In ancient times, there was an Inca Empire centered on Peru in South America, which was very powerful. All the palaces and temples in the capital were decorated with a large amount of gold and silver, magnificent and dazzling.

In the early 16th century, the Spanish overthrew the Inca Empire and plundered a large number of gold and gems. Spanish commander Pisaro heard that the gold of the Inca Empire was all brought from Manoa, a chief named Patti, and there were mountains of gold, silver and treasures.

Pisaro immediately organized an expedition to the Golden City, located deep in the dense Amazon forest. However, in this vast and primitive forest, every step forward means fear and death. There are beasts and venomous snakes, barbaric cannibal tribes, lost roads and threats, and a mysterious force that the expedition cannot explain. The expedition teams either returned in disappointment or were missing, which made Pisaro be afraid when he looked at this forest from afar.

Then what kind of unpredictable events will Xing Ying and his group go deep into the Amazon forest to look for the Zi tribe? Perhaps, they will uncover the mysterious events that have plagued modern people for hundreds of years, and perhaps, they will all be buried in that mysterious primeval forest.

Since the 16th century, the salvage of the Golden Lake has never stopped. In 1545, a treasure hunt team organized by the Spaniards salvaged hundreds of gold items from the shallower lake bottom in a month. In 1911, a British company dug an authentic tunnel and drained the lake water, but the sun quickly dried the thick mud into dry and hard mud. When the British transported the drilling equipment from Britain, the lake was filled with lake water again, and this costly salvage also failed.

In 1974, the Colombian government was worried that the treasures in the lake would fall into the hands of others, so it dispatched troops to protect the Golden Lake. No one could get close to this batch of treasures ever since. Therefore, the mysterious Golden Lake became an unresolved mystery.

Can Xing Ying and others find the location of the Golden Lake during this trip? Can they uncover the secrets of the Golden Lake from this series of strange legends? What unknown secrets are hidden in the Golden Lake? It is hard to say that there is a mysterious space under the Golden Lake that is unknown to the world...

The Inca was originally just a small country in Cusco, and its main territory expansion did not begin until the 15th century. Tupac Inca Yupanki expanded the territory of the Inca Empire to Pasto in Colombia, as well as Tucumen in Argentina and the Maure River in Chile. However, his descendants caused many civil wars due to the battle for the throne, which led to the political unrest of the Inca Empire. It was precisely because of this series of internal troubles that gave the later Spanish colonists the opportunity to sow discord.

The Incas were the rulers of the largest empire in the United States. At the end of the 14th century, the Inca Empire began to expand from the Cusco region of the Southern Andes in South America. But when the Spanish led by Francisco began to invade in 15 years, the expansion was forced to end hastily. By the time the Inca Empire was destroyed, it had already controlled about 10 million people, mostly Peruvian and Ecuadorian, and a large part of Chilean, Bolivian and Argentinians.

The Incas called their territory Taantinsuyu, which is an Indian language. In the Inca language, it means "four parts". This land has obviously different terrain and climate. It not only has a narrow coastal desert belt that runs through rich irrigation canals; it also includes towering peaks and fertile gorges in the Andes; the tropical rainforest on the edge of the mountain range extends to the east.

The ancestors of the Incas crossed the Bering Strait about 11,000 years ago to the American continent. In the decades after the Incas arrived in the Americas, the residents of Eurasia had little contact with the Incas. Over the long history, the Indians created their own civilization in South America and established the Inca Empire with unprecedented territory.

On November 16, 2015, the day after the Spanish arrived in Cajamaca, a messenger from Atavalpa came to the Spanish. Pizarro said to the messenger: "Please tell the monarch of your country and welcome him to come. As for when and how to come, you can do whatever he wants. No matter what way he does, I will treat him as a friend and brother. I beg him to come quickly, because I long to meet him. He will not be hurt or insulted."

The Spanish Francisco had heard of the Inca golden land before. So, in 151, with the permission of the Spanish king, he took less than 00 people to sail from the Spanish port and empire with a population of six million.

In fact, Francisco had obtained the secret of the civil war breaking out in the Incas by conquering the Aztecs, so he realized that this was the best time to conquer the Inca Empire. Outside the city of Cajamarca, some Spanish officials met Atahuaalpa, the Inca ruler, and Atahuaalpa agreed to meet Francisco in the city.

