"Teacher, I'm back!"

Leng Feng, who entered the magic tower, first said hello, but Kasgu and Tuoketo were still so busy that they didn't even look at themselves, which made Leng Feng slightly embarrassed!

"Boy, it's almost time to cook!"

Just when the cold wind was slightly deflated, Tuoketo on the side suddenly said without raising his eyelids.

"I know that's the case, I'll be your exclusive chef!"

Although he couldn't help but feel a bit of slander in his heart, Leng Feng didn't say anything rationally, but went into the kitchen very resignedly.

After a busy time.

Looking at the two old men who looked like they were gobbling up without any image, Leng Feng almost thought that they hadn't eaten anything at all these days, although they looked indifferent on their faces, but they were slandered again in their hearts.

Eat, eat, don't choke!

"Boy, you're almost at the level of a magician, aren't you?"

After Kasgu, who was finally satisfied, wiped away the greasy on his mouth, his face returned to his previous serious appearance, and he suddenly asked as he looked at the cold wind.

Could it be that the sun is coming out of the west today?

I didn't expect this old guy to care about himself, Leng Feng couldn't help but be slightly stunned, but he still replied honestly.

"It's still a kick in the door, but it's almost there!"

"Well, your true strength should be almost at the level of a high-level magician!"

After nodding noncommittally, Casgu continued.

After all, Leng Feng has a weapon like derivative magic, coupled with the ability to instantaneously generate magic, it is almost invincible in the same level, even if it is a leapfrog challenge, so Casgu's estimation can be said to be very accurate.

If this were to be changed to another teacher, I am afraid that I would be able to get such a talented student, I am afraid that I would not be able to sleep happily, and I must have attached great importance to the cold wind, but whether it is Kasgu or Tokto, their faces are all unwavering, as if they are stating a reasonable fact.

This couldn't help but make Leng Feng's heart once again give birth to a faint sense of frustration!

But now he also knows that these two old men are characters who like to pretend to be B very much, and their inner thoughts are easily unwilling to show, so soon after this trace of frustration disappears, they forget it.

"Then it's almost time to start a new course!"

After glancing at Tokto on the side, Casgu suddenly said.

Pharmaceutic!

Like magic, pharmacy is an extremely old and long-standing discipline on the continent, and those who master it are called pharmacists.

However, after thousands of years of multiplication, although the discipline of magic has been continuously promoted, pharmacy has gradually begun to disappear, so that it has almost become unknown now.

There is even a slight prejudice against pharmacy, believing that it is an extremely horrific killing technique that only a necromancer who sells his soul to the god of death will be interested in it.

Unexpectedly, the two old men actually let themselves learn this, so Leng Feng couldn't help but look at them with surprised eyes.

As if feeling the doubts of the cold wind, he saw Tuoketo say with a smile.

"You're not wrong! Strictly speaking, the two of us are actually one of the few pharmacists on this continent!"

Leng Feng didn't expect that the two old guys would be so honest and directly tell him such a big secret! And he was no longer the rookie who didn't know anything at the beginning, even if he knew that pharmacy was almost infamous on this continent, but in Leng Feng's opinion, he didn't have any special feelings, but he was more interested in it.

"That's what we've learned about pharmacy for a while, and if you're interested, you can also participate in our experimental research in the future!"

As he spoke, Casgu had already put a thick notebook in Leng Feng's hand, and after a brief explanation, he went back to work again, a typical quick knife cutting mess without the slightest drag.

Although Casgu said it simply, the cold wind had a certain understanding of it, so where could he not see it? This is the last point that the old thing has entrusted to himself without reservation!

I don't know why, there is a faint taste of emotion in my heart.

I was moved in my heart, but in the end, it was two old students, and the cold wind quickly pressed it to the bottom of my heart, opened my notes and began to devote myself to brand new learning.

"This, isn't this chemistry?"

It's just that in the process of constantly flipping through the pages, Leng Feng couldn't help but start to have a trace of inexplicable strange feelings, and it wasn't until he finally realized that he lost his voice.

"What the hell is your name, boy?"

