In the Ordnance Prison, Zhu Changhao feels like teaching chemistry to junior high school students, the problem is different from the chemistry class in the 21st century, Zhu Changhao does not have too many theoretical interpretations, what hydrogen, helium, lithium, beryllium, boron, carbon... There is no such thing as a relative atomic mass, and there is no periodic table or anything like that.|For every two people who look at romance, there is an account that has registered for the network. ≥, it is hands-on practice directly, and without too much explanation, it is directly named, what is made from saltpeter is called nitric acid, and what is made from sulfur is called sulfuric acid.

Now, Zhu Changhao will be that gray thunder. The solution of mercury was called thunder acid at the beginning, and the reason was, "You see, this gray powder that this king extracted and filtered out of this thing, and when it hits, it is like thunder, so this liquid is called thunder acid." ”

Through a series of experiments, little stars began to emerge in everyone's eyes, they felt that Rui Wang Ye was a god, from some potions (they consider nitric acid and sulfuric acid to be poison potions) can refine explosive thunder, which in Taoism, are Ge Hong, Ge Tianshi and other immortal cultivators have become successful warlocks, and warlocks can refine some magical things.

Next, Zhu Changhao asked people to find a wooden barrel of fire oil from Qingyang Mansion, made a bowl of oil (fire oil), poured it directly into a translucent glass cover, and then inserted a snorkel into the sink to start fractionating the oil oil.

In the alcohol lamp, which was fueled by the knife wine, everyone began to pay full attention to the changes in the oil of fire.

The oil was layered in a translucent glass cover with considerable changes to the naked eye, and the first layer of the oil was ignited directly on the outside after passing through the guò sink.

Next, Zhu Changhao let the fractionation glass cover slowly cool down, almost half an hour, uncovered the cover, pointed to the liquid in it and said, "Well, everyone, please see, the gas that can be burned when it was poured into the sink just now is thermal oil and gas, of course, you can also call it petroleum gas." ”

Speaking of this, everyone began to look at the conduit in the sink, but Zhu Changhao didn't care what they thought, but continued to point to the liquid in the crucible and said, "The one above is very light, it is gasoline, the one with a slightly darker color in the middle is kerosene, and the one below is brownish-yellow, this king will call it diesel, and now, use a bucket scoop to separate them." ”

After saying this, Sun Yuanhua immediately walked to the side and handed the copper bucket scoop to the prince.

Zhu Changhao carefully put kerosene and gasoline directly into a flask, and then filtered the oil residue inside the crucible on a gauze mesh.

Finally, the brownish-yellow diesel is distilled in a crucible that is not particularly sealed.

As a result, an oily, yellowish liquid appeared, and this thing floated on top of the glue-like black oil, and Zhu Changhao slowly cleaned up the oily thing with a bucket scoop, and slowly waited for it to solidify.

Then the glue-like black oil was scraped out of the layer of lard-like stuff on top, and finally the black black oil was filtered again.

At this time, Zhu Changhao pointed to these three extracted things and said, "Ladies and gentlemen, this layer is light yellow, this king calls it paraffin, this second lard, this king calls it engine oil, or lubricating oil, and the black oil that is filtered out at the end is viscous, this king calls it heavy oil, after this black oil is ignited, the temperature is extremely high, and it is attached to things, and the water cannot be extinguished, so we can use this thing as our combustion in the future. Play. Second, this kind of slag is like a thing, called asphalt, Brother Chang Geng, the sole of that asphalt board, it depends on this thing. ”

After popularizing organic chemistry to the people in the ordnance prison, Zhu Changhao was also a little embarrassed, "If you let a person who studies Chinese language and literature teach chemistry, he can only teach elementary chemistry." ”

The matter is basically over, and the last step is the production of the fire cap.

"Brother Chuyang, this copper coin fire cap is too big, and in the future, the fire cap will be made into a soybean grain about the size of a grain of soybean."

Next, Zhu Changhao melted the paraffin wax in boiling water, and then carefully used the four standards of two or eight, three or seven, four or six, and five or five points. Mercury and paraffin are pressed evenly.

In the end, the results were not ideal, and Zhu Changhao immediately asked people to add sulfur powder to the twenty-eight points.

As a result, the proportion of this fire cap was determined, two parts paraffin, two parts sulfur powder, and six parts gray thunder. Mercury has the best stability and sensitivity.

This time the test was completed, and Zhu Changhao made a summary to everyone, "Everyone, today's test, you probably have already understood, but the people present should not tell the results of this test for thousands of years, in addition, these things must be remembered and not wrong." Also, after this fire cap is pressed, it must be sealed with oiled paper sprayed with water and placed in the cellar, do you hear? ”

Zhu Changhao's last stern inquiry, everyone, including Sun Yuanhua and Song Yingxing, knelt down in fear and said tremblingly, "We will obey the king's orders."

"Well, get up."

After everyone got up, they realized that if the prince with a pleasant face was angry, he would be a fierce beast that would choose people to devour.

