The invisible force field wall was completely annihilated by dissociation techniques, and the anti-magic rays were aimed at the crystal ball in Lucian's right hand, trying to penetrate it, building a small anti-magic field inside it, and cutting off its connection with the magic tower.

Lucien had been hit by the anti-magic ray anyway, and his own magic ability was limited, so he didn't try to use magic to counteract, his right hand stretched out, directly blocking the anti-magic ray, and at the same time, he finished reciting the spell that made people's eardrums tingle - this is not his own magic, forcibly interrupting it is just a little backlash damage, and now he is using the spiritual power of the five rings to manipulate the magic tower of the seven rings, temporarily suspending and changing the spell will make the surging energy fight back, and the soul will be seriously traumatized!

Thick silver-white lightning slashed down from the ceiling, instantly turning the entire room into a sea of thunder, and everything in the old witch's study was destroyed by electric light, except for the desk and floor engraved with the pattern of the magic tower.

Seven Rings Magic "Lightning Storm"!

Layers of hollowed-out light and shadow suddenly appeared around the old witch, and all the lightning that struck her disappeared silently.

Seven Rings Magic "Energy Immunity - Electricity"!

Immediately after, the yellow-brown sphere of the old witch's left eye shot out one after another, some seducing humans, some making people fall asleep, some directly causing harm, some frightening and sluggish, and some petrifying or dissociating, and the yellow demonic giant eye in the center was filled with a strong aura of death.

Seven Rings Magic "Finger of Death"!

After such a surging and furious attack, the old witch's transformed "left eye" dimmed. Temporarily loses caster ability.

In fact, none of the Eye Fiends would fight in this way, they would reasonably distribute the use of different eyes to ensure that they could cast spells continuously, but the old witch had completely ignored this, and seemed to have fallen into madness, or for some other reason.

Lucien dared to be careless in the face of such a terrifying attack, and stroked the crystal ball with his right hand, and with the spell issued from his mouth, the invisible "magic prison" fell out of thin air and trapped himself.

Rays of fear, sluggishness, seduction, sleep, and death hit the "magic prison". But you can only dye it with a halo of different colors. The dissociation technique of the dark green caused it to fall apart and quickly disappear.

A frenzied attack doesn't mean a perfect attack, and if the old witch had a sequential shot, the "magic prison" would either have been broken down in the first round of dissociation. Either trap Lucien himself. Make the battle initiative change hands!

After blocking this round of scalp-tingling attacks. Lucien suddenly noticed that the old witch had quickly and covertly glanced at several beautiful stone sculptures on his right.

"Those stone sculptures weren't destroyed in the lightning storm?" Lucien was shocked to discover the fact that they were made of. Or for the sake of the old witch who protects them better than the magic books?!

Without thinking too much, Lucien subconsciously recited the incantation, and a huge claw that seemed to be made of crystal ice suddenly emerged from the floor and grabbed at the stone sculptures of the beauties.

Seven Rings Magic "Sagimang's Crampons"!

The magic tower can produce limited magic effects, including those that have been used, there are only nine kinds, Lucien is worried that if the battle continues, the old witch's various magic spells will make him lose without suspense, so he did not hesitate to change the target of attack after finding out that there was something wrong with the beautiful stone sculpture.

At the same time, Lucien, who was worried that the old witch would take the opportunity to attack him, continued to chant the incantation without pause.

The old witch screamed angrily, and black gas erupted from her body, spreading in waves in all directions, and Adam, who had just recovered from the glass form and slowly crawled to the corner, immediately fell into a state of exhaustion and weakness.

The seven-ring magic "Wave of Exhaustion", the constant and powerful magic of the old witch's magic robe. Her own spells are still in the buffer of casting energy immunity.

Although he knew that he would lose the strength to speak after being hit by the wave of exhaustion, Lucien did not panic and calmly finished reciting the incantation, and a dark ray shot out of the wall and landed on the clearing in front of Lucian.

As soon as the anti-magic rays hit the ground, a small anti-magic field was created, and the waves of depletion subsided on their own as soon as they rushed here, and several beautiful statues pinched by the giant crampons erupted with the light of many protective spells, canceling out the crampons.

"Sure enough, there is a problem!"

"As soon as I entered the core of this magic tower, I felt a little weird, the old witch is a woman, and she is abnormally old because of the curse, why would she put a statue of a beautiful woman to find herself unhappy?!"

"The old witch's body and soul have decayed and aged to this extent, why hasn't she died for hundreds of years?!"

"This is the core of the magic tower, the most heavily defended place, and it's normal to hide the most critical and important things!"

Countless thoughts rushed to Lucian's mind, and the crystal ball floated into the air, taking on the color of ruby. A crimson light shot out from it, striking hard at the remaining statues of beautiful women.

The seven-ring magic "Ruby Reversal Ray" can remove the highest level of defense on the target!

The defensive magic on several beautiful statues had been consumed a lot in the lightning storm as early as possible, and it was partially offset by the "Crampon Cage" again, so after being hit by the ruby reversal ray, the light on one of the statues quickly dimmed, revealing a plaster-colored body.

"Ahh

Lucien understood that he had found the old witch's weakness, and took advantage of the momentum to pursue, and the spell sounded again, and thick and terrifying lightning filled the vicinity of the old witch.

