he does that, he will collapse first due to logistical reasons. Therefore, what we can determine after careful calculation is that when the puppet Wei comes to attack our Han Dynasty, it can only invest 150,000 to 200,000 troops at a time at most. More than it gains. ”

After listening to Guan Yi's analysis, everyone nodded in agreement with a heavy heart.

"After clarifying the scale of the enemy's troops, we basically have a strategy for how to deal with it."
