Li Longji and Li Anxin tacitly staged a scene, which made the ministers of the highest authority of the Tang Dynasty even more convinced that the configuration of black powder requires hundreds of materials, and the process is extremely complex, with multiple steps such as grinding, steaming and fumigation, all of which are crucial to the secrecy of the formula. Pen ~ fun ~ pavilion www.biquge.info

The raw material area on the left side of the workshop is the focus of Li An's introduction, it took almost half an hour to introduce, and there is nothing to introduce in the big workshop in the middle, Li An didn't say anything on the grounds of secrecy, just took everyone to walk around the big workshop, so that everyone could feel the empty environment of the big workshop and a large number of misleading equipment.

There is only one configuration workshop in the rear, and it is also the place where Li An will configure the finished black powder in the future, and there are many open spaces on the left and right sides of the configuration workshop, and valuable trees are planted, so that the entire configuration workshop looks more elegant, and from a distance, it looks like a villa.

On the right side are low houses, and there are also cellars dug underneath, which are used to store finished black powder products, and the reason why they are built underground is to prevent danger, and to maintain enough distance between each two cellars, there are also safety considerations, to prevent a warehouse from exploding, and the surrounding warehouses will explode together, if there is really a large-scale explosion, the entire black powder workshop will not exist, and the consequences are quite terrible.

Of course, the underground moisture is relatively large, and the gunpowder is more afraid of moisture, which was a big problem that bothered Li An at the beginning, but the black powder stored in the ground is all finished products in clay pots, and it must be reliably sealed, so that even if it is placed in the humid environment underground, the black powder will not be damp.

As for the gunpowder bag wrapped in linen, it can also be sealed in a large clay pot, just like the large clay pot of the water tank in later generations, a large number of gunpowder bags can be put into it, so as to avoid moisture.

Of course, these cellars are not always closed, and are often opened to ventilate so that more moisture can be dissipated into the air, so as to reduce the degree of moisture in the cellar as much as possible.

Looking at the huge cellar group, Li Longji and all the courtiers under his command were all stunned, such a large cellar group, the black powder that could be stored, could almost blow up the entire Chang'an City into ruins.

"Li Shilang, how long will it take for all these cellars to store black powder?"

An old official asked excitedly.

"It's not good to say, it depends on the preparation of materials and the number of workers, how much time is possible, and it is impossible to estimate."

Li An didn't tell a lie, after all, the configuration of black powder was very simple, as long as there was enough sulfur, saltpeter and charcoal powder, and a sufficient amount of manual grinding, it was possible to complete it in a few days.

"If the raw materials and labor are complete, how long will it take?"

The old minister continued to ask.

"This ......"

Li An frowned and pondered for a while, and then said, "If everything is fine, it is estimated that two months will be enough." ”

Actually, of course, it won't take so long, but Ang Lee can't say it too easily, otherwise, how to explain that black powder requires more than a hundred kinds of raw materials, as well as an extremely complicated configuration process, which will make all the previous misleading efforts in vain.

"It only takes two months to fill all these cellars?"

All the ministers showed incredible expressions, obviously, they did not expect that the configuration of black powder would be so rapid, and in this way, the output of black powder would be enough to meet the needs of Datang, especially for mining, in order to improve mining efficiency, a large amount of black powder is needed.

Of course, if these ministers knew that it would only take a few days, they would faint.

Li Longji looked at Li An and said, "Li Shilang, I will provide you with enough materials and manpower, and from tomorrow, you will start to take office!" At least four hours a day. ”

"We're in command."

Li An nodded to accept the order, but secretly sighed in his heart whether Li Longji had crossed over, and he actually understood the eight-hour work system, no more, no less, just let himself work for eight hours, but as long as he can exceed the configuration task and make Li Longji satisfied, it is acceptable to work for one day and two days off, after all, is talent the most important? Black powder is a thing that is produced too much and wasted, and it can be used enough.

"Li Shilang, I heard that your courtyard is nearby, and besides, you also built a railroad track and an iron-wheeled carriage next to the courtyard, is there such a thing?"

Li Longji suddenly changed the topic, which made Li An suddenly startled, and the ministers were even more stunned, not understanding what a railway track was and what an iron wheel carriage was.

"Your Majesty, this must be Duan Xiu's secret!"

