As the minutes ticked by, Veronica lay on her stomach on top of the parchment, her eyes fixed on the picture on the parchment, her body motionless.

Thanks to her, Rosen was also unable to move, he was uneasy in his heart, but he was not as strong as others, so he could only wait passively.

Of course, this is not without benefits, with the current posture of both parties, Lawson can admire the white rabbit in front of him, but the scenery is although

Beauty, but the situation is worrying, under the stimulation of hormones, Rosen took a few more looks, and then he was happy.

He lamented in his heart: 'This world is really unfathomable, and there is such a super strong man hidden in any small town. If I encounter a monster of this level, even if my alchemy skills are promoted to the top, my fate will hang by a thread. ’

I don't know how long it took, but Veronica suddenly let out a soft breath.

Rosen was shocked in his heart and asked carefully, "Do you understand?" ”

Veronica nodded slowly: "I have roughly figured it out, your mind is extremely insightful." ”

Rosen was relieved, and stretched out his hand and pointed to the medicine shelf not far away: "Thank you very much for your appreciation, then can I take my payment?" ”

Veronica shook her head: "Not yet. ”

Lawson was stunned and spread his hands, indicating that he was speechless.

Veronica pointed to the parchment and said, "You have indeed given an extraordinary explanation for the phenomenon of moths fighting fires, and have solved my doubts.

However, when the old doubts disappear, new ones arise. ”

Rosen was even more speechless, saying that he would answer a question with 1 bottle of potion, and he answered, but the other party didn't let him go, so he didn't bring such a trick.

He spread his hands on the table: "New confusion, huh?" Yes, add 1 bottle of potion! ”

Veronica couldn't help but laugh: "You're so confident that you will be able to answer my question?" ”

"If you bring it up, I can answer it, and if I can't, forget it." Rosen's face is full of confidence, just with Veronica's level, do you still want to stump him? What a joke!

Veronica was stimulated by Rosen's demeanor, and she immediately picked up a quill, pointed to the curve on the parchment, and said, "Why does the curve of the flying insect fly out like this?" And not something else? What are the characteristics of this curve, and what kind of natural laws are behind it? ”

After saying that, she looked at Rosen defiantly.

Rosen immediately picked up the quill and prepared to write, but after writing a little, he paused again.

"Why, I was so confident just now, and now I can't write it?" Veronica scoffed.

Rosen shook his head: "It's not because of this. I just want to make it clear that while I'd love to see the deal between us go ahead, it's too late today, and I'll have to go back when I've answered that question. ”

"I promise you." Veronica agreed.

Rosen picked up a pen and wrote a letter on the paper, and when he was done, he stopped.

Veronica looked over and couldn't help but read: "e..... What does this mean? ”

Rosen goes on to write after E: "Transcendental numbers, natural constants, numbers contained in the deepest depths of the natural spiral. ”

"Beyond the number? Constants of Nature? Natural spirals? Veronica whispered, and as she read it, she was lost.

She didn't understand these three words, but she could instinctively feel that there was deep wisdom in them.

This is like a person who sees a golden mountain in front of him, and he has seen the endless brilliance emanating from the golden mountain, but he can't find the way to the golden mountain, so he can only wander helplessly under the golden mountain.

Seeing that Rosen was slow to write, Veronica finally couldn't help it: "And then? ”

With her own intelligence, she could not reach the top of the golden mountain, and at this moment, Rosen was no longer an ordinary human teenager. At this moment, Rosen is the guide who helped her climb to the peak of wisdom, and he is a pioneer! It's a sage!

Rosen bowed his head and drew a cross on the parchment that intersected at right angles, and from the intersection drew a ray from the intersection point, the angle between this ray and a straight line was marked A, and the length of the ray itself was marked R.

He then writes down an exponential function on a piece of paper, and the function contains an e.

Seeing this function, Veronica's eyes had a sense of piety similar to pilgrimage, and after looking at it for more than ten seconds, she shook her head: "I didn't understand, explain it to me quickly." ”

Rosen knew that the other party would not understand, so he took a deep breath and explained from the most basic exponential operation, all the way to the polar coordinate system, and then briefly explained the concept of functions and transcendental numbers, and finally, he said: "In this polar coordinate, all the points that satisfy this function, connected together, are the trajectory of the flying insect to the fire." If you don't believe me, you can do the math yourself when you have time. ”

At this point, Veronica was completely convinced, and looked at Rosen's gaze with a dream-like look.

She realized that she was originally confined to a small world, but the arrival of Rosen led her to the wide sky. This world is filled with countless profound wisdom, like a treasure trove full of treasures, and picking up a stone from the ground at random is a treasure that is enough to stir up the world.

Just when she was intoxicated by the splendor of the new world, a nasty voice pulled her back to reality.

"Hey~ I'm going to get the potion?"

"Oh, why should such a holy, wonderful wisdom fall on such a philistine? O gods, this is a terrible thing! ”

Veronica was on the verge of going berserk, and she wanted to open this mortal's brain to see what it contained.

Finally sorting out her emotions, Veronica waved her hand: "Take it, the explanation you gave is far beyond my imagination." I'll give you permission to take one more bottle. ”

"Thank you so much!" Rosen was overjoyed.

He walked quickly to the side of the alchemy vial wooden shelf, the medicines on the shelf were labeled, he looked at the bottle by bottle: "Charcoal, mercury, saltpeter, sulfur, glycerin, lead, griffin acid, isn't this a mixture of nitric acid and sulfuric acid?" Tsk, it's really everything, but unfortunately I can only take 3 bottles. ”

The iron pipe was already there, and then what was needed was gunpowder, and Rosen thought about it, and finally chose griffin acid, lead lumps, and mercury, all three things that could not be obtained in Sunderland Town, and all of them were of great use.

After choosing, he turned to look at Veronica and saw that she had recovered from her daze, but was still contemplating.

Looking at the medicine bottle in Lawson's hand, she said, "Mercury? If you're going to use it to treat that baron for rosacea, then I'll tell you, you're in the wrong place. ”

"Huh?" Rosen didn't react a little, and was stunned for a few seconds before he fully understood Veronica's words.

On Earth, in medieval Europe, people thought of many strange ways to treat syphilis. One of these is the 'mercury steam method', which is simply by putting the patient into a wooden barrel filled with mercury steam.

In the case of Treponema pallidum, this approach is of course useless. However, for syphilis patients, this solution can solve their suffering once and for all, and allow them to ascend directly to heaven.

Listening to Veronica say this now, it is estimated that there are similar treatments in this world.

After thinking about it, Rosen shook his head and said, "No, I have another way for rosacea. As for this bottle of mercury, I have another use. ”

Veronica smiled: "There is another cure? Oh hehe~~ May the gods bless the baron. ”

Rosen could easily feel Veronica's contempt, but he didn't bother to explain, and carefully put away the three pill bottles, and he asked, "Can I go back?" ”

"Oh~ Of course." Veronica stretched lazily, picked up the cup on the table and took a sip: "Your explanation is very wonderful, I am very satisfied. I can tell you that there's a lot more to you than that. So, if I have any questions that I can't figure out, I'll come back to you in the future. ”

Rosen's eyes paused on the cup, and his heart moved slightly: "Drink water from a silver cup?" ’

Before this thought fell, he saw a red shadow flashing in front of him, and a faint fragrance came to his nose, and immediately after, he was once again put on a black hood, and the whole person suddenly lightened and flew up.
