"Heated?" Jon replied without thinking, "The treated Ash Snake's eggs are mixed with Motra's tumor, not to be slowly heated until the eggshell becomes soft, and then the eggshell is crushed......"

"You can't see an open flame!" Horace-Slughorn almost roared, "This is the egg of the Fire Grey Serpent, which itself is extremely sensitive to phlogiston...... In addition, after being treated with the Gublai Immortal Fire, just a little spark can make it fall into a completely burning state...... Merlin's beard, the egg of a completely burning fiery serpent, releasing enough heat to burn my castle ten times!"

"I'm sorry!I'm sorry!" Jon quickly apologized, then pulled out his wand to extinguish the cauldron's flames.

He knew all too well the energy contained in the Grey Snake's egg, after all, he had used it himself.

Slughorn, who was in a state of agitation, slowed down for a few minutes before he barely calmed down.

"Such a low-level mistake......" he turned and looked at Jon with a skeptical look, "Are you supposed to ...... Unprepared...... It's the first time you've made a magic potion, right?"

"This ...... You've guessed it!" Jon looked down in shame, and then he quickly added, "Of course, I'm very familiar with the specific steps and sequences. ”

The look on Slughorn's face made him look like he was about to faint...... If it weren't for the existence of that unbreakable oath, he would definitely drive the stinky boy in front of him away now, and the farther away the better......

The first few steps of the preparation process of the elixir can be said to be very dangerous...... The slightest mistake can cause a fire and turn a radius of hundreds of meters into a scorched earth, and when Slughorn first prepared the Elixir thirty years ago, he had tried hundreds of times in advance and memorized all the steps before daring to make his first real attempt...... And in the next thirty years, he only dared to configure it seven times in total.

I didn't expect this stunned young man in front of me, actually-

Once there is a point accident...... As a wizard, Slughorn himself naturally has no problems with safety, but the castle does not know magic, and if the castle is burned to the ground, how can he apologize to the ancestors of the Slughorn family!

"It's okay, I swear...... There won't be such a low-level mistake!" Jon swore on the side.

"Don't worry, Professor Slughorn!" Mrs. Greengrass, who was on the side, also said something that seemed to be comforting but not like comforting: "If anything happens, I will protect you in time...... Don't let you be in danger!"

Slughorn took a deep breath, and then sighed, he couldn't help it......

Because of the existence of the unbreakable oath, if he stopped the boy next to him from continuing to prepare, then it would mean that he had broken the oath, and the impact would be even more serious than losing the game.

On the one hand, he has to keep the game going until one side loses and the game is over, and on the other hand, he has to stop the boy in front of him from making some low-level mistakes that lead to the destruction of Slughorn Manor......

He just feels tired now!

......

"You have to use a lead rod to grind the eggshell, otherwise the slightest spark will be over!"

"Take care of the temperature control when bathing...... Be sure to pay attention to temperature control......"

"Hurry up and add a piece of the vine of the devil's net into it to stop the spread of phlogiston, otherwise something will happen!"

Horace-Slughorn's screams rang out from time to time from inside the room.

Apparently, he had stopped Jon from trying to burn his entire castle to ashes time and time again.

Jon's movements were very slow, and for him, the first mistake was indeed caused by his own unskill, and the many subsequent "mistakes" were clearly deliberate...... Grabbing Slughorn's attention forced him to spend time "helping himself", thus distracting him from devoting himself to his own potion.

There's no way, the skills are not as good as others...... can only use this slightly "inferior" method to narrow the gap between the two.

Due to the extreme caution with which the operation was always performed, coupled with the "help" of Slughorn on the side...... Step by step, Jon was able to clear the customs smoothly.

Almost six hours later—

Over the past six hours, Jon has finished grinding the eggshells of the Grey Snake eggs, the water bath is warm to fuse the eggshells with the solution, and then the vines of the Devil's Web are added little by little, neutralizing the phlogiston...... Finally, when Jon added a small spoonful of finely powdered sugar, the solution in the crucible was completely calm, turning into a clear liquid.

Slughorn on the side couldn't help but breathe a sigh of relief.

Once this step is complete, the solution is completely stabilized...... The castle is no longer in danger of being blown up.

......

"You're a great little guy indeed!" Slughorn couldn't help but comment, "I was able to do this on my first try, and I'm afraid I was ashamed of myself back then." ”

As he spoke, he lowered his head, focusing on his own crucible.

Slughorn had already done this an hour earlier, but with a large portion of Jon distracted from his energy, Slughorn's recipe was much worse than what he had made on several occasions.

But even so, it was much better than the solution that had just been made in Jon's crucible.

"Thank you!" Jon nodded solemnly.

"Do you need a break?" Slughorn asked with a smile, and in his opinion, the winner was decided.

"No need. Jon said calmly, "Let's go on!"

Next, due to the different potions sequences in their control, the preparation steps of the two people will not be the same......

Slughorn first removed a bottle of thyme tincture from the shelf, then three drops into the clarified potion in his crucible, and Jon rummaged between the shelves, but he took off a bottle of thymol, which he only dropped into the clarified potion and added a little powdered sugar......

Slughorn watched his movements and couldn't help frowning slightly.

"Are you related to the late former Headmaster of Hogwarts, Armando Duppert?" he asked softly.

Principal Dippert...... Uh......" Jon replied vaguely, "A little...... My aunt and him...... What the ...... is that?"

"Oh, shit!" Slughorn's face became solemn for the first time, and a sense of crisis appeared: "You actually used Principal Dippet's elixir sequence......"

He walked to the herb rack and began to quickly select the herbs he needed.
