Facing everyone's doubts, Qin Yunfei smiled dumbly, "Is it difficult to make fireworks?

With that, Qin Yunfei came to the table and took out two different gunpowder samples from his ring.

"I want to know a little bit about the art of making gunpowder, and many people here know a little bit about it. But this is gunpowder designed in different proportions, you probably don't know the difference, do you?"

Qin Yunfei said, and without waiting for everyone's reaction, he used flames to ignite two balls of gunpowder in batches.

And after he ignited it, the first ball of gunpowder had a violent explosion reaction, and "Peng" made a loud noise.

Everyone was taken aback, apparently startled by the sound of his gunpowder.

Especially Zhen Fei was the most surprised, he asked blankly, "When I was in Yancheng, I also saw the old masters make gunpowder, but the gunpowder they made is not as powerful as yours, why is this?"

Su Xinghe, who was on the side, also stroked his beard and asked with some puzzlement, "I also know a little about this gunpowder forging method, but I have never seen such a huge power, can you tell me why?"

Qin Yunfei smiled and said, "You guys will talk about it after reading this." ”

As he spoke, he ignited a second ball of gunpowder.

But after the gunpowder was ignited this time, it emitted a dazzling brilliance with a bang, and there was no explosion sound, and it was still very beautiful.

Everyone was stunned, and Zhen Fei couldn't understand what was happening in front of him, he pointed to the two remaining balls of ashes on the table, "But these two balls of gunpowder, I saw it, the color, taste, and texture are all about the same, how can there be such a big difference?"

Qin Yunfei asked with a wry smile, "Senior Brother Zhen, let me ask you, are you and me the same?"

That Zhen Fei said angrily, "Of course you and I are different!"

But Qin Yunfei spread his hands and said, "But you and I are both human beings." Do you understand what I mean now?"

Zhen Fei was speechless, and didn't know how to respond.

But the people around applauded one after another, expressing their approval of Qin Yunfei's words. What a straightforward reason for this?

Everyone is human, but Zhen Fei is a dual-line Soul Emperor, while the others are single-line Soul Sects. The same people, but the results of the performance, are different.

Even Dean Su Xinghe was clapping his hands and applauding, "That's right! Everyone is the same, but they are different! Could it be that this gunpowder also has such a difference?"

Qin Yunfei smiled slightly, "This is nature. The so-called one nitrate, two sulfonate and three charcoal, although it indicates the proportion of gunpowder. However, the characteristics of gunpowder with different proportions are naturally different. ”

As he spoke, Qin Yunfei briefly described the characteristics of the different ingredients in the black powder and the proportions of the anti-ingredients.

When he finished speaking, everyone present was stunned.

Among them, Su Xinghe slapped his thigh suddenly, saying that what Qin Yunfei told was really convincing.

"I can't imagine that a small piece of gunpowder has so many complex features. I've been researching and innovating for 20 years, and I'm not as good as a young man!"

Su Xinghe's power is in Dragon City, although he is not very tall, but he is also a person with a head and a face. Even if he is not as prestigious as the conservatives of the Divine Machine Academy, the royal family has to give him ample funds every year to develop new Star Soul weapons.

Therefore, his words like this are obviously admitting that Qin Yunfei has real materials.

In this way, the two dragon knights could only glance at each other, and then after looking at Qin Yunfei twice, they stared at Su Xinghe carefully.

"Old Su, are you sure that this kid is not a spy?"

"The two Venerables can rest assured, I know the details of this kid better than anyone else. Definitely not a spy!"

Su Xinghe replied seriously and gave correct instructions for Qin Yunfei's identity.

After receiving such affirmation, these two people were relieved.

They glanced at each other, and when they were about to leave, they also glanced at Qin Yunfei specifically.

"Young man, I see that you have a talent for eating this mouthful. I'm going to give you a direction, too. Don't waste your talent on this beautiful firework. Otherwise, in the end, you will also become an unbearable waste like Yanbeitang. ”

With that, they grabbed the dragon's belly and roared towards the sky.

Looking at their soaring backs, Qin Yunfei was full of emotion.

When will your own thrusters be able to fly into the sky with you?

According to his current progress, if he wants to fly to the nine skies, it will take at least another thirty years.

But with Ling Qi, his plan could be pushed forward by ten years.

Even so, he felt that the process was too slow.

Therefore, after receiving the notice from the Dragon City Divine Machine Academy, he thought of using the school's resources to help him complete this flying plan.

If he could get such a large resource field as Dragon City and the Flying Sky Plan, he could at least push it back for the first twenty years.

Thinking of these things that he hadn't done yet, Qin Yunfei felt full of energy.

And after his popular science this time, the noble children of Dragon City were also polite to him.

The original genius Zhen Fei didn't know what to do at this time.

He looked to the left and no one paid attention to him, and to the right, no one looked at him.

At this moment, everyone's eyes were on Qin Yunfei's body.

"If you can let Lord Dragon Knight give such high praise, this little junior brother will definitely be a character who can influence the entire Dragon City in the future!"

"Don't pretend to be a little junior brother! In the future, you will definitely be no less big than Dean Su! It's not like me and others, you can only be cannon fodder!"

These students, when they think of their future situation, are embarrassed.

These geniuses of the Star Soul Academy were able to get so many resources, in fact, because they had to face two powerful opponents - the Demon Dragon Hall and the Demon Beast.

The so-called raising soldiers for a thousand days, using soldiers for a while, their fate is full of flowers in the front, but the second half has become a gorgeous change.

However, such a gap also makes these people worry about their future.

punishment, they become a powerful existence like the dragon knight, it is possible to ensure that they can survive in the battle.

However, how many of them can become a Soul Venerable peak powerhouse like the Dragon Knight?

Therefore, they envy Qin Yunfei, that is real envy.

At this time, Qin Yunfei's strength has already surpassed Dean Su Xinghe, so wouldn't it be easy to become a big man who will replace Dean Su Xinghe in the future?

So, after being recognized by the dragon knight, Qin Yunfei suddenly became a sweet spot in the eyes of these people, and even that Feng Wanlou hurriedly stepped forward to stammer.

But Qin Yunfei saw Feng Wanlou at a glance.

Qin Yunfei smiled quietly, "Senior Brother Feng, you were so majestic just now." ”
