When everyone is gathered to look at the red book with exquisite details that Kleint has, Liana and Lee Joon are very curious when they hear "Legendary Rank."
"Kleint, did you just say that book was Legendary Rank, or did I mishear being so far away?" Liana asked, curiously looking at the red book with exquisite details.
Lee Joon was also curious about the book but did not ask directly.
Kleint did not answer immediately but looked at Alice, waiting for her approval if he told them about the rank of the ancient alchemy book in his hands.
Alice, who understood Kleint's look, nodded without saying a word.
Seeing Alice's approval, Kleint looked at Lee Joon and Liana, who had bright eyes of curiosity, to know of the rank in his hands; letting out a sigh, he said:
"It's a legendary rank alchemy book."
"Legendary rank!" Lee Joon and Liana exclaimed simultaneously, their eyes wide as plates, surprised at what he had just heard.
And Kleint continued speaking.
"Besides, this one can only be used by an alchemist. That's why you can't look at the contents now."
"And do you know who the author of that book is?" I ask Lee Joon curiously.
"Willowbrook."
A confused expression appeared on Liana and Lee Joon's faces when they heard the strange name, which seemed to belong to an ancient era.
"And does it say what era it belongs to?"
"Hmm, according to the information it says. It belongs to the mystery era," Kleint replied with a neutral expression, looking at Alice, waiting for her reaction upon hearing the era's name since, as a regressor, she should know something about it.
She doesn't seem to know that era or control her expression. And if asked directly, she will be suspicious of me... thought Kleint when he saw that Alice did not change her expression.
Lee Joon repeated with a confused expression, "Mystery era?"
Kleint shrugged his shoulders while shaking his head; he didn't know anything about the mystery era either; he was waiting for Alice to say something, at least superficially, but seeing that she intended to speak, he sighed.
Alice, seeing the awkward silence in the place, said calmly, began to inspect the room again:
"Let's inspect the room again to see if we find another item."
The others started to inspect the room again, hoping to find another item.
A moment later, after searching the room and finding nothing, only the ancient alchemy book and the letter Liana read, nothing was essential or revealing.
"Well, let's continue."
They left the room and continued down the stone corridor lit by a crimson veil.
...
After walking down the long stone corridor, they encountered monsters like an Arachnid and a Darkbeast Parl.
When they saw the Darkbeast Parl, Kleint, Lee Joon, and Liana were horrified to see the appearance of this horrifying monster.
The appearance of the Darkbeast Parl was a complete aberration; its body was three meters long, almost hitting the ceiling of the place; it had multiple faces that had agonizing expressions as if they wanted to be released; it had numerous long hands and long claws used to keep the balance of its vast body. It also had a strange black fur that was completely rotten and gave off a black slime, which emitted a strong odor.
This sight made their bodies shudder with great force, but this time, Liana and Lee Joon did not freeze and managed to move.
While facing the Darkbeast Parl, Liana did not participate but paid attention as Kleint used magic. Although Kleint's magic was not very powerful due to his lack of mana, he used it effectively and hit at the perfect time, as if he were playing a turn-based game.
Liana witnessed this, and the confrontation was more prologue, unlike the previous one, and it was too much to react to; she felt like she was in some fantasy anime and was just a spectator watching all this from afar.
She tightened her grip on the ancient alchemy book while her brain worked at full speed, calculating many ways to use magic more efficiently.
"Kleint, throw a fireball at the center of the body, and Lee Joon, when the heart shows itself, try to pierce it."
Alice gave an indication, skillfully dodging the numerous hands of the Darkbeast Parl.
Kleint, wasting no time and using almost all the little mana he had created a fireball, but he did not throw it quickly but waited for the right moment to throw it and increase the chances of success.
He saw how Alice dodged many of the hands, leaving the center of her body vulnerable. He wasted no more time and launched the fireball.
The fireball flew quickly towards the vulnerable spot, which the Darkbeast Parl had left uncovered by attacking Alice.
Instinctively sensing the danger, the Darkbeast Parl tried to take cover, but it was too late to block the attack.
Boom!
The fireball impacted perfectly, and the multiple faces let out a cry of pain, perfectly showing their completely black and shriveled heart like rotten apples, which throbbed faintly and were connected to multiple blood vessels of the same color as the heart.
"Lee Joon, now!" shouted Alice, somersaulting like an acrobat and quickly appeared beside Kleint in seconds.
Lee Joon, surprised at the sudden shout but quickly recovered, quickly grabbed an arrow and sighed softly, calming his body.
With great precision and strength, he gently released the bowstring, and the arrow shot swiftly into the black, wrinkled heart of the Darkbeast Parl.
Stab!
The arrow pierced the Darkbeast Parl's heart cleanly, and its multiple faces began to let out a loud piercing scream with different voices of people, from elders to children, as it distorted and slowly drifted to the ground.
Once the Darkbeast Parl's body hit the ground, it turned into a black mace and, in seconds, became an utterly black puddle like oil.
A few seconds passed, and the puddle continued; Lee Joo and Liana sighed in relief as they regained the strength to continue walking down the stone corridor.
[Mana increased by 1]
This is interesting... So the mana increases without killing a monster, but it increases if you use it very often... But why didn't it increase when I was experienced when I got the class? Kleint shook his head to push his thoughts away for the moment.
Once Kleint gets out of this place, he plans to experiment; several things he has in his head to test if the mana increases as he thinks, and if it doesn't improve, well, he doesn't lose anything by trying, but now was not the time to start thinking about how to increase the mana. Still, he has to think about how to get out alive.
