After Ye Feng finished speaking, his right hand stretched out his index finger and middle finger, carrying the pulse on his left wrist, and he wanted to use this method to calculate the time. Generally, the pulse of a normal adult is 60-80 times per minute in a quiet state, and this question is timed for five minutes, that is to say, Ye Feng only needs to write down the pulse of about 140.

Although this timekeeping method is very inaccurate, it is also helpless in the absence of any timekeeping tools in this era.

…………

This question came out of Ye Feng's mouth, and the crowd was full of mourning. Ye Feng coughed lightly, and the people stopped and put away their noisy thoughts.

Just when everyone was arguing, a man stood up from the phalanx on the left, came to the stone pier on the right, and looked at everyone with a smile on his face.

This person is the root of the tree, seeing his smug appearance, Ye Feng didn't secretly compare his middle finger to him.

Since you can't resist, let's enjoy it. The primitive people frowned and thought about the math problems that would be easy for elementary school students in later generations, and their faces were as if they were constipated, and they made very painful expressions.

I saw that someone broke his fingers, and when he saw that ten fingers were not enough, he hurriedly took off his shoes, emitting a stinky smell, and the people next to him hurriedly covered their noses and cast resentful glances. But this person didn't care about this, and hurriedly counted with his toes, but found that it was still not enough, and suddenly his eyes widened, and he scratched his hair in distress, at a loss.

And next to him, there was a man with dull eyes, the smell of his stinky feet as if it didn't exist, and he ignored him directly. He slowly raised his head, looking at the clear blue sky with confused eyes, and he didn't know whether he was thinking or praying that the gods would rain heavily so that this exam would not end.

What's more, knowing that he couldn't get through, he dozed off directly, and the snoring sound was almost earth-shattering.

After a long time, a group of people finally left their seats and sat down on the stone bench on the right under the envious gaze of the people. And this group of people is the mischievous bear children of the tribe.

The adults, seeing a group of children complete the problem faster than themselves, sat on the throne on the right. All of them blushed with shame, and secretly said that they were not even as good as children.

"Sister, sister! What are they doing sitting together? In the tribal cave, Xiao Zhengtai Ergou pointed to the clansmen outside and asked Chu Yun.

Chu Yun touched Ergou's head and said with a smile: "They're taking the exam!" ”

"What is an exam?"

"The exam is to test what you know. so that the teacher can ...... Oh, it's that the person who taught you knows what you've learned and what you've not, and he can teach you what you haven't learned again. ”

Ergou looked confused and asked, "What is knowledge?" ”

Chu Yun patiently explained: "Knowledge is the knowledge and experience that people gain in practice. That is, what hunters should pay attention to when hunting, what skills they have, and how much prey they should hunt in a day. The women knew how much they had collected when they were collecting, and how to be just and fair when distributing food to their tribesmen required knowledge. ”

Ergou nodded knowingly and said, "But why do you want to learn knowledge?" Our tribe didn't have knowledge, but we still lived well. ”

Chu Yun: "............"

In the examination room, the people who sat at the end of the long-eared ears moved slightly, with a smug smile on their faces, and then got up and strode towards the stone bench on the right.

Before he could sit down, a loud voice suddenly sounded, startling him. I just listened to the voice and said, "I know! I finally got it! I know the final answer! Hahaha! ”

Long Ear took a closer look and found that this person was the leader of the hunting team - Liu Junting.

On the podium, Ye Feng saw that this kid was messy again, and couldn't help but be angry, and hurriedly shouted: "Liu Junting! Shut up for me, this is the exam room, have you forgotten the rules of keeping quiet, and when you think of the answer, roll me to the stone bench on the right! ”

Li Junting's head shrank and nodded desperately. Then he bent over, fell to the ground, and really "rolled" onto the stone bench.

If he hadn't had to count the number of pulses, Ye Feng would have to hold his forehead with his hand, and he didn't know what was going on in his brain at the beginning, so he made him the leader of the hunting team.

Liu Junting sat next to Chang'er, and seeing that he really had nothing to do, he beckoned to Chang'er and said, "Hey, Chang'er, your speed is so fast, you sat here so quickly." ”

Chang Er waved his hand humbly and said, "You're not bad, you thought of the answer just when the bamboo basket had a headache." As soon as he finished saying this, Chang Er said cautiously: "I didn't expect the answer to be correct?" ”

Liu Junting's face flickered, he was slightly dissatisfied because of Chang'er's suspicion of himself, and said angrily: "It must be correct, I am the leader of the hunting team, and we often do it in the hunting group when I shoot down the birds in the trees, and I am the most experienced in this problem." ”

Chang'er nodded hurriedly, and hurriedly whispered: "That's good, that's good, that's really good, so I can pass it too." ”

"Oh?" Liu Junting was confused by this sentence.

Long Ear pointed to his ear and said with a smile: "You have forgotten my extraordinary hearing, as long as Ye Feng comes to ask for your answer, I can hear it no matter how far away, and when the time comes........." Long Ear's face showed a smile that you understand.

Liu Junting hurriedly gave him a thumbs up (this was also learned from Ye Feng), revealing a look of you know me and I know the heavens and the earth.

Ye Feng heard the two of them talking about it, and coughed lightly: "Ahem, cough, pay attention to the discipline in the examination room!" ”

"Time is over! Now stop sitting to the right! Ye Feng's words threw a thunderbolt on the sunny day, and everyone who was still sitting on the right side was shocked, and then let out a distressed wail. And the dozen or so sparse enemies sitting on the right looked at the distressed expressions of those people with a smile, showing a relaxed and comfortable expression.

Ye Feng took out a roll of animal skins and said, "Now let's start counting the answers!" ”

As soon as this sentence came out, more than a dozen people sitting on the right couldn't help but straighten up, staring at Ye Feng who was walking slowly, and their hearts were up and down. I am afraid that I will be ridiculed by others if I think that the answer is wrong.

"Name, plus your answer!" Ye Feng leaned his ear to this person and said.

This could be muttered in his ear, Ye Feng nodded, and spit out a word: "Pass!" Then write the man's name on the skin, and put a big tick on it.

Then he did the same on more than a dozen other people, and after a while, he came to Liu Junting's side.

"It's coming, it's coming!" Seeing Ye Feng approaching, Liu Junting sat up straight, silently recited his answer in his heart, and after confirming that it was correct, he confidently waited for Ye Feng's inquiry.
