Chapter 9: The Truth

"Third brother, if you don't wake up yet, you'll be in trouble at night."

"Mingtou, you look at her appearance, she is still a high school student, in fact, she should be what she will look like ten years later, that is, she will have to be 30 years old."

"Third brother, you're right, why didn't I find out."

"It's a special kind of sealing, and that's why she hasn't been discovered for so many years."

"Bring the pen"

There are even seals and odd seals, each with its own effect. Sealing is a spell full of mysteries.

This may be self-sealing, that is to say, without the help of outsiders, she will not be able to escape, she should be afraid of death, so she sealed herself, but she never expected to come out. That's 10 years.

The third brother began to draw some spells, and I, but I couldn't help anything, I didn't expect the third brother to be so powerful, this senior sister is also awesome, just when I was curious about why I was surrounded by people who knew how to spell, the senior sister actually woke me up.

Hello senior sister, my name is .....

Before I could speak, she said first: "You are picking up the light, I didn't expect to see you here." ”

Miscellaneous....... What, you know me? Have you seen me anywhere?

Yes, his name is Shiguang, my name is Wang San, and you can call me the third brother.

I pinched the third brother to hint at what he was talking about.

"Don't reveal your identity like this, we still have to set her words, you fool."

"Yes, yes, yes, it's still the third brother who you think about thoughtfully."

Hello, my name is Meng Yao, and you don't have to call me Senior Sister.

Yes yes...... What the senior sister said was, phew, what the classmate said.

"Can you tell us what happened ten years ago?"

"Ten years ago, we found out about the teacher's ugly behavior, and wanted to help the classmates expose it, but the head teacher refused, it seems that our head teacher has something in the hands of the head teacher, just like that, he chose to be silent, unexpectedly, before school the day before the college entrance examination, the head teacher of a class rushed in directly, and hacked our head teacher to death, followed by us, we tried to run out, but were sucked back by a strong force, so none of us were spared, finally, Even the first class did not escape the fate of this death. ”

"Third brother, what the hell is this powerful power, and why does she know how to seal, and ............"

"Classmate, do you know how to escape?"

Know, as long as you complete the test questions of the Five Spirits Array, you can go out. Meng Yao scratched her head.

"Shiguang, aren't you a science student, this is a physics problem, but for us liberal arts students, it's like a computer garbled code, why don't you try it."

"Quick, what's the topic."

With that, Meng Yao moved the chalk box on the podium around, and a question slowly emerged on the blackboard.

The powerful five-spirit magic circle at the top of the Lock Demon Tower is actually a horizontal section of an invisible five-spirit conductor ball (originally uncharged) that has passed through the center of the ball. The circle of the five spirits of water, fire, thunder, and terroir on the circle is also the cross-section of the center of the five small balls. These five small balls are the five cavities in the big ball, and the middle is filled with the spiritual power of the corresponding attribute. It is known that the radius of the big sphere is R, the radius of the small sphere is r, and the center of the five spirit circles is R/2 away from the center of the circle, and there is a fixed charge at the distance from the center of the small circle to the center of the big circle r/2 on the line from the center of the small circle to the center of the big circle, and the conductors with a small linearity (which can be regarded as point charges) are q, water, fire, thunder, wind, and earth, respectively, and all the spiritual power is concentrated on these charges. The spiritual power of the magic circle in the Wuji Pavilion of Shushan is equivalent to the point charge of Q, and it is believed that it is coplanar with the five spirit arrays at the top of the tower, and the distance from the center of the ball is 4R, and the potential energy they have together maintains the stability and life of Shushan. Now the fire vein has been opened by the burning sun, and the Q fire has reached the center of the fire spirit circle. Nangong Huang and his party had to artificially open up the remaining leylines. After they open the leylines, the charge of this property is released. When all the charges are released, they can be reset (the so-called Nopole).

(1) When the fire vein is just opened, the spiritual power value (electric potential energy) of the q fire

(2) What are the changes in the spiritual power (charge distribution) on each surface until the leylines are all opened up until they are reset? What is the spiritual power (electric potential energy) of Q fire at this time?

"Rookie topic, this question is very simple." The third brother said confidently.

"This is the formation of the game Fairy Sword 3, I don't know why this topic came out ten years ago, because the game didn't come out at that time. Also, I can't figure out what the identity of the class teacher is. The third brother said puzzled.

"Get me some colored chalk"

"It's also colored chalk, it's good to have an oily pen, you can make do with it." I sat down on the floor.

"Why don't you stupidly kill you, that chalk box was eaten by you?"

The Five Spirits Array is a classic formation in the Legend of Sword and Fairy series of games. In the Legend of Sword and Fairy 3, the five characters began to have their own attributes of immortal arts: Sedum (wind) Xuejian (earth) Nightshade (thunder) Zixuan (water) Changqing (fire), what attributes they are, it is best to stand on what position, there are words written on the position, you can still recognize it if you look carefully, and you can see it according to the color: blue water, red fire, loess, green wind, purple thunder.

Meng Yao poured out a box of chalk. I have so many colors every day, third brother, can you tell the difference, I asked with conviction.

The third brother said confidently, I still played for a month, but then let Lao Tzu kryptonite, I gave up.

"Stop the ink, hurry up and calculate the topic, I'll help you."

Meng Yao's expectant eyes on the side made me more confident in saving her out.

There is also the solution to this series of mysteries.
