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

At the beginning of the 16th century, the Spaniards overthrew the Inca Empire and plundered a large number of gold and precious stones, and the Spanish commander Pizarro heard that all the gold of the Inca Empire was brought from Manoa, ruled by a chieftain named Patti, and that there was a mountain of gold and silver treasures.

Pizarro immediately organized an expedition to the Golden City, located deep in the jungle of the Amazon. Yet every step forward means fear and death in this vast primeval forest, with beasts and snakes, savage cannibal tribes, lost paths and threats, and a mysterious force that the expedition cannot explain. Expeditions were disappointed or unaccounted for, leaving Pizarro in awe.

So what kind of unpredictable events will the Torture Eagle and his party encounter when they go deep into the Amazon forest to find the Purple Clan this time? Perhaps, they will uncover the mysterious events that have plagued modern people for hundreds of years, or perhaps, they will all be buried in the mysterious primeval forest.

Since the 16th century, the salvage of the Golden Lake has not stopped. In 1545, a treasure hunt organized by the Spaniards retrieved hundreds of gold items from the shallow bottom of the lake in three months. In 1911, a British company dug a tunnel to drain the lake, but the sun quickly dried the thick mud into a dry slab, and when the British brought in drilling equipment from the UK, the lake was filled again, and the costly salvage failed.

In 1974, the Colombian government, fearing that the treasure in the lake would fall into the wrong hands, sent troops to protect the golden lake, and no one has been able to approach the treasure ever since. As a result, the mysterious Golden Lake has become an unsolvable mystery.

Will the Torture Eagle be able to find the location of the Golden Lake on this trip? Can we uncover the secrets of the Golden Lake from this series of strange legends? What secrets does Golden Lake hide? It is difficult to say that there is a mysterious space under the Golden Lake that is unknown to the world

Originally a small state in Cusco, the Inca did not expand until the 15th century, when Tupac Inca Yupanki expanded the Inca Empire to include Pasto in Colombia, as well as Tucumán in Argentina and the Mauré River in Chile. However, the struggle for the throne caused many civil wars by his heirs, which led to political unrest in the Inca Empire, and it was precisely because of this series of internal troubles that the later Spanish colonists had the opportunity to sow discord.

The Incas were the rulers of the largest empire in the Americas, and towards 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 1532, the expansion was forced to end hastily. By the time the Inca Empire fell, it had controlled a population of about 12,000 people, mostly Peruvian and Ecuadorian, but also a large number of Chilean, Bolivian, and Argentine.

The Incas called their territory tawantinsuyu, which is the Indian language, which means "four parts" in the language of the Incas. The land has a distinctly different topography and climate, not only a narrow coastal desert belt with rich irrigation canals; It also includes the towering peaks and fertile canyons of the Andes; The rainforests on the edge of the mountains stretch all the way to the east.

The ancestors of the Incas crossed the Bering Strait to the American continent about 11,000 years ago. For decades after the Incas arrived in the Americas, the inhabitants of Eurasia had little contact with the Incas. Over the course of their long history, the Indians created their own civilization in South America and established the Inca Empire, which was unprecedentedly vast.

On November 16, 1532, the day after the Spaniards arrived in Cajamarca, a messenger from Atahualpa arrived among the Spaniards. Pizarro said to the messenger: "Tell your sovereign that he is welcome." When and how to come, do as he wishes. Whatever way he comes, I will treat him as a friend and brother. I begged him to come quickly, for I longed to meet him. He will not be hurt or insulted in any way. ”

The Spaniard Francisco had heard of the Inca golden land before. So, in 1531, with the permission of the King of Spain, he took less than 200 men from the ports of Spain and began his journey to conquer an empire of six million people.

In fact, Francisco had already learned the secret of the civil war that was breaking out in the Incas through the conquest of the Aztecs, so he realized that this was the best time to conquer the Inca Empire. Outside Cajamarca, some Spanish officials met with the Inca ruler Atahualpa, who agreed to receive Francisco in the city.

The Spaniards soon moved into the abandoned town and soon settled into their places. When the Incas arrived, Francisco invited the atahualpa to dine together. To their surprise, Atahualpa not only accepted the invitation, but also claimed that his entourage would be unarmed.

