In a narrow room, it will be crowded with three people standing on it. In the center of the room, Yang Xiaoxiao circled around Li Liping and looked around.

"Brother Lang Hua mentioned on the road before: Ability people have a variety of abilities due to the specificity of the individual. When abilities arise from living organisms, they form special sensations in human perception. This feeling is often related to the reason for the ability person's ability, that is, his or her past life experience. ”

When the person in the ability constantly recalls this feeling, the connection between the ability and the body can be deepened. Naming the ability is just one of the simplest ways to pronoun it, and it comes from my own peculiar understanding of this kind of induction. ”

Yang Xiaoxiao recalled, and suddenly seemed to react to something.

She looked at Lang Hua: "Doesn't that mean that we can see the attributes of Ping's ability from the naming of Ping's mother's ability?" ”

"That's true." Lang Hua nodded.

He analyzed: "Bing Qinglian, judging from the naming, should be based on the ice attribute, supplemented by the water attribute and the wood attribute, and the composite ability is a mixture. The therapeutic properties exhibited should be classified as wood and water properties. As for this ice shield, it is probably a reflection of the ice attribute in terms of defense. The ice ability is used well, and it also has a good attack effect, but it is not strong. ”

In the end, Lang Hua concluded: "Then 'Ice Qinglian' is the main healing and defensive ice ability, and the attack attribute is average. As for the healing attribute and the defensive attribute, which of the two is stronger will have to be observed in future battles. ”

Lang Hua didn't say anything, not that he was modest, but that he was really uncertain.

All kinds of abilities in the last days are strange and varied. Even when it comes to the final "ultimate fight", no one has been able to put together an exhaustive list.

In his memory of his previous life, there was no record of the ability of "Bing Qinglian".

Lang Hua only remembered that there were a few simple abilities such as "Ice Lotus" and "Stem Lotus", which focused on healing and defense effects respectively, and "Ice Clear Lotus" should be very similar.

"Is there actually three attributes in Ping's mother's ability?" Yang Xiaoxiao said worriedly, "Wouldn't it be bad if it's too miscellaneous?" ”

Li Liping also looked at Lang Hua when she heard this-after all, ability awakening is related to a person's development in the last days, and it is absolutely false to say that she doesn't care at all.

And in their consciousness, Lang Hua has unconsciously become an authoritative figure.

"Aunt Ping's case is not. Most abilities tend to be very different, difficult to match, and some even conflict with each other, making users miserable. ”

Lang Hua pondered: "But among the elemental abilities, the three lines of water, wood, and earth are originally mild, and although they are distinct from each other, they surprisingly do not interfere with each other, which is a typical example of the perfect coexistence of different strain abilities. Moreover, the ice and water systems are originally homologous, and there will be no interference problems. ”

In fact, conflicts and interference between the abilities of different strains are not absolute.

For example, an evolutionary who unfortunately awakened the dual system of ice and fire.

Two powerful and contradictory evolutionary energies coexist in the body. Not only does it reduce the original energy level of the evolutionary, but in severe cases, it will even damage the host's evolutionary foundation, eventually causing serious injury or death.

But on the other hand, if this evolutionary has luck, perseverance, and perseverance, he will one day be able to separate the two entangled evolutionary energies from each other.

Due to the fact that the two abilities were in tattal confrontation and reacted violently, the abilities were also more violent when cast together.

The strength bonus that the Evolver gets as a result is far from being as simple as one plus one equals two.

However, it is still unnecessary to explain the original situation and the people around him in such detail at the moment.

"It's good if there is no conflict. Is it better at defense than attack? ”

Yang Xiaoxiao muttered, and suddenly wondered: "Brother Lang Hua, I remember that the density of ice is not high, can it be used as a defense?" ”

She recalls some of the things she had learned in class.

"It's not just ice," Lang Hua kicked aside the ice under his feet, "It's high-pressure ice." ”

"High-pressure ice is unusually denser?" Yang Xiaoxiao tilted her head, as if she didn't quite understand.

"These are two concepts." Lang Hua shook his head.

"Density is not necessarily related to hardness, which is the number of masses of atoms or molecules per unit volume, while hardness is related to the structure of atoms and molecules," he explains. ”

"Mercury is very dense, but liquid mercury at room temperature has no hardness to speak of."

"That's right." Yang Xiaoxiao nodded.

Although he Langhua has been a white man since he was a child, he has taught a lot of practical scientific knowledge and theories in the 215th Regiment non-commissioned officer training camp.

For no other reason, mathematics and literature may not be of much use in the last days. However, as a qualified professional warrior in the apocalypse, it is absolutely impossible not to fully understand the new world after the catastrophe from the basic theoretical stage.

Taking practical science, combat literacy, and survival skills as the three first-level disciplines after the war is General Yang's training philosophy. Many of his low-level soldiers also benefited from this, including Lang Hua, of course.

