Snape still didn't return Lily's picture to Calvin after all. But this was also expected by Calvin.

Calvin smiled strangely at Snape, much to Snape's annoyance, but didn't say anything more.

Leaving Snape, Calvin continued to instruct the students in normative contact with the Moon. However, it wasn't until the end of the class that only the Weasley twins' group had recorded the Moon Idiot's strange dance in its entirety - they cheated, videotaped it with a crystal ball, and replayed it over and over again before drawing the dance entirely on parchment.

"Gryffindor, Hufflepuff plus ten."

"It's not fair, they're cheating." Cassius Warrington of Slytherin shouted.

"I'm not forbidding you to use extra items to complete your mission." Calvin said calmly.

Fred looked quite proud: "I asked you to buy our crystal ball a long time ago, how about it, now you know how powerful it is." ”

"Homework to draw the dance of the Moon Idiot on parchment in its entirety, and write a paper on the structure and characteristics of the Moon Idiot's magic, no less than six inches."

For the next few days, Calvin traveled between Hogwarts and the reserve, leading the fourth-year students to encounter birds and snakes in the Shuofeng Meadows, and the fifth-year students to learn horse-shaped water monsters on a boat in the Abyssal Trench. Lead senior students to watch the life of the fire dragon from afar on the outskirts of the lava mountains.

Finally, the first practical class of all grades was over, and Calvin had a chance to study Voldemort's soul.

Over the weekend, Calvin went to Bascinda's gloomy basement again, and when he opened the door and entered, he saw a white-haired, long-legged witch sleeping on the couch in a thin wizard's robe, with her legs resting irregularly on the coffee table.

Calvin glanced at it and said "I'm sorry" before exiting the room. Inside, Bassida was also awakened, and quickly re-clocked the door to invite Calvin in.

Calvin said a little embarrassed, "I'm sorry I thought you told me to come in directly, so I didn't knock on the door." ”

Bassida waved her hand and yawned, "It's okay, I've been studying your mirror for the past few days and haven't replenished my nutrition in time." ”

Calvin secretly said in his heart, "What kind of nutrition, I'm afraid it's less blood and drink." ”

Calvin skipped this awkward topic and asked directly, "What about mirrors?" ”

Bassida returned to her desk, pulled open the drawer, and carefully removed the mirror.

"Everything is intact."

Calvin put on a dragonskin glove and flipped the mirror over and over several times, "Is there a way to make up for the final 'acceptance' of the magic text." ”

Bassida shook her head, "There's no way, now the core pattern in this alchemy item and Voldemort's soul form a strange balance, and the slightest change will cause it to collapse directly." ”

"Why did you take a half-finished product and go up in the first place...... Even if it's half an hour late. Speaking of which, why did you design the core part of this item so complicated, this is completely not in line with your alchemist level. ”

Calvin sighed, "The situation is urgent, if I go any later, those three students will be in danger." As for the complex core texture, I designed it on purpose, and it has other uses. In fact, I am very satisfied with the results so far. How long do you estimate this mirror will last? ”

"By September of this year." Bassida said helplessly.

"Then you are more optimistic than me, I guess by July of this year." Calvin placed the mirror in the crystal bottle and prepared to take it away, but Bascida stared greedily at the mirror.

"Can I keep it for two more days?" Bascinda stared at the mirror and said to Calvin.

Calvin sensed something was wrong and looked warily at the white-haired witch opposite.

"Can you please not take it away......"

Calvin didn't talk nonsense, and a rope flew out of the tip of his wand to tie Bascida to the chair, and then took out an hourglass with white sand from inside his clothes, took it off and put it around Bassida's neck.

"Capet, what are you doing?" Bassida finally came to her senses and yelled as she took control of the ubiquitous Demonic Script in her office and prepared to fight back.

"Professor Barbling, I beg your understanding, you are in danger right now." Calvin casually repelled a few demons with no small attack power, his eyes fixed on the hourglass hanging from Bascida's flat chest.

Sure enough, the white sand at the bottom of the hourglass gradually turned black and spread until a third of the way to the end before stopping.

Bassida was also taken aback by Calvin's serious expression and asked, "What is this?" ”

Calvin plucked the hourglass from Bascida's neck, "This is an alchemical item that detects whether a wizard's mind has been corrupted by dark magic, and it was made by Nicol Lemay. It's bad that you've been eating away at black magic for the past few days. ”

"It's the mirror, no, Merlin's beard, it's Voldemort's soul!" Bascinda woke up suddenly, "Damn, I was careless. ”

Calvin nodded, and let go of the rope for Bassida, "It seems that Tom is not willing to be lonely even if he is locked in the mirror." ”

Bascinda moved her arm, which was tightened by the rope, and looked at the mirror with fear, "Otherwise, this mirror should be given to Albus, I think it's too dangerous." ”

"No, I'll just keep it, your experience has reminded me." Calvin took out a turquoise pendant from his sleeve and placed it on Bascida's table, "Here's for you." ”

"What is this?" Bassida was a little puzzled.

"Uh," Calvin thought for a moment and organized his words, "it's an alchemical item from the Far East, it can help you get rid of the erosion of the mind of black magic, just wear it around your neck." ”

Basida was silent for a moment, then smiled, "It's been a long time since anyone gave me something like this, thank you." ”

Calvin waved his hand to show no thanks, "Then I'll go first." ”

Basida looked at Calvin's distant figure, propped her hands on the table, smiled weirdly, licked her lips with her tongue, and whispered, "Interesting, this person's blood must be delicious." ”

Calvin returned to the office, used seven or eight defensive spells to protect the office, and then used the brain defense technique all the time, and then took out the silver mirror made from the remains of the crown from the crystal bottle.

Calvin flipped the silver mirror to the back, which was carved with various intricate core patterns. Calvin rotated the mirror at an angle, and these intricate patterns became a delicate and small painting.

"Voldemort, I have to talk to you." Calvin muttered to himself, and then a flash of white light flashed, and Calvin entered this special world of painting.
