Star Trail went straight to the podium and handed the disc to the man.

"What are you doing?" the man took the disc in one hand, his tone dissatisfied.

"There is no rule in the examination room that you must hand in the papers after you finish it, right?" the corners of Xing Rail's lips raised slightly, "Are you afraid that it will be difficult for a leader to check it?"

The man's eyes widened, and he said in a deep voice: "You can eat things indiscriminately, don't talk nonsense!"

As he spoke, he connected the recording disc to the magic source and detector, and snorted coldly: "Let me tell you first, if you fail to pass the rating, you will have to conduct a rating test every week, and if you fail three times, you will be directly dismissed." ”

"Thanks for the reminder. Star Track's tone was flat, barely rippling.

"Hmph!" The man saw that he was so calm, but his heart was uncomfortable, and he always felt strange and inexplicable.

At this time, the crystal of the detector floated, and a string of numbers appeared on the light curtain.

The man's eyes were one, as if he had seen a ghost, "43%?!impossible!"

He knew that it was impossible to achieve this energy efficiency with that kind of recycled low-quality silver, but the numbers in front of him would not lie.

The man looked at the star track, "Did you secretly change the material?"

"You mean, did you really give me inferior materials?" Star Rail laughed.

The man found that he had said that he had leaked his mouth, his eyes sank, and he re-tested it, but the value was not deviated.

He couldn't understand that although the three-star third-order circuit was not a difficult thing, it was a recycling of inferior silver after all, and there was no reason to achieve such a high energy efficiency.

Unless it's a master who makes up for the lack of material with an extremely detailed circuit, but it can't be used in just four hours!

The man wanted to test it again, but Star Rail said, "That's enough, right? ”

The man was stunned for a moment, and his face was a little ugly when he saw a few remaining people standing behind the star track.

"Do you want to make me crazy?" Star Rail bowed his head and said, "You're just an aspiring errand, don't you have to work so hard, right?"

The corners of the man's eyes twitched, and he gritted his teeth and said, "Pay attention to your words and deeds, I am your teacher!"

"Don't defile those two sacred words. Star Rail's eyes froze, staring straight at the man, flashing sharply, "You don't deserve it." ”

The man's heart jumped suddenly because of the star's gaze, and he felt frightened, and his figure involuntarily stepped back.

Star Rail stood up straight, and said with a smile: "You can set the results, right?"

The man gritted his teeth and gave Star Track a C- on the record crystal.

Seeing this, Star Rail nodded and strode away.

As soon as he came out of the lobby, he saw Kang Wu and a few students discussing something, and Kang Wu seemed to have been paying attention to the movement here, and saw him at a glance.

"Is it finally done?" Kang Wu smiled at him, without kindness or malice, "You can probably stay here for two weeks, take this opportunity to experience campus life, although it may not be as good as you think." ”

"Is the Wang Family Academy so strict?" Star Rail smiled: "Take a C-you won't be expelled, right?"

Kang Wu's expression froze, and his smile froze on his face.

"You should thank me for giving you more time to trouble me. Star Orbit: "But you have to be careful of capsizing in the gutter, after all, the Wang Family Academy is not the only one of the Witt family. ”

Kang Wu's eyes narrowed, and he heard the meaning of the star track.

"Do you think the Green family needs a nobody like you?" Kang Wu raised the corners of his mouth, and his smile was full of disdain, "You can't help but think too highly of yourself." ”

"Maybe not in the past, but now, who's going to know. Star Rail smiled meaningfully, said no more, and strode away.

Kang Wu frowned, although he didn't want to admit it, what Star Rail said was indeed reasonable.

In today's situation, every student may be the target of the two families, because there will be a crucial election next.

Student Council President!

That would be the key to upset the balance.

Being overwhelmed by the star track, Kang Wu only felt a little depressed in his heart, strode to the classroom, and came to the slightly chubby man.

At this time, the man was also figuring out the recording disk, and Kang Wu said in a deep voice: "What's going on? That kid got a C- rating?"

The man shook his head and said, "I don't know what the situation is, I'm trying to disassemble the circuit to find out." ”

"Then dismantle it for me immediately!" Kang Wu snorted: "I want to know, whether it's your problem or his!"

When everyone heard this, they were all worried.

The man straightened the recording disc and was about to start the reverse circuit, but the recording disc suddenly flashed with a burst of thunder and crackled.

Everyone was shocked and retreated sharply.

But the thunder was not strong, it only flickered a few times on the burning disk, and then disappeared, and then there was a puff of black smoke, which smelled bad.

"What's the matter?" Kang Wu said angrily, "Didn't you take the mana source?"

"Take it......" The man hurriedly said, "I took it a long time ago!"

As he spoke, he cautiously picked up the recording disc and examined it carefully, his eyes wide open, "This is the ...... Energy storage circuit?"

"What?" Kang Wu said, "Energy storage?"

"Right...... He secretly carved an energy storage circuit to preserve the magic power that had just flowed...... "The man was surprised: "Using this magic power to destroy the circuit in this burning disk, it has been ...... Can't check it......"

The more Kang Wu listened, the more his face sank, in the end, they were all tricked by the star track, the key is that they don't know what that circuit is all about.

Since the star track chooses to destroy, there must be a cat in it, but there is no proof of death at this time, so it can only be stopped.

On the other side, Xing Rail calmly walked out of the teaching building, and couldn't help but smile when he saw a flash of thunder in the classroom.

This time, he actually took a trick.

With that kind of inferior silver, it is impossible to form a stable and efficient circuit, so he simply gave up stability and made a circuit with an extremely limited number of uses to maximize the utility of that inferior silver.

This kind of circuit can achieve a certain amount of energy efficiency, but after two or three magic cycles, it will be completely scrapped.

This is also the reason why Star Rail deliberately prevented the man from continuing the experiment.

And the reason why he chose to be so late and not the last to come out was naturally so that someone could play this cover, and also to let the energy storage circuit be activated at a reasonable time.

After resolving this disaster, Star Track was in a good mood, he returned to the square, waiting for the next step to go to the student dormitory, but saw a huge light curtain floating on the artificial lake at this time, with four lists on it, which actually corresponded to the student rating status of the four basic courses.

At this point, the ratings are nearing the end, and the top 10 students, their names and profile pictures are beginning to appear on that list.

The first column, which was the Demon Warrior Column, had already appeared to three or four at this time.

"Kyle, that guy should be able to stay in the first place, right?" Star Rail thought to himself, after all, he was a top student at Garand Academy, and that surname was definitely not simple.

But to his surprise, it wasn't long before the name 'Kyle Rog' appeared on the second line.

The name of the first row is, Kidd Fran.

When Star Rail saw that name, his pupils shrank suddenly, and his heart jumped suddenly.

"Impossible......" His heart fluttered as he remembered the words of his teacher who had called the black dragon in the ruins of the gods.

'Dragon of the End' Afrankid?!

The second more.
