Robert walked down the aisle, only to see the door of the first alchemy room closed, and a magic hourglass hung on the door, and the fine sand poured down like water, apparently someone was using this room.

He looked room by room, until he saw the tenth room, his eyes lit up, he saw that the hourglass on the door was still moving, knowing that this laboratory was not used, he took a deep breath, took off the school card, and lightly touched the hourglass.

I saw a flash of magic brilliance, the fine sand in the hourglass slowly flowed down, and with a click, the door opened automatically, and the number on the school card was instantly deducted ten contribution points.

At the same time, a voice suddenly sounded in the room: "Dear classmates, you can use this laboratory for a day, start the timer now, I wish you a happy alchemy!"

Robert no longer hesitated, strode into the room, and heard a soft thud as the door closed automatically.

I saw that this room was about twenty square meters square, and a magic circle was set up on the ceiling, emitting a soft light, and the surroundings were empty, only a large melting pot was placed in the middle.

Robert walked around the furnace, and saw that the furnace was about half a person high, and there was a large spoon for stirring in it, and a magic circle was set up under the furnace, and there was a small platform next to the magic circle, which was obviously used to put in the magic crystal ore that provided energy.

Robert sat down cross-legged, closed his eyes, and carefully recalled the alchemy knowledge he had learned in the library, and after a while, he felt that he had completely understood, and then slowly opened his eyes.

He took out the cracked goblin process diagram from the storage bag, leaned in front of him, looked at it carefully, and after a while, put the process diagram on his lap, held his chin in one hand, and fell into deep thought: "The production method of this smoking potion is only half translated, what should I do?"

After thinking for a long time, he was still at a loss, gritted his teeth, and said resolutely: "If you don't care about it, you will die!

Thinking of this, he immediately stood up, took out a low-grade fire type magic crystal ore from the storage bag, and put it on the small platform of the magic array, and suddenly the magic array lit up, rising a raging flame, enveloping the furnace, and the temperature in the room instantly increased.

Robert glanced at the process drawing, only to see the first material with the word "crystal ore" written on it, took a deep breath, took out a fist-sized piece of crystal ore, shook it, and threw it into the furnace with a clang.

Glancing at the process diagram again, he threw a palm-length thorn wood into the furnace......

Five or six materials were thrown in a row, and then half a barrel of mercury ore was added, almost filling most of the furnace, and then he stopped, looked at the last few untranslated goblin words, frowned, and said to himself: "This little material, it shouldn't be a big problem!"

Time passed slowly, drops of sweat ran down Robert's cheeks, and he was in a daze, unaware of the furnace and the magic circle.

After a while, the low-level fire magic crystal ore burned out, Robert snapped, snapped his fingers, and muttered: "The first step is complete, it's time to do the second part!"

After a while, Robert was taken aback by the sudden smell of sourness, and looked into the furnace, only to see that the materials had melted into a black liquid, and bubbles bubbled from time to time.

He nodded and muttered, "According to the description of the process diagram, this is what it looks like, and the following is the last step, how to operate it?"

He looked at the last small untranslated text of the process diagram, frowned slightly, showed a puzzled look on his face, pondered for a long time, and then said to himself: "According to the process diagram, the smoke-making potion will emit a lot of black smoke, and now the hair has not come out at all, is it because the firepower is not strong enough?"

After speaking, he took a deep breath, put the process diagram into the storage bag, and took out three low-level dark magic crystal ores, and put them all on the small platform.

The moment the magic crystal ore was placed, the magic array was full of light, and the black flames almost jumped to the ceiling, completely engulfing the furnace.

Robert took two steps back, wiped the sweat from his forehead, exhaled heavily, and shouted, "Now everyone is happy!"

Moments later, the furnace burned red, and the liquid inside bubbled one by one, making a crackling sound.

At the same time, a puff of black smoke emerged from the furnace and gradually filled the room, and the visibility of the room quickly decreased.

Under Robert's sword, he was suddenly overjoyed, put his left index finger in his mouth, "shh~~", whistled loudly, and laughed loudly: "I am really a genius, and I succeeded in the test at one time!

In the laughter, Robert inhaled a few puffs of black smoke, only felt sour and pungent, choked and coughed, snot and tears came out, did not dare to slack off, hurriedly took out more than a hundred empty medicine bottles from the storage bag, placed them on the ground, scooped out the black liquid in the furnace with a big spoon, and poured them into the medicine bottles one by one.

