It only took him less than a minute to successfully compress the main brain energy wave, and at the same time, at this moment, the sphere wall membrane was removed!

At the moment when the membrane of the sphere wall was withdrawn, the compressed energy wave began to become unstable again, but with the experience of the last time, Liu Yu immediately controlled the compressed energy wave, and at an extremely fast speed, approached the feathers on the table.

This time, while Liu Yu was concentrating on manipulating the compressed energy wave, his eyes were staring at the feathers on the table almost without blinking.

The moment the compressed energy wave approached the feather, it escaped again, and the aftermath of the escape spread out in all directions with an impact that I didn't know if it was real.

Under this impact, Liu Yu felt dizzy in his head again. But having learned the lesson of the last time, even in vertigo, his eyes were fixed on the feathers on the coffee table.

And at the moment when he felt dizzy, the feathers on the coffee table, as if blown by the wind, swayed and floated for a short distance and fell to the ground.

Suddenly, Liu Yu couldn't care about the dizziness in his head, and he was so happy that he almost jumped up!

"It worked, I made it!" Liu Yu was overjoyed, "It seems that the way to compress the energy wave is indeed the right way to turn the energy wave into reality!" ”

Once he touched a little bit of the doorway, Liu Yu's cultivation of the third layer of the soul cultivation method was also much more thorough.

Now, he can only compress two-fifths of the energy wave to one-fifth of the volume, and he can already whisk feathers. If one day, he can compress all the energy waves in his body into a very small volume, then the power of the main brain energy waves will not be the same as now.

When he thought of this, Liu Yu found that he seemed to have found a great avenue on the way to the cultivation of the main brain energy wave.

At the same time, he also knew that he couldn't rush for quick success, and at this time, he didn't try to compress more energy waves, but tried to maintain the two energy waves that had been successfully compressed in a relatively stable state.

Maintaining the compressed energy wave in a stable state was much more difficult than the first two layers of the pre-cultivation soul cultivation exercise.

It took Liu Yu more than a day, and he could only maintain twice the energy wave in the compressed state for one minute.

One minute seems to be his limit at this stage, after a minute, the compressed energy wave will automatically escape, and no matter how much he adjusts, he will not be able to sustain it for much longer.

However, while the compressed energy wave only lasts for a minute, it's terrifying enough.

Just imagine, if Liu Yu manipulated the compression energy wave and sent a soul attack to the opponent. One minute was enough time for him to invade the sea of consciousness of his opponent with a wave of compressed energy.

At that time, as long as Liu Yu let the compressed energy wave explode in the opponent's sea of consciousness, the aftermath of the explosion, the strong people below the S-level, would definitely be annihilated in an instant.

And the S-level powerhouse will have a qualitative leap in soul compared to the A-level, but even so, the S-level powerhouse, if attacked by Liu Yu's compressed energy wave, is estimated to fall into a coma for a period of time. At that time, even if it was only for a moment, it was enough for Liu Yu to end the life of that S-level powerhouse.

Moreover, this kind of soul-level attacks are all attacks between the virtual and the real, and with the technological level of the Kalan planet, in the face of this type of attack, there is no other way to defend except to use the strength of the soul itself to resist.

It can almost be said that after Liu Yu mastered the move of doubling the compression energy wave, he was already at the top of the S-level powerhouses in terms of combat power in single-handedness!

Liu Yu was able to double the compression of energy waves, all of which the head of the Xiahou family would never have imagined.

The head of the Xiahou family has been cultivating that set of soul exercises for more than fifty years. It took him more than fifty years, but he could only do it to the extent that he could compress his mental power to the same extent as Liu Yu.

And it is such an achievement that has made him stand at the peak of the S-level powerhouse, and he has not fallen in the military world for many years.

In the entire Xiahou family, apart from those old monsters who have not been born for a long time, there are only a few people who have reached this level in soul cultivation. Most of the other people who had cultivated the Soul Exercise had not even touched the threshold of the realm of compressing spiritual power.

It can be seen from this that the difficulty of cultivating this soul exercise is very high. In addition, the cultivation exercises given to Liu Yu by the head of the Xiahou family have already eliminated many key places, so the head of the Xiahou family would never have dreamed that Liu Yu would be able to cultivate the soul exercises to this level without relying on guidance!

This time, Liu Yu can be regarded as tasting the sweetness from the doubling compression of this energy wave, and in the next few days, he has been cultivating this soul technique.

But soon, he found that his cultivation efficiency had dropped a lot, and after a few days of cultivation, he hadn't gotten much results.

He had tried to increase the energy wave from twice the compression to the third compression, but unfortunately, after a few days, all his attempts ended in failure. He felt that he seemed to have reached some kind of bottleneck in the refining of the main brain energy wave, and if he did not break through this bottleneck, it would be difficult for his main brain energy wave to reach the level of triple compression.

As for the breakthrough of the bottleneck, it is not possible to break through it by diligent practice, which requires some kind of opportunity.

And at this moment, Liu Yu knew that it was time for him to end this state of closed-door cultivation.

In the following time, Liu Yu returned to his usual idle appearance, sometimes strolling around the courtyard of the Medicine Villa during the day, and sometimes sitting in the lounge of the small building store for half a day.

Occasionally, when he received an order for a customized potion, he also went into battle in person to refine some potion. Whenever Liu Yu personally refines the potion, it is when Qian Feixuan and other pharmacists are the most excited.

For them, every time they observe Liu Yu's refining medicine, it is a pleasure. Moreover, after this enjoyment, their own refining strength would often be improved.

Time passed quickly, and a week later, when Liu Yu was half-lying in the lounge of the small building store to take a break, his wrist-shaped brain sounded a communication prompt.

Liu Yu looked down, and when he found out that the communication application was sent by Mu Yan, he was slightly stunned for a moment.

Mu Yan didn't contact him much, and if it was okay, Mu Yan didn't seem to contact him to contact him or anything.

Now at this moment, Mu Yan will contact him, and it seems that it is only related to the fire attribute energy stone veins on the side of the mutant forest.

Liu Yu pressed the connect button on the brain, and then Mu Yan's beautiful face appeared in the virtual projection. Liu Yu's gaze swept over Mu Yan's face, and in just a moment, he felt that he was once again amazed by Mu Yan's beautiful face......

"Captain Mu Yan, you are really getting more and more beautiful." Liu Yu praised with a smile.

With a just right smile on his face, Mu Yan said, "Liu Yu, if you are saved with humans, even an intelligent life like you has become flamboyant." ”

Liu Yu also smiled slightly, and said: "No, no, no, I'm not flamboyant, I'm just saying my heart, every time I see you, it will make me feel amazing." ”

The smile on Mu Yan's face deepened slightly, she had never been praised for her beauty by any of her kind. And at this time, Liu Yu's praise made her feel very fresh, and at the same time, a faint sense of joy rose in her heart.

However, after all, it was an intelligent life, and Mu Yan didn't think much about it, and soon she brought the topic to the point.

"Liu Yu, I contacted you to tell you that the robot team I sent to the Mutation Forest to mine fire attribute energy stones has set off, and it is estimated that at night, it will be able to reach the location of the fire attribute energy stone veins."
