The sky was already bright, the clouds had dispersed, revealing the warm sun, the rooftops, the ground, all shining, last night a rain, so far, the rain has finally cleared.

Last night, in the heavy rain, the Grand Dean and Dean Fairlando returned to the academy, although they used the "Time Travel" spell, but because the rain interfered with the spell, they didn't see who it was, but vaguely saw the appearance of a boy in a white robe. This white robe made the dean confirm that this person was not a student of the Elemental Magic Department, and the Magic Elemental Department had its own magic robe, which was forbidden to wear other clothing. After discussing with Ferlando last night, the two were ready to investigate privately.

・・・・・・

The wind was beautiful, and the air was filled with the smell of earth, and Victor and his brothers came out of the dormitory and prepared to go to the school building. There was no Karina's class today, but it was everyone's favorite alchemy class, so everyone was excited.

Along the way, everyone was already discussing the content of today's lesson.

"Boss, in the last class, Mr. Igor asked us to prepare a corrosive potion, you can show me your formula!" This is Bigg's voice, Victor's fat friend.

"Fatty, this is a corrosive potion that I have carefully studied, take a good look at it!" said Boss Frank as he handed over the parchment in his hand.

Last night, Victor got to know everyone again, and also knew the relationship between everyone and himself, and seeing that the fat man was so excited, he also leaned in to take a look. I saw that it was written: three wild steel flowers, a pair of bat wings, a snake sac, a little gum, conch slime, and a bottle of Geda elixir.

After looking at this thing, he also looked at the other people's recipes. Everyone wrote some recipes for bats, poisonous insects, etc., and Victor took them all to heart. Alchemy does not require magical support, as long as there is a subtle recipe can exert great power, and by this day, he already knows several legends of alchemy.

Three hundred years ago, there was an abyss alien attack, and the god-level alchemy master used the blood of the dragon as the recipe to make the dragon knight potion.

There are god-level alchemists, who take hundreds of poisons as formulas and refine the Elixir of Death, which is like a plague, and the demon will die when he touches it, and he will die when he touches it, even if it is the demon spirit.

There are god-level alchemists, who use the elven ancient wood as the formula to make life elixirs. It can prolong the life of people, and people who are 100 years old will not fail.

Knowing that he had no talent for magic, Victor also put his mind on alchemy, and he was also looking forward to coming to the real first class in this world.

Before they reached the Alchemy Building, Victor could already smell it, and they were not far from the Alchemy Building. In the air, the smell of disinfectant water wafted from afar.

When they arrived at the teaching building, they saw that their classroom had not yet opened, and their alchemy course teacher was late.

"Teacher Igor is here. Haha, it looks like the teacher must have drunk too much last night. Look at his chest, there's a big stain of wine!" There was a burst of laughter in front of the classroom door, and a middle-aged man with a big belly walked in the distance.

Frank laughed too, and he joked, "Fatty, in a few years you will be exactly like Teacher Igor." ”

Igor also saw everyone in the distance, although he was a little embarrassed and dizzy, at this time, he had to open the classroom door hard, he was just a "newcomer" who had just passed the intermediate alchemist exam, and he didn't dare to pretend to be a powerful person.

When the door was opened, everyone also entered the classroom and took their seats, and Victor was stunned when he looked at the dense test tubes in front of him, which made him suddenly feel like he was taking a chemistry class in a classroom on Earth.

On the podium, Mr. Igor cleared his throat and opened his mouth: "Today we are making corrosive potions, and everyone can start." An hour later, I came to check that the best students who had completed today would be exempted from the task of cleaning up the lab bench this semester. ”

On the podium, Mr. Igor sat down with that, leaning back in his chair, he yawned a lot, and his eyes were half-closed. He had drunk too much fresh ale last night, and had not rested well all night, and he was already sleepy. Seeing that Teacher Igor was asleep, everyone began to communicate in a whisper, and the reason why they liked alchemy could be said to be mostly because of Igor. Because only here can they blatant plagiarism. Unlike other teachers, Igor's favorite phrase is: if you don't want to use your brain, just copy the best copy in your head. This is much more amusing than the teacher of the earth.

Igor snorted on the podium, and the students in the classroom began to select materials. In front is the laboratory bench, and behind the classroom is the material warehouse. Frank finished selecting his materials and opened his mouth with some doubts: "Victor, are you going to disinfect the utensils with disinfectant water?"

I saw Victor holding a bottle of disinfectant and a large yellowish stone in his hand.

"Boss Frank, I'm not here to sterilize, you'll find out later. Victor smiled and walked away with a bit of mystery.

Starlight Continent doesn't have a periodic table, and Victor isn't sure if this disinfectant is that thing, but since he has encountered it, he wants to try it first. This pungent smell is exactly the same as that thing on the earth, and it is the same as the "84" used to disinfect on the earth.

Lighting the "alcohol lamp", Victor poured this disinfectant into a test tube, he was purifying, the general disinfectant water was not strong enough to make that thing, Victor didn't want to fail, on the "alcohol lamp", the disinfectant began to slowly decrease.

