"Miss Xie San, we will do our best in the future. ”

Before leaving, several ladies thanked them a thousand times.

But looking at their distant backs, Lin Feixue didn't know what to do next.

"Can this really be done?" Lin Feixue still didn't believe Qin Yunfei's decision this time.

Qin Yunfei smiled freely, and his confidence was already self-evident.

"Don't worry, within a day, the entire Wind and Snow City will spread. ”

Looking at Qin Yunfei's confident expression, Lin Feixue's heart was full of mixed tastes.

She wanted to ask again, but before she could speak, she was dragged home by Qin Yunfei.

Back in Piaoxue Pavilion, Qin Yunfei went into the study alone, leaving Lin Feixue, as the master, alone in the hall.

Holding the teacup, Lin Feixue looked at the door of the study with a dull expression, and she suddenly felt that Qin Yunfei at this time was so unfamiliar.

But looking back on the time when the two met, I felt that there was nothing wrong with it.

Qin Yunfei, who could take out the pattern of roller skates, didn't he come to him with a mysterious and unpredictable attitude?

The four weapons that were created later were even more astonishing, and even moved his father, so that he had a concession in his marriage.

Suddenly, Lin Feixue shook her head suddenly, "Oops, Lin Feixue, Yunfei has never harmed you, how can you speculate about him like this?"

With all this, Lin Feixue didn't know how to guess Qin Yunfei's identity, and she was even more reluctant to guess.

With such persuasion, Lin Feixue looked at the study curiously, "What kind of things will he make this time?"

Just when she was so puzzled, Qin Yunfei suddenly pushed open the door of the study, holding a drawing in his hand, and proudly gestured a "scissors" hand in a victorious posture.

When Lin Feixue saw this gesture, her face suddenly showed excited ecstasy, she stepped forward in three steps and two steps, grabbed the drawings and looked at them.

But with the drawings, she couldn't understand what was drawn on them for a long time.

"Yunfei, what are these things you painted?"

Lin Feixue looked at these strange patterns in front of her very strangely, she swore that none of the things in them had ever been seen before, and even the difficulty of design was better than that of roller skate parts.

Qin Yunfei took the drawings back with a smile and pointed to the drawings on them, "Today and tomorrow, the two of us have to be busy for a while, this is called electronic components." Do it well, and you'll get an unexpected surprise. ”

The thing drawn on this is nothing else, it is a simple signal transmitter and the construction of various electronic components.

These include diodes, capacitors, resistors, and more.

Seeing the resistance, Lin Feixue can still roughly understand a little, capacitors, already a little confused, when he saw the electronic component of the diode, Lin Feixue was really confused, so he asked Qin Yunfei.

"Yunfei, what is this diode? Why have I never heard of it?"

Qin Yunfei didn't know how to explain to her, and after thinking for a long time, he said, "This thing is actually similar to sand." But you need to do a secondary process, you just need to make me a thin gold sheet now, and I'll take care of the rest. ”

"Oh...... Then I'll build it for you first. ”

Lin Feixue reluctantly looked away, but Qin Yunfei could clearly see her thirst for knowledge.

"Don't worry, it's done, it's already in duplicate, one for each of us. In order to appease Lin Feixue, Qin Yunfei smiled and comforted her.

When Lin Feixue heard that it was done and that she had her own one, she immediately burst into joy, clapping her hands and jumping happily, "Okay! ”

So she picked up the hammer and tongs, and clanked beside the stove.

Qin Yunfei on the other side found the remaining quartz material from before at this time, and began to use charcoal fire to polish it.

The wireless signal transceiver is the earliest electronic device manufactured by human beings and is also the ancestor of the telephone.

At this time, Qin Yunfei was preparing to go to the Warcraft Mountain Range in the future, if he arrived at the Warcraft Mountain Range, if the distance between the two was too far, the contact would become a problem.

If you make a walkie-talkie of 500 meters, it can ensure the smooth flow of information between the two, so that even if you really encounter something, you can also encounter difficulties.

However, without the equipment and instruments of that world, using the most primitive alchemy equipment in that world to manufacture diodes, it really embarrassed Qin Yunfei.

He was a perfectionist, and in that world, diodes were made so fast that they could be the size of a small fingernail.

But at this time, with this kind of equipment, even if Qin Yunfei racked his brains, he could only achieve the size of his thumb.

However, when I think about it, it is enough to achieve this size, and the demand is not large, as long as the size of the casing of the walkie-talkie is easy to take.

Qin Yunfei wiped the beads of sweat from the corners of his forehead, but saw Lin Feixue looking at him with glowing eyes at this time, and handed over a towel.

Qin Yunfei was startled, took the towel, and thanked him, "Thank you......"

Lin Feixue picked up the diode made by Qin Yunfei, looked at it again and again, and asked curiously, "What is the use of this thing?" It looks like a small glass bead. ”

Qin Yunfei didn't know how to explain it to her, so he simulated a thundercloud and let the current flow on the diode.

When the current flows, it already emits a dazzling purple light.

Lin Feixue exclaimed, "What's going on, there is obviously no star soul power fluctuation in this, how can it emit such a bright brilliance?"

Qin Yunfei explained, "This is actually the tip discharge in the semiconductor, the refraction of light. It's simple, but that's just the beginning. By the way, are you ready?"

Lin Feixue hurriedly took out the thin gold sheet and handed it to Qin Yunfei.

"Well, that's it, take a look, is the thickness and size appropriate?"

Qin Yufei took the thin gold sheet and took a look, but saw that the thickness was not as thick as a fingernail, only one centimeter wide, and one zhang long.

"yes! That's it! That's it! Blizzard, you're awesome! I'm going to assemble the gear now. You wait for me. ”

To tell the truth, Qin Yunfei rushed into the study, picked up the wooden box he had prepared earlier, and began to renovate the wiring.

Lin Feixue saw him so excited, and knew that this thing was estimated to be more complicated than so many things made before.

In this way, she suppressed her curiosity, and said, "Then I will first inquire about the use of those ladies." You get busy at home first. ”

"Okay, when you get back, the things will be packed. I'll surprise you when the time comes!" Qin Yunfei's attention was completely focused on the hand at this time.

Seeing Qin Yunfei so serious, Lin Feixue was a little entangled in his heart, on the one hand, he appreciated Qin Yunfei so seriously, and on the other hand, he snubbed his own loss in order to forge equipment.

But no matter what, she finally left the Drifting Snow Pavilion, because she knew that this man was trustworthy in her life.
