From the perspective of the development of the entire periodic table,

This seemingly useless integration has laid an important foundation for the progress of modern human science and technology.

And Xiaoguang also flickered for a while after listening to the invention process of the periodic table, and was speechless for a long time.

Seeing that Xiaoguang was silent and didn't ask him about dreams, Yang Meng suddenly thought of a possibility:

"Do you have dreams too?"

"Dreamland...... In order to save energy, we were able to do away with this useless function very early on......"

Saying this, the light flickered, and he fell into a certain emotion again.

"So he has dreams!"

……

The spaceship continued towards Ice Debos,

On the fifth day of leaving Ice Deimos,

The Boundless Orient that Yang Meng was riding finally approached Ice Medios.

During this period, Yang Meng and Xiaoguang exchanged some questions,

And there is also more detection data from another layer of the star.

The data on that fluorite became more detailed, just like the ice giant star system he was in at this time.

That planet also has a more complex system of moons.

Originally, Yang Meng planned to leave the Rutan planet and go to the E planet.

But now, he's going to take a look at the satellite that Xiaoguang is pointing to.

In this way, Yang Meng operated the spacecraft and flew for nearly a day.

After a series of actions such as constantly changing orbits and adjusting speed, he finally entered the gravitational perturbation orbit of Ice Debos.

Because the volumetric mass of Ice Medios is too small,

Yang Meng's Boundless Oriental,

It is very difficult to enter the orbit of Ice Deboletto.

Therefore, it is necessary to activate the auxiliary power system on the spacecraft to orbit Icebos.

Thanks to the nuclear fusion reactor on his spacecraft, the human ionic propulsion device is also very mature.

If it were a spacecraft from his grandfather's time, although it could also orbit small celestial bodies,

However, it can only be run for a short time, and cannot be orbited for a long time.

After entering the orbit, Yang Meng began to probe Ice Guardian.

The maximum entity radius of Ice Medios estimated by the centroid is only 312 kilometers.

Previously, when the small other side instrument swept over the Ice Deimos, it only detected a thickness of 60 kilometers.

And most of the composition of this part of the matter is the very common water ice matter in the universe, and some small amounts of light elements after solidification.

In this part, the heavy elements are very rare,

As for the deeper substances, the detection capabilities of small detectors have not been able to penetrate deeply.

Although it is impossible to go deeper,

However, according to the detonation detection of small celestial bodies, most of the materials in the core under the ice are silicon, nickel, and iron.

And these elements are not the rare heavy elements that Yang Meng urgently needs at the moment.

"So, the detected radioactive elements are inside Ice Debas?"

Yang Meng operated the neutrino detection device while confirming something to Xiaoguang:

"I can't confirm the exact depth of the radioactive elements.

But the string movement here is the strongest outside of the blue planet! ”

Hearing such an answer,

Yang Meng nodded slightly, stretched out his hand to activate the detection device, and began to search for Ice Guardian.

……

Under the reflection of a huge planet that is cold and blue,

A ruined spaceship, orbiting a potato-shaped planet,

The next moment, three points of light broke away from the spaceship,

Moving at different angles towards the beginning of the circle around the potato-like planet,

When the three points of light are on the same spherical plane as the spacecraft, and the circle formed by the three points of light and the cone area formed by the spacecraft happen to contain the potato planet.

Neutrino searchlight signals that have long been charged,

Launched from the spacecraft, it passes through the potato planet with the extremely penetrating ability of neutrinos, and lands in the area formed by three miniature detectors behind

So a piece of probe data was sent back to the spacecraft.

However, this data alone cannot determine the condition of Ice Medisos.

Over the next few hours,

The neutrino detection device emitted by the spacecraft, constantly changing its position, emitted detection particles towards Ice Medisa.

With the assistance of computer systems,

The internal structure of Ice Medios has also been improved little by little.

Looking at the gradually improved internal diagram, Yang Meng's expression gradually changed:

"It's ......"

Ice melados is structurally a very normal small celestial body.

There is a cooled rock core inside, and the outside is covered by a thick layer of ice.

However, unlike other celestial bodies,

At 171 kilometers below the ice, where the rock core is divided into ice, there is a very regular rectangular area.

And the radioactive elements on Ice Medisos also come from this area.

"What is this?"

Looking at this very orderly area, many thoughts flashed in Yang Meng's heart,

"It doesn't look like a natural creation!"

Although there are naturally occurring standard cubes on Earth,

For example, pyrite, regardless of its luster or the standard degree of the cube, is like a modern industrial product.

But that kind of Rubik's Cube structure is indeed a product of nature's coincidence structure.

Therefore, in the face of the current situation,

Yang Meng's first thought was that the cuboid structure under the ice was not a natural product of special celestial movements.

can be Xiao Yi, after the material analysis of the cuboid area is completed,

Yang Meng completely dispelled the idea that this was a natural product:

"According to the comparison of τneutrino spin perturbations, it can be determined that the radiation source in the radiation region is mainly radium!"

"In addition to radium, rare heavy metals thulium, rhodium, molybdenum and ...... were also found"

……

"Radium!"

"Wait!" Hearing the element of radium, Yang Meng hurriedly interrupted Xiao Yi's data and confirmed something to her.

"I don't think radium has a long half-life?"

"Yes, compared to other radioactive elements, radium has a maximum half-life of only 1,600 years!

During this period, radium will slowly turn into radon and helium......"

"1600!" For Xiao Yi's later explanation, Yang Meng didn't have the heart to listen.

Such a short half-life has already set off a storm in his heart,

Fortunately, with the quality of an astronaut, he quickly calmed himself down.

"I remember that the element radium was discovered by Marie Curie,

The half-life of radium is so short, with the age of 4.5 billion years of the earth, there should be no such element as radium on the earth.

Since radium can be discovered by humans,

So it is very likely that this element is decayed from other elements? ”

"Xiao Yi! What substance is radium produced from fission? ”

"It's a uranium fission product!"

"So in that cuboid area, did any uranium element be detected?"

"According to the current searchlight data, no uranium has been found!"

"Depleted uranium-238 is not either!"

"Yes!"

Hearing this answer, Yang Meng also fell into a momentary distraction.
