Around eight o'clock in the morning.

A short old man in a plain robe walked to the door with a wooden cane, and when the snow wolf mercenary saw an unknown person appearing, he immediately stopped him and said, "Little old man, stop! Guests are not welcome here, hurry up!"

The mercenary just wanted to push the old man away, but a force came out of the earth, and his feet seemed to be sucked in, and he couldn't move.

Warlock?

The two were stunned.

"Offended, I'm a Warlock of the Academy Alliance. Gu Boyun straightened his glasses, looked around the mercenary, and looked at the ordinary room, "Does Master Mu live here?"

"Master Mu?"

What's the situation?

Now a sorcerer can be called a master?

This guy's mana is not weak, I'm afraid he is not a simple person.

This thin and small old man is Gu Boyun, a famous great magician in Baicheng, an authoritative figure in the magic world, and the only one who can compare with him in the entire Baicheng is Weng Lianhai of the Warlock Guild.

Of course, the mercenaries are not recognized.

"Okay, wait!"

One of the mercenaries went in to report.

Mu Yun was studying a formula that she had never seen before in the laboratory, Mu Ying'er didn't like to do research, so she sneaked out early in the morning to play, and only the studious Qin Yue stayed by her side to help.

"There's an old man who calls himself the Academy Alliance to visit!"

Mu Yun was slightly surprised when he heard this.

Faculty Alliance?

Zhao Pu found out about this place?

Mu Yun didn't solve the formula, and said casually: "I'm busy, I can't leave." Take it to the living room to make a cup of tea and entertain it!"

The mercenary relayed it.

Gu Boyun had no opinion.

The famous warlocks in each city, Gu Boyun has a basic understanding. This Mu Ying'er has never heard of it, it must be a hermit master. This kind of master is indifferent to fame and fortune, and his temperament is mostly eccentric, and he has his own needs from others, so it's better to be polite.

The mercenary followed Mu Yun's request and made a cup of tea for Gu Boyun.

Let Gu Boyun stay in the living room, and the mercenary left.

Gu Boyun was itchy and couldn't bear to pace in the living room.

Suddenly, he found a half-hidden room, as if ...... It is a study.

Gu Boyun hesitated, but couldn't help but walk in.

I saw the bookshelf and talked about a few books "Basic Pharmacy", "Basic Array Method", and "Basic Rune Analysis...... These are all very basic books, it is really strange that a master of magic has a deep knowledge of magic, why is the study room a basic book for each apprentice?

The desk is lined with ink, pens, scratch paper, and books.

"Notes?"

The notes on the desk, the handwriting is round, delicate and beautiful, probably from the hand of a woman. Mu Ying'er...... This name is also a woman, Gu Boyun knows that it is a shameful thing to steal other people's spell notes.

"This study is so ordinary, and there are no protective measures, and the things that are randomly placed on the table must not be precious materials!"

Gu Boyun found a good reason and sat down and opened his notes.

"Dark Array!"

Gu Boyun glanced at it, and the blue tendons on his forehead were highlighted!

Spell Array!

Spell templates!

Gu Boyun couldn't close his mouth in surprise, Master Mu Ying'er not only discovered the law of dark energy, but also took the lead in researching dark spells?

No way!

You can't buy this kind of material for 100,000 gold coins!

I can't watch!

Gu Boyun hurriedly closed the notebook, and his heart was up and down, as uncomfortable as a cat scratching.

Because, he wants to see it so much!

Is the spell template valid?

Is the spell structure really perfect?

If this is really a dark spell, even if it is an apprentice spell, the meaning is huge, at least it means that the dark spell is real. Gu Boyun has studied demons for more than ten years, and is particularly interested in demon power, and is determined that human beings have a way to control demon power, just as the human race controls the power of the five elements and controls the power of life.

This notion was ridiculed by many.

A spell!

All it takes is a simple dark spell that will immediately turn into ironclad evidence and silence all doubts!

See?

Don't look?

I struggled fiercely!

Moral torture!

The temptation of knowledge!

Gu Boyun was tormented.

A respected old warlock, full of peach and plums, and a very high moral level, he really can't do this kind of peeping at the research results, let alone disdain to do it.

But.

An unguarded huge treasure was in front of him, as long as Gu Boyun was willing, he would definitely be able to take things away, and no one would want to stop it. In this treasure, there is the knowledge that Gu Boyun has studied for half his life and is most eager to get!

"I only watch, I don't spread it...... The copyright of spells and knowledge is still Master Mu's!"

"No, no!"

"This is self-deception!"

After more than ten minutes of struggle, Gu Boyun finally made a difficult decision...... Abandon!

As a scholar of high morals.

As a professor who teaches and educates.

This kind of thing is definitely not what he should do, without Master Mu's personal consent, even if it is placed in front of him, he will not look at a word.

Gu Boyun sighed.

When I looked up, I was stunned.

Because there was a person standing in the study, not very old, petite and cute, with white and tender skin, a good figure, with a refreshing ponytail, wearing a white sable bear coat, a pair of innocent eyes blinking, holding half a string of sugar gourds in his hand, and the corners of his mouth were red rock sugar.

Gu Boyun was a thief, and hurriedly got up and made a silent gesture.

Mu Ying'er took a bite of the sugar gourd and asked vaguely: "Grandpa, who are you? Why are you in the study!"

"Don't get me wrong! I didn't see anything!"

Mu Ying'er showed an inexplicable expression, walked in and said, "Grandpa, what are you nervous about? There are no secrets here!"

"There are no secrets, you say there are no secrets!" Gu Boyun was old, his heart was almost stimulated, he could feel that there was a little energy fluctuation on Mu Ying'er's body, presumably an apprentice, and immediately asked, "Are you a student of Master Mu?"