"That'...... Is ice very hard? ”

Yang Xiaoxiao regurgitated Lang Hua's words, but still felt that it was in the clouds.

It's true that she's always been an honor student, but she's only a junior high school student after all.

Even for gifted girls, the knowledge blind spot is still a blind spot.

IQ can only be achieved by people, and knowledge can be exchanged in a limited area. If you think about it too much, it can only be delusional......

"Can it be harder than iron?"

Seeing Yang Xiaoxiao touching her little nose with palpitations, Lang Hua smiled: "I think you should have a deep understanding." ”

"Hmph." The latter lifted his chin and stuck his tongue out at him and grimaced.

"The problem is high-pressure ice." Lang Hua continued, "Metals become brittle at low temperatures because the metal crystals themselves are tightly packed metal lattices, and the atoms are connected by metallic bonds. ”

"Metallic bonds are strong at room temperature. When the temperature is very low, the metal bond can be easily broken. The junctions in the metal crystal become relaxed, so the metal becomes brittle macroscopically. ”

"But ice is different. The hardness of ice increases dramatically as the temperature drops. ”

"Take, for example, ice formed by pure water. At zero degrees Celsius, its Mohs hardness is only 1~2. When the temperature drops to minus 50 degrees Celsius, the hardness of pure ice reaches 6. This has surpassed the average ore and approached the hardness of quartz. ”

"But then the temperature is lowered, and the ice will only grow in hardness slowly. In the end, it is only harder than steel. ”

"Huh? I thought it would end up being harder than diamond. Yang Xiaoxiao said disappointedly.

"What do you think?" Lang Hua reached out and tapped Yang Xiaoxiao's forehead.

"Yang Xiaoxiao, you're just taking it for granted. Although diamond has a hardness of 10 on the Mohs scale, it doesn't look much higher than Dan 6. However, the Mohs scale is not an absolute hardness value, it is only a rough hardness representation obtained by comparing standard minerals with each other. ”

Lang Hua spread his hands: "To put it bluntly, Mohs hardness is a ranking, not a hardness value. Diamond, on the other hand, is a covalent crystal of carbon, and its equiaxed crystal system has reached a geometrically stable state, and its hardness is naturally extraordinary. ”

"Then you also said that the hardness of high-pressure ice ......," Yang Xiaoxiao frowned.

"It's just common ice."

"There are 15 forms of ice that have been identified in the laboratory before the end of the world, and only one type of ice, "natural ice", can exist in nature, that is, common ice. ”

"Although there are many combinations of natural ice in the crystal structure, it is always bound by weak hydrogen bonds between molecules. It is only with the increase in pressure that the lattice structure of the ice changes radically. ”

"There's a saying in materials science that 'structure determines properties.'"

"When the pressure increases, a stronger 'atomic phase' of ice is formed. At ultra-high pressures, 'ionic' ice is formed, which is sufficient to maintain greater strength. ”

Looking at the ice cubes that had dissolved under his feet, Yang Xiaoxiao was surprised: "You mean this ice shield made by Ping's mother with her ice ability?" ”

"That's right," Lang Hua nodded, "Aunt Ping, with the blessing of the spore black mist energy, can mimic such a low-temperature and high-pressure environment in a local area. It's just that once the ability blessing is removed, the high-pressure ice will not stay in the air for long. ”

"The presence of impurities lowers the melting point of ice, resulting in a shorter life of ice crystals. However, Aunt Ping's ability to directly purify water vapor in the atmosphere does not have these effects. ＇

"And as the pressure rises above 2,200 atmospheres, the melting point of the ice increases with the temperature, and it does not melt even at temperatures of sixty or seventy degrees, making it a veritable 'warm ice'. It is also very useful in battle. ”

"But I can't do it right now." Li Liping interjected when she heard this. I still know better.

"Yes, not at this stage." Lang Hua admitted, "But the ability will still grow." This apocalypse will not only bring countless human tragedies, but also make people see more magic and incredible. ”

"Brother, there are some problems with what you said", Yang Xiaoxiao said awkwardly, "Hardness can be used as a reference when attacking." But when it comes to defense, we should also consider strength. ”

"You're pretty careful." Lang Hua smiled and touched Yang Xiaoxiao's head, but the latter shook his head and shook his hand down, obviously still remembering the hatred just now.

Lang Hua didn't care, and continued: "As a tangible body, ice is used as an attack method, and its hardness has a limit. As a result, the Ice Ability will encounter several 'evolutionary bottlenecks' in the mid-to-late stages. ”

"In the final analysis, whether it is attack or defense, the ice system can only be regarded as a relatively mediocre ability attribute. Of course, the increase in combat power brought by the initial stage of the ice ability is still considerable. ”

When Yang Xiaoxiao heard this, she nodded to show that she understood. But Li Liping seemed to be distracted at the moment, her thoughts flew away, and she didn't know where she had drifted.
