In less than half an hourglass, the rabbis were able to complete the arithmetic problems drawn up by the leaders of the watchmen.

"Don't you need to check again, kid?" His Royal Highness Luo Shan, as the chief examiner, kindly reminded the little green-skinned man in front of him.

Contrary to the scruffy goblins with their sloppy and smelly bodies, the rabbi and his brother wore elaborate white silk shirts, black bib pants, and shiny leather boots. The little bow tie around their necks made them look a little funny, and the eldest princess of the Whispering Forest felt that this outfit, which was said to have been specially designed by André Gosareth, looked a little ...... on the otherwise disgusting goblins Lovely!?

Yes, it's a word that doesn't quite match the goblins, cute. But the polite and neatly dressed in front of him, his eyes were a little nervous, and he couldn't help but glance around because of curiosity, which gave the noble and intelligent eldest princess a feeling like this.

"Thank you for the reminder, Your Highness Loxanne, but I've already checked it twice......"

I've checked it twice!?I've seen it twice and found that I don't know how much, right?

The elder beside the eldest princess, who was one of the questioners, felt that he was almost blinded by the "swish" writing speed of this goblin who spoke wildly just now! You must know that even he himself cannot guarantee that he can answer all the questions within half an hourglass, after all, he is only "one of the questions".

"Catrian, take a look first. Keenly aware of the ugly faces of the surrounding elders, His Royal Highness Luo Shan directly handed the "test paper" in his hand to the druid elders who held back his anger and did not attack.

"......" only glanced at it twice, and Catrion seemed completely stunned...... His strange expression attracted the attention of several other elders who were also the answerers, who were also very curious about what was written on the answer sheet.

It's just an arithmetic question, so what other shocking remarks can there be?

Then the four elders, who were staring intently at the answers, all fell silent, just like Katrion.

"How's it going?" the other elders couldn't help but ask because the atmosphere was a little delicate.

“...... Exactly. Catrion gave an irrefutable answer that he was not sure of, but which was in front of his eyes.

This answer made a few of the twelve elders who were not so good at arithmetic show a cautious and surprised expression, not to mention that they are now old and their thinking is far from what they used to be, and even when they were young, they could not correctly answer all the more than thirty questions in half an hourglass!

The last question in this exam paper is based on the days when the elves walked out of the Whispering Forest and fought the demon army at the foot of the limestone mountain, and asked to calculate the supply consumption of the elven troops in that three-month battle...... Although the data has been simplified to a certain extent, it is still necessary to calculate the huge consumption of 80,000 troops in detail every day! According to the actual situation at the time, there were several large reductions in the number of troops after several major battles, and different subdivisions were made for the rationing of front-line scouts, marksman brigades, druids, and sacrifices. Involved include food, water, arrows, bandages, ...... It seems that this is only the last question, but in fact, it can also be seen that there are several calculation questions about logistics supplies.

It took him less than half an hourglass to answer this kind of question that would make people dizzy!

――Is this little man's head full of numbers!?

"I'm done too!" said Gru, who felt the invisible pressure from his brother's submission of papers so long in advance, and wiped the fine beads of sweat from his forehead with relief.

An elder picked up his answer sheet and read it several times cautiously.

"The last question, regarding the consumption of bandages, seems to have missed a single digit, and the correct answer should be one thousand seven hundred and sixty volumes. He wrote one hundred and seventy-six volumes...... The other answers are exactly correct. ”

Because the last question is too computational, the answer actually only requires the result of the estimate, which has already been pointed out in the question. That is, the number 1,760 is actually correct as long as the answer is 1,700 or 1,0800, and if the estimate is within 15 to 2,000, it can actually be regarded as barely passing.

As a result, several elders picked up the two test papers and compared them - except for Gru's mistake, which seemed to be caused by negligence, all the answers in the two test papers were exactly the same!

If it weren't for the fact that the topics were all improvised by a few elders, they would have wondered if these two little men who were not amazing in appearance had used any special means beyond the rules!

"Dear Elders, have we passed this test?" Gru felt that the atmosphere in front of him was so oppressive that it felt strange, so he asked the result that he was most concerned about.

"Young man, your answer is almost perfect, why do you worry that you won't pass this test?" said Katrion, feeling a little strange.

"Isn't this particularly calculated exam paper based on completion time as the main criterion?" the simple goblin asked rhetorically, slightly innocently.

