Zhang Ye was also difficult all of a sudden, because these were all told to him by the system, but how to prove that he really didn't know, he thought about it, had a flash of inspiration, and said:

"Since all these magic are in the library for people to learn, then someone must be learning them, as long as you find someone who has learned the hidden black arts. ”

"Students who have learned hidden black magic? Well, I think it will work. Milan nodded, picked up the books on the floor, and examined them.

"[Blackwater Tide], [Vampire Thorn], [Stinging]...... Hmm, wait, this [Intelligence Aura] is also black magic?" Milan raised his head and looked at Zhang Ye incredulously.

"Yes, the intelligence aura can give the caster a clearer mind and keen perception, but this is actually a kind of magic that overdraws mental power!"

"Its special magic trajectory will cause the caster's mental power to weaken, and if used multiple times, it will cause vertigo, long-term use will cause mental malaise, and finally lead to mental breakdown. ”

Zhang Ye nodded and said.

"This ......" Milan was startled.

"What's wrong?" Zhang Ye wondered.

"Teacher, she...... I often use the Intelligence Aura. Suddenly, Lil said.

"What?"

Zhang Ye looked at Milan.

"Well, because the effect of the intelligence aura is very helpful to my research, I studied it a long time ago, and now I have fully mastered ......"

Milan said: "It's just that I didn't expect this magic to be black magic...... I can't feel the slightest dark breath, how can it be black magic? I can't figure it out......"

Milan covered her forehead, her brow furrowed slightly.

She had just applied an intellectual aura to herself several times when she was inspecting the flying boat, and now her mind began to feel dizzy, originally she thought that it was just that she had been too tired lately, and it would be good to take a rest, but she didn't expect it......

This is also the reason why when she was resting on the flying boat, she was disturbed by Zhang Ye, and her anger would be so terrifying when she got up, it turned out that her spirit had weakened to this point unconsciously!

There are even times when you can't control your emotions, which is definitely bad news for Milan.

"That's why it's called 'Hidden Dark Magic'......"

"Because it completely hides the dark aura and uses various methods to make it look like ordinary magic, but it can subtly cause the caster's body to collapse, or even cause even more damage!"

Zhang Ye said: "Sister Milan, don't use the intelligence aura in the future." ”

"I got it......" Milan was completely convinced, and the vertigo in her head made her very uncomfortable.

"Actually, it's not just me, many Radiant Dragon Clans and some students in the academy have also learned the Intelligence Aura, so it's troublesome......"

Milan suddenly thought, and her brow furrowed.

And she clearly remembered that this magic book with intellectual aura existed three years ago, which means that the person who set up the hidden dark magic started planning at least three years ago!

And she didn't even notice it, and even almost fell into the trap herself......

In her opinion, the upper echelons of the Zenith Library have infiltrated the black mage, and there is black magic hidden in the library, there is definitely a conspiracy, and it is a big conspiracy!

Who did this to you?

In fact, Milan already had a conjecture in her heart, but that conjecture made her feel a little frightened and powerless......

"Lil, gather all the clansmen at once, I have something to announce. Milan said to Lil.

"Okay teacher!" Liel also knew the seriousness of the matter, and immediately ran towards the Wizard Research Institute.

"Zhang Ye, thank you. Then Milan looked at Zhang Ye and said sincerely.

"Thanks, this is what I should do. Zhang Ye smiled, and then said:

"Sister Milan, can you take me to the higher levels of the library, I can find out all the hidden black magic!"

"I'm going to do it, but I can't do it openly. Milan nodded.

"Why...... Oh, I know!" Zhang Ye was stunned for a moment, and then showed a suddenly realized expression: "Sister Milan is afraid of startling the snake!"

"Funny, that's an apt word. Milan smiled and said:

"You're right, the people who can get involved in so many hidden dark arts in the Zenith Library are definitely not simple people, and I'm not sure if they still have a ...... left behind."

"I don't even know who they are, the enemy is dark and I am clear, so we can't get their attention......"

Saying this, Milan looked at Zhang Ye and was silent for a moment, and then asked, "Zhang Ye, can I trust you?"

"Of course you can!" Zhang Ye patted his chest and said, "Even if you don't believe me, you have to believe in Red Lotus." ”

Milan was stunned for a moment, a gentle smile on her face.

Yes, the people who are optimistic about Red Lotus can definitely be trusted.

"Okay, I will report this matter to the dean, don't worry, he and we are on the side, I will give you elevated permissions, and then you can freely enter the upper echelons of the library, this is related to the fate of the whole academy, please be sure to find out all the hidden black magic!"

"Leave it to me, I promise to complete the task!" Zhang Ye said rightly.

was entrusted with a heavy responsibility, and Zhang Ye suddenly felt that he had suddenly become taller.

The fate of the academy was in his hands, he was just a freshman before that, and he couldn't help but feel a little enthusiastic when he thought of this Zhang Ye.

......

......

After that, Milan summoned the clansmen and warned them not to use the wisdom aura again, and then Zhang Ye used the system to help Milan check all the flying boats.

Twelve of the hundreds of flying boats had their power furnaces artificially altered, and Milan, who learned of this, had an extremely gloomy face, obviously very angry.

Milan still had to discuss the matter of hiding the black magic with the dean, so Milan asked Zhang Ye to go back first.

"Huh?"

Suddenly, Milan's eyebrows lit up, and then she closed her eyes, and her consciousness was projected into a blank void space.

"Lian, what's wrong?" Milan asked puzzled, looking at the translucent red lotus projection in front of him.

If there is no important matter, Red Lotus will not use the Dragon Soul Soul to communicate.

As long as the contract between the two dragons is signed, the communication between the souls can be carried out, regardless of the distance, and there is no risk of being eavesdropped, but every time the dragon soul communicates, the initiator needs to consume a lot of mana.

This time the Dragon Soul Communication consumed one-fifth of Red Lotus's mana!

"Milan, I...... Need your help!"
