Robier found the "air conditioner" in the old Lei Zhe's study and pulled the line directly from it, this force is not small, this is also the trouble place, when the energy passes through the energy line, the energy line will be tightly combined, under normal circumstances, the thin woman may not be able to pull the tightly connected line.

Lei Zhe got up and walked behind Rober, he wanted to see what was so special about this, these two joints together are a sphere, as for what materials are made of, I'm afraid only the people in the craftsman department know, but since it can be made, mass production is definitely not a problem, this Lei Zhe still trusts the craftsman department very much, these people will not invent something boring.

Under Reizhe's gaze, Robier simply fixed the hemisphere to the original energy line, and the other to the air conditioner.

"Does this thing provide energy?" Reich wondered, as the material didn't look like it was made of energy metal, and if it wasn't energy metal, it wouldn't have been able to transport energy at all.

"My lord, this connector is made of energy metal and some other metals, because considering that the energy output of the household is too large, it is difficult to unplug when not in use, although the switch is designed, but if you want to move the position, there will definitely be all kinds of inconveniences. ”

Lei Zhe nodded, this is the reason why plugs and sockets exist, because the placement of furniture cannot be set in stone, but the current Rost does not have so many places that need energy, if the energy can be directly convected into electricity one day, then what will become of this world Lei Zhe dare not think, as for the conversion, it is absolutely possible, but how to do it, the current scientific and technological strength of the craftsman department is obviously not enough.

"Demonstrate what it can do. ”

Robier nodded, and the two hemispheres came together, and then the air conditioner released the cold air again, which was similar to the plug, and Robiel pulled the air conditioner again and stopped running.

Seeing this item, Lei Zhe was not too happy, because this design is just a simplified plug in short, but it can be regarded as an improvement, if it is in the era of the earth, making such an easy and simple thing will definitely make a lot of money, and a few guys in the craftsman department are not in vain.

"Is this easy to make?"

"My lord, this thing is very simple to make, and it can effectively control the energy input, the energy through this sphere will not be as constant as before, this amount will be reduced to the amount used by the air conditioner, so that the air conditioner will not be too cold, and the energy input size will be changed by rotating the ball to control the temperature, or the size of the flame.

"??? still have this kind of function?" Lei Zhe was stunned, this is a special switch, looking at Robbier's eyes are a little wrong, these people can really be described as geniuses, by changing the size of the energy to control the cold air sprayed out, or the flame sprayed by the stove, of course it is very simple, but it is a troublesome thing to do, this energy is different from electricity.

He has basically no laws to speak of, and naturally the control needs to be more troublesome.

"Well, this feature was come up with by my son. ”

"Haha, that guy is pretty good, but let's experiment with the specifics. Lei Zhe smiled and said with a smile, Rost's energy naturally can't be free all the time, and if you want to charge it, you have to follow the table without statistics, and the only way is to limit the time period, which is a problem that will only appear after the subsequent development, when all people have income.

If you want to earn back these incomes, this is undoubtedly a must.

Robier nodded, and directly began to rotate the sphere, Lei Zhe looked at it carefully, and there was indeed a mark on it, and it was very fine, there were five levels, it was not troublesome for the hemisphere to rotate, it was a bit like a magnet, but Lei Zhe knew that it was not a magnet, but the energy fell in the moment of circulation, and the two hemispheres were adsorbed together.

If you just look at the air conditioner, you can't see the change, Lei Zhe closed his eyes and felt it, as Robier turned the sphere, the magic array released more and more magic power, and then the release of small magic began to get smaller, Lei Zhe opened his eyes and smiled: "Very good, you tell your kid, hey will reward him." ”

Robier nodded, not only was he not scolded but praised this time, he didn't expect it, he thought that Lei Zhe wouldn't care too much about this joint invention, after all, for him, this kind of joint invention does not seem to be of much use, and this thing was originally made as a small thing.

"If you don't have anything else to do, go back first, I'll naturally go to the craftsman's department to have a look when I have time, and you can stop for the time being about the track, I'll rethink that thing, with Rost's current ability, it's really not right to think about it so far." Lei Zhe thought for a moment and then said, Kaseban is still too far away from Rost.

If you really want to go directly to Kasseban, this road is full of dangers in the past, and it is impossible for those monsters on the train track not to be interested, and being attacked by some large monsters will only increase casualties.

The matter of building the track can't be rushed yet, Lei Zhe also thought about it a little bit of a matter before, and felt that he wanted to establish a deal with Kasaiban, or directly occupy Kasaiban one day, and if the two cities were to be connected, they still had to go through the train track, in fact, this world was not too suitable for train tracks, and this world was very dangerous.

There may be a variety of Warcraft in the long-distance journey, and these Warcraft have a desire to attack humans, so the main means of transportation in this world is still based on airship portals, and secondly, if you have the strength, you can choose horses or Warcraft to rush, but this is not very convenient.

After all, airships and portals are still the mainstream, if you want to follow up on development, you can get a transport plane, but the price of that thing is not cheap, even if it is cheap, it is difficult to get it in his identity, not to mention that there is no way to train qualified pilots, that thing is also chicken ribs, if you want to fly normally, you still have to capture flying monsters, and then open monster breeding.

"Yes, sir. Robier nodded, he really didn't have anything to look for Lei Zhe, but what happened today still made him feel surprised, but he was even more grateful to Lei Zhe in his heart, and before he knew it, Robier's loyalty rose again.
