It seemed like a long time had passed, and it seemed like it was just an instant, and the crystal book had completely transformed into a huge ball of brilliant four-colored light.

In the four-colored light that continued to shine, Moriarty actually felt the strong aura of the four magical elements. The red fire element, the blue water element, the yellow-green earth element, the white wind element, and the four-color light sphere seemed to be the condensation of the four elemental planes, and Moriarty's soul became the perfect container for this condensed body.

Although he was amazed by the strange changes in the crystal book in his soul, Moriarty did not have any way to intervene or control it.

"Could it be that there's something wrong with the 'Hydrotherapy' scroll? No, I've checked before, and this 'Hydrotherapy' is the same as the previous 'Mud Steps', and it's a standard spell learning scroll. But why would the Crystal Book be..."Looking inwardly at the brighter and brighter four-colored ball of light in his soul, Moriarty thought quickly, "Just adding a water-based spell scroll is... Wait a minute... water system..."

Suddenly, an incredible thought popped into Moriarty's mind.

"The first attributeless 'Magic Arrow', the second, the wind-based spell 'Wind Breath', then the fire-based 'Fire Magic Defense', then the earth-based 'Mud Foot', and finally, the water-based spell 'Hydrotherapy'. In this way, the crystal book already has one of the four series of spells! Could this be the reason for the change in the Crystal Book? ”

And just as this bold assumption resounded in Moriarty's heart, the shining ball of light suddenly changed again. For some reason, the four-colored brilliance began to slowly mix, as if the water of the four lakes had been removed from the middle dam and naturally blended and merged, and could no longer be separated.

With the continuous fusion of the four rays of light, the color of the entire light sphere gradually becomes unified, deep and pure.

Red, blue, yellow-green, and white, representing the brilliance of the four magical elements, began to envelop the ball one by one, as if it had turned it into a neon sign that was constantly changing colors. Then, the ball of light flickered faster and faster, and the light became more and more intense, until at last even Moriarty's soul was overwhelmed by the incomparable brilliance. In the dark, Moriarty only felt that he had become the stage of the wrestling of the four elements, and the ball of light was the battlefield where the elements clashed fiercely and wanted to be monopolized.

"Smack!"

Eventually, in a distant cracking sound that only Moriarty could hear, a huge ball of light that had expanded to almost engulf his soul suddenly burst open.

Darkness replaced the brilliance of Fang Cai in an instant.

And when Moriarty tried to stabilize his mind and look inward, he saw only a crystal book with a rich flame glowing floating in the depths of his soul. Accompanied by a flaming aura that continued to loom like an epiphany, Moriarty's soul was also surrounded by a faint red aura.

Then, before Moriarty could react, the crystal book suddenly unfolded automatically, and then from the fiery red pages erupted an incomparably dazzling red aura.

The aura instantly pierced through Moriarty's soul, forming a slender flame of bright gold in the void. And at this moment, the layer of red aura that originally surrounded his soul quickly contracted and gathered as if it had been summoned at once, converging towards the golden flames, and then converging into a red ball of light like a silk cocoon, wrapping the golden flames in the center.

Soon, the newborn ball of red gold light formed and steady, and quietly hovered above Moriarty's soul, slowly casting a little flame aura to envelop the entire soul. …,

It was only then that the opened crystal book slowly closed again, and at the same time returned to its original transparent and clear appearance.

"It's... Could it be..."

Stunned as he watched the series of great changes that took place in his soul one after another, Moriarty was inexplicably surprised. From the expansion and rupture of the four-colored ball of light, to the unfolding of the Flame Crystal Book, to the aggregation of the red aura, and the birth of the bright golden flame, Moriarty could only wait as a helpless bystander, silent and anxious. It wasn't until the sudden appearance of the red ball of light that Moriarty finally got out of this chaotic and incredible situation, and vaguely recognized the true face of the red ball of light, even though the possible answer was so magical that even Moriarty himself could not believe it.

Quickly exiting his inner gaze, Moriarty stood up from his chair and opened the door to walk out.

"Moti, are you going out? Finished talking to Dad? Outside the door, Haiyana happened to come from the other end of the corridor, and when she saw Moriarty's strange face, she immediately stepped forward and asked.

"Yes, I'm going to the library once." Moriarty struggled to keep his mind at ease.

Fortunately, the changes in his soul did not affect his external condition, and after taking a deep breath, Moriarty showed a smile: "Uncle has given me a good idea, and then I want to find a place to think about it." ”

"Yes, okay." Looking into Moriarty's eyes, the girl instinctively noticed that the other party's expressions and movements were still a little strange, but she didn't delve too much into it: "Is there anything you need my help with?" ”

"No, I'll just go myself." Moriarty shook his head: "Also, I'll probably be back in the evening." ”

"Okay." Haiyuna nodded: "However, pay attention to your wounds, after all, they are not healed yet." ”

"Yes, I will." After saying that, Morati smiled again and strode in the direction of the teleportation array.

