Li Longji and Li An performed a show that made the ministers of the Great Tang’s highest authority more convinced that the configuration of black gunpowder requires 100 kinds of materials, and the process is extremely complicated, including grinding, steaming and steaming. Multiple steps, such as smoking, are all critical to the confidentiality of the formula.

The raw material area on the left side of the workshop is the focus of Li An’s introduction. It took almost one hour to finish the introduction. There is nothing to introduce in the large workshop in the middle. Li An said nothing on the grounds of confidentiality, just to bring everyone Walked around the big workshop, let everyone feel the open environment and a lot of misleading equipment in the big workshop.

There is only one configuration workshop in the rear, which is also the place where Li An will configure the black gunpowder products in the future. There are many vacant spaces on the left and right sides of the configuration workshop. Planting precious trees makes the entire configuration workshop look more elegant. From a distance, it looks down. Like a villa.

The right side is a low-rise house, and the cellar is also dug below to store the black gunpowder finished products. The reason why it is built underground is to prevent danger, and to maintain a sufficient distance between each two cellars, There are also security considerations to prevent a warehouse from exploding, and the surrounding warehouses will also explode. If there is a large-scale martyrdom, the entire black powder workshop will not exist, and the consequences will be terrifying.

Of course, the underground moisture is relatively large, and the gunpowder is relatively afraid of the tide. This was a big problem that troubled Li An. However, the black gunpowder stored underground is all finished products in pots and must be reliably sealed. So, even if placed in the humid environment underground, the black powder will not get wet.

As for the gunpowder package wrapped in sackcloth, it can also be sealed in a large pottery jar. Just like the later-generation water tank, a large pottery jar can be filled with a large amount of gunpowder pack, thus avoiding moisture.

Of course, these cellars will not be closed all the time, and will often open the ventilation, so that the moisture inside can be more radiated into the air, so as to reduce the humidity of the cellar as much as possible.

Looking at the huge cellar group, Li Longji and his subordinates were all stunned. Such a large cellar group, the black powder that can be stored, can almost blow up the entire Chang’an City to ruins.

“Minister Li, all of these cellars store black gunpowder. How long will it take?”

A senile official asked excitedly.

“This is not good. It depends on the preparation of materials and the number of workers. It is possible any time and cannot be estimated.”

Li An does not tell lies, after all, the configuration of black powder is very simple, as long as there is enough sulfur, saltpeter and charcoal powder to allow a sufficient amount of manual grinding, it is possible to complete it within a few days.

“How long will it take if the raw materials and labor are ready.”

The old minister continued to question.

“This one……”

Li An frowned for a while, opened the mouth and said: “If everything is in order, it is estimated that 2 months will be enough.”

In fact, of course, it does not take so long, but Li An ca n’t say it too easily, otherwise, how to explain the black powder needs more than 100 raw materials, and extremely complicated configuration process, which will make all previous misleading efforts in vain.

“Can these cellars be fully stored in just 2 months?”

The ministers all showed incredible expressions. Obviously, they did not expect that the configuration of black gunpowder would be so rapid, and in this way, the output of black gunpowder would be sufficient to meet the needs of Great Tang, especially the mining, in order to improve The mining efficiency requires a lot of black powder.

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

Li Longji looked towards Li An, said resolutely: “Minister Li, I will provide you with sufficient materials and manpower, and you will start taking office from tomorrow! At least 4 hours a day.”

“This Small Official.”

Li An nodded took the lead, but secretly sighed in my heart. Did Li Longji traverse, and actually understood the 8-hour work system, no more, no less, just let him work for 8 hours, but as long as he can complete the configuration task, Satisfying Li Longji and taking a day off for 2 days are acceptable. After all, is talent the most important thing? The excessive production of black gunpowder is also wasted, and it is enough to use it.

“Minister Li, I heard that your other yard is in the vicinity, and, you also got a rail and a wheel carriage next to the other yard. Is this the case?”

Li Longji suddenly changed the subject, and Li An was shocked. The group officials were stunned. They didn’t understand what is the railroad track and what was the iron wheel carriage.

“Your Majesty, this must be the secret of Duan Xiushi!”

