Ha ha! I'm going to hang up!

After these days, the generals in the tent have become accustomed to Qin Feng's strange way of speaking. Pen, fun, pavilion www. biquge。 At this time, Maha and Ashiwa were thinking about something else.

Own! The general just said that the account is all his own people! Ha ha! That's a lot of talk! This sentence of his own people shows that in the general's heart, the two of them are completely different from Shamoro! Although the three of them were like themselves, they were under the orders of the general. But in the eyes of the general, they are outsiders, and the two of us are our own people! Ha ha! Own!

Muromaha asked excitedly, "General, what are you going to build?" Can you break through the city of Kanzaro in one fell swoop"?

The other generals also looked at Qin Feng, very curious in their hearts about what this powerful thing Qin Feng said, what is it?

Qin Feng deliberately sold a pass, and did not answer directly, but turned his head and asked Li Quai: "Lord Su Shi, can our army have saltpeter, sulfur, charcoal and other things"?

"General, the production of saltpeter and sulfur in the land of Tianzhu is quite large, and there are many of them in our army, which are used as fires on weekdays. As for charcoal, although there is not much in stock, it only takes a day or two to burn it now, and that is how much it takes!"

Ha ha! God help me! You must know that in ancient China, saltpeter and sulfur were hard to come by, and even if they could be mined, the cost was huge! Qin Feng never expected that in this land of Tianzhu, saltpeter mines and sulfur would produce quite a lot. Such fertile land, such abundant products, if you don't make good use of it, wouldn't you be sorry for God's love for you!

Qin Feng put his mind at ease at this time, and laughed and said: "Everyone, next we have to try to make black powder, as long as this black powder is completed, let him take the city of Salo and then the city is high and deep, and in a moment, I will also let it turn into powder and ashes!"

Next, Qin Feng briefly described how to make black powder, the use of black powder and its approximate power.

The generals were shocked when they heard this, according to what Qin Feng said, this black powder not only destroys the withering and decaying, shakes the heavens and the earth, but also overturns the giant city, like a piece of paper! Is there such a powerful thing in the world? Can such an earth-shattering power really be created by manpower? Isn't this the legendary power that belongs to the gods?

Sima Zhi jumped up directly from the stool and shouted, "Second brother, what you said is true? Is this black powder really so powerful"?

Qin Feng smiled and nodded, and when the generals saw Qin Feng nodding, they all got up and looked at Qin Feng. As soldiers, they know too well what this black powder that Qin Feng said means once it is manufactured!

This means that as long as the black powder is in the hands of the Qin army, any strong city in the world will be nothing more than paper paste in the eyes of the Qin army. In an instant, he can disappear between heaven and earth!

This means that no matter where the Qin army points in the future, the world is so big, no city can block the way of the Qin army!

This means that the Qin army is thousands of miles eastward, as long as there are no major mistakes, it is difficult to fail with the strong combat power of the Qin army and the huge destructive power of this black powder!

To say that when he was in Qin City, it was Qin Feng who instigated hundreds of thousands of Qin people with his clever tongue, igniting the great Qin dream hidden deep in the blood of the Qin people!

In Bolun City and Harappa City, Qin Feng used one victory after another to let the Qin people really see that this almost ridiculous Great Qin dream has the possibility of being realized!

So now, Qin Feng has used the epoch-making product of black powder to make it seem as if the Qin people can touch this dream just by reaching forward!

Li Quzhi's face flushed with excitement, and he grabbed Qin Feng's palm and said, "General, you are really an immortal sent down from heaven!" It seems that the last generals have seen the day I entered Xianyang City! It seems that I saw the day when hundreds of thousands of Qin people drank Qin wine and ate bitter vegetables and lamb soup (the ancient name of mutton steamed buns)"!

Speaking of this, Li Quzhi howled excitedly, like a child! The rest of the generals in the tent also wept. Although the generals Maha and Ashiwa are not Qin, they get along day and night, and they also understand what Great Qin and Xianyang mean to these Qin people. Now seeing them all with eyebrows, they hugged their heads and cried excitedly, and they also felt excited, and their eye circles gradually turned red!

