The wheelchair that Li An is experiencing is a new type of wheelchair tailored for Li Yi, the king of Xin'an, this wheelchair has one more structure to adjust the backrest than the previous wheelchair, and in addition, a mechanism that can be opened and a small platform are installed under the buttocks to facilitate the use of people with inconvenient legs and feet, which can be conveniently located directly on the wheelchair.

"You're doing a good job, but is this backrest sturdy enough to change around? Will it break? ”

Li An is most worried about safety now, after all, this wheelchair is to be handed over to Li Yi, the king of Xin'an, if the safety is not up to standard, and Li Yi is dropped, the consequences will not be good.

"Don't worry, we have tested it many times, and the three of us will not break when lying on it, and the safety issue is absolutely reliable."

Li An got up, carefully inspected the mechanism that changed the angle of the backrest, and shook it with his hand, feeling quite strong, as long as the wood itself has no quality problems, it should not break, and the safety performance is relatively reliable.

"Oh, yes, there's a keg down there, how do you open this."

Li An squatted down and saw the poop bucket, but for a short time he didn't see the switch to turn on the mechanism under his buttocks.

"Squire, here, just turn this little button slightly, and the gap will open."

Ang Lee tried it himself, and the gap was opened really easily.

"Yes, yes, even if this improved wheelchair is done, it can be given to King Xin'an today."

Li Ang is very satisfied with the improved wheelchair, although the biggest shock absorption problem still cannot be solved, but the two improvements are already very good, at least, can solve the actual situation that Li Yi is currently encountering, so that his life can be more convenient.

Subsequently, Li An sent several subordinates to deliver the improved wheelchair to the palace of King Xin'an and handed it over to King Xin'an.

The servants soon returned, and told Ang Lee that King Xin An was very happy to get the improved wheelchair, but blamed Ang Lee for not going there himself to talk to him.

It's not that Li An doesn't want to go to the mansion of King Xin'an in person, but he still has to go outside the city, and he hasn't checked the situation of the 500 acres of vegetable greenhouses for many days, and he also has to take a look at the reserves of honeycomb coal.

For honeycomb coal, Li An originally planned to introduce it to the market and make a lot of money for himself, but he already has a vegetable greenhouse, and there is no need to increase this income without lack of money, besides, in Li Anxin, this honeycomb coal has a greater use.

With the housekeeper Zhao Liu, Li An rode his horse to the south of the city for fifteen miles, and entered his own courtyard.

After many days of construction, the annex with an area of 50 acres has some rudimentary shapes, but it is not inhabitable for the time being. 【】

Li An and Zhao Liu walked around the courtyard, comforted the people who were working, and then went straight to the vegetable greenhouse.

After so many days of growth, the vegetables in the greenhouse have grown very big, and it will take at most half a month to be on the market one after another.

Looking at these results, Li An was very happy in his heart, he was not too greedy for money, but he didn't bite his hand when he had a lot of money! In this world, who will have trouble with money?

"Let's go, look at the reserves of honeycomb coal and coal."

Li An led Zhao Liu to the newly built warehouse to check how much coal was stored and how much honeycomb coal was made.

The little steward Wang Ba, who was taking a few male servants to make honeycomb coal, saw Li An coming, and greeted him with a smile.

"Ah Lang, this is the honeycomb coal stored here, and this is the coal dug from the coal mine in the south."

Wang Bayiyi introduced it and told Li An where everything was.

Li An followed behind Wang Ba and inspected several large warehouses, looking at the piles of honeycomb coal and coal, he was very happy, with these things, his own energy problem was completely solved.

Due to the large consumption of honeycomb coal in the 500-acre greenhouse, Wang Ba has to arrange people to go to the coal mine to transport coal every few days, which can save Li An a lot of money, and save money to hire people nearby.

However, due to the heavy weight of the charcoal, the amount of transportation at one time is very limited, and the road surface is inevitably bumpy, and the transportation is long, resulting in a road along the way turning black, which is not hygienic, and the transportation efficiency is also very low.

What can be done to make transportation more efficient and at the same time be more environmentally friendly?

Ang Lee thought of the trains of later generations, the trains traveled along the tracks, relatively stable, much stronger than the carriage, and the capacity was also incomparable to the carriage.