Li An smiled and looked towards Duan Xiushi behind him. Although Li Longji and all the ministers were present and had more guards in the forest, Duan Xiushi still followed Li An. This was his responsibility.

“Duan Xiushi? Minister Li said, is the Yulin Military Captain behind him?”

Li Longji glanced at Duan Xiushi, and there was not too much impression in his mind. Although some of the 50 Yulin troops he sent were his eyeliners, he had to report to him daily, but Duan Xiushi was not among them. Even, Li Longji has never seen Duan Xiushi, but just heard Duan Xiushi ’s name many times when listening to the eyeliner report, knowing that Duan Xiushi and Li An are very close, and in front of Li An, they often make bold suggestions This kind of problem, people who don’t know, think they are confidant friends who have known each other for many years?

“Your Majesty’s eyes tell This Small Official that This Small Official seems to be wrong an innocent person.”

Li An laughed at himself and turned back to give Duan Xiushi an apologetic look, making the ministers around him unable to bear.

“Minister Li likes to invent and create, but it’s not a bad thing. Even if someone tells me, it’s a good thing. Why, looking at the meaning of Minister Li, I still want to hide it, I’m not happy to let me know!”

Li Longji frowned, but in no way can he be angry.

“Your Majesty is not This Small Official. I don’t want Your Majesty to know that it is this Small Official who has learned a little. At present, I haven’t done a good job on iron wheels.

Li An said modestly.

“Just a joke? Minister Li is too humble. I heard that the iron wheel car is much smoother than the carriage. I still want to take a look today and take a ride on this iron wheel?”

Li Longji didn’t laugh at Li An at all, but wanted to take a glance and experience the smoothness and comfort of the iron wheel carriage.

“Now that Your Majesty has been decided, This Small Official can only offer ugliness. The iron wheel is 5 miles to the south. This Small Official is willing to lead Your Majesty.”

Things have progressed to this point. Li An wants to refuse and it is impossible. Moreover, Li An also knows that these ministers who come with him will definitely go to see it as soon as possible. As it happens, Li An’s newly developed iron wheel head and iron wheel car should also be able to be tested, which is a great opportunity to show.

The matter was soon scheduled, a large number of Yulin troops set off in advance, and the water surrounding the road leading to Li An ’s courtyard was impassable, and dozens of ministers were all mounted, preparing to follow Li Longji ’s car and head to Li An ’s hospital.

“Your Majesty, This Small Official takes a step ahead and arranges first.”

Li An was worried that there would be a mess near the Beyond. He felt that he had to make arrangements in advance. He was even more worried that these guys who had never seen the world would be scared by Yulin Jun who arrived suddenly.

The nodded that Li Longji agreed to, with the help of Court Eunuch, walked into the carriage.

Li An Zema went straight to the processing plant next to the other courtyard, and saw many craftsmen standing there stupidly, none of them were working. Obviously, they did n’t understand how a large number of Yulin Army appeared beside them Feeling a little frightened, naturally there is no intention to work.

“Minister Li, you are here! How did these soldiers encircle us, I went to talk to them, they did not speak, like a dumb.”

An old craftsman walked anxiously beside Li An and asked nervously.

“You don’t have to be nervous. Your Majesty is here to inspect. They are here to protect Your Majesty.”

Of course, there is no need to hide this kind of thing. Moreover, Li Longji’s dragon driver will arrive soon.

“Your Majesty is coming, Your Majesty is coming.”

“Hear it! Your Majesty is coming.”

None of these craftsmen have ever seen Emperor. I heard that Emperor was coming to inspect it. They were all very excited. Being able to see Emperor with his own eyes, and being embellished with Emperor ’s nobleness, was also a pleasure for them.

“Right, is the iron wheel head built?”

Li An had no time to let these craftsmen savor the feeling of Emperor’s presence and asked directly.

“Minister Li, already built, right there.”

The craftsman reached for a finger and walked with Li An.

“Okay, very good. Today, Your Majesty is in person, and the front of the iron wheel will be tested in front of Your Majesty.”

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

Later, Li An quickly went to the vegetable greenhouse area, let Wang 8 and his maid work honestly, do not run into Your Majesty.

