In the living room of Wang Dong's house, the people who were still eating the fast food delivered by the takeout just now have now sat in their seats with a solemn face.

"Is the physical attack ineffective trait?" Kuroyukihime tilted her head and said, "It's indeed a ...... It's a very troublesome ability, especially for Silver.Crow, whose skills are basically hand-to-hand combat......"

"There is no such thing as invincibility! Otherwise, if the Green King and the Blue King, who rely on direct attacks, don't they be able to defeat that guy if they don't have an artifact in hand? The king shook his head and said, "I have already figured out how to deal with him, but this is not what should be discussed now. ”

"Ah, indeed." Kuroyukihime nodded, shifted his gaze to Arita Haruki, and then said seriously: "Chunxue-kun, although now is not the best time to tell you about these things, it's just that it's better to choose a day than to hit the day, since you have met it, then I'll say it." ”

"Yes! Be all ears! Arita Haruki sat up straight and looked at Kuroyukihime with a stern expression, with an expression that whatever you said was what.

"Chunxue-kun, what do you think...... Why are there such shades as metallic? Kuroyukihime tilted her head and said, "I mean in the acceleration world." ”

"Metallic ......" Haruyuki Arita muttered these three words, and then shook her head inexplicably. said, "Isn't it because of ...... Does metal have a color? ”

"Metal naturally has a color. But don't you think it's weird? What are the characteristics of metals? Most of the defense is high, right? Kuroyukihime shook her head. looked at Wang Dong and said, "The teacher may not know these things, after all, they were some things a long time ago." ”

"I don't know what you're talking about." Renzi shook her head, bit her nails and said, "That looks like it was earlier...... It should be said that it was in the era before the old Seven Kings of Solid Color, right? ”

"That's right." Kuroyukihime nodded and said, "Most of the characteristics of the metallic color are relatively high defense, after all, it is metal-but, have you ever thought about it?" On defense. Originally, Brain.Burst was set to have a relatively high defense of the green type, but in fact, in group battles, most of the metallic imaginary characters played a role that was actually very similar to the green type! ”

Taking a breath and looking at the thoughtful crowd, Kuroyukihime continued, "Metallic colors that are softer or harder than green are also there—but why does Brain.Burst appear in a metallic color that is different from the normal hue? ”

"Uh...... Mutation? Wang Dong tilted his head.

“…… Teacher, please don't sell cuteness at this time. Kuroyukihime sighed and said, "Actually, in the past, there was a theory that was proposed - only for metallic colors - to explain this phenomenon, and that was the 'heartbroken shell' theory. ”

"Heartbreak shell theory?" Haruki Arita repeated the name one more time. Then he asked suspiciously, "Heartbreaking...... Shell? ”

It wasn't that he had discovered anything, just that he seemed to have a slight impression of the name—it was the scene engraved in the memory of the Armor of Calamity. Words that appear to have been spoken by Argon.Array's figure.

"The so-called heartbreak shell theory refers to: some people's heartaches are known to him, such as Renzi's fear of being touched and hurt, for example, Dr. Jun's was once attacked in the throat with a bamboo knife, and Xiaoqian's hope that everyone will go back to the past." Kuroyukihime swept the figures of the three people in turn and said, "So these three people are ordinary hues, but there are some of them, and the wounds in his heart are not even noticed by himself, they are wrapped in a thick layer of 'shell' and pressed to the depths of their hearts - for example...... Chunxue-kun, you. ”

Haruki Arita was stared at by Kuroyukihime, and froze suddenly—indeed, even he didn't realize why he had the ability to fly, and why he became Silver.Crow.

Only, he knew—that ...... It's not an injury that he can't see, it's just a past he doesn't want to recall, he doesn't want to face up. When he was a child, he once heard his parents say they didn't need him......

Looking at Arita Haruki with his head down, Dai Tuowu and Qianyuri invariably stretched out their hands to hold his hand, and then said in unison: "Koharu, we are ......"

"Thank you, Xiaoqian, Xiao Tuo......" Arita Chunxue felt that his nose was sore, and the area around his eyes was inexplicably moistened, making him blink quickly, and then smiled dryly: "I'm sorry...... Senior, you go on. ”

"No, I'm the one who should say I'm sorry." Kuroyukihime shook her head and whispered, "I knew that telling you this would remind you of those bad pasts - but escaping is never the solution. ”

"Yes! I understand. Arita Haruki shook the hands of the two best friends with her backhand, and said with a firm face: "Please continue." ”

"That's what the heartbreak shell theory is -- those wounds that are wrapped in a thick layer of 'something' are invisible wounds." Kuroyukihime whispered, "And not long after, this theory became 'Forbidden. Broken'. ”

"Forbidden. Break...... Why? It's just a theory! Arita Chunxue looked at Heixuehime suspiciously, and Ni Bang didn't have any text [beep-] prison......

"Actually, there is a follow-up to this theory -- not by anyone, but a rumor that naturally began to spread -- and if the 'heartbroken shell theory' is true, then it can be used for practical application." Kuroyukihime shook her head and said.

"Practical application ......?" Arita Haruki looked at Kuroyuki for some reason.

"Do you mean...... Does it mean that the metallic color is artificially born? Renzi suddenly spoke, looked at Kuroyukihime with an incredulous expression, and asked.

"Since a child with a broken heart can be wrapped in a heavy shell that can become a metallic color, then you only need to artificially create such a person with a broken shell, and then let him become an overclocker?" Kuroyukihime smiled bitterly and said, "For example, hypnotherapy." And this so-called 'artificial metal color manufacturing process' was rumored in the early acceleration world. ”

"How...... Maybe ......" Arita Haruki opened her mouth and hurriedly asked, "Then, has this kind of plan really been implemented?" ”