Master Mu?

That's a good name!

It's quite suitable for the young master!

"That's right, Master Mu is my spell teacher!" Mu Ying'er puffed up her chest proudly and said proudly: "He is amazing, my knowledge and spells are all learned from him!"

The girl is about 15 years old and has 8 rings of upper and lower mana, no wonder Master Mu Yinger will take a fancy to her. This kind of good seedling, Gu Boyun will not let it go when he sees it.

"You're too hasty...... How can these precious materials be placed here casually?" Gu Boyun folded the notebook together and sent it to Mu Ying'er, "Quick, put it away!

Ying'er was very puzzled: "Master Mu doesn't care about this knowledge at all, if the old man is interested, you can just watch it! I guarantee that Master Mu will not blame you!"

"When...... Really?" Gu Boyun's heart was about to pop out, "Can you guarantee it!"

Mu Ying'er took another bite of the sugar gourd, patted her chest and promised, "Don't worry!

"That'...... Then I'll really see it!"

"Grandpa, you're so long-winded!"

Gu Boyun was taught a lesson by a little girl for the first time in his life, but he was not dissatisfied, but overjoyed. He found a suitable reason, and Master Mu Ying'er's students agreed to watch it themselves, so it shouldn't be considered voyeurism. Gu Boyun was afraid of missing the opportunity, so he immediately flipped through the notes and found the first spell template.

"This template...... Why does it look so strange!"

"Hehe, I don't understand, let me teach you, this is a level 0 dark spell [Corrosive Finger], the principle of the spell is to tap the corrosive potential in dark energy. While eating the sugar gourd, Mu Ying'er told Gu Boyun about the spell principle that Mu Yun taught her, and said, "The arrangement and principle of the spell runes are like this......

An apprentice is teaching the Grand Sorcerer spells!

Mu Ying'er spoke very quickly, and she finished in less than 5 minutes.

"Look!"

Mu Ying'er recited a few cutting-edge incantations, and the entire white fingers of her left hand all turned purple and black, exuding a faint black aura.

"It really worked!"

Gu Boyun was dizzy for a while.

Not only was the spell built successfully, but the spell template was flawless, as if it had been perfected and patched a thousand times, and there was not a single flaw in it.

"What about this spell?"

"This is a level 0 spell [Black Mist Technique], and this one, a level 0 spell [Absorption Touch], and this ......"

Mu Yun taught Mu Ying'er spells for a while, although Mu Ying'er didn't pay much attention, but she was very talented, ordinary spells can be learned and mastered once, and she has already learned seven or eight level 0 spells. These apprentice spells are a piece of cake for Mu Ying'er, who has a special physique, is very sensitive to dark energy, and can sometimes even take the initiative to modify the spell to achieve the most suitable form.

Mu Ying'er has been studying with Mu Yun for a while.

She knew very well that this kind of spell was nothing to Mu Yun, and Mu Ying'er was going to sort out the spell aside, and write it into the next volume of "Mu Ying'er's Notes" together with her own perception and practice results.

Since this old man can enter the house, most of them are young masters' guests, so it doesn't matter if he tells him.

"Good...... Great......" Gu Boyun couldn't be more excited, "How deep is Master Mu's magic attainment?"

Mu Ying'er shook her head and said, "I don't know, nothing can upset him anyway!"

Gu Boyun hurriedly asked: "I don't know what Master Mu's temper is, will it be abrupt to ask for spells......

"Master Mu's knowledge is not something that can be learned if you want to!" Mu Ying'er touched her chin and suddenly said: "Master Mu has a student besides me, and he only teaches us two." ”

"Can I learn?"

"Well...... Master Mu is very good, if he just points out, it should be fine! But if he wants to learn a lot of things, he probably has to be like me, so let's apprentice first!"

Apprentice?

Gu Boyun was stunned for a moment.

This is something that I haven't thought of, but if you can really learn it, what's the harm in apprenticeship? The study of the art is endless, although Gu Boyun is a lot older, as long as he has not yet fallen into the coffin, then there is countless knowledge waiting for him to learn.

If you become Mu Ying'er's apprentice, you will be able to learn the most advanced demon knowledge in the local area and even the Northland Federation...... Gu Boyun is willing!

"I'm willing to be Master Mu's registered student, will she accept it?"

Mu Ying'er was just about to bite the sugar gourd, when she suddenly heard this, she was stunned, her eyes were round, and Nuo stared at him: "Old ...... Grandpa, don't be kidding! You're so old, Master Mu may be a little younger than you think, so it will look so twisty, it's not suitable......"

Master Mu is a little younger than he imagined?

Gu Boyun didn't care: "Even if it's a few years younger than me, we study the Dao of Arts, learning is the first, don't be bound by secular concepts!"

"But, but ......"

Gu Boyun had an idea: "Little girl, help me, Gu Boyun is not a big man, but there are not many things in Baicheng that can make it difficult to get me, I can give you whatever you want." ”

At all costs!

This Mu Ying'er, he is determined!

If nothing else, just to learn the most advanced knowledge of the dark arts!

Gu Boyun ...... Ying'er hadn't heard of it.

This old man is a lot older, and he is still so obsessed with learning, which is indeed worthy of respect.

However, with Mu Ying'er's understanding of Mu Yun, most of them would not accept him, but she couldn't bear to hit him, so she had to say euphemistically: "Okay, if I can help, I will definitely help you." But if it doesn't work out, don't blame me. ”

Gu Boyun showed a look of joy, "A word is a certainty!"

With the help and introduction of Master Mu Ying'er's students, it should be much easier!
