Civilization and Harmony Hogwarts

Seven thirty in the evening.

According to the usual schedule, at this point in time, the little wizards should have finished their dinner long ago, either staying somewhere to finish their homework, or wandering around for "legal night excursions".

But today, because of the arrangement of the dinner, the time for the end of the dinner has been postponed.

In addition, Principal Dippet said that a new activity session would start at eight o'clock, so the little wizards chose to stay in the auditorium to recuperate in order to recharge their batteries once and for all.

The four colleges are in stalemate with each other, adhering to the policy that the enemy can't move and I can't move.

Even the little wizards who are usually lively and active are all ready to fight at this time.

……

When the hands of the clock point to [-]:[-], the candles above the auditorium emit a little bit of light.

At night in late autumn, even though the auditorium is brightly lit, the changes in light are still eye-catching.

The little wizards caught the change of light and shadow, so they all raised their heads and looked up into the sky.

Every tiny little light is actually not dazzling, but their number is really huge, scattered like stars in the night sky.

The little wizards subconsciously sighed in surprise, the voices were not loud, but they couldn't hold back the interweaving of many voices.

Then, the faint light floating in mid-air surged towards one direction as if attracted by something.

The position of each point of light is different, and the arc of the trajectory of each point of light is also different.

But they strangely merged into the same strands, flowing and converging in the same direction.

Like drops of water, rushing to one place along the terrain.

It is also like a series of charming and soft light belts, dancing and fluttering along the airflow.

Like fireflies in summer.

Like a bright galaxy.

The little wizards held their breath subconsciously, even though their mouths were opened wide in surprise at the sight, they still didn't make a sound.

Maybe it's because each of these tiny lights seems too small, and they are afraid that they will disturb them with any noise they make.

Finally, they slowly swam and gathered in one place, cleverly arranged and combined in mid-air to form a few lines of dazzling words——

The final Halloween event: The Ghosts Come Down.

Dear little wizards, as Hogwarts celebrates Halloween, your cheerful mood attracts monsters from the dark.

They hate joy the most and vow to tear apart all joy, bringing pain and wailing to the world.

At this point, they have come to Hogwarts.

Brave little wizards~

Grab your wands and let's defend Hogwarts and expel ghosts together!

……

These lines of text stayed in the air for about two or three minutes, and basically everyone in the auditorium read them clearly.

As a result, the shimmering light of the combination scattered in all directions, and after a while, a new text was formed.

The new text, which is in a smaller font than the previous one, contains some specific points about the final event, "Descent of Ghosts":

1. Little wizards should receive a special activity wand from the house elf at the entrance of the auditorium, and use it after entering the magic breath to activate it.

2. The active wand supports the use of all the spells taught in the Hogwarts School of Witchcraft and Wizardry curriculum. (Please pay attention to little wizards who have mastered private improvement spells and black magic, the active wand does not support the above spells)

3. The little wizard's score in the "ghosts come" part is calculated based on the strength of the magic spell released by the little wizard using the movable wand and whether the attack falls on the target ghost. (Spells cast other than active wands, whether or not they hit the target ghost, do not count towards the score, including but not limited to silent casting, wandless spells, and using your own wand...)

4. There are personal rankings and college rankings for the activity results, and the rankings change in real time.

5.个人排名前十名分别可以为自己的学院获得50-5分的学院分，奖励的学院分按照名次高低按5分递减。（即后一名总是比前一名要少5分的学院分奖励）

6.各个学院可以按照排名高低，分别获得100-25分的学院分，奖励的学院分按照名次高低按25分递减。（即后一名总是比前一名要少25分的学院分奖励）

7. The top ten individuals and the top-ranked colleges can get special rewards.

8. During the event, little wizards are forbidden to attack each other. Please keep in mind that this is a group event and requires everyone to work together! (Based on the particularity of the activity, the attacks between the little wizards holding the activity wands will be exempted by default, but hitting the companions will be deducted from the final score. The more times, the more deductions, each time The deducted points increase exponentially compared to the last time.)

……

"Wow! Cool!"

"What! Are there really ghosts?"

"But... what is that index?" There is always a little wizard whose thinking is different from others. Others pay attention to the content of the activity, and he is obsessed with the "index" mentioned in the main points.

It's a strange term I haven't heard before!

The little wizard frowned slightly, very puzzled.

"I told you to read more books, but you just didn't listen!"

"If you read two more math books, you won't ask such a question!"

A Muggle-born wizard with good grades who wanted to be admitted to the University of London in the future, but was cut off halfway by the Hogwarts admission letter sent by the owl, criticized those "illiterate" from families in the wizarding world "with heartache" "They.

But with these little idiots who have no mathematical foundation, they will not be able to explain it for a while, so he can only generalize and summarize: "For example, the first time you attack a classmate, you will deduct two points, the second time you will deduct four points, and the third time you will be deducted. Eight points for the first time, [-] points for the fourth time... more deductions each time."

The little wizards around heard:! ! !

Afu: Do you think you still dare to do something to your classmates? (smile crookedly)

Little Wizard: Don’t dare to move, dare not move... (Waves hands frantically and shakes head)

"This... is too scary, right?" A little wizard spoke tremblingly.

"Heh!" The little wizard who gave everyone the science index sneered and pushed his glasses, and said extremely cold words from his 37-degree mouth, "This is only the first time that two points are deducted. Three points are deducted for the first time, and 81 points are deducted for the fourth time, and if four points are deducted for the first time, 250 six points are deducted for the fourth time.”

"If you make too many 'mistakes', you probably won't get enough grades to deduct." He specially emphasized the pronunciation of the word "mistakes", and his probing eyes fell on a few students around him who looked a little embarrassed.

Everyone understands that this "mistake" does not necessarily refer to a real mistake, but just a long-planned excuse to make a mistake—using the excuse of "mistake" to trip up the enemy during the event or something.

Revenge for injustice and revenge for injustice!

"Hahaha... how come?"

Those little wizards with small calculations in their hearts were seen to be thinking carefully, and they were really afraid of the so-called exponential deduction model that had just been popularized by science, so they had to express their position regretfully, saying that their accuracy was good.

"My spells are very accurate, and such low-level 'mistakes' will never happen to me!"

"That's right! We didn't study for so many years in vain!"

"You'd better give me yes."

------

Let me review the exponential function for everyone: y=a^x (a is a constant and a>0, a≠1), the domain of definition of the function is R.

The function reads "y is equal to the constant a raised to the power x".

The three situations in this chapter are y=2^x, y=3^x, y=4^x.
