"Dismantling the above equation, we can get four sets of numbers, each of which represents an energetic point of the hedron. That's right, it's a low-capacity hedron with only four points of energy activity. After finding all the energy active points, you need to use your magic power to go deep into the crystal, take the energy active points as the center, and compress the crystal energy inward, and then you can cut it. As for the hedron synthesis that will be talked about in the future, it is also necessary to perform magical operations on the energy active points. Therefore, the dismantling calculation of the equation is the basis of spar processing, which is very, very important, and every calculation step must be cautious and cautious, and no mistakes are allowed. Remember, it is not only about your achievements, but also about whether you succeed or go bankrupt in the actual cut, and whether you make a fortune or get blown up in the actual synthesis. Your own property, your own security, is to be careful to decide for yelves. ”

"Let's assign practical homework, and each person will go to the experimental teacher to get a microsized spar of fifty terrs and cut it back, and give it to me in the last class the day after tomorrow. I don't ask for shape, I don't ask for position, I just need to see that there is at least one cut on it. ”

"Now class is over. ”

After Vivien finished the lesson, she sat down at the lectern again, her arms resting on the lectern, her chin propped on her hands, staring at the sky outside the window, and then falling into deep thought, letting the students pass by her without any reaction. After a few minutes, when the students were gone, Catherine, who had been sitting in the back row of the classroom, stood up and walked to Vivien's side, tilted her head and stared at Vivien for a while, and seeing that she still did not respond, she skillfully took out a rope sleeve from her pocket and put it on Vivian's neck.

"Hey, big sister, what are you doing?" Vivien was startled, dodged the rope noose, and protested dissatisfiedly, "Why do you want to use the rope to lass me." ”

"Hey, you're still awake, and you're not in a state of distraction. That's not right, I've never seen you stay awake after class. Catherine stroked her hair awkwardly and smiled as she put away the noose.

That is to say. Vivien lowered her head slightly, rolled her eyelids and glared at Catherine, gritting her teeth and saying, "Did you drag me out with a rope every time before?"

"Hey, hey, it's a nice day. Catherine twisted her face to the side, her eyes wandering.

"Hmph. Vivien snorted heavily, turned away from Catherine, and looked back at the sky outside the window.

Catherine smiled a little disappointedly, stepped forward and took Vivian in her arms, rubbing Vivien's hair: "Let's go, don't think about it, let's not think about Lina's stupid fool, let's play by ourselves in the city and have a harvest festival by ourselves." ”

"Shall we play by ourselves?" Vivien asked, looking back at Catherine, "Where are you going?"

"Of course I won't go back, today is a harvest festival. Catherine said in an exaggerated tone: "You only have one time a year, how can you spend it at home." I've already planned that we'll go straight to the Violet Restaurant in the business district for lunch, and then go to the Knowledge Theater in the North City District to listen to a concert, and there has been a tour of the Elf Orchestra just going on in the last two days. After the concert, eat your favorite seafood at the Severn Hotel for dinner, drink and dance at Adventurers' Land, and play until the night before going back to bed. ”

"Wow, eldest sister, are you crazy?" Vivien said in surprise, "This trip will cost at least three hundred gold coins for two people, right? ”

"Of course I'm not crazy, I'm very generous. Catherine tilted her head and said proudly, "Have you forgotten that two years ago we had a carnival in the Adventurer's Paradise because of the promotion of the adventure party to the Silver Rank? and a year ago, in order to celebrate that you received an invitation from the Tower of Stars to become one of the thirteen exclusive laboratory masters, we invited all our friends to have a barbecue party in the courtyard. So, I'm not too stingy, and I'm extravagant once in a while. ”

"And then hide in the house and secretly wail and regret it?" Vivien said with a snicker, covering her mouth, "and then gnawing dry bread for a month?"

"Hey. Catherine glared and puffed out, "I've said I'll stop talking about dry bread." ”

"Hee-hee. Vivien suddenly put her arms around Catherine's neck, kissed Catherine heavily on the face, and said with a smile: "It's better to be the eldest sister, and she will try her best to make me happy." ”

Catherine slapped Vivien's ass on the buttocks, waved her hand and said, "Don't be numb, let's go, let's go and eat." ”

"Alright, let's go. Vivien was also interested, jumping down from the stool and holding Catherine's arm: "Go to dinner, envy the stupid girl Lina." ”

The two girls held hands, snuggled up to each other, walked out of the classroom, out of the school building, and out of the school gate. As soon as he walked out of the door, he heard a buzzing roar of machinery behind him, and in the roar, a person shouted behind him: "Yo, two beautiful young ladies, please wait." ”

Catherine and Vivien turned their heads at the same time, squinting at the midday sun. Under the harsh sunlight, a golden magic car stopped on the side of the road, with a streamlined body, a wide body, a windshield made of transparent crystals, and even a large portrait of a girl pasted on the bottom corner of the windshield, everything was so familiar.

