Although Lu Fan didn't know why the vibration could promote the fusion of energy, it would even greatly increase the power of energy.

But he knew that when the frequency of the vibration is the same, there will be an inexplicable connection between the two vibrating objects, and then the purpose of fusion will be achieved, and even, because of this connection, the two vibrating objects can strengthen each other.

This is what Lu Fan has seen and felt with his own eyes, he has been experimenting these days, and he has made a lot of discoveries, but the direction of his previous research is more to integrate it into the runes, rely on the runes to achieve vibration, and then fuse.

But now he realized that he was wrong, the principle of vibration was originally a rule of energy, and it could be used not only for runes, but also for the use of energy.

Like seeing the sun through the clouds and being empowered, Lu Fan had a feeling of sudden enlightenment at this moment.

However, Lu Fan soon encountered a new problem, how should he control these energy rays to vibrate?

If it vibrates up, down, left and right, it will inevitably interfere with the vibration of other energy rays, and after this vibration, it will no longer be able to rotate.

Bai Zhi looked at Lu Fan, who was floating in front of him, and this energy ray was constantly making various movements, although she didn't know what Lu Fan was doing, she still didn't wake him up.

Although, without Lu Fan's help, the pressure on her to face the Earth Rock Bear alone doubled.

"What if you give up spinning and just shake?"

This thought popped up in Lu Fan's heart, after all, the shadowless, formless and silent fluctuations before were also only fused together by vibration, and it told Lu Fan that the power of vibration fusion alone was already amazing.

An energy ray appeared in his right hand again, and Lu Fan made the two energy rays move up and down in front of him synchronously, so that their frequencies remained the same.

However, although Lu Fan could feel that there was indeed a connection between the two energy rays, it was just that he was stumped again, how could he fuse the two energy rays?

Lu Fan patted his head vigorously, he knew that he was in a bottleneck at this time, if he couldn't break through, his combat strength would not be able to improve, and once he broke through, then the Earth Rock Bear in front of him would no longer be his opponent.

Because it is necessary to fuse, it is not possible to let the energy rays themselves move, which will hinder the fusion, so you can only let the energy rays vibrate inside.

Lu Fan took a deep breath and cleared his thoughts one by one in his mind.

"Control the vibration of every particle inside the energy ray?"

This idea immediately came to Lu Fan's mind.

However, in the next moment, Lu Fan denied his idea and controlled the vibration of energy particles, not to mention him, even if he was a palace-level master, I am afraid that he would not be able to do it, such an amazing control power is probably possible for a master to touch.

Don't look at an energy ray that is only the thickness of a thumb and a few centimeters long, but the number of energy particles in it is a terrifying order of magnitude.

With so many particles, not to mention controlling vibration, even if it is completely perceived, it is not something that Lu Fan can do now.

Of course, Lu Fan could also control some of the vibrations, after all, his perception was still very good in entry-level energy cultivation, but how many particles of vibration was appropriate to control?

How many particles need to be controlled to vibrate the energy rays?

How many particles can be controlled to vibrate in order to maintain the original properties of the energy rays?

Even if Lu Fan can do this, it will take countless attempts, and even, in the most likely case, he can't do it at all.

But in any case, it is not what Lu Fan can do now, how can he have so much time now.

"Self-shaking ......"

Lu Fan muttered unconsciously.

Suddenly, a spring vibrated in his mind.

"Spiral hollow structure, yes, that's it!"

His heart was ecstatic, as if he had discovered some treasure, and although he hadn't tested it yet, he had an inexplicable feeling that he would succeed this time.

The structure of the spiral hollow only makes the energy ray the shape of a spring, making it vibrate by itself, but it does not affect others, and even Lu Fan can continue to use it to rotate.

"No, you can also make the front end of this spring a sharp spiral, so that under the cooperation of rotation, it can also greatly increase the penetration of energy rays......"

Lu Fan felt as if a hole had opened in his head, and all kinds of thoughts couldn't wait to pour into his mind.

At this time, Bai Zhi's situation was also getting worse, her hand with a spear began to tremble, and the water body was also accidentally slapped by the earth rock bear and an arm was missed.

Fortunately, the water body is only energy condensation, as long as Bai Zhi has enough energy, she can keep recondensing her body, but after a long time of high-intensity fighting, Bai Zhi's consumption is becoming bigger and bigger, even if she is already a one-star professional-level cultivator, she can't last long.

This time, Lu Fan sent out three energy rays, he first changed the structure of the three energy rays to make them a hollow spiral spring-like structure, and then kept them at a suitable vibration frequency, and finally made the three energy rays rotate.

After doing all this, beads of sweat had begun to appear on Lu Fan's forehead, and his face became a little pale, not because of too much energy consumption, but because this action, the consumption of perception was too terrifying.

Lu Fan meditated in his heart, when this time was over, it was time to redesign the structure of the two fist gauntlets, and at this moment, Lu Fan suddenly understood that the rune technique was originally part of the energy rules.

And the use of rune technology is to allow people who do not perceive enough to use moves with more advanced energy rules.

For example, he made the energy rays emitted by the gloves directly into a spiral hollow shape, so that he could save an unknown amount of force.

As the rotation and vibration continued, Lu Fan could faintly feel the tremendous destructive power contained in the rotating cone-shaped energy cluster.

However, Lu Fan still seemed to be a little dissatisfied, and with a slight movement left and right, more than a dozen energy rays flew out of his left hand again, like a swimming fish, flexibly attached to the rotating cone, and then rotated with it.

Moo......

Knock knock knock......

The Earth Rock Bear let out an angry and happy roar, then hammered its fists hard in the chest, making a dull hammering sound.

After being entangled for so long, the water body was like a mosquito, jumping up and down, and it kept buzzing around his ear, which made it annoyed, and at this time, it finally slapped the hateful mosquito to death, and it only felt very happy in its heart.

The red eyes looked at Lu Fan and the four of them, and the killing intent in their hearts was already boiling.
