At this time, the phone vibrated a little.

APP pops up a message.

"Please rest assured that this artifact is completely harmless to the host. Please explore the specific value and function of the treasure on your own. ”

After reading the message.

Han Zhou was also relieved.

Pick up this "little pyramid".

The small pyramid is about the size of two steamed buns, and it is very lightweight, much lighter than ordinary metal.

It's a little lighter than the aluminum alloy used in the windows.

Han Zhou weighed it twice. So I took it down the hill and returned to the car.

Drive.

Return to the hotel.

Look up the pictures on the web.

I used Baidu's picture recognition function, and I checked it for a long time, but I didn't find it.

I went to the headlines again and searched for terms with various keywords.

I searched for more than ten minutes.

I found a piece of interesting news.

On November 18, staff of the Utah Public Safety Department of the United States discovered a mysterious metal object in the desert in the southeast. The metal object is about 3 meters high, pillar-shaped, and has a very flat surface (so large and so regular, it is almost impossible for it to be naturally formed), standing in the red rock. The whole picture looks like a scene from the movie "2001: A Space Odyssey".

Barrett, a helicopter pilot, told local news channel KSLTV, "This is the strangest thing I've ever encountered in my years of flying." ”

Some netizens speculated that this was a work of art, and some netizens opened their minds and said that it was left by aliens.

In this regard, the official of the United States humorously said, "No matter what planet you come from, it is illegal to install buildings or works of art on public land without authorization."

Later the column was moved.

Next up is the series.

On November 26, a metal column similar to the recently discovered in Utah appeared on a hillside in the city of Piatra Nimut in Nimut County, northeastern Romania.

This metal pillar stands opposite the Chahelao Mountain, which is regarded as a "sacred mountain" by the locals, and the surface of the column is engraved with a mysterious ring symbol.

Romanian cultural heritage officer Rosana Chosanu said: "We have started investigating this strange metal column. It may be private property, but it is still not known who is the owner of this metal column. It is located in the protected area of an archaeological site. Before installing something there, you need permission from our agency, and you also have to get approval from the cultural department. ”

A few more days passed, December 2nd.

A third mysterious metal pillar has reappeared on a mountain in California, USA. Witnesses said that when he went up the mountain for a run the day before, there was no such object. On November 28, the metal monument in Utah was removed. On December 2, the metal object in Romania also "mysteriously" disappeared.

From a pragmatic point of view, this metal pillar may be a work of art by some performance artists.

But being so popular shows that it caters to the long-standing curiosity of netizens around the world about "alien ruins".

In the early years, the series of books that were popular in the continent: "XX Unsolved Mysteries", introduced many similar things.

One of the most famous is the "crop circle".

A crop circle is a geometric pattern created by flattening crops by some unknown force in a wheat field or other field. (Of course, many crop circles are actually imitated after the "crop circles" became popular.) ）

The "smooth collapse" of crops and the scorching marks of plant stem joints in the cycle do not seem to be able to be done by human flattening, and some MIT students have tried to reverse replicate this phenomenon with homemade equipment but have not been able to do so, and it is still unexplained what kind of equipment or method can achieve this phenomenon. (xx unsolved mysteries like to render this kind of content, and make it very mysterious, so as to increase sales, but this is not necessarily the case.) ）

The advent of crop circles has given people who support alien existentialism a variety of opinions.

At one time, it became the most famous "evidence of the existence of aliens" in the last century.

And with the blessing of the infinite imagination of aliens (and possibly earthlings), they have developed all kinds of strange crop circles.

Except for the most common wheat and barley circles. There are also the following.

Grass circles. As the name suggests, it appears in the grass. It generally appears in March ~ May, and is often the first circle to appear every year. It is mostly found in the Netherlands. Aliens also know how to adapt to local conditions and teach students according to their aptitude.

Rape rings. Rape fields appeared. It mostly appears in April ~ June. The annual crop circle in Wiltshire, England, often starts with a rape circle.

Cornfolds. Appears after the wheat is harvested. Corn is often uprooted. Aliens who do cornfolds do not care about the environment.

Cryosphere. In winter, when most of the crops are harvested, snow circles sometimes appear. The surface of the snow circle is smooth, and there are no footprints nearby, which is similar to the scene in a Japanese Benge-style mystery novel. Circular ice circles have been found on the ice in the Arctic, Canada, the United Kingdom, Russia, and other places.

Elven circles. A unique phenomenon in the western coastal area of the Namibian desert in South Africa, the diameter of the circle varies from 2 to 10 meters, and the circle is full of sand and no grass, but there are lush wild grasses around the circle.

There are also desert circles, modified circles (after the first day appears, the pattern will be corrected after the second day, generally man-made circles, such as the wheat circle is halfway built and the wheat is not enough, so the project is postponed), ghost circles (after the wheat circle is destroyed, the next day the crop regrows, and there will be pattern traces due to the influence of the wheat circle in previous years), woven wheat rings, signed wheat circles, and so on.

The creativity of the aliens is very strong.

Earthlings are also very curious about aliens, regardless of country.

Han Zhou held a small pyramid in his hand and played carefully. Since the APP said that it was completely harmless, he didn't have to worry about things like if he pressed a button, the alien spacecraft received the signal and took him away.

Take a closer look at the details of the small pyramid.

The small pyramid is made of metal. The color is dark blue and almost black, the surface is very flat, I don't know if it's an illusion to the touch, I always feel as if the surface is covered with a thin layer of oil, very slippery.

But rubbing my fingers and putting them under my nose to smell the smell, I didn't find any traces of oil.

It's amazing.

Han Zhou thought to himself.

It can't really be an item left behind by aliens.

Or prehistoric civilizations.

No matter what it was, since it was a golden light point level treasure, it would definitely be priceless, but he hadn't discovered it yet.

Han Zhou also observed the circle pattern on the surface of the small pyramid.

At first he felt a little scary and his scalp tingled.

After watching it for a while, I got used to it.

It's nothing more than a circle.

The largest one is half the size of a fist, and the smallest one is less than a micron in diameter, which is extremely small and extremely small.

There may be smaller ones that require a microscope to see.

The circles all shimmer with a faint blue metallic glow, shimmering in the light.

Unconsciously, Han Zhou indulged in it.

I don't know how long it took, Han Zhou suddenly woke up.

Take a look at the watch time.

Two hours passed.
