The God of Ice and Fire at Hogwarts

Next, Green's guidance made Lynn feel as if she was back in the Potions class at Hogwarts Castle.

Of course, Green did not have the venomous tongue of Professor Snape, but patiently taught Linn all the formulas and brewing techniques of the blood fusion potion.

The blood fusion potion is much more difficult than the polyjuice potion, and the brewing cycle is also as long as two weeks, which is half a month.

Therefore, Green ended the day's teaching after guiding Linn to handle all the potion materials in the correct way, add them to the crucible in the correct proportions, and light the alcohol lamp.

The preparation of the blood fusion potion lasts for half a month. The most difficult parts are at the beginning and when it is about to be completed. In the middle part of the preparation, Linn only needs to add the blood fusion potion every other day. Just add the specified materials without having to sit next to the crucible.

So Green kicked Lynn out of his room, and before that, Green did something that Lynn was very familiar with.

That is to throw a thick book recording the magic of blood fusion to Lin En and ask Lin En to complete the self-study within five days.

Lin En looked at the bloodline fusion magic book that was nearly a foot thick in his hand, and the corners of his mouth twitched crazily.

This is really Green's consistent style!

The familiar feeling is back!

It only took one morning for Green to explain to Linn the basic theory of blood fusion magic and the method of brewing the blood fusion potion. This also meant that Linn could study this book in his room in the afternoon and evening. .

After seeing off Linn, Green enjoyed a leisurely lunch, and then went to instruct Fred and George in their alchemy.

Unlike Linn who used alchemy to refine various functional alchemical creations, Fred and George's main focus was to apply alchemy to combat.

Therefore, Green could not throw thick alchemy books to the Weasley twins and let them learn on their own like he taught Linn. Instead, he had to give them guidance at all times.

After all, unlike refining alchemical creations, the battlefield is ever-changing, and the techniques for applying alchemy to actual combat are also ever-changing.

Time passed day by day, and in a blink of an eye, the day came when the blood fusion potion was completed.

In this half month, Lin En thoroughly understood the theoretical knowledge of blood fusion magic, and in the process of brewing the blood fusion potion in this month, Lin En also completely mastered the method of brewing the blood fusion potion.

At this time, in Green's room.

Lin En stared at the blood fusion potion in the crucible. After half a month of brewing, the potion in the crucible was as transparent as water, crystal clear to the bottom.

But when Linn used his wand to stir the potion in the crucible, he found that the potion in the crucible was very viscous, like a coupling agent.

"The next step is the last step, Linn, add the essence and blood of the magical animal you want to fuse into it. Just add three to five drops."

Green said.

Linn nodded slightly and looked at the dozen bottles of scarlet blood on the table. These were the blood essences of different magical animals, including fire dragons, giants, goblins, sniffers, thunderbirds, etc.

Lin hesitated for a moment, and finally chose to open a bottle containing the blood essence of the black dragon of the Heshidry Islands, place it above the crucible, tap it three times, and drop three drops of the fire dragon's blood essence into the crucible.

The moment the essence and blood filled with magic power submerged into the potion, the originally transparent potion suddenly turned into a scarlet color.

The essence and blood that had originally become a bit turbid and dull in color due to being stored for too long, after being blended into the blood fusion potion, actually turned the entire pot of potion into bright red!

"Turn the alcohol lamp to maximum, use the wand to stir the potion clockwise three and one-half times, and then stir it counterclockwise twice."

Green directed.

Lynn did so.

I saw that the originally calm potion suddenly boiled, and many small bubbles floated from the bright red potion and exploded on the surface of the potion.

This process lasted for nearly half an hour before Green asked Linn to turn off the alcohol lamp.

After half an hour of boiling, the bright red potion turned dark red again, but unlike the original turbid dark red, the potion now looked extremely clear.

Seeing the appearance of the blood fusion potion, Green nodded with satisfaction and said: "Perfect, let's integrate the blood fusion formation into the potion."

Linn nodded. As he waved his wand, countless fine golden threads surrounded the crucible, constantly intertwining.

Alchemy formations were condensed in the sky above the blood fusion potion, and were combined according to fixed positions to form an extremely complex formation.

In the field of alchemy, those who can connect countless alchemy formations together, and are called formations, are all very advanced beings.

Before coming into contact with this bloodline fusion formation, the only two formations that Lin En mastered were the time stasis formation and the time cycle formation, which were extremely powerful.

At this time, under Lin En's control, the bloodline fusion formation slowly fell into the crucible.

At the moment when the alchemy formation and the blood fusion potion were fused, violent magic fluctuations spread, and Lin En seemed to hear the roar of the black dragon of the Heshidry Islands.

But in the next moment, the surging magic power and the vague roar of the dragon disappeared, as if what Lin En had just felt was an illusion.

All the power was gathered together and concentrated in this dark red potion.

Then, the potion in the crucible began to shrink on its own, as if the excess water had been evaporated. The originally full pot of potion ended up with only a small bottle left.

Linn put the blood fusion potion in the crucible into a one-ounce narrow-mouth bottle, just enough to fill it up.

Lin En held the blood fusion potion in front of his eyes and asked curiously: "Is this the blood fusion potion of the Black Dragon of the Heshidry Islands?"

Lin En could feel that this small potion contained extremely powerful power, which was enough to destroy a house in an instant.

Green nodded slightly and said with a chuckle: "Yes, I didn't expect you to choose the essence and blood of the black dragon of the Hesidian Islands. In fact, the blood fusion potion made from the essence and blood of the black dragon of the Hesidian Islands is basically Only quasi-demon-level wizards, or even demon-level wizards, are qualified to take it."

Linn was not surprised. According to the rigid requirements of bloodline fusion, the wizard who merged the bloodline must have the ability to crush the magical animal with the fused bloodline.

If you want to crush the black dragon of the Hesidian Islands, the wizard must have a quasi-demon-level magic level, right? !

After all, even though Linn crushed the Hungarian Horntail in the first event of the Triwizard Tournament, he still relied on his own affinity for flames.

And wasn't Lin En a quasi-demon-level wizard at that time? ! (End of chapter)
