The fabric was sewn by a specially invited tailor and tied with ropes. Pen & Fun & Pavilion www.biquge.info

For the first time, the craftsmanship was rusty, and no matter how good the design was, it was a messy feeling of patches and patches.

However, the basic shape is still available, and the configuration is complete.

As if flying a kite, two soldiers propped up the annular umbrella circle of the air intake, and one of the mages followed Liang Kai's request, blowing the wind into the umbrella cover, gradually rounding it up and full.

Thank you that this is a magical world! The manpower blower is on call, otherwise it is really not easy to hold up.

The balloon with a diameter of three or four meters gradually rounded and slanted, and then Liang Kai inserted the source crystal under the umbrella circle, activating the magic lamp.

Blazing balls of light illuminate the square. Everyone's eyes were squinted in a sting.

[Wait!] Suddenly, someone in the live broadcast room shouted, [There's no need to try, it's impossible to succeed!] 】

The highlight is at the top, and it is an expert speech.

Look at the name again, Sheldon. Apparently it was changed because of the worship of a certain scientist, and the origin is known to everyone all over the world.

This guy is the guy who clamored to watch a love action movie in the live broadcast room two days ago and study the behavior of xxoo in the other world, which is impressive.

Later, many netizens checked this guy's information and found that he was Chinese-American, but he was not surnamed Xie, but Sheldon was his English name.

This guy went to college at the age of 11, got a PhD from Stanford at the age of 15, worked at the Lawrence Berkeley National Laboratory for several years, and then went to CERN.

The trajectory of this life is really similar to Sheldon, and even because he gave birth to a new word......

[Funny beauty, why can't you succeed?] Some netizens asked curiously.

That's right, it's funny beauty, oh, Chinese beauty.

As he spoke, the magic lamp had been placed in the umbrella circle, and at the same time, the mage stopped blowing at Liang Kai's request.

And then...... The balloon began to skew, leak, and tip at a speed visible to the naked eye......

Fortunately, the umbrella holder reacted quickly and jumped out with a magic lamp. If you let the lid fall into the lamp, it will burn.

[It's a heat exchange!] The magic lamp is bright, but do you feel the heat? 】

I was stunned for a moment. Liang Kai shook his head. It's not really hot.

"But if you put your hand in it, you will get burned......"

[The internal energy is high, but there is no heat exchange.] If there is heat convection, you should be able to see the air distorting like a fire above...... You're moving it around at random, and you don't feel any heat at all, and the radiation and conduction are obviously very poor. 】

[The principle of this magic lamp should be similar to vibrating air molecules, heated to a high temperature ionic state. There is also no sign of stimulated expansion of the air when the light is turned on, and it may be that the air particles are locked and the density does not change. 】

[Tut-tut, the Maxwell demon has been realized like this, it's so unscientific! ] Sheldon ended his lecture with a sigh.

What the hell is Maxwell? 】

[Except for Maxwell's demon, you know the rest? 】

[I really returned everything I learned to the teacher, 2333......]

[Sure enough, the college entrance examination is the pinnacle of my life's intelligence! ] 】

The live broadcast room was noisy, noisy, and noisy, and in the end, a group of Zhihu experts and big V stood up in time and urgently popularized science, so that everyone roughly understood what was going on.

There are three ways of heat transfer, conduction, convection, and radiation.

Hot air balloons need to have a heat source that emits heat to heat the air in order to fly. But this magic lamp isolates all heat transfer methods, and converts almost all heat into light, similar to the earth's energy-saving lamp, the light is not hot...... How to fly?

As for Maxwell's demon, it's Maxwell, and it's the thought experiment proposed by the guy who wrote Maxwell's equation. Suppose there is a very small sprite that can distribute particles of random thermal motion into a certain phase lattice according to a certain order, then the second law of thermodynamics is not accurate, and a perpetual motion machine can be generated.

The latter is not paid attention to, and if you do, you may not be able to understand it, but the first half ......

【Lying rubbing? Like energy-saving lamps, it is so scientific? It's so unscientific! 】

[6666, I feel the need to revisit the Otherworldly Tech Tree.] 】

Tsk, won't magic lamps work? Liang Kai frowned.

The Group of Experts is also discussing-

[In this case, either the magic array is changed, and the change has convection conduction; Either change the formation, change to one with convection conduction, such as a fireball ......]

