Hogwarts: Don’t panic, Old Deng, I won’t be the Dark Lord

"The Animagus is..." Professor McGonagall kept explaining the knowledge points on the stage, while Draco was sitting in his seat and shaking his body restlessly.

Finally, as a bell rang, Professor McGonagall said get out of class was over and left the classroom.

Sisley stood up and stretched hard, and turned around to continue torturing Draco, but Draco had already opened the window and looked at Sisley with a wary expression.

"Huh? You don't want to live anymore, you want Uncle Malfoy and the others to open a small account." Sisley raised his eyebrows and slowly approached.

Draco's operation at the next moment was really unexpected by Sisley. He jumped down without any hesitation. Before everyone could react, Draco jumped down like this.

Sisley quickly lay down on the window sill but heard a curse, and Draco slowly fell to the ground without any harm.

"This kid is quite lively." Sisley raised his eyebrows and sighed.

"Don't worry, we should go to class!" Hermione held Sisley's hand and walked to the empty corridor and whispered.

"There's no rush... I'm too sleepy. Let's go back to the dormitory to catch up on some sleep." Sisley yawned as he spoke.

"Is this...ok? Can it be used like this?" Hermione asked doubtfully.

"Otherwise, why do you think this thing can be returned for twenty-four hours? If it can only be used for class, returning it for one and a half hours is enough." Sisley said, pushing Hermione's back, and the two of them moved toward the grid. Go to Llanffindor Tower.

Sisley slept for a full three hours this time. If Xiao Qi hadn't woken him up because he couldn't stand it anymore, he would have slept until the next morning.

"I didn't expect you to be quite considerate." Sisley sighed as he rubbed his swollen head.

"Of course!" Xiao Qi said coaxingly.

After Sisley walked out of the boys' dormitory, he saw Hermione holding a book and reading while waiting for him.

"Let's go, what's this lesson?" Sisley said, patting Hermione's shoulder lightly.

Hermione put the book away and said: "Number Divination, I hope it won't be as bad as the Divination class." Hermione sighed.

The two just chatted for a while, and finally found an abandoned and empty classroom specially arranged for them by Professor McGonagall, where no one usually showed up.

After taking out the time converter and moving the time forward for four hours, the surrounding scenes began to collapse and reorganize rapidly, and then returned to their original state in the blink of an eye.

The two looked at each other and walked towards the number divination classroom.

The number divination classroom is very normal, with a podium, desk, blackboard, and desks all available.

The professor is a middle-aged wizard who is energetic, muscular, with neatly trimmed hair and beard, and wears rimless glasses.

"My name is Amien Dachikos, you should call me Professor Dachikos." Professor Dachikos said slowly after watching the little wizards all arrive.

"Numerical divination, also called mathematical divination, and astrology divination, crystal divination are known as the three major divination sciences... Some of our classmates may have taken a class, or they may have studied Professor Trelawney's divination class before. I can only Say... every other line is like a mountain."

"Professor Trelawney is a half-assed seer, not a fortune teller. She can only use her talent to see fragments of the future intermittently, while we use beautiful numbers and rigorous logic to infer the future. , control the future.”

"Now, I will put the next number on the blackboard. You can use association and logic to calculate how old I am." As he said, Professor Dachikos wrote an Arabic numeral 7 on the blackboard.

"Use any calculation method you know to concoct this number. A little tip, if you are wondering why there is only one number... you can also find the second number on your own, just find it."

"The charm of mathematical divination is this excellent adaptability. Give it a try." After finishing speaking, Professor Dachikos stood aside and waited quietly.

Sisley casually took out a quill pen and wrote the number seven on the parchment, and then looked at Professor Dachikos's wizard robe, which was as black as ink and had silver buttons, seven in total, and he buttoned them up. Three.

"Look for other numbers yourself..." Sisley muttered, writing 7x (7-3) = 28 on the parchment.

"Twenty-eight years old? Too young...Look..." Sisley smacked his lips and continued to look at the blackboard...

"Blackboard? Four corners?" Sisley muttered in confusion.

"Is it possible? Try it!" Then he continued to write 28x4=112 on the parchment...

"112? Too old. Although the beauty magic is not ruled out but...yawn..." Sisley yawned again.

Sisley looked at the number 7 on the blackboard again. If you take apart the turning points... one is horizontal and the other is vertical.

“把横竖过来后...11...不对...2！”希斯莱最后在羊皮纸上写到112/2=56。

"Professor Dachikos! You are fifty-six years old, right?" Sisley raised his hand and said.

Professor Dachikos applauded in surprise after hearing Sisley's answer.

"That's right, I just celebrated my 56th birthday some time ago. Tell me, Mr. Thorne, how did you calculate it using a lonely number 7!" Professor Dachikos said and pulled Sisley away excitedly. Got on the podium.

"Count it?" Sisley asked, noticing Professor Dachikos' wording.

"That's right, for mathematical divination, it's more accurate than divination. Don't be so coy and tell me how you figured it out." Dachikos said.

"The process is a bit outrageous." Sisley said a little embarrassed.

"That's right, number divination is like this. As long as your logic and association skills are sufficient, no matter how outrageous the numbers are, you will find the correct answer. Now let's talk about your calculation process." Professor Dachikos said.

"Okay, let me tell you directly, the number seven, and Professor Dachikos's buttons, are also seven, but only three are buttoned, so I subtracted the three buttons from the seven buttons in total, leaving four. button."

"Then multiplying the number seven by four equals twenty-eight. Then I noticed the blackboard with the number seven written on it, and thought of the four corners of the blackboard, which is twenty-eight times four, which is one hundred and twenty-two."

"But one hundred and twenty-two is a bit too old for you. I felt something was wrong, so I looked at the number 7 on the blackboard. After taking it apart from the turning point, there were a vertical 1 and The horizontal 1 adds up to two, and one hundred and twenty-two divided by two equals 2. This is my process, it’s a bit too outrageous..." Sisley was already a little embarrassed at the end.

"A perfect mathematical divination, you added ten points to your college, and ten points to Gryffindor!" Professor Dachikos said excitedly.

[I admit, digital divination seems a bit ridiculous, but I did have this experience when I was a child. When I was testing words, I just made two random strokes, and he muttered a lot, but some of them were correct, and it was so scary]
