The Dean's Office Building of the Academy of Magic has two floors, and the old magician's office and rest area is on the second floor. The people of the School of Magic generally believe that the view and view of the second floor is better than that of the first floor, which is an important reason why the old magician lives on the second floor. The more down-to-earth layer is a mysterious place, and no one, including the students of the Academy of Magic, knows what this layer is for. Because there is only one corridor on the first floor, the walls on both sides of the corridor are closed, and there is not even a door. And it seems that there is not even a room on the first floor of the dean's office building, so many people speculate that there must be some secret hidden inside.

But what's the secret?

The answer was right in front of Felicia and Kelly, who followed Fama Quex to the end of the corridor on the first floor, where a wall stood.

The old magician seemed to ignore the existence of the wall, and kept moving forward, but his mouth was not idle, and he began to chant magic spells, and the earthy yellow lines appeared on the surface of the plain wall, and then the whole wall glowed yellow, and the originally hard rock on the wall began to wriggle and turn into tiny particles.

The particles automatically separated when they encountered the human body, and the old magic walked directly into it, and when his figure disappeared on the other side of the wall, the particles on the surface of the wall returned to their original state.

Felicia covered her mouth, stunned by the scene in front of her, but Kelly didn't show the slightest look of surprise, obviously she had already seen the change in front of her.

"What are you doing, let's go!"

Kelly nudged her behind Felicia, and the two of them walked into the wall together, and when the two appeared on the other side, the old magician's spell stopped, and the light on the wall behind them disappeared, reverting to a plain stone wall.

Behind the stone wall is a huge stone chamber, the stone chamber is divided into several rooms of different sizes, and the first thing the old magician does when he enters is to activate the lighting magic array to illuminate the entire stone chamber.

"Kelly, you're guarding here, I'll go over there and activate the magic array. ”

As soon as the old magician entered, he commanded, and after saying that, he walked to a separate room inside, but after a few steps he stopped again, turned back to look at Felicia, and admonished:

"Felicia, you're not familiar with this place, listen to Kelly, don't move. Got it?"

"Understood!"

Felicia nodded, then began to look at the entire stone chamber.

"So many magic crystals!"

When she saw the scene in the stone room, Felicia was surprised again, there was a stone platform in the middle of the stone room, and there were two magic circles on the stone platform, one of which Felicia quickly recognized the identity, this is a magic array that gathers demons, and stores magic elements for the magic crystals inlaid on it. The other magic array is completely different in terms of materials and runes, the entire magic array is composed of a huge bone, there is no obvious splicing gap between the bones, if this is really a beast bone, then this monster must be very terrifying before its death, and the most surprising thing for Felicia is that the surface of the beast bone material is inlaid with a lot of magic crystals, plus the crystals on the other magic array, the number has been so many that the magic crystals she has seen in her life add up to not so many, and the surface of these crystals is all glowing yellow, all of which are large earth-based magic crystals。

"What is this?"

Felicia suddenly noticed that there was something strange about the shape of the magic crystal set in the center, to be precise, it looked smooth and round, without the specific edges and corners of the crystal, and it was at least two or three times larger than the other magic crystals.

It wasn't a magic crystal.

"Say it, you may not believe it. This basement is stored in a giant earth guardian magic array, and the beast bones below it are a whole piece of turtle dragon beast carapace, which is inlaid with a total of thirty-six large magic crystals, and the most important thing is that the core of this magic array is a turtle dragon beast's magic core. Although the magic core has attenuation, it is relatively simple to drive the magic array, and the magic release speed is fast, and it has its unique advantages in the magic array. And these are only part of the magic circle, the real magic runes are in the teacher's room. All of this was done by the teacher with the assistance of several court archmages in five years. ”

Kelly pointed to the magic core in the center of the magic circle and gave Felicia a detailed introduction. Before Felicia had more questions, the old magician's somewhat desolate spell sound had already sounded in the next room, and Kelly also began to concentrate and calm down, cooperating with the old magician to chant the magic spell, the magic crystal in front of them lit up one after another, and the earth-based magic elements in the magic crystal were released, wandering along the lines on the magic array disk, and finally gathered on the central magic core, and the entire magic array suddenly shone brightly.