When he arrived, a pastor tried to persuade him to become Christian. This is actually a signal of offense. Within 30 minutes, all 3,000 Incas were killed. An empire gradually declines because of the beginning of such an event.

The most famous site of today's Inca Empire is Machu Picchu, built between Machu and Huaina. The city of Cusco was destroyed by the Spanish colonial period, and only some architectural ruins remain, but a "dodecagonal stone" called "Hatum Rumiyok" has been preserved in the city, which archaeologists believe to be a tool for calculating the Inca calendar.

To this day, Machu Picchu remains the best place to get a glimpse of the ancient Inca civilization. At the same time, this mountain city also has many places that make modern people puzzled?

The Inca Empire's buildings, such as passages, canals, aqueducts, roads, inns, warehouses, and important facilities to improve the agricultural system, ensured the needs of a growing population while favoring the subjugation of other tribes. Although the Inca kings introduced some artistic and architectural patterns from the Cusco region, such as niches, irregular quadrangular doors and windows, and double-sided pillared doors, it should be affirmed that the culture of the Inca Empire brought together millennia traditions and reached its peak, as evidenced by the pottery art on display today.

The Inca Empire primarily believed in the sun god and considered itself to be a descendant of the sun god. Legend has it that the sun god sent one of his sons and daughters, Mancocapac and Maocchio, to teach the Inca people about the calendar, laws, etc. June 24 is the most important festival of the Inca Empire - the Festival of the Sun, at this time the Inca people would sacrifice their crops and livestock to the sun god, thanking the sun god for giving the earth sunlight every year, so that the animals can grow and the crops can be abundant.

The Aztecs of Mexican Central America, like the Incas, worshipped the sun god. This was not the case with the Maya in the Yucatan Peninsula, who worshipped Quetzalcoatl (but the Incas also had a Quetzalcoatl-like deity: Veracocha, the creator god). While the Mayans and Aztecs had a religious ritual of mass human sacrifice, the Incas did not, and the Incas would sacrifice their valuables, gold, or crops and livestock, to the gods, but would not sacrifice human lives.

According to archaeological excavations, the Inca Empire had bronze vessels and labor tools such as knives, sickles, and axes at that time, and its smelting and casting techniques were quite sophisticated. The Incas also had a well-developed agricultural irrigation system, stretching post roads, etc. Archaeologists generally agree that the Incas developed their building techniques, medicine, weaving and dyeing skills.

Curious is the record of the Inca knots, which have long been puzzled by scientists——— most early civilizations used hieroglyphs or images, but the Incas left behind cotton threads and knots.

Did the Inca Empire not have any form of writing? If this is the case, how will the country's vast amount of data and information be stored and transmitted? Are these ropes just abacus-like calculation tools or are they used to keep counts, or are they written in a three-dimensional space with a more complex form of writing than ——— notation?

The mysterious knot, known to the Incas as odds, was made from cotton, camel, or alpaca wool.

It is composed of thousands of secondary ropes strung on a main rope. The main rope is usually 0.5-0.7 cm in diameter, and there are many thinner secondary ropes tied to it, usually more than 100, sometimes as many as 2000. Each rope is tied with a dazzling string of knots, and a second or third layer of more rope hangs from the secondary rope, similar to the ancient Chinese used to protect against rain.

Of the 700 or so odd records found so far, most of them were knotted between 1400 and 1500 BC. However, some of them are only about 1,000 years old.

For a long time, scientists have refused to recognize the odd spectrum as a written document, and instead believe that the ropes are a device for preserving memory, that is, a personalized memory aid, at most a textile abacus, without any unified meaning. However, as the research deepened, some researchers increasingly doubted the correctness of this conclusion.

Harvard archaeologist Gerry Ulton and his colleague mathematician and weaving expert Kelly Bzheli used computers to analyze and study the various elements of these ropes, and found that the odd spectrum represented the way the numbers were recorded, and they succeeded in deciphering the first Inca script ——— the location of the Inca palace: the city of Pruchuko.

