"This is the black powder explosives you said OK ......?" He Zilong pointed to the drizzle, and there were a few black lights, a bit like firecrackers, but the second half of the power directly dumbed the fire of a small bamboo tube, and looked at the captain speechlessly.

"This, Mies Cow and I are doing our own separately, maybe the waterproof is a little worse, I'll improve it immediately......" There were some cold beads of sweat on the white captain's forehead.

He Zilong didn't say anything more, but opened his thing, took another sample, and compared it. Suddenly I knew what the problem was, why was this formula different from what I imagined?

Maybe it's because foreigners think differently, or do they get a different formula, messy and self-righteous modifications?

Of course, it seems that this situation is not incomprehensible.

As we all know, gunpowder was invented by the Chinese. But if you ask further which Chinese invented it, I'm afraid no one can say clearly. Judging from the historical data, at least three people are considered "suspected inventors".

The first was Ge Hong, a native of the Eastern Jin Dynasty. According to the "Jin Shu Ge Hong Biography", Ge Hong is a famous alchemist and pharmacist, and has written a lot in his life, including the inner and outer chapters of "Hug Puzi", "The Legend of the Immortals", "Behind the Elbow" and so on. It is said that he invented gunpowder, based on the phrase "using saltpeter stone as water is condensation" in his "Bao Puzi Inner Chapter".

The second is Tao Hongjing, a Liang man of the Southern Dynasty. According to "The Biography of Tao Hongjing in Liangshu", like Ge Hong, Tao Hongjing is also a famous alchemist and pharmacist, and is the author of "Commentary on the Materia Medica" and "True Spirit Position Karma Map". "Materia Medica" records: "If you hold salt and snow without ice, if you burn it strongly, purple and green smoke will rise, and it will still turn into ashes." Constantly boiling like simple nitrate, the cloud is real saltpeter also.

The third is Sun Simiao, a native of the Sui and Tang dynasties. There are biographies of Sun Simiao in the old and new "Book of Tang", he is a famous alchemist and pharmacist in the Sui and Tang dynasties, and has the reputation of "King of Medicine", and is the author of "Qianjin Yao Fang", "Qianjin Yifang" and so on. In the process of alchemy, Sun Simiao mixed sulfur, saltpeter, and charcoal to make medicinal powder, isn't this medicinal powder gunpowder?

In Chinese history, there are also stories caused by foreigners coming to China to steal the formula of "black powder". It's just that it's hard to say which formula was stolen, and after it was transmitted back to their country, after so many years, I'm afraid that the textbooks should only be told about history, after all, the current explosives are not black powder for a long time, maybe the record is wrong?

After all, with TNXXX the explosive power is 14 times that of black powder, and nitroglycerin is 16 times. Six or seven tons of high-purity black powder is equivalent to one ton of ordinary explosives! Even abroad, there are not many people who study black powder!

He Zilong opened the explosives barrel of the captain Lao Niu again, and found that there was also some deviation.

"I'm still used to using the local method of my hometown as an example, my dad used to make his own in the countryside, fried wild boars, or used as funeral ceremonial flowers......" Lao Niu touched his head and replied with a smile.

This answer was only very down-to-earth, and He Zilong remembered that the people in his hometown were the same.

What's more, in these days, basically the elderly and middle-aged people have not read much, and those who have studied elementary school are considered intellectuals among the older generation. There are many people who can't even write their own names!

In fact, even in 2017, data from the National Bureau of Statistics showed that there were still more than 60 million illiterate people in China. And in the nineties, this data is not to be said, because it is extremely scary to think about it!

If the 60 million people in 2017 were a country, it would be the 24th most populous country in the world, the same as the entire population of Italy and 2.5 times the population of Australia.

In other words, 1 in 20 adults is illiterate. And in the nineties, it was probably one in three people!

Many people believe that the majority of illiterate people are currently elderly, and that the illiteracy rate will only go all the way down as a large number of elderly people born before the founding of the People's Republic of China die. In fact, this is not the case: as far as He Zilong knew before his rebirth, the illiteracy rate did not go all the way down, but fell to 4% and then repeatedly.

The reason for this is that many views on the uselessness of reading have arisen in later generations, which has influenced many generations of wage earners.

As a result, on the one hand, there are millions of first-line school district houses, and on the other hand, there are a large number of rural semi-literate people who cannot afford to read. Actually, it's quite helpless to think about it!

Therefore, the black powder that Lao Niu is making now is a bit like that, which is actually understandable.

"You can't do this, come, I'll change the proportion of your formula, if you want to do this, ...... like this" He Zilong still took the initiative to help them change the formula, in fact, it is not a change, but a change in the proportion.

Because no nitrate ore has been found nearby, the nitrate that has been saved these days has actually been collected by He Zilong for hundreds of his subordinates to be fixed in one place for convenience.

These are not many amounts, so there will not be much explosives to be made.

The black powder that comes out under the correct formula is not too much to worry about drizzle and moisture. Just pay a little attention to the packaging, the only thing to worry about is whether it will explode early when it gets wet, which is a problem.

Just like He Zilong's hometown, there was an accident before.

The warehouse containing dozens of tons of black powder exploded, shattering the glass two kilometers away, and the cause of the explosion was that the black powder was damp. It's also drunk to think about!

Therefore, sometimes fire and theft prevention must be prevented from moisture.

(The principle is that black powder becomes hot when it is damp, and it contains substances with low ignition points, such as magnesium, and the energy accumulated on the surface makes the temperature reach 40 °C, which may spontaneously combust and cause an explosion.) ）

Because of the impurities of the material, after He Zilong re-matched, he found that the material in his hand only weighed more than one kilogram.

"How do I feel, it's more like a soil grenade......" He Zilong looked at it, and wanted to complain a little.

During the Anti-Japanese War, the grenades manufactured by the Eighth Route Army had a very limited pass rate. The standard weight of a grenade is 750 grams, but the self-made explosives of the Eighth Route Army are not pure, and the quality of the clad iron outside is poor.

The Japanese army's sweet potato grenades, each weighing only 500 grams, are small in size, and an infantry can carry 6 pieces. The design and production quality is good, and it can produce at least 15 fragments in one explosion, with a killing radius of 12 meters, and can often blow up a piece when thrown into the charging formation.

"Go away, I'll try a few times......" He Zilong said to Lao Niu and the captain, and the latter two ran away after hearing it.

The first throw, it didn't blow up, He Zilong felt a little unbearable on his face.

The second throw, thanks to the Buddha, exploded, and the bang was enough, and He Zilong almost fell down in time, because the explosion time was not easy to control at all. Of course, there is a solution, that is, don't do it to death, throw it away.

After throwing a few more attempts, I found that the explosion rate was only 50%, but the ones that exploded were effective enough, and the explosion power was only two-thirds of the power of a regular grenade.

"Just follow this modification, 50% of the explosion rate is enough, about a kilogram is also the limit, anyway, it is also those indigenous warriors who throw it, it is not a problem to let them throw it farther, we pay more attention when we throw it. If it were yours, it would either not explode, or it would be more like a mine, or an uncontrollable timed explosive......" Touching the dust on his face, He Zilong said.

The captain and the old cow glanced at each other thoughtfully, and then nodded heavily.
