Nangong Rui followed the girl with a serious face, looked around, and walked into the cloth shed, what kind of fame can be made in such a humble place?

There was a wooden table in the middle, a pile of white stones piled up in the corner, and a bag next to it, probably sulfur charcoal or something, miscellaneous things piled together, messy but not messy.

"Xi Yao, what are you going to do? Are these broken stones or are there these messes? What is it used for? Isn't it that the queen really wants to dig coal? ”

Nangong Rui sat beside Yun Xiyao calmly and asked jokingly.

"Why do you have so many questions? Willing to stay here and honestly find a place to sit, away from me, how far away from me, this girl has to do big things now, time is pressing, can't be sloppy, don't make trouble for me, otherwise I will never be spared. ”

Yun Xiyao was like an angry little tiger, grinning at the man, she could only straighten the corner, she was really inflated, where are there so many why?

Wasting your time in vain and not knowing how important this is? Isn't it good to look at it honestly? "Whatever happens, don't bother me, do you hear? Otherwise, walk out right now. ”

Nangong Rui's expression was solemn, and he became more and more puzzled, looking at the girl's cautious appearance, he raised his hands, "Okay, good, the queen mother Chitose Chitose Chitose!" I promise not to bother, okay? ”

The man smiled helplessly, pulled a chair, and sat on it casually, eager to swear to the sky.

The little queen is angry, as soon as possible, I don't know what to do? Isn't it boring to yell and follow me over, the first time I dislike myself and get in the way, and I pity myself to see what I did wrong?

Yun Xi Yao pointed at him with a smile on his face, his face became serious, he sat on the simple experimental table, picked up a small stone, and slid it over the fire.

The spark artifact of infatuation, and after a while, a flash of green smoke flashed.

Nangong Rui's eyes were deep on this white stone, it was so strange to get up at night, what the hell is this girl liar doing?

The corners of Yun Xiyao's mouth rose, and she was busy from morning to night until now, saltpeter is extremely rare in the whole Yunzhou, and some doctors with superb medical skills are used to treat diseases, but this is not something that ordinary people can afford, only the rich and noble princes and nobles can use it, which shows how scarce it is.

It was only after running all over Xuzhou that I found a few small pitiful saltpeter piles to make black powder and fill the Flying Dragon Hall Divine Soldiers.

This time the saltpeter mine was discovered by chance, it was like a pie in the sky, cough cough, Yan Yuming should be renamed Timely Rain.

With these things, the Flying Dragon Hall will have a qualitative leap, and the strength of the Yunxi Dynasty will undergo a transformation and go to a higher level.

What Yun Xiyao has to do now is to turn these steps into reality, put down the things with a smile, put them in the tray, and crush them gently.

"I didn't expect that the saltpeter content is quite high, and if you want to exert greater power, you still need to purify."

And this is also his old job, in addition to the identity of an agent, he is also a master of playing with various weapons, up to intercontinental missiles down to ordinary ammunition, he is very obsessed, and he stays at home whenever he has time, engages in all kinds of experiments, and sometimes does not go out for a month.

Especially the development of new weapons, this is a recipe for forgetting to sleep and eating, and I have to say that because of this, I bombed myself into the sky and came here in a daze.

Nangong Rui fortunately didn't know about it, otherwise he would not let him touch these strange things if he knew these things, and you said that he honestly squatted aside and watched her play with fire.

Yun Xiyao's but not unreasonable, put all the messy thoughts behind her, and seriously continued the experiment in her hands.

It is said that people who do things seriously are full of charm, which is not false at all, regardless of whether it is a man or a woman.

In the past, Nangong Nangong Rui carefully reviewed and dealt with the government, Yun Xiyao, obsessed with the charm of men, that face had a hint of charm, and every gesture had a fatal charm, which made people reluctant to leave their eyes.

Nangong Rui sat quietly beside the girl, looking at him, sometimes serious, sometimes excited, smirking, his eyes were unpredictable, and the corners of his mouth were also raised with an imperceptible arc.

Write that seeing the little guy so solemn and doing one thing sincerely, it is really a little goblin who can't cry and laugh.

A strand of broken hair gently swept in front of Yun Xiyao's forehead, hanging down to her ears, the fireworks flickered, the broken hair danced lightly, and the man couldn't help but scratch a touch of strangeness on his heart.

The wild thoughts ran away, Nangong Rui was cold and arrogant on the surface, his thoughts were flying, staring at the girl's thoughts.

Nangong Rui knew that many of the core things of the Flying Dragon Hall were written by the little queen of his family, but he had never seen it with his own eyes, although he didn't know what he was doing now, he also had a faint feeling in his heart that it must be a rare good thing.

Time flowed quietly, passing silently bit by bit, and half an hour later, the long table in front of Yun Xiyao was on the top, and piles of black powder were placed in turn.

The sparks sparked, one after another, Nangong Rui's eyes tightened, and he stood up suddenly, like a gust of wind, and even came to the girl's side, without saying much.

Staring at the pile of black powder, the thin lips were lightly hooked, it was incredible, this series of sparks was actually burned out of black powder the size of a fingernail, could it be that this is the treasure at the bottom of the box that Feilongtang does not say?

Looking at the dignified appearance of the little guy, he must be inseparable from ten, and he was really lucky to see this unforgettable scene.

Yun Xiyao suddenly came back to her senses, realizing that there was one more person beside her who couldn't cry or laugh, she looked back lightly and blinked lightly, "Rui, give me a little quickly, otherwise it won't hurt you for a while, I'll be fine for a while, don't worry." ”

Not good!

I accidentally slipped my mouth.

What can be done? The experimental conditions in this world are very simple, and the safety factor is not high, so he can only rely on himself to experiment little by little, and he doesn't understand this.

Let the man stay away from him is afraid of what happens, he is used to it, he reacts quickly, and he will be fine, if the man is worried that he will abide by his family education, he will be hurt.

Nangong Rui's eyes suddenly turned cold, staring at Yun Xiyao, "This is Black Fire?" ”

This thing first came out of the Flying Dragon Hall, and then the entire Yunzhou was very famous.

When I was still in business, I had already heard that this thing was quite mysterious, the amount was very small, and the Feilongtang was strictly controlled, and it was not exported for internal use.

It doesn't matter if you are an emperor or a martial arts master, it is simply priceless, and you can't buy it at all.

I don't know the true face of the black fire, but I am not in this mountain.

At the time of the Battle of Cloud Cliff, you must have seen the power of black fire first, and I still remember it vividly, at that time, my little queen, with chiseled words, bombed the Great Snow Mountain, and buried the divine soldiers of the 10,000 soldiers of Shuiyue, which was filled with black fire!

Unexpectedly, it was the inconspicuous pile of black powder in front of me......