Qipu is a unique three-dimensional writing system, recording information about the 5,500-kilometer empire. Scientists created a corresponding database for each piece of "odd spectrum", recording in detail their various conditions: the size, length and color of the rope, the number of hanging spikes, the number of knots, the direction and number of rotations of each strand of rope, the age, etc., for the first time to systematically decompose and analyze the odd spectrum.

They want to find certain patterns through data analysis.

Of the 700 or so odd spectra in existence, scientists currently have a catalogue of 300 spectacles. When they searched the database for the commonalities of 21 odd knots found in 1956 in Pruchuco, an important political center of the Inca, they found a crucial mathematical connection—the knots on the secondary ropes of some odd scores were combined to coincide with the numbers on another, more complex spectrum. This suggests that the Odd Spectrum was used to record information about the empire, which was 5,500 kilometers wide.

Ulton says that there are usually three kinds of numbers represented by odd scores: the figure 8 knot represents 1; The long knot represents the numbers 2 to 9 according to the number of times it is twisted; Single knots represent 10, 100, and 1000, among others. Of course, 0 knots are simple, there is no need to tie knots at all, just leave an empty section of rope on the rope. A single string represents several numbers, which may be subtotals or sums. Suppose a rope has 4 single knots from top to bottom, 5 more single knots, and a long knot twisted twice, this rope will represent the number 452.

Each local accountant presents the sum of the accounts obtained from the subordinates in the form of knots on the odd spectrum, and aggregates these data on a main rope, and then passes it up layer by layer.

Such exchanges may have been used in the country's most important information records, including crop yields, revenue accounts of the State treasury, and other demographic, financial, and military-related data. After further in-depth research, they also succeeded in deciphering the first Inca script recorded in the "Odd Spectrum".

They argue that since different odd spectra represent data collected from different regions, a single knot on top of other knots could be a word that represents the place itself or financial data. One of the combinations of knots may indicate that the Inca palace was located in the city of Pruchuco, which is probably the first inscription to be recognized from the Inca genealogy.

Ulton said the discovery could help understand the textual information contained in those ropes. Urdon's previous research also found that the odd spectrum found in the mausoleum was also used as a calendar. There are 730 ropes hanging from 24 positions, indicating the months and days of the two years.

Urdon said: "It is fully believed that the odd spectrum was the three-dimensional writing system of the Incas. If they are just to help the owner remember the numbers, it is not necessarily that complicated. In Uldon's view, the writing system should include the type of material used (cotton or wool), the direction in which the rope is wound, and the direction of the knot (forward or backward).

Using the Odd Records, Inca rulers were able to transport food, manpower, and raw materials from Cuzburn, the capital of the Andes, to many other lower-tier cities, thanks to a vast system of roads and a system of government. The Inca "odd spectrum" belongs to the "epigram".

All the writing systems that we know of for everyday communication are written, drawn, or carved on a flat surface, and the odd spectrum is completely different from these characters, which are composed of a number of three-dimensional knots. （http：／／）。

If Urdon is right, then Qipu will be the only three-dimensional "text" in the world. In addition to this, it may also belong to one of the few "ideographic characters".

The characters in ideographic scripts are like numbers or dance symbols, indicating meaning, rather than pronunciation like English, such as Mayan script and Chinese. Although it may seem to us that communication with knotted ropes is very foreign, it has deep roots in Andean culture.

In Andean cultures, textiles, from fixed bags and tunics, to slingshot-thrown cannonballs and drawbridges, were "ways for people to exchange information and make tools."

Ulton said cracking the Odd Code could be a "huge potential resource for gaining the inside scoop" for understanding the Inca Empire, the largest and still enigmatic empire on Earth that ruled in the 16th century. Unfortunately, there is no other, more convincing evidence of the literal capabilities of the Odd Spectrum. An in-depth analysis of the Odd Spectrum will help uncover the details of his life, Urton said, and they hope that the Odd Spectrum will tell scientists whether it was a camel, laborer or other tribute. However, deciphering the information kept by the Incas in the "Strange Spectrum" requires the same effort as deciphering the ancient Egyptian hieroglyphs
