Therefore, it is impossible for Yun Lei to use the thunder and lightning spiritual power in the wooden ghost face to smash the heaven and earth spiritual fire that has accumulated energy for five or six hundred million years! What he wants to do is to attract another kind of energy in this earth's crust that has existed since the ancient times! The thunder and lightning energy is as vast as the wooden ghost face of the sea, and in the face of this energy, it is just a drop in the ocean!

In other words, the thunder and lightning spiritual power in the wooden ghost face is just the key to attract this energy.

In the movement of his mind, the cloud and thunder urged the thunder and lightning spiritual power that he could mobilize in the wooden ghost face to the extreme, and turned it into a line, slowly pulling out the vast and majestic energy in the center of the earth.

It is well known that there is a natural magnetic nature in the interior of the earth. And this natural magnetism forms an earth's magnetic field on the earth. This geomagnetic field extends tens of thousands of kilometers into space. Thus the Earth's magnetosphere was formed. The Earth's magnetosphere gives the Earth a barrier against the charged particles carried by the solar wind.

If there is no geomagnetic field, the powerful stream of charged particles emitted from the sun, that is, those high-energy particles, will directly bombard the earth, so that the living beings on the earth will not be able to exist at all.

And the reason why things like the compass on the earth work is because of the existence of the geomagnetic field.

Shen Kuo in the Song Dynasty of China recorded this in "Mengxi Writings" - "The Fang family sharpens the needle with a magnet, and it can be guided, but it is often slightly easterly, not all south." ”

It is precisely because of the existence of the geomagnetic field that the English scientist Gilbert thinks that the earth itself is a huge magnet!

Of course, the earth is not a magnet. Many things on Earth are not magnetic. So, this theory is not correct.

However, since human beings discovered the magnetism of the earth, and many things on the surface of the earth are actually not magnetic, the question of why the earth is magnetic has become an unsolved mystery. It has been discussed by mankind for hundreds of years. It was not until the human scientist Maxwell that he determined his electromagnetic theory - electric magnetism, magnetoelectric electricity.

It is only through the rotation and revolution of the earth that human beings have gradually understood the principle of the generation of the earth's magnetic field.

However, because human beings only know the deepest part of the earth, they only go deep below the surface, 10,000 meters, that is, 10 kilometers. So, not much is known about what the Earth's interior is like.

Only conjectures and inferences can be made from the data detected by the instrument.

Therefore, although human beings have generally understood the principle of the generation of the earth's magnetic field, no one can give a specific explanation for the process of the generation of the earth's magnetic field. All physical equations are flawed.

Scientists can only roughly explain this process as follows that there is a layer of liquid material in the core of the Earth's interior, that is, magma.

Because the main component of this magma is iron, but also a small amount of nickel and other metallic elements, even the ferromagnetism will completely disappear at the Curie temperature, which is 770 degrees Celsius. There are also many other metallic elements that can still conduct electricity in the molten state.

Even some substances that do not conduct electricity in the first place may conduct electricity due to high temperature and the activity of electrons outside the nucleus of the nucleus. For example, various inorganic salts in a molten state. In other words, magma is actually electrically conductive.

This layer of conductive liquid magma is called a conductive fluid because it is both fluid and conductive. In the rotation and revolution of the earth, the conductive fluid moves relatively. Then, inside the Earth's core, a relatively weak electric current and magnetic field are generated. Therefore, the interior of the earth carries a positive charge, and the closer to the center there is, the greater the charge.

This relatively weak magnetic field then excites the current in the conductive fluid and goes through a very complex mechanism similar to that of a self-excited motor to form a vast geoelectric and geomagnetic field.

And in the movement, a certain degree of coordination and stability is achieved.

And no matter what the specific details of the process of the earth's magnetic field generation, there must be an electric current in the depths of the earth, and it is extremely vast and majestic, and there are currents all over the depths of the earth!

In this way, only then can we achieve electromagnetism and derive such a strong geomagnetic field.

Geoelectricity has also become an important branch of basic geophysics. However, because of the strong current in the earth, scientists can neither observe nor measure, so the research has always stayed at a relatively initial stage.

The vast majority of data and phenomena are observed and measured by observing and measuring the Earth's magnetic field.

According to geologists, the morphology of the earth's magnetic field is inferred from the study of the shape of the earth's magnetic field. This terrestrial current is supposed to be a very thin layer of the earth flowing in the crust along the latitude.

This terrestrial current, which is most powerful near the equator, becomes much smaller at the poles of the earth. Because of the changes in the earth's crust, this terrestrial galvanic layer is not fixed. Rather, it is ups and downs, and it changes over and over again.

Where the current passes, it also leaves a corresponding trace. Rocks that are cooled above the terrestrial gallayer are remanent in a positive direction, and the magnetic inclination is downward. The rock that cools below the terrestrial current layer is remanent in the opposite direction, and the magnetic inclination is upward. Only in the place where the terrestrial gallayer passes, the rocks formed will not have residual magnetism.

The root cause of earthquakes is the rotation and rise of underground magma. Before the earthquake, the underground magma swirl will transport the magma close to the earth's core to the upper mantle, and in the process, the disturbance of the terrestrial galsphere will cause the deformation of the terrestrial galsphere itself. As a result, between the heavens and the earth, there will be a variety of colors and all kinds of strange shapes of the earth.

Let the world marvel at the great power of the heaven and earth at the same time, dizzy.

Ever since Yun Lei had a wooden ghost face and became the master of thunder and lightning, he had never thought of using this earthly current.

Because, for him, as long as he is above the nine heavens, there are endless thunderbolts to borrow. If Yun Lei was outside this heaven and earth, he would not have to exert such effort to attract the earth current.

As long as you can trap the spiritual fire of this heaven and earth, you can use the wooden ghost face to summon endless thunder from the atmosphere of the outside world. The amount of discharge is more amazing than the other. Even if this heaven and earth spiritual fire has accumulated for hundreds of millions of years, it will definitely not be able to hold it.

However, Yun Lei was in this underground space, and he couldn't borrow the Nine Heavens Thunder and Lightning at all. This underground space, the difference between the dome and the underground, although thousands of meters, has formed its own water circulation system. There are also water vapor and clouds.
