The Last Alchemist

Time passed minute by minute, Veronica lay prone on top of the parchment, her eyes fixed on the picture on the parchment, her body motionless.

Thanks to her, Rosen was unable to move. He felt uneasy, but he was unable to do anything, so he could only wait passively.

Of course, this is not without its benefits. With the current postures of both parties, Rosen can enjoy the white rabbit in front of him in a dignified manner. However, although the scenery is

Beauty, but the situation was worrying. Under the stimulation of hormones, Rosen lost interest after taking a few more glances.

He lamented in his heart: 'This world is really unfathomable, there is such a super strong man hiding in any small town. If I encounter a monster of this level, even if my alchemy reaches the top level, my life will still be hanging by a thread. ’

I don’t know how long it took, but Veronica suddenly let out a sigh of relief.

Rosen was shocked and asked carefully: "Do you understand?"

Veronica nodded slowly: "I roughly understand it. Your thoughts are very insightful."

Rosen relaxed and pointed to the medicine shelf not far away: "Thank you very much for your appreciation. Can I get my reward?"

Veronica shook her head: "Not yet."

Rosen was startled, spread his hands, and said he was speechless.

Veronica pointed to the parchment and said: "As for the phenomenon of moths flying into the flame, you did give an extraordinary explanation and solved my doubts.

However, the old doubts disappeared, but new confusions arose. "

Rosen was even more speechless. He promised to answer a question with just one bottle of potion. He answered it, but the other party refused to let him go. He didn't want to take such a shameless person with him.

He spread his hands on the table: "New confusion, right? Okay, add 1 bottle of potion!"

Veronica couldn't help laughing: "Are you so confident that you can definitely answer my questions?"

"You asked me, I'll answer if I can, forget it if I can't." Rosen's face was full of confidence. With Veronica's level, do you still want to stump him? What a joke!

Veronica was stimulated by Rosen's expression. She immediately picked up the quill, pointed at the curve on the parchment, and said quickly: "Why do the curves when flying insects fly look like this? Instead of other shapes? This What are the characteristics of this curve, and what kind of natural laws are behind it?”

After speaking, she looked at Rosen provocatively.

Rosen immediately picked up the quill and started writing, but after writing for a while, he paused.

"Why, you were so confident just now, but now you can't write it?" Veronica sneered.

Rosen shook his head: "It's not because of this. I just want to make it clear in advance that although I very much hope that the transaction between us can continue, it is too late today. After I answer this doubt, I must Gotta go back."

"I promise you." Veronica agreed.

Rosen picked up the pen and wrote a letter on the paper. After writing, he stopped.

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

Rosen continued to write after e: "Transcendental numbers, natural constants, numbers contained in the deepest part of the natural spiral."

"Transcendental numbers? Natural constants? Natural spirals?" Veronica muttered softly, and as she continued to recite, she became lost.

She didn't understand these three words, but she could instinctively feel that they contained profound wisdom.

It's like a person sees a golden mountain in front of him. He has seen the endless brilliance radiating from the golden mountain, but he can't find the way to the golden mountain and can only wander helplessly under the golden mountain.

Seeing that Rosen was hesitant to start writing, Veronica finally couldn't help but asked: "What next?"

With her own wisdom, she could not reach the top of the Golden Mountain. At this moment, Rosen was no longer an ordinary human boy. At this moment, Rosen was the guide and pioneer who helped her climb to the peak of wisdom! It's a sage!

Rosen lowered his head and drew a cross at right angles on the parchment, and then led a ray from the intersection. The angle between this ray and a straight line is marked A, and the length of the ray itself is marked R.

Then, he wrote an exponential function on paper, and the function contained an e.

Seeing this function, a sense of piety similar to a pilgrim appeared in Veronica's eyes. After looking at it for more than ten seconds, she shook her head: "I don't understand, please explain to me."

Rosen knew that the other party would not understand. He took a deep breath and started explaining from the most basic exponential operation, all the way to the polar coordinate system, and briefly explained the concepts of functions and transcendental numbers. Finally, he said: "In this polar In the coordinates, all the points that satisfy this function are the trajectory of the flying insect fighting the fire. If you don't believe it, you can calculate it yourself when you have time. "

At this point, Veronica was completely convinced, and her eyes looking at Rosen couldn't help but have a dreamy look.

She realized that she was originally stuck in a small world, but Rosen's arrival suddenly led her to the broad sky. This world is filled with countless profound wisdoms, just like a treasure house full of treasures. Picking up a stone from the ground is a treasure that can shock the world.

Just when she was immersed in the glory of the new world, an annoying voice brought her back to reality.

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

"Oh, why should such divine and wonderful wisdom befall such a philistine? What a waste of nature, God!"

Veronica almost went berserk. She really wanted to open this mortal's brain and take a closer look at what was inside.

After finally calming down, Veronica waved her hand: "Take it. The explanation you gave is far beyond my imagination. I allow you to take one more bottle."

"Thank you so much!" Rosen was overjoyed.

He quickly walked to the wooden shelf of alchemical bottles. The medicines on the shelf were labeled. He looked at them one by one: "Charcoal, mercury, saltpeter, sulfur, glycerin, lead, griffin acid, isn't this a mixture of nitric acid and sulfuric acid? Tsk, it really has everything, but it's a pity that I can only take 3 bottles."

The iron pipe is already there, and what is needed next is gunpowder. Rosen thought about it and finally chose griffin acid, lead, and mercury. These three things cannot be obtained in Sunderland Town and are all very useful.

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

Looking at the medicine bottle in Rosen's hand, she said: "Mercury? If you are going to use it to treat rose spots for that lustful baron, then I have to tell you that you are making a wrong decision."

"Ah?" Rosen was a little unresponsive, and after a few seconds, he fully understood what Veronica said.

On Earth, in medieval Europe, people thought of many strange ways to treat syphilis. Among them is a "mercury vapor method", which is very simple, that is, to let the patient enter a wooden barrel filled with mercury vapor.

For syphilis spirochetes, this method is of course useless. However, for syphilis patients, this method can solve their pain once and for all and allow them to ascend directly to heaven.

Now listening to Veronica's words, it is estimated that there are similar treatments in this world.

After thinking for a while, Rosen shook his head and said, "No, I have another way to treat roseola. As for this bottle of mercury, I have another use for it."

Veronica laughed: "Another way to treat it? Oh, haha~~May God bless the Baron."

Rosen could easily feel Veronica's contempt, but he was too lazy to explain. He carefully put away the three medicine bottles and asked, "Can I go back?"

"Oh~ Of course." Veronica stretched lazily, picked up the cup on the table and drank a sip of water: "Your explanation is very wonderful, and I am very satisfied. I can see that you must know much more than this. So, if I have a problem that I can't figure out in the future, I will come to you again."

Rosen's eyes paused on the cup, and his heart moved slightly: 'Drinking water with 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. Then, he was put on the black hood again, and the whole person suddenly became lighter and flew up.
