Lena soon understood that he was in the lake of the heart.

Because the surrounding scenes only change color like film whitening, and there is no theoretical scale effect. The reason is that it is difficult for Lena to imagine what he will see when he reaches the speed of light.

Lena sat in his "office". Suddenly, everything around him poured into Lena's chest like a tide.

Lena is like a whirlpool, absorbing the whole world.

In retrospect, he was over his own heart lake.

Feeling the irrepressible agitation in his chest, Lena knew that now was the time.

Ripples gradually spread out in the sparkling lake, and the whole lake began to flood, submerging the surrounding land and spreading towards the boundless distance.

In just a few seconds, the originally quiet heart lake has become a rough sea!

The feedback from the world is so huge.

Lena knows that this is just the tip of the iceberg of the essence of light, but the feedback it brings has exceeded the sum of so many previous theories.

He had a feeling that he was about to explode. It was the process of wild primitive magic colliding, blending and digesting with Lena's own power.

With Lena's existing reserves, he can't digest such a huge magic!

He needs to create new spells!

For a moment, Lena felt something and looked up at the sky.

In the dark and cloudy clouds, lightning flashed by, and the low roar was like the roar of a dragon, shocking.

The shining stars are covered by dark clouds, and the whole world is dark.

Crackle -

a flash of lightning fell from the cloud and pointed to Lena's position.

It's thunder, it's energy, it's destruction, it's rebirth.

Lena raised his hand, the lightning immediately deflected, hit the sea, the thunder in the sea twists and turns, toward the spread of all around.

At the same time, in Reiner's field of vision, the extremely high energy contained in the lightning is transmitted to the sea. This energy causes the molecules to be scattered, the elements to re aggregate, and some hope is born from the ocean.

A sphere of light emerges around Lena, which shows that the computational array is running at a high speed.

Lenner has obtained two formulas, which are the scale effect and time expansion effect of length and time in high-speed motion.

But he has a third formula.

At this time, Lena saw a spot of light across the sky.

The speed of this light spot is getting faster and faster, gradually approaching the speed of light.

But Lena can sense that the speed of this light spot is becoming more and more difficult to improve.

In order to make the speed of the light spot faster, Lena provides more and more energy to it, but the speed of the light spot is always difficult to increase.

"Where does this energy go?"

Lena asked a question.

The kinetic energy of the light spot is obviously provided by the magic of Lena. The greater the energy, the faster the speed. But at this time, the light spot is fixed at the speed of light. Even if how to increase the energy, it can not increase the speed. So where is the energy provided to the light spot?

There's a formula coming up around Lena.

E=mv^2。

This is a simple kinetic energy formula, which means that the kinetic energy of a light point should be equal to the product of its mass and the square of its velocity. This formula is derived from Mr. Alberton's motion theory and has been verified in various fields.

But in the present situation, the energy of the object increases, but the speed does not change, and the energy will not disappear out of thin air, so it seems that there is only one answer.

That's the increase in quality!

But why does the quality increase!!?

In the cognition of mages, mass is the basic attribute of an object. As long as the object has no special change, the mass will not change. But now, the energy carried by the high-speed moving object increases and the speed remains unchanged. It seems that only the increase of mass can explain this phenomenon.

"Energy, transform into quality!"

Lena thought for a moment and said.

Buzz -

for a moment, Lena can feel the extremely high mass contained in the light spot, and its mass increases synchronously with the increase of energy.

In Lena's mind, countless pictures flashed.

It was the first time that I used magic. My fingertips lit a fire. It was a fire transformed from magic. Its essence was the combustion of hydrogen and oxygen.

He thought of the problem of magic efficiency that he had been thinking hard but could not get the answer. Even after learning the memory from the last era, it was difficult for Lena to explain this problem, that is, why the utilization rate of magic for magic was so low, and where was the loss of such huge magic to the bottom.

Now he has an explanation.

When magic is transformed from pure energy to the material needed for casting magic, the huge energy can only be transformed into a little mass. This is not the inefficiency of magic, but the law itself!The calculation matrix around him is suddenly bright, and a formula composed of countless rays appears in front of him.

This is the formula of everything he just experienced after calculation.

This formula explains how energy is converted into mass.

E=mc^2。

When an object moves near the speed of light, the energy obtained will be transformed into its own mass. The value of the transformed mass is energy divided by the square of the speed of light!

This formula reflects a point of view, that is, mass and energy can transform each other, mass is a form of energy, mass and energy are not absolute, they are not independent of each other, but closely related.

When a body is still at rest, it still has energy, while when it is moving, its energy is equal to the sum of its static energy and kinetic energy.

Matter is the aggregate of energy!

It was like a flash of lightning in his heart. In the whole sky, Lena saw that tens of thousands of lightning fell into the sea, forming a chilling and spectacular scene. The roaring thunder and the angry waves of the sea formed a symphony, which seemed to be celebrating the birth of this formula.

Lena raised his hand, and the light gathered to form an extremely complex constellation.

With little time to think, Lena completed the construction of this spell.

Everything seems to be natural.

He can feel that although he has deduced the equation of mass and energy conversion, because it is only a paper calculation, the feedback is not strong. Therefore, Lena did not choose to build magic based on the equation of mass and energy, but created an eight Ring Magic based on time expansion and scale contraction.

Complex constellations into Lena's chest, his heart felt, in the sky, the decaying thunder fell again, in the sea, devouring all the waves raised.

Lena step forward, from his side, a ripple spread away, immediately spread to the whole world.

The world is suddenly frozen.