However, with the current level of science and technology in Datang, it is really too difficult to build a train, at least, Ang Lee thinks of the complex structure of the locomotive, and his head is too big.

It is difficult to build advanced trains in later generations, but it is possible to make a simple toy, at least, the rails are relatively easy to make, and Datang's scientific and technological level is completely competent.

Moreover, the railroad tracks that Ang Lee wanted to build were not quite the same as the rails of later generations, a little smaller, just like the small railroad tracks of coal mines in later generations.

The train carriages and wheels are not too difficult, and they should be relatively easy to build.

As for the locomotive, it is a big problem, but it doesn't matter if it can't be built for the time being, you can temporarily use horses to pull the carriage first, which is at least much less labor-saving than pulling a car on the flat ground, and the power problem can be solved slowly.

Of course, Ang Lee's idea is not bad, but if it is only to facilitate the direct transportation of charcoal, and use a large number of iron resources to build railroad tracks, there is a suspicion of wasting resources, but Ang Lee's purpose is to be able to find a way to make primitive wagons step by step in the future, and this fifteen-mile small railway track is just a small tool for Ang Lee's scientific research.

Li An told Zhao Liu beside him his thoughts, and Zhao Liu was surprised: "Ah Lang, just to save their effort, you have to lay railroad tracks, which is really not needed, and this requires a lot of iron, Datang strictly controls iron, and in a short period of time, I am afraid that I will not be able to buy so many iron raw materials." ”

"Haha! Then you should send more people and go to a few more places, so that you should be able to buy enough iron. ”

The railroad track that Li An wants to build is only fifteen miles, and it is still a miniature version of the railroad, which does not cost much to iron raw materials, and if you go to a few more places, you can naturally buy it.

"Ah Lang, if we buy iron on such a large scale, if someone finds out, and thinks we are going to build weapons to rebel? It's too dangerous. ”

Zhao Liu had been in the capital for many years and had seen similar things with his own eyes, so he naturally wanted to persuade Li An not to do stupid things.

"Zhao Liu, you don't have to worry, we bought iron materials to build railroad tracks, and we are not afraid of the imperial court investigation, at most it is just a false alarm, but once this railway track is laid, it will not only be much more convenient to transport coal in the future, but also more useful."

Ang Lee squinted his eyes and looked at it.

"Ah Lang, what better use is this?"

Zhao Liu obviously didn't understand the beauty of this, how could the backward people of this era understand the achievements of the industrial revolution in later generations?

"It doesn't hurt to tell you, if the railroad tracks are built, Ah Lang will also make a train that can transport a larger amount of goods, this train will far exceed the carriage, in the future, maybe the entire Datang road will be paved with rails, we don't need to take a carriage to travel, we can take the train directly, which is really convenient."

Li An said wistfully.

"All the roads in the entire Datang are paved with railroad tracks? Ah Lang, this will definitely not work, and I don't have so much iron in Datang! ”

The problem that Zhao Liu considered was very realistic, without so much iron, what would he use to make rails?

However, Li Anxin has already planned in his heart, at present, Datang has discovered a lot of iron ore, iron ore resources are extremely rich, but the mining method is very backward, basically with a sledgehammer to smash the iron ore piece by piece, and then crush and extract pig iron.

With such a primitive mining method, it is strange that enough iron can be obtained, and Li An envisioned using the black powder of later generations to collect iron ore, only need to dig a small hole in the iron ore, put the black powder into it, and use a rope dipped in oil to ignite it, so that with a bang, a large piece of iron ore will be blown up, and the mining speed will be increased by more than ten times.

Moreover, the blending of black powder is very simple, only sulfur, saltpeter and charcoal powder are mixed according to a fixed ratio, and these three items can be easily found in Datang, so that black powder can be manufactured in large quantities.

It's just that Li Anxin has always had a concern, that is, after the invention of black powder, what will it bring to the whole world, and what kind of changes will it bring to Datang? Will it make the already old Li Longji rekindle his ambition to conquer the world?

All this is unknown, and it is also the main reason why Li An has not dared to prepare black powder at will, at this moment, in order to improve the mining progress, for the future of Datang, Li An can't control so much, black powder must be manufactured.

"A-a-lang, A-a-lang."

A henchman hurriedly ran over.

"Ah Lang, this is evidence of the annexation of land by the Fan Yang Lu clan."