Oh, yes! Returning me Daqin and returning me Xianyang, more often in the past, was just a slogan to inspire soldiers to move forward! Among the Qin army, among the Qin people, except for a very small number of people, most of the rest feel that they may not see that day! After all, the Qin people have been far away from their homeland for hundreds of years, and this thousands of miles away has gone all the way east, where will it be so smooth!

But as long as you follow the general all the way to the expedition, even if you can't see it, your children and grandchildren will definitely see that day! I will definitely return to Daqin and Xianyang with my bones! Then I will definitely smile at Jiuquan!

And now it's different, completely different! At this moment, it seems that this dream of Daqin is no longer a slogan, nor is it a dream! Because it's really achievable! You can do it in your lifetime!

Li Quai, who had cried a lot, wiped his tears and said embarrassedly: "Let the general laugh!" You see that the last general is over half a hundred years old, and he is still crying like a girl! ”

After speaking, he looked at the generals in the tent and said, "Everyone, only we know about this black powder. This thing is related to the rise and fall of our Qin army, and it has too much to do with it! Although the old man is not in charge of the punishment of the Qin army, if anyone leaks the slightest rumor, don't blame the old man for being ruthless and ruthless"!

Although the other generals of the Qin army nodded in agreement, they didn't take Li Quai's words seriously. Who would dare to say anything about this big thing? Who will speak out? If you say it, will you still be Qin Jun? Are you still a Qin person?

But at this time, Murumaha and Ashiwa have a different taste in their hearts! On the one hand, Qin Feng said such a major thing in front of the two of them. My heart is grateful and glorified. On the one hand, he was a little afraid, once this black powder leaked out, he was afraid that the first person to be suspected would be himself.

Thinking of this, Muroma and Ashiwaqi fell to their knees, and swore in the five-body blessing: "Immortal Heaven is above, the two of me were born as Qin people, and died as Qin ghosts!" If you give birth to a different mind and leak black powder, you may suffer from the burning of your body, and your soul will never be reborn in the Ganges"!

In the land of Tianzhu, this fire is the most cruel punishment, it burns not only the body, but also the soul of the victim. The people of Tianzhu believe that those who have been burned by fire will have their souls burned forever, and they will never be able to enter the Ganges River to be reincarnated as a human being! In the land of Tianzhu, this oath of burning fire is also the heaviest first-class poisonous oath!

Seeing that the two of them made this poisonous oath, Qin Feng hurriedly helped him up and comforted: "The two of you are serious, you are all Qin people, just like everyone!" I believe in you! Everybody believes in you"!

As one of the four great inventions in China, black powder has played a pivotal role since its appearance. It was first invented by the alchemist Ge Hong, and Tao Hongjing, a pharmacist in the Northern and Southern Dynasties, had a general record in his work "Commentary on the Materia Medica".

Later, after the continuous improvement of the alchemists of the past dynasties, about the late Tang Dynasty, the black powder was officially finalized and produced. It is a mixture of saltpeter, sulfur, and charcoal. This mixture is extremely flammable and quite intense to burn.

In the combustion process, saltpeter is an oxidizing agent, and when heated, a large amount of oxygen is released. Sulfur and charcoal are the most common reducing agents and are easily oxidized. When they are mixed and burned, the redox reaction proceeds rapidly, releasing a lot of heat and producing a lot of gas. If the black powder is burned in a confined space, it will explode due to the sudden expansion of the volume during the burning.

And this is what Qin Feng wants to make - black powder!

The standard formula of modern black powder is: saltpeter 75%, sulfur 10%, charcoal 15%, and in ancient times, because the purity of saltpeter was not high, the proportion of black powder was often more saltpeter.

Therefore, the first thing Qin Feng has to solve now is the purification of saltpeter and sulfur. Fortunately, Qin Jun has the experience of purifying white sugar, and now purifying saltpeter and sulfur, although it is not comparable to modern technology, can also purify saltpeter and sulfur with higher purity.

In this way, under the auspices of Qin Feng and with the assistance of Li Quzhi and others, the Qin army selected a thousand core backbones and opened up a secret place alone. Began to purify saltpeter and sulfur, began to burn charcoal, began to try to make a product far beyond this era - black powder!
