Principal Dippet is a clear-cut person in Zhao Mai's impression: he only shows kindness to his students and respectable wizards, and does not care about anything else. To a certain extent, Dumbledore is a new version that makes Principal Dippet more fraternal, and the two of them can become principals of Hogwarts one after another. In addition to their extensive connections and similar personalities, they must have convincing abilities in magic.

"As a matter of fact, I can't underestimate anyone." Zhao Mai took the manuscript with a little wrinkled edge, and his hands were trembling a little. He opened the hard cover, and the first page read Principal Dippet's gift. I only found the right words in the wisdom of the East: It's not too late to make up for the dead.

"There are two parts of the memory resurrection spell. One is the resurrection spell used by a single person, and the protection period is extended to three months. Since new memories will continue to occur, if you cast the Forgetful Spell for more than three months, it will be too dangerous, and it is easy to turn people crazy or stupid. Even after simplification, the difficulty of this spell is not low. Only a few mages have enough magic control to cast it. Principal Dippet conducted an experiment on himself, and I will cast this spell to prove that it is indeed effective."

Zhao Mai jumped up from his seat: "What, you guys do experiments on yourself, how can this be done!"

Dumbledore waved his hand and signaled Zhao Mai to be calm: "It's not a big deal. I wrote a string of numbers for the principal to remember, then washed away his memory, and then recovered it. After many experiments, we only conducted a complete memory removal and found that the spell was still very effective. We are actually very willing to do this experiment, after all, we also want to know how to overcome the effect of the forgetting spell."

"I don't know what else I can say except thank you."

"We were going to try to study spells. The results were not for your gratitude, but unfortunately we couldn't publish them..." Dumbledore continued: "The second part of the notes is about large-scale memory recovery. We studied the model of that spell and deduced it many times, but we have not tried it successfully. The magic required by the spell is too strong, exceeding our casting ability. We hope that one day you have enough ability to cast it and then tell us the result."

"I will work hard." Zhao Mai ignored the politeness and impoliteness, and read the manuscript eagerly, imprinting every word on it in his mind. Dumbledore saw Zhao Mai so serious and studious, smiling with relief, and did not urge him, but just drank tea and snacks quietly. For a moment, there was only Zhao Mai's slight reading sound and the rustling sound of flipping the pages in the room.

When using the supernatural powers to assist, Zhao Mai's memory is terrible. He once passed the exam for grade 1 to 7 in this way. It took about twenty minutes and he completed the reading from beginning to end. He closed his eyes and recalled several times, and then used twenty minutes to remember it again. When he came to his senses, he found that Dumbledore, Serena, Dogian and Xiaohua were playing poker. Sardili had five notes on his face and was refereeing to avoid anyone using magic to cheat.

Serena's face was the cleanest. Dogian and Xiaohua were both two notes. Dumbledore mixed four notes and her beard together, and basically couldn't tell. He saw that Zhao Mai had already received the notes into his portable space and threw the card in his hand: "Ahh, Mike has recovered his spirit!"

The 17,000-year-old demon Serena snorted: "Cunning little devil..." and then put down the poker. Xiaohua held her breath hard, and her hair suddenly turned red, and she burned the note, and her face was still as round as white jade.

"Thank you for waiting for me. I'm stupid. I just confirmed that I remember this spell." Zhao Mai said hurriedly.

"I know how you passed the exam now. It's such a terrible memory." Dumbledore said with a smile: "How about you, do you think you can release the group memory resurrection mantra?"

"I'll try." Zhao Mai took out his wand, began to concentrate his magic power, and slowly recited the spell. His domain opened up to assist him in casting this magic. But his wand quickly began to shake. The too concentrated magic power had reached its limit. Continuing to advance the spell would only damage the wand.

He had to stop the spell. Dumbledore nodded: "The title of Lord is indeed not for free. Your magical power is indeed incredibly powerful. You have also seen the entire spell and know that it cannot be cast from the wand. So your most urgent task is to find a wand that can withstand your magic power."

"I have it." Zhao Mai took out the elder brother wand. This time it was Dumbledore's turn to jump out of his seat. For the first time, Zhao Mai saw his eyes so big, looking at the wand in his hand round.

"I'm right, is this one of the legendary three holy weapons, the old wand?"

"Yes, that's the one. It is said that it can withstand unlimited amount of magic energy, and in the past there was no magic spell that could reach the level of magic consumption of group memory resurrection, so you can try it."

Dumbledore rubbed his hands and stroked his beard excitedly: "I'll wait and see!"

Zhao Mai pushed the spell again, his whole body shone brightly, and the blue flames rose up, giving people the feeling of wanting to worship him. A large amount of magic power was mobilized from all directions, and even affected the magic circle of Lemay Manor, making their house tremble constantly, as if it was attacked. Nick Lemai hurriedly called Barbara, "Hurry up, turn off the magic defense, otherwise the house will collapse again!"

The word "re" expresses all the bitterness, but Zhao Mai didn't hear it, nor did he know what happened to his neighbor's house. He kept pushing forward the spell, and the old wand actually trembled. The black elderberry was shrouded in a ball of white light, and then a crisp sound came.

The magic power that had lost control wanted to flow around, but was locked tightly by Zhao Mai using domain and mental powers, and then slowly released it to avoid damaging the surrounding environment. The old wand cracked from the root to the top, and even repairing the spell could not improve the crack at all.

Dumbledore shook his head and said with some disappointment: "Three possibilities: this spell is theoretically unfeasible; the old wand is not able to withstand infinite magic power as legendary; the old wand is a copy."

"It should be imitation, you can feel it by pushing it to the limit." Zhao Mai said deliberately. After time backtracking, he knew that there was a high imitation Grindelwald on the earth, and there was an old wand in his hand, and Dumbledore was likely to meet him in the future. Zhao Mai did not want Dumbledore to underestimate the power of the old wand, or mistakenly used the old wand as a trick to reduce his vigilance, so he said that the one in his hand was imitated.

But the real reason is that the elderberry wand only has superiors, no relatives, and no feeling of blood connection. This astringency will hurt the wand when the magic power reaches its peak, causing it to break. But this is also good, which strengthens Zhao Mai's determination to use the power of elderberry to enhance his wand.
