Luo Lan was a little disappointed.

However, the workers and guards around them were already cheering, especially after Rick explained: the blaster can be used to blast through the rocks, and we can go find the gold!

This sentence made everyone ecstatic, as if everyone had found gold.

The blushing Daisy secretly observed Luo Lan and found that Luo Lan was thinking about things very calmly, and the prince was not excited.

Daisy's heart tightened, and her lips pursed slightly.

Bina, who was also looking at Luo Lan, also discovered this situation, she signaled everyone to calm down, and then patted Luo Lan: "Hey, Prince Luo Lan, what are you doing in a daze?" ”

Luo Lan came back to her senses and smiled at Daisy, "Daisie, the explosive bomb you made is great, is it even more powerful?" ”

More powerful?

Not to mention Daisy, even the workers felt that Luo Lan was talking in her sleep.

The people here have never seen a bomb except Daisy, and now that they have seen it, they are shocked, and they are already going to be sluggish, where will they consider being more powerful?

"Your Highness, are you too greedy? A little girl has finally built such a powerful weapon, and you are not satisfied, seeing that she is sad", Barrett was the first to fight.

When everyone looked at it, Daisy really looked lost.

"I'm satisfied, but I personally think it can be improved, Daisy, Bina, Rick, you three come here," Luo Lan explained, leading the three of them to the side to discuss.

Rick was the first to speak: "Your Highness, this kind of power is already very terrifying, don't embarrass Daisy." ”

Rick thinks it's okay, this blaster is enough for mining.

Bina looked at Luo Lan in confusion, thinking of Luo Lan's original ridge cultivation method, Bina couldn't help but say, "Do you have a better way to make gunpowder?" ”

The three of them all looked at Luo Lan fixedly.

Luo Lan squatted down and used three piles of small stones as saltpeter, charcoal, and sulfur.

"Look, Daisy, this pile is saltpeter, this is sulfonite, this is charcoal, and my ratio is one to two to three."

Luo Lan began to explain according to her limited knowledge, and Rick and Bina looked dazed, only Daisy had a different color in her eyes.

She sat down and looked at Luo Lan like a good student.

"I've met the master alchemist before, he told me. The power of a gunpowder explosion depends on purity, and there are two kinds of purity, one is the purity of the raw material, and the other is the purity of the proportion, or the accuracy of the proportion. ”

"Well, my father also said that saltpeter and sulfur have impurities such as dirt in them, so they are impure, and I can't improve the purity, but the ratio can be changed, and it can be changed now."

Daisy seemed to wake up suddenly, and ran to the side of the clay kiln with a puff of smoke.

A group of people looked around her again and gave her a hand.

Since there are ready-made ingredients, it is simple to change the proportions.

In Luo Lan's proportions, Daisy reloaded a blaster with the help of workers.

By this time it was already dark, and the guards lit their torches.

Luo Lan didn't talk nonsense and let Barrett try again.

Barrett was a little nervous this time, as this blast bomb was an improved version and could be more powerful.

The rest of the people were also nervous, especially Daisy, who was in a cold sweat.

Eventually, Barrett ignited the bomb that was back under the rock. As soon as he lit up, he turned and ran, ran for a few seconds, and there was a loud bang behind him.

It was a loud noise, like thunder on the ground, which made people's eardrums hurt.

Quite a few screamed and covered their ears.

In the dark night, the boulder was blown away and disintegrated in mid-air, splitting into countless small stones. The smoke did not disperse, and the ground seemed to tremble.

Luo Lan grabbed a torch and ran to the edge of the pit to check, and this time he finally laughed.

The rock has finally cracked! Although the depth of cracking is only five or six centimeters, it is already a big improvement.

Everyone also reacted, and ran over to check, looking at the rubble all over the ground and the huge pit, everyone's mouths couldn't close.

This time the bomb was more than ten times more powerful than the last one.

"Too ...... It's horrible......"

"Your Royal Highness, are you a god?"

There were gasps all around, and the explosive bomb improved by Prince Luo Lan was already a weapon of mass destruction in this era.

