The weather was cooler in early autumn, but it was still very hot in the mines.

Luo Lan and his entourage rode horses and traveled all the way north. The reason why the north was chosen was because the roads in the north were much wider, and the north should have been more thorough in those days.

While he was still on the way, Rick was completely excited, and he asked questions next to Daisy, eager to swallow Daisy.

If he hadn't known Rick's personality, Luo Lan would have suspected that he was a pervert.

Daisy has always been very shy, especially when there are many people, there are miners and guards, there are no less than thirty people, Daisy is very uncomfortable.

Or Bina understood the girl's thoughts, and quickly drove Rick away, and she and Daisy walked side by side, whispering all the way, snickering from time to time.

Half an hour later, the jungle ahead was dense, and although there were still roads, they were much narrower.

Daisy also spoke timidly at this time: "I'll take a look here......"

Her excited and nervous gaze swept over the barren mining area, and there was a throbbing in her heart.

Luo Lan signaled casually, and Daisy immediately dismounted, carrying her own special sack and running near the mine. Bina and Rick hurried to follow, and Barrett sent a few guards to protect them.

Luo Lan didn't join in the fun, because he was not an expert, he didn't even know sulfur, and if he went, it would be a mess, and he was more used to making some big decisions.

He summoned Barrett, who was gnawing corn, "Is there a volcano on Phuket Island"?

This was a thoughtless sentence, which made Barrett stunned for a moment, and then he pointed to the south, "I heard that there are in the Southern State, in the fief of Count Abbe."

Which country China?

Luo Lan couldn't help but raise his eyebrows, speaking of which, Guohua is really a thorn in his heart, but Count Abbe's reputation is not bad, and the southern state was even a paradise before.

Luo Lan groaned, and in his exchange with Daisy about gunpowder, Daisy mentioned volcanoes and sulfur stones several times.

Sulfonite is sulfur, which is an indispensable raw material for making gunpowder, and there is a large amount of natural sulfur near the volcano.

If the amount of sulphur in the West Coast mines was low, it would be a fatal obstacle to gunpowder manufacturing. Although sulfur can be obtained by refining pyrite, it is too expensive.

"Your Highness, do you want to go to the Southern State again?"

Barrett looked at Luo Lan frowning, and couldn't help but ask cautiously, he didn't want to see Luo Lan attack the southern state.

Luo Lan shrugged, "It's my own territory, it's too shameless to send troops to attack, I'll try to let the southern states take the initiative to submit."

Ignoring Barrett, who was gnawing corn, Luo Lan rode around the mine on horseback, while the fellow miners wandered around the neighborhood, wanting to see if there were any iron mines.

Unfortunately, there is not a single iron hair, let alone gold, in this mining area on the West Coast.

However, Luo Lan found something to be happy about.

The caves are generally too shallow, and according to his sights, the deepest caves are only seven or eight meters, and the miners will give up after digging seven or eight meters without finding gold or iron ore.

Because of the limitations of digging tools, miners in the past could only dig one pit and lose one pit.

"If there is gunpowder, you can dig deep into the mine, I don't believe that there is no iron ore in such a big mountain."

Luo Lan secretly thought in her heart, resources are too important, and she will have confidence if she has them.

At this time, Rick shouted excitedly from a mine: "Your Highness, Daisy said that explosive bombs can be made here!" ”

Luo Lan was overjoyed, Daisy recognized here!

He hurriedly ran over, and Daisy and the others just came out. Daisy was overshadowed by the stars, and her face was full of coquettish smiles.

She was finally less shy at this point.

"Your Royal Highness Luo Lan, please send someone to grind charcoal powder and collect saltpeter, there is sulfur stone here, I can make the first batch of gunpowder in two days, and then use earthen jars to process it into explosive bombs."

Daisy's words were very clear, Luo Lan was overjoyed, if it weren't for the presence of outsiders, he would have to hug this cute little Lori.

"Is there a lot of sulfonite?"

Suppressing her excitement, Luo Lan asked.