"As for the Flying Raven of the cone-pillar shell, after this cannonball is fired, it will explode, so the delay medicine line of the projectile must be prepared.

So how do you delay it?

Very simply, in this conical projectile, the medicine line is spiraled with a certain spacing, that is, coiled into a futon shape, so that if the powder in the warhead is ignited, it will take a certain amount of time, and the end of the medicine line has been ignited with a fire cap when it is fired. ”

After Zhu Changhao finished talking about the principle, everyone pondered for a while, only to see a master next to him say, "Lord Wang, this is the kind of meaning we mean to put two kicks in the Lantern Festival, right?" ”

"Well, yes, what's your name?"

"Back to the prince, the little one is called Dai Cang, he used to be the Jiupin Prison Army, and later, because he offended the powerful minister Zhou Daodeng, he was exiled to the Ministry of Works, and in the seventh year of the Apocalypse, he was detained by the prince in the ordnance prison until now."

"Then your family is here, right?"

"Back to the prince, last autumn, the little one had already taken his family to Hanzhong Mansion."

"Okay, you can do it."

Zhu Changhao looked at Dai Cang, who is now in his early twenties, and was very happy, because in history, although this Dai Cang was not very good, he had a powerful son. If he does not change the original historical trajectory, his youngest son will be the famous Dai Zi in later generations. This Lianzhu gun and son-mother gun invented by Dai Zi can be regarded as a wooden warehouse.

When studying the history of the Ming and Qing dynasties in the 21st century, Zhu Changhao remembered Dai Zi and his father Dai Cang.

I can't imagine that Dai Cang is now in his armory, that's a treasure.

Zhu Changhao grinned and thought crookedly. "This time the harvest is really big, not only did I make a cross-era weapon fire cap, but also determined the flying fire crow, which is the prototype of the famous rocket in later generations. Also, a potential talent has been discovered, which is really a three-happiness coming-in-the-door. ”

It's almost time, although it's mid-March now, and it's not as early as before, but Zhu Changhao decided to go back.

On the small pier of the small island in the middle of the river, only Sun Yuanhua and Song Yingxing were the two who bid farewell to the prince, and when they boarded the boat, Zhu Changhao asked by the way, "Brother Chuyang, how is that Dai Cang in the ordnance prison?" ”

"Back to the prince, this Daicang person is very flexible, and he has a lot of research on Luban techniques and machine techniques, some of the lifting equipment on the island, as well as the water mill construction, are all from this person's handwriting, and the steam engine that is being studied now has made progress, and this person is responsible for doing the work."

"Well, that's good, promote this person in the future, in the hands of this king, I don't want anyone to be buried."

"Yes, Lord Wang, Weichen obeys."

Taking advantage of the afterglow of the setting sun, Zhu Changhao returned to the carriage, hungry, and drove towards the Ruiwang Mansion in Hanzhong Mansion.

In the Baxi Palace of King Rui's Mansion, the ladies have already finished eating, and at this time, six women (including the little girl Liu Ruyi and her goddaughter Zhu Yiyi) are playing together, trying on the cheongsam and bra.

Zhu Changhao stopped the salute of the guards outside the palace, and quietly touched in, a fragrant spring. color, almost made him forget the feeling of being hungry.

Quietly touched it, and a handful of it surrounded a woman who was scratching her head.

After all, looking at the back, coupled with the sudden attack, Zhu Changhao didn't know that the woman around him was water, he only felt that his figure was very material, and his palm pressed against a soft, delicate, and elastic towering place.

Just when a scream was about to come out, Zhu Changhao covered her mouth and nose with his left hand.

This sudden change made the remaining five girls a little stunned, and when they looked at it again, it was the prince.

The fifth girl was about to salute, Zhu Changhao hurriedly stopped, and pinched the towering place with his right hand, and an inaudible moan squeezed out of his mouth.

Hearing this moan, Zhu Changhao let go, and naturally knew that it was no one else in his hand just now, it was Qiao'er.

Qiao'er also knew from the expression of her sister just now that the man who pinched her baby was not someone else, but the prince she had been thinking about for a long time.

In front of the sisters, she was teased by the prince, and she was light, and Qiao'er actually had a kind of excitement in her heart. Feel.

She even thought that it would be nice if the prince's hand was stronger, or that it would be more exciting to hit someone's ass with his huge palm......

Qiao'er Tianma starry sky fantasized, and suddenly realized that she was a little too embarrassed to think like this, too much, is she a woman?

No one gave Qiao'er an answer, and there would be no answer, because Qiao'er would not tell her sisters about such a shameful thing.

And in the eyes of the sisters, no one has to say disgust for what the prince did just now, after all, Qiao'er is the princess's dowry girl, then in the future, it will be the princess's maid, no status, as long as the prince needs it, she wants "that" woman, if she gives birth to a son and a half daughter in the future, she can also be crowned the princess on the side.
