"Alchemy is based on the understanding of the inner laws of matter: understanding, decomposing, reconstructing, alchemy must be carried out according to the law of "equivalent exchange": in order to obtain something, it needs to be exchanged for the same price, and if the price is not enough, it needs to be taken away by filling any part of oneself (part of the body, memory, etc.) as a price. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info" Regulus said to the crowd.

"This ・・・・・・・・ is not the same as the alchemy we know~" Asuna thought for a while and said, "The alchemy in my cognition is a profession that is good at refining metal products, and it has no combat power ・・・・・・・・・ itself."

"I'm talking about the alchemy of another world, and the alchemy of that world is even above magic! The strongest of them are the alchemists who come into contact with the truth, who come into contact with the truth at the cost of a part of themselves or the lives of others! Regulus said with a serious face.

"Truth!" When everyone heard this, they couldn't help but exclaim, the truth can be said to be the 'thing' that all magicians dream of!

"Hmmm! Just open that door to truth, and you can get the power of truth! Speaking of this, Regulus paused, and then said with a complicated expression, "Of course, since it is an equivalent exchange, of course, there is also the so-called 'toll'!" ”

"What's the toll?" Asuna asked with a puzzled expression, and everyone looked curious.

"The so-called 'tolls'! The price of sacrifice! You have to pay the price in order to gain the power of truth! Unless it is counteracted with the Philosopher's Stone, the truth will not let you touch it pricelessly! Regulus shook his head and said, "And there have been many examples of tragedy in the past, eternal life, which did not exist in the first place!" ”。

"The alchemists of that world have pursued 'eternity' all their lives, and contact with the truth is only the beginning of 'eternity', after refining the 'Philosopher's Stone', they will continue to eat away at the power of truth, and finally replace the truth as the only 'god'!" Regulus said with a gloomy face.

"Instead of 'God'? It's really a shame!! Uther said with a look of disgust.

"Well・・・・・・・・・ then, did those people succeed?" Asuna asked.

"Nope." Regulus shook his head, "I almost succeeded by an android, if it wasn't for his kid betraying him in the end, I guess he would have won a long time ago!" ”

"Will Arya become like those people?" Celica asked with some uneasiness.

"Huh? Hehe~ How is it possible! Every one of them who comes into contact with the truth has his own dream! Regulus smiled gently, "As far as I know, there is a boy in that world named Edward Elric who has become an extremely powerful alchemist since he was 12 years old! ”

"It's amazing・・・・・・・・・・"

"He and his brother Alphonse Elric were gifted alchemists, and they began the study of truth at an early age until the death of their mother・・・・・・・・"

"The death of their mother devastated the two of them, and they kept looking for the alchemy to resurrect their mother, and then ・・・・・・・・・"

"They found it?" Uther asked.

"Hmm!" Regulus nodded, "The human body is made - in alchemy, it is a taboo among taboos!" They collected all the 'attributes' that could make up the human body and opened the door to truth! ”

"Then did they really resurrect their mothers?" The curiosity of the crowd was gradually aroused.

"Huh! That kind of thing is their mother too? Regulus sneered.

"What do you mean by that?" Uther frowned when he heard this.

"Hehe~ The two of them didn't know that it would take a 'toll' to open the door of truth, but as a result, the younger brother was completely swallowed by the truth, and the elder brother lost an arm, and then refined the ・・・・・・・・"

"Their mother! Right? Luca said, clearly thinking too beautifully.

"Refined a 'alien' that is not a human at all! In desperation, the elder brother once again opened the door of truth and truth, and fixed his brother's soul in an armor at the cost of one leg・・・・・・・・"

"Utter tragedy~" Uther said with some sadness.

"Then Regulus, the 'Philosopher's Stone' you talked about earlier, what the hell is ・・・・・・・・・," Lia, who was silent on the side, spoke.

"Oh! Well, it's actually an amplifier that ignores the principle of "equivalent exchange" and can be refined into any matter of the spell. Regulus said disdainfully.

"Ignore the 'equivalent exchange'! That's not amazing! Sirika said.

"Awesome? Every Philosopher's Stone is refined from the lives of countless people! One of the most typical is Edward's father, Hohenheim! When he refined the first 'Philosopher's Stone', he sacrificed an entire nation! Regulus said angrily.

"One ・・・・・ a whole country !!" Everyone was shocked when they heard this, and even Woe showed a surprised expression.

"Of course, that price is proportional to the benefit, so Hohenheim becomes an immortal humanoid philosopher's stone, and there is little that can kill him unless the philosopher's stone in his body is completely depleted・・・・・・・"

"Isn't that more powerful than the Bloodline!" Arya said.

"Hehe~ Then now, do you still want to be an alchemist?" Regulus said, looking at Arya.

"Arya・・・・・・ forget it!" Celica persuaded.

"yes, yes! Even if you become a magician, it wouldn't be bad! Luca said.

"I ・・・・・・・" Arya opened her mouth, then said with a determined face, "I want to be an alchemist!" ”

"Colorful shopping!" Regulus smiled and snapped his fingers, and then the next moment a magic circle suddenly appeared on the ground in front of everyone, and a stone door engraved with the Kabbalah Tree of Life suddenly appeared in front of everyone.

"This is ・・・・・・・," Arya looked at the stone gate in front of her with a blank expression.

"The Gate of Truth ・・・・・・・" everyone was also surprised when they saw this.

"Push it away, and when you see the 'truth', chant your wishes, and it will give you the power of the truth!" A soft smile appeared on Regulus's face.

"But, 'tolls' ・・・・・・・," Arya's little hand stretched out to the door of truth suddenly shrank, and she turned to Regulus and said, "Didn't you say that you want tolls?" ”

"I've already given the 'toll'! Look at that! As he spoke, Regulus pointed to the side of the Gate of Truth.

"That's ・・・・・・・・" The crowd only now discovered that there was an incomparably ornate cross sword next to the door of truth!

"Durandal - the protagonist of the great French heroic poem "The Song of Roland", the holy sword of the Holy Knight Roland, the head of the twelve knights under Charlemagn the Great. A brilliant sword with three wonders that will not drop in the slightest even if the owner's magic is exhausted by its sharpness. Like the caliburn, it is forged with great magnificence and is a symbol of authority. Regulus spoke slowly of the splendor of the Noble Phantasm.

"With the glory of this precious Phantasm, it's enough to sustain you back and forth, Arya!" Regulus touched Arya's head, and then said, "Sa~ go and push open the door of power!" ”