Hayuna continued to watch her lover's back until it disappeared completely, then turned and walked into the workshop.

Leaving the Mage's Tower, Moriarty made his way through the paths and lawns and into the Hockenheim Library.

In the morning library, there were not many people. Because most of the mages are notoriously night owls, or simply "jet lag breakers" who don't know what day and night are, Moriarty never saw anyone else along the way.

The caretaker on duty in the library today is still Master Tiger. Moriarty walked quickly up to him and saluted, "Good morning, Master Tiger. ”

"Hello, Moriarty Apprentice." Mage Tiger glanced at the Chief Apprentice Medal on Moriarty's chest, then nodded his chin and replied, "Is there anything wrong with you?" ”

"Yes, I'd like to borrow two books: 'The Mage Class' and 'The Elemental Realm, The Inner World of Magic.'" Moriarty said.

The names of these two books, Moriarty, had been seen in a treatise on mages and had always been in his heart.

"The Mage Class and The Elemental Realm, The Inner World of Magic?" Hearing Moriarty's words, Mage Tiger looked at the other party in surprise: "Are you sure, apprentice?" ”

"Yes." Naturally, Moriarty knew what the other party was wondering about, as both of these books were purely conceptual and theoretical, and did not bring any other substantial power or knowledge other than to provide some assistance in reading them similar to the explanation of the term.

"Okay." Seeing that Moriarty insisted without hesitation, Master Tiger lowered his head and looked at the list of contents, and then said, "The Theory of the Mage Class, the borrowing fee is ten gold coins; "Elemental Realm, the Inner World of Magic", because it is already a book with the permission of a first-class mage, the borrowing fee is fifty gold coins. ”…,

"Excuse me, can I borrow these two books?" At this time, Moriarty asked again.

"On loan?" Tiger instinctively wanted to refuse, but suddenly remembered the medal on Moriarty's chest, and after thinking about it, nodded: "Chief apprentice, you have this right." However, it should be noted that the cost of borrowing books will increase by 50% on the basis of what was just now. At the same time, if the book is damaged during the borrowing process, the borrower is required to pay the full amount of the loss. ”

"Yes, I see, thanks for the tip."

Then, after paying the borrowing fee of ninety gold coins and registering, Moriarty lent out "The Mage Class" and "The Elemental Realm, the Inner World of Magic".

Placing the two books in the sleeve pockets of his robes, Moriarty did not return to the Mage's Tower, but went straight out of Hockenheim to Fountain Square.

"Carriage!" Stopping a cab, Moriarty jumped on it: "Go out of town." ”

"Yes, Master Mage." The coachman glanced at Moriarty's mage's apprentice robe in awe, flicked his whip, and drove the carriage in the direction of the outside of Aquamarine.

After about an hour and a half, the wheels of the carriage slowly stopped. By this time, Moriarty had already arrived in the Roaring Gorge in the southwest outside of Aquamarine.

"You drive the carriage away for a walk, and pick me up in five hours." After throwing the coachman a bounty of gold, Moriarty gave him a command, and walked alone into the ravine.

"Yes, sir." Excitedly taking the gold coin, the coachman respectfully agreed, and drove away.

Roaring Canyon was once a well-known area for magical crystals.

Legend has it that in the tenth year after the establishment of Azurite City, the then lord of the city, the "Lady of the Deep Sea", stumbled upon a hidden vein of magic crystals here. After trial excavation, a batch of high-quality magic crystals was quickly mined, thus confirming that there is a large rich ore deposit here. Since then, this magic crystal vein has become the most important economic lifeline for Aquamarine City and the surrounding area. Even, in order to compete for this vein, Blue Crystal City and other armed forces have fought three bloody wars of great scale. However, the final winner was always on the side of Blue Crystal City.

In the following hundreds of years, under the firm control of Blue Crystal City, this mineral deposit produced a steady stream of high-quality magic crystals, and became the biggest support for the continuous expansion and development of Blue Crystal City.

But like so many other famous deposits throughout history, the Mana Crystal Vein has finally reached the end of its resource after a long period of excavation. About eighty years ago, the Mana Crystal was finally mined. After confirming that there were no more valuable minerals left, the official forces of Aquamarine City withdrew from here, leaving behind a large, artificial valley full of craggy caves. Every winter, when the frigid winds from the southern ice fields blow through the area, they wander back and forth between the valleys and countless caves, making a sound like the roar of a giant beast. This is where the name Roaring Valley comes from.