......

Maybe it's because of the outstanding performance in arithmetic, in other links. The elders all raised their expectations of the two goblins in other realms by at least a notch.

"Briefly describe all the elements you know, the magic, and their general properties. ”

"Light, darkness, fire, wind, water, ice, earth, lightning, life, and death...... Light travels in a straight line most of the time, but observable refraction occurs when there is a significant difference in temperature or when the propagation medium is changed. ”

"What is the state of switching mediums?" If it weren't for the previous arithmetic exam, the elders who were examiners would almost have thought that this guy was making things up with his imagination before.

Everyone understands reflection, but what kind of novelty is "refraction"?

"When light is shot into the water from the air, there is a certain degree of refraction, and when you put the chopsticks in the clear water, you can see that the chopsticks look bent on the surface of the water, which is a form of refraction. ”

This is a very common natural phenomenon, but is it related to the refraction of light? Bronze mirrors and reflections in water seem to have some similarities, if it is because of light...... This seems to be the most plausible explanation!?

The examiner himself was a little unsure, perhaps it was a little too reluctant to measure the smart little man in front of him with his own level.

"What happens when the temperature difference is obvious?" The elder's curiosity and curiosity had been successfully aroused by the goblin in front of him.

"Looking at a hot fire from a little farther away, looking through the air above the fire can cause a certain distortion and blurring of the view on the opposite side......"

So the basis of this theory is that what the eye sees is inextricably linked to light, and the elders, who have accumulated a lot of knowledge and wisdom, have keenly deduced the hidden connection from the words of the goblins. Eyes and light - this seems to be a matter of course but often overlooked.

"And then there's the 'mirage'. ”

The elder had already begun to have a certain degree of doubt about the knowledge he had in the past, why hadn't anyone carefully explored the origin of those illusions in the mirage!?

......

On the other hand, Gru's testing is also underway.

"Son, tell us a little about what you think about revenge. ”

"Revenge is a great thing!" replied the goblin, slightly excited, without thinking.

What kind of twisted and bizarre statement is this? Katrion doesn't even know what to say!

"Because the 'vengeful' people are always giving and don't get anything in return!" Looking at the increasingly strange expression of the elder opposite, Gru realized that he might have screwed up, "uh...... This is actually just one of the many jokes His Highness has made. ”

"Actually, the meaning of revenge is not so complicated, it is an act that even some beasts will have. After putting an end to his untimely joke, the goblin began to speak generously again, "This starts with the consequences of revenge...... It is precisely because the act of revenge itself exists among most intelligent beings that sane people tend to think about the possible retaliation and consequences of their actions before harming others, and think carefully about whether it is worth it for them to do so. It is this very common contrarian thinking and the widely accepted idea of 'revenge' that to some extent curb the causes of hatred. ”

"If people are afraid of the goblin tribe's revenge, then he will subconsciously resist his own behavior before harming the goblins...... Revenge itself is not of substantial benefit to those who have hatred in their hearts, but not before the next hatred arises. People tend to think more rationally before doing something like that, and of course, they can be blinded by hatred and become even more insane!"

"Revenge is an act of a private nature that complements the law in a society where the law is not yet perfect. It may sound crazy, but in some places some people are not afraid of the law, they are more afraid of simple revenge!"

"......" Catrion and his partner as an assistant examiner looked at each other in silence, and they tacitly felt that this was not an exam, but a process of understanding and examining what they had learned from different perspectives of other races and cultures.

- This day, as Udion had mentioned to André a month earlier. The two unassuming goblins used the knowledge they had forced into their heads for the past month to shock the leaders of the watchmen who were prejudiced against demons and once felt good about themselves.

Catharion remembered what he had said, "With the knowledge of these two goblins, it is more than enough to teach the younger generation of our elves." Yudeon is not exaggerating, the wisdom of that child of the abyss in the Emerald Valley is truly incomprehensible!"

In some respects, it was enough to teach us old fellows, and if these two unremarkable little ones had been born hundreds of years earlier, there might have been two more logistical leaders at the head of the coalition who were skilled in calculation and material allocation, and the role of these old fellows at that time was only to charge into battle—the elders remained silent while acquiescing.

The Children of the Abyss and his two students taught a very vivid lesson to these elders, who had lived for more than half a thousand years.
