Take Taobao to ancient times

"I made this according to your design drawings. I tried it myself and it works. You can take a look." The blacksmith pointed to the things in the middle yard.

"I'll give it a try." Lu Siyu sat up and rode around the yard.

That's right, this thing is nothing but a human-powered tricycle.

The existence of human-powered tricycles was particularly strong when New China was established and the power grid was insufficient. It was not until the introduction of effortless electric tricycles that human-powered tricycles gradually withdrew from the market.

In such an era, it is naturally impossible for Lu Siyu to use an electric tricycle, so he found a way to find the design drawing, thinking it would be difficult, but he did it unexpectedly.

Although it is rough in terms of speed, quality and appearance, it is indeed the prototype of a tricycle. As long as it has this one, it will be much easier to improve on this basis in the future.

In many dynasties, the trading of iron and salt was restricted. The former is the raw material for making weapons, while the latter is the necessities of life, so it is relatively difficult to buy. However, in this dynasty, as far as Lu Siyu knew, the limitations of iron were not Not big, as long as it is not purchased in large quantities, it will not be restricted.

"Uncle, what you did is very good. I still have two things, why don't you help me make them together." Lu Siyu took out two more blueprints.

The blacksmith took the blueprints and pointed to one of them: "Is this something similar to this?"

"Well, this is a bicycle, but you can't bring too many things." Lu Siyu suddenly began to trust the blacksmith's ability at this time.

"Can this thing work? Just two wheels?" the blacksmith wondered.

"Don't worry, it will be fine." Lu Siyu laughed loudly, "Then I'll go first and come back to pick it up in a few days."

"Row."

After getting the tricycle, Lu Siyu rode the tricycle directly out of the blacksmith shop, but did not go outside the city, but went to the county government office.

As soon as he arrived at the county government office, he saw Zhuang Jinhan's figure.

"Brother Zhuang."

"Brother Yu, why are you here?" Zhuang Jinhan was surprised and smiled, "This is the first time you have come to see me."

"Go to the Palace of Three Treasures for nothing," Lu Siyu said on his own initiative, "Brother Zhuang, are you interested in walking around with me?"

"Of course, what is this? I saw you used this to come here just now?" Zhuang Jinhan pointed at the tricycle.

"When you're outside the city, let Brother Zhuang try?" Lu Siyu chuckled.

"Row!"

The appearance of tricycles is actually a bit late. Bicycles and rickshaws should have appeared earlier. Many TV dramas in the Republic of China appeared more rickshaws, and tricycles are a combination of rickshaws and bicycles.

The means of transportation in this era were either horse carts, ox carts, or donkey carts.

Modern means of transportation are of course based on various gasoline vehicles and kerosene vehicles.

With Lu Siyu's ability, at most he would have people make bicycles and human-powered tricycles. Later, electric vehicles involved more profound technology, and needed electricity and oil power to drive, which was more complicated, so he had no choice but to ignore them for the time being.

Tricycles are simpler than bicycles because they do not involve balancing forces and are less prone to accidents even on uneven roads.

Once outside the city, Zhuang Jinhan tried riding a bicycle.

"It's a bit laborious, but it's a little more convenient than ox carts and horse carts. Are you planning to promote him?" Zhuang Jinhan asked immediately.

"Is it not possible?" Lu Siyu asked back, he could hear the disapproval in Zhuang Jinhan's words.

"Unless all the roads can be the same as the roads in the capital, if it is such a road, the metal wear will be serious, coupled with the limitation of raw materials, the price is too expensive, ordinary people can't afford it, and they will choose to use a horse-drawn carriage if they have a little money " Zhuang Jinhan explained.

"I see." Lu Siyu nodded, but he didn't feel much disappointed.

Zhuang Jinhan looked at him and wanted to comfort him: "You have a good idea, but..."

"You don't have to comfort me," Lu Siyu chuckled, "I can use it myself if I can't promote it, and I don't have to use it to make money."

"That's good, I thought..." Zhuang Jinhan whispered.

"What do you think? Do you think I'm thinking about making money all the time?" Lu Siyu smiled, "I'm just free, I have nothing to do anyway, and I have some spare money, so I just want to do some messy things to pass the time, by the way , do you have anything else to do later?"

"It's nothing, the county is very quiet recently." Zhuang Jinhan shook his head.

"In this case, you can take me back and exercise your body." Lu Siyu joked.

"Okay." With that said, Zhuang Jinhan started walking towards Lujia Village.

"Oh? I was just joking. Brother Zhuang, you are busy, so you don't need..." Lu Siyu said quickly, and was about to get up.

"Sit still, I'm speeding up." Zhuang Jinhan suddenly accelerated his riding speed.

Lu Siyu fell down on the chair in the car, sighed helplessly, it's all over now, he provoked him on his own initiative.

Sitting on the back seat of the tricycle, Lu Siyu rested his chin and began to think.

Where does industrialization start?

Food, clothing and housing.

Clothing, the textile industry, perhaps we should find a way to start with the textile industry.

Eat and clothe first, then consider housing, transportation and entertainment. Everything must be done step by step, and it cannot be done overnight.

Although Lu Siyu carried Taobao with him, the balance in it was limited, and some things he bought could not be used, so he couldn't do many things.