After arranging all this, Li An glanced at the railroad track again before taking a step to pick it up.

Li Longji’s car came just right. Li An just came out to greet him and he arrived.

“Your Majesty, the railroad track is not far in front.”

Li An took Li Longji and dozens of Imperial Court ministers to the railroad track.

“The line in front is the railroad track?”

Although Li Longji is old, but his eyes are not spent at all, he soon discovered the railroad track bulging above the ground.

“Yes, Your Majesty, that’s the railroad track, the carriage on the left is the iron wheel carriage that travels specifically on the railroad track.”

Li An introduced it while explaining the benefits of rail driving.

However, Li Longji not at all was too excited, and dozens of ministers shook his head again and again, feeling too unrealistic.

When they walked close to the railroad tracks, they even lamented Li An’s excessive waste of iron materials. If so much iron material, if it is used to build swords, it can be equipped with a considerable army, used to build agricultural tools. Benefit a large number of poor 100 people.

Of course, they didn’t understand Li An’s ultimate purpose, and it was normal to conclude that iron wasted, even Li Longji was not optimistic about Li An’s invention.

However, since it’s here, it’s good to experience it, so don’t try it in vain! Moreover, Li Longji would also like to know what Li An ’s final plan is. Through eyeliner introduction, he knows a little bit about Li An ’s final plan. The specific details are completely unclear.

“Minister Li, how long is this railroad track?”

“Back to Your Majesty, there are already 3 4 miles. If all are completed, the length is 5 1 miles.”

Li An’s calm answer.

“In 3 4 miles, it will take 5 1 miles to complete, how much iron will be wasted!”

“Yeah! Yeah! It’s a waste, this rail is really too much iron.”

“My Great Tang is rich in products, but it can’t stand such a toss!”

Some ministers, in private, began to sigh and felt that Li An was too bad. In order to smooth the carriage, he actually laid rails on the road.

“Huh, Minister Li, how can this carriage be the same before and after!”

Li An explained: “The iron wheel carriage is inconvenient to turn around, leaving a structure that can be tied to the horse before and after, for the convenience of turning around.”

At present, the rails used in the Li An experiment are still single-track rails. The iron carriage can be said to be simply unable to make a U-turn. Therefore, the carriage must be made and the horse can be tethered back and forth. Convenience.

“Minister Li, can I go up and experience it now?”

Li Longji is impatient now. He would like to know how it feels to be a railroad carriage.

“Your Majesty, please, This Small Official controls the carriage personally.”

Li An invites Li Longji to board the carriage, and sits in front of the carriage in person, drives the horse with a leather whip, and lets the carriage move forward slowly.

“Your Majesty, sit tight, This Small Official speeds up.”

Li An reminded that the speed of the iron wheel carriage has been increased.

Li Longji pulled the curtain, admired the scenery along the way, and predicted the speed of the carriage, and at the same time, felt the bumpiness of the carriage.

Li An does not dare to let the horses run too fast to avoid unpredictable risks, but at the same time, it does not allow the carriage to be too slow. Otherwise, what is the point of inventing the iron wheel carriage, which runs slightly faster than the ordinary carriage, this is The minimum requirement for Li Longji to approve, and the stability will definitely be recognized, there is no doubt at all.

3 The distance of Liduo soon came to an end. When there were 50 steps left at the end, Li An slowly slowed down, stopped the carriage, and jumped away from the carriage to untie the horse and re-tether it to the other side of the carriage one direction.

“Your Majesty, sit tight, let’s go back.”

Li An beat the horse with a horse whip, and accelerated again.

“Minister Li, don’t speed up, slow down, the slower the better.”

Li Longji didn’t want to end the experience anytime soon. Moreover, he still had something to say to Li An.

“Yes, Your Majesty.”

Li An hearing this, Le Ma slow down, let the iron wheel carriage speed as slow as possible.

Before the Li Longji experience, the 3 side of the 2 mile long railroad track was filled with generals of Yulin, in order to naturally protect the safety of Li Longji, and the safety of Emperor can not be sloppy.

However, Li Longji looked towards the eyes outside the car curtain, but did not stay at all on these feather generals.