Li An said and looked at Duan Xiushi behind him with a smile, although Li Longji and all the ministers were present and there were more Yulin Army guards, Duan Xiushi still followed Li An, this was his responsibility.

"Duan Xiushi? What Li Shilang said was the captain of the Yulin Military Academy behind him? ”

Li Longji glanced at Duan Xiushi, and did not have much impression in his mind, although some of the fifty Yulin troops he sent were his eyeliner and had to report to him every day, but Duan Xiushi was not among them, and even, Li Longji had never seen Duan Xiushi, but when he was listening to the eyeliner report, he had heard Duan Xiushi's name many times, and knew that Duan Xiushi and Li An were very close, and in front of Li An, they often boldly asked various questions.

"Your Majesty's eyes tell Weichen that Weichen seems to have wronged a good person."

Li An laughed at himself, turned around and gave Duan Xiushi an apologetic look, which made the ministers around him couldn't help but be happy.

"Li Shilang likes to invent and create, and it's not a bad thing, even if someone tells me, it's a great thing, what, depending on what Li Shilang means, he still wants to hide it, and he doesn't want me to know!"

Li Longji frowned, but he didn't look angry at all.

"Your Majesty, it's not that Weichen doesn't want His Majesty to know, it's really that Weichen is only a shallow learner, and he hasn't done a good job of the iron wheel car yet, so he can't do it a little bit, for fear of causing jokes."

Li An said modestly.

"Jokes? Li Shilang is too modest, I heard that the iron wheel car is much more stable than the horse-drawn carriage, I still want to stop by today to have a look, and take this iron wheel car myself? ”

Li Longji did not mean to laugh at Ang Lee, but wanted to see it and experience the smoothness and comfort of the iron wheel carriage for himself.

"Since Your Majesty has decided, then Weichen can only sacrifice ugliness, the iron wheel is five miles away to the south, and Weichen is willing to lead the way for Your Majesty."

Things have progressed to this point, and it is impossible for Li Ang to refuse, and Li Ang also knows that these ministers who have followed will definitely go to see it. It just so happens that the iron wheel front and iron wheel carriage newly developed by Ang Lee should also be able to be tested, which is a great opportunity to display.

Things were quickly arranged, a large number of Yulin troops set off in advance, and the road leading to Li An's courtyard was blocked, and dozens of ministers also got on their horses, preparing to follow Li Longji's car and go to Li An's courtyard.

"Your Majesty, Weichen is one step ahead and will arrange it first."

Li An was worried that there would be a mess near the courtyard, and felt that he had to arrange it in advance, and he was even more worried that these guys who had never seen the world would be scared out of trouble by the Yulin Army who suddenly arrived.

Li Longji nodded in agreement, and with the support of the eunuch, he walked into the carriage.

Li Anze rode straight to the processing plant next to the courtyard, and saw that many craftsmen were standing in it stupidly, none of them were working, obviously, they didn't understand how a large number of Yulin troops could appear around, and they felt a little scared in their hearts, so naturally they didn't have the heart to work.

"Li Shilang, you're here! When I went to reason with them, they didn't speak, they were dumb. ”

An old craftsman walked up to Li An's side in a nervous mood and asked nervously.

"You don't have to be nervous, Your Majesty is here to inspect, and they are here to protect Your Majesty."

Of course, there is no need to hide this kind of thing, besides, Li Longji's dragon drive will arrive soon.

"Your Majesty is coming, Your Majesty is coming."

"Hear me! Your Majesty is coming. ”

None of these craftsmen had ever seen the emperor, and when they heard that the emperor was coming to inspect, they were all very excited, and they were very happy to see the emperor with their own eyes and touch the emperor's luxury.

"By the way, is the head of the iron wheel finished?"

Li An didn't have time to let these craftsmen savor the feeling of the emperor's arrival, and asked directly.

"Li Shilang, it's already been built, it's over there."

The craftsman stretched out his hand and walked over with Ang Lee.

"Okay, very good, today, Your Majesty is here in person, and the head of the iron wheel will be tested in front of Your Majesty."

Li An looked at the front of the iron wheel and was still very confident in the guy he developed.

Subsequently, Li An quickly went to the vegetable greenhouse area, and asked Wang Ba and the male servants under his command to work hard and not collide with His Majesty.

After arranging all this, Li Ang glanced at the railroad tracks again, and then stepped forward to pick up the car.

