My wife is a sword god

But Qin Feng was disappointed. Apart from the Transformation Box that the man took out at the beginning, the rest of the things were useless!

Let's talk about the gravity disk first. It can indeed change the gravity within a radius of ten feet, but the magnitude of the gravity change is too small. At most, it can make the feathers float into the sky!

But you have to know that the feathers will float up with just a gust of wind.

As for Huo Yuan's flying wings, Qin Feng was full of expectations when he first heard the name.

What man can refuse the romance of flying in the sky?

But the greater the expectation, the greater the disappointment when seeing the real thing.

Glancing at the ground, Qin Feng saw two gorgeous wings as big as an adult. His eyelids jumped: "The design does conform to the aerodynamics I mentioned earlier, but you made the wings so big that ordinary people can't wear them. How can they fly into the air?"

"Master Qin doesn't know. I designed this with reference to flying birds. Even the proportion of wings to the human body is based on birds as a reference."

Qin Feng's face froze: "Then do you know that the body structure of birds is different from that of humans, and their skeletons are much lighter.

Let's not talk about anything else. Can you wear this pair of wings yourself?"

Huo Yuan's face changed, and he replied calmly: "Although I can't wear it, there are always people who can wear it."

"For example?"

"A warrior in the fifth level of Shenwu Shenxing realm." Huo Yuan replied confidently.

Qin Feng took a breath of cold air. He felt that his IQ was insulted: "Martial artists of the fifth level can already fly as light as a swallow. What's the point of them installing a pair of wings on themselves?

Would you install another pair of wings on a bird?"

Huo Yuan seemed to think it made sense. After pondering for a moment, he said, "Master Qin, don't you think this pair of wings looks pretty good on you?"

Qin Feng wanted to swear, but his good upbringing made him take a deep breath and calm down.

He picked up the Transformation Box and said solemnly, "Here, I want to praise this student by name. He loves learning and thinking, and what he has made is very practical!

As for the others, I can only say that the idea is good, but there are too many areas that need to be improved. Wait for you to think about it yourself. After the improvement is completed, bring it to me for evaluation."

The man who was praised by name raised his head, puffed out his chest, clasped his fists and said, "Thank you, thank you."

The others all showed an expression as if they had eaten a fly, not to mention how uncomfortable they were.

And they secretly swore in their hearts that they must make something new and interesting that Qin Feng would praise next time!

After inserting the Transformation Box into the Xumi Ring without leaving any trace, Qin Feng continued his course.

Everyone was concentrating and taking notes seriously, and some people would ask some questions from time to time.

But no one noticed that there were three more figures at the entrance of the hall.

"So that's what happened. I benefited a lot, benefited a lot!" The man holding the small stool wrote on the blank paper. He had missed some classes, so he naturally couldn't miss any other details!

The man in the battle uniform looked at the handsome young man surrounded by everyone in the center, and asked in confusion: "Is this the Qin Master you mentioned? Who is he? How can he have such appeal in the Divine Workshop?"

In the Divine Workshop, because everyone is fighting hard in their hearts, basically no one is convinced by anyone.

Only Master Yuanzhai can make these people convinced.

But the scene in front of him was beyond the man's expectation. In addition to the elder, there was someone who could make the group of people in the God Workshop so respectful?

"Hehe, how can a crude warrior like you understand the greatness of Master Qin? His mind is full of everything. The knowledge in it, even if it is just a little bit of scraps, is enough for you to study for a lifetime."

The man in combat uniform frowned when he heard this. He was about to say something, but suddenly found that the woman in the long skirt was strange.

At this moment, the woman was staring at the center of the hall, her red lips slightly opened, with confusion, surprise, and even a hint of surprise in her eyes!

"Why is he here? Shouldn't he be in Jinyang City?" The woman murmured to herself.

"Princess, princess, what's wrong with you?" The man in combat uniform asked in a low voice.

"Ah?" The woman was a little flustered.

Qin Feng, who was surrounded by people, raised his head and looked at the entrance.

I saw a man holding a bench and writing there.

"Uh, why doesn't that guy sit down to listen, but stands with a stool?" Qin Feng didn't understand, shook his head and continued to explain the course.

In the courtyard of the Divine Workshop, the man in combat uniform asked puzzledly: "Princess, aren't you going to ask the people in the Divine Workshop to make some novel things for the New Year's Day? Why are you leaving?"

The woman's eyes were a little evasive: "I suddenly thought of something that needs to be dealt with, and they are still teaching. It would be impolite to interrupt them at this time.

I will come to the Divine Workshop again later."

As soon as the voice fell, she lifted her skirt and walked out of the gate of the Divine Workshop, heading to the right.

"Princess, our carriage is on the left."

The woman holding her long skirt was stunned when she heard the words, and then silently turned around.

"Okay, today's class ends here. If I have time next time, I will come to share the mysteries of physics with you.

Oh, by the way, during this period, you can also think more divergently like this student and make some achievements to verify what you have learned.

As the saying goes, "If you study without thinking, you will be lost, and if you think without studying, you will be in danger." Qin Feng put his hands behind his back, acting like a teacher.

The man who made the illusion box heard this and immediately responded, "Master Qin said it very well. If you study without thinking, you will be lost, and if you think without studying, you will be in danger. You must remember it in your heart!

I will not be complacent because I made a thing. In the days to come, I will carry forward Master Qin's knowledge of physics and strive to make more and more valuable things!"

The rest of the people in the God Workshop heard this and smacked their lips in disdain.

"Not bad." Only Qin Feng cast a look of approval, like a kind elder.

If everyone can make something useful like this person, then he will make a fortune.

"Then again, shouldn't I also tinker with something?

This era is so chaotic, but gunpowder seems to have not been invented yet.

If I can make gunpowder, even ordinary people will have the power to protect themselves and fight against demons, and it can also greatly reduce the losses of the army in the fight against demons.

Let me think about what the ingredients of gunpowder are -

It seems to contain saltpeter, sulfur and carbon-containing substances, with a ratio of about 2:1:1.

However, if you want to make gunpowder, the process is still too dangerous. I have to think carefully and plan it well. "

Qin Feng had already thought of making gunpowder in his mind.
