The sun is shining.

Chen Zheng was half-lying in the rocking chair and swaying gently, the sun shining into the room through the window, and the sun was warm on his body.

On his lap, there was a model of the railgun that had changed dramatically, the wooden model representing the capacitance was gone, and the messy copper wires were gone, leaving only two copper rails and the crossbow machine behind the copper rails.

After continuous simplification and removal of all anachronistic designs, the final result is a weapon that resembles a crossbow more than a cannon.

"Hmm......"

Chen Zheng moved, muttered a few words indistinctly, and fell asleep again.

In a daze, Chen Zheng felt as if he was floating in mid-air, as if gravity had lost its effect, making him float around in the wooden house like a fish in the water.

He swam and swam and swam and swam and suddenly accidentally hit the wall, and then the whole person passed through! The whole person just flew and flew and flew until it reached the sky......

I don't know how long it took, but suddenly ......

"Boom!!"

Huge lightning fell from the sky and draped over a tall tree.

Chen Zheng woke up with a spirit.

I don't know when, it was already dark. Outside the window, it was gloomy, and heavy dark clouds hung over the land. Chen Zheng suddenly frowned.

Reality is the same as dreams?

Just now in that ethereal dream, Chen Zheng seemed to be swimming in the nine heavens, witnessing the scene of the gathering of wind and clouds, a large number of clouds were carried by the wind and gathered here, piled up into this thick dark cloud.

The convergence of cold and warm air currents made the wind and clouds constantly stir and rub, and until this time, Chen Zheng still clearly remembered that the water molecules floating in mid-air were frozen into graupel particles in the wind, and collided and rubbed against the ice crystals in the clouds......

…… The temperature of graupel and ice crystals is different, and the content of free ions is naturally different, and high-temperature graupel particles contain more free ions, and ions will inevitably migrate from the high temperature end to the low temperature end. When the wind blows away the graupel particles and ice crystals, the warmer graupel particles have more residual hydroxide and carry negative electricity, while the ice crystals accumulate more positively charged hydrogen ions.

The lighter hydrogen ions are swept by the wind and fly higher into the clouds, while the negatively charged hydroxide ions sink under the force of gravity.

Air is a bad conductor, and the different molecules that pass by and lose their charge are separated by air...... The electric potential difference is generated, and an incomparably large amount of energy continues to accumulate between the clouds.

The positive hydrogen ions are constantly gathered together, and the strong demand for electrons creates a huge attraction, like a beast in estrus, trying in every possible way to get electrons to complement itself.

With the continuous accumulation of positive charges, its attraction becomes greater and larger, and gradually turns into a powerful energy, which exerts a huge attraction on all electron-carrying substances......

The friction continues.

Stirred by the wind, hydrogen ions continued to accumulate, and gradually their attraction far exceeded the resistance of the air, and everything happened in an instant.

With a violent flash, a loud bang slammed through the air.

In the midst of the rolling thunder, five or six rays of lightning pierced the air, and the yin and yang charges were connected together like a number of firewood.

But that's still not the end.

The gas molecules, which have been forcibly stripped of electrons, take on a positive charge and once again spread the attraction in all directions. The resistivity of the air that had just been broken down still did not recover, and naturally such a violent discharge began again.

With bursts of light, the molecules in the air continued to lose their charge, and then regained their charge, and finally after a large number of electrons were fiercely deprived from the earth, everything finally quieted down.

At this time, Chen Zheng also opened his eyes and saw the last scene: a huge lightning bolt was conducted upward along the ionized air, producing a bright and dazzling flash of light, and finally disappeared into the clouds.

"Just ...... What's that......"

Chen Zheng stood in front of the window in a daze, letting the wind tear his hair and slap his cheeks.

This is how lightning is formed!?

The thunder and lightning observed on a daily basis are not the whole story, they are actually composed of several violent electrical discharges in a very short period of time, and finally turn into a thunderclap and a lightning bolt.

But that's not the point, the point is what was that out-of-body state just now!?

The blizzard did not fall.

The wind gradually subsided.

It seemed that everything just now was just a dream, but the snowflakes that were swept in by the wind in front of the window told Chen Zheng that everything just now was not a dream.

Or rather, it's not just a dream.

Everything just now seemed to be as clear as a movie in Chen Zheng's mind.

When graupel particles at different temperatures collide with ice crystals, the separation of hydroxide and hydrogen ions, and the huge drought thunder produced in the end, Chen Zheng has a deeper understanding of electricity.

Hydrogen ions and hydroxides, one with a positive charge and the other with a negative charge, the hydrogen that loses its electrons becomes a positively charged ion, and as the positively charged hydrogen ions continue to gather, it eventually forcibly deprives the surrounding air molecules of their electrons.

And those air molecules that have been deprived of electrons go down layer by layer to deprive other air molecules of electrons, and finally turn into the lightning that connects heaven and earth.

So the nature of electricity...... Seems like an attraction?

What is the attraction of cations to anions?

Or the attraction of the nucleus to the electron?

So......

What if I just made a nucleus with no electrons and a huge positive charge?

This thought suddenly appeared in Chen Zheng's mind and was out of control. Impatiently, he took out a small wooden box and opened it carefully, dipped a little white powder in the wooden box with a toothpick, and then carefully put the wooden box aside.

These white powders, which were the strange fish crystals that Chen Zheng had ground before, originally wanted to "refine" superconducting materials with copper powder, but now they just came in handy.

In chemistry, only the outermost electrons of the nucleus are shared between atoms. For example, lithium in batteries only appears in the form of +1 valence lithium-ion.

However, in physics, lithium has a number of electrons outside the nucleus of 3, so theoretically there should be a +3 valence lithium ion.

It's just that until Chen Zheng came to this planet, it seems that he has not heard of the existence of +3 valent lithium-ions, and he has not even heard of related research.

But the ultra-high valence ions do exist.

For example, iron in the sun exists in the form of an atomic nucleus that loses all electrons outside the nucleus – this has been confirmed in astronomical observations.

So, what happens when ultra-high valence ions are exposed to air?

Holding the toothpick stained with strange fish crystals, Chen Zheng took a deep breath, and then a trace of blue light flashed in his hand......

"Click!"

A dazzling arc of lightning pierced the air and connected with the metal on Chen Zheng's desktop!
