My wife is a sword god

"What was that just now?" Qin Feng looked in the direction of the palace and murmured.

Even though the golden dragon had disappeared, he seemed to still hear the terrifying dragon roaring in his ears, and could still see the posture of circling in the sky with its fangs and claws.

And he had a vague illusion that when the golden dragon turned its head, the reflection in its huge dragon eyes was his figure.

The elder seemed to have guessed something and looked at Qin Feng meaningfully.

Although the others were also very shocked by the golden dragon, they were more interested in gunpowder than the golden dragon!

"Old man, what you made just now was the gunpowder that Master Qin mentioned?"

"I don't understand why those materials can exert such great power when they are fused together. Is this also the mystery of physics?"

At this moment, everyone focused their attention on one person, their eyes were extremely hot!

Qin Feng coughed dryly and replied: "This is still somewhat different from physics, but even if I want to explain it to you, it is difficult to understand the reason with your current level of knowledge.

I can only tell you that this is called chemistry, you can also call it alchemy."

Having said that, the fact is that he himself cannot explain the principle clearly.

"Chemistry, alchemy?" Everyone's eyes were shining, and they seemed to have seen a brand new door again!

"I am afraid that only Master Qin can do such a magical thing!"

"Master Qin, can you also teach us this alchemy?"

"The principle of gunpowder generation, if you can tell me a little bit, we will be very grateful!"

Qin Feng showed a thoughtful look on his face. It was not easy to make gunpowder, and it must be mass-produced.

After all, gunpowder that ordinary people can also use can help the human race better fight against demons.

But everything has two sides. Gunpowder does not require high requirements for users, which is both a good thing and a bad thing.

If used by people with ulterior motives, such as those rebellious mountain bandits, gunpowder will bring disaster to the human race.

Just when Qin Feng was thinking about whether to teach the method of making gunpowder, the elder said: "Today's incident, everyone in the Divine Workshop should treat it as if it did not happen.

Gunpowder is of great importance. If people with bad intentions know about it, it may cause disaster."

The elder has lived for a long time, so he can naturally foresee what Qin Feng is worried about.

When the people in the Divine Workshop heard this, they instantly understood the interests involved.

Gunpowder with such amazing power, but without too many requirements for the user, if it is controlled by people with ulterior motives, it will no longer be a blessing for the human race, but the source of disaster!

"We understand." Everyone said in unison, and never mentioned the matter of gunpowder.

"Boy, come with me." Yuan Zhai said so, then turned around and walked towards the upper floor of the attic with his hands behind his back.

Qin Feng was stunned for a moment, and then followed.

Arriving at the fourth floor of the attic, the old man asked: "What exactly is the alchemy you are talking about?

Why do different types of materials undergo such strange changes when they are fused together? This is completely different from its original properties."

In the inherent thinking of the old man Yuan Zhai, iron is iron and gold is gold. No matter how you hammer it or forge it into any shape, its essence cannot be changed.

However, the birth of this gunpowder has far exceeded his cognition.

He wants to explore and want to know the mystery.

Qin Feng didn't want to answer at first, because he himself only knew a little, but seeing the old man's inquiring eyes, he still thought about it and roughly explained it.

"In fact, most substances in the world are not what we see on the surface. They have a deeper and more subtle essence. In the field of alchemy, they are called elements.

The combination of saltpeter, sulfur, charcoal and other materials can become powerful gunpowder because of the reaction produced by the combination of the elements they contain.

Can the old man understand me when I say this?"

The old man raised his head and said nothing.

But Qin Feng could see from the other party's confused eyes that the elder didn't understand the principle at all.

There was no way. The concept of elements was too advanced for people of this era. He couldn't recite a section of the periodic table in front of the old man, right?

"Forget it." The elder sighed: "Let's talk about the gunpowder first. This thing is powerful and has no requirements for the user.

This undoubtedly gives the human race an extra guarantee against demons and ghosts.

But if it is not restricted and gunpowder is rampant among the people, it will inevitably have extremely serious consequences."

Qin Feng nodded in approval after hearing this: "What the elder said is also what I have been worried about, but I have a solution."

"What solution?" Yuan Zhai asked.

"Reach a cooperation with the imperial court, the army, and the Demon Slayer Bureau, provide them with gunpowder, let them control the raw materials of gunpowder, saltpeter and sulfur, and fundamentally solve the problem of gunpowder being abused."

This answer was somewhat unexpected by the old man: "This method is indeed feasible, but it may be difficult to implement.

You should know the principle that a man is innocent but guilty of possessing a treasure.

If they know that the source of gunpowder is here, then you will not have the final say."

Qin Feng smiled and replied: "I am naturally very clear about this principle, so if I want to implement it, I still need the help of the elders.

I don't have any connections in the court, I hope you can help me with this."

"You mean that you can handle the army and the Demon Slayer Division yourself?"

Qin Feng raised his eyebrows and replied: "To be honest, elder, my wife's surname is Liu, and her name is Jianli."

"I see." Yuan Zhai nodded.

The Liu family, which is in charge of the Shenhou Army, has a say in the army.

"As for the Demon Slayer Division," Qin Feng glanced at the Qingyu Demon Slayer Order on his waist.

The Qingyu Demon Slayer is a symbol of status in other places, but it is not enough in Fengtian City. The only thing he can rely on may be his relationship with Master Dao Kuang and Senior Gun Immortal.

And when he left Jinyang City, Master Zhou Kai also gave him a letter of recommendation from the Demon Slayer Division to facilitate his entry into the Demon Slayer Division in Fengtian City.

It's just that since he came to Fengtian City, he has been dealing with other things, so he hasn't had time to go there yet.

"Next, I must find time to go to the Demon Slayer Division to get to know the door. "Qin Feng thought so, this is not only to establish connections, but also to promote gunpowder.

Then, he explained to the old man how to use gunpowder correctly-

"Elder, although gunpowder is powerful, it cannot be ignited directly, otherwise it is too dangerous.

I have a design here that can store gunpowder and then ignite it with a fuse.

This not only allows the user to have enough time to escape, but also controls the detonation time, and can determine the detonation intensity by changing the amount of gunpowder.

Next, I need you to help me make some of this stuff, which will also be convenient for showing to the court, the army and the Demon Slayer Department in the near future. "

The old man couldn't help but be attracted by this wonderful idea: "It's interesting, I understand. "
