At night, the fiery Luo Yuan went to three battlefields in a row, and made the three girls paralyzed like mud, proving with practical actions that this month, his body was still loyal and he was not seduced by beauty.

Despite his strong physique, even four or five times a day, he is still fierce and radiant.

……

In the early morning of the next day, Luo Yuan got up quietly, got dressed, took the horse chopping knife, and walked out of the underground city.

At this time, the sky was not yet light, the night was hazy, and only the factories on both sides of the day and night emitted dim lights.

There are no street lights in the apocalyptic ground cities, firstly, to avoid the attack of phototaxis mutant creatures caused by the lights, and there is also not much energy to waste.

Luo Yuan took a deep breath of the cold air mixed with the exhaust fumes of various factories, and the strong pungent smell made him sneeze, he was refreshed, and then quickly ran towards the field along the street that was mottled and potholed by the large-tonnage heavy truck.

The speed is like light and shadow, setting off endless winds along the way.

Ever since the scrapping of that floating tracksuit, every time I run, it always causes a strong wind and looks extremely violent.

The air, which is almost unhindered to ordinary people, is close to the liquid in the face of a speed close to subsonic, and every step forward requires a huge amount of force, and the speed has reached his level, almost approaching the limit, and every meter faster has become extremely difficult, and the air resistance has increased geometrically.

It is conceivable that in order to break through the sound barrier, he would have to be three or four times stronger than he is now, and the same would be required for agility, and taking into account the effect of air buoyancy, the running posture must be lower, close to the ground, and the buoyancy must be counteracted by the downforce of the air.

However, this is only an ideal state, after all, man is not a machine, can not conform to fluid dynamics like FI racing cars, he needs two legs to run, his eyes also need to observe the four directions, and pay attention to the terrain, too low posture, will cause great obstacles to running.

He estimated that if there was no equipment such as a floating suit, which could counteract drag, or if there was a leap of will, his speed limit should stop at subsonic.

Of course, this limit is only for long-distance runs, and short-distance bursts within one step are not included.

……

Ten minutes later, Luo Yuan came to the Gobi Desert, which he had visited several times, and since discovering here, this undisturbed Gobi Desert has gradually become his personal training ground.

However, this time he came, it was not his usual sword practice.

After returning from Xinjing, he has been haunting a thought in his heart, but he has not had time to experiment, and after venting his anger at night, his mind is clear, and the original rough thoughts have gradually become perfect, so before dawn, he can't wait to come here to test his ideas.

Ever since he became an Evolver, Earth Pulse has been his most powerful tool, if not his last card, for some time.

However, as his strength has become stronger and stronger, the earth pulse has gradually become dispensable, like chicken ribs, especially after discovering that it can heal itself quickly through the will, and even the healing of the earth pulse does not need the earth pulse, and the effect is better and faster.

As an evolutionary, Luo Yuan is already a little unworthy of his name, perhaps only the additional physique, which is now as high as six points, shows Luo Yuan's identity as an evolutionary.

If it was before, he hadn't thought about it before, and he didn't have any concept, plus his own strength was also strong, so he didn't use it much, and he never thought about redeveloping his evolutionary ability.

This trip to Xinjing can be described as a lot of harvest for Luo Yuan, the knowledge obtained is only the surface, but the inside is the expansion of vision, the transformation of thinking, no matter how smart a barbarian, he is still a barbarian, his vision and habitual thinking limit his ability and development, maybe there is an occasional inspiration, groping out some fragmentary experience, but from a higher point of view, he still has not broken the trap, has been going around in circles.

……

The role of knowledge is that it can often leverage greater force with the least force.

Mechanical waves propagate through vibration, and earth pulsation is also a kind of mechanical wave, which transmits energy through earth oscillation, and the essence is the same as a pebble thrown into a lake, forming a circle of ripples.

When the earth pulsation is activated, with the help of the power of the earth, the energy is majestic and the momentum is amazing. However, due to the wide range of action, the energy is extremely divergent, resulting in the strength of the attack, which is somewhat unsatisfactory.

In the face of low-level mutant beasts, the natural effect is outstanding, but now the enemies that can pose a threat to Luo Yuan are basically at the seventh level, such a giant beast is huge in size, and the tonnage is amazing, like a body as long as a hundred meters like a soul eater, if you use earth pulsation, it is like a mayfly shaking a tree, it can't be shaken at all.

If you can focus the fluctuating energy together and concentrate a little excitation, it will definitely exert great power.

This is undoubtedly quite difficult, like a stone thrown into a lake, it does not ripple, but forms a column of water nearby, and this column of water cannot be formed randomly, the position must be precisely controlled, otherwise it will not work at all.

It wasn't until he came out that he had a perfect plan in his mind.

……

His heartbeat slowed down slowly, and in just a few breaths, he had already entered a state of earth pulsation. The distracting thoughts in his mind quickly emptied, the expression on his face disappeared, and his gaze became rational and indifferent, without the slightest emotion.

He could feel the movement of the earth, with an eternal ancient atmosphere, and at the same time it contained endless power, majestic and vast, heavy and quiet, like a long-suppressed volcano, ready to erupt at any time.

His eyes were half-open and half-closed, slightly brewing, and then the momentum was emitted with all his might, and in an instant, the flow of air instantly froze, and a terrifying aura spread, and there seemed to be an invisible force enveloping this space, and countless gravel and fine sand began to tremble violently, and they were suspended one after another.