"It's still quite a lot, and there are probably hundreds of bombs that can be made here, and as for the rest of the places, we have to look at it again."

A hundred explosive bombs are comparable to missiles for people in this world, but what Luo Lan needs is a nuclear bomb, otherwise he will not be able to resist the 100,000 elite soldiers of the second prince.

Of course, these are all afterthoughts, and you can get as many as you need now, and you can't rush it.

"Okay, Rick, you take care of Daisy a lot, she will be the Minister of Weapons in the future, she is on an equal footing with you, don't bully her, she will try to meet any requirements."

Luo Lan ordered, and Rick laughed: "I don't dare to bully this little girl, she can kill me with a single bomb." ”

On that day, the weapons manufacturing department was established, and Rick gave up almost all of the blacksmiths to Daisy, and the most elite miners to Dais.

As a result, twelve kilometers north of the Rik Special Economic Zone, the second industrial base - Daisi Special Industrial Zone was established.

In the days that followed, this special industrial zone provided Luo Lan's army and fleet with an endless supply of explosive bombs and rockets, as well as the invincible cannon known as the "black pipe that broke the old world".

The manufacture of gunpowder was on the agenda, and Luo Lan did not leave the Dies District, he deliberately waited here for two days.

He watched the workers go about their work, and then the workers watched as Daisy made gunpowder like a drunkard.

Large earthen kilns were built here, which were used to make earthen pots.

The so-called earthen jar is actually an oval-shaped "ceramic" with a hollow inside and used to store gunpowder.

This is what Daisy has asked to do, and the requirements are very strict, and it is related to the lethality of gunpowder.

Finally, two days later, at dusk, the first bomb was ready, and making the bomb was still easy for Daisy to use.

Half a football-sized bomb with traces of coal burning, already filled with gunpowder.

A bomb of this size is already very powerful, and the explosive force generated by the instant combustion of gunpowder in it should be able to destroy an ordinary city wall.

The iron flakes mixed with the gunpowder will shoot out in all directions, killing more enemies.

Luo Lan looked at the black bomb excitedly.

The workers didn't know what it was, but they were excited, as long as the prince wanted something good.

The test explosion experiment began.

As Daisy had ordered, Barrett shoved the bomb under a large rock, exposing only the fuse from the mouth of the earthen jar.

Then, in the limelight, Barrett lit the lead.

The fuse immediately burst into flames and quickly burned into the bomb.

After a few seconds of silence, the bomb exploded with a bang.

The boulder was overturned, and the stone, which was taller than Barrett, flipped back a few times, revealing a large black crater.

Barrett also flipped over, and he was caught off guard and fell to the ground with a loud bang, falling into a mouth full of mud.

The workers in the distance screamed in fright, and their faces turned white.

Rick laughed loudly, and Bina excitedly took Daisy's little hand.

Only Luo Lan was the calmest, and he was even a little too calm, or rather, Luo Lan was a little disappointed.

"Why is the power so small?"

This is Luo Lan's most intuitive question, although the stone is large, it is mixed with coal, so it is not a pure broken hard stone, under the bombardment of gunpowder, it should be broken, at least it should be lifted away.

The result? It was only a few turns, and the huge crater created by the explosion was also very delicate, and Luo Lan clearly saw the still hard rocks in the pit.

If it was just this kind of power, I am afraid that ten explosive bombs would explode at the same time to blow up the rock.

"Isn't the ratio of raw materials wrong? The formula for the ratio of black powder seems to be one sulfur, two nitrates, and three charcoal. ”

Luo Lan said to himself, his mantra itself is actually not accurate, and the real proportion is difficult to do, but under the current conditions, it is also possible to achieve one sulfur, two nitrate and three charcoal, and then improve it.

Also, the purity of the raw material can also seriously affect the power, Dais's saltpeter and sulfur are natural, and she has only been simply purified, which must also affect the power of gunpowder.

In short, it was not easy to make powerful gunpowder, and there were so many things that needed to be improved, and Daisy and her father had clearly not done that yet.
