Many people may be unfamiliar with the Habul calendar, but everyone knows about the famous Mayan calendar.

The Habu calendar is the Mayan solar calendar.

It consists of 18 months of 20 days per month, plus 5 days at the end of the year.

The first use of the Hab calendar began around 550 B.C. on a winter day.

The Habu calendar is the basis of the peasant calendar, and the names of the months are based on the seasons and agricultural events.

For example, the thirteenth month refers to the end of the rainy season.

The fourteenth month means the autumn ripening crops.

Sven Heding and July are quite difficult to explain, one is because of the differences in language and culture, Zhang Yishan needs to be translated and paraphrased.

The second reason is that July does not understand what kind of calendar the Mayan calendar is.

The long lecture waited for an hour to end.

He pointed to the writing on the wall, and told them in English that it was an ancient script, and that even he did not know what it meant.

The name of the Habu calendar month, as it is now known, was expressed in the Ya language of Jukatun during the colonial period.

The name is derived from the analysis of the phonetic elements of the Hab calendar characters in pre-Columbian Mayan inscriptions.

And the font on the inscription is almost the same as this kind of writing.

Especially for a few key month names, Sven Heding had seen Mayan inscriptions, so he consciously shouted out the word calendar.

This group of relief characters is obviously related to time, and July thought to herself, they are likely to fall into some kind of strange circle of time factors, even if they can go out now, it may not be the corresponding time and space.

"The Mayans considered the nameless days of the last five days of the Hab calendar to be a dangerous time." Sven Heding said worriedly, I'm afraid he also thought of something.

Zhang Yishan seemed to have adapted to the strange underground tombs, but she also said with a little worry: "The gate that separates the mortal world and the underworld has disappeared, and there is no restraint that can stop those evil gods from rising up calamities. ”

She had also read books about Mayan culture and had a vivid memory of the mysterious Hablica.

To ward off these evil spirits, the Mayans would perform rituals during these five days, according to custom, leaving their dwellings or brushing their hair.

Thus, these five days of the Hab calendar were considered by the Mayan inhabitants to be the most severe day of calamity.

After resting for a while, July's face looked much better, and politely borrowed a magnifying glass from Sven Heding, and continued to decipher the calendar text on the wall.

She didn't continue to talk to the three of them about the incident of "Empty Fox", let alone tell them, you will never be able to get out again, only stay in this time and space for the rest of your life.

Zhu Beichen's body is still lying quietly on the sand dunes, perhaps these mysterious ancient texts related to the calendar can explain the reason why he died half a year later.

If you look closely, you can see that there are many characters repeated on the small lettering on the relief, which may represent a group of numbers, which in turn indicate a special date.

A group of tadpole-shaped characters are staggered and surrounded, densely forming a chapter of more than 100,000 words, and July can't decipher this unfamiliar text for a while.

However, a peculiar phenomenon was discovered, that is, a group of words appeared very frequently, and according to the categories of modern Chinese, it was likely to be a group of nouns.

What does it stand for?

Four words? Zhang Yishan spit out the word lightly, and Qiyue and Ning Yun were both puzzled expressions, but they only touched Svenhe's heartstrings.

"Buried in the sand!"

Unexpectedly, some of the four people had heard of this word, and they didn't know where Zhang Yishan heard it.

"A legend that very few people have ever heard, the number of people in the formal archaeological community who know about the sand-buried ancient city is probably less than one percent."

"In the Tarim Basin, there is a legend about an ancient city buried in sand. It has been recorded in Xuanzang's "Records of the Western Regions of the Tang Dynasty". In the north of the present-day Hotan region, there was a city-state called Kora Loka. One day, a strangely dressed wandering monk appeared in the city-state, and he went about to make ends meet, except for a loyal elder who gave him food. In return, the monk said to the elder, "After I leave, a sand rain will fall from heaven to stop the old man from obliterating, and you must leave as soon as possible." ”

When the elder heard the news, he hurried to all parts of the city to report the news, but no one believed him. So the old man had to escape alone. In the middle of the night on the seventh day after the monk left, a sand rain fell from the sky and flooded the ancient city-state in an instant, and from then on the Sand Mountain became a sand mountain, sleeping forever in the Taklamakan Desert. ”

At this time, Ning Yun suddenly said: "What does the ancient city of sand burial have to do with the Habul calendar? ”

Her doubts were not entirely unreasonable, first of all, the time and place of the Mayan calendar were very different from those of Lop Nur, and it is even more surprising to assume that the calendar used during the existence of the city-state of Rauroka was the Hab calendar.

In short, the text recorded in the relief carvings in this side hall literally seems absurd and uninhibited, and it is completely different from the historical facts known today.

Zhang Yishan didn't argue, just quietly listened to Ning Yun finish her point of view before saying, "You listen to my analysis first." ”

The four characters of the ancient city buried in the sand are only passed down from the mouths of a few archaeologists and tomb robbers, although according to the ancient address marked in the Western Regions of the Tang Dynasty, it is roughly confirmed that it is in the Tarim Basin.

However, the location of the actual city of Raolaja has been debated over the years, and it is roughly established in the following locations.

The ancient city of Loulan is located in the lower reaches of the ancient Peacock River, on the west bank of Lop Nur, 320 kilometers away from the east of present-day Yuli County; Ancient Yixun City, located in the lower reaches of the ancient Milan River, 80 kilometers northeast of Ruoqiang County;

The ancient city of the end of the Han Dynasty is located in the lower reaches of the Cherchen River, 150 kilometers northeast of the county seat of the end of the Han Dynasty;

Niya ruins, located in the lower reaches of the Niya River, 150 kilometers north of Minfeng County;

Mazatag Gujung Fort is located in the middle reaches of the Hotan River, 200 kilometers north of present-day Hotan City.

In the process of Zhang Yishan's narration, the careful July has always observed the changes in Sven Heding's facial expression.

He is like a veteran who is proficient in psychology, and after experiencing the previous palpitations, he quickly buries his mind deeply.

"Determining the location of the ancient city is one thing, and someone has obtained more information about the ancient city. After years of sorting and collecting, it was found that even if the exact location of the ancient city was discovered, it was impossible to enter at all. ”

Zhang Yishan is a member of the scientific expedition team, and it seems reasonable to talk about the information about the sand-buried ancient city now. But she had also said before that very few people knew about the ancient city of Shaburi, and this time the goal of their scientific expedition was to consciously come to Lop Nur.

The first suspicious object is the ancient city of Loulan.

However, the target of their quest was the tomb of the sun.
