I took out the things and started grinding them. The process was too fast. After using them for a long time, I finally ground several things from granular to powder.

Rubbed my fingers, very thin.

"It should be enough," Zhang Xiu murmured.

"Lord, what's enough!" Hu Cheer scratched his head, revealing a confused look.

"Go and take the small scale." Zhang Xiu had no time to pay attention and directly ordered.

However, Zhang Xiu looked at the small scale he brought, and felt helpless. At this time, the more delicate the things, the harder it was to work, such as needles, such as measuring this little thing.

After pondering for a moment, Zhang Xiu brought a stone to press the scale, then put saltpeter on it, recorded the position of the scale, and then used the difference to accurately measure the weight of the items over and over again.

After working hard for a while, several things have been done, and it’s almost time to mix them.

After pondering for a moment, Zhang Xiu began to mix the prepared proportions and strive for a perfect fusion.

However, the accuracy of this era is not as accurate as that of later generations, and there will definitely be slight deviations, but this deviation should not affect the birth of gunpowder.

In fact, Zhang Xiu also knows that sulfur charcoal is a ignition-enhancing thing, while saltpeter will produce a lot of oxygen to help ignition when heated.

As for explosions, it is mainly sealing.

If gunpowder is not sealed, it will not explode. But if it is sealed, leaving a lead to ignite saltpeter, it will produce a lot of oxygen and produce very high heat energy.

Under the heat energy and powerful expansion, gunpowder will naturally explode, thus producing power. This is also the main principle of firecrackers in later generations.

Thinking of the same time, Zhang Xiu had already mixed the things, a small pile of things that looked like charcoal ash, but they were a little different from charcoal.

"Lord, what can this thing do?" Hu Cheer asked in confusion after he was idle.

"You will know when you look at it." After Zhang Xiu said that, he took out a flower, then lighted the cigarette with a lighter, took a few puffs, and then moved the cigarette butt to the pile of gunpowder.

Hu Cheer looked carefully and even shrank behind Zhang Xiu, a little scared. After all, after hearing what his boss said, it seemed that this thing was very powerful.

At this time, the smoke lit up on the pile of gunpowder.

Zhang Xiu was nervous and nervous.

Do you know if this thing works, wouldn’t it be too embarrassing if it doesn’t work?

Sigh!

In just a moment, a small pile of gunpowder burned out.

It was too fast, very fast, probably burned out without a breath, but it was just a black mark on the stone slab, which was quite conspicuous.

Hu Cheer: "???"

That's it????

Hu Cheer was completely in a bad mood. He widened his eyes and glanced back and forth on Zhang Xiu and Xiao Hei piles, as if he said again, Boss, are you fooling me?

This thing is amazing?

I'm afraid this will make the opponent laugh to death!

"Lord, this is it!" Hu Cheer pursed his lips and asked with a trace of hope for Zhang Xiu.

"Haha, it actually succeeded in one go." Zhang Xiu didn't have time to take care of Hu Cheer and said with a laugh. He originally thought he had to debug it many times.

But I think so, this ratio is only the best ratio. This ratio has been adjusted throughout the dynasties, and all three are combustible substances, so the success rate is very high.

As for whether it can be detonated, this requires repeated debugging, and this process takes a while.

"Uh, that's true!" Hu Che'er pursed her lips, feeling helpless. Her boss seemed to be unreliable. What's the use of this thing?

After working hard for a long time, this is it...

"Go, go and get me a slender small pot to let you know what black technology is." Zhang Xiu was a little excited and eager to try.

"Oh!" Hu Cheer nodded.

After a while, Zhang Xiu began to press gunpowder into the small pottery jar. The tighter the pressure, the greater the power. The firecrackers he played with when he was a child were mainly because of the low content of gunpowder.

Moreover, the density of gunpowder is also low, so you can only hear a sound.

After a while, the clay pot was filled, and a firing wire was pulled out, and the bottle mouth was blocked with something.

Looking at his masterpiece, Zhang Xiu smiled.

This thing is probably very powerful, right? But you need to be careful when igniting it. After all, the burning speed has not been tested in all aspects, so Zhang Xiu had to say, "Hu'er, go get two big shields."

"Master, why are you using a shield?" Hu Cheer pursed his lips and said.

"Just get it." Zhang Xiu said again.

After a while, Hu Cheer had no choice but to get two big shields, but he felt that his boss was a little bit of a big deal. He just put a flower on this thing.

Is it necessary to bring a big shield?

Zhang Xiu took it. He originally wanted Hu Cheer to ignite it, but after thinking about it, he went there himself. After all, this was done by himself.

"Stay still, stay away from the good shield!" Zhang Xiu explained, then approached the pot, took out the lighter, and ignited the object that caused the fire.

The moment he ignited, Zhang Xiu began to raise his shield and retreat.

Before this, Zhang Xiu also took out the camera to record videos, and also served as the timing function.

Before and after, there were only a few breaths in total.

boom!
