Li Longji's eyes were completely attracted by the large number of vegetable greenhouses on both sides of the railroad tracks, when he was in Li An's mansion, he had seen vegetable greenhouses, for this reason, he also asked the Ministry of Industry to paint a scoop according to the gourd, and also built one in the Daming Palace.

It's just that the construction of the black powder workshop has been delayed for more than half a month, and at this time, even if the construction is completed immediately, it is not very useful, after all, the weather will soon warm up, and there will be no need for greenhouses.

"Li Shilang, you actually built hundreds of acres of vegetable greenhouses here, how are the vegetables in it growing, and are they edible?"

Li Longji looked at these vegetable greenhouses and asked in a low voice.

"Back to Your Majesty, nearly half of the vegetables have begun to ripen, and now on the market in Chang'an City, the vegetables sold are shipped out from here, and when Weichen comes over every day, he will personally pick a few custarks to fill his stomach."

Ang Lee replied with a smile.

"Gherkins? As soon as Li Shilang said this, I was also greedy, and it is estimated that if those ministers knew, they would definitely be the same as me, haha! ”

The breeze blew through the car curtain on Li Longji's face, making Li Longji feel good and speaking very gently.

The emperor will also be greedy, and because of the little cucumber, Li An couldn't help but snort, but soon became indifferent, after all, the emperor is also a human being, and the emperor can't eat fresh cucumbers in winter, and it's still natural for him to be greedy.

"Your Majesty, in Wechen's greenhouse, there are many cucumbers, Your Majesty and the ministers can go in and pick them in person, no matter how much they pick, Wechen will not feel distressed."

Li An said very generously, these cucumbers are not valuables, of course he will not feel distressed, and let the emperor and the ministers go in to pick them in person, so that they can experience the pastoral fun of picking, and soothe the nervous system that usually works hard, which is good for their bodies.

"Okay, this is what Li Shilang said himself, later, I'm not welcome, I must pick a few more."

Li Longji also smiled, the two of them, one is a household servant, and the other is the king of a country, they are both people with high status and status, how can they care about a few cucumbers, such a conversation, just for fun and fun.

High-level people are more stressed, and sometimes they need to use humorous language to adjust their mood to ease the depression in their hearts.

Under the gaze of dozens of ministers, the carriage slowly stopped, and Li An, who had been a groom, jumped down from the carriage, and Li Longji slowly walked off the carriage with the support of several little eunuchs.

"Ladies and gentlemen, since you are all here, you can also experience it!"

Li Longji asked the courtiers to experience the iron-wheeled carriage, and he himself walked to the big waterwheel next to him, and seemed to be very interested in the big waterwheel.

"Li Shilang, the water supply of these 500 acres of vegetable greenhouses depends on these two waterwheels!"

Li Longji looked at the small ditch around him, and then looked at the water surface that was more than a foot deep, and gave his own judgment.

"Your Majesty Shengming, the hundreds of acres in the south are better, you can get water nearby, the terrain in the north is too high, and it is extremely difficult to get water, so in order to get water conveniently, Weichen thought of the waterwheel, and there are many waterwheels in the south of the Tang Dynasty, however, the waterwheel built by Weichen is better than the waterwheel in the south, and some improvements have been made."

Ang Lee introduced the origin and function of the waterwheel, and asked Wang Ba to immediately find a group of male servants to demonstrate how to use the waterwheel.

When the ten male servants stand on the pedals of the waterwheel and press the pedals hard, the pedals begin to rotate slowly, and when they rotate more than a certain degree, the river water in the bamboo tube pours down, pours into the ditch below, and flows laterally along the ditch, and finally flows to the vegetable greenhouse area.

"Waterwheel, that's a good thing! It can greatly reduce the manpower to get water, and it should really be popularized throughout the world, so that all fields in the world can use waterwheels! ”

Li Longji expressed his heartfelt emotion.

"Your Majesty, the waterwheel is made of wood and bamboo, only the rotating part is made of copper, it is not too difficult to popularize, Weichen will hand over the drawings of the waterwheel to the Ministry of Industry, I believe that with the speed and ability of the Ministry of Industry, things will be done soon."

