Early in the morning of May 6.

The people who had already registered yesterday came to the testing hall on time, and the crowd was daunting.

"It's better not to tell me, so many people are going to take the test......" Nian Yubai straightened his robe with a bitter face, he had just been pushed around and stepped on, and someone's good mood had been swept away.

"Well, then you can't stop others from watching the excitement, today according to the snow calendar, it happens to be the first day of January, the first day of the new year, according to the customs of our Liyan clan, everyone will not stay in the house, they will bring their relatives and friends out to hang out, and the technical test and theoretical test once every ten years are also selected on this important day, they come to see what's strange?"

"What? Don't you treat the family reunion in the house for the first day of the new year, but you still do the opposite and run out of the house? I don't understand, and don't you think it's really sad to take the exam on the first day of the new year?"

If you do well in the exam, you will be very happy in the year, and if you don't do well in the exam, then you should urge yourself to study and study hard in the new year. ”

"I don't know what you think...... Nian Yubai raised his forehead speechlessly.

Tando shook his head as well, "I don't quite understand what you're thinking. ”

Alas, the generation gap between the clans.

"Come on for the exam, we support you spiritually!" Yan Xiaoyue patted Nian Yubai's shoulder, full of schadenfreude.

Nian Yubai glanced at him and said, "Xiao Yanzi, I see that you have a lot of experience in technical testing, why don't you help me take the test on my behalf?"

"Then how can you do it, the main thing to develop walkie-talkies is a few of you, a righteous and awe-inspiring young man like me would not dare to take the credit of others for himself!"

Bai Muhan wanted to speak and stopped, and finally opened his mouth to comfort: "It's okay Yubai, although you are in a bit of a hurry to review, you have to try, what if you bump into a passing grade?"

Nian Yubai was suddenly hit hard: "That's enough! For the first time, I found that serious people hurt people and the lethality is even greater!"

Yuling said calmly: "It's okay, the multiple-choice questions rely on Meng, the fill-in-the-blank questions rely on guessing, and the essay questions are broken blindly, sixty points is still hopeful." ”

"Ah Ling, why do you look so experienced......

"I can't remember the experience of many years ago, if something goes wrong, don't look for me. ”

Originally, Nian Yubai was reluctant to take the exam, and watching others rack their brains and work hard is the joy of life, but as one of the main forces in the study of walkie-talkies, if one of the two types of first-level tests can't pass, then his words will be too uncredible, and when the time comes to introduce the operating principle of the internal formation of the walkie-talkie, he will definitely be questioned by all kinds of questions.

So in the end, it goes without saying that Tando and Saiba, Yuling and Nian Yubai also have to go through the motions, during this time, the two of them are tossing the walkie-talkie, and they are also memorizing various theoretical knowledge by rote, and they also have to learn the Liyan language, fortunately, the soul master is definitely a hundred streets out of ordinary Liyan people in terms of memory.

Originally, Tando brought a bunch of books, and he was worried that Yuling and the two would not have time to finish them, but when he found out that these two guys were scanning at the speed of light, and he finished a book and remembered it very firmly, Tando's worldview collapsed.

Of course, it's one thing to write it down, and it's another thing to understand it, so Nian Xiaobai is very melancholy.

After the four of them squeezed through the crowd and entered the formal test room, the surroundings were suddenly quiet and empty, and it happened that the weather was good today, and the sun swayed in through the window, reflecting a golden light and shadow, warm and quiet.

However, the testing system of the Li Yan tribe is not as strict as on the earth, the seats are all casually sitting, and there is an opaque barrier between each two seats, which is actually quite similar to the ancient imperial examination.

Yu Ling casually picked a position by the window and sat down, the stone table in front of him was actually very rough, only the top was polished, as smooth as a mirror.

Think about how many years I haven't taken the exam, although it was not a good memory back then, but now I have an inexplicable nostalgia and emotion.

Sometimes I have to say that the Li Yan clan is really a special race, some aspects seem primitive and backward, but some aspects are very modern, especially the flying machine is definitely an amazing invention, throwing the Terran cultivators of the Seventeen Domains out of a chasm.

It didn't take long for a woman from the Liyan clan dressed in black to appear at the table, put a stack of animal skin paper and a dark ink pen in front of Yu Ling, and looked at him curiously.

Because of the Zheng'er Eight Classics exam, so Ji Gu was put outside, and Yu Ling finally remembered that Gu Hydra gave them a few red chains like headdresses at that time, which could play a role in communication, so he hurriedly put them on and said thank you.

The woman of the Li Yan clan smiled kindly and said, "It's the first time I've seen a foreigner come to take the test, good luck." ”

After she left, Yu Ling picked up the stack of animal skin paper and counted it, she couldn't help but feel a little dizzy, isn't the Li Yan clan really joking, just such a morning effort, let them solve so many questions, no wonder the first-level test alone can brush off ninety percent of the people.

But......

It's still the original recipe, and it's still a familiar taste.

Although there is no ABCD option, is there a difference between one, two, three, four, five, six, seven?

However, the multiple choice questions of the Li Yan clan are really not easy to obscure, seven options are placed in front of you, how good luck can you be right?

Yu Ling was suddenly a little worried about Nian Yubai.

Although the Liyan script that I learned in a hurry for a month is not 100% perfect, these questions are not picked, so as long as you understand the general idea, you can almost start writing by hand.

By the time Yu Ling quickly filled in a dozen pieces of parchment with only the last page left, most of the morning had passed, and just when he felt that time was not enough, he suddenly found that there was actually a question on the last piece of paper.

Please introduce the most commonly used energy converters at this stage, and explain their internal structure and working principle.

Note: If relevant improvement suggestions are made, additional points can be given as appropriate.

In fact, Yuling wants to make some suggestions on the design of this set of test papers, as an exam question, how can there be no question number and score, and there is not even a clock, which is too inhumane, so how can candidates grasp the time?

This is all obsessive-compulsive disorder forced out by countless exams when I was a child, and it seems that there is no cure.

Yuling immediately began to write "compositions" in a free manner, fishing out the five common energy converters one by one and explaining them one by one, not only explaining the structure and working principles, but also writing down the advantages and disadvantages together.

“...... To sum up, the above five energy converters have their own advantages and disadvantages, among which the 'Flame Nine' energy converter designed by Komogarda has the most improvement value, if you want to overcome the problems of complex pipeline design and slow start-up operation, you can consider improving the operation efficiency of the pipeline, here you can make two attempts, one is to reduce the number of pipelines, and the other is to design the pipeline parallel structure ......"

"Vallegada's 'Tempest' energy converter also has some room for improvement, its energy consumption is too large, on the one hand, we can find energy-saving energy and improve the energy conversion rate, on the other hand, we can start from the optimization of the internal structure, we can appropriately extend the length of the pipeline, and make the diameter smaller......"

When Yu Ling put down the thin pen made of dark ink stone, the woman from the Li Yan clan also came over and reminded: "The time is coming, if you haven't finished writing yet, hurry up." ”
