There are 1,672 staircases in Santiago, some of them are spacious and clean, some are old and narrow, and some are always shaky, some lead to other floors at certain times, and some even hide some disappearing stairs, either using the Movement Skill to get through Guò or detour.

The doors here also change from time to time, you don't know if the door you open is behind the inscription class, the magic class, or the engineering class, or just a hollow black room, and even some doors are not doors, but just look like the walls of the door.

Not only these problems, but there are also imps in this academy, yes, they are troublemakers like Pivis, I really don't understand what kind of mentality allows these nasty things to exist in this school!

Karel withdrew his foot, kicked the little ghost who was trampled on the ground into the dark room in front of him, and then slammed the door shut, just now, the moment Karel opened the door, the little ghost turned into a strange human face and floated over, making a burst of terrible crying, which scared Karel a lot, and then, the little ghost was slapped to the ground by Karell, and he was crushed hard, although it was not to death, but it was enough to bear.

Karel signed up for the alchemy and assassin majors, which were 9:30-11:30 in the morning, and 2-4 in the afternoon, and the time in this world is strikingly similar to the earth, 24 hours a day, 7 days a week, 30 days a month, 360 days a year, so it saves Karel the effort of converting time.

After wandering the labyrinthine academy for half an hour again, Karel finally found a classroom before class. It turned out that the classroom where alchemy was taught was actually in a basement. Then again, only the basement can withstand the constant contingencies of the alchemy course.

"Alchemy is one of the most dangerous courses taught in this school, we say ugly things in front, if you make trouble in class, just get out and never come back!" It was Professor Connorth who taught alchemy, as he said in the first sentence of the first lesson.

"You're here to learn the precision techniques of pharmaceuticals, elemental conversion, and metal synthesis." Connorth said, her voice high and stern, as deeply engraved in everyone's mind as a knife, and Professor Connorth had the magical power to easily keep students quiet. "Think about it, when you use a beaker to steam the herbs, the potion slowly boils, and white smoke rises...... The transformation of the elements, the blending of water and fire...... The synthesis of metals, the synthesis of strange substances into even more amazing substances...... It will simply enchant all your senses! ”

Listening to Connors's call, the professor became even quieter, and it was almost like a pin drop.

"Karel!" Connorth suddenly called out to Karel, "What will I get if I add rootgrass powder to the sap of the tranquilizer flower and dilute it twice with water?" ”

"Hmm... It's a weak troll blood potion, right? Karel thought for a moment and replied. The Tranquilizer has healing properties, and the Root Grass causes the effect of the Tranquilizer to be cast slowly, causing the drinker to remain in the healing effect for a long period of time, just like the trolls who can heal themselves.

"Good," Connorth nodded, motioning for Karel to sit down.

"Horn, if I need a purple lotus, where can I get it?"

"Primeval forests, or natural elemental creatures, but this herb is very rare." It was the bespectacled cadet who stood up to answer, the same one who had met Karel on the dock where he had come aboard.

"Very good, so one last question, what would you do if you were poisoned here, but you didn't know what kind of poison you had? Millie, you answer. ”

It was a little girl with long blond hair who was called, "I'll go find swift grass, which is the nemesis of most poisons." ”

Bang Bang Bang! Connorth applauded, "Great, it seems that you have all been very well prepared, and I am very happy about that, okay, let's try it out, alchemy is a course that requires a lot of operation, and you can't conjure a bottle of potion out of thin air with the knowledge in the book alone." ”

In the next few lessons, Connorth had the students work in pairs and taught them how to make a simple ointment for injuries that heals minor injuries in a very short time, as well as several different ways to make this ointment.

"There are more than two ways to make any potion ointment, you must keep in mind this, nothing is impossible in alchemy, and I can even use pot water and honeysuckle to make powerful healing potions." Connorth walked between the alchemy tables in her dark green robes, directing the students' movements.

"Don't lower your head too low when grinding, do you want to eat the powder of the Demon Emperor Grass?"

"The heating test tube must be preheated first, otherwise it will burst directly."

"Steamed herbs should be chopped first so that the effect is best. And use the water bath method, otherwise the overheated water temperature will ruin the effect of the potion! ”

……

A honeysuckle, chopped, added to 200 ml of water and steamed until bright yellow, then added silver leaf grass crushed to continue to cook until red, filtered out the dregs, poured the uncooled liquid into the melted gelatin, and then stirred until cooled into a paste, and then poured into a soft crystal bottle (an alchemical material, similar to plastic) as a whole, no air, sealed well, so that the trauma ointment is done, if it is sold, at least two silver coins a bottle. After all, this can only heal a small amount of trauma.

In addition, there is also the use of dried urticaria, plus snake bone powder, demon king grass powder, swift grass juice, with large slugs as the matrix, to acidify it into a green paste, the effect is one-third better than that of honeysuckle, and there is a detoxification effect.

Of course, it was not without accident, when it was about to end, the girl in the group with Millie, who seemed to be called Hearns or something, didn't know what to do, and burned the beaker hard, and the hot liquid splashed everywhere, and the two girls were startled.

"Fool!" Connorth shouted, "The powder of the ground root grass is mixed with the powder of the golden beetle and heated to have a deflagration effect!" By the way, where did you get the golden beetle? I didn't provide this material in this class. Connorth sniffed the air and pinpointed the cause of the accident.

The three of them turned pale. Connorth was angry, and the two girls were scared

"Alright, now class! Everyone extinguishes the magic furnace, cleans the utensils, and returns to their places before leaving, and the ointment they have refined can be taken with them, remember to close the door. You two come with me. With that, Connorth took the two girls and walked straight out of the classroom.
