"Vicott, come first." Jack smiled and looked at the shy demon candidate.

Vicott nodded slightly, but his voice was not very confident, and he replied hesitantly: "With this type of engine, the heat resistance of the energy return wheel supercharger is not high, and if the spacecraft jumps more than ten times in a row faster than the speed of light, it may cause this kind of failure in the model." ”

"Well, that's right." Jack nodded with satisfaction: "Your foundation is still okay, but show some confidence when you speak." ”

"Yes!" Vicott bowed respectfully.

"Is there anyone else to answer?" Jack smiled and looked at the other four candidates.

Three of them continued to raise their hands, but Beichen remained motionless.

Jack's eyes glanced at Beichen, and then smiled: "Breno, you say!" ”

Brenor was the orc among the five candidates, and when he heard Jack call him, he quickly nodded and said, "Yes." Based on the data on the model and the location of the failure, I come up with the possibility that the engine was hit by a stream of strong magnetic particles at two quadrant angles of incidence, which caused such a failure. ”

"Correct." Jack praised: "This answer requires complex calculations, and it's rare that you can think of it in such a short time." ”

With that, he looked at the remaining three again: "Who's next?" ”

Sou! Kevins, and finally the demon, raised their hands almost at the same time.

And Beichen still didn't move......

……

"You see, the immortal still hasn't raised his hand."

"Looks like he's really stumped! After all, he is a cultivation maniac, and he can memorize the basic chapter in the first exam, I'm afraid it's just that someone taught him to memorize it before entering the school. But when it comes to practical problems, it's stumped. ”

"Sure enough, it didn't work, when I took the first test just now, I saw that he memorized so fluently, I thought this immortal was going to counterattack, alas, it's too disappointing......"

Many people sighed, when Beichen fluently recited the basic chapter just now, it was really eye-catching. However, looking at the situation at the moment, it is estimated that this is the end of it.

……

Of course, no one knew what Beichen was thinking, but at this time, Kenvins and the demon raised their hands, and Jack asked the demon to answer first.

"The reason I analyzed was that the part of the second stage propulsion unit on the side of the spacecraft was hit with an amplitude of 30.85, which caused this failure." The Majin's answer was succinct.

"Correct." Jack smiled lightly and nodded.

Kenwensi's heart suddenly tightened at this time, this question is indeed difficult, even if it is him, he only thinks of four possibilities, and now he can answer, there is only one possibility left, at this time, if Beichen raises his hand first, isn't he finished?

After thinking about it, he couldn't help but look at Beichen twice, thinking to himself, could it be that this immortal really wanted to make such a move?

At this time, he couldn't help but get nervous, staring at Jack intently, for fear of losing his last chance.

"So, ...... next"

Before Jack's words could be finished, Kenwenth hurriedly raised his hand.

"Oh?" Jack was stunned for a moment, only Kenvins raised his hand for the remaining two, but Beichen had no intention of scrambling.

At this time, Jack couldn't help but be interested, I don't know if this Beichen really doesn't understand, or what, he actually gave up four chances to answer in a row.

"Look! The immortal still didn't mean to raise his hand! Someone finally exclaimed.

"He really doesn't understand!"

"You say...... Could he have already come up with a fifth answer? Someone wondered.

Immediately someone retorted: "Impossible! All of us in the room, has anyone come up with a fifth? I thought I was close to graduating, but I still couldn't figure it out. Not to mention a freshman! ”

"Yes! The fifth answer should be extremely difficult. The purpose of this question is not to really let you think of all the possibilities, but to test your reflexes and calculation speed. Fight for the top four answers. I think that with the level of our students, it is impossible to come up with the fifth type, and the existence of the fifth type is just to make the competition of the first four more intense. ”

"Well, you have a point. Looking at this round, Kenwens raised his hand in such a hurry, which means that even he can't think of a fifth answer. ”

……

The people in the audience said one by one, and sure enough, no one could come up with the fifth answer. Everyone has already decided that if Kenwens answers correctly in this round, Beichen will lose.

Jack's eyes flashed, but he was not in a hurry to ask Kenvins to answer, but looked at Beichen for a long time.

He didn't quite believe that since Beichen could memorize the basics, he couldn't solve this problem. Could it be that Beichen is really just rote memorization and has never studied it seriously?

In fact, the students' guesses are good, this question is a test of students' reaction and calculation skills, the fifth answer, not from the book to look at the theory can be understood, this is the need to have many years of experience in repairing spaceships, to come up with the answer, he also doesn't believe that Beichen can come up with it.

"Looks like you're done here!" Jack sighed secretly.

"Well, then, Kenvins will answer!" He quickly returned to a smile and looked at Kenwenth.

