He was betrayed at the beginning, from a cake seller to a wealthy person

Lu Yan prepared a lot of things. In addition to several large bags of necessary seasoning powder, she also brought several sacks of seeds.

Mrs. Xu prepared five sets of autumn and winter clothes for the two of them, two sets of late autumn clothes and three sets of winter clothes. Liaozhou is in the northernmost part of Dali, and the capital is in the Central Plains region. The further north you go, the cooler the temperature becomes. Moreover, it takes two months to walk, and it is already winter when you reach Liaozhou.

Mrs. Xu was afraid that the two of them would freeze, so she prepared handbooks and scarves. Boss Lu also made a wooden barrel for the fire and brought charcoal. Inspired by the insulated bucket that Lu Yan used to set up a stall, they put their hands and feet into the bucket to keep warm when they got cold.

Beidi is the only place in the country where live cattle can be slaughtered. Lu Yan also prepared a lot of things to exchange for cattle there. Even if she couldn't bring the meat back, she would directly refine the butter and make beef jerky. Lu Yan asked Xu to make a lot of embroidered handkerchiefs and purses, and planned to bring them over in exchange for things.

I heard from He Yue that Beidi has no embroidery skills, not even embroidery needles. The common ones are large and thick needles like sewing quilts. Beidi's sewing technology is completely functional and has no ornamental value. But then again, Beidi has surrendered now, and there is no need to fight or anything. A noble woman has nothing to do, why not dress up?

Some have piled up a carriage.

Seeing the two people acting like they were moving, the family dog ​​also came out to see them off. Those cats couldn't sit around during the day and visited the house every day. Only the cow cats stayed at home from time to time. Yinzi and Xiaobai also went out for a run, but they came back after two laps. They stayed at home most of the time, and curiously came together when they heard anything. Come and see.

Lu Yan has been busy for the past few months since she came to the capital, and she didn't pay much attention to playing with cats and dogs. She only feeds them every day. I was busy packing my things today, so I didn't care about it. I touched Yinzi's dog's head and let it play.

Lu Sheng remembered something interesting and told Lu Yan: "There were several times when I got up in the morning to go on duty, and Yin Zi followed me to play. All my colleagues in the Hanlin Academy knew him and knew that he was the dog of Lu Hanlin's family. ."

Lu Yan couldn't help but laugh: "This is called a dog relying on human power. Silver has changed from a village dog to a county dog ​​to a capital dog and then to Lu Hanlin's dog. His worth has doubled."

They both laughed.

On the day the prince set out, there were more than 500 carriages on the road, and Lu Yan was really shocked as far as the eye could see.

Lu Yan couldn't help but sigh: "How much food was transported?"

Lu Sheng laughed: "This is far from enough. We have to collect more grain when we get to the border town."

Lu Yan was surprised: "Huh?"

Lu Sheng settled an account for Lu Yan. After the surrender of Beidi, the Northern Xinjiang Army withdrew a large number of troops, leaving 5,000 main troops to garrison Liaozhou. How much food does a five thousand army need?

Volume 86 of "Song Book" describes how much food an army had during the Northern and Southern Dynasties: "Twenty thousand soldiers, eating 480,000 dendrobium of rice per year." In the Song Dynasty, one dendrobium weighed sixty kilograms, and forty Eighty thousand dendrobium is nearly 30 million jins, 20,000 people eat 30 million jins a year, and 5,000 people eat almost 7.5 million jins a year.

This is food for a year. The Northern Xinjiang Army usually grows food, but in the end, a group of them cannot escape the fate of "getting up in the morning to clean up the wasteland and returning with hoeing," and then "the grass is full of beans and the seedlings are sparse." The food they harvest is not enough to last for a year. , at least one season's worth of food must be transported for them to fill up. In other words, it must be at least about two million kilograms.

In addition to military rations, the food and grass needed to be eaten by the people and horses on the road for the food transport team. The journey took two months, so the food transported was increased by half, bringing three million catties. The weight of a carriage is about 1.5 tons (calculated based on the weight data of French army carriages during the Napoleonic period), which is kilograms. It would take two thousand carriages to transport all the grain. This time, only a quarter of the more than carriages were transported.

Lu Sheng: "But there is nothing we can do. This is the best we can do. The prince can't control it no matter how much."

Lu Yan was dumbfounded, and for the first time she had a concrete impression of the size of an army. There were only 500 carriages, but in Lu Yan's eyes, it was already a vast area with no end in sight. The army basically consisted of at least a thousand people, and it was not uncommon to have tens of thousands of people.

Lu Yan touched her chin: "Can you count the so-called one hundred thousand army?"

Lu Sheng: "Listen to them. When it comes to your 100,000 troops and my 200,000 troops, 20,000 is actually a lot. As long as the number of people exceeds 10,000, the visual effect is basically a sea of ​​​​people. There are no margins, and the other party won’t be able to tell if you over-report or under-report, but you can blow it hard and the bullshit won’t be broken.”

Lu Yan smiled and fell in the carriage.

The advantage of having more cars and horses is that the road is slower, and Lu Yan has more freedom. She can do her own thing along the way, and then she can catch up with the large army. After all, Lu Yan wants to travel along the road this time, so that she can discuss opening a trade route with Zhang Chang's family.
