Liu Lang thought about it, adjusted the air under his buttocks, and sure enough, there was a feeling of floating up in the water. Lao Liu didn't want to perform a "sitting and soaring" on the spot, so he quickly put away his ability.

But he was overjoyed, if he could use this ability to fly, then he would really become a superman. With the ability to fly, you have to be much more agile in your maneuverability.

Haha laughed, Liu Lang gave Zheng Wu a thumbs up: "Well said, reward you." ”

He casually picked up a can of meat next to him and threw it over, Zheng Wu caught it, and said with a smile: "Thank you, brother." ”

Many of the survivors next to him cast envious eyes, although they also distributed food, not everyone could get meat food.

Now in the camp, meat is only supplied to Liu Lang and the people in his inner circle, and most of the other people are distributed pasta, or vegetables and fruits.

Then, another survivor raised his hand and said, "If I can control the density of the air, then I can suffocate people to death!" ”

Liu Lang waved his hand and said, "I also want to get this, the next one." ”

The survivor dropped his hand in frustration.

Tang Ming, who was sitting not far away, said with a smile: "Xiao Liu, it's quite interesting for you to raise this question, I'll talk about it too." ”

Liu Lang knew that he was engaged in scientific research, so he hurriedly pricked up his ears, wanting to hear what Tang Ming had to say.

"Like you said, if the air becomes denser, if it is not restricted, it will be devastating."

"First of all, we need to know what the so-called density is. Density refers to the voids between molecules, the higher the density, the smaller the voids, the more intense the movement and collision of molecules. Therefore, when the density increases, the air pressure increases. ”

Tang Ming gestured with his two hands: "Once the density increases to a certain amount, then the creatures on the ground, all the things that need to breathe air to survive, will die because of the increase in pressure and the inability of the organs to work. You've all talked about this before, but in a nutshell, it's like drowning in water, not being able to breathe, and then..."

"Then, if the density continues to increase and the air pressure increases, the collisions between molecules will inevitably increase, which will cause the temperature of the gas to rise. When the density increases to a certain level, the gas will begin to liquefy and condense, and the liquid state will begin to appear. ”

"Many of the planets we have observed so far are gaseous planets, such as a planet called Glow, the closer you get to the core, the denser the gas becomes, and it is liquid. Moreover, the liquid around the core already has metallic properties, and it is in a metallic liquid state, with a temperature of up to 10,000 degrees. ”

Liu Lang forgot to breathe when he heard this, and when he said this, his ability to mix density was quite powerful. If he could convert the gas in the range space into a liquid metal state by increasing the density, what could not be destroyed at a high temperature of tens of thousands of degrees?

In other words, if the density of the air that constitutes the air bomb is increased to the metallic liquid state, then he Liu Lang will not simply destruct the shell when the air bomb is shot......

"If the density continues to increase, that's the state of the sun. The sun is actually a gas, and it is a gas with a considerable density, and there will be fusion reactions at its core. If the density increases further, the active space between the particles is compressed, and white dwarf matter, black dwarf matter, and neutron star matter appear in turn. ”

Tang Ming said with a smile: "In the end, the ultimate manifestation of density increase is a black hole. In the state of a black hole, the space between the particles is completely deprived, and there is no gas at this time, and it has all been converted to the elementary particle state. ”

The camp was silent, except for the wind blowing and the crackling of wood in the fire.

Liu Lang took the lead and applauded: "That's a great point, Uncle Tang, thank you for giving us a vivid physics lesson." Back then, if our teachers wanted to be as good as you, I wouldn't have failed. ”

A laugh rang out.

Tang Ming waved his hand and said, "Don't don't, I can't afford to wear this high hat." I'll just talk about it, in fact, these are very ordinary knowledge, and any university professor is better than me. ”

"You're so humble, with your level of knowledge, as long as you want, which institution of higher learning won't rush to ask for you." Liu Lang made a big fuss, but this is not nonsense. As an engineer who participated in the Kuafu project, Tang Ming is definitely qualified to be a guest of those institutions of higher learning.

Tang Ming's words gave Liu Lang a lot of inspiration, and also let him know what he could do with this ability.

However, he thought, this ability only limited the density of the air, and he didn't even know if he could get the metal liquefied. What is the state of the sun in the back, white dwarf, black dwarf or something, it is not a matter of direct play, and black holes are not to be considered.

Even if he can get it, Lao Liu doesn't want to make a black hole. What if you suck yourself in?

However, as Zheng Wu said just now, increasing the density to make himself float in the air, as well as Tang Ming's air liquefaction, are enough for Liu Lang to study for a while.

After chatting with everyone for a while, Liu Lang patted his ass and went to test his ability.

Finding a vacant place where no one was around, Liu Lang tried to increase the air under his feet, and after a while, he really got up from the ground. Liu Lang was happy all of a sudden, and said in his heart, Lao Tzu can fly! Haha, I'm going to be Superman!

But soon, he found that he could not fly at all, and at best he could only "float".

Liu Lang patted his head and knew what the problem was. He can only adjust the density of the air, but he can't control the flow of air, so at most, he can only create gas steps in the air to allow himself to walk in the void.

But flying, killing can't be done.

Although it is a bit regrettable, this discovery has made Liu Lang very happy. And, according to this idea, he also developed a variety of uses.

For example, when encountering a difficult opponent, you can directly create air steps under the soles of the opponent's feet, raise the person to a high place, and then release the ability, won't this be able to throw the person to death?

And then there's trapping. Hold a boulder or bomb in mid-air with an air step and disarm the ability when the target passes by....

Lao Liu's mind was lively, and his thinking spread for a while, at least he thought of dozens of fancy plays.

In the end, he wanted to try what the limit of this ability was. Liu Lang took a deep breath, interlocked his fingers, and then began to increase the density of the air bomb.

Unlike last time, when it was only launched with a slight increase, this time, Liu Lang consciously increased the density of the air bomb. So in the dark night, I saw that in the void between Liu Lang's two fingers, a faint point of light gradually lit up.

In the range of the air bullet, the density of the gas rises sharply, and the temperature increases.

All the temperature and pressure are bound in this little bullet.

Liu Lang's head seems to be tightened with a string, and the more his ability is exerted to the extreme, the tighter this string will be. When he felt that the string was about to break, he quickly stopped the air bullet from increasing in density.

With a flick of two fingers, the air bomb that had been filled with shimmer light was launched...
