After class the next day, Herrenfen mentor asked Notan to stay.

"Nottan, do you know who was the one who fought with us yesterday?"

"Who is it? Are you very famous?"

Herrenfen nodded with a serious expression and said, "He is one of the five top alchemists in this world!"

"The world's top five alchemists? Is Dean Hassan too?"

"Well, the five alchemists each have their own titles, namely the Alchemist of Flame, the Alchemist of Wind, the Alchemist of Thunder, the Alchemist of Poison, and the Alchemist of Holy Alchemist!" Helunfen paused a little, and then said: "The Alchemist of Holy is Dean Hassan. He is the most recognized alchemist in the world. The one we met yesterday was the Alchemist of Poison, his real name is Lou Qi, and the legendary level exceeded level 70 decades ago!"

Notan was very surprised. He didn't expect that the black-robed alchemist was so big. But then he thought that the ability of Tutor Helunfen to draw with an alchemist of this level means that Tutor Helunfen also has that strength?

Notan asked in confusion: "Why did the tutor tell me this?"

"Of course I'm not afraid of him, but you are different from Notan. After graduating from academy, you always have to travel around the world and start leveling. It's not a good thing to make enemies with such a person at the beginning!" Helunfen said with concern.

But Notan didn't take this matter to heart and smiled and said, "I'm just a little person. I guess in a short while, the poison alchemist Lou Qi will forget me."

"Impossible! Your explosion definitely impressed him!"

"There is nothing to do. The soldiers come to block the enemy, and the water comes to cover the enemy's earth." Notan seemed to care.

"The last explosion, if it weren't for no surprise, it would be impossible for Lou Qi to be hurt. Moreover, it took a long time for you to prepare those things."

"Yeah!" Notan smiled slightly and said, "But it will be made soon in the future!"

Herrenfen looked at Notan's carefree expression and sighed in her heart. She knew that her students obviously had not realized the other party's horror, but she also knew that for Notan now, even if he knew the other party's strength, there was no way.

"Speaking of it, Notan, how did you make that strong explosion?"

Notan knew that Helunfen would be curious about asking, but he did not intend to hide it from Helunfen, so he honestly said: "While practicing alchemy, I accidentally discovered that as long as charcoal, saltpeter, and sulfur were mixed together in a certain proportion, a new powerful explosive drug could be formed, which I called gunpowder!"

"Gunpowder?" Herrenfen smiled slightly, looking very interested, "Do you have any other interesting discoveries?"

"There are some, but you may not understand a little."

"How come I don't understand if you don't say it?" Helunfen said angrily, thinking that there is no such student in the world who ignores the teacher.

"I discovered the principle of electromagnetic power generation!" Notan laughed. In fact, he just took over the daily inventions he had previously on Earth for future alchemy.

"What is the principle of electromagnetic power generation?"

Notan explained a little, but Helunfen couldn't understand at all. Notan had to take out the small power generator he had made with alchemy. After shook it hard for a while, bursts of electric sparks appeared at the end of the wire. Helunfen was extremely surprised to see it and finally fell into silence.

"Nottan, before I met you, I always thought I was the top genius in the world, but after I met you, I realized that my genius was simply incomparable to you, and it even seemed very ridiculous."

Seeing that Helunfen was a little depressed, Notan thought that he was showing off a little too much, and immediately said, "Teacher, you are a genius of the Great Dao, and I am just a slight path."

Helunfen shook his head and then said, "Scientific research on magic is not divided into big paths. Perhaps in the eyes of others, your research on gunpowder is not worth mentioning, but in fact, the power of this gunpowder exploded and injured an alchemist who was nearly level 70. How could ordinary magic have such power?"

Notan wiped his nose and giggled.

Helunfen looked at the boy in front of him with a handsome face and cunning everywhere. He was not tall, but he gave people a feeling that he could rely on. His intelligence no longer needed any proof, and his genius was far beyond the imagination of mortals - perhaps, he was really the one who was destined to help him.

However, after hesitating for a while, Helunfen still did not speak, just said, "Nottan, I have seen the mathematical and geometric problems you explained to Elsa. There are a few of them. Although I have carefully studied them, I still don't understand them very much. Are you willing to teach me?"

"If you have such an idea, I naturally don't dare to hide my own personal feelings!"