Kenwensi nodded lightly, glanced at Beichen next to him, and smiled coldly. Soon, he replied: "My answer is that the power of the energy processor in the core of the spacecraft is too large, which causes the more fragile crystal conductors in the R and C regions to have abnormal pulses, and after the following chain reaction, it eventually causes such a failure. ”

After that, he enlarged the calculation formula in the light brain and played it back using a holographic projection.

Jack glanced at Kenvins' calculation formula, nodded with satisfaction, and said, "Yes, you answered the second difficult answer. You're even better than your father! ”

Hearing Jace's praise, even if he was as proud as Kenwens, he couldn't help but smile. But he still made a very modest expression and saluted Jack.

……

At this time, the audience also exclaimed.

"I really didn't expect Kenwens to be able to answer the fourth answer in such a short period of time! And with such a beautiful formula, you know, he's a freshman! And I've been studying for two years, but I can't imagine this! Alas, will I be able to graduate or not! ”

"I didn't expect that! Is this the fourth answer? ”

"I've come up with the answer. It's the fifth answer, and I'm incomprehensible! ”

"Immortal, what should you do now? Hehe, are you finally going to be eliminated? ”

"You deserve it! Let you practice in the study! Ha ha! ”

……

Jack heard the scene getting noisier and louder, and although the examinees couldn't hear the audience, Jack coughed lightly twice and suppressed some of the restlessness.

"Although this is a public assessment, it is still an assessment after all, so don't make a noise." Jack waved his hand.

Subsequently, Jack finally set his sights on Beichen.

"So, are you going to give up?" Although he spoke in a smiling tone, there was an inexplicable sense of seriousness in people's ears at this time.

Who knows, Beichen suddenly heard Jack say this, and was stunned for a moment. He smiled bitterly and said, "Your Excellency, how can anyone persuade the candidates to give up?" ”

"Don't give up? Do you still have to answer? Jack was even more surprised.

"What? Won't he give up on that immortal? The audience was also stunned, and the entire auditorium fell silent for a moment.

Kenvinth was also taken aback, he frowned tightly, and looked intently at Beichen, who was still calm. Does this guy want to come up with a fifth answer? Impossible!

At this time, in the audience, the lonely orc sitting in the corner, the face that had been gloomy because Beichen did not raise his hand, suddenly regained its brilliance, he was different from others, and at this moment he was looking at Beichen with anticipation, as if he believed that Beichen could answer.

Of course, only Beichen himself knows what it is.

I saw that Jack quickly regained his usual demeanor, and said with a slight smile: "Of course, the opportunities are fair, since you are sure, then please stand up and explain the fifth answer to everyone in person." ”

After he finished speaking, he immediately shut up, just looked at Beichen quietly with a pair of smiling eyes.

"Can he really surprise me?" This was what Jack was thinking at this time.

Beichen heard Jack call him out, and he was not nervous, got up and left his seat, walked to the rostrum, and stood next to the holographic projection model.

"As you can see, this engine is the No. 2 engine on the flank of the Blue Star-type short-haul spacecraft. This engine was first produced by Blue Star Aerospace in the Milky Way and has a history of 100,000 cosmic years, which is equivalent to more than 2 million Yasuo years! Beichen pointed to the holographic projection model and said lightly.

As soon as he said this, the scene suddenly became noisy again.

No one expected that Beichen would start with the engine production company. At the moment he is like a professional, not a student. That natural gesture, pointing to the holographic projection and talking eloquently, didn't even look like he was taking an exam, but like he was teaching.

Jack's eyes lit up at this time, and he hurriedly raised his hand to signal Beichen to continue.

"You can find that the fault is in red. This thing, I believe many predecessors know what it is, that's right, it's the three-body deflector! ”

The title said that there was a strong irregular vibration in the three-body deflector, and there were actually many reasons for this vibration. However, judging from this model, the vibration of the three-body deflector did not affect the other parts of the engine. In other words, the strong irregular vibrations mentioned in the title should be the frequency, not the amplitude. Because if the amplitude is strong, there is more than a small part of the fault. ”

"So the question is, what is the reason for the vibration that is so small in amplitude but so strong in frequency? After my analysis, the most likely cause is the softening of the energy colloid in the three-body deflector. ”

"In the basic chapter, I believe many people are familiar with the history of Bluestar Aerospace. Although Bluestar Aerospace has been building spaceships for many years, there are still many technical difficulties that cannot be completely overcome. One of them is the softening of the energy colloid. ”

"For every 100,000 energy gelatins produced by Bluestar Aerospace, one will have a softening problem soon after use, causing the three-body deflector to lose stability and the engine to fail sharply. This situation has remained unresolved for many years. So, in the end, I came to the conclusion that the engine in the holographic projection model failed because of its own material problems. Unfortunately, the energy colloidal used in its three-body deflector is exactly one of 100,000, which is an unqualified material in itself! ”

When Beichen said this, he smiled faintly: "Congenital defects, there is a problem of softening of energy gelatin. That's my answer. ”
