Xia Mi propped himself on the low table with one hand and squinted at Li Su who was standing aside. "What are you doing?"

Li Su didn't answer her, and after a moment he waved his hand, and a small building rose from the ground.

Seeing his work, Natsumi pursed his lips. "You...... It's definitely a science student. ”

It's no wonder she thinks so, in fact anyone who sees this building will doubt the designer's aesthetic. This is not even a building, it is more like a super large cube with a length and width of ten meters, but there are some openings on the surface, which look like windows and doors.

"I'm sorry I don't have an art cell." Li Su waved his hand again, and a spiral staircase snaked up next to the cube.

"Take your pick, I'll get you the iPad."

"Are they all the same? Then it's the top floor. Xia Mi walked up the stairs, and Li Su followed.

Push open the door on the top floor and you'll have an unobstructed view of the interior of the room. There is only one room and one toilet on this entire floor. The room was empty except for the low table in the center.

Li Su sat directly on the ground, took out a pen and paper and handed it to her. "I'll leave it to me when you've written the interior layout or something, now would you mind giving me a little more knowledge?"

"For example?" Natsumi sat across from him.

"For example, all kinds of knowledge of the dragon family."

"I don't mind, but I can't."

"What do you mean?"

"Looks like you don't understand anything." Natsumi sighed. "Have you ever thought about a question? If you take your stem cells to grow another you, is there a relationship between the two people? ”

"You mean......." Li Su vaguely understood something.

"And that's not all. Power is transmitted through bloodlines, so theoretically each prime-type breed has three cocoons to exchange with other primordial species, and the Black King can be mass-produced. But after all this time, I'm still the first generation, am I? ”

"yes."

"So." Xia Mi spread her hands, "'Cocoon' is actually more like a stand-in technique. It was empty before the death of the first generation, and the power of the first generation flowed into the 'cocoon' after the death of the first generation before it really took shape. As a medium, carrier, and guide of power, a very small part of our souls will be sealed into a cocoon. ”

That is to say...... In fact, the dead king is really dead? Li Su asked.

"Yes, and the main part that remains is emotional. For example, love, anger, joy, and despair, but most of the time we keep affection. Family affection has been passed down and refined countless times, making it difficult for us to forget. ”

"Isn't this just a container?" Li Su sighed. "By the way, this is your brother." Li Su took out the cocoon and threw it over.

"Yes, we're just vessels of power." Natsumi caught the cocoon and put it aside, her voice a little flat. "Even more desperate is the moment of awakening. You will feel the deep emotions that accompany the power, and the chaos is like numbness. That's when you doubt everything, feel like everyone around you is cheating on you, and you don't even know who you are. ”

"It does sound miserable." Li Su nodded. "So ......"

"So every generation of the first generation has to be re-learned, I can't help you."

"Uh...... Shouldn't this be the case where each generation buries a scroll and then lets the next generation find it? Li Su suddenly asked.

"Yes, there were." Natsumi remembered something. "For example, the ossuary you found containing Norton and Constance Dante, which is carved into this kind of thing. But in order to avoid the spread of knowledge, it was carved by him with his own password, which I can't read. ”

"So how can he read it? Doesn't he have to learn the language again after the cocoon? Or does the soul as a medium also include language? ”

"It doesn't include that much." Natsumi shook her head. "But that can include the way the password is reasoned."

"Okay...... But can you be of some use if I save your life? Li Su supported his forehead.

"Maybe." Natsumi thought for a moment. "Where are we?"

"My Nibelungen! Don't look down on you just because you're smaller, bastard! It's growing! Li Su felt that his strength had been provoked, and slapped the table angrily.

"No, it's not the Nibelungen."

Li Su fell silent. After a while, he put his hands to his ears and made a horn motion. "I might ...... Did you hear it wrong? ”

"Then I'll repeat." Natsumi took a deep breath. "It's not the Nibelungen."

“What？！！”

"Do you remember the first time you entered the Nibelungen?"

"Remember, it's depressing."

"Because you are not the 'dead', of course you feel this way when you go to the land of the dead as a living person, do you feel this way here?"

"Like...... No. ”

"That's right."

"That'...... What is it? "Li Su is a little crazy.

"How do I know?" Xia Mi looked like she didn't care about herself, and there was actually a hint of schadenfreude in her words.

Li Su, who was still frantic just now, suddenly changed his face, stood up with both hands, strode to the window, and jumped down.

Xia Mi couldn't help but be stunned for a long time when he saw his smooth movements, and after a while, he realized that this was the height of the third floor, and quickly stood up and went down the stairs to see what was going on.

Li Su was squatting not far away, as if he was holding something in his hand, and his face was solemn. When Li Su left, she scouted the space, which was supposed to be the border.

Li Su suddenly understood a little bit of what Xia Mi said about 'doubting everything', because of the things in his hands.

It was a piece of parchment, a little yellowed and curly, with a line of black ink on it. What made Li Su frown the most was that there were several blood spots in the lower right corner.

"What's wrong?" Natsumi walked up behind him.

"Remember what I told you about growing up in this space?" Li Su didn't look back.

"Remember, and the Nibelungen doesn't grow up." Xia Mi said.

"Maybe I'm not right, it's more like ...... Assimilates the space around it. And there is this in the space that has just been assimilated. ”

Li Su showed Xia Mi the words above. It was Latin, and Latin was the main subject at the Kassel Academy, and they could all understand it. Seeing the above content clearly, Xia Mi also frowned.

The line reads "Filii autem Orbis Terrarum", which means, "son of the world".

"Do you have anything to do with it in your remaining memories?" Li Su asked.

“...... No. After thinking about it carefully, Natsumi replied in the affirmative.

——————————————

The two discussed for a long time but did not get an answer, so they had to give up. Li Su returned to the real world alone, and he still had an appointment.

Take the familiar subway again, sit at Wangfujing Station, leave, and go back to the ground along the stairs. It was completely dark, but the ground was brightly lit.

Brightly coloured Christmas trees and reindeer motifs are affixed to tall windows, and the lights in the windows glow a soft green or brown glow through translucent stickers. Christmas songs echo across every street, and smiles are bright on every street.

In the middle of the pedestrian street is a large Christmas tree, which is decorated with flowers and yellow ribbons of gifts, like fruit. There were still a few people stopping under the tree, apparently trying to make an appointment. Looking around, Li Su found the person he was looking for.

She was dressed in a simple winter dress, and her long black hair was casually draped over her shoulders. The dress has a thin shawl and a double row of buttons, a red and white Christmas color scheme, and shaggy white trim on the cuffs. She sat on a bench next to the Christmas tree, her same black eyes slowly scanning the surroundings, bright and focused.

With a light heart, Li Su suddenly felt that everything was not important, what about the son of the world? What about the unknown? Tonight is Christmas, and it's a beautiful day.

He waved his hand and ran to the Christmas tree, smiling all over his face.

The pupil of the mourners, end.