[No, there is no air distortion like the Fireball Technique, there is no radiation conduction, and it seems that it will draw air when it is launched.] During the island war, a fireball can boil the seawater of the fish-man's protective body, which is estimated to have a lot to do with the condensation and compression of heat. 】

[Maybe it's the Blue Boundary water that's lower than heat, right?] 】

[Or, do you remember that the god clone was more watery, and the water in the entire sea became non-Newtonian.] The viscosity can be changed, and the specific heat can also be changed, right? 】

[I suggest that you first determine the energy contained in the source crystal by measuring the intensity and duration of the magic lamp...... You must know that the energy of one kilowatt-hour of electricity is not much different from the equivalent of Tnt, but if one kilowatt-hour of electricity is bright enough for a few minutes, TNT will be consumed in half a second. 】

[The energy utilization rate of this magic lamp is extremely high, indicating that the stored energy may not be as much as expected.] It's not cheap, is it? If the energy is insufficient, it is difficult to support the balloon to hang in the air for a long time......】

[There is a prerequisite for determining the source crystal energy...... Conservation of energy. Are you sure the world follows the laws of thermodynamics? 】

[It should still be conserved, right?] It's too easy to bug if it's not conserved, and the void is alive, and it's impossible to imagine that there will be a stable world born......]

Experts, you say a word to me.

As for the netizens, they are even more confused-

[What, what, what is this talking about? 】

【Specific heat?】 Non-Newtonian fluids? One kilowatt-hour electric and TNT equivalent...... Ahh 】

[Focus, pay attention to the point! I mean, island wars? Fish-people? Protecting the body of seawater? A doppelganger? Oh my God, what the hell did we miss yesterday?! 】

Each has its own words, and there is no consensus.

Liang Kai smacked his lips and looked at the two secretaries and the patrol soldiers: "Have you received your things?" ”

Since the first solution doesn't work, and it takes a lot of effort to fix and add, let's just try the alternative.

Several people looked at each other, looking at each other.

When asked, Liang Kai did not receive the oil named.

That's right, the Atlas also has oil, similar to the earth, from animals and plants, which can be burned and eaten. There is no magic, and it is possible to use the traditional ignition method.

The reason why you don't need to come up is that the magic array is lighter, more durable, and more forced!

"The chief officer of the treasury said that oil is a war preparation material, and now the mountain city is so critical that it cannot be used easily."

That's not bad, swords, bows and spears need to be maintained with oil, demon attacks can be sprinkled with oil and fire, and many braids need to be soaked in oil to increase toughness before they can be used......

It's just that Liang Kai has been instructed by Sanfan to develop new equipment, and it is said that one or two barrels of oil should be fine.

As for the oil stove, I received it, one person is more than high, two or three people are wide, and the big ding is such a majestic giant furnace, and it took a lot of effort for several people to move here. At that time, Liang Kai wondered what they were doing, and his feelings were oil stoves......

[Lie down, if this thing can go to the sky, the hot air balloon will really go to the sky! ] 】

[Brother Bo, your emotional intelligence is low, right? ] I don't stuff money when I get things, and I send people to go, but I don't come to the door in person, I don't have sincerity at all, and it's strange for people to give it to you......]

[Damn, just now, why did you go early! ] 】

[How did I know that the people of the other world have the same virtue as us? 】

Liang Kai was speechless when he listened, and pondered carefully, it was really this reason.

The Xingxi treasury is not far away, just below the star tower. This is the urn wall behind the star tower.

At the moment, I counted which materials were received, which ones were not, and which ones were of unqualified quality, and then Liang Kai took a few people, carrying new account books and a number of rebates, and walked in person.

However......

"I'm sorry, you want these things to belong to war materials, and they will not be supplied in extraordinary times." The chief officer looked at the sky and said with a contemptuous expression.

It's useless to wear out the skin of the mouth, and it's also hard to stuff money. When I asked him what he really wanted, he was answered, "What do you mean?" I am an upright person and do things seriously, is there a problem? ”

[It's not about money, and it doesn't seem to be about attitude. 】

What can I do......

Netizens followed suit.

[Why don't you go find the speaker?] 】

[Just kidding, that's it? 】

[Tsk, it's really Hades good, the little ghost is difficult. 】
