"Huhu...... Fourth, Uncle Four Emperors, what the hell is going on? ”

Where did Li Chengqian and the other four little guys experience this situation, and with great effort to eat milk, they finally managed to control the frightened horses, and they ran to Li Yuanba's side out of breath and asked out loud.

"I don't know, I hear the sound seems to be a camp in the northern suburbs, let's go, go over and take a look!"

Sensei said that it was them, and even Li Yuanba was stunned by this moment, and after hearing Li Chengqian's words at this moment, he simply didn't go to the Hongwen Pavilion, and directly turned the horse's head and went straight to the outside of the palace.

……

On the northern outskirts of Chang'an City, about a mile next to the tall city wall, there is a large area of camp enclosed with blue bricks.

From afar, seeing the tall cyan brick wall, Li Su couldn't help but say a little strangely: "Alas, I remember that this place was not all wooden fences before?" When did such a large area of green bricks be erected? Third brother, do you know? ”

"I haven't been out of the palace in a while!" Li Ke, who was riding on a horse and walking side by side beside Li Su, shook his head and continued: "Wouldn't you know if you went over and took a look?" ”

"Don't even speak, look at the appearance of the Fourth Emperor Uncle as if he knows there!" Li Chengqian glanced at the two younger brothers behind him and said.

Sure enough, I saw Li Yuanba's face in front of him, showing a look of sudden realization.

In fact, this camp was rebuilt by the imperial court at the expense of Li Yuanba, and the internal environment was extremely secretive, the 'Shenji Mansion'. Shenji Mansion is Li Yuanba's mention to Li Shimin, which is equivalent to the Ming Dynasty set up on special research. Sector for the manufacture of firearms.

And this was originally the camp of the left and right guards, and in normal times, in addition to the guards on duty. The rest of the guards will all be stationed here for daily drills.

Just half a month ago, the left and right feathers, who had received a secret order from the emperor, suddenly began to build on this camp.

Originally, it was nothing more than a camping place fenced off by a wooden fence, but it turned out to be a blue brick as high as a few feet. There are also some iron thorns embedded in the top of the green bricks, which are sharp and shining with cold light.

Over the next three days, things were brought in one after another, such as a furnace for striking iron, and various metal utensils. Dozens of truckloads of firewood, black charcoal, and a few other minerals wrapped in coarse cloth.

Since then, the entire camp has been guarded by the left and right guards, almost three steps and one post, five steps and one sentry, even at night.

……

Li Yuanba and other five people rode horses. The horse's hooves kicked up billowing smoke and dust, which immediately attracted the attention of the left and right guards who were guarding the Shenji Mansion a few feet away.

"Stop, who's coming!"

Far away, this team of nearly 100 people stood in front of Li Yuanba and the others, and also pulled up a barricade composed of sharpened wooden stakes and shouted loudly.

From childhood to adulthood, he has always been Li Su, who is used to being arrogant in this Chang'an City. Where was someone scolded like this, I was a little annoyed at the time.

Just when this kid wanted to scold out loud, he saw Li Yuanba in the front directly take out a small sign from his arms. Lost it.

The soldier who took the small sign looked at the small sign in his hand carefully, but after a while, his face changed greatly, and he clasped his fists and saluted: "The last general, Ye Fei, a hundred horsemen of the right guard, has seen His Royal Highness the King of Martial Arts, but I don't know that the prince has arrived." I haven't greeted you from afar, and I ask the prince to forgive me! ”

His Royal Highness King Wu? Rajah!

This is the one who is said to have only visited the Divine Machine Mansion once on the day it was completed. Since then, it has been sinking into the sea, and there is no trace of the controller of the 'Divine Machine Mansion'. Martial King Li Yuanba?

Stand corrected?

That's impossible, the small brand that Li Yuanba took out just now was specially made by the general as a supervisor, and there were two pieces in the entire Tang Dynasty, one on his body, and the other on Li Shimin, and each piece still had their respective names and surnames on it.

Therefore, after the soldier saw the small sign, he immediately saluted Li Yuanba in fear.

The other soldiers, seeing that their bosses had saluted, also hurriedly bowed together.

"Hmm!"

Li Yuanba nodded at the soldiers in front of the gods, and said, "This website asks you, what's going on with Fang Cai's voice?" ”

Respectfully returning the small brand in his hand to Li Yuanba's hand, Ye Fei replied: "If you go back to the prince, the last general will not know!" However, during this period of time, there have been frequent noises in the camp, but it is far less than today's movement! ”

"Oh, is that so?" Li Yuanba touched his chin and said, "You move this barricade, this king wants to go in and have a look!" ”

"No!"

Ye Fei responded, and hurriedly instructed his subordinates to move the barricade.

……

As far as Li Yuanba's layout is concerned, the entire Shenji Mansion was divided into five departments in the early days, the first department was the Weaving Division located on the east side of the camp, and the Weaving Bureau was responsible for making all kinds of iron tools, including all kinds of weapons.

The bureau gathered the best skilled craftsmen in the entire Tang Dynasty, and even the master craftsmen who would be the supervisors were dispatched to the past three.

