After three years of enfeoffment, the waste prince shocked the court boss

However, due to the low power of the existing gunpowder, easy to absorb moisture, inconvenient to transport, not resistant to storage, and troublesome to use, it is easy to explode and misfire, so many troops just throw it in the warehouse, preferring to use swords rather than this gunpowder. thing.

In the past six months, the gunpowder research team led by him has tried thousands of ratios day and night, tested countless kinds of binder materials, and finally came up with this kind of gunpowder that is close to the power described by An Wang at the time.

Mo Ling understood that once this new type of gunpowder came out, it represented invincibility on the battlefield.

"Is there any problem with the mass production of this gunpowder?"

Apart from power, what Li Su cares most about is the output. Otherwise, no matter how powerful this kind of thing is, if it only stays in the laboratory stage, it will be useless. What he wants is gunpowder that can be used in actual combat in the true sense.

"No problem, we have considered the mass production of the new gunpowder during the research process, and we have chosen the simplest production method, and the assembly line can be mass-produced."

Mo Ling patted his chest and promised.

"Go, go and try its power."

While researching artillery, Gewuyuan built several artillery for testing gunpowder by the way, which were completely built according to the artillery style used by the Dagan army.

Mo Ling led Li Su to an empty field in the back mountain, which was their usual testing ground.

It was originally experimented in the Gewu Institute of Lingnan University, but Jia Siyan drove it to the back mountain because of its amazing destructive power.

Two identical artillery pieces were placed side by side on the proving ground.

Commander Mo Ling filled the two cannons with strong gunpowder and dry black powder respectively, and placed solid iron balls.

At one command, light the fire.

"Bang!" "Bang!"

Following two loud bangs, two cannonballs fell respectively in front of the test site, stirring up waves of dust.

"How about the data?"

Li Su asked.

Although it can be seen with the naked eye that the landing points of the two shells are far apart, the data is still reliable.

"Your Highness, the black powder of the Dagan military shoots 320 meters away, while the artillery shells propelled by our strong gunpowder shoot 1000 meters away."

Mo Ling excitedly said to Li Su.

This data has refreshed the maximum range of his known artillery in this era.

"Is 1000 meters? Not enough. As far as I know, the artillery of the Western Francophones should be able to reach a range of 200 meters."

Li Su stroked his chin and pondered.

In the future, his eyes will be on the vast sea, and he will definitely meet the warships from the west.

If the range of your artillery is not as good as that of the opponent, your hope of conquering the sea will no longer exist.

The truth is always within range, and no one on the sea will respect you as a powerful vassal, they will only succumb to the caliber of your cannon.

"But our gunpowder is already the best ratio."

Mo Ling said with a bitter face, he didn't expect King An to have such high requirements on the power of the artillery.

"Didn't you try to improve the structure of the artillery? You must know that Dagan's artillery is suitable for the previous black powder, but may not be suitable for our strong gunpowder.

Now our materials should be strong enough to support the construction of larger caliber guns with longer barrels. "

Li Su suggested.

For technical issues, he can only provide corresponding ideas, and the specific implementation still needs to be figured out by these researchers.

Although he is a time traveler, he doesn't know everything after all, and he has only a half-knowledge of many things.

The system has not moved for a long time, and it is unrealistic to expect the system to lose a blueprint of the artillery.

"Let's try it, it should work."

A month later.

"Your Highness, Your Highness, it's done. The idea you provided is really good."

Mo Ling trotted to find Li Su who was talking to Jia Siyan at Lingnan University, and said excitedly.

Over the past month, he has built 37 cannons of different sizes, and finally found the most suitable cannon structure, which can withstand a larger amount of gunpowder loading.

For the sake of experimentation, eighteen bombs were blown up, and the students who finally managed to ignite strongly demanded that the fuse be made two meters long before they dared to ignite.

The sound of artillery in the back mountain has not stopped in the past month.

proving ground.

Li Su couldn't help but be speechless when he looked at the gigantic cast-iron body in front of him. This shape was very close to the red-clothed cannon he had seen in his previous life.

The manufacturing ability of the ancients is no worse than that of the modern people in the previous life, the only thing that is lacking is the idea.

As long as the mind is open, they can create what you think of.

"boom!"

As soon as the cannon blasted out, there was a burst of dust in the woods in the distance, and several trees were broken and fell down.

"This must be at least 2000 meters!"

Li Su guessed.

"Your Highness, the longest firing range is 2000 meters, and the effective firing range is about 300 meters. Moreover, as long as this gun is scaled up, it can shoot farther. It's just that it's not easy to transport no matter how heavy it is."

Mo Ling explained.

"Well, let someone make a hundred of them according to this first. I'm useful. The technology of artillery and gunpowder must be kept secret."

Li Su made arrangements.

The research institute of Lingnan University is definitely one of the safest places in Lingnan.

Since King Zhao sent Wang Kai to sabotage the last time, Li Su strengthened the guards of Lingnan University, especially the research institute.

Nightingale members were arranged in the dark to prevent anyone from spying on the things here.

South of Lingnan Prefecture, coastline.

There is a large frontier army stationed here, and it is under the jurisdiction of the main general Hou Zhengchang together with the border guards of the neighboring countries in the southwest.

