Hire a miner, even if the other party is working hard, waving the iron manuscript whirring.

Coupled with good fortune, every pickaxe was dug into the veins.

At the end of the day, I was exhausted, and at best I could only dig up a few baskets of ore.

However, if gunpowder is used, a large amount of ore can be easily blown up.

All the miners have to do is clean up the mess.

Pick out the required ore for shipment.

The stones and dirt that are not needed are transported to a place that is out of the way.

A miner can earn anywhere from thirty to one hundred dollars a day.

After all, some pits are paid according to the amount of ore produced.

Some "model workers" are possessed by the European Emperor, and digging up some more in a day may be able to reach Qin Fan's income level.

For a gunpowder, the raw materials needed are saltpeter, charcoal, and sulfur.

Among them, its cost is originally inferior to the wages of miners, but the effect is indeed difficult to achieve for ten miners!

It's a coincidence.

A few days ago, when Qin Fan sent a microscope to Sun Simiao, the other party was writing a book.

He watched from the sidelines for a while.

In the subsequent check-in that day, I was given the method of making explosives and gunpowder, including black powder.

Qin Fan only learned afterwards.

The book that Sun Simiao wrote that day was called "The Danjing Inner Sulfur Method"

Among them, there is a sentence "one nitrate, two sulfur and three charcoal" that has been widely spread in later generations.

"I've heard of this gunpowder a little, but it seems to be uncertain, and there is no way to control it!"

Li Shimin's face was worried.

"If the ore is blown down, and the miners are folded in it, it will not be worth it."

Qin Fan nodded matter-of-fact and said, "Yes, the detonation does need to be calculated and measured. ”

"But the power of that gunpowder is actually controllable!"

"The reason why Danshi alchemy is uncontrollable is because they don't know why it will explode. @精华\/Shuge*First Update~~"

"If they knew it would explode, most of them probably wouldn't have used these raw materials."

"The power and stability of the explosion mainly depend on the ratio of various materials in the gunpowder."

"Of course, this refers to the original black powder. After black powder, there are many other new types of explosives, but those, in their current state, there is no way to make them! ”

In fact, the substance required for a more powerful explosive, such as N, must be chemically extracted.

As a result, it was necessary to set up a chemical laboratory, make glass containers, and so on.

It can be seen that the modernization of Datang has a long way to go!

"Can this gunpowder really be controlled?" Li Shimin was surprised.

"Boss Li might as well go out of the city with me for an experiment."

Hearing this, Li Shimin was stunned.

"Isn't it okay to experiment here?"

"Here?" Qin Fan was also a little surprised.

"Didn't Brother Qin just say that he could control the power? Since the power is controllable, isn't it okay to test it here? ”

Li Shimin said.

Hearing this, Qin Fan was helpless: "This power is controllable, but the sound can't be controlled!" ”

"Once the explosives are ignited, the sound is loud enough to reach the palace. You don't want the whole Chang'an City to notice us, do you? ”

Hearing this, Li Shimin patted his head: "It's not appropriate to do this." ”

"It's not just inappropriate, if the people think that the earth dragon has turned over, maybe something will happen, and then it will cause a riot in the entire Chang'an, and you and I will not be able to escape the blame."

Li Shimin also said with a lot of trouble: "Then let's go out of the city!" ”

"Okay, you wait for me, I'll fetch the gunpowder."

Outside Chang'an City, Li Shimin watched Qin Fan put a piece of bamboo tube in his hand on the ground, and then fixed it with stones.

"This is gunpowder?" Li Shimin wondered.

"That's right, the conditions are rudimentary, and you can only use bamboo pipes. Here's the lead, just light the ......"

Hearing this, Li Shimin took out the fire fold and put it next to the lead.

"What happens if it's lit?"

"Run. (This chapter is not finished!) )

Chapter 140: Gunpowder, I'm Not Dead?

！ ”

Qin Fan dragged Li Shimin past him and ran out of a distance of forty or fifty meters before turning his head to look.

Li Shimin was coldly dragged away.

While panting, he wondered, "Brother Qin, what are you doing here?" ”

However, the voice did not fall.

"Bang!"

A loud bang came from behind him, followed by a splash of rocks.

Qin Fan stretched out his hand, reached out to take off the saber, and knocked a few small stones flying towards the two of them.

"Looks like we're going to have to run a little farther."

said, looked back at Li Shimin: "Lao Li, don't be so reckless in the future, it's not too late to wait for me to finish speaking!" ”

Li Shimin was still in place.

"Lao Li?"

Qin Fan couldn't help but stretch out his hand and turn around twice in front of Li Shimin's eyes. Initial Update@

After a while, Li Shimin came back to his senses, looked at the smoke billowing in front of him, and said with a happy face:

"If Brother Qin hadn't pulled me just now, I might have ended up with this gravel."

Qin Fan glanced at him: "Do you think you are copper-headed and iron-clad?" ”

"If it explodes at that distance, I'm afraid that it will already be shattered, and I won't even be able to leave the whole corpse!"

Li Shimin also nodded and said, "Fortunately, there are Brother Qin." ”

Immediately, he frowned again and said, "It's so powerful, I'm afraid it's too dangerous to use it for mining!" ”

Hearing this, Qin Fan scratched his head:

"Isn't this the first time I've shown it, and I want to give you some excitement?"

As he spoke, he took out a slightly smaller bamboo tube from his sleeve, and fixed it in the same way five meters next to the explosion just now.

Then ignite the fuse and slowly retreat.

This time, without Qin Fan's pull, Li Shimin consciously ran fifty meters away.

Then, he looked at Qin Fan, who was only twenty meters away, and couldn't help but say urgently:

"Brother Qin, run away, you will be caught up there!"

Qin Fan smiled and said, "You can see it more clearly here!" ”

Li Shimin was in a hurry, gritted his teeth, and turned back to pull Qin Fan away.

But he had just grabbed Qin Fan's hand.

"Bang!"

Li Shimin's eyes were closed, and there was a burst of despair in his heart.

I didn't expect that I was famous and in my prime, and I was folded outside Chang'an City!

Goguryeo has not finished fighting, and Changle has not yet married.

The huge national debt still needs to be repaid, and the caravans for sea trade are still being built.

And the Tibetan, the ......

Too many regrets.

Too many ambitions to be accomplished!

Suddenly, a sentence made Li Shimin's remembrance come to an abrupt end.

"I didn't expect you kid to be quite righteous!" Qin Fan couldn't help but sigh.

Hearing this, Li Shimin slowly opened his eyes.

"I ...... Ahem, I'm okay with this? ”

Li Shimin stretched out his hands, flipped back and forth, and turned around in place again.

I found that I was unexpectedly unscathed.

Immediately, he set his eyes on Qin Fan again.

Qin Fan also stood in front of him with all his beards and tails.

I thought that I would be like what Qin Fan said, that is, I didn't have a full corpse when I died.

But why is it like this now?

Li Shimin couldn't help but cast his puzzled gaze on Qin Fan.
