Primitive Tribe Adventure

"Well, you guys practice. Remember, I will test you tomorrow. If you can't use these ten basic numbers to show the number I reported, I will punish you."

When Fengyun saw that Mulanzhi and Fengbei were about to study, he announced that the study was over, but in order to consolidate and strengthen the learning effect, he also assigned them homework.

"The exam is going to be taken tomorrow. Brother Yun, your request is too high."

Feng Bei's face collapsed as soon as he heard that he was going to be assessed, and there was a faint look of fear and pleading in his eyes looking towards Feng Yun.

She is not unfamiliar with the assessment. Before Fengyun taught everyone to read, she had assigned various homework, and what she hated the most was doing homework.

Now that Fengyun was about to test her again, the good mood immediately disappeared.

"What's wrong, I'm scared? You thought it was simple just now. Didn't you urge me to teach faster? Why can't you say it now?"

Feng Yun knows Feng Bei very well, and when he sees an embarrassed expression, he decides to use the radical method on her.

Feng Bei is good at everything, but there is one thing that is not good, that is, it is relatively lazy, but for this, he still figured out a way to deal with it, that is to stimulate her.

Based on his observation and understanding of her, he knew that her self-esteem was very strong, and she would easily be hit by the radical technique, and she was relatively strong. Once she agreed, she would do her best to complete it.

"Who said I'm afraid. I'm not afraid."

Exactly as Feng Yun predicted, the aggressive method he used against Feng Bei worked again.

"Hard-mouthed. If you are not afraid, why did you look like that when I said that I was going to test you?"

Feng Yun deliberately put on a mocking expression.

Feng Bei's face blushed, but she still found an excuse for herself: "I'm really not afraid, I just don't think it's fair."

"Unfair? Where is it?"

"There are too many numbers. Who knows what numbers you will test tomorrow. If it is too difficult, wouldn't it be unfair to me and Sister Lanzhi. You only taught us for a little while."

"Okay. Now that you said that, I will determine the scope of the assessment. Tomorrow my assessment range will be a number between one and a hundred. There shouldn't be any difficulty in this way?"

"Brother Yun, this is what you said. Tomorrow will only test numbers ranging from one to a hundred?"

Before he could say anything, Feng Bei could not wait to respond, and stared at Feng Yun's eyes closely, as if he was afraid that he would repent.

"Don't worry. I don't count what I said, but I have already said ugly things before. If you fail to complete the assessment tomorrow, I will punish you and don't regret it."

As soon as Feng Yun finished speaking, he turned and walked away, and walked towards the paddy field in the distance. As he walked, he flipped his notebook to the front, and used charcoal to record under the numbered fields.

He taught Fengbei and Mulanzhi to learn to write Arabic numerals and their simple usage. Although it did not take too much time, the spring water of Shuang Lengquan was very effective. The growth of rainbow rice in some fields has changed significantly. It must be recorded in time.

Feng Yun's gaze was constantly moving in the fifty paddy fields. In the process, the charcoal in his hand moved quickly on the notebook, and the data quickly appeared in the blank spaces of the paper.

After writing down all the data to be recorded, Fengyun let out a long sigh. These raw data are very important. Once they are missed, they can only wait for the next time, and there is no guarantee that they are exactly the same.

Limited by the conditions, it is difficult to restore the same effect as this time when the rainbow rice is planted next time. Other than that, precise control of the water volume and flow rate into the paddy field is a big problem, not to mention the difference in rice varieties. .

But what makes Fengyun most inconvenient is his mastery of time.

Although through searching for memory, he knew the working principle of the clock, but under the current conditions, it is obviously unrealistic for him to make a clock that can work normally.

He usually uses the timing props he found in memory, such as drips and sundials, but these timing props are not very convenient to use, at least they cannot be carried with him.

Once he left the tribe, he would use other methods to time the clock, such as observing the changes in the position of the sun in the sky, not to mention that the error of this method is unpredictable.

So Fengyun invented an alternative timing method based on his own characteristics, which is to make himself a timing prop. The main step is to first record the interval between heartbeats through the timing props, and then count the number of heartbeats. Long time.

Although it is troublesome to count the number of heartbeats for a long time, Fengyun can still do it, but this does not mean that this timing method is perfect.

He does not have an accurate time to calibrate at any time. As time goes by, the error will be larger. After all, the speed of the heartbeat will be affected by various conditions, and there is no guarantee that the interval between its beatings will be consistent.

In addition, there is a problem, that is, once he sleeps, the counting of heartbeats will stop.

He became a totem warrior, especially after he was successfully promoted to a metamorphosis warrior, his energy far surpassed ordinary people, and he could not sleep for a long time, but being able to sleep for a long time did not mean that he did not need to sleep.

"We must make a timekeeping tool as accurate and convenient as a clock as soon as possible."

Feng Yun had told himself this more than once, but each time he gave up because of the immature conditions.

But this time his desire has become even stronger, because recording the growth of rainbow rice in fifty paddy fields has an unprecedented level of timekeeping requirements. It is difficult to meet the demand by relying on heartbeat timing alone.

"Would you like to send someone back to the tribe and bring some timing tools?"

Just when Feng Yun was hesitant to send someone back to the Jiao Tribe, he found that Feng Bei and Mulanzhi were approaching him together.

"What are they doing here?"

Feng Yun felt a little curious, he did not ask, but as soon as they approached him, he knew their intentions, and Feng Bei told him personally.

"Brother Yun, Sister Lanzhi and I don't understand the usage of these numbers. I want to ask you for advice."

It turns out that they encountered difficulties in their studies.

"Tell me, what do you not understand?"

Fengyun affirmed the learning attitude of Fengbei and Mulanzhi and expressed willingness to help them.

In doing so, besides sincerely hoping that they can truly master the usage of Arabic numerals, he actually has a little selfishness, that is, he wants them to help him.

The effect of the Shuang Leng Spring water is so good that it can make a significant change in the growth of the rainbow rice in a short period of time, and at the same time take care of fifty rice fields. Feng Yun felt that he was a little too busy.
