The journey of dragon transformation starting from Demon Slayer

"I found my original dream...and looked back a little bit at my past self..."

There was a hint of exhaustion in Lefiya's words, but also a hint of freedom.

Having lost something important, she committed the same mistake as Luke.

Now she seemed to have relaxed everything, the "anxiety" in her body had dissipated, and she could feel that the things settled in her heart were gradually disappearing.

Of course, this doesn't mean that Phil Weiss has been completely forgotten from the bottom of her heart. But she changed back, back to the timid, crybaby, but usually cheerful and lovable Lefiya Viridis.

She will never forget that pain, and she has now experienced growth.

Thinking of this, the girl raised her head and looked at the young man sitting opposite, and found that he was staring at her with eyes filled with stars.

After realizing that he was secretly looking at each other, a reassuring smile appeared on his face.

"Then let's talk about Fairways Sharia... I guess you can't wait any longer, right?" Tazmi stood up from the sofa. Seeing Tazmi getting up, Lefiya also She was about to get up, but Tazmi said she could sit down first while he went to get a book.

He walked to the bookshelf nearby and took down a thick book wrapped in red cover that recorded the knowledge of "time" and "space", as well as "world lines" and "parallel worlds".

"You should take a look at this first... Before you do that, it is necessary to understand this first..."

Placing the book in front of Lefiya, Tazmi sat down on the sofa.

It actually contains more than just that knowledge, it also contains some exploration of history and some miscellaneous records.

This is written by him himself, his own understanding of this knowledge, and of course it also records the description and research of these terms by countless anthropologists at DXD.

It's okay to say that it was just a random note. Anyway, it was just a carrier for recording knowledge and a product for his research and reference. It was not that precious.

"that matter?"

Hearing what he said, the girl first glanced at Tazmi's serious eyes in confusion, then suddenly thought of "Hayate" and her companions, and then there was a clear understanding in her eyes.

Thinking of what would happen next, the girl's heart couldn't help but beat rapidly.

With excitement, Lefia lowered her head and looked at the huge book with a red cover.

First of all, the huge word "World" comes into view. Surrounding the font is a round sphere like the sun, with many dotted and solid lines of unknown meaning carved on it, as well as various patterns and animals.

The book cover is wrapped in unknown animal skin, which feels good to the touch. The corners are reinforced with special golden metal, and there are gear-shaped bumps on it as embellishments, making it look full of mystery.

Although it looks like a brand new book, the size of the book still gives it a heavy feeling.

Lefia thought so, then reached out and opened the first page of the book, and Tazmi's voice followed.

“The structure of ‘The World’ is very strange.”

"Different from the concept of a planet where various elements come together, the world itself represents a concept given by human intelligence. It exudes the wonderful unknown that attracts people's imagination and cannot help but want to pursue..."

The beginning of the book describes Tazmi's understanding of the world. It is not an annotation of the concept of the planet, but a more vague and hazy statement.

What follows is normal, with descriptions of the world.

What is the world? What is the world made of?

At a large scale, every planet or an entire universe can be regarded as a world. At a small scale, even a continent, a plane, or a small story can be regarded as a world.

The meaning of the world is forcibly given by people. Its concept represents the exploration and study of its essence by intelligent life, and is full of people's cognition and discovery of it.

In this way, people use the various nouns they have learned to give them precise meanings without authorization.

"Universe", "Star", "Galaxy", "Time", "Space", "Parallel World"...

There were many nouns written in the book, and Lefia could tell that the descriptions at the front of the book were only rough introductions. Although she could understand some of the vocabulary, there were some places that she still couldn't quite understand.

Since she is an adventurer and is only fifteen years old, she still has a lot of room for learning and improvement.

"Please read the 'Parallel World' first... Please turn to the next seventeen pages from this page..."

Tatsumi's voice was like a gentle whisper before falling asleep at night. Hearing him say that, Lefiya made corresponding movements with her hands.

"As an elf, you must know that there are many trees growing in a forest. And the patterns on the leaves of the trees will never be the same..."

Hearing Tatsumi say this, Lefiya's thoughts went back to her childhood.

When she was young, she did like collecting beautiful leaves, and of course she was curious about the patterns on the leaves.

It is indeed as Tatsumi said, it is impossible for leaves to have exactly the same patterns, even the leaves of the Great Sacred Tree are like this.

"It's not just leaves, it's also snowflakes in winter, it's also people, it's also the world..."

"The world is diverse, just as no two leaves have the same pattern. The world itself is also colorful..."

Lefiya's ethereal blue eyes looked intently at the knowledge in the book. She digested the words in the book word by word as she read through them.

Tatsumi's words are easy to understand, which means that the world she lives in is not the only one.

"Due to limitations in this world, it is impossible for two people to be exactly the same."

"Even if we relax the conditions a little, it's still difficult to find a person with the same name, personality, and gender..."

"What do you think this is limited to?"

Tatsumi asked the question out of the blue. Lefiya thought about it for a moment, then read a book for a while and quickly gave the answer.

"About...amount?"

She tilted her head cutely and looked at the boy. Tatsumi smiled and gave him a look of approval.

“Yes, it’s the quantity.”

"Only when there is a huge number, with the accumulation of numbers, can similar individuals appear..."

“But it’s just similar.”

"After all, it is impossible for people with similar experiences, names and genders to appear in the same period of history... unless she has the magic of clones..."

He paused at this point, then met the elf's gaze and said with a smile.

"However, the 'Parallel World' is an exception..."

After hearing what Tatsumi said, Lefiya looked down at the books spread out on the table.

