Charles gave them a large sum of money for daily use, and as a result, the other two bought nothing except some paper, pens, and paints for Tilby's house.

However, today Liao Xington helped Charles buy a lot of food and came back, which moved someone who had eaten dry food for a few days to tears.

"Thank you!" Charles reached out and took a cup of yogurt that was still warm, the wound on his finger that was already deep and visible was half healed.

The microorganisms in this world are a bit ferocious, and milk is not easy to preserve, so if it is stored for three to five days and transported, it is generally made into yogurt.

The main thing is that the food preservative that Charles and his family rely on to make a fortune is a little sour, and the taste of yogurt is just enough to mask it.

Of course, don't count on lactic acid bacteria to regulate the intestinal flora or something, and the more ferocious preservatives kill them along with other bacteria and microorganisms.

In some cases, Charles's preservatives can even be used to clean wounds to prevent bacterial infection.

However, this preservative is slightly toxic, a small amount of food is fine, a small amount can kill intestinal parasites, a large amount of ingestion in a short period of time will be dead.

"You drink slowly. "I also bought other food and came back, and the bread will be baked later." ”

Charles was about to burst into tears, and Tilby hadn't thought about getting him food in the first place.

After he finished drinking the cup of yogurt, Liao Xington sat on the edge of the bath, reached out and scooped up a handful of water and slowly poured it on the wound on his skull, and asked, "Why did it hurt so badly this time?"

Charles smiled bitterly, he was blown up just now and couldn't release his shield. I'm still blindfolded, and I can't even release the healing technique.

He recounted what he had just experienced, and then asked, "Why did the elements explode when I did that?"

Liao Xingdun continued to help him scoop the potion from the pool on his head to treat the wound, and at the same time said: "This is a long story, you should not understand it if it is too profound. ”

"My sister is the best at this, and he used to blow everyone up enough. ”

"Since you asked, I will briefly tell you that you remember the following points. ”

"The basic elements remain at rest until an external force forces them to change their properties. ”

"The change of activity of the base element is directly proportional to the force, inversely proportional to the quantity of the base element, and proportional to the reciprocal of the amount of the base element; ”

"The action and reaction forces between two active elements interacting are always equal in magnitude and opposite in direction, but the rate of annihilation of the active elements varies according to the nature of the element. ”

"The internal energy of an active element is equal to the sum of the energy transmitted to the base element from the outside and the work done to it by the outside world. ”

"Internal energy can be spontaneously transferred from high-energy elements to low-energy elements, but it is not possible to spontaneously transfer from low-energy elements to high-energy elements. ”

"You study these things thoroughly, and then proceed to the next step, and I'll bring you bread. ”

The bath fell silent, and Charles pondered intently what Leoxington had just said.

The first one is easy to understand, what he calls "Dao" Liao Xing Dun is called the basic elements, and these basic elements have become all kinds of magical elements under the action of the power of nature and spiritual power.

The second one he had a headache, what was the "activity" of the element itself, he hadn't heard of it. He knew that the power of the magic array was directly proportional to the speed of elemental movement, but what Liao Kexingdun said was obviously a more microscopic level. He could understand the nature of activity, which should be the attribute of the magic element.

The elemental annihilation of the third article is not difficult to understand, and the relevant knowledge is often used in spell warfare and compound magic, but the phenomenon and principle of elemental annihilation at the micro level is a research gap.

When thinking about the fourth and fifth points, Charles suddenly had some inspiration about whether the internal energy of this active element is related to "activity".

Having gone through these points in his head, he recalled what he had just done again.

A ball of potion in the bath was wrapped into a ball by his spiritual power and floated in front of him, and under his control, the surface of the water balloon moved violently, with layers of folds in some places, spikes like hedgehogs in some places, and smooth as a mirror in some places.

This is an extremely crude model of the wind element that he simulated, and if you zoom it out, the whole model expands and contracts at a specific frequency, and when you zoom it in and look closely, you can see that there is a regular movement everywhere.

Then he created a second water ball, which had a smooth surface and floated there motionless, a model of the basic element.

What he just did was to use an external force to force the wind element with an irregular surface into a basic element with a smooth surface.

"The internal energy of an active element is equal to the sum of the energy transmitted to the base element from the outside and the work done to it by the outside world. ”

This sentence suddenly flashed in Charles's mind, and what he did just now was not to do work on an active element.

Under the influence of his own spiritual power, the internal energy of that wind element increased.

And because the activity of the elements is directly proportional to the force.

From this, it can be concluded that the "activity" of the wind element is directly proportional to the amount of internal energy, and perhaps the "activity" is a measure of the amount of energy in the element.

It can be seen that when the external force acts on the basic element, first of all, the basic element becomes a certain active element under the action of the external force, and has the initial internal energy; then the external force continues to do work on the active element, and the internal energy of the active element increases; when the internal energy of the active element exceeds a certain level, that is, the activity of the active element exceeds a critical point, the active element explodes.

Thinking of this, Charles couldn't help but complain in his heart, this basic element is a tire in the zodiac, and it will explode if you pump too much.

It's just that at this time, he found another problem, what is the situation of the demon-breaking divine power?

Previously, it was believed that the demon-breaking divine power was to forcibly stop the magic elements in motion, causing the magic array to fail, but later it was discovered that it actually eliminated the magic elements.

If you look at it this way, could it be that the demon-breaking divine power is to eliminate the internal energy of the active element, so that the activity of the magic element is cleared, and the gas in the tire is discharged?

Charles's demon-breaking powers were sealed at this time, and he decided to go out and find Freya to study it carefully.

One problem is not solved, and another problem arises.

When the wind element exploded just now, in addition to the shock wave, his spiritual power and soul were affected, which showed that the nature of the energy exploded in the wind element was a bit strange, maybe it was not a single type of energy.

He decided not to think about it for now, and then he could think about how to use this energy.

Just now a small wind element can blow him up like this, if you store a large number of magic elements whose activity is close to the critical point, and then exert external force to detonate it when needed, this power is really terrifying.

There is also the internal combustion engine, if it is no longer a magic array, but uses this elemental explosion to push the cylinder, the efficiency will be much improved.

At this time, the smell of incense came, and Liao Xingdun walked into the bathroom with a basket.