His original inspiration and train of thought were interrupted by the sudden shouting of the cold wind, which made Casgu frown very unhappily and shouted, if this kid was not his favorite student, he might have kicked him out of the laboratory long ago.

However, Leng Feng didn't pay attention to the other party at all, and saw him go straight to the blackboard in the corner of the laboratory, and reached out to wipe the original things on it.

"Rabbit cub, this is Lao Tzu's experimental record, what do you want to do?"

For Leng Feng's action, Casgu couldn't help but be angry and yelled, but just as he rushed forward to teach the other party a good lesson, he was stopped by Tokto.

"Let's see!"

Tokto winked at Casgu.

Oh yes, I forgot that this kid always has some surprises!

Only then did Casgu understand, and it was not easy to have another seizure immediately, anyway, the experimental records he had worked hard to obtain had been wiped clean by the other party, and now he could only read it patiently.

"What is this formula?"

Seeing the rows of alphabet symbols written by the cold wind, Tokto, who had long been accustomed to his so-called derivation formula, immediately said with a light in his eyes.

"It's a chemical formula!"

Leng Feng explained to the two old men without the slightest concealment.

"And this time what I deduced was a chemical reaction process in Fang Cai's pharmacy notes!"

"Well, stinky boy, tell us about it!"

Although he didn't understand the true meaning of these formulas in front of him, he had many years of profound skills, so Casgu noticed the mystery at a glance, and after his eyes lit up slightly, he opened his mouth and ordered.

"Well, we have to start with the meaning of each ion symbol in the formula!"

Leng Feng patiently explained!

If you want to understand the meaning of the chemical reaction formula, you must first understand the meaning of each ion symbol and its own properties, which will take a long time if you really explain it in detail.

Fortunately, these two old goods have a deep foundation in the end, and their acceptance ability can be described as extremely strong, plus the cold wind only selectively explains part of the chemical reaction knowledge.

But even so, the cold wind still took a lot of time, and after the two old guys completely showed their expressions of sudden realization, the sky outside was completely dark, and it was already late at night!

"Boy, your so-called knowledge of chemistry is really thorough!"

Tuoketo shook his head with some emotion and said.

Originally, his attainments in pharmacy can be said to be extremely conceited, but now compared with Leng Feng's so-called chemical knowledge, it is a step worse, obviously not so thorough and direct!

Even some of the problems he encountered in the process of research were deeply analyzed in Leng Feng's explanation, which gave him a sense of sudden enlightenment.

"Boy, sometimes I wonder if you're from this world!"

After also sighing lightly, Kasgu couldn't help but stare at the cold wind and said.

This is really what Casgu said, since the appearance of this kid, not only the derivative magic and the instantaneous talent of magic have made the two of them astonished, especially the derivation formulas he used in the process of studying magic, the more he thinks about it, the more mysterious he feels.

And now this kid has such a great talent for pharmacy, and after the so-called chemical knowledge is displayed, he has a big surprise.

"That...... Don't be kidding! I'm not from this world, where else can I be?"

Unexpectedly, Kasgu coincidentally said his origin, Leng Feng was secretly taken aback in his heart, and immediately made an indifferent look and said with a smile.

"You kid is so mysterious!"

However, Kasgu still took a deep look at the cold wind, and when the other party almost began to be frightened, he suddenly said with a smile on the corner of his mouth.

"This old boy really scared me to death!"

Looking at Casgu's back as he shook his head and left in his head, Leng Feng couldn't help but pat his chest with palpitations and muttered to himself.

In the following days, Leng Feng stayed in the magic tower almost inexorably, and joined the two old potion research in a grand manner.

Originally, as far as he was concerned, he was not qualified to join at all, but compared to the two old guys, Leng Feng had a series of chemical knowledge from his own world, and although pharmacy was more mysterious in comparison, it still did not go beyond the scope of chemistry.

So much so that many questions can often be answered well after resorting to the chemical knowledge of cold wind.

And this also made the second elder more and more inseparable from him, almost every experiment had to pull him to be present! And Leng Feng took this opportunity to compare the pharmacy notes with the actual research, which also benefited a lot!
