Harry Potter: This senior is pretty strong

"Professor Swinton, you are indeed a learned and super genius. You have cracked the formula for this alchemical material in such a short time. As your student, I am very proud!" Qin Yu said seriously.

"Haha, that's an exaggeration, that's an exaggeration. I'm still far from being as good as my teacher, Mr. Lemaître. This little thing is nothing to mention!" Professor Swinton said with a rather self-satisfied wave of his hand.

Of course, the upturned corners of his mouth showed that he was very happy.

If it were Professor Snape, after hearing Qin Yu's words, he would have rolled his eyes at him and coldly said, "Instead of wasting your time flattering me, you should review the spells I taught you."

Professor Swinton, on the other hand, was more thick-skinned—or rather, more nonchalant.

Recently, Qin Yu has been following Professor Swinton to learn the theoretical knowledge of alchemy and to do some simple alchemical operations, such as the common alchemical processes of blackening, yellowing, and whitening, as well as how to obtain pure cinnabar, and so on.

Professor Swinton, while teaching Qin Yu, devoted almost all his remaining energy to the reverse engineering of the alchemical materials used in the small pyramid. As a result, he even became somewhat distracted in his Defense Against the Dark Arts class. The students hadn't been frightened by those disgusting images for a long time, and their appetites had improved considerably.

Now, after many days of research, Professor Swinton has finally figured out the composition of this material, which really took a lot of effort.

"Alright, Qin, stop standing there, let's get started. I can't wait," Professor Swinton said to Qin Yu, rubbing his hands together and his eyes shining.

"..." Qin Yu.

Although Qin Yu understood Professor Swinton's passion for alchemy, he felt that his words and expression made him want to turn around and leave immediately.

Professor Swinton had no idea what Qin Yu was thinking. Without saying a word, he handed Qin Yu a set of alchemist's robes from the room, and then waved his wand to put on the same clothes himself.

This is a long robe with an antique pattern.

After Qin Yu put it on, he and Professor Swinton went to the alchemical materials and tools.

"Let me test you. What is alchemy?" Professor Swinton asked solemnly before officially beginning.

"Alchemy is the manipulation and exploration of the four elements: earth, wind, water, and fire. It is the use of these elements to create more noble substances, and even life!" Qin Yu stated the definition of alchemy.

“That’s right. Nobility comes from tempering and forging. The four most primordial elements in the world are reborn from fire and all kinds of hardships,” Professor Swinton said with a devout expression.

After saying this, Professor Swinton directed Qin Yu to begin some preparatory work, including preprocessing the necessary materials.

Qin Yu had done these preprocessing operations many times before, so they were not difficult to perform.

By the time Qin Yu finished processing the materials, Professor Swinton had already set up the alchemical cauldron, with blue flames burning beneath it.

Next, Professor Swinton instructed Qin Yu to place the pre-treated materials into the alchemical cauldron one by one in order, while he himself waved his wand to control the intensity of the flames and the flow of matter within the cauldron.

As Qin Yu placed the last ingredient into the alchemy cauldron, the substance inside transformed into a mixed-color liquid.

At this moment, Professor Swinton cast a spell that suddenly increased the temperature of the flames. Then, he carefully took out a transparent glass bottle containing white powder from his pocket. He then opened the cork of the glass bottle and poured about one-third of the white powder into the alchemical cauldron.

"This is an alchemical catalyst given to me by His Excellency Lemaître, which can save me a lot of troublesome steps," Professor Swinton explained to Qin Yu, who was somewhat puzzled.

Upon hearing this, Qin Yu nodded, his eyes continuing to observe the reaction within the alchemy cauldron.

As the white powder was poured in, the originally chaotic molten liquid underwent a violent reaction, as if it had come to life, beginning to intertwine and merge. The liquid's color gradually became uniform, until—

It turned golden yellow!

Golden yellow, that's the color of gold.

Of course, Qin Yu knew that what they were refining was not gold, but a substance even more precious than gold.

Professor Swinton, who was constantly watching the changes in the alchemical cauldron, waited until the liquid color met his requirements. Then, he waved his wand and gradually reduced the flames under the cauldron until they went out. The whole process was very careful; he dared not be too fast or too slow.

After the flames were completely extinguished, Professor Swinton cast a levitation spell on the pool of golden liquid, which then rose from the cauldron and transformed into a round, golden sphere the size of a Quake ball.

As the sphere rotates in the air, it gradually changes from a liquid to a solid, leaving shallow, cloud-like patterns on its surface.

"Qin, catch!" Professor Swinton shouted, raising his voice.

Upon hearing this, Qin Yu quickly stretched out his hands.

The golden sphere, under Professor Swinton's control, slowly descended and finally landed in Qin Yu's hand.

The moment his hands touched the sphere, Qin Yu seemed to feel the life force emanating from it.

Alchemy is indeed a magical discipline.

Qin Yu thought to himself.

……

The successful refining of the alchemical material was the first step in the construction of the pyramids. They would use this newly created alchemical material to forge the five faces of the pyramids.

Next, the spells on the smaller pyramids were replicated on the five faces of the main pyramid.

"This is a very ancient spell, which uses some ancient incantations. Your friend is quite talented to be able to carve these incantations into the pyramid," Professor Swinton said to Qin Yu.

“Yes, Bill is really amazing. I can’t even imitate those incantations,” Qin Yu nodded and said.

“Haha, drawing incantations isn’t just about copying the image; you also need to sense the flow of the incantation. Otherwise, even if you draw it exactly as it is, it won’t have any effect,” Professor Swinton said with a smile.

“That sounds a bit troublesome,” Qin Yu said with a shrug.

"Yes, it is said that these incantations were drawn by ancient wizards who sensed the voices in the dark. Of course, we don't need to copy them like they did. We just need to be able to imitate the general idea... I'm afraid I can't handle this by myself. I need to find someone to help me."

The first person Professor Swinton could think of was Professor Dumbledore, of course, but he immediately dismissed the idea because he didn't want to waste Dumbledore's energy on such a trivial matter.

Then, Professor Snape became the best choice besides Professor Dumbledore.

Qin Yu couldn't offer any help with this matter, so he left it to Professors Swinton and Snape to investigate.

……

Five days later, in the evening, Qin Yu was summoned to Professor Swinton's office.

In the middle of that office stood a golden pyramid, more than a meter tall.

Professor Swinton and Professor Snape, one with a smile and the other with a cold expression, stood like sphinxes on either side of the pyramid.
