"Yes, this is the strange energy that is present in us all the time, and around us, and pervades the whole world, which we call demonic energy. In the most primitive and chaotic state, it cannot be 'seen' by the naked eye, but we can sense it. And through a strange process that I can't articulate explicitly, we are able to manipulate the magical energy into a variety of external manifestations, creating magical and unconventional concrete effects, which change according to the individual's mode and process of manipulation. ”

Li Jie organized the language very carefully, hoping to explain the operation mechanism of this essential energy in his own way, using as concise and clear words as possible, to help Steve further understand what he wanted to express.

Steve listened attentively, and then he pondered for a long time before asking, "What does it feel like?" You just said that you can sense, then it should not be seeing, hearing or smelling, I don't understand what kind of state the so-called sensing is. Also, the various ways of manifesting themselves are not limited to the moving objects that I see now? ”

"The so-called sensing, of course, is not a simple sense of hearing or smell, perception is like an invisible tentacle, which is more three-dimensional and vivid than the sound wave localization of bats. For example, when you close your eyes, you lose sight, but you can still clearly determine that there is such a pencil not far in front of you, and you know exactly where its color and size are facing, and it is more comprehensive and detailed than what you see and hear. As for the way the magic energy will behave after the transformation—"

Li Jie said as he turned his gaze back to the pencil that was quietly floating in the air. Then a fierce red light lit up from the end of the pencil and quickly jumped to the top, in less than a second. The pencil was reduced to trivial ashes, and the smoke dissipated into the air. Only a slight scorching smell remained, proving that it had ever existed.

"It's a bit superficial, but I think it's enough to tell. Generally speaking, individuals are only good at certain tendencies of magical transformation. Different types of conversions, even for us, are just as complex, but they can be done in small areas. Like lighting that pencil. And the transformation that I am really good at has a very different effect. Not comparable. So, is there anything else you'd like to ask? Or, Steve, what do you think this magic is? Why can't humans not only observe it, but also control it? ”

Steve was completely frozen, he was only a few dozen centimeters away from the pencil, although the momentum was not huge, and there was no obvious flame, but it was enough to clearly feel the heat of the moment the light lit up, and even now it was faintly hot in the air.

And all this happened right under his nose, if it weren't for Li Jie specially reminding him that this was a demonstration. He almost thought it was some kind of magic.

He looked up in horror and looked around with a look of surprise: "Bruce, you just said that this kind of magic energy is all around us all the time. Including now? ”

"Including now. But when it is not under our influence and transformation, the magic energy is completely stagnant, and there will be no changes, and it will not actively exert the strange power contained in it to cause impact, so you don't have to worry. Li Jie thought he was afraid that this ubiquitous energy, which he described himself, would lead to uncontrollable results. It can erupt at any time, so it was deliberately explained.

"So. Based on what you have expressed, I think this magical energy can be summed up in the word entropy energy. But Steve, who had obviously entered the mode of surgery and research, did not feel afraid, but slowly became excited after frowning and thinking for a long time. The concept of entropy was proposed by the German physicist Clausius to represent the total amount of energy that cannot do work in terms of dynamics, but it also means disorder in a system. The more evenly distributed any kind of energy in space, the greater the entropy. But in terms of motivation and even other aspects, these energies are not doing work, i.e., as you said, they don't do anything on their own. ”

"According to the law of conservation of energy, heat and work should be equivalent. But we all know that work can be converted into heat, but work generated by heat must be accompanied by the dissipation of heat to cold. It is not possible to take heat from a single heat source and convert it completely into useful work without other effects. For example, we can convert the energy contained in gasoline into the energy of the engine, but this also generates a lot of heat and exhaust gases. No matter how advanced technology is, it is impossible to reduce the wasted energy to zero. To put it in numbers, it is impossible for us to convert 100 heat into 100 work of the same energy level, and in this process, there must be a part of heat that is not converted into work, and this part is what we call 'entropy'. ”