Bang bang, a statue of a beautiful woman who had lost all her defenses was split into pieces by lightning, and a faint soul disappeared into the electric light.

The old witch seemed to have aged a lot, her back was so stiff that it was about to break, her right eye became more and more cloudy, and her reformed left eye suddenly dried up.

"Sure enough, it's something like a life-locking thing!"

The "lightning storm" continues, and Lucien quickly imposes a "magic prison" on himself. It's a spell that traps people. However, if you can perform the dissociation technique, it is an excellent defense option to avoid being killed by the old witch's outburst.

As the statues of beautiful women were shattered, the old witch lost her magical ability to stay in place, and became older and older, and when she reached the most pulver, she directly decayed and suppurated.

"Did you finally kill her?" Lucien thought. When facing the high-level magician, he had been tightening that string, fearing that the situation would be reversed by her endless powerful magic, but when he was close to victory, a sense of unreality suddenly emerged. Killed a high-level mage like that?

"What about her spell triggers, consumed in the underground ruins?"

"There seemed to be a problem with her choice of magic a few times. Otherwise, I'll be able to keep me under control before I find out that the statue is her weakness......"

One question after another rose in Lucian's heart, and Adam, who had lost his strength, let out a happy voice through the secondary psychic connection: "Man, you really have a trick, you really killed the old witch!

"Adam. Don't rejoice too soon. We'll have to go to the underground ruins. I hope to find a way out. Lucien saw that the old witch was slowly softening, and finally let go of the doubts in his heart.

At this time, a strange smile appeared on the old witch's face.

"Oops?"

Lucien was on alert. The entire magic tower shook violently, stone bricks fell one after another, and a cloud of dust flew away.

Lucian's head began to blur, and everything around him went dark.

............

The darkness receded, the light returned, and Lucien subconsciously turned over and sat up, but he was stunned to find that his hands and feet were imprisoned by something.

"It's good, your magic foundation is very good, the development of magic in the past few hundred years is really beyond imagination. The old witch's old laughter rang in Lucian's ears.

Lucien turned his head in astonishment, and saw that the old witch was still wearing a red magic robe, with her back bent, and her face wrinkled to walk back and forth, and she was lying in the familiar magic laboratory, as if she had just received "electric shock therapy".

"This?" the inexplicable change made Lucien subconsciously question.

The old witch smiled proudly, "The Six Rings Magic Dream Casting Technique, let me easily know your magic level and the current development of magic. ”

The previous escape was just a dream, no matter how good Lucian's psychological quality was, it was inevitable that he would be a little dazed, but this also explained many doubts, such as how he could unlock the forbidden demon collar for Lu, he still couldn't open the soul library, he couldn't summon Rhein, and there would be problems with how many magic choices he had for the old witch, and so on.

"Given your so-called 'arcane' level, I'll take you into the underground ruins. There's a maze inside that is very troublesome, I hope you can surprise me. The old witch seemed to have found a solution to the problem, and seemed to be quite happy.

Lucien quickly regained his composure and seized the opportunity to bargain: "Lady Eudullah, I think unlocking my forbidden collar will help me help you explore and navigate the labyrinth. ”

"No problem, I'll help you solve the maze before you go in. "As a powerful high-level magician, the old witch had no worries that Lucien would turn against her.

The old witch then led Lucien all the way to the bottom of the magic tower, and then down a winding staircase to an underground passage.

The entire passage is five or six meters high and seven or eight people wide, all covered with huge stone slabs, and the left and right walls are carved murals of ancient humans fighting underground monsters.

"This underground ruins are truly magnificent. Lucien sighed heartily.

The old witch did not speak, but walked to the end of the passage, where there were ten gates, each painted with a different mystical symbol.

"This is the labyrinth. The old witch pointed to the gray doorway in the middle.

The symbols on the gate were vaguely familiar to Lucian, as if they were different mathematical symbols, so he asked suspiciously, "Lady Eudulla, what is in the labyrinth?" ”

"There are no monsters, just puzzles...... "The old witch looked a little embarrassed, and then lifted Lucian's forbidden collar and imprisoning bracelet, urging him to enter.

Feeling the recovery of mental power, Lucien pushed open the gray door and slowly walked in, since there are no monsters, it should be a simple thinking labyrinth.

As soon as he entered, the door at the back closed silently, and Lucien, who had dark vision, found himself standing on an endless bridge, surrounded by an endless void.

"Nothing?"

Lucien thought to himself as he strolled forward, only taking two steps, and suddenly changed around him.

Stars condensed in the endless void, and these brilliant stars passed in front of Lucian's eyes one after another, and the light reflected words one by one.

"Please prove that any even number greater than 2 can be written as the sum of two prime numbers......"

"Huh?" Lucien watched the change in amazement, and the stars that followed directly became one math problem after another, all of which seemed to be the content of the "Jimidovich Mathematical Analysis Workbook" that he had only started practicing some time ago.

The mathematical symbols, numbers, equations, hypotheses, etc., surrounded Lucian, and soon his mind began to fog, and suddenly, the darkness shattered violently, and the light reappeared strangely.

Lucien opened his eyes, shook his heavy head blankly, and reflexively looked around, only to see Elvis, who should have died, sitting on the side.

He covered his mouth and nose, drops of blood fell, muffled his voice, and angrily accused:

"What's going on in your head?!" (To be continued......