This second department is located on the south side of the camp of the Ministry of Industry, the Department of Industry is the design and research of various weapons, which are some experts who are familiar with the various combat weapons of the past dynasties and the present, and it is said that there is also a ink master, I don't know whether it is true or false.

The third department is the fire on the west side of the camp. The Department of Medicine, as the name suggests, is here to specialize in fire. The place where the drug is dispensed.

Of course, the gunpowder that was blended could not be realized here, so a fourth department was born, the Test Division, located on the north side of the camp. Its main function is to test and verify whether the various weapons and firearms have achieved their intended objectives.

As for this fifth department, it is called the Dispatch Department, which is responsible for various logistical support work.

The five departments are divided and cooperated, and without any one department, the Shenji Mansion will not be able to operate normally.

At this moment, in the vast testing ground of the Shenji Mansion Test Bureau.

Four strong men in heavy armor lay on the ground and howled miserably, and more than 30 young men in white robes circled around the four strong men lying on the ground.

Not far away, on the ground, there was something like the base frame of a catapult, and in addition, within a radius of two hundred meters, there were stout wooden sticks that were either a few inches long or a few feet long.

Flames burned on the sticks, burning the dead grass on the ground.

On the ground around these burning sticks, there were countless small iron balls the size of small fingernails, and the small iron balls were so powerful that they smashed the ground into small deep pits.

All around, there is still a strong fire. Medicinal taste.

"What's going on?" Li Yuanba frowned and walked over, leading the four children over.

The people from the five departments of the Shenji Mansion were all personally selected by Li Yuanba after being screened by Guò, and all the people from these departments had seen Li Yuanba.

Although they were all surprised to see Li Yuanba, the shopkeeper at this moment, they were all surprised in their hearts, but when they thought of what had just happened, they replied to Li Yuanba: "Back to the prince's words, Fang Cai, it was the barrel of the boulder cannon that exploded!" ”

The boulder cannon was first used in the battle of Xiangfan in the Song and Yuan dynasties, because its inventor was a Hui person from the Western Regions, so it was also called a Hui cannon. Don't look at its name with a cannon word, but in fact it is a stone thrower, a weapon suitable for offensive and defensive wars.

However, the boulder cannon here is not a stone thrower, but a real cannon!

In the memory of Li Yuanba's previous life, there was a rudimentary but powerful cannon called the gasoline barrel cannon.

That guy is very powerful, he can bombard him at any distance, much stronger than that mortar, and he hits a large area, killing the cubs of the Japanese country is chickens and dogs, and the farts are flowing.

Li Yuanba fused the gasoline barrel cannon with the trebuchet, drew a few sketches, and handed them over to the people of the Ministry of Industry.

The guys from the Ministry of Works, who had never seen such a rare object, were all obsessed, and quickly began to perfect and design it.

To be honest, this thing doesn't really have much technical content, it's just a replacement of a gasoline drum with a fire. The medicine barrel is also filling the fire. Medicine kegs, as well as ignition, require better and safer methods.

Today, it's because of the wrong way to ignite the fire, so that the trebuchet hasn't had time to set it on fire. The medicine barrel was thrown, and it exploded in its place.

And fire. Powerful concussions when the charge is blasted, as well as fire. The countless small iron balls inside the medicine barrel are extremely powerful in attack, and they are the culprits responsible for this messy scene.

"Fire. A medicine barrel bursting? ”

Li Yuanba's face couldn't help but tighten when he heard this, and he hurriedly pushed away the few people in front of him and came to the innermost.

looked at the strong man lying on the ground, wearing the potholed iron armor, and said, "How are you, are you injured?" I said, what are you all doing in a daze, why don't you send him to the dispatch bureau quickly? If, because of you, the best time for their treatment is delayed, this king will ask for your head! ”

"No!"

The group of young men was startled, and hurriedly carried the four strong men towards the dispatch department.

Soon, this test site was vacant, and only the second-in-command of the test department, the waiter Lin Wei, accompanied Li Yuanba and Li Chengqian and others.

"Does this happen all the time?" Li Yuanba looked at the wandering patterns on the test ground, and his brows furrowed.

"If you go back to the prince, there will be a situation about once every ten times, the Ministry of Industry and the fire. Pharmacists are also looking for a solution! ”

Lin Wei replied respectfully.

This Lin Wei was originally the general of the Right Lingwei, because of his own strength and his interest in all kinds of novelties, so Li Yuanba deliberately picked him out of the Right Lingwei and left him in the Shenji Mansion.

"This fire. How many days has the medicine trebuchet been made? Li Yuanba's face gradually turned cold.

Lin Wei was stunned for a moment when he heard this, then frowned and thought about it, and said, "Seven days!" ”

"Hmph, seven days! For seven days, this happened every day, and the Ministry of Works and the fire. What do pharmacists do? Li Yuanba said angrily: "This king doesn't raise idlers in this magic machine mansion!" You go and put the Ministry of Engineering and the fire. The great priest of the medicine department has called this king here! (To be continued) R580