While Robert was filling the medicine bottle, the black smoke had already filled the entire room, and ignoring the surrounding formation seals, it drifted from the cracks in the doors and windows to the outside, gradually enveloping the entire teaching building.

Robert put the cap on the medicine bottle, put it into the storage bag, and said regretfully while coughing: "Ahem~~, buy less medicine bottles!Ahem~~, only waste ......"

He had just finished collecting the medicine bottle, and suddenly felt something falling to the ground, and couldn't help but be slightly stunned, leaned over to pick it up, only to see that it was a palm-sized piece of cloth, which had been tattered, and suddenly felt very familiar, and suddenly remembered: "Isn't this my school uniform?"

Hurriedly brought his left hand in front of him, only to see that the palm of one hand was as black as ink, but it was not hurt, but the school uniform worn outside was rapidly corroding at a speed visible to the naked eye

Seeing this strange scene, Robert almost spurted out a mouthful of old blood, and he was stunned for a moment, and said to himself, "What the hell! What kind of operation is this? Why are clothes corroded?"

In fact, with Robert's reaction speed, he should have already noticed this anomaly, but first, the room was too dark, and he didn't pay much attention to his clothes while he was excited, and second, the black smoke did not cause harm to his body, so it did not arouse his vigilance.

Just when he was stunned, the school uniform was already corroded, the belt was loosened, and his pants fell to the ground.

At this moment, I saw that the upper half of his body was wearing the leather armor of the Night Salute, but the lower half of his body was ......

Robert suddenly felt a chill under his crotch, reached out and touched his little brother, only to be frightened, knowing that he was going to suffer, and wanted to take down the magic crystal mine, but the room was pitch black, where could he see the location of the magic crystal mine?

In an instant, Robert's brain turned rapidly, and his heart said: "Thirty-six plans, go for the best plan!"

Thinking of this, he didn't dare to slack off, and immediately touched the storage bag, touched a pair of underwear, and put it on first, turned around and rushed out of the room.

As soon as he went out, he almost dropped his eyeballs, only to see that the black smoke was like hydrochloric acid, touching the yellow bricks and red tiles of the teaching building, only to hear the sound of sneering, these yellow bricks and red tiles began to be corroded, wisps of green smoke appeared, and the pits appeared one by one at a speed visible to the naked eye, and the color gradually dimmed, and finally turned black.

After a while, a glossy magical branch was unrecognizable, tattered, black, and crumbling, with fist-sized cracks in several places, and it looked even more dilapidated than the special admissions dormitory.

At this time, the teaching building was completely chaotic, and the students ran out of the laboratory and classroom coughing, one by one, their faces were dark, tears and snot flowed together, their clothes were torn, and they erupted in overwhelming cursing, especially those female students, who desperately covered their sensitive parts and screamed again and again.

"Ahem~~, what kind of smoke is this, ahem~~, it's so sour, it's choking me!"

"Ahem~~, what kind of smoke is this? I can't even stop it with a magic shield, ahem~~!"

"Ah~~, why did my clothes melt?cough~~!"

"Ahem~~, it's important to escape, what kind of clothes do you care?ahem~~, it's a big deal to be seen by a woman, and you don't suffer!"

"Ahem~~, I'm a man! It's okay if it's seen by a woman, but what if it's seen by a man and it makes them have a strong sense of inferiority?"

......

Under Robert's sword, he was so frightened that the cold hairs on his whole body stood up, knowing that it was going to happen, his brain turned quickly, and he hurriedly grabbed the hourglass on the door, ripped it off, and put it in the storage bag, so he wanted to stimulate the advanced stealth technique of the Night Salute, and then smeared oil on the soles of his feet and fled.

At this moment, the door of the nearby laboratory opened, and a young girl coughed and rushed out, hitting Robert at once.

Seeing that she had bumped into someone, the girl hurriedly grabbed two steps, helped Robert, and said apologetically while coughing: "Ahem~~, I'm sorry, ahem~~, I'm not ...... I'm not ......" Speaking of this, he suddenly recognized that the person in front of him was Robert, and couldn't help but widen his eyes and was stunned on the spot.