In the meantime, there was a subtle electric light, flames were born out of thin air, under the shroud of will, this area within a radius of 100 meters seemed to have turned into his domain, and as his thoughts were born and died, various energies stirred each other in the field.

Since the last upgraded skill point raised the knife expert to 7 points, with the memory and perception given by the system, after several months of non-stop practice, he has gradually felt this feeling.

After a while, as Luo Yuan's thoughts calmed down, everything became calm, and even the gravel and fine sand began to fall slowly, but faintly, there seemed to be a stronger storm, which was about to move, and it was not triggered.

didn't wait long, Luo Yuan began to move, and he suddenly raised his feet.

Stagnation and heaviness!

In a trance, the earth seemed to shake, and there was an illusion that the whole earth was being lifted.

The next moment, the foot hit the ground instantly!

In an instant, like a muffled thunder explosion, the earth seemed to roll, suddenly violently shaken, a large amount of sediment mixed with the weeds that were shattered by the shock, rushed to five or six meters high, and even with a Gobi not far in front of it was more than ten meters high, it also seemed to have suffered a heavy blow, suddenly collapsed, and a large number of boulders rolled down to the ground.

Luo Yuan frowned slightly, stood motionless, and groaned secretly in his heart.

"This experiment was not successful, but it was not a failure, looking at the collapsed Gobi, it shows that the shock can be controlled, but unfortunately this time the control is not perfect, nearly two-thirds of the energy is leaked."

"We need to continue experimenting."

This piece of Gobi, like a stone forest, has stood in the desert for tens of millions of years, but with Luo Yuan's thoughts, it began to usher in a catastrophe, and the Gobi collapsed from time to time, causing a cloud of smoke and dust.

"The will is too weak to fully control such a huge amount of energy, but it seems that there is no need to fully control it, the will only needs to act as a springboard, one end falls, and the other ends." Countless data flashed through his mind, and he secretly said in his heart.

"The effect of the will is only in the moment of energy release, and the strength itself does not matter, in this way, the consumption of the will can be saved by half, and there is more spare power to control the leakage of energy!" He said secretly in his heart, and his eyes looked at the Gobi in another place.

He experimented again and again, adjusted again and again, and the leaked energy decreased at a rate visible to the naked eye.

Eventually, his realm had completely dissipated, and his control over energy had become more subtle.

In the end, he looked up at fifty or sixty meters away, the highest and largest Gobi with a radius of more than ten kilometers, this Gobi is fifty or sixty meters high and about 100 meters in diameter, and from a distance it looks huge and almost like a small mountain.

There was a gleam in his eyes!

Instantly lift your legs and fall!

"Boom!" With a loud bang, a circle of dust spread out in an instant like a shock wave, but except for the dust, the surrounding earth did not cause the slightest agitation, Luo Yuan glanced around, and then looked at the Gobi that had erupted into smoke and dust.

It's a pity that this Gobi is too heavy, roughly estimated at 780,000 tons, even if all the energy is applied to this Gobi, except for shaking off some dust and rubble, it still stands.

However, he had expected this outcome in his heart, and he was not disappointed.

He was already satisfied enough to be able to shake this hill slightly, and this kind of earth fountain, in addition to the impact, also had a terrifying high-frequency shock, he could completely imagine what kind of fate would happen to the seventh-level mutant beast with such an energy impact with its flesh and blood!

……

At this time, the sky was already dark, and an hour had passed in a blink of an eye, feeling that his perception and will had been greatly consumed, and there was not much left, Luo Yuan frowned slightly, and had to withdraw from the earth pulsation state.

The earth fountain is just one of his ideas, and there are more effects of fluctuations, such as resonance, such as superposition, but unfortunately they can't be experimented one by one in a short time.

The former needs to understand the frequency of the earth, and every time the earth is trampled, as a vibration, through resonance, to cause an earthquake, this frequency is not the earth pulsation, the earth pulse is the frequency of the entire planet, including the crust, mantle and the center of the earth, the synthesis of the frequency of the three, specific to a small area, because of the different geology, density and terrain, have their own different frequencies.

Of course, even if he was mad, it would not be possible to shake the entire earth by forming a resonance with the frequency of the earth's pulsations. Because the earth's crust at different frequencies will not wait for the resonance to form before it completely absorbs energy.

He was able to attract only a small area, which can be as small as a few kilometers or hundreds of kilometers depending on the degree of variation in the surrounding geology.

He had the intention to experiment, but unfortunately this land, the plates are too fragile, and there are still small earthquakes from time to time, he can't estimate the consequences of the resonance, if it induces a previous big earthquake, it will be too late to regret it.

And the latter, but because the frequency of the earth trampling is too high, it is almost a thousand times per second, even his fifteen points of agility can not be clearly distinguished, not to mention that the duration of the peak of the shock is only about 0.1, and then the energy quickly slides, in order to form a greater power, he must trample the earth twice in a row in such a short period of time, and the fluctuations of the earth trampling must coincide, crest to crest, trough to trough.

The difficulty can be imagined!

This is not taken into account, two consecutive oscillations, the difficulty of controlling the energy is almost a geometric increase in difficulty.

Maybe wait for his agility to improve by one or two points before he can try to start experimenting, but the advantage of superposition is that as long as he can keep up with his agility and energy control, the power can be increased endlessly, and the power of two superimpositions is not enough, it can be three, even five times, ten times.
