My wife is a sword god

As the man entered the attic, heat hit his face.

The weapon refining room that was blown up by Qin Feng has been completely renovated and has obviously been transformed.

The heavy door looked very strong at first glance, and there was a small hole at the height of a person.

At this moment, Gong Liang was throwing black ball-like explosives into the weapon-refining room through the small door on the side of the weapon-refining room.

Huo Yuan, on the other hand, wore a special object that looked like glasses and carefully observed the movements in the weapon refining room through the small hole.

boom!

With a dull sound, the entire attic trembled.

Huo Yuan said excitedly: "The 342nd explosive test exploded successfully, hurry up, hurry up, next one, next one!"

Qin Feng, who was not far away, looked shocked when he heard this. No wonder he had successfully refined explosives a few days ago, but the finished product had not been brought to him for so many days.

Have you been doing tests for a long time?

Is it necessary to waste so much explosives for testing three hundred and forty-two? !

"Okay, no problem." Gong Liang, who was standing by the gate, looked excited, and then took out a brand new explosive from the space treasure.

Seeing that Gong Liang was about to throw the explosive into the refining room, Qin Feng hurriedly stopped him and said, "Wait a minute!"

When the two heard this, they looked for fame with unhappy expressions. They wanted to see who was so bold and delayed their happy moment.

"Master Qin?" After seeing the speaker clearly, the expressions of the two people instantly changed from anger to joy.

"What are you doing?" Qin Feng asked confused.

Huo Yuan and Gong Liang looked at each other: "Let's test the gunpowder."

"Do you need to test hundreds of them for testing? Where did you get so many explosives?"

"Oh, these are all made by us in recent days. They have been tested and they can all be detonated successfully!" Huo Yuan and Gong Liang couldn't hide their pride in their voices.

At the same time, they also admire Master Qin very much. After all, this explosive can definitely be said to be an unprecedented great invention!

"Test all?" Qin Feng twitched the corner of his mouth, and a bad premonition suddenly emerged: "You shouldn't have tested all the explosives, right?"

Hearing this, Gong Liang shook his head and said, "Of course not."

Qin Feng just wanted to breathe a sigh of relief when he heard the other party speak again: "I still have more than ten explosives here that I haven't had time to test. Master Qin, you are here."

Qin Feng only felt that one head was as big as two: "You guys took all the explosives to test and detonate them. Then what should I show to the Demon Slayer Division and the army?"

Gong Liang retorted: "But if we don't test it in advance, how can we be sure whether the explosive is successfully made?"

Huo Yuan added at this moment: "Yes, if you make a defective product and show it to others, there will be no reaction.

That is not only a slap in the face of Shen Gongfang, but also a slap in the face of Master Qin. "

"Uh" Qin Feng was speechless. What he said made sense?

After thinking for a moment, he finally reacted and snatched the remaining ten explosives from Gong Liang's hands, and solemnly warned: "You can do tests in the future, but for every ten you make, you can only take one." Testing, this is called sampling testing.

This detection method can not only control the number of defective explosives, but also preserve good explosives as much as possible.

You two, do you understand what I mean? "

Huo Yuan and Gong Liang were a little embarrassed. In the past few days, they had fallen in love with the feeling of explosion.

If we really follow what Master Qin said, wouldn't the happiness we can enjoy in the future be much less?

Perhaps seeing what they were thinking, Qin Feng threatened: "If you don't do what I say, I will never come here to give lectures again."

The two men immediately said in unison: "I will obey Master Qin's order."

After parting ways with the two, Qin Feng came to the floor where Mr. Yuan Zhai was.

At a glance, several wooden boxes were densely packed with prepared explosives.

"Senior, these"

Yuan Zhai said: "Have the Demon Slayer Division and the Shenhou Army taken care of it?"

"Yes."

"Then it's time for me to go to the palace. Those two little bastards don't do things lightly, so I think there won't be much explosives left.

Take two boxes of the explosives here and bring them to the Demon Slayer Division and the Shenhou Army.

In recent years, the four regions have been in trouble. With the assistance of gunpowder, many unnecessary casualties can be avoided. "

This is exactly what Qin Feng expected to see: "Master Yuan, when do you plan to go to the palace?"

"Today at the earliest and tomorrow at the latest.

You made gunpowder and made a huge contribution to Daqian. Emperor Ming will definitely reward you.

But the common man is not guilty of carrying a jade, and there are some things that he has to guard against. Yuan Zhai warned.

"Junior understands."

The old man nodded and asked, "Why did you come here to look for me?"

"It's like this. The New Year is approaching, and the New Year's Eve Ceremony is coming soon. I was entrusted by my friends and wanted to ask the old man to help me make some gadgets for the celebration."

Yuan Zhai frowned: "At this time, there are always many people looking for me with these insignificant things.

Do you think I have time to care about this? "

Qin Feng immediately took out a book from his arms, with the three characters "Alchemy" written on it. He opened the title page and saw the periodic table of elements, but only the first twenty numbers were written on it for the time being.

"I had nothing to do in the evening. I summarized some knowledge. I don't know if the elder is interested."

Yuan Zhai put the book in his arms and asked instead, "What do you need me to do?"

"That thing is called fireworks, or firecrackers. It's not difficult to make. The main ingredients are gunpowder and some metals. I'll tell you the general method."

After everything was explained, Qin Feng took away two boxes of explosives and left the Shen Gongfang with Ningshuang.

He wanted to go directly to his father-in-law's house to show the power of explosives, but when he looked up at the sky, it was gradually getting dark.

Just at this time, Lan Ningshuang said, "Son-in-law, why don't you go back home earlier today?"

"Hmm? What's wrong? Is there something at home?" Qin Feng asked curiously.

"It's nothing big, but when I left the Qin Mansion today, the lady told me that there were some things she wanted to show you." Lan Ningshuang said softly.

"Jianli has something to show me?" Qin Feng raised his eyebrows, and then his imagination ran wild.

After a while, he shook his head again, shaking off the messy thoughts in his mind. After all, there were no uniforms and black silk in this era!

"What is it?" Qin Feng asked again.

Lan Ningshuang pretended to be mysterious and said, "The lady didn't say anything specific, but just asked the son-in-law to wait in the room when the time comes."

These words made Qin Feng a little distracted. After sleeping for several days, could it be that the lady wanted to eat meat?

But he didn't expect that the lady who didn't know the ways of the world would know to give expectations in advance. When did she become so playful?

"Ningshuang, have you bought a storybook recently?" Qin Feng said seriously.

"No, no." Lan Ningshuang blushed. How come the son-in-law even knew this.

"Heh." Qin Feng didn't expose it, but was glad that the prescription given by the Liu family's grandmother had not been thrown away.

Tonight, I'm afraid I won't be able to sleep well.
