"Don't trust me so much?" Lin Zifan shook his head and smiled: "No need, these are enough!"

"Go into the kitchen, live, don't have too much fire, just a small fire!"

"My lord, I'll go!" Zhou Xiaoyan, who was like a little loli, hurriedly rushed into the kitchen, and Lin Zifan looked back at the civil and military officials and the empress.

"Then came the time to make gunpowder, but the mansion was not large, and the kitchen was even more crowded, and there was no room for so many people. A maximum of three people can go in and watch the ......"

"I'm gone!"

The empress said that she was going, which made the corners of Lin Zifan's mouth twitch slightly, and said in her heart: You really rest assured of me, and you are not afraid that I will make a mistake and blow up our husband and wife to the sky together?

But then again, with the strength of the empress, this amount of gunpowder doesn't seem to be able to threaten her at all.

"General Ben is going too!" General Huo Da's eyes widened, and he instantly forced back many generals and grabbed a qualification to watch the production of gunpowder on the spot.

Among the generals, those who dare to compete for positions with General Huo have not yet been born!

"Let's go too...... the old minister" The national teacher smiled and grinned at the civil officials, making everyone unhappy, but they were helpless.

Originally, Prime Minister Cao Cheng should have been the head of civil officials or something, but the national teacher was a high and powerful position, which made Prime Minister Cao Cheng's status a little sad......

It's just that the strength of the national teacher is still very strong, even if they use force, they can't beat them.

In the kitchen, the fire has been lit, Zhou Xiaoyan squatted by the stove, blinking a pair of big eyes while controlling the fire, looking carefully.

There was a pot on the stove, not very big, but enough to use.

"It's actually not difficult to make black powder!" Lin Zifan opened his mouth, and at the same time poured saltpeter powder into the pot and slowly stirred it with a wooden stick.

"There were no outsiders present, so I said it straight!"

He opened his mouth, and indeed did not hide everyone's thoughts, after all, once the gunpowder is made, the amount of weight required in the future will be huge, if you hide the method of production, make gunpowder by yourself?

"Saltpeter, charcoal, and sulfur are all ground into powder, and then slightly fried to allow the water to evaporate......"

"Adult...... Zhou Xiaoyan raised her little hand weakly: "That...... Shall I avoid it?"

The people present, Lin Zifan didn't need to talk about it, let alone the empress. General Huo and the national teacher, that is also an absolute high power, there is no possibility of doing anything, but she, a little palace maid, will she be killed after hearing these news?

"No, I believe you, and it's the same if you want to come to Your Majesty. Lin Zifan said casually, and the empress also nodded in agreement by the way......

In their opinion, there is no suspicion in employing people, and Zhou Xiaoyan's identity background is also innocent, and she is also very sensible, definitely not a spy or anything, let alone leaking secrets.

And when Zhou Xiaoyan saw the performance of the two, she was instantly moved and almost cried......

This made Lin Zifan look confused, and thought that something was wrong with this girl.

Subsequently, Lin Zifan explained while frying three kinds of powders.

"The fire can't be too big, you must fry it slowly on low heat!

"Charcoal and sulfur powder, the fire must be small! Otherwise, the charcoal may ignite and the sulfur may melt ......"

"Saltpeter itself is susceptible to moisture, so in fact, the most important thing to fry is saltpeter powder!"

"After frying the three powders and removing the excess water, they are mixed in a ratio of X to X to X......"

(PS: This ratio, Huan Yan can't say, after all, these three materials are too common, if people with ulterior motives see it, they really run to make gunpowder, Huan Yan will make a big mistake!)

The three powders were packed in a large bucket according to a certain proportion, and Lin Zifan began to stir.

"Be careful, at this time, you must use wooden products! Wooden barrels and sticks, not metal barrels, let alone metal sticks!"

"Why?" the empress and others were puzzled.

"Because...... Dangerous. Lin Zifan shook his head and smiled.

Mixing gunpowder with metal barrels and rods? Isn't that like smoking at a gas station?

Metals collide and sparks are generated, what happens if the sparks come into contact with gunpowder?

What's more, the people of the Tang Dynasty are all powerful people, so it's really not too simple to let them mix gunpowder and make sparks or something......

For the sake of safety, Lin Zifan simply set the rules directly, and he must use wooden barrels and sticks to mix!

In fact, in the original production of gunpowder, many times the three ingredients were mixed and then fried.

But in Lin Zifan's opinion, Tai Nima is dangerous, and after mixing it, isn't it gunpowder?

A powerful person like the empress is fine, even if the gunpowder is ignited, she can't hurt her, but a rookie like herself in the Xuan Realm ......

What if the gunpowder doesn't work and you kill yourself?

Even if it's not sealed, it won't explode, it will only burn...... But that moment of burning is enough to kill people, right?

Therefore, Lin Zifan separated the three materials and fried them, although it was a little troublesome, but it was safe.

Well...... It's not that Lin Zifan is afraid of death, but ...... Ahem, ahem, small lives are important, small lives are the most important!

The empress and the others watched as Lin Zifan mixed the three materials, mixing the three colors of black, white and yellow, and gradually turned into black......

As for the danger or something, when they heard Lin Zifan say that it was dangerous, they all pouted, even Zhou Xiaoyan on the side.

Gunpowder, they've never seen it. But that's all...... It seems that even if it burns, they are not afraid.

After all, unsealed gunpowder doesn't seem to be very powerful, at least for them!

However, in order to take care of Lin Zifan's face, they were embarrassed to say it......

After a while, Lin Zifan stopped stirring, straightened up, and let out a long breath.

"And then?" General Huo looked at with relish......

Well...... It seems to be quite good to see men do things seriously? Don't have some enjoyment!

"What?" Lin Zifan was stunned.

"And then how do you turn it into gunpowder?" added the national teacher.

"What else?"

Lin Zifan said speechlessly: "This is already gunpowder, right?"

Most of them looked incredulous: "This is gunpowder? Who are you fooling?"

"How is it possible! If gunpowder is so simple, why is it that only Yan Guo has been able to invent it for so many years?"

Although the empress was also a little unconvinced, she never said anything. Because Lin Zifan said that the fireworks that night were made of gunpowder.

Yes, in the empress's opinion, Lin Zifan must be able to make gunpowder.

But at the moment this step ...... It seems a little too simple, and it makes her want to believe it, but she hesitates for a while.

Because this really makes them feel a little 'ruined'.

It's so easy to make gunpowder?
