Xu Mo was frightened by Dean Messer's words, if it was really like what Dean Messer said, the elemental vortex he had inadvertently triggered just now was enough to bring him a catastrophe.

Just when Xu Mo was afraid, Dean Mercer then spoke:

"The elemental vortex is just a small problem, it's good if you pay attention to it, now you have a hidden danger, that's a big problem, if it is not solved well, it is likely to affect your future!"

Dean Mercer said this quite seriously, and this was the first time he showed a serious side in front of Xu Mo.

Xu Mo's heart sank, and he hurriedly asked, "Teacher, what are the hidden dangers on me?"

He went from a first-level mage to a third-level mage in just half a day, and he improved so quickly, if there were no hidden dangers, he himself would not believe it, but he didn't have enough vision to see anything wrong with him.

But Dean Mercer is different, he is the number one law god in the Holy Light Continent, Xu Mo believes that if it is him, he will definitely be able to see the hidden dangers hidden in his body.

As for whether the transparent crystal in his body would be discovered by Dean Mercer, Xu Mo was not worried at all, if Dean Mercer could really find the transparent crystal in his body, he would have found it in the last examination.

"There's something wrong with your magic core, according to common sense, a mage's magic core is completely composed of magic power, but your magic core has changed when it is condensed, from the original magic power to another more powerful force, and the condensed magic core is also unprecedented, so even I can't tell whether this magic core is good or bad, by the way, you use it to put a magic to see. ”

Saying that, Dean Maiser took out an extra fiery red magic book in his hand and handed it to Xu Mo: "Use your spiritual power to guide the magic power in your magic core into the Red Flame Book, and activate the strongest magic you can sense for me." ”

He knew that Xu Mo didn't know any magic, and it was strange to say that he had been crisscrossing the continent for so many years, and he was the first to see a third-level mage who couldn't cast any magic, and this strange mage was actually his disciple!!

He had already made up his mind that when the Demon Martial Arts Academy opened, he must give Xu Mo a retreat training, at least so that he could smoothly release third-level magic, otherwise let Xu Mo go out in the name of his apprentice, Xu Mo is not afraid of losing face, he is still afraid of losing face.

"The strongest magic?"

Xu Mo looked at Dean Mercer with a little hesitation, he was not worried that he would hurt Dean Mercer, he was mainly afraid that his magic would affect the books in his study.

As if seeing Xu Mo's concerns, Dean Mercer smiled: "Don't worry, with the teacher here, there will be no problems in your study, you have to learn to believe in the teacher, your teacher still has this ability!"

As if to prove his words, Dean Maiser stomped his foot, and then Xu Mo saw a layer of glass-like enchantment quickly spreading in all directions, and in the blink of an eye, the entire study room was enveloped in it.

The moment he saw this magic, Xu Mo was stunned, Dean Messer's magic reminded him of a character who had appeared in a movie he had seen on Earth, a terrifying character with strength!

"This is a mirror space, and even if you destroy the entire study here, it's fine, just let it go. ”

Seeing this, Xu Mo no longer hesitated, and concentrated his spiritual power to infiltrate the Book of Red Flames, and then he noticed that in his spiritual power, thousands of fire-based magic arrays appeared, and he could clearly feel the strength and weakness of those magic arrays

Controlling his mental power, Xu Mo began to search for the strongest magic he could release in these thousands of magic arrays.

Dean Mercer was not in a hurry about this, so he looked at Xu Mo quietly, and it took nearly five minutes for Xu Mo to select the strongest magic he could release among thousands of magic arrays.

Xu Mo carefully used his spiritual power to guide the pitch-black magic in the magic core into the Book of Red Flames.

The next moment, Dean Maiser, who was standing opposite Xu Mo, found that the original fiery red Red Flame Book had actually transformed into an extreme black under the penetration of Xu Mo's magic power!

"Roar!"

A black flame demon dragon burning with pitch-black magic flames appeared out of thin air, roaring and rushing towards Dean Mercer in front of Xu Mo.

At the moment when the black demon dragon appeared, the books in the entire study burned violently, and the pitch-black sea of fire instantly surrounded Xu Mo and Dean Maiser.

"Prison of the Void!"

With Dean Maiser's whispering, a transparent barrier appeared in the front and back, left and right, up and down, imprisoning the Black Flame Demon Dragon before it was about to devour Dean Maiser.

"Boom!"

The Black Flame Demon Dragon exploded violently, and the huge roar directly shook Xu Mo backwards, on the other hand, Dean Maiser had a breezy appearance, and even his expression was the same as before, as if everything that had just happened was what he expected.

"The magic I released with all my strength was actually blocked so easily, I really deserve to be a teacher!" Xu Mo exclaimed in his heart.

The fire dragon technique just now had already consumed all the mana accumulated in its body, and in the next period of time, he would not be able to release even the lowest level of fireball technique......

What he didn't know was that he didn't look at Dean Mercer's calm appearance at the moment, but Xu Mo's magic just now really gave him a beat.

At the moment when the Black Flame Demon Dragon appeared, he recognized that the prototype of the Black Flame Demon Dragon was a fourth-level fire magic fire dragon technique, and the fire dragon technique, which originally belonged to the magic of fire, actually turned into a mixed magic of darkness and fire attributes after Xu Mo's black magic power was released.

It was precisely because the fire dragon technique of the fire system mutated into the black flame demon dragon of the dark and fire type that its power would break through the original boundaries of the fire dragon technique and reach the terrifying sixth level.

"You recover your magic first, and then try it with this book of tempest, or unleash the strongest magic on me!"

Taking back the Red Flame Book in Xu Mo's hand, Dean Mercer took out a colorless prismatic crystal and a cyan magic book and handed them to Xu Mo.

If anyone saw the colorless prismatic crystal that Dean Maiser handed over to Xu Mo to restore his magic power, he would definitely be jealous and jealous to the point of madness.

That is, Dean Maiser has a lot of money, so he can be extravagant enough to give the Holy Demon Crystal used to break through the magic barrier to a small third-level mage as a magic recovery potion.

It is also miraculous to say that after leaving Xu Mo's hand, the Book of Red Flame instantly regained its original red color.

After receiving the Holy Demon Crystal, Xu Mo felt that in this small crystal, there was a huge amount of magic power hidden beyond his imagination, although the quality of this magic power could not be compared to the magic power he had condensed, but that huge amount was enough to change everything.
