"Click, click, click......"

Lin Feng walked to the end of the corridor again with unhurried steps, and to his slight surprise, as soon as he walked in front of the metal door, the electronic system on the door sounded a warning sound.

"Drop! Identity, please do not approach without permission!"

I rub!

Lao Tzu is just passing by, do you need to be so sensitive?

I saw Lin Feng frowning, and then decisively took a step back, so the electronic system on the metal gate immediately fell silent.

Damn!

Lin Feng glanced at the metal gate with disdain, then touched his chin and pondered, why did Lao Dong lie to him? There are obviously more than three floors here, why doesn't this guy tell the truth?

Isn't the fourth basement floor an infrasonic practice room?

If it wasn't an infrasonic practice room, what would it be?

Forget it, since Lao Dong didn't say it, Lin Feng didn't bother to ask, now, let's try the specific effects of the infrasonic training room!

......

Glancing at the room located on the third basement floor, Lin Feng suddenly rolled his eyes, and then strode to the door of an empty room, and then took out his agent card.

Swiped the agent card to the electronic screen on the door, and after hearing a soft sound of 'drip', an electronic synthesis sound immediately sounded.

"Comrade Lin Feng, your contribution value balance is insufficient and you can't use this room!"

All right!

Lin Feng is greedy!

10,000 contribution points and want to use the advanced infrasonic training room?

Is it really an idiot to be the intelligence system of the base?

Liver pain!

......

Returning to the basement floor, Lin Feng honestly found a vacant room, then paid 10,000 contribution points, and finally brushed open the door and walked into the legendary infrasonic cultivation room.

This infrasonic training room is not large, only about 30 square meters, and the floor, walls, and ceilings of the room are all made of metal materials, which looks very good for sound insulation!

However, there was only one sink and a chandelier in the room, and as for the table, chairs, sofas, beds and the like, there was none!

Damn, it's like a prison cell, I'm completely sorry for the luxurious decoration in the corridor!

I saw a trace of contempt in Lin Feng's eyes, and then he gently closed the door, who knew that at the moment when the door closed, another electronic synthesis voice sounded in the room.

"Welcome Comrade Lin Feng to use the No. 027 infrasonic training room, now, the infrasonic function has been officially turned on, and after 24 hours, the system will automatically turn off the use function of this room......"

Lin Feng didn't have time to listen to the voice broadcast, and the moment he closed the door, a wonderful feeling immediately came to his heart.

It felt as if someone was playing a drum in his ear, not only did it make Lin Feng's cells jump all over his body, but even the destructive power lurking in his body suddenly burst out!

"Whoosh!"

Seeing that Lin Feng didn't say a word, he immediately rushed to the center of the room, and then quickly sat down cross-legged, and then closed his eyes and sensed it seriously.

"Buzz, buzz, buzz......"

The frequency of infrasound waves was very low, but Lin Feng still heard the sound they made under careful sensing.

"Bang, bang, bang......"

Lin Feng's heart was beating regularly with the rhythm of infrasound, and at the same time, the destructive power in his body was also circulating rapidly along a specific route.

Infrasonic waves are directing the forces of destruction!

The forces of destruction are mimicking the rhythm of infrasound!

At this moment, a flash of realization suddenly flashed in Lin Feng's heart, perhaps, the destructive power is also rhythmic!

It's not a hard ball of energy, and it's not just a matter of using it to give it its desired effect!

If the rhythm of it is well controlled, like infrasound, is used according to specific laws, then the power of destructive power will be even higher!

Hiss!

So, what kind of rhythm is suitable for destructive power?

Do you want to give it a try to the rhythm of infrasound?

Just do it, Lin Feng immediately activated a trace of destructive power, not much, about 1%.

I saw that he learned the frequency of infrasonic vibration, and blasted this wisp of power out, only to hear a 'poof', and this force immediately dissipated after hitting the wall.

Hey?

Why does it seem to be weakened?

Could it be that the rhythm of this destructive force is infinitely close to infrasound, and at this moment, the room is almost entirely filled with the frequency of infrasound, so the power of destructive power is neutralized?

Wrong!

It shouldn't be like that!

Why don't you try to change the rhythm of the destructive force?

So, in the following time, Lin Feng tirelessly started experiments.

I saw wisps of destructive power being transferred out of his body by him, and then bombarded the metal wall again and again, each time the lethality caused was different, and each time Lin Feng would gain some experience.

Time passed minute by minute, and when Lin Feng attacked the wall with his destructive power for the Nth time, an electronic synthesis prompt suddenly sounded in the room.

"When the time for this practice is up, Comrade Lin Feng is requested to leave room 027 within ten minutes. ”

I rub!

24 hours have passed so quickly?

Is there a mistake?

I saw Lin Feng quickly take out his mobile phone and look at it, the time has indeed passed 24 hours, this Nima is too fast, right?

No wonder it is often said in fantasy novels that cultivation has no time, thousands of years in a blink of an eye, Lin Feng simply experimented with the rhythm of the destructive force, and 24 hours passed in the blink of an eye.

If you sink your mind and comprehend the power of destruction, wouldn't it be a moment of closing your eyes and then opening your eyes, and your whole life will pass like this?

Although it wasn't that exaggerated, Lin Feng couldn't help but vomit, only to see him take a deep breath, then close his eyes and sense for a while, and finally shook his head helplessly, the infrasound in the room was really turned off!

All right!

A day has passed, and 10,000 contribution points are really unspent!

......

Taking advantage of the fact that there were still 10 minutes left, Lin Feng carefully studied the door lock of the room before leaving the infrasonic practice room.

Don't ask why?

Because Lin Feng can pick locks!

Isn't there a saying that says very clearly? If you are not afraid of thieves stealing, you are afraid of thieves and will be worried about them! But when this sentence is changed to thieves, it becomes: If you are not afraid of what you don't steal, you are afraid that you don't have anything to worry about!

Lin Feng, this is thinking about the last sonic training room!

However, just opening this door lock is not enough, the intelligent system of the base is not dry, without the verification of the intelligent system, even if Lin Feng opens the room, he can't turn on the infrasonic function!

Never mind!

In addition to being able to pick locks, Lin Feng is also a top hacker!

As long as you find a way to hack into the base's intelligent system, won't you be able to walk sideways in the base?

Rattle!