The Spaniards soon entered the abandoned town and soon took their place. When the Incas arrived, Francisco invited Atahuaalpa to have a meal together. To their surprise, Atahuaalpa not only accepted the invitation, but also claimed that his entourage would not only carry weapons.

When he arrived, a pastor tried to persuade him to believe in Christianity. This was actually a signal of attack. Within 0 minutes, all 000 Incas were killed. An empire gradually declined because of the beginning of such an incident.

The most famous ruins of the Inca Empire today are Machu Picchu, which was built between Machu Peak and Huainna Peak. Due to the destruction of the Spanish colonial period, only some architectural ruins remain, but a "twelve-cornered stone" is preserved in the city, called "Hatumrumiyok". Archaeologists believe it is a kind of Inca calendar calculation tool.

To this day, Machu Picchu is still the best place to understand the ancient Inca civilization. At the same time, there are many places in this mountain city that puzzle modern people?

The Inca Empire's buildings such as passages, canals, waterways, aqueducts, roads, inns, warehouses and important facilities to improve the agricultural system ensured the growing population demand while also benefiting the surrender of other tribes. Although the Inca Kings implemented some artistic and architectural models from the Cusco area, such as niches, irregular quadrilateral doors and windows, and double-sided sillar doors, it should be confirmed that the culture of the Inca Empire has summed up thousands of years of tradition and reached its peak, as evidenced by the pottery art exhibited today.

The Inca Empire mainly believed in the Sun God and considered itself the descendant of the Sun God. Legend has it that the Sun God sent his sons, Mankokapak and Maoke to teach the Inca people the calendar, law, etc. June 4th of each year is the most important festival of the Inca Empire - the Sun Festival. At this time, the Inca people will sacrifice their crops and livestock to the Sun God. Thanks to the Sun God for giving sunlight to the earth every year so that animals can grow and crops can be abundant.

The Aztecs in Mexican Mexico, like the Incas, worship the sun god. However, the Mayans in Yucatan Peninsula were not the case. The Mayans worshiped the feathered snake god (but the Incas also had gods similar to the feathered snake god: the creation god - Verakocha). The Mayans and the Aztecs had religious rituals for large-scale sacrifices of living people, but the Incas did not. The Incas would offer their precious items, gold, or crops and livestock to the gods, but would not sacrifice human life.

According to archaeological excavations, the Inca Empire at that time had bronze vessels and labor tools such as knives, sickles, and axes, and its smelting and casting technology was quite exquisite. The Incas also had developed agricultural irrigation systems and continuous post roads. Most archaeologists believed that the Incas' construction technology, medicine, weaving and dyeing skills were quite developed.

What is strange is the Inca knot record. Scientists have always been confused about these knots - most civilizations used hieroglyphs or images in the early days, but what the Incas left behind were cotton thread and knots.

Is there no way to write in the Inca Empire? If so, how will the country's large amount of data and information be stored and transmitted? These rope joints are just calculation tools like abacus or are used to record numbers, or have a more complex writing form than the form of counting - the three-dimensional space writing method of ropes?

The mysterious knot was called the Incas and was made of cotton thread, camel or alpaca yarn thread.

It is composed of thousands of sub-ropes strung on a main rope. The main rope is usually 0.5-0.7 cm in diameter, and there are many thin sub-ropes tied on it, usually more than 100, and sometimes even as many as 000. Each sub-rope has a dazzling string of knots, and the second or third layer of more ropes are hung on the sub-rope. The braided form is similar to the raincoat used by ancient Chinese people to prevent rain.

Among the 700 spectras discovered so far, most of them are knots tied between 1400 and 1500 BC. However, some of them have a history of only about 1,000 years.

Scientists have always refused to admit that the miracle spectrum is a written document, and believe that these ropes are a device for preserving memory, that is, a personal memory auxiliary tool, at most a textile abacus without any unified meaning. However, as the research deepens, some research scholars increasingly doubt the correctness of this conclusion.