Shy and excited, Daisy looked at Luo Lan with admiration on her face, she never expected that Luo Lan also knew gunpowder and was so good at it.

However, Luo Lan was still not really satisfied.

"The power can be even greater, Daisie, while you are making explosive bombs, you can consider purifying, saltpeter and sulfur must be purified." Luo Lan looked at Daisy passionately.

Everyone couldn't understand this, but when they heard Luo Lan say that it could be even more powerful, they were all dumbfounded.

Luo Lan ignored the rest of the people, and he dragged Daisy to the place where the saltpeter was stacked.

Daisy looked at Luo Lan curiously, not knowing what Luo Lan wanted to do.

Luo Lan picked up a piece of saltpeter and said, "Daisi, your father must have thought of a method of purification, but the principle is not right." ”

Luo Lan struggled to recall the high school chemistry knowledge she had forgotten.

"A lot of the way to purify minerals is to change their form and then filter out their impurities. For example, this saltpeter, when it is solid, we can't purify it, but if it is heated in water and saturated and dissolved, most of the impurities can be filtered out, and the rest is relatively pure saltpeter. ”

Luo Lan said with a straight look, and Daisy was a little confused when she heard it, because there were too many professional terms.

"Your Highness, do you mean to put saltpeter in water and heat it? And then what? ”

Daisy is cute.

"Then filter, the soil is insoluble in water, but the nitrate is soluble in water, we filter out the soil, and the rest is pure saltpeter after cooling."

Luo Lan still understands this simple principle, Daisy blinked her beautiful eyelashes, and let out a sigh after half a sound.

"Do you understand?"

"Probably understood, I'll try."

Daisy still blinked, because it was too difficult to understand, she couldn't help but maliciously sell cuteness.

Luo Lan said again: "Sulfonite should also be able to be heated and filtered, but the temperature demand is much higher, you said that you can use pyrite and blackstone to make sulfonite, then the equipment requirements can be met." We have time, you try slowly, human and financial resources are allocated to you, be sure to pay attention to safety. ”

That's all Luo Lan knew, and he had already hollowed out his mind. The specific implementation still needs to be done by professionals, and Daisy is undoubtedly a professional, she has learned a lot of basic skills from her father, but there is a lack of theoretical guidance.

Luo Lan guided her theoretically, she could try a better purification method, after all, the technology of purifying gunpowder raw materials was available in the Tang Dynasty, and the process at that time was not much stronger than that of the Norlan Continent.

"I will work hard, Your Royal Highness, please rest assured."

Eventually, Daisy cleared her mind and became energetic.

In the days that followed, Daisy instructed workers in making explosive bombs and researched purification techniques, and the industrial base on the north side of the West Coast was busy.

Luo Lan stayed for half a month before leaving, because he was a little worried about Daisy, and he left the West Coast after confirming that Daisy's equipment was safe.

This time, Bina did not return, and she temporarily served as the tax collector of the Special Administrative Region to stay for a while longer.

Of course, Luo Lan didn't come back alone, he brought back ten carts of explosive bombs.

Hundreds of bombs were fixed in carriages, wrapped in soft sheepskins, and carefully escorted by the Guards to Phuket.

These bombs were completed in half a month at the Dess Industrial Base. There are more than 100 explosive bombs, which is a lot, but it is still too little for Luo Lan's grand hegemony, and before Luo Lan left, Daisy told him a more serious problem.

"Sulfonite is getting harder and harder to find, and it would be nice if there was a volcano."

The meaning of this sentence is that the production of explosive bombs is about to decrease, and the raw materials can no longer support it.

Luo Lan was still quite depressed, just like being in the mood to eat but getting stuck in her throat by a fish bone.

But for the time being, we can't, we can't attack the southern state and occupy the volcano.

Back now, Phuket City is bustling with people, and thousands of workers are digging pits in full swing.

Luo Lan glanced back at the ten carriages behind him and waved his hand towards the city.

"Barrett, transport the bombs to the palace, the toilet bombing campaign is about to begin."
