Overnight, everyone in Dragon City knew that there was a Qin Yunfei from the Divine Machine Academy. He only relied on the strength of the Soul Sect to defeat Luo Longlie of the Soul Venerable.

Because of this, the entire Dragon City Academy freshmen were boiling.

On this day, the people who came to visit Qin Yunfei at the Divine Machine Academy had already lined up from the gate to the front of the main city.

Those senior brothers and disciples of the Divine Machine Academy were standing at the door at this time, helping to clear the crowd.

However, even so, there was still an endless stream of people who came here to visit Qin Yunfei.

At this time, when he was discussing with Lin Feixue how to design the new alchemy platform in the alchemy room, Su Xinghe ran in from outside the door.

This Soul Emperor peak powerhouse was panicked at this time, "Yunfei, Yunfei! someone is looking for you again!"

Faced with such an urging, Qin Yunfei frowned, "Lord Dean, didn't I tell you? ”

Su Xinghe wiped the sweat stains on his forehead at this time, obviously a little scared, "Yunfei, the characters who came this time are not something you and I dare to offend at will." I think it's better for you to meet. ”

Su Xinghe said very carefully, for fear that because of Qin Yunfei's collision, he would offend the big man.

But at this moment, a presumptuous laugh suddenly came from outside the door.

"Xinghe, don't scare this little guy, I'm not going to disturb him when I came to see him today. ”

The owner of this voice is very peaceful, and the tone of his words is also very plain, and there is no high-minded voice. And the most important thing is that Qin Yunfei is still very familiar with this voice.

Qin Yunfei raised his head suddenly, and saw someone coming, "Old Wei?"

At this time, Wei Tianfeng was still holding a golden burqa in his hand, which was very conspicuous.

"That's right, it's so noisy outside now, you can still be calm, you are worthy of the genius chosen by my Wei Tianfeng! Come on, come on, Yunfei, this is the exclusive costume I prepared for you. You try it first to see if it fits. ”

As he spoke, he walked to the alchemy room, and handed the clothes to Qin Yunfei, but when he saw the bottles and cans of things inside, he was dumbfounded.

"Yunfei, what are all the things you have here?"

"This is a test tube, this is a flask, it's used to refine things. ”

Qin Yunfei pointed to the various containers on the test bench nonchalantly, after all, these were the daily necessities of the experiment, so there was no need to care too much about it.

However, what he didn't care about was a big shock to the big man.

"What is this for? With so many crystals to make containers, although you can see the form of refined metal in alchemy, the actual operation value is not great. Why are you doing this?" Wei Tianfeng only felt strange, but he didn't understand at all what this was for.

And as soon as he opened his mouth like this, Qin Yunfei rolled his eyes widely.

"Old Wei, you have not been exposed to future technology, so you don't understand the importance of this basic chemistry. In fact, there are many ways to make gold, but what we are using now is the most inferior technology. ”

Qin Yunfei fiercely criticized Dragon City's refining technology, saying that this was the most backward way.

And his criticism immediately suppressed Wei Tianfeng.

"You said that the alchemy technique that we inherited from the Star Soul Emperor is the last stream? Yunfei, some words I said may not sound good, but this is the case. Your talent is very high, but the talent is high, it does not mean that everything you do can be compared with the greatness of your ancestors. Do you know what I mean?"

Wei Tianfeng spoke very tactfully, he was afraid of scaring Qin Yunfei, but he had to educate Qin Yunfei.

But as soon as he said this, Qin Yunfei shook his head and criticized him more harshly.

"There was once a great scholar who said, I love my teacher, but I love the truth even more! If there is no such courage in this world, how can we stand out from the chaos of illusions?"

Qin Yunfei said, and came to the experimental table, because he knew that just talking and not practicing would definitely not be convincing.

So, he poured a bottle of saturated brine into the flask, and then began to refine the sodium metal by electrolysis.

And Wei Tianfeng on the side, at this time, was still immersed in the sentence "I love my teacher, I love the truth even more" that Qin Yunfei said just now.

Even, when he was recalling this sentence, he even forgot to see what Qin Yunfei was doing at this time.

When my master taught me the three elements of alchemy, I wondered if the difference between charcoal and the degree of heat was the inevitable cause of the metal material. Now that you say that, I feel even more ......."

Wei Tianfeng wanted to say his theory back then, but when he looked up, he saw that Qin Yunfei's flask was glowing with pale green gas at this time, and on the other hand, there was a layer of mercury-like liquid floating on top of the solution.

"This ...... What's going on?Yunfei, what are you doing here?" Wei Tianfeng was puzzled, so he hurriedly asked.

And Qin Yunfei said leisurely, "This is the other alchemy method I am talking about, electrolytic alchemy." And the metal I've made now is a special metal you've never seen before—sodium, a combustible metal. ”

"Burning metal?" Wei Tianfeng looked at the metal in the flask stupidly, and muttered in disbelief.

And Su Xinghe on the side also looked incredulous at this time, "How can metal burn?" Yunfei, don't fool me, if metal can burn, can't the knife be burned to ashes?"

In the face of the ignorance of these two people, Qin Yunfei was reluctant to explain too much, after all, they were still at the ancient witchcraft-level alchemy level, and they had told them too much, but they didn't understand the meaning.

So, just show it and break their original fixed thinking.

So, when he prepared the elemental sodium metal, he first collected the chlorine gas, and then put the sodium metal in front of the three of them.

Lin Feixue had a description of sodium metal in the topic that Qin Yunfei taught herself, but it was the first time she had seen it.

"Yunfei, is this what you are talking about? It looks no different from ordinary silver. ”

Qin Yunfei smiled and said, "You can take it and give it a try, the density of this thing is much lighter than silver." ”

When Lin Feixue heard this, she quickly picked up the small piece of elemental metal sodium, and when she picked up this piece of metal sodium, which was not as big as an egg, her eyes widened in shock.

"Oh my God, is this metal? Can the density of metal really reach this level?"

Her shouting immediately shocked the two old scholars.

"Little girl, show me quickly. ”