"Parallel world" or "parallel universe", the records above describe in detail the information and inferences about this knowledge.

There is a sentence above that summarizes it like this.

A parallel universe (world) refers to another universe that is separated from a certain universe and exists in parallel with the original universe, which is both similar and different.

In these universes, there are also universes that were born under the same conditions as our universe, and there may be planets that are the same as the planets that humans live in, or that have the same history, and there may be people that are exactly the same as humans.

At the same time, in these different universes, the development of things will have different results.

For example, a species that has become extinct in our universe may be evolving and reproducing in another universe. It is also possible that a person who has died may still be alive in another world.

This theory itself represents the concept of "countless worlds" and contains infinite possibilities.

The knowledge in this book is different from the knowledge in the "Netherworld". Tatsumi was not in a hurry to speak, giving Lefiya plenty of time to think and read.

At this moment, the sunlight from outside shone through the huge glass, and the flame in the stove made a crackling sound.

Then about twenty minutes passed.

"Next, please turn to page 40. We need to understand the 'timeline theory' first, but you must first understand what the 'past', 'present' and 'future' are..."

"..."

--------

Time passed quickly, and after more than an hour, Lefiya finally finished reading the part that Tatsumi asked her to read, and learned a lot of knowledge that was completely different from what the school taught.

At this moment, she suddenly felt that her curiosity for knowledge seemed to have returned to her student days, and she had an urge to take the book back and study it carefully.

"I believe you have also noticed that Hayate's companion, the former leader of the Astraea Family, Alyse Raphel, and the others suddenly resurrected..."

"Their records are indeed as recorded by the guild. They died in the dungeon..."

"This is a fact and history..."

Upon hearing Tatsumi admit that Arise and the others were indeed dead, Lefiya's eyes widened in shock.

Seeing Lefiya's surprised look, Tatsumi curled the corners of his mouth and smiled.

They in this timeline were indeed dead, and all he did was to use the people in another timeline to cast magic to replace them in this timeline, thereby interfering with the "past" in disguise.

By doing this, there won't be any major problems whether it's a parallel world in another timeline or the timeline they originally are in.

As long as they are rescued at the last second before death and their deaths are disguised, history will proceed as usual.

Ryu would still witness the death of his companions and then go crazy to seek revenge on the "Dark Faction", and the world would not collapse beyond recognition because of his actions.

That is to say, there are major changes in the parallel world, but this is actually a branch of development towards the "future" and is not actually related to him that much.

What he needs to do is to try his best to preserve their bodies and souls after completing everything.

Seeing that the girl still had a confused expression, Tatsumi knew at a glance that she didn't really understand how Alisee and the others were resurrected.

"Okay, let me tell you how I did it..."

"..."

He sat down on the sofa and explained it carefully to the girl. Lefiya listened attentively.

As he explained, the expression on Lefiya's face changed from surprise to nervousness.

Her eyes were shining brightly, and her cute little mouth was open the whole time, with no sign of wanting to close it.

Well, although the season is not right, if possible, I really want to let her eat a cold ice cream.

He quickly explained the whole story, and Lefiya, who heard it all, was shocked and couldn't recover for a long time.

"Okay, so awesome..."

“Is this kind of thing really possible?”

Lefiya muttered in disbelief.

Just now, she was halfway through listening when she recalled the information about the white-haired woman lying on the recliner with her eyes closed when she first entered the room.

Chapter 671 "Girl's Departure"

"Silent Alfia", a Level 7 witch and a member of the "Hera Familia".

The woman lying on the couch was the descendant of the hero who tortured the Loki Familia to death seven years ago and gave them a trial.

She learned about the trials that Alfia and the others gave the Orario adventurers from the literature. However, this was the first time she had truly seen the true appearance of the hero.

Alfia is really beautiful, and she deserves to be called a witch.

However, as the story progressed, Lefiya began to slowly become addicted to it, turning around and forgetting about the "Silent Witch".

There is no way, who made the story unfold from the perspective of "Blast".

As one of the adventurers who also guides students in the "School District" and a fellow elf, of course she also has normal communication with "Liu Liang".

She also knows a lot about the other person's past.

It was the "wind of justice" that ended the city's dark period. Even though she was later wanted by the guild, the contribution she and her family made to Orario is still worth remembering by everyone.

Moreover, during the "Dark Period", one of the partners of the "Loki Familia" was the "Asteria Familia".

As a member of "Loki", she should also understand the growth history of her family.

There is also the "Resurrection of Justice" that has been spreading more and more in Orario recently. As a major participant in the "Man-made Maze Incident" and someone who lost something important, she will of course want to seize everything. A life-saving straw to grasp at.

Hayate reached Lv.4 five years ago, and has not updated his ability values ​​since then. His strength and skills are called the peak of Lv.4. Not only is she good at high-speed melee combat, but as an elf, she is also good at using magic.

Then not long ago, she suddenly became Level 6. With her successive breakthroughs and continuous upgrades, she became a big star in Labyrinth City.

Although it is information about a registered new adventurer, everyone said it.

"Hayate is resurrected!" Woohoo! I have been a fan of these righteous girls for a long time! 』

"Don't talk nonsense, Hayate has died long ago, and now you are a new adventurer! Elf Lady Astraea and her sisters! 』

"That's ridiculous. How can there be any Level 6 new adventurer..."

"I'm more curious about what kind of "unknown" happened that brought them together again today..."

"So what exactly is going on!" Wasn’t he already dead? What kind of lies are the officials telling? 』
