"Gold is undoubtedly a kind of energy source, but we humans have not discovered its specific role! I would also say that there is one more mineral that can connect Africa and the Americas – tin ore!

Tin ore was always used up quickly in the hands of the Sumerians, so where was the subsequent source? Some Sumerian texts mention that there are two tin mountains in the distant land, and we do not yet know where they are.

But modern people know that in the southeast of La Paz, the capital of Bolivia, to the east of Lake Poo. It was from this place that ancient people collected tin ore, and it continues to this day!

At the same time, the British scholar Bosnansky discovered a pre-Inca mine six miles from Tijuanaco, and the strongest evidence shows that this is where the Sumerians mined tin in the first place. ”

In just a few words, the shock that brought Hu Xiaodao and Jennifer was simply incomparable.

"Does this mean that the Sumerians were free to travel between the two continents to gather minerals?" Jennifer said with some surprise.

You must know that even modern people can't use transportation so easily, how huge was the transportation network of ancient people?

At this time, Hu Xiaodao appeared in his mind an underground passage - the Mexican underground tunnel!

In the 17th century, a Spanish missionary discovered an underground tunnel in Guatemala, Central America. It is located beneath a residential area in Puchota and appears to be connected to the underground tunnels of Cusco, South America.

After that, a Jew named Stephens discovered another underground tunnel from western Guatemala to Mexico. Later, an underground tunnel was discovered in Cusco, Peru.

It has direct access to Lima to the north and Bolivia to the south. On the map, it is located beneath the Andes Mountains and may be more than 1,000 kilometers long.

In order to better protect this ancient civilization site, the Peruvian government reclosed the entrances to these discovered tunnels, considering that with the current state of technology, it was not yet able to develop and protect it. It is also a UNESCO World Heritage Site.

The Peruvian government had just closed the mouth of the discovered tunnel, and then the even more startling news came from the valley of the northern Peruvian coast when archaeologists had found a large number of works of art and two pyramid-shaped structures in an ancient burial chamber there.

According to preliminary research, it is a tomb of a ruler, and the artwork inside includes a golden crown, a royal scepter, a golden peanut, a delicate necklace and exquisite pottery. Many gold and silver products are inlaid with delicate jade and dazzling gemstones.

When these gleaming treasures are unveiled to the world, many people can't believe they come from underground. After these treasures were excavated, they were brought to the United States for exhibition.

The reason for this is that the Peruvian government lacks money and the technology and funds needed to preserve these treasures, so it is not known when these treasures will be returned.

In fact, people may not know that deep underneath the South American continent, there is a larger, huge tunnel system that stretches for thousands of kilometers.

This massive tunnel was built in June 1965 by Argentine archaeologist Juan Brown. Moritz stumbled upon it in Ecuador, and he was silent for three years before it was revealed to the world.

After surveying hundreds of kilometers of tunnels and discovering many artifacts, it was not until 1969 that Moritz asked to meet with the President of Ecuador to report to him about the tunnels.

In July 1969, Juan? Moritz obtained a notarized certificate authorized by the Ecuadorian state certifying that he had ownership of the Ecuadorian underground caves, subject to the control of the Ecuadorian national government.

Located 240 metres underground, the tunnel is part of an extremely large and complex tunnel system, estimated to be more than 4,000 kilometers long, and it is not yet known where it ultimately leads.

The secret entrance to the tunnel is located in the Guaraquiza-San Antonio-Yaupi triangle in the province of Morona – Santiago. Only a few hundred kilometres in Ecuador and Peru have been surveyed and measured.

The entrance to the tunnel is now guarded day and night by an uncivilized Indian tribe.

German writer von? Deniken had entered the tunnel with Moritz himself.

In the tunnels, he saw wide, straight passages and walls, many delicate rock openings and gates, smooth roofs and halls of more than 20,000 square meters, and many ventilation shafts that appeared at intervals with an average length of 1.8 to 3.1 meters and a width of 80 centimeters.

The grandeur and grandeur of the tunnel project stunned even the writer, who was known for his bold imagination. He has no doubt that this is our biggest project in the world, and the biggest and most difficult mystery in the world.

In this tunnel, there are countless extremely precious ancient relics of great cultural and historical value to mankind.

Shortly after entering from the entrance to the tunnel discovered by Moritz there is a giant hall of 140 meters × 150 meters, the size of an airplane hangar in our most advanced large airport.

In the center of the hall is a table and seven chairs. These tables and chairs are neither stone nor wood, they are as hard as metal, but they look like they are made of man-made materials.

In this tunnel, there are countless extremely precious ancient relics of great cultural and historical value to mankind.

There are also many animal statues in the hall, such as monitor lizards, elephants, lions, crocodiles, jaguars, camels, bears, apes, bison, wolves, snails and crabs. Some of these animals, such as elephants, lions and camels, are not native to the Americas.

What's even more surprising is that a dinosaur is carved on a stone slab 53 cm long and 29 cm wide in the tunnel! Dinosaurs became extinct 64 million years ago, and all the knowledge of dinosaurs today comes from the study of dinosaur fossils.

So how did ancient humans know what dinosaurs looked like unless they were aliens?

A 12-centimeter-high, 6-centimeter-wide stone-made amulet was also found in the tunnel, identified as a relic from 9,000 to 4,000 BC.

On the back of it was a half-curved moon and a radiant sun, and on the front was a small creature, the child holding the moon in his right hand and the sun in his left hand, and he was still standing on a round sphere!

All of the above has evidence to be found, combined with Professor Hudson's previous analysis, this mystery that has plagued mankind for nearly a hundred years has finally been solved.

However, Professor Hudson said that the data will not be made public, after all, although these mysteries can be solved one by one, no one will believe them at all.

For example, the 140-meter ×-150-meter hall now seems to be a tin ore warehouse at that time.

There are also statues of elephants, lions, and camels, which may have been brought to the Americas by aliens after discovering them.

After listening to the professor's explanation, Hu Xiaodao and Jennifer nodded thoughtfully, and Nagu also smiled innocently! 210