Li An praised the Ministry of Industry here, in terms of rushing to build a black powder workshop, the Ministry of Industry did a very good job, of course, it also gave Li An a very good impression, and there is no difficulty in building a waterwheel, compared with the construction of water conservancy, the manpower and material resources required to build a waterwheel are relatively small, and spring ploughing is about to come, and it is still too late to start building a waterwheel at this time.

When Li Longji heard this, he nodded again and again, and prepared to let the Ministry of Industry be responsible for matters related to the popularization of waterwheels, so as to promote the development of agriculture, improve the national strength of the Tang Empire, and improve the living standards of the people.

In order to improve his knowledge of the waterwheel, Li Longji personally went into battle, and he had to personally push the waterwheel to let the water flow into the ditch next to it.

This frightened the several eunuchs who were waiting, but the waterwheel designed by Li An was still very safe, and Li Longji would not be in the slightest danger, and because the waterwheel was relatively heavy, Li An and several Yulin Army soldiers accompanied Li Longji to step on the waterwheel and successfully led the water flow, which made Li Longji very happy.

Although it is not all his own strength, but in these currents, there is also his own strength, which is enough to make him happy.

Although the ministers felt that Li Ang laid the railroad tracks, it was a waste of iron, but when they let them experience it, they did not object, and ran over, and the carriage designed by Li An was relatively large, and dozens of ministers could experience it all in two batches.

After getting off the iron-wheeled carriage, all the ministers sighed that the iron-wheeled carriage traveled on the rails, which was indeed much more stable than the ordinary carriage traveling on the dirt road, but they still felt that this was unrealistic, too wasteful of iron, and a kind of loser-style behavior.

After getting off the carriage, these ministers also gathered around the waterwheel, and followed in the footsteps of Li Longji, and also began to personally carry the water of the river more than a foot deep into the ditch next to it.

After giving the order and letting the Ministry of Industry be responsible for promoting the waterwheel, Li Longji looked at the courtiers and said loudly: "Ladies and gentlemen, Li Shilang said, all the vegetables and fruits in his vegetable greenhouse, you can pick as many as you want, don't be stunned, hurry up and pick vegetables and fruits with me!" ”

After speaking, he strode towards the vegetable greenhouse not far away, most of these ministers are in their forties and fifties, and they belong to older people, but as soon as they heard about picking vegetables and fruits casually, they all followed with a smile, just like a bandit leader, taking a group of bandits to rob, not to mention how active.

Ang Lee had more important things to do, so he didn't follow him, besides, all the vegetables grown in this greenhouse are his property, can he feel comfortable watching others team up to grab their own vegetables? It's better not to see it, and if you can't see it, you won't feel distressed.

Of course, Li An did not accompany Li Longji in person after obtaining Li Longji's consent, and the reason he gave was the word distress in a joking nature, which made the ministers laugh and were even more determined to pick more, which made Li An's heart hurt even more.

Li An suddenly felt that these ministers were all good or bad, they were all old bastards, and none of them felt sorry for themselves.

"Come here, pull the cart away, hurry."

Li An commanded several male servants to push the iron-wheeled horse-drawn carriage to the processing factory not far away, and asked the craftsmen of the processing factory to pull out the iron-wheeled locomotive and the iron-wheeled carriage to prepare for the test on the rails.

Although the front and carriage were relatively large and cumbersome, fortunately, the distance was very close and there were enough manpower, so in a very short time, the iron wheel locomotive and the iron wheel car were pushed onto the rails.

The locomotive was the first to get on the tracks, and the carriage was one step later on the rails, and then, under the command of Ang Lee, the locomotive and the carriage were connected together, and they were connected with iron materials, which was very strong.

The front of the car is a structure of three sets of driving wheels, which are separate from each other, and can be controlled by up to eighteen people, but Li An felt that it was completely unnecessary, so he found twelve male servants, and four people were responsible for a group of driving wheels, so as to drive the front of the iron wheel locomotive to run forward and drive the large carriage behind.

The appearance of the iron wheel carriage is modeled after the appearance of the later train carriages, and there are also seats arranged inside, a total of twelve rows, each row of four seats, connected by twos and twos, and there is an empty aisle in the middle.

