One person, one horse, one thousand miles, four days can be reached. Three people can reach it in five days. A thousand people have no horses and a thousand miles, and there are no mountains and rivers for ten days.

Experience is a very important thing, Xiao Song, who led the troops for the first time, was not as smooth as he imagined, the speed of the five thousand foot soldiers was so slow that his scalp was numb, and it had been ten days since he came out of Nanchang City, but now he was stuck between Nanchang and Changsha, and he couldn't advance or retreat for seven hundred and twenty miles.

He's going to cross the river, big guy. In order to save time, Xiao Song could only think of asking the surrounding fishermen and boatmen to help with the ferry.

Question: How long does it take for a boat to make a round trip in a quarter of an hour, and for a boat to carry eight people, and fifty boats to carry five thousand two hundred and twenty-seven men, one white seventy mules, and forty-five horses?

It's good, isn't it, so the delay is two days, and most of it has just passed here, and then the mid-waist troops are fucking there...... The two sections of people actually buried the pot together by the river and cooked together.

The mid-waist troops were slow troops, and they did not need to march in a hurry, but only needed to be drafted along the way, transport goods to and from Nanchang and between the troops, and pacify the local population.

In this way, they still caught up with the vanguard......

"Sad."

Song Beiyun squatted next to the tributaries of the Xiangjiang River and worried, this is still a small river, if it touches a big river, the detour will not only delay the time but also give people a chance to make dumplings.

"Yun Shuai, eat something."

Someone brought a bowl of rice paste, which contained some minced meat and some bitter salt, but there were these things to eat on the way to the march, which was already of the highest standard, and it was thanks to the continuous delivery of grain and grass from Jiangxi Farm.

"Just this big river, let a whole army get stuck here for two days, two days!" Song Beiyun squatted in that tone full of grievances: "It's my fault, I didn't expect to cross the river." ”

"Yun Shuai is also the first time to take charge of the army, it is not easy to have such ability, along the way, we waited for Yun Shuai's orders to execute, and now the team has expanded to more than 30,000 people."

"Most of them are people, it's useless, you can't let them be cannon fodder." Song Beiyun sighed speechlessly: "I can only get hard." ”

Now everyone calls him Yun Shuai, this title is a bit likeable, but the more this is the case, the more pressure he Xiao Song has in his heart, after all, the word "handsome" is not to praise his appearance but to recognize his status and ability.

If he can't bring these soldiers back completely, he won't be able to keep them in order, and he will have some kind of war trauma stress syndrome.

So he has been very busy and tired these days, but in this state now, there is really nothing to do, just take a break and recuperate.

"After crossing the river, you can get to Changsha City in less than two days, if Changsha City does not open the city gate, Yun Shuai has thought about how to do it?"

"If he doesn't open the door, I will turn around and leave, now this Changsha city is like a fish in the throat, no wonder what the hell Changsha, Nanchang, Xiangyang, Wuchang These ghost places are all important towns in Junzhou, this is your mother...... Ah! Song Beiyun looked at the mountains in front of him, and rubbed his face painfully: "It's too difficult." ”

He used to always remember that the transportation in Changsha was quite convenient, but in the past two days, he realized that his thinking was solidified, and he thought that the transportation convenience was provincial highways, national highways, high-speed railways, airplanes, highways and the Yangtze River Bridge, but these things are not available now.

Nothing! The official road is not a river, and the only bridge in this area was demolished a year ago because of repairs.

Just as Song Beiyun was watching dozens of palm-sized boats shuttling across the river, a soldier suddenly stepped forward and said, "Yun Shuai, there is a craftsman in the middle waist, he said that he has a way to let the army pass in two days." ”

"Huh?" Song Beiyun immediately got up: "Hurry up, please come!" ”

Soon, a black and thin man in his forties and fifties was brought to Song Beiyun, he was still a little timid when he saw Song Beiyun, he couldn't speak well, his eyes were still flashing, his hands kept pulling his pants, and he looked quite nervous.

"Don't be nervous, big brother...... Uncle, I'll call you uncle. Song Beiyun pointed to the hundred-meter-long river: "If you have a way, hurry up." ”

The craftsman saw Song Beiyun's appearance, but he became even more anxious, and he didn't let out a fart for a long time.

"Fifty times!" Song Beiyun stretched out a hand: "You solve it, give you fifty times, I will speak!" ”

Fifty times, you can't make so much money in a year, the craftsman suddenly smiled, and he began to talk with a gesture, to the effect that he was originally a leathermaker by the Yellow River, and wanted to cross such a small river on the side of the Yellow River, and it was impossible to build a bridge, because every year the Yellow River flooded, and the bridge was gone.

