Nitrate is added to asphalt and gasoline, which is then churned into a paste.

"Headmaster, this thing will precipitate, although slowly, but it will still precipitate."

The one who spoke was a soldier from the miscellaneous barracks, a worker from the repair shop that Zhang Sixing had collected after he withdrew from the Sixing warehouse.

Initial Chinese level, seventeen or eighteen years old. Fortunately, after inquiry, Zhang Sixing knew that he was learning "new learning".

Compared with the Manchu Qing Dynasty, which only focused on the study of poetry and literature, the later new schools added education such as physics and chemistry.

However, it is worth noting that there are not many people who can go to school in the new school. After all, peasants who pay more than 63 percent of their income in more than 160 kinds of taxes and fees cannot afford to send their children to new schools.

Although I only studied junior high school, I still have a higher level of education than others. It is that after the asphalt and gasoline are mixed and mixed, they will gradually precipitate, which cannot meet Zhang Sixing's requirements.

Looking at the boy who was only seventeen or eighteen years old, Zhang Sixing asked,

"What's it called, how old is it?"

The Speaker ...... Principal, my name is Ding Yidong, and I am ...... I worked in the repair shop for two months. ”

Zhang Sixing understands that the initial Chinese is in this era, but it is an incredible academic degree. After all, at this time, 80% of China was illiterate, and it was a great treasure to find a junior high school student.

"Okay, the old tobacco pouch Xiaoding will join the craftsman group in the future and add an egg every day."

"Yes, Headmaster."

Hearing Zhang Sixing's arrangement, Ding Yidong's eyes lit up excitedly.

The umbrella school is better than other troops, and the minimum military salary and military rations are paid in full and according to the distribution. In addition, Zhang Sixing stipulated that the artisan group of the logistics camp needed to eat nutritious meals.

It is not possible to supply them with a large supply of meat for the time being, but each artisan can eat two more eggs a day.

It's useless for others to envy them, it's for the veterans of the craftsmen in the barracks. For example, among carpenters, those who know mortise and tenon technology or glue paint technology will become craftsmen.

Zhang Sixing has always agreed that China can do without the best businessmen and the best politicians, but it cannot do without the best scholars. As for politicians, they have to be good at getting benefits back from the outside.

Only in China, Zhang Sixing looks down on it.

It's a pity that under the chairman, this matter is very helpless. A soldier should have more than half a politician, and a businessman should have more than half a politician. As a result, these two halves of hanging buckets of water will only snatch benefits from the country, and most of them will go around when they see foreign adults.

"Sir, this is a burning mouthpiece, we have tried, and the gunpowder will not burn out."

Of course, the nozzle was processed by Li Youtian, an old tobacco pouch, according to Zhang Sixing's order, and the ground staff of the Third Brigade tried to process it.

On the field airfield of the Third Brigade, the most satisfying point for Zhang Sixing is that relatively speaking, there is no shortage of steel here, especially a large number of people who know how to process.

It's a pity that Germany is now stepping up its preparations for war, and it is not easy to find good engineers. However, Zhang Sixing had already asked Yelena to choose among the Jews who had fled to Shanghai.

After all, many of them escaped from Germany, and Yelena, a variety of literate people, has been collecting, registering, and organizing to learn Chinese systematically.

Maybe they can't be university professors, but they can be teachers of "junior high schools".

These are all later words, but now with the help of the mechanics of the third brigade, Zhang Sixing's home-made weapons used on the battlefield have been upgraded.

For example, RPGs don't actually have much technical content, otherwise a bicycle repairer in the Middle East can build it. After the shells of the gasoline barrel cannon were upgraded, the firing range reached six hundred meters.

In fact, it is to completely turn the large-headed bullet of the gasoline barrel cannon and the warhead of the round vertebra and cylinder into a streamlined shape. Then a bottom exhaust was added to the tail section.

To put it bluntly, after the large single-headed bomb of the gasoline drum is launched into the sky, it can also spray high-temperature air flow backwards like a rocket. The gunpowder used to make rockets has now become granular gunpowder with higher combustion efficiency.

The precipitation phenomenon that Ding Yidong just discovered was a kind of cannonball used in the gasoline barrel cannon.

Its materials are gasoline, asphalt, nitrate, and white phosphorus, perhaps it can't be compared with the napalm of the United States in the future, as for the power, who has never seen the use of asphalt to clean pig hair.

PS: I may not see it in the future, and I am not allowed to slaughter the second senior brother without authorization, hehe.

"Try this thing again, try whatever tung oil, vegetable oil, etc. you can find, and see if that kind of thing is added, it is best if it does not precipitate."

But these are not the most important equipment, the most important equipment is the most surprising after lunch, a few tailors from the city, and a few painters.

"First of all, the white silk is dyed azure, and secondly, you paint Lao Tzu the color of an eagle, and after painting it with oil, you can still see water."

What is this exquisite, several painters looked at each other. However, the one who has a gun this year is the uncle, and this uncle still has a lot of their wages, which is the best.

However, the principal of the family said clearly, if the painting is not like it, the money will be deducted, and the painter will be serious and responsible when painting.

On the white silk framed with a wooden frame, several painters took large brushes and started painting seriously.

As for the cut, what they had to do was very simple, according to the delta wing that Zhang Sixing flew out of the Sixing warehouse, expand the area enough, and make a new delta wing.

In the case of delta wings, increasing the area is increasing the load, but that doesn't end there.

Zhang Sixing had to think of some new ways to make the frame, he didn't have so much dura aluminum (the aluminum used to build airplanes). And I'm afraid I can't find that thing in China, and even if I do, there is no corresponding processing tool, which is a bit of a test of his creativity.

Around this time, there was no glass cloth or chemical resin to be found in China. But if there is no corresponding material, I am afraid that his bet will be lost.

What kind of material should be used to make a pipe with high strength?

With a lot of thoughts, Zhang Sixing left the miscellaneous barracks, but in a blink of an eye, he found inspiration.

"Duan, Duanping, in the future, we will use the big knife that the principal gave us to cut the devil, and if the knife is not good, it will be a shame to go into battle. We revolutionary soldiers, what kind of hardship can't be endured, how can we be willing to put on a white wax pole. ”

The toughness of the ash rod is good, and it can not be strengthened with silk. The toughness of silk is not as good as that of glass cloth, but we don't have it.

It's okay to try, it can't be too thick anyway, if the thing is too thick, the resistance will be too great, and it won't be able to fly too far.

Thinking about what he didn't have, a plan for a night attack had been formulated by Zhang Sixing.

And the night attack happened tonight, because the robbery he encountered during the day made him a little angry.

It has always been Lao Tzu who has changed the law to rob other people's things, and today there are people who dare to break ground on Tai Sui's head, and they can't spare anything if they say anything.