"To put it bluntly – entropy represents disorder and chaos (essentially random motion), and it represents invalid energy. The normal state of any grain is random motion, that is, disordered motion, if you want to make the grain appear 'ordered', that is, purposeful motion, you must spend energy to interfere. Therefore, energy can be seen as a quantity of 'ordered'. And when one form of 'ordering' is transformed into another form of 'ordering', it must be accompanied by an additional kind of 'disorder'. Once the energy exists in the form of 'disordered', it can no longer be used unless new energy is imported from the outside world to make the disordered state back into an orderly state. But this creates a new 'disorder', so that the micro-increase in entropy in an irreversible thermal process is always greater than zero, which is known as the 'law of entropy increase', also known as the second law of heat, which shows that the total chaos (i.e. 'entropy') of an isolated system does not decrease in natural processes. ”

"If we apply the second law of heat first (conservation of energy) to the universe, this typical isolated system, we will come to the conclusion that the energy of the universe is conserved, and the entropy of the universe will not decrease, but will eventually increase until it tends to the limit. In this process, the ability of the universe to further change is getting smaller and smaller, and all the various movements of mechanical, physical, and lifelike are gradually transformed into thermal motion, and finally reach a state of thermal equilibrium with equal temperature everywhere, at which time all changes will not occur, and the universe is in a dead and eternal state. This is the heatdeath theory! But we have not been able to determine whether the heat death theory is true, because human understanding of the universe is far from enough, is the universe in a state of continuous expansion? Is it an unstable thermodynamic model? If yes! Then there is no theoretical maximum for entropy. ”

Steve looked at Li Jie with a full look: "However, you can actually take the initiative to control this entropy energy and transform it into gong that shouldn't have appeared!" It even produces all kinds of magical effects beyond common sense! How is this done? ”

"Can entropy?"

Lee Kit was also fascinated by Steve's depiction of this wonderful state, and fell into deep contemplation, as if something hidden in the depths had been touched and made him murmur. "Go on."

"What is the nature of energy? In physics, this is just a basic concept. We have innate limitations for this invisible and intangible existence. After the establishment of quantitative forces, it was recognized that all entropy essentially originates from the decoherence of quantitative states (Note 1). Decoherence turns the non-entropic pure state into an entropic mixed state, which leads to the conversion of work to heat. Assuming that matter is made up of all kinds of particles, then what is commonly referred to as heat is actually a macroscopic quantity of the intense range of movement of these particles. At finite temperatures, the particles that make up matter are always in an irregular random motion, which is called thermal motion. The more intense the thermal motion, the warmer the object. The reason why heat can be transferred from one place to another is that when the particles in vigorous motion come into contact with the particles in slow motion, the energy of the movement will be transferred from the violent particles to the slow particles through collisions, so it is manifested as heat transfer from a high-temperature heat source to a low-temperature heat source. ”

"If we follow the Standard Model, then we can assume that the elementary grains are made up of species—particles A that make up matter but do not carry energy, such as the elementary grains that make up plasma, and a particle B that carries energy, various light, heat, or forces, and we can even assume that such grains themselves are energy; The first is the Higgs Bose, which they call the 'God particle', the intermediate medium particle C that connects the matter particles with the energy particles. But as for the energy b, which is already a basic grain, why there are various manifestations such as light and heat, I can only say that this involves not only physics, but even philosophical logic, which is one of the ultimate problems of the universe, and perhaps only God knows. ”

After experiencing the initial excitement, Steve found that the more he reasoned, the more he didn't know and the more difficult things he understood, and his expression became depressed.

Note 1: Decoherence, colloquially known as 'wave function collapse effect', is one of the fundamental characteristics of measuring force. The orthodox Copenhagen interpretation of measurement holds that human subjective observation affects the objective existence of microscopic entities. The classic example is "Schrödinger's cat". To put it mildly, the decoherence effect refers to the fact that 'when no one is looking at the moon, there is only a certain probability that the moon will hang in the sky; And when someone takes a look, the original uncertain existence of the moon suddenly becomes reality the moment people look at it.
