It was hot and boiled, Chu Qing could say he was careful every step.

For reasons that he was not noticeable and was not proficient in making the first production, Chu Qing did not dare to do too much, and only made less than ten kilograms.

If the gunpowder is reconciled, it will be tested whether it succeeds.

The method recorded in "Wu Bei Zhi" is: "...Put a piece of it on paper and burn it with fire, so that the medicine can be removed without hurting the paper."

There are even more scary test methods: "...Put the medicine to hold a penny of a person's palm, burn it, but the palms are not hot..."

These are the standards for detecting gunpowder for muskets during the Ming Dynasty, and the firing speed of gunpowder is checked.

Chu Qing had confidence in his gunpowder, but he didn't dare to test it on his palm, so he chose the first method.

Scoop out half a spoonful of gunpowder and wrap it on paper. Chu Qing took a stick of fragrant water and walked out to the toilet.

In summer, the toilet is always very exciting, and no one will doubt it with a fragrance.

However, Chu Qing didn't go to his own special "consolation room" and wanted to go to the common that everyone used in the northeast corner of the yard, which was very puzzled.

"Isn't this close?" Chu Qing responded to Mu Nianci very perfunctorily and ran away.

"Near?" Mu Nianci looked at the public cottage, then looked at the direction of Chu Qing's yard, as if... the distance was not much different!

Light the incense and spread the paper bag on the ground, Chu Qing transported his luck and let the two come into contact.

"Swish!" The light was blazing and fleeting.

Chu Qing shook the paper and looked over and over again. There was not even a hole in the paper except for a blackened piece.

"Oh!" Chu Qing patted the gray that did not exist on his hand, very satisfied.

There is still a key issue now, shell.

Chu Qing really wanted to make a grenade, but she didn't have time to figure out how the firing needle and fuse work, and she couldn't make a grenade shell in a short period of time.

She couldn't even understand how the smokescreen bomb that Xiaobao's letter mentioned could explode and smoke with a fall.

When Chu Qing was a child, he tried to smash firecrackers with a hammer with his friends. He needed to hit the same point hard several times before it could explode.

This principle is easy to explain. If you smash it with a hammer, the internal energy will increase, the temperature will increase, and reach the ignition point, so that the internal energy will increase rapidly. If it cannot be released in a short period of time, an explosion will occur.

But if it can explode with a drop, the person who fired the smokescreen bomb at Xiaobao would probably be astonishingly powerful?

No matter what, make a twist first, use open flame points, and just treat it as a powerful firecracker.

Finally, she chose to use porcelain bottles as shells.

She only found this one.

The palace maids at home thought the soldiers were sweating heavily and it was not easy to use incense burners when they were hot, so they bought a bunch of cheap incense dew all over the house, leaving many bottles empty.

The shape of these bottles is like a one-handed hammer, a neck that is long with a palm, a belly that is big for tennis, which is easy to hold and looks like a grenade.

Carefully fill ten small bottles of gunpowder, and then start carefully mixing potassium nitrate and white sugar.

Three portions of potassium nitrate and two portions of brown sugar powder, it doesn’t matter if there is no baking soda. Let’s think about that later.

The temperature was still controlled and the fire was simmered slowly. In order not to let Mars rise, Chu Qing used a furnace grate. This was the first time she missed the induction cooker so much.

Soon the powdered sugar softened and was sticky. Chu Qing stirred carefully, and saw the things in the pot drooling. Caramel, come and skewers hawthorn. Dip them into the gunpowder-flavored candied haws.

When the batter turns dark brown, slowly pour it into the small porcelain bottle and insert the twist into it while it has not hardened.

The salt sugar produced was also filled with ten small bottles, which was the "smoke screen bomb".

All the exposed twists were wrapped in red paper, and they still looked like a bottle of sweet dew.

The remaining materials were put into the jar in a category and sealed, and placed in a cool place in the inner room.

Let’s find a place to test the effect first.

After an hour, the salt sugar was completely cool.

"Ah yes!" Chu Qing walked out of the room, "Look at how this is?"

Chu Qing handed the small porcelain bottle to Zhuo Yao: "Let the fire like a firecracker."

Zhuo Yao did as he said, lit the twist and ran away, then covered his ears.

I saw a lot of smoke emitting from the small porcelain bottle.

"Why didn't it sound?" Zhuo Yao was puzzled.

Chu Qing: "You said, is this the thing Xiaobao drew?"

Zhuo Yao pursed his lips: "It should...right! Boss, did you really make it?"

Chu Qing nodded: "Well, even so, but Xiaobao's letter said it would explode when it fell and smoked. I couldn't think of how to do it, so I could only light the open fire."

Zhuo Yao was very excited: "That's not bad, boss! This thing... makes this thing bigger, put it in a bamboo tube, add some chili noodles, lime powder or aconite, arsenic... It's okay to attack the city!"

Chu Qing looked sideways.

Oh my God! What's this kid's brain? "Martial Arts General Yao" was not created by him, right? He thought of all poison and smoke balls!

We must not tell the soldiers these things, they are so terrible, they all think of siegeing cities and territories!

Chu Qing decided not to take out the small explosive bottle and not let Zhuo Yao see it. It was too dangerous.

She sent Zhuo Yao out to find the fireworks workshop to see if there were any firecrackers that could be heard just after falling.

At this time, there was no place to sell firecrackers. Even if there were grocery stores, there were probably not many varieties. I could only go to the firecracker workshop outside the city to inquire.

Since I couldn't tell Zhuo Yao about this, I naturally didn't tell the boys at home. They were all dangerous people, so Chu Qing went to find Hou Ze.

Human thinking is so strange.

Because they knew that these soldiers had really been on the battlefield, they thought that the risk factors in their bones were very active.

I don’t know that the ship gang also killed people and robbed people (it may be because they are following Xiaobao now, so they subconsciously think that they are all docile?), so I think that Hou Ze is still relatively kind.

After finding Hou Ze, he thought about it again. His brother had to help with the aftermath of this matter, so he should not avoid him, so he asked him to find Wei Chengyi.

Then he also left the city with the bottle of explosives and smoke bombs.

When Hou Ze went to find Wei Chengyi, Wei Chengyi had just had a meal when he heard his subordinates say someone was looking for him. But when he saw that it was Hou Ze, he was pulled away without saying a word, which made the second monk confused.

There is a small basin to the east of Doutien Mine, and the center is a small lake. Because no one comes here because it is separated by the mine.

The three of them came here quickly, and Wei Chengyi didn't know what Chu Qing wanted to do.

Wei Chengyi: "If you don't allow lunch, what are you doing here?"

Chu Qing: "I made a small thing and wanted to see if it's easy to use."

When Hou Ze saw Chu Qing stuffing a bunch of small bottles into the bag, he couldn't help but joke with Chu Qing: "I see you carry a big bag of Xianglu, are you going to give it to my brother? You are so polite, I should ask my brother to give it to you!"

The children of the world should not be too thin. Chu Qing said: "Wei Chengyi, tell your brother what is the 'designated widow'."