Li An glanced at it, and smiled lightly at the corner of his mouth: "Lu Shangyi, he is still an important person, he is in Chang'an City now, it seems that it is time to meet him." ”

At this moment, Li An's heart is sweeter than eating honey, with this evidence, he can completely behead Lu Shangyi, an important figure in the Fan Yang Lu family, but in this way, it will force the Fan Yang Lu family to death, which is not conducive to the overall pattern of the Tang Dynasty, in order to win over the Fan Yang Lu family, of course Li An will not behead Lu Shangyi, but the time to force Lu Shangyi to accept the two tax laws has obviously come.

"Zhao Liu, you send a few people to stock up on some iron materials, and I'll go back to the city first."

Li An and his henchmen rode back to Chang'an City, preparing to meet Lu Shangyi, the representative of the Fanyang Lu clan.

When Li Anze returned to the capital, Lu Shangyi, the representative of the Fanyang Lu clan, was reading an urgent letter sent by the family patriarch from the rear, the content of the letter was very simple, to prevent the implementation of the two tax laws as much as possible, and at the same time, not to be too far ahead, to hide behind the other families to cheer.

Of course, this is not the mind of the head of the Fan Yang Lu family alone, the patriarchs of the major families all hide the same Xiao Jiujiu, in the face of safeguarding interests, they will spare no effort, but they all understand the truth of shooting the first bird, so no family will be willing to stand in the first position.

"Father, the family patriarch is too worried, and now, Zheng Lao Liu of the Zheng family in Xingyang has been beheaded, and the Zheng family is already in the first place, now, we just need to wait for the Zheng family's reaction."

Lu Shangyi's son, standing next to him, of course also saw the letter from the patriarch of the family.

"What my son said is that now the Zheng family must be like ants on a hot pot, restless! We don't have to rush, we don't have to rush. ”

Lu Shangyi looked at his son with a relaxed face, and he felt like watching the fire from the other side.

Although, at this moment, their interests will be damaged by the implementation of the two tax laws, but the Zheng family is the first to be targeted, which makes them have a sense of schadenfreude, which is the so-called psychological balance!

I'm miserable, and there are people who are worse than me, so my heart is much more comfortable.

"Ah Lang, Li Shilang asks to see you."

A servant came over and reported to Lu Shangyi.

"Li Shilang? Which Li Shilang? ”

"Father, it must be Ang Lee."

"Ang Lee? What is he here for?"

Lu Shangyi suddenly felt a panic, Li An's beheading of Zheng Lao Liu, he had already heard about it, and the methods could be described as extremely ruthless, could it be that it was his turn next.

"Father doesn't have to be nervous, Ang Lee is here to visit, not to lead troops to arrest us, first explore his intentions, and then make plans."

"Okay, please."

"No need to please, Lu Yuanwai."

Li An broke in directly, although it was a little rude, but the subordinates of Lu Shangyi's mansion really didn't dare to stop him.

"Li Shaolang, haha! Rare guest, rare guest! Hurry inside please. ”

Lu Shangyi was taken aback for a moment, and then greeted Li An with a smiling face.

"Lu Yuanwai doesn't have to be polite, this official has nothing to do but go to the Three Treasures Palace, since he is here, he naturally has something to talk about."

Li Ang didn't bother to go around in circles with a family representative like Lu Shangyi, and directly named the theme.

"Dare to ask Li Shilang what happened?"

Lu Shangyi pretended to be surprised, as if he was a good citizen who abides by the law.

Ang Lee grinned, Lu Shangyi's acting skills are also very good, but they are a little worse than the actor level in later generations, and his expression is still a little stiff, not too natural.

"Lu Yuanwai should have heard about Zheng Lao Liu! See, these are all evidence of your recent annexation of land, and with this evidence, the official can exile your whole family according to His Majesty's holy decree. ”

Ang Lee said it quite directly, without the slightest euphemism.

When Lu Shangyi heard this, he was immediately paralyzed, his legs were a little trembling, he didn't expect that Li An would find his head so quickly, which also blamed him for being too greedy, in the Fanyang area, he already had a lot of land, but after going to Chang'an City, he was unwilling to lag behind other families, so he annexed two thousand acres of land in the capital, and because the matter was done by his subordinates, it also caused a murder.
