Half a month later, on the afternoon of October 19, Tuxtla Gutierrez, the capital of Chiapas, in southeastern Mexico.

A civilian piston propeller took off and headed straight south into the Chiapas jungle beneath the Kokhrita Mountains.

There were no guides or locals in the cabin, just a small knife with a hiking bag on his back and a live broadcaster on his head.

This time he traveled thousands of miles to this place where the Indians gathered, and did not hire local guides, and he said that he was going on foot expeditions, but in fact he ......

His purpose is to "treasure hunting", to find the underground world left by the legendary Mayans, which runs through the whole of South and North America, with a total length of more than 10,000 kilometers.

And it's not for nothing!

It is rumored that during the World War II, when Japan attacked Pearl Harbor, the president of the United States suddenly had to spend a day receiving two explorers returning from Mexico, and instructed his assistants not to arrange any outside interference.

So, who and what is it that deserves so much attention from the President of the United States?

It turned out that they were Mr. and Mrs. David Ram, who had been sent to Chiapas, Mexico, to conduct archaeological research.

After half a year of searching, the Rams came back this time and brought an amazing news to the president-

They finally discovered the legendary underground tunnels of Mexico, located in the dense forests of Chiapas, but due to the presence of Indians guarding the tunnels, they could not enter and had to come back to report.

At the same time, Hitler's spies in South America are doing whatever it takes to find underground tunnels, as well as the secrets of gold and ancient civilizations that may be hidden within.

Since war is a money-burning game, this astonishing discovery caused a great sensation at the time, and countries began to fight secretly around this underground world.

And before that, there was also information about this underground world.

In the mid-17th century, a Spanish missionary discovered an underground tunnel in Guatemala, Central America, which was located beneath a residential area in Puchota and appeared to be connected to the underground tunnels in Cusco, South America.

Later, a Jew named Stephens discovered an underground tunnel from western Guatemala to Mexico.

Later, in Cusco, Peru, an underground tunnel was discovered, which leads directly to Lima to the north and Bolivia to the south.

On the map, it is located beneath the Andes Mountains and is more than 1,000 kilometers long.

The Peruvian government, which learned of this news, in order to better protect this ancient civilization site, considering that with the current level of science and technology, it has not yet been able to develop and protect it, so it has re-closed the entrances of these discovered tunnels.

In modern times, it has been listed as one of the UNESCO World Heritage Sites.

In addition, deep underground on the South American continent, there is a larger, thousands of kilometers of vast tunnel system, but this tunnel is a personal possession.

The owner of the tunnel, named Juan Moritz, is an Argentine archaeologist.

He stumbled upon the tunnel in Ecuador in June 1965 and disappeared from public view.

After three years of silence, he revealed himself to the world, after surveying hundreds of kilometers of tunnels and discovering many artifacts.

In 1969, Moritz asked to meet with the President of Ecuador and reported to him about the tunnel, and in July of the same year, Juan Moritz received a certificate authorized and notarized by the Ecuadorian state.

Proof that he has ownership of the Ecuadorian underworld, but is subject to the control of the Ecuadorian national government.

Located at a depth of 240 meters, the tunnel is an extremely large and complex tunnel system, estimated to be more than 4,000 kilometers long, and it is not yet known where it eventually leads, and has only been examined and measured in a few hundred kilometers in Ecuador and Peru.

Now, the entrance to this tunnel, hired by Juan, is an uncivilized Indian department, which is closely guarded at sunset and night, and no one is allowed to enter.

Hu Xiaodao guessed that these caves must be connected to each other and through the entire Americas, but now they have the ability to enter it, and they will not disclose the information, and the specific situation inside is unknown to outsiders.

However, Hu Xiaodao's entry this time was not to prove whether these underground caves in various parts of the Americas were connected or not, but to rush to the prehistoric treasures inside.

Since these caves have been sealed by the government, Hu Xiaodao has to act alone, and as for how to transport the treasure out after finding it, he is also fully prepared.

After traveling for more than 2 hours, the plane finally came to the edge of the Chiapas rainforest, but it was still nearly 100 kilometers away from the coordinates planned by Hu Xiaodao.

The Chiapas rainforest is very large, covering tens of thousands of square kilometers, and it is inhabited by uncivilized and xenophobic Indian tribes, which are not much worse than the Amazons in terms of danger.

The plane moved forward for more than half an hour, and when it arrived at the top of the destination, Hu Xiaodao moved the mountaineering bag to his chest, carried the parachute bag to his back, patted the cabin door, and gave the pilot a thumbs up, indicating that he was ready to parachute.

"Good luck, my friend!"

The driver gave a thumbs up, raised his throat and said a word of blessing, and pressed the button to open the hatch.

The plane flies at an altitude of 2,000 meters, so it is not difficult to skydive, but if you want to find an empty landing point in the dense jungle, it is a bit difficult.

And choosing the landing site on the surface of a river or lake will only make the result worse!

The best result is to find a thirsty riverbed as a landing site for skydiving, and Hu Xiaodao chose this coordinate because directly below, there is a fierce rainy season, and other times there is a river less than 3 meters wide.

Although it was a little difficult to land on the thirsty riverbed, when the hatch opened, Hu Xiaodao did not hesitate and jumped out of the cabin.

After descending to 1,000 meters, Hu Xiaodao pulled out the parachute, controlled the direction, and floated all the way to the riverbed.

800 meters!

400 meters!

The elevation is constantly decreasing, and the location is good, and if nothing else, it definitely lands right on the sandy riverbed.

However, it backfired, when the altitude came to 200 meters, a strong wind came out of nowhere, and instantly took Hu Xiaodao crookedly and went straight to the dense forest.

A minute later, with the sound of branches breaking and the rustling of leaves, it was no surprise that Hu Xiaodao successfully hung on the tree.

For his unlucky luck, Hu Xiaodao is also very helpless.

Fortunately, it is less than 5 meters from the ground, and with a little attention, it can be safe, and it is not a big problem.