A man sat straddling the magic car, his hands pressed the control rudder and magic input on both sides of the front of the car, wearing a black trench coat, wearing a black wind goggles on his face, and said in an exaggerated aria: "Girls, you see, today's weather is so beautiful, the sun is so bright, the autumn wind is so warm, it is a good time for an outing date, I wonder if I have the honor to invite two beautiful young ladies to spend this wonderful day together?"

"Haha, it's Pannis, why are you so weird. Vivien smiled in surprise, her eyes suddenly lit up, and she said loudly, "Ah, can you ride this kind of magic car, can you drive for a long time?"

"Of course. Pannis rode on the magic car, gave a thumbs up, and showed a big smile, his white teeth shining in the sun: "Pannis Tour, Angus Village Day Tour, departure at noon, return in the early morning, tube delivery, safe and cheap, your best choice for travel." Two beautiful girls, there are just two places left, do you want to sign up?"

Vivien and Catherine glanced at each other, with a look of surprise in their eyes, nodded to each other, and said with a smile, "We're going to sign up." ”

"Then get in the car. Pannis patted the front and back seats of the motorcycle, took out two windbreakers and handed them to the two girls: "Sit down and get ready to go." ”

Vivien sat on the front seat of the locomotive, her hands on the armrest fixed at the front of the locomotive, and Catherine straddled the back seat of the locomotive, wrapping her arms around Pannis's waist. Pannis's hands injected magic into the rudder at the same time, and the roar of the locomotive gradually increased.

"Goal, Angus Village, time, three hours, departure. With Pannis's shout, the roar of the locomotive suddenly decreased, and the locomotive, which had been stationary, began to move forward slowly, slowly accelerating, and headed for the city gate.

"Pannis. Catherine, who was sitting in the back seat, shouted aloud to the roar of machinery, "Where's Lina?"

"I should still be sleeping in Angus Village. Pannis, facing the wind, replied hoarsely at the highest volume: "I lied to her in the morning that I had some personal matters to deal with, and I didn't tell her what I was going to do, and I surprised her." ”

"yes, scare that idiot, who told her not to play with me, cough cough cough. Vivien danced loudly in agreement, but got carried away, choking on the wind brought by the speed, and coughing repeatedly.

"You're still in Angus in the morning?" cried Catherine, "this car is at home, and you didn't ride it, how did you get back from there in two or three hours?" ”

"I have dedicated transport. Pannis's mouth smirked: "An animal called a vehicle." ”

"It's nonsense again, how can there be that kind of animal. Catherine shouted angrily, "And I haven't asked you yet, you can actually drive a magic car, which means that you can also do magic? Is there anything you wouldn't have?"

"Haha, haha. Pannisa laughed twice and shouted, "What are you talking about, the wind is too strong for me to hear." ”

"Bastard Pannis. Catherine punched Pennis twice in the back, and couldn't help but shout, "You just said that Lina is still sleeping?"

"That's right. Pannis shouted: "I didn't sleep last night, I guess she didn't sleep much the day before yesterday, she must make up for sleep today, otherwise she won't be able to support the night festival." ”

"Did something happen?" Catherine asked, worriedly, "why did she stay all night?"

"There was an evil incident in the village of Angus. "We had a small adventure. Although there were some problems in the process, fortunately, everything was solved in the end. ”

"What are some questions?" Catherine frowned and said uneasily, "in danger?"

"There must have been some danger, but you see, I'm fine, and there is no problem with Lina. Pannis replied nonchalantly: "After all, it is normal for adventurers to encounter some dangers. ”

"Okay, it's fine. Catherine was still not reassured, but as Pannis said, both of them were safe in the end, and that was enough: "I'm curious what happened to you." ”

"Haha, that's a very wonderful story, I'll let her tell it to you when I meet Lina. Pannis saw that he had left the gate of the western city to the outside world, and the pedestrian carriages on the road were becoming scarce, so he pushed the joystick next to the control rudder with his thumb, and at the same time increased the magic output, so that the speed of the magic car increased again: "Everyone be careful, I want to speed up." ”

The roar suddenly increased, and the demon cart whistled along the main road between the city with a strong wind, raising a cloud of dust.