Harvard University archaeologist Gerry Ulton and his colleagues, mathematician and weaving expert Kelly Brzeli conducted long-term analysis and research on various elements of these ropes through computers. The results showed that the numerical recording method represented by the strange spectrum and successfully deciphered the first Inca text, the location of the Inca palace: Pluchuko.

The strange spectrum is a unique three-dimensional writing system that records the information of the 5,500-kilometer empire. Scientists have created a corresponding database for each "strange spectrum", recording their various situations in detail: the size, length and color of the rope, the number of hanging spikes, the number of knots, the rotation direction and number of each rope, and the age, etc. The first time, the strange spectrum was systematically decomposed and analyzed.

They hope to find certain rules through data analysis.

Among the 700 existing spectrals, scientists currently have a catalog of 00 spectrals. When they searched the database for common points of a spectral knot found in Pluchuko, an important political center in the Incas, in 1956, the results were shocking. They discovered a crucial mathematical connection - when the knots on the sub-strings of some spectrals are combined, they happened to be the same as the numbers on another more complex spectral. This shows that spectrals were used to record information about this empire with a 5,500-kilometer-wide width.

Ulton said that there are usually three types of numbers represented by the strange spectrum: 8-character knots represent 1; long knots represent 9 in sequence according to the number of twists; single knots represent 10, 100 and 1000, etc. 0 knots are of course simple, and there is no need to make joints at all, just leave a piece of rope on the rope. Single ropes represent several numbers, which may be subtotals or sums. Suppose a rope has 4 single knots strings from top to bottom, and a 5 single knot string, and a long knot twisted twice, this rope will represent the number 45.

Each local accountant will express the sum of accounts obtained from the subordinates on the strange spectrum in the form of a knot, and summarize the data on a main rope and then hand it over layer by layer.

This kind of exchange may have been used in the most important information records of the country, including crop yields, treasury income accounts, and other population, finance and military-related data. After further in-depth research, they also successfully deciphered the first Inca text recorded in the "strange spectrum".

They believe that since different spectrals represent data collected from different regions, a single knot on top of other knots may be a word, indicating the place itself or financial data. Among them, a combination pattern of knots may indicate that the location of the Inca palace is Pluchuko, which is likely the first word recognized from the Inca spectrals.

Ulton said the discovery helped to understand the textual information contained in those ropes. Previous research by Ulton also found that the spectacles found in the mausoleum were also used as calendars. 70 ropes were hung in four positions to represent the months and days of the two years.

Ulton said: "It can be fully believed that "Strange Score" is the three-dimensional writing system of the Incas. If they are just to help the owner remember the numbers, it is not necessary to be so complicated." In Ulton's view, the Strange Score writing system should include: the type of material used (cotton or yarn), the direction of the rope wrapping and the direction of the knot (forward or backward), etc.

Using the strange spectrum records, the Inca rulers could transport food, manpower and raw materials from the capital of the Andes from Cusbon, the capital of the Andes to many other lower cities. The "strange spectrum" of the Incas belongs to the "emotional text".

All the text systems we know about for daily communication are written, drawn or engraved on a plane, and the strange spectral is completely different from these texts and is composed of some three-dimensional knots.

If Ulton and the others were right, then the strange spectrum would be the only three-dimensional "text" in the world. In addition, it may also belong to a few "emotional texts".

The characters in esoteric characters are like numbers or dance symbols, indicating meaning, rather than pronunciation like English, such as Mayan characters and Chinese. Although in our opinion, using knots for communication is very unfamiliar, it has deep roots in Andean culture.

In Andean culture, textiles range from fixed-style bags and tunic jackets to shells thrown by slingshots and suspension bridges are all ways to "people exchange various information and manufacturing tools."

Ulton said that cracking the secret code of the strange spectral may be a "huge potential resource for gaining inside information" for understanding the largest Inca Empire that ruled the earth in the 16th century, but unfortunately, there is no other more convincing evidence to prove the textual function of the "strange spectral". Ulton said that in-depth analysis of the strange spectral will help uncover the details of its life, and they hope that based on the strange spectral, it can tell scientists whether this is a camel, labor or other tribute. However, to crack the information preserved by the Incas in the "strange spectral", it requires the same effort as interpreting ancient Egyptian hieroglyphs...