A bucket-thick yellow light stretched out from the core, and along the thickest magic rune, it was transported towards the magic circle in the other room. With a shock to the entire magic array, a yellow light curtain rose from the surface of the magic array, and then quickly expanded outwards until it completely disappeared. After a while, Kelly stopped chanting the incantation, and the energy on the magic runes was still flowing, but the speed had slowed down, and the light on the surface of the magic core was much weaker, but the energy in the magic crystal could continue to replenish it.

"Kelly, are you alright?"

Felicia asked, holding Kelly.

"I'm fine. The magic array has stabilized. ”

Kelly gently wiped the sweat from the corners of her forehead with her sleeve, it was a very expensive thing to cast a spell to mobilize such a huge amount of magic energy just now, but fortunately, the magic array was already fully operational, and there was no need to maintain it with magic spells all the time.

"What are we going to do now?"

"Wait! Wait for the enemy to arrive. But you don't have to be afraid, this magic array of the teacher can envelop half of the magic academy, and no one will be able to break through unless all the magic crystal energy here is exhausted. ”

Seeing that Felicia's face was not very good, Kelly thought she was frightened, so she comforted her. For the rest of the day, the magic array was quiet, and there was no sign of being attacked by the enemy. This calm lasted until the evening when it was broken, and the otherwise peaceful magic array suddenly vibrated violently. The flow of energy on the surface of the array disk began to accelerate, and the light flickered again. When it was serious, the light of the magic array flickered like a candle in the wind, and the old magician had to rely on magic spells to keep the entire magic array stable. Soon the energy of some magic crystals was depleted, and at this time, Kelly would take a few crystals from the magic storage array next to them and replenish them.

"The teacher said that once the energy in the magic crystal is exhausted, the crystal must be replaced immediately, otherwise it is easy to give the opponent a chance to take advantage of it. ”

Changing the crystals, Kelly explained.

"Look at the time, it should be almost dawn and we will win in no time. ”

I don't know how long it took, but the attack outside finally stopped, and the old magician, who had been in the room all night, finally came out, his voice hoarse, his expression extremely tired, only a pair of eyes still bright.

"Kelly, I'll go out for a while, you're on guard here, as long as you make sure that the magic energy in the magic core is sufficient, the enemy is helpless. Felicia, you help Kelly. ”

The old magician finished speaking, recited the magic incantation, and walked out of the stone wall again. Shortly after he left, Kelly heard a strange sound coming from outside, still clear even through the heavy stone walls.

"Bang!"

Followed by a dull sound, the entire magic array shook violently, and the light of the turtle dragon beast demon core on the array disk dimmed suddenly, as if the magic elements stored in it were emptied in an instant.

"Not good!"

Kelly was shocked, if the magic elements in the Turtle Dragon Beast's core could not be replenished in time, even a brief pause might give the enemy a chance to take advantage of it. She immediately put all her mental power on the magic array, and began to cast spells with all her strength to speed up the release of the magic elements in the magic crystal to make up for the loss in the magic core. But at this time, the magic array was already running at full speed, and the elements in the magic core were rapidly withdrawn, and the elements in the magic crystal were not enough.

"Felicia, hand me the magic crystal over there. ”

Kelly shouted at Felicia.

"Good!"

Felicia agreed, and she walked to the side of the magic storage circle, but did not move.

"Felicia, what are you doing? Give me the magic crystal. ”

Kelly's voice was anxious, but Felicia remained unresponsive.

"Kelly, I'm sorry. Andrei is just outside, I can't help you. ”

Felicia turned her head suddenly, her face covered with tears.

"You..."

Kelly finally understood what was happening, she stopped casting spells and rushed up to push Felicia away, removed the magic crystal from the Gathering Circle, and replaced it for the Earth Guardian Circle. By the time she completed the replacement, the energy in the Turtle Drakemon's magic core had just been exhausted, and she hurriedly recast the spell to drive the magic array to replenish the magic elements of the Turtle Drakemon's magic core.

The Turtle Dragonmon's magic core lit up again, and the magic array returned to normal.

"Do you know what you've done?"

Kelly pointed at Felicia, who was crying on the ground, and retorted. She understood that there was a moment when the Earth Guardian Magic Array had lost its protective effect because it had not replenished its magical energy in time. She only hoped for now that the enemy hadn't been able to grasp the fleeting moment.
