The black sphere sat safely in the transparent vacuum glove box, surrounded by four heavily armed men, who wanted to approach but did not dare to get too close, as if the contents of the box had a fatal attraction and were extremely dangerous, like a gem on the forehead of a poisonous snake that glowed coldly.

Jiang Zi, Lou Qi and Liang Jing had already changed their clothes, the bloated and tight protective clothing was like a transparent hemp bag on their bodies, and no one spoke in the laboratory for a long time, only the sound of heavy breathing one after another.

The four men were silent in shock, and in their long career of study and scientific research, there was probably no such moment when their long-ingrained worldview was shaken.

"It's ...... You dug out of Napoleon's pit? It's not playing with me, is it? ”

Hu Donghai touched a mask, his head was covered with sweat, and he subconsciously wanted to wipe his sweat.

"Play with you and me to die for the whole family."

Jiang Zi said.

"What the hell is this?" Hu Donghai asked.

"As you can see...... Liang Jing stood across from him, "it's a ball." ”

"You dug a ball?"

"yes, dig a ball."

In the center of the glove box is a silver tray, on the tray is a black smooth sphere, about ten centimeters in diameter, I don't know what material it is, not like metal, a bit like marble, the surface is very smooth, according to Jiang Zi and them, this thing is excavated from the hard ice and permafrost, but what is surprising is that there is not the slightest scratch on its surface.

The tray is actually a sophisticated electronic scale that calculates the standard mass of the black ball.

2.72 kg.

"Napoleon Pit...... Hu Donghai muttered for a long time, "the geological pit on the edge of the half-foot lake? ”

"Yes."

Half a foot lake is not far from Cassini station, about two kilometers away, and it only takes 30 minutes by car - due to the extremely low gravity and strong wind on Titan, ordinary tracked construction vehicles cannot be used here at all, and all the personnel carriers in Cassini station are low like crabs and move on foot.

That's right, move on foot.

Each car has six small short legs, the ground is low, climb up like a cockroach, take small steps, the speed is very slow, but can overcome complex terrain and bad weather, the storm comes heavy excavators can easily roll away, at this time the transport truck will shrink its head and lay its body flat, the bolts on the six legs penetrate deep into the ice under their feet, and hold themselves firmly in place.

Anyone who is more than 200 meters away from the station must take the bus.

Half a foot lake is the closest large lake to Cassini, the official name of this lake is Dongting Lake, but it is obviously 108,000 miles away from the Dongting Lake 1.2 billion kilometers away, I don't know which god came up with such a name with brain cramps. The total area of the half-foot lake is more than forty-six square kilometers, and there is no edge to see from the edge of the lake, but the depth of the lake can only be submerged to the calf of an adult.

Satellite telemetry shows that the lake is like a shallow saucer, a 46-square-kilometer saucer, the surface and bottom of the lake are extremely flat, the deepest part is 44 centimeters, the shallowest part is 42 centimeters, and the maximum drop is not more than 2 centimeters.

With more than 20 million cubic metres of liquid methane in the lake, it serves as a natural fuel reservoir.

Hu Donghai stared at the black sphere inside the box, the black ball was sealed in the transparent plexiglass glove box, and he was sealed inside the protective suit, the two sides were completely separated in space, at least three layers of transparent material.

As the scientific director of Cassini Station, Hu Donghai is an experienced astrophysicist, he is 55 years old this year, he set foot on Titan for the first time at the age of 45, when Cassini Station was not even established, and so far he has been on the Titan for a total of three years and six months, making him one of the longest people in the world who has stayed at Cassini Station.

After spending a long time on Cassini Station, the novelty has long passed, there are more disappointments than hopes, and Hu Donghai has become an old salted fish soaked in methane.

What is Titan?

Titan is just a cold, dark, dark and silent planet, except for **** is ****, it has little research value, and it is extremely boring.

Hu Donghai's throat moved, and he opened his mouth to say something.

Jiang Zi said that this is a big treasure, compared to it the Nobel Prize is not worth mentioning, now it seems that this is reasonable, this is really too amazing a discovery, it can completely change the history of mankind, if this news is transmitted back to the earth, it will definitely cause a sensation. Hu Donghai was still able to maintain his composure because he couldn't be sure of the authenticity of this thing for the time being, if it wasn't for someone who had buried this thing in the ground as a prank, then it could only come from the outside world, from a non-human hand, from a completely unknown place.

"Someone can't be in the pit, right? Could it be a part of some kind of construction machinery? Hu Donghai raised his head and looked away, "See if it is printed with MADE IN CHINA." ”

"There is no MADE IN CHINA." Liang Jing shook his head, "There is no license or mobile phone number, and there are no such parts on all the construction vehicles, it doesn't look like a man-made object from the earth." ”

"Naturally formed?" Hu Donghai then asked, his attitude was very cautious.

"It's not like it's natural." Liang Jing shook his head again, "I've been engaged in geology and minerals for so many years, and I've never seen anything like this." ”

Jiang Zi put his hands into the rubber gloves and touched the ball gently, it was smooth and hard to the touch, it was minus 170 degrees Celsius when it was dug out of the permafrost outside, and the current room temperature was 25 degrees Celsius, such a large ambient temperature difference did not cause any effect, the black ball was still hard and smooth.

This shows that the material of its composition is beyond everyone's imagination, and although it looks like polished and smooth marble, it is obviously impossible for the marble to withstand such drastic temperature changes.

"Lao Hu, do you think this is done by aliens?" Jiang Zi asked with a smile, "We have discovered alien ruins, we are going to go down in history, you big scientists hurry up and study this thing, the Nobel Prize will definitely be soft, remember to share a little bonus with me when the time comes...... Gou is rich and rich. ”

"Aliens did it? Eggs laid by aliens? Less. Hu Donghai pressed the button on the operation panel of the glove box to make the results of the electronic scale more accurate.

The numbers flashed.

The mass was accurate to milligrams, which became 2.718283 kilograms.

Hu Donghai was stunned.

The three people around glanced at it, and they were all taken aback.

"Coincidence?" Lou Qi asked aloud.

Hu Donghai waved his hand, signaling him not to make a sound, and then pressed the button again to be more precise.

Accurate to micrograms.

2.718281828 kg.

"Can you go any further?" Liang Jing said softly.

Again, exactly, tenths of a microgram.

2.7182818285 kg.

And then precisely, hundredths of a microgram.

2.71828182846 kg.

No matter how precise, one thousandth of a microgram!

2.718281828459 kg.
