Chapter 743: Alternative Timekeeping

"Okay, practice hard. Remember, I will test you tomorrow. If you can't use these ten basic numbers to mark the numbers I reported, I will punish you."

Fengyun saw that Mulanzhi and Fengbei had almost finished their studies, so he announced that the study had come to an end, but in order to consolidate and strengthen the learning effect, he also assigned them homework.

"The exam is going to be tomorrow. Brother Yun, your requirements must be too high."

As soon as he heard about the assessment, Feng Bei's face immediately collapsed, and there was a hint of fear and pleading in his eyes looking at Feng Yun.

She is no stranger to assessments. When Fengyun taught everyone literacy before, she had assigned all kinds of homework, and what she hated most was doing homework.

Now hearing that Fengyun was going to conduct an assessment on her again, the good mood disappeared immediately.

"What's the matter, are you afraid? Didn't you think it was very simple just now and urged me to teach it quickly? Why are you saying it's impossible now?"

Feng Yun knew Feng Bei very well, seeing the embarrassed expression on her face, he decided to use aggressive methods on her.

Feng Bei is good at everything, but there is one bad thing, that is, he is lazy, but for this, he still found a way to deal with it, that is to stimulate her.

According to his observation and understanding of her, he knows that she has a strong self-esteem, and she will easily fall into the aggressive method, but she is relatively strong, and once she agrees, she will do her best to complete it.

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

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

"Stubborn. If you're not afraid, why did you have that expression when I said I was going to test you?"

Fengyun deliberately put on a mocking expression.

Feng Bei blushed, but she still found excuses for herself: "I'm really not afraid, I just think it's unfair."

"Unfair? Where is it unfair?"

"There are too many numbers. Who knows what numbers you will take the test tomorrow. If it is too difficult, it will be unfair to sister Lanzhi and me. You only taught us for a while."

"All right.

Now that you said that, let me confirm the scope of the assessment. Tomorrow my assessment range is a number between one and one hundred. There shouldn't be any difficulty in this way, right? "

"Brother Yun, that's what you said. Tomorrow, you will only test numbers between one and one hundred?"

Before the words fell, Feng Bei couldn't wait to respond, and stared into Feng Yun's eyes, as if he was afraid that he would go back on his word.

"Don't worry. What I say doesn't count, but I have already said something ugly. If you fail the assessment tomorrow, I will punish you. Don't go back on your word."

As soon as Fengyun finished speaking, he turned and walked away, walked towards the paddy fields in the distance, turned his notebook to the front as he walked, and wrote down the numbered fields with a charcoal pen.

He taught Fengbei and Mulanzhi to learn how to write Arabic numerals and their simple usage. Although it didn't take too much time, the spring water from the double cold springs was very effective, and the growth of rainbow rice in some fields had already changed significantly. It must be recorded in a timely manner.

Feng Yun's eyes kept moving among the fifty paddy fields. During this process, the charcoal pen in his hand moved quickly on the notebook, and data one by one quickly appeared in the blank space of the paper.

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

Due to limited conditions, it is difficult to restore the same effect as this time when planting rainbow rice next time. Among other things, it is a big problem to accurately control the amount and flow rate of water entering the paddy field, not to mention the difference in rice varieties. .

But the most inconvenient thing for Fengyun is the control of time.

Although he knew the working principle of the clock by searching his memory, it is obviously unrealistic for him to manufacture a clock that can operate normally under the current conditions.

He usually uses some timing props he found in his memory, such as drips and sundials, but these timing props are not very convenient to use, at least not portable.

Once he leaves the tribe, he will use other methods to time the time, such as observing the position of the sun in the sky. Not to mention that the error of this method cannot be grasped. Once it is cloudy, he will not be able to see the sun at all.

Therefore, according to its own characteristics, Fengyun invented an alternative timing method, that is, let yourself become a timing prop, mainly because the step is to first record the interval between heartbeats through the timing props, and then count the number of heartbeats to calculate how much time has passed. 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 doesn't have an accurate time to calibrate at any time. Over time, the error will be relatively large. After all, the speed of the heartbeat will be affected by various situations, and there is no guarantee that its beating interval will be consistent.

Also, there's the problem that counting heartbeats stops once he's asleep.

He became a totem warrior, especially after he was successfully promoted to a transformation warrior, his energy far surpassed that of ordinary people, and he could stay without sleep for a long time, but being able to stay without sleep for a long time did not mean that he did not need to sleep.

"It is necessary to create an accurate and convenient timing tool like a clock as soon as possible."

For this reason, Fengyun told himself this more than once, but every time he gave up because the conditions were not ripe.

But this time his desire became even stronger, because recording the growth of rainbow rice in fifty paddy fields required an unprecedented level of timing, and it was already difficult to meet the demand only by heartbeat timing.

"Should we send someone back to the tribe and bring some timing tools?"

Just when Fengyun was hesitating whether to send someone back to the Huojiao tribe, he found Fengbei and Mulanzhi walking towards him together.

"What are they doing here?"

Feng Yun felt a little curious, he didn't ask any questions, but as soon as they approached him, he knew their intentions, Feng Bei told him personally.

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

It turned out that they encountered difficulties in their studies.

"Tell me, what is it that you don't understand?"

Fengyun affirmed Fengbei and Mulanzhi's learning attitude and expressed willingness to help them.

In doing this, besides sincerely hoping that they could truly master the usage of Arabic numerals, he actually had a little selfishness in mind, that is, he wanted them to help him.

The effect of the double cold spring water is so good that it can significantly change the growth of the rainbow rice in a very short period of time. Fengyun feels that he is a bit too busy to take care of fifty rice fields at the same time.