Since Datang did not have the ability to make glass in this era, silk curtains with high transparency were hung at the position of the windows, and heavy objects were hung at the bottom of the silk to avoid the silk from being blown by the strong wind, thus losing the wind-blocking effect that the windows should have.

In short, Ang Lee thinks that the carriage he designed is very good, and the difference from the carriage of later generations is not much, as long as the front of the car can be successful, it is more than enough as a passenger train.

Because it was the first time to conduct an experiment, Ang Lee did not let the carriage carry passengers, he stood at the junction of the carriage and the front of the car, and directed the twelve male servants at the front of the car to pedal and drive the front of the car forward.

"It's moving, it's moving, it's great, keep it up!"

Seeing the front of the car slowly moving forward, Ang Lee's spirits were greatly lifted, and he encouraged the twelve male servants to continue to drive forward.

The speed of the vehicle became faster and faster, and soon it was equal to the speed of the horse-drawn carriage, and it was very smooth, much more stable than that of a horse-drawn iron wheeled car.

This is because the person who drives the car is sitting on the front seat, and the horse runs between the tracks, and the body will vibrate and transmit it to the iron wheel carriage, that is, using human power to drive the front of the car and drive the carriage behind it is much more stable than that of a horse pulling a cart, and when the speed is not very high, there is no vibration at all.

Ang Lee was overjoyed by the success of the experiment, and there was nothing more exciting than success, and when he was about to reach the edge of the tracks, Ang Lee ordered the brakes, and the front of the car slowly stopped, and the carriage also stopped.

"Turn around and go back."

The human-powered drive system designed by Ang Lee can be reversed, and the pedals can only be pushed backwards as long as a mechanism is toggled, so that the front of the car can drive backwards.

Of course, people can also sit upside down, which makes it easier to use the power of their legs to drive the front of the car with greater force and push the car back to the starting position.

When Li An returned to the starting place by carriage, Li Longji and dozens of important ministers under his command had already left the vegetable greenhouse and gathered around the waterwheel to wash cucumbers, ready to taste these fresh melons and fruits in person.

However, what Li An didn't expect was that these ministers not only held it in their hands and in their arms, but also asked Wang Ba and the servants to help them pack a lot.

Looking at these large bags of vegetables, Li An wondered if these court officials were fake, and they actually packed vegetables so excessively, and asked his servants to help pack them.

"Li Shilang is back, thank you Li Shilang, haha!"

"Thank you Li Shilang for the vegetables, this official doesn't have to eat radishes every day these days."

"Thank you, thank you."

These usually serious court officials, at this moment, were chewing crisp cucumbers while gloating and thanking Li An.

Looking at their happy smiling faces, Li An's heart was in tears, these vegetables were his own hard work, and it was already painful for them to pick them, but they didn't expect that they would pack them and take them away.

Of course, Li An's heartache was only a momentary thing, and the scars were quickly healed, and at this time, Li Longji, who was chewing cucumbers, and the ministers found the carriage in which Li An was riding, as well as the front of the car with more than a dozen people in front.

"Li Shaolang, what is this, it's a lot bigger than the iron wheel carriage just now!"

"Oh, what is this?"

All the ministers looked at the new guy newly developed by Li An, and their curious eyes did not match their age at all.

"Li Shilang, what is this?"

Li Longji had already finished eating a tender cucumber and strode over.

"Back to Your Majesty, this is the iron wheel locomotive and iron wheel carriage newly developed by Weichen, and it has been tested, and the effect is much better than the iron wheel carriage just now, more stable and reliable, and because it is driven by manpower, there is no need to worry about the trouble caused by the fright of the horse."

Li An introduced seriously.

Li Longji suddenly became interested, looked around the carriage and the front of the carriage for a long time, and said excitedly: "I originally planned to return to the palace immediately, but since Li Shilang said that this is more stable than the carriage just now, of course I have to give it a try." ”

"Your Majesty, this carriage is quite large, there are forty-eight seats in it, which can meet the needs of forty-eight people at the same time, even if all the ministers get on the train, it is enough to drive freely."

Ang Lee patted his chest and reassured.

Li Longji smiled and said loudly: "In this case, you Aiqing will ride with me to see if the new guy developed by Li Shilang can be pulled." (To be continued.) )
