I am Wu Dalang, starting with Pan Jinlian

The third method is to dry the gunpowder with fire.

However, as soon as this idea came up, Wu Fei resolutely denied it!

Wu Fei didn't even dare to imagine, what was in his mind?How could there be such an idea of ​​praising martial arts?

Just kidding, this is gunpowder!
Once the gunpowder explodes, it can hurt muscles and bones in the slightest, and destroy houses and homes in severe cases. Even the shock wave may kill people.

Gunpowder is a thing that needs to consider the risk of collision when handling it. It will explode when the temperature is slightly higher, and it is something that others cannot hide!

Now you tell me, dry it with fire?

How great is this feeling!

Wu Fei felt that this heart must be as big as a house!
After driving this thought out of his mind, Wu Fei didn't bother to think about it anymore.

In the end, he chose the second method, spreading the pile of things into several empty pots and waiting for them to dry naturally.

After doing all this, Wu Fei clapped his hands in satisfaction and stood up.

"Master, it's getting dark, how about I light a lamp?" Wu Fu asked softly.

Wu Fei glanced at him in surprise and shook his head.

"This thing is called gunpowder, not to mention flames, even a single spark can ignite!"

Wu Fei pointed to the gunpowder spread in the wooden basin, and continued: "When you light the fire, you should stay away from this thing. If there is so much gunpowder, if it explodes, the room may be blown down. If it is serious, it will definitely collapse." The neighboring house may also collapse!"

Wu Fu was so frightened that Wu opened his mouth wide. He didn't expect that these things would be so powerful.

"Come on, close the doors and windows, and don't let anyone in!"

After speaking, Wu Fei walked out of the room first.

He came to the next room and told Wu Ren and Wu Yi not to grind sulfur powder, but to pack up their things and eat.

Although he was anxious, Wu Fei wanted them to continue working, but he thought it would be dangerous to prepare gunpowder under the light of a tung oil lamp, so he decided not to do it at night.

After dinner, Wu Fei sat in the study and sorted out his thoughts before going to bed.

This night, he continued to indulge himself, and the system tasks made him feel stressed.

Early in the morning, when the sky was just getting bright, Wu Fei got up.

I really miss you!
Wu Fei simply washed his face, then ran towards yesterday's house.

Opening the door, Wu Fei picked up a wooden basin and put it on the table.

After one night, the gunpowder in the pot appeared granular.

This appearance is exactly the same as the gunpowder in memory.

Wu Fei nodded in satisfaction.

This is the taste!Master Kang Braised Beef Noodles!

Wu Fei was taken aback for a moment, oops, I read the wrong line, photographer, cut this part out!

Closer to home, with the finished product, the next step is to test the effect.

You know, the system only gave three days to complete the task, and now it's the second day!

"Hahaha, I'm such a genius! Let the punishment for failing the system mission go to hell! I, Wu Fei's, will always be the original one! Wahahaha!"

The happy Wu Fei felt that this must be no problem.

He dug a spoonful of gunpowder with a wooden spoon, put it on a piece of rice paper, and wrapped it up.

This rice paper is not ordinary rice paper, it is left over from Wu Fei's handwriting practice.

The paper is densely filled with words, as if tens of thousands of ants are lying on it. Most people will definitely feel frightened when they read it!
But Wu Fei is not an ordinary person, he is in the second class, from elementary school to high school, even university, he has never been in the first class.

Picking up the ball of gunpowder, Wu Fei walked out of the room. He wanted to find another place to test the power of the gunpowder in his hand.

Regarding the danger of these dangerous goods, Wu Fei has enough safety awareness, so he didn't directly conduct experiments in a room covered with gunpowder, that would be too dangerous.

After wandering around the yard, Wu Fei chose a place!
It was a corner, far away from the room, so even if it exploded, it would not have much impact on Wufu's house.

Another advantage is that it is sheltered from the wind.

Satisfied, Wu Fei squatted in the corner, took out the lighter and lit it, and lit the rice paper.

When he lit the rice paper, his hands trembled a little, because he was a little tense.

Fortunately, the rice paper was quickly lit.

Wu Fei quickly stood up and took a few steps back.

At this time, the gunpowder in the paper bag was ignited, and only a puff of black smoke came out, and then there was no follow-up.

Wu Fei was completely dumbfounded!
He thinks this is not true, it must not be true!
This scene was beyond his imagination!
There was no deflagration, flame, or even explosion as expected, only a small puff of black smoke.

Wu Fei felt that this should be due to too little medicine, and he needed to increase the dose and try again.

So, he went back to the room, dug ten wooden spoons at once, put a large piece of waste rice paper in it, and wrapped it up.

After that, he took this big bag of things and went to the test site he had just selected, the corner of the wall.

The truth is so shocking!

Just like last time, after igniting the big pack of gunpowder, the black smoke was only a little bigger, and there was no other obvious difference.

Wu Fei was completely speechless!
This is really ideal and full, but the reality is too skinny!

"What's the problem?" Wu Fei fell into deep thought.

The formula must be fine. Gunpowder is made of three materials: saltpeter, sulfur and charcoal.

The problem now is that the power of the gunpowder is too small. This should be a problem with the ratio of ingredients!
However, he clearly remembered that the ratio should be one sulfur, two nitrates, and three charcoals, which is fine!
So what went wrong?Is the purity of the raw materials not enough, or the formula is wrong?

Wu Fei felt a headache. If it was a matter of purity, he really didn't have any good solutions for the time being.

But if the formula is wrong, it will be troublesome.

Experimenting with a recipe is no easy task!
Fortunately, there are only three raw materials, and now I have tried the formula with charcoal as the majority, so next, I can try the gunpowder formula with a higher proportion of sulfur or saltpeter.

In order to save time, Wu Fei decided to configure two different types of gunpowder at the same time, one is sulfur accounting for [-]%, and the other two raw materials each accounting for [-]%.

The other is that saltpeter accounts for [-]% and charcoal and sulfur account for [-]%.

Just as he was about to enter the house and start to prepare new gunpowder, Wu An came over and said that Yang Yanzhao had come again.

Wu Fei patted his forehead and asked Wu An to bring him over.

"Brother Wu, is the gunpowder ready?" Yang Yanzhao asked Wu Fei when he saw Wu Fei from a distance.

Wu Fei rolled his eyes, a little speechless, but it would be impolite not to answer.

"The configuration is better, but the effect is not very good!" Wu Fei paused and continued, "You can ask someone to get some raw materials back!"

"How much do you want this time?" Yang Yanzhao asked.

"Another ten catties!"

"Ok, no problem."

After finishing speaking, Yang Yanzhao turned his head and told a guard beside him to get some raw materials back.