Li Longji's car arrived just right, and as soon as Li An came out to greet him, he arrived.

"Your Majesty, the railroad tracks are not far ahead."

Li An took Li Longji and dozens of court ministers to the location where the railroad tracks were laid.

"The line ahead, the railroad tracks?"

Although Li Longji was old, his eyes were not dazzling at all, and he soon discovered the iron track road that bulged out of the ground.

"Yes, Your Majesty, that's the rails, and the carriage on the left is the iron-wheeled carriage that travels on the rails."

While introducing, Ang Lee explained the benefits of rail driving.

However, Li Longji did not have too excited expressions, and dozens of ministers shook their heads again and again, feeling that it was too unrealistic.

When they walked near the railroad tracks, they lamented that Li An was too wasteful of iron, so much iron, if used to make swords, could equip a considerable army, used to build agricultural tools, and also benefited a large number of poor people.

Of course, they didn't understand Ang Lee's ultimate purpose, and it was normal to come to the conclusion that iron was wasted, and even Li Longji was not optimistic about Ang Lee's invention.

However, since you're here, it's good to experience it, so you can't just come for nothing! Moreover, Li Longji also wants to know what Ang Lee's final plan is, through the introduction of eyeliner, he knows a little bit about Ang Lee's final plan, but the specific details are completely unclear.

"Li Shilang, how long has this track been laid?"

"Back to Your Majesty, it will already be three or four miles, and if it is all completed, the length will be fifteen miles."

Ang Lee replied calmly.

"Three or four miles, it will take fifteen miles to complete everything, how much iron will be wasted!"

"Yes! Oh, yes! It's a waste, it's too much of a waste of iron. ”

"Although my Datang is rich in products, it can't withstand such a toss!"

Some ministers began to sigh in private, feeling that Ang Lee was too loser, and actually laid railroad tracks on the road for the sake of the carriage walking smoothly.

"Hey, Li Shilang, why is this carriage the same before and after!"

Li An explained: "It is inconvenient for the iron-wheeled carriage to turn around, and there are structures in the front and rear that can be tied to the horse, so that it is convenient to turn around. ”

At present, the railroad track used by Li An's test is still a single-track rail, and the iron-wheeled carriage can be said to be unable to turn around at all, so the carriage must be built, and the horse can be tied to the front and back, so that as long as the horse turns in another direction, it is very convenient.

"Li Shilang, can I go up and experience it now?"

Li Longji is now impatient, and he wants to know what it is like to be a railroad carriage.

"Your Majesty, please, Weichen personally drives the carriage."

Li An asked Li Longji to board the carriage, and personally sat in front of the carriage, drove the horses with a leather whip, and let the carriage move forward slowly.

"Your Majesty, sit firm, Weichen has accelerated."

Li An reminded and increased the speed of the iron-wheeled carriage a little.

Li Longji pulls the curtain to enjoy the scenery along the way, and predicts the speed of the carriage, and at the same time, feels the bumpiness of the carriage.

Li An didn't dare to let the horses run too fast, so as not to have unpredictable risks, but at the same time, he couldn't let the carriage be too slow, otherwise, what was the point of inventing the iron-wheeled carriage, running slightly faster than ordinary carriages, this is the minimum requirement for Li Longji to recognize, and the smoothness will definitely be recognized, there is no doubt about this.

The journey of more than three miles soon came to an end, and when there were still fifty steps left from the end, Li An slowly slowed down, stopped the carriage, and jumped out of the carriage, untying the horse and tying it back to the other direction of the carriage.

"Your Majesty, sit tight, let's go back."

Ang Lee whipped the horses with his whip and accelerated again.

"Li Shilang, don't speed up, slow down, the slower the better."

Li Longji didn't want to end the experience anytime soon, besides, he still had something to say to Ang Lee.

"Yes, Your Majesty."

When Li An heard this, he slowed down the horse, so that the speed of the iron-wheeled carriage was as slow as possible.

Before Li Longji's experience, both sides of the three-mile-long railroad track were full of soldiers of the Yulin Army, in order to naturally protect Li Longji's safety, and the emperor's safety could not be sloppy in the slightest.

However, Li Longji's eyes looked outside the car curtain, but he did not stop at all on these Yulin Army soldiers. (To be continued.) )