Therefore, the local people came up with a way, that is, each village will have a set of pontoon bridges, which is tied to the sheepskin of the drum with the wooden rows, and one by one can easily cross the bridge, only need to drive a few solid wooden stakes on both sides of the bank, hang four ropes, and the pontoon bridge will become. In addition, when not in use, the sheepskin can be aerated and dried to be reused for the next river crossing.

"Mother...... You're such a genius. ”

Song Beiyun slapped his thigh hard, although he is a traverser, he doesn't have so much life experience in the world, this method has been used from ancient times to the present, but Song Beiyun, who is used to crossing the bridge by car, where can he understand the usefulness of this thing, not to mention that he has not lived on the edge of the Yellow River, let alone pay special attention to this thing.

"Come on, get a fifty guan for this master, and then let him take you to build a pontoon bridge, be quick!"

There were a lot of sheepskins, and the craftsmanship was not a difficult thing, so the cobbler soon led two hundred or so people to make a set of pontoon bridges that could cross the river, and the ropes were tied to the opposite bank, and a little pontoon was led over, and then fixed, and finally in the evening the pontoon was formed.

"Alright, don't move, I'll be the first to go!"

Song Beiyun was the first to jump down and step on the pontoon, although it did feel a little sinking, it was quite stable, and the design of the pontoon bridge was quite good, that is, no matter what, one of the rafts could only step on the weight of two people at most, and the weight of two people would not make the raft overturn.

As for sheepskins, there are a lot of them...... At this time, the results of the logistics troops in these days were presented, and the livestock collected from the villagers' homes were kept in their skins after eating the meat.

A team of tens of thousands of people, with a bridge, quickly crossed the river, and he immediately regrouped, and the sharp-knife troops did not have time to rest, and immediately set off with torches to go as far as they could.

And after the incident of this pontoon bridge, Song Beiyun had a deeper understanding of the troubles in leading the troops to fight, and also realized how valuable the life experience accumulated by the ancestors for thousands of years was.

However, this can't be learned in the book, because the status of the craftsman in both the art of war and the history books is very low, and it is rarely mentioned, so this kind of situation is usually his mother's four words "meet the river, the degree" of the "degree" or the fake word.

"Life is a science, you have to study hard." Song Beiyun opened the small book and recorded today's fulfilling day, recording the entire production method of the pontoon, from drying, tanning, gluing and other processes, and even the extremely viscous fish gelatin formula to record it.

What is this? This is the treasure of the history of the Chinese nation, even if it is useless and eliminated in the future, you can also educate your children and grandchildren to say, "At that time, China was definitely sitting on the top of the world's scientific and technological mountain, but you are still superstitious about the European Middle Ages."

After the march reached about ten miles, because the mountain road was really difficult to walk, Xiao Song did not let the army continue to advance, but camped and prepared to rest.

As the manager, he has his own independent tent, but this tent is quite simple, more people just sleep on the ground together, and warm each other with body temperature to keep out the cold.

The conditions cannot be said to be not difficult, but Song Beiyun really has no way now, but he has already written down the future work arrangements in his booklet, that is, to form the logistics support theory into a system.

Logistics is definitely not only about food, grass and weapons, but also about all aspects of soldiers, and this must not be sloppy.

After all the spring cold was expected, Song Beiyun didn't even bother to wash up, so he started marching again, Qiaoyun wore out his shoes, and he also wore straw sandals with the soldiers, and blood blisters also appeared on his feet, but who the hell cares about this at this time.

After two days of delay, he had to use the fastest time to recover what he had lost.

Walking to the village on the road, Song Beiyun will send people in to carry out some simple supplies, mainly water and some medicines, but they will give money, this rule is his iron order, the biggest title sponsor of this rebellion, Jiangxi Xu family, once sponsored enough military expenses to support them to fight for half a year.

Song Beiyun felt that the old man was very angry, probably part of the plan to disperse the family wealth, but at the same time, his vision was still limited by the times, because the more he dispersed like this, it would not be long before the rebellion ended, and he would come back again, and he might come faster and more.

The villages in the land of fish and rice are usually not too bad, Song Beiyun and they can usually buy good things at the market guide price, and even after the news spreads, there will be many people along the way who follow the army all the way to sell their goods.

Song Beiyun privately bought a big Wang Ba with a full weight of three catties and two taels and stewed it......

But it's not delicious, there is no seasoning, and the earthy smell is heavy......

And after a day's rapid march, in the evening, according to the local villagers, the city of Changsha was already close at hand, about 120 miles away.

Sixty kilometers, that is, the distance of a day's rapid march, you will be able to see the location of Changsha City by this time tomorrow.

Just as he was expecting it, news suddenly came from the Tanma in front of him, saying that a large army was approaching this way.
