Gao Ming remembers that when he was a child, every time the Chinese New Year was the time, the happiest thing was to set off a firecracker, and after a firecracker was lit, he threw it directly into the public toilet, and then listened to the screams and angry scolding coming from inside, he would always feel extremely satisfied.

"Ah, what a beautiful childhood!"

It's a pity that later, with the deepening of the city's construction, not to mention the artillery battle, even the fireworks are not allowed to be released, without these two things, Gao Ming feels that the New Year is not very tasteful.

But now it's okay, no one cares about him in Datang, looking at the black powder that has been configured on the table, Gao Ming suddenly laughed sadly.

"Hey...... Hey, hey, hey, hey, hey......"

Gao Ming didn't plan to use paper to make artillery battles, because it was too troublesome, and he had to wrap and stick, he didn't have that patience, in order to save trouble, he directly chose the bamboo that was more common in the East Palace.

These bamboos are some thin bamboos, most of them are only as thick as a thumb, and they are all hollow, and the skin is not too thick, which is very in line with Gao Ming's requirements.

Gao Ming casually cut down a few trees, cut them into small pieces of about three inches, and then stuffed the black powder that had been configured into it.

After stuffing about three-quarters of the way, Gao Ming stopped, then put in the lead, and then sealed the mouth with the yellow mud that had been prepared.

Looking at the good artillery battle, Gao Ming laughed again.

"This is a veritable firecracker!"

Gao Ming was not greedy, he stopped after making more than 50 firecrackers, took these finished firecrackers to the yard to dry, and then he went back to the room to continue to configure black powder.

The servants and swords moved quickly, and every other time of incense, they would send the saltpeter powder, sulfur powder, and charcoal powder that had been ground to Gao Ming's house.

Gao Ming couldn't be busy alone, so he simply called Su Wan'er, Meng Xin, and Zhou Hong to help, and the three of them weighed and mixed the materials together, and wrapped the black powder that had been made in paper.

When people are busy, time always flies very quickly, seeing that the sky is getting darker, but the black powder is not fully configured, Su Wan'er also specially lit a candle and came in, as if she was preparing to "fight at night with candles".

Looking at the candle in Su Wan'er's hand, Gao Ming was suddenly so frightened that cold sweat came out.

"Wan'er, you stand at the door, don't come in!"

"Uh......"

Hearing Gao Ming's shout, Su Wan'er was stunned for a moment, and when she was stunned, she saw Gao Ming rushing over in two steps and one step, and then blew out the candle in her hand in one go.

After blowing out the candle, Gao Ming breathed a sigh of relief.

"Whew...... Wan'er, the name of this thing we are getting now is called black powder, this thing can be ignited at a point, don't say that it is on fire, as long as it rubs a little spark, you can catch it! ”

"Really?"

Seeing Su Wan'er's eyes widen and her face surprised, Gao Ming immediately nodded.

"Of course! Now there are about 100 catties of black powder that have been configured in our house, and if it catches up, it is estimated that it will burn my room, okay, maybe you don't believe it, then I'll show you! ”

After saying that, Gao Ming simply turned around and took a paper bag containing black powder, put it in the open space at the door, and then found a candle to light it.

These black powders were all wrapped in three layers of paper, and Gao Ming only lit the first layer of paper outside and hurriedly retreated.

As soon as he retreated, the fire had already burned through the two layers of paper inside, and then ignited the black powder wrapped in the innermost, making a "hissing" sound.

"Hoo ......"

Suddenly, I saw a bright flame rising into the sky, soaring high!

Seeing this scene, not only Su Wan'er and Meng Xin, but even the palace maids who were watching next to them all gasped together.

"Hiss......"

At this time, Su Wan'er finally understood what Gao Ming meant by "just a little bit".

Su Wan'er saw the paper bag that Gao Ming took just now, and there was only about a pound of black powder in that paper bag, and it was such a little black powder that could release such a high flame, which Su Wan'er did not expect.

This flame came and went quickly, and in less than ten breaths, the fire was slowly extinguished, and after the black powder was extinguished, a pungent smell suddenly spread in the field.

Gao Ming tugged on one sleeve to cover his mouth and nose, then turned his head to look at Su Wan'er, and found that she was still in shock, Gao Ming couldn't help laughing.

"Haha, Wan'er, do you see? Isn't this thing dangerous? ”

Hearing Gao Ming's words, Su Wan'er immediately nodded.

"Hmmm! It is indeed very dangerous, such a little black powder can be so powerful, if you set all those in the house on fire, I am afraid that the house will really burn down, and the concubine body will almost make a big mistake, I am willing to punish Lang Jun! ”

After speaking, she knelt down towards Gao Ming, Gao Ming's eyes were quick, he hugged her, and then smiled at her with a doting face.

"Fool, how could I blame you? Hurry up! ”

"Well, Wan'er thanked Lang Jun!"

Su Wan'er thanked Gao Ming, and then stood up, and at this time, Meng Xin, who was standing next to Gao Ming, also smiled.

"Hehe, Lang Jun, although this black powder is indeed dangerous, it is also very beautiful, and the appearance just now is like a spark!"

Sparkle?

Hearing Meng Xin's words, Gao Ming's expression suddenly moved, and he immediately turned around and went back to the house to take out a packet of black powder, and opened it and put it on the ground.

Then, Gao Ming took out a copper coin from his arms, then pulled out the barrier knife on his waist and began to scratch on the copper coin.

"Huh...... Boom ......"

Looking at Gao Ming's movements, Su Wan'er and the three of them suddenly showed a look of puzzlement.

"Lang Jun, what are you doing?"

Gao Ming didn't answer them directly, but gave them a mysterious smile.

"I'm not going to tell you yet, you'll find out later!"

Seeing that Gao Ming didn't say anything, Su Wan'er and the others didn't ask much, just quietly watched him scrape the copper coin with a knife.

After about a cup of tea, Gao Ming stopped, and then smiled at Su Wan'er and the others again.

"Alright, I'll show you something strange!"

After speaking, Gao Ming came to the courtyard with black powder, and then lit it.

"Hiss ......"

As before, when the fire came into contact with the black powder, the "hissing" sound immediately sounded, and in the blink of an eye, the black powder in the paper bag was all "whirred", and the firelight lit up the entire courtyard.

However, unlike just now, as the gunpowder heated, soon, the firelight turned green, and everyone present widened their eyes when they saw this scene.

"How is this possible?"

Looking at their stunned appearances, Gao Ming suddenly grinned and showed a smug smile.

"The color of copper when it burns is really green, but fortunately I haven't forgotten junior high school chemistry!"