"How's the sweet potato situation?"

"Almost all the ones that have been handed out have sprouted, and they will be harvested in autumn. Many people are thanking the emperor, and all of this is because of you." Zhuang Jinhan said seriously, the people know the value of mu yield better than officials, So those who distributed sweet potatoes were very excited, just waiting for a bumper harvest this season.

"It has nothing to do with me, it's just paying the money and delivering the goods." Lu Siyu laughed.

"In any case, it's all your credit." Zhuang Jinhan still said seriously.

"That's my credit." Lu Siyu smiled and didn't argue with him.

Zhuang Jinhan rode a tricycle directly into the village, attracting the attention of many villagers along the way, but because the two didn't stop, the villagers couldn't ask.

When they arrived at Lu Siyu's house, the tricycle went straight into the yard, and then parked in the corner.

"Brother, you're back." Lu Siyun ran over.

"I'm here too, why don't you ask?" Zhuang Jinhan looked at him.

"Brother Zhuang is not a guest," Lu Siyun smiled, but took Lu Siyu's hand, "Brother, I already know how to recite all the ninety-nine multiplication tables, and I will recite them for you."

"Nine-Nine Multiplication Table, is it "Nine-Nine Multiplication Song Jue"?" Zhuang Jinhan asked curiously.

The ninety-nine multiplication table seems to be a modern thing in the eyes of many people. In fact, if we look carefully, we can find that in books such as "Xunzi", "Guanzi" and "Warring States Policy" such as " Sentences such as "three nine 27", "four eight 32", "six six 36", etc., it can be seen that the nine-nine multiplication table has been used in our country as early as the Spring and Autumn Period and the Warring States Period.

However, the nine-nine multiplication table at this time is not called the nine-nine multiplication table, but the nine-nine multiplication table. .

When Lu Siyu started to teach two children mathematics, he specially bought a set of elementary school mathematics textbooks on Taobao, which explained in detail, and he also found the existence of the nine-nine multiplication formula from the memory of the original owner.

"I changed it a little bit to make him memorize it faster." Lu Siyu is used to starting from one by one, so when teaching, he naturally started from one by one. Not only that, he also taught three different The way numbers are recorded.

Arabic numerals, simplified numerals and traditional numerals.

Reciting backwards or forwards, the gap is actually not that big. Zhuang Jinhan listened for a while, and couldn't help but said: "Yun Yun is really smart, you really don't consider letting him take the imperial examination?"

"He can figure it out for himself, he can do whatever he likes." Lu Siyu still hoped that the three children could go on according to their own ideas.

"What about you?" Zhuang Jinhan looked at Lu Siyu suddenly, "Didn't you say that you want to take the imperial examination, have you not worked hard recently?"

Lu Siyu froze for a moment, feeling a little guilty: "Ah..."

"Brother Yu, it was you who said you wanted to be a scholar. With your current state, it is absolutely impossible to be a scholar." Zhuang Jinhan looked serious.

At the beginning, Lu Siyu considered the matter of being a scholar, but because his parents passed away, according to the regulations, he had to observe mourning for three years, so he was not allowed to take the exam for three years. After a long time, he kind of forgot about it.

In his opinion, the difficulty of the exam for a scholar is no different from that of the college entrance examination, and he now regrets that he boasted about taking the exam for a scholar in Haikou.

"Brother Zhuang, don't worry, I won't give up my studies, I'll go buy books later." Lu Siyu immediately said, with Zhuang Jinhan's personality, if he said that he didn't want to be a scholar, he would definitely be bullied immediately, so he might as well give in.

Zhuang Jinhan's face softened slightly: "I have some books there, I'll bring them to you later."

"Okay." Lu Siyu nodded quickly.

For dinner, Lu Siyu made sweet potato flour, which was very delicious with some seasoning.

"This is a good thing." Zhuang Jinhan praised.

"Of course, ten catties of sweet potatoes yields only two catties of sweet potato flour. Wouldn't it be delicious?" Lu Siyu said, he just wanted this one bite, otherwise he wouldn't have worked so hard to make it.

"No wonder?" Zhuang Jinhan sighed, "Good things are always like this, it takes time and effort, and this sweet potato powder is not something ordinary people can afford."

"Why can't I afford it? When the production of sweet potatoes increases in the future, some people will definitely start thinking about disposing of the extra sweet potatoes. After making sweet potato flour, the surplus can be fed to pigs to ensure that those pigs will be fattened. Strong." Lu Siyu said, this is true, after all, sweet potatoes have a relatively high starch content, and as pig feed, it can indeed fatten the pigs.

"You, now everyone is still thinking about how to promote sweet potatoes across the country, and you have already started to think about the future. How did your brain grow?" Zhuang Jinhan looked at him and raised his hand to pat him on the head. , looking very helpless.

"Probably because I'm smarter." Lu Siyu spread his hands and said with a smile.

"Indeed, you are smarter than many people, and the one outside, I don't know what you think, how did you actually make it?" Zhuang Jinhan was talking about the tricycle.

"That's it. My brain must be better." Lu Siyu said with a smile, not afraid of Zhuang Jinhan's suspicion. The more calm he is, the less he will be suspected. On the contrary, if he is uneasy, he will be considered a guilty conscience.