In recent years, the neighboring countries in the southwest have been living in the south of the Five Ridges and earning a lot of money. Naturally, no one would dare to cause trouble.

Hou Zhengchang was also happy to be free, spending his whole day patrolling the border, and then thinking about how to spend his money.

"Your Highness, what wind brought you here."

Hou Zhengchang saw Li Su leading a group of people riding over, so he hurried up to meet him.

In the past few years, it has depended on King An to live a good life, so naturally he dare not neglect.

In fact, Hou Zhengchang often had the illusion that he was already a soldier of His Highness King An.

When a soldier eats food, he will sacrifice his life for whoever eats the food. As for how much of the court he still has in his heart, only he himself knows.

"Old Hou, this king has brought you a present."

Li Su smiled at Hou Zhengchang riding on the horse.

"Hey, His Highness still thinks of me. Since the last time he dragged us to the old city to renovate, he hasn't looked for me. I thought His Highness had forgotten us."

Hou Zhengchang said with an aggrieved face.

"Haha, isn't this a good thing for you!"

Li Su was also a little embarrassed, and threw him aside when he was done with them, feeling like he was a heartless person.

……

Chapter 95

"Your Highness, isn't this a cannon? There are ten cannons on my coastal defense line, and they are all rusted.

This thing is useless, it can only hit a few hundred meters, and it all depends on luck.

It can't be used in distant places, and it can't be used in nearby places. "

Hou Zhengchang looked at the cannon in front of him with an expression that was nothing more than that.

"When will the things that this king brought out be bad, just watch it, don't cry and ask me to keep a few more doors later."

Li Su joked.

Li Su asked people to remove ten cannons and installed them on the forts on the coastal defense line.

As the order to fire was issued, ten shells fired into the depths of the sea like meteors.

There is a group of reefs.

I saw the shells falling, except for three shells that missed and fell into the water, the remaining seven shells directly blasted the reef.

The towering reef group disappeared in half in an instant.

Hou Zhengchang stared at the scene in front of him in a daze.

He is very familiar with the reef group in the distance, and the oysters there are the most plump.

With nothing to do, he sailed there to pick up some sea oysters for a drink. It was a distance of 200 meters from the fort.

"Mother, how did this cannon hit so far!"

Hou Zhengchang had a look of incredulity.

"This is a new type of artillery that the king asked Lingnan University to develop. It uses the latest researched strong gunpowder, and the longest range can reach 2000 meters."

Li Su introduced.

"Oh, that's farther than those blue-eyed white men's boat guns!"

Hou Zhengchang exclaimed.

He had seen the Franc cannon.

With the development of Lingnan Prefecture, there is an endless stream of merchant ships at the docks by the sea, including the fleet of blue-eyed white men.

He had inquired about the artillery on those people's ships, and when he learned that their artillery could shoot 1000 meters away, he was a little apprehensive, for fear that they would suddenly turn into robbers and send some shots to his coastal defense force.

Fortunately, they are currently doing business honestly and have not done anything out of the ordinary, otherwise Hou Zhengchang really doesn't know how to deal with them.

"Do you still feel that this thing is useless?"

Li Su laughed.

"It's useful! It's useful! These are all for my old lord, right? Quickly unload, unload, don't tire the horse brought by His Highness."

Hou Zhengchang was afraid of Li Su's repentance, so he hurriedly asked the soldiers below to unload the new-style artillery pulled from the carriage.

"Your Highness, with these cannons, I don't have to worry about those Francobots turning their faces in the future. If anyone dares to covet our Lingnan goods, we will smash them for Your Highness."

Hou Zhengchang patted his chest and promised.

Li Su sent these cannons to Hou Zhengchang for exactly this purpose.

According to the news recently received from Nightingale, the number of foreign fleets coming to Lingnan Wharf for trading is increasing day by day, and many of them are armed to the teeth.

If the coastal defense forces are not strengthened, once a fleet coveting the wealth of Lingnan Prefecture wants to attack Lingnan by force from the sea, Lingnan Prefecture will have no power to fight back.

The current Lingnan warships have not yet launched, and only rely on these artillery to confine the enemy to the sea.

Fortunately, the coastline of Lingnan Mansion is not long, and these one hundred cannons are enough to form a deterrent firepower for the time being.

"Your Highness, I heard that His Highness is good at poetry, so why don't you leave a poem for this cannon?"

Hou Zhengchang said suddenly, rubbing his hands together, looking at Li Su expectantly.

In fact, Hou Zhengchang also has his own thoughts, he can't see Li Su's presence often like Cao Youde and Qi Yong.

Obviously, like them, he is an official of the Daqian court, but Cao Youde and Qi Yong have already regarded themselves as subjects of King An, and they are nothing, so they are a little impatient.

He also wants to actively get closer to His Royal Highness King An. This time, he wants to use a poem to get in touch with him. Will he be able to climb up and call himself a minister next time?

Hearing this, Li Su felt a little unnatural.

Where can I make poems, I plagiarize others, not to mention that no one will write poems for Da Pao, right?

"If your Highness is in trouble, just don't do it."

Seeing Li Su frowning, Hou Zhengchang thought that Li Su didn't want to do it, so he hurriedly said.

It's just that from Li Su's point of view, no matter how you look at it, it looks like a disappointed face, as if he was toyed with and then abandoned, which makes people feel unbearable.
