"Too disgusting."

"Ah, I want to look away. Can I?"

"Don't you idiot; you might miss something important."

There were so many impurities that once they got together, they made a small worm.

Although it was too small, everyone could see it and got disgusted when they saw the worm made of impurities wriggling about on the table.

"Sir, are these impurities?" One of them asked.

Alex nodded his head and said, "The ingredients I used were of the lowest grade. Thus they were full of impurities. Usually, alchemists don't use them. Anyway, I used it to show you guys what an excess of impurities looks like to make you better understand how important it is to get rid of as many impurities as you can before beginning the pill creation process. Consider this black, ugly-looking worm wriggling inside of you, moving from your guts to your heart, aiming to nibble on it. Would you like that?"

"I definitely wouldn't."

"I would be too disgusted with knowing that something is inside of me, and I'm living with it."

"I might stab myself, hoping to kill it."

"Oh, I can't, I can't help it anymore!" One of them stood up, rushed to the dustbin, dropped down, and puked out of disgust. Vincent could tell from a single look that this weird-looking kid with spiky yellow hair must have imagined it happening to him, and that's why he couldn't get help but throw up.

"Ahem!" Instructor Alex continued his lesson, almost acting as if he didn't notice that someone puked up because of his exact words, "Everyone, take a few sets of ingredients needed to create the energy restoration pill from the drawers on your left and start purifying them. If you manage to get rid of 50% impurities from all of the four ingredients, I will consider it as you having enough talent to start learning alchemy. If not, you guys will keep on purifying the ingredients until you get it right."

He had not said those words when a small hovering robot with a round body entered the classroom.

"Mr. Holmes will be overseeing your process. Don't try to cheat. And yeah, half of the class must succeed, or else I won't be teaching the pill creation process! Compassion and bootlicking the talented ones for their wisdom is the key here, don't forget that."

After throwing those somewhat taunting words, instructor Alex stepped towards the door.

"Sir, where are you going?" Eric asked while looking at his back.

"To the classroom on the left." He said without turning around to look back at him and left the room quietly.

The classroom on the left was more like a club. It had a sofa bed, and he came here to rest and relax his taut muscles and veins.

He laid down on the sofa, out on his blindfolds, and fell asleep immediately. The sound of snoring echoed in the club room disguised as a classroom.

Talk about being irresponsible; he definitely was on top of the list.

However, the students couldn't do anything as he had already handed out a task to them, and they had to complete it before they could have him teach them any further about alchemy.

Everyone got busy with testing how good they were at purifying ingredients.

Vincent, too, was among them. He always had self-studied, so such a collective environment was new to him.

He preferred doing everything alone. So, he picked up a tray, pulled out the four herbs shown to him by Alex, put them on the iron tray, and returned to his table.

Vincent was the only one there, and he felt that it was good that he was alone.

He put the tray on the table and got to work.

[Ingredient 1 Impurities: 4 units]

Ingredient 1 Impurities: 3 units]

[Ingredient 1 Impurities: 8 units]

[Ingredient 1 Impurities: 5 units]

Each of the herbs had a different amount of impurities in it.

However, the ingredients Vincent picked up carefully had a hundred to thousand times fewer impurities than the ingredients instructor Alex used to demonstrate the process.

"A total of twenty impurities means that it will only take me 20 units of mana to purify them. Good enough."

Vincent got to work. Now, he had two ways of purifying the herbs.

Vincent could use the spell matrix filtration to get rid of the impurities in the herb.

As it was something special, he was sure it would be too easy to purify herbs using it.

But where was he? He was in a public place.

He couldn't possibly use his spell matrix here as there was a chance someone might notice it or become suspicious that he got some kind of treasure that let him purify stuff.

Even though there was only a sliver of a chance of that happening, Vincent didn't want to take a risk.

Vincent took the better road that would keep his secrets safe. He performed the hand signs necessary to gain control of his mana. He wasn't instructor Alex, who did not need to perform hand signs to control his energy as he had an energy circuit. Vincent lacked one, and thus, he could only use hand signs to move his energy.

The few people who were interested in him saw mana surging out of his palms in the shape of thin threads, a total of twenty, which injected themselves into the four herbs.

[Ding! Spell Matrix Filtration self-activated itself.]

The moment his energy threads entered the ingredients, a notification telling him that his spell matrix had activated to help him popped up in his mind. Vincent just heard those words when in the very next moment, he gained another field of vision.

In this field of vision, he was able to see white dots, black dots, blue lines, and many other colorful lines.

A thoughtful look flashed across Vincent's squinted eyes as he assessed the situation.

The colorful lines and the white dots were the medicinal essences of the ingredients!

The blue lines were his mana threads!

The black dots were the impurities!
