My wife is a sword god.

Chapter 388
boom!
Just when Ya'an was full of thoughts, accompanied by a roar, firecrackers soared into the sky.

Everyone in the busy God's Workshop in the courtyard was taken aback, and hurriedly searched for fame.

Then I saw, high in the sky of Shengongfang, under the light blue barrier, light green flames bloomed, like a huge blooming green flower.

The scene was really like a fairyland.

Everyone was immersed in this beautiful scene, but this grand scene came and went quickly, like a flash in the pan.

"How?" Qin Feng turned around and asked with a smile, but no one answered.

Everyone obviously hasn't recovered from the scene just now.

Huo Yuan and Gong Liang were the first to speak out, and they hurried to the front: "Master Qin, that thing just now was the fireworks you asked us to make earlier?"

"good."

"It's strange, after the completion of this object, we also tested it in the refining room, but we didn't see such a scene." Huo Yuan scratched his head and said.

Gongliang also said: "The explosive power of that thing is too small, we all treat it as a defective product, but we didn't expect it to have such an effect.

However, Master Qin, why is the color of the flame green? "

Qin Feng replied: "Do you still remember the tiny metal that you were asked to add in it?

Different metals will show different colors under high temperature. I call this phenomenon flame reaction, and the colors you see are also derived from this. "

"Flame reaction?" Huo Yuan's eyes showed excitement.

"I have benefited a lot, I have benefited a lot." Gong Liang took out a notebook from nowhere, and it was full of notes.

Qin Feng glanced at it briefly, and the contents recorded in it were all the things he had talked about in the opening class.

In my previous life, if I had been so serious in taking lectures and taking notes, I wouldn't have failed the [-] exam. Qin Feng showed a weird look.

He didn't continue to pay attention to these two people, but turned sideways to the young man in white who bowed his head and pondered: "How, this thing should be more than enough to present as a congratulatory gift?"

Ya'an came back to his senses: "Please order a few more and let me see."

Qin Feng immediately refused: "This item is a scarce commodity. If you order it now, what else will you give to Emperor Ming?"

It made sense for Ya'an to think about it carefully, so he planned to ask Wang Xu to put away the fireworks and firecrackers, thinking that later, as a princess, he could ask Shen Gongfang to withhold some gunpowder from other places to make more fireworks and firecrackers.

But at this moment, Liu Jianli, who was dressed in white, suddenly said, "I want to take another look."

Without further ado, Qin Feng immediately took out a few more firecrackers from the wooden box.

Ya'an opened his mouth, his expression a little dull.

This discriminatory treatment is too obvious.

Looking at the gorgeous fireworks, holding hands, the two with happy smiles on their faces.

Ya'an, who is alone, looks like a defeated dog.
After a stick of incense, Qin Feng said helplessly: "Isn't it just that you ordered a few more sticks? I need this look. At worst, I'll find a way to get Mr. Yuan to make you some more."

Ya'an ignored it, just glanced at the wooden box with only a dozen firecrackers left, and sneered: "After the advent of gunpowder, the demand for gunpowder by the imperial court, the army, and demon slayers has increased day by day.

Moreover, saltpeter mines are scarce, and with limited raw materials, even if some can be extracted to make fireworks, it is extremely limited. "

Qin Feng's face froze. This statement was true, after all, Mr. Yuan also said the same thing just now.

He thought for a moment, then suddenly thought about it, and then took out something from his bosom, which was the illusion box that he got from the Shengongfang people earlier.

"What is this?" Ya'an asked puzzled.

"This object is called the illusion box, and its specific functions are"

After some explanations, Qin Feng said: "Think of this thing as I borrowed from you. On the night of the celebration, you can use the illusion box to reflect the scene presented by the fireworks.

In this way, the problem of insufficient number of fireworks and firecrackers can be solved. "

"That's the only way to go."

After Qin Feng and others left from Shengongfang, Ya'an left and returned.

Huo Yuan in the courtyard asked curiously, "Why are you back?"

"Some things were left in the attic." Ya'an said lightly.

"Ordinary people can't enter and leave the old man's attic at will. Tell me what you left behind, and I'll fetch it for you." Huo Yuan raised his eyebrows.

Apart from his own family, the only one who can enter the attic at will is Master Qin.

It's fine if the other party enters with Master Qin, but it's obviously not qualified to come alone.

But just when Huo Yuan was thinking this way, the old man's voice came from the attic: "Let him in."

Huo Yuan was a little surprised, but the old man had already spoken, so he naturally didn't ask any more questions, and gave way to the attic.

Ya'an came to the floor where Mr. Yuan was, and said directly: "There are still five days before the Hexin Grand Ceremony, how many fireworks can you make?"

Yuan Zhai looked at the blueprint in his hand and asked, "Are you asking this as the head of Jubaozhai, or as a princess?"

That's right, the old man knew Ya'an's true identity. After all, the treasure that Ya'an possessed that could conceal his aura and change his appearance and figure was made by the old man!
Ya'an sighed: "Mr. Yuan, why bother to ask knowingly, if I am the head of Jubaozhai, I'm afraid I won't even be able to enter your attic?"

Yuan Zhai put down the blueprint and turned his head to look: "If you can get Emperor Ming's consent to withhold part of the imperial court's gunpowder, Shengongfang can make nearly a hundred more fireworks for the princess."

After Ya'an heard the words, he agreed after a little thought.

Compared with her ineffective elder brother, her princess is more loved by her father. It is not difficult for her to get some gunpowder.

After the matter was finalized, Ya'an was about to leave when he suddenly thought of something and asked, "Why are you so respectful to that guy? Is it because the immortal is drunk with gunpowder?
When I came last time, I happened to see him giving you a lecture. What is he teaching you? "

Yuan Zhai didn't answer, but casually threw out the previously recorded physics book.

Ya'an took the book with a curious look on his face, and then flipped through it.

Then she was immersed in the fantastic knowledge in the book, unable to extricate herself.

"You are studying in the hands of the Tianjian Guoshi of Haowen Academy, you should know how unconstrained the knowledge is.

This is like a treasure to us craftsmen. "

Ya'an was silent, and after a long time, he asked again: "The content in this book is all what he said?"

"According to that kid, there is a teacher behind him, but we don't know if it's true or not." Yuan Zhai replied truthfully.

"Aren't you curious? The person who can write this book is definitely not an ordinary person." Ya'an's tone was a little excited.

"So what, it doesn't matter where the knowledge comes from, as long as we can learn it."

Ya'an was at a loss for words, so there was no problem with what she said, it was just that she wanted to find out where Qin Feng was from.

After all, all kinds of whimsical ideas in that guy's mind always make her full of curiosity.

"I can take this book home to read."

Before she finished speaking, the physics book had disappeared in her hands.

Yuan Zhai said, "I've kept the fireworks in mind, so I won't give them away."

Ya'an: "."