Herrenfen seemed very happy and quickly took out the collection of topics.

When Notan saw that it was about functions and limits, he solved the problem immediately, which surprised Herrenfen.

"Nottan, where did you learn this knowledge?"

Notan smiled mysteriously, "I knew it when I was born!"

"Come on!" Helunfen patted his head hard, and then said to himself: "I didn't expect that Dean Hassan's mathematical research to reach such a level!" She obviously regarded these things as Dean Hassan's research.

Nortan was too lazy to explain, after all, these are just far beyond this world. If this era is exposed too much, I don’t know what kind of freak it will be regarded as.

Next, Helunfen took out several questions about space geometry. While explaining to her, Notan also began to ask about some formation combinations and element control techniques. The master and apprentice asked their own questions and answered them. If someone looked at them, they would definitely feel that they were inconsistent with the foreword, but the two people in the game were happy.

I don’t know how long after, when Notan felt a little tired, Helunfen still seemed excited. Smelling the fragrance of Helunfen’s hair and looking at his delicate face that was close at hand, Notan suddenly became a little distracted.

Because this is in the teaching area of ​​Herrenfen's mentor, only Elsa and Nortan can come in, so Herrenfen has always worn it casually. The robe on her body is similar to a nightgown, and she is tied up with a ribbon at will. The nightgown is not long. She sat casually, and her two slender and white legs were exposed to Nortan's eyes. What's even more fatal is that when Herrenfen was excited, she liked to lift her slender legs slightly, which added to the temptation.

Before traveling through time, Notan was a high school student with hormonal surplus, and after traveling through time, he was an uninformed rookie. Seeing the best body in the world and such a slim and orderly body, he couldn't help but react, and when answering Herrenfen's question, he became a little hesitant, and even the question was incorrect.

"You are indeed the same as Elsa said, bastard sex | ghost!" Helunfen was like a little girl, angrily smashed the notebook in his hand against Notan's crotch. Seeing Notan gritting his teeth in pain, she stomped her feet proudly and walked back to the inner room.

Notan was at a loss, thinking that the crime he had committed was a big deal. But then he thought, mentor Helunfen did not look obviously disgusted. Besides, she was so beautiful, and it would be strange if she could not react as an adolescent man. He was thinking about whether to leave first, but he felt that running away like this seemed too rude, but stayed. What if mentor Helunfen didn't come out? If he came out, he and she would be embarrassed, right?

Notan felt as if he was being caught by a monkey, so he made a decision. If instructor Hellenfen didn't come out within ten minutes, he would leave first, and as for the next time he came to class, he would pretend that nothing had happened.

In less than three minutes, Helunfen walked out of the inside. She changed into a slightly formal dress, but it was still silk. Notan looked up like this and found that under the influence of light, she could actually see Herlunfen's body in the robe. The most important thing is that she didn't seem to be wearing underwear yet!

Notan's nose bleeding almost came out, and he was only thinking about one thing in his mind. Is this the temptation of the mentor? Should he pounce on it?

Will Helunfen be knocked into pieces by slag when he pounces on him? If he can touch it, it is worth it to be knocked into pieces, right?

But unfortunately, although Notan has a lustful heart, he has no lust. After all, the crime of blaspheming the mentor is too great.

Herrenfen looked very calm, looked at Notan with a smile and asked, "Are you interested in my body?"

Notan was honest, "Well! But the students only admire the tutor. The tutor is like a goddess in heaven. The students only dare to look up to him and dare not have any blasphemy!"

"Your look is not looking up!" Herrenfen smiled slightly, then waved his hand, and said, "Natan, you go back first, remember to come to class on time the day after tomorrow!"

"Yes, mentor!" Notan was a little disappointed, thinking that if Helunfen, you would never refuse me, why should you be reserved? Of course, he did not overestimate his charm. Helunfen is an old fairy who has lived for a hundred years. He has seen more men than he has eaten rice. Helunfen has seen more excellent men than he has just grown sparse hair in his crotch. Why do he think that he is interested in him because of her provocative words?

He suppressed his emotions and walked out of the teaching area of ​​Helunfen's instructor. Looking back at the three-story white building, he suddenly felt infinite emotion - this may be youth, this may be the first opening of Hongmeng.