The most famous corrosive agent on earth is sulfuric acid, and Victor is preparing to make sulfuric acid today.

In chemical reactions, sodium hypochlorite oxidizes sulfur. Its chemical formula is: S+3NaClO+H2O=3NaCl+H2SO4. In words, sulfur and sodium hypochlorite can be used to synthesize sulfuric acid and sodium chloride.

The test tube was almost purified, and Victor added the sulfur ore to the purified disinfectant water. Not long after, a pungent smell was in the air, which was chlorine gas. Sulfur ore and disinfectant water are heated to produce a new reaction. Sodium hypochlorite is excessive, and the product sodium chloride is further reacted to form chlorine gas, which Victor naturally knows this, and adds some sulfur ore, and the smell gradually disappears.

Picking up a piece of filter paper from the table, Victor threw it directly into the potion he had made, only to see that the filter paper was "on fire", and the original white paper was as if it had been ignited by fire, and it had a chemical reaction, turning black and made of sulfuric acid.

The sulfuric acid was finished, and Mr. Igor also woke up, and today he was not feeling sick in his stomach, and after looking at the time, he said, "Let's stop here today! Everyone put their potions on the table, and I will check them." ”

If you can't finish the potion, you have to sweep the laboratory, most of the civilian students have completed it, and most of the noble students have completed it. According to Victor's rough estimate, twenty or thirty students have completed the potion.

"Oh! It's definitely the most disgusting potion I've ever seen. Teacher Igor jokingly shouted loudly in the first row.

I saw that someone had smashed poisonous snakes, poisonous scorpions and other things into a mess, and it was very disgusting. Today is a corrosive potion class, not a disgusting potion class, and Mr. Igor decisively gave a fail.

Roughly halfway through, Frank's potion was really taken by Mr. Igor.

"Yes! It's already a fine of primary potions. Teacher Igor touched his mustache, smiled slightly, and gave an excellent.

"Haha. Victor, you have prepared a glass of water for me. Do you want to quench my thirst?" and Mr. Igor laughed out loud in his elegant, joking tone.

"Teacher, this thing is not clear water, just pour it on the table. Victor knew that Mr. Igor liked to joke and played a joke with him.

"Okay, I'll listen to you today. "It turned out that Vidor loved to joke, and when Mr. Igor saw Vidor's words, he thought that Vidor was joking with him again, so he stretched out his hand and poured the thing on the table.

On this table, there was a large clean covered cloth, and sulfuric acid was poured on it, and I saw that this cloth had become a "monster".

A good cloth was quickly "burned" out of a large hole, and a drop of sulfuric acid splashed on Mr. Igor's sleeve, which was also "burned" black.

After swallowing a mouthful of saliva, Mr. Igor had goosebumps all over his body, he never thought that this thing that looked like clear water would have such a strong corrosive force. Almost, only closely, he was about to let go of the beaker in his hand, and he was "scared to pee".

Slowly putting down the beaker, Mr. Igor's face flashed red, looking at the cover, and then at Vidor, he shouted with all his strength: "Today, Vidor has created a miracle. This is definitely the most perfect corrosive potion we have ever made in our class. ”

Standing beside Vidor, Frank naturally saw the change of the tablecloth, and he was also excited, and he was still imagining in his mind that if Mr. Igor really drank this cup just now, I am afraid that he would not be able to see the sun tomorrow.

Everyone heard Teacher Igor's voice and gathered around, and everyone also saw this "terrible" scene.

"Victoria, this thing can definitely be exchanged for a large amount of points in the Alchemy Guild, you really did a great job this time. "You know, Vidor is Igor's student, and if Vidor submits this thing to the Alchemy Society, then Igor will also get a lot of benefits.

In this world, the relationship between teachers and students is much closer than in the previous life, one is prosperous, and the other is lost, except for parents, wives and children, in this world, the most intimate relationship is master and apprentice.

Victor was also blinded by such a high evaluation from Mr. Igor, and he didn't expect that this simple chemistry experiment could get such a high evaluation.

"Victor, if you're okay after class, we can just go and submit this potion. By the way, what is the name of this potion? ”

"Sulfuric acid agents. Listening to Igor's words, Vidor nodded, and also said the name of the potion in passing.

"Forget it, get out of class early. Anyway, tomorrow is a holiday, tonight, let's go to Old Gre'a to celebrate!" Igor waved his hand and said happily.

Old Grey is the name of the owner of the bar across the street from the school, where there is the freshest ale, which is Igor's favorite.

"Victor. Let's go with Mr. Igor and submit the potion! When you get back, we're going to slaughter you. Frank reached out and patted Victor on the shoulder, revealing his thumb.

Although he didn't know what he had done, seeing that Frank and Igor attached so much importance to this thing, he probably knew the value of this thing, nodded his head, and Victor also spoke: "Students, let's go together at night!"

When they heard this, they all laughed. Packing up the rest of the potion, Igor and Vidor set off. Frank and the others looked at Victor's back, and they all sent their blessings from the heart, and there was a round of applause in the classroom.

PS: In particular, the "alcohol lamp" of this world is not fueled with "ethanol".
