Chen Jian would call Xuan Mingzi ahead, and it was obvious that Chen Jian felt that Xuan Mingzi was the easiest to understand what he said.

Sure enough, after hearing Chen Jian's words, Xuan Mingzi nodded silently and said, "The number of changes in the moon phase!"

Chen Jian also nodded.

Wang Fugui said at this time: "What is the number of changes in the moon phase?"

"The number of changes in the moon phase is the cycle of changes in the moon." Chen Jian said with a smile: "It is the lunar calendar we use, the lunar calendar!"

"Hi, I've talked about the lunar calendar a long time ago, but the lunar calendar won't work." Wang Fugui said immediately.

Chen Jian chuckled and shook his head, saying, "The ancients called a cycle of the moon full and waning, and the day when the moon was completely missing was called the new day, which was the first day of the lunar calendar! The day with the most round moon was called the day of the sun, which was the fifteenth or sixteenth of the lunar calendar. From the new year to the sun, it is the first half of the moon, and from the new year to the new year, it is the second half of the moon, from the new year to the new year, it is the month of the lunar calendar."

There is no doubt that Chen Jian said this to everyone, and it is also explaining the relationship between the changes in the moon phase and the lunar calendar.

"There is a saying that the moon is 15th and 16th round!" Xuan Mingzi said at this time: "It originated from the changes in the phases of the moon."

After Xuan Mingzi said this, he looked at Chen Jian and signaled Chen Jian to continue speaking because Chen Jian had not reached the point yet.

Chen Jian continued: "The cycle of the phase change of the moon is called the lunar month, which is what we often call the lunar calendar. Therefore, the number of changes in the moon refers to the lunar month, or the number of days in the lunar calendar. Observations show that the length of the lunar month is not fixed, sometimes it lasts more than 29 days and more than 19 hours, and sometimes it is only 29 days and more than 6 hours. Its average length is twenty-nine days, twelve hours, forty-four minutes,03 seconds."

Chen Jian then said: "The lunar calendar is actually the moon calendar, but we all know that the number of days in each month of the lunar calendar is not necessarily the same. Some months are twenty-nine days, some are thirty days, and the lunar calendar has leap months. This is actually because the Gregorian calendar is the solar calendar. It does not consider the changes in the moon's relationship. It only considers the length of the time when the earth orbits around the sun, that is, a return year. The number of days in each month of the lunar calendar is different. There is also the setting of the leap month, which is caused by the Yin-Yang calendar. The Yin-Yang calendar is set to coordinate the contradiction between the Return Year and the lunar calendar, and prevent the lunar calendar year and the Return Year, that is, the four seasons are out of touch!"

After a pause, Chen Jian pointed to the steps under his feet and said, "So, Taoist Master Xuan Mingzi and I don't use the lunar calendar days to talk about these steps, but use the number of changes in the moon phase!"

Hearing Chen Jian's words, Xuan Mingzi nodded with a smile, but the others showed a sudden enlightenment. Finally, they understood why Chen Jian said that these steps were a proof, which vaguely confirmed that this place was indeed a place of sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrific

At the same time, I also understand that the number of changes in the moon phase is still somewhat different from the lunar calendar, because the changes in the moon phase are always the same. Although the lunar calendar is the moon calendar, it has more changes because it has become a calendar that records the year, month and day.

In this way, the number of these steps is completely clear at a glance when only the number of days in the moon phase change period, that is, the number of moon phase changes.

The number of changes in the moon phase is thirty, and the total number of these steps is also thirty.

It can be seen that each step corresponds to one day in the moon phase change cycle, that is, one-third of the number of moon phase changes.

The most important thing is that there are twenty-four hours a day. Even if the ancients divided it into twelve hours, the twenty-four hours a day will not change, and there will be no conflicts, because one hour is two hours.

The last day of the moon phase change cycle is actually not enough for twenty-four hours a day. Sometimes it is more than nineteen hours, and sometimes it is only more than six hours. The average number is twelve hours, forty-four minutes, and three seconds. This average number is basically in the middle of twenty-four hours a day.

The last step, that is, the thirtyth step, is shortened by half the width than the twenty-nine steps above. If the width of the twenty-nine steps above represents twenty-four hours a day and the last step is shortened by half the width, it just represents half the time, that is, twelve hours. Not to mention the number of days in the moon phase change cycle, even the duration of the last day is averaged, which is expressed in the form of shortening the width of the step by half.

There is only one final conclusion, and these steps perfectly correspond to the changes in the moon phase!

This is an underground sacrificial place. Sacrifice requires sincerity and is a very ritualistic act. It will never be casual. There are only thirty steps, and the last step is shortened by half. It will definitely not be done casually, but it has its own representative meaning. These meanings increase the sense of ritual for sacrificial acts!

"Continue to move forward?" Xiao Yurou asked at this time, looking at the passage ahead.

Chen Jian nodded and was about to walk forward, but Wang Fugui reached out to stop him.

After being stopped by Wang Fugui, Chen Jian naturally looked at Wang Fugui.

Not only Chen Jian, but everyone also looked at Wang Fugui.

Wang Fugui said nothing, but looked a little anxious when he scratched his head, and said, "Wait first, let me slap my forehead and say what should I say!"

"Don't worry, think about it slowly!" Chen Jian said.

Hearing Chen Jian's words, Xiao Yurou looked at Chen Jian in confusion.

Chen Jian slowly shook his head at Xiao Yurou, without explaining anything to Xiao Yurou.

Although Wang Fugui was proficient in mechanical skills, it can be seen from the information that he had not attended any school, that is, he did not have a high degree of education. Many of the people in his era were illiterate.

In other words, Wang Fugui is stupid and must have thought of something at this time, but he cannot say it accurately.

Therefore, Chen Jian said there was no hurry and let him think slowly.

If Wang Fugui had been to school, even if he had only a junior high school degree or even a fifth grade elementary school degree, he would not be likely to have such a situation that he didn't know what to say.

Language organization ability can be learned.

The higher a person's knowledge, the higher his language organization ability.

"What's wrong!" Wang Fugui thought for a while before saying these three words, then looked at Chen Jian and said, "You don't understand what you said, you just know the lunar calendar and use the lunar calendar to calculate your days all day!"

Hearing Wang Fugui's words, Chen Jian nodded as he looked at Wang Fugui.

Wang Fugui continued: "Even the steps here is so particular. The passage in front makes me feel something is wrong, so let me think about it again!"
Chapter completed!
