Looking at Kavina who looked serious, Fu Yun quickly exclaimed: "Oh my God! I said Nana, you are right, the molecules of steel are arranged very closely, are you okay?"

Kavina shook her head and said, "Try it. As you said, the molecules of solid are generally arranged in very neat and orderly, and the gap between molecules is very small, especially steel. The molecules are arranged in a very tight manner, so it is so hard. But one thing you should also note is that the speed of sound propagation in the solid is much greater than that of liquid or gas, and the greater the density of the solid, the faster the sound propagation... And now, what I have to do is find its natural frequency, and then use high energy to make it produce high amplitude resonance, which intensifies its molecular movement and leaves its original position, so that it can dissociate without changing its three states."

Speaking of this, Kavina took a deep breath before continuing: "But I have to control the range of vibration. If the range is too large, it will not have any effect at all. Maybe it will attract the attention of the enemy. So help me see the situation outside, and don't touch my arms no matter what happens..."

Don't touch her arms?

Fu Yun couldn't help but leave a trace of cold sweat. In fact, the principle of sound waves was that they were originally from the vibration of objects, but now she had to use her arms as a shock absorber, and this required very precise control of the vibration frequency, which was far less simple than the vibration effect generated by a casual wave of a white beard.

Resonance can destroy all objects, but one can destroy oneself if one is not careful.

"I didn't expect you to know so much about the characteristics of sound waves." In order to break the cold atmosphere, Fu Yun said teasingly.

"Haha... Actually, I don't want to do this either."

Kavina also cooperated and smiled: "At first I just wanted to cure my disease, but then I found that the more I use my abilities, the worse my body will become, unless I give up my abilities."

Fu Yun sighed and said, "Actually, there is a way..."

Kavina looked at Fu Yun, smiled slightly, and interrupted softly, "I know what you want to say, it doesn't matter, I believe in you."

Fu Yun also looked at Kavina's lively eyes and stopped talking silently. Although Fu Yun was not clear about Kavina's fruit level, one thing that could be confirmed was that it was completely inconsistent with her current character level, that is, her fruit level was much higher than her own level.

First of all, if a person's fruit level is not enough, he will not be able to use this ability to defy the will. Secondly, if a person's own level is not enough, he will not be able to use such ability.

For example, after being obtained by ordinary players, they cannot achieve the effect of a white beard. Even if they use the effect of a white beard, their bodies cannot bear it. They either leave permanent trauma, or their bodies will be shattered together.

Of course, there is not only the character level, but more importantly, the character's own attributes that have been raised by various experiences. The ordinary players at level 120 are completely different from the Whitebeard at level 120.

...

After pondering for a while, Fu Yun couldn't help asking: "How confident are you? Don't force it."

"That's right." Hearing the conversation between the two, Anne said worriedly: "Or, I think it's better to forget it. It's just a door. If we can't enter, we won't go in. There is no need to make such a big sacrifice, which is like separation from life and death."

Kavina also laughed out loud and said, "Where do you want to go? To be honest, I have no idea at all, but I just want to try it. If it doesn't work, I will stop at any time."

"Okay." Fu Yun finally nodded and said, "You must be careful, and don't hurt yourself."

"Yeah, don't worry."

“…”

It was not until this time that Annie slowly breathed a sigh of relief, putting her hands on Kavina's back, and the fruit ability was activated, and liquid like water penetrated into Kavina's skin through Annie's palm.

Kavina slowly closed her eyes, and then Fu Yun felt the airflow around her tremble, and an invisible sound wave spread, as if the entire base wall was trembling.

...

Deep in the base, in the dark passage, soldiers sat back to back together in groups of three or five, vigilantly checking around them. Many people were seriously injured and even though they were injected with anti-toxic serum, they still fell asleep completely.

These people will never forget the scene just now. The black and white zebra patterns surged wildly on the ground. Each one was like a death-seeking god of death. Being bitten by a bite would be equivalent to being sentenced to the end of life.

But it is this kind of horror that is like Bitao, who puts himself and his people in the middle. If the two school generals had not fought desperately with the elites at the headquarters and the timely healing of the doctor team, there would be absolutely no possibility of them surviving.

So, at this moment...

People's eyes at these two school generals are no longer just about gratitude and awe, but more about something from the heart.

"Colon Terron, you are not in good spirits. There are still extra potions here. Why don't you inject one for you?" A nurse wearing a white cloak behind her walked to Terron and asked with concern.

It has to be admitted that after the naval uniforms are matched with nurses' professional clothing, the effect of the combination is as simple as a uniform. This nurse is particularly different from other nurses dressed in pink. It can be seen from her cloak that her military rank should be above the school level.

Coupled with the combination of short skirts and stockings, countless ordinary soldiers burst into glasses, and some people were even more envious of them and almost even saliva stayed.

But Tyron seemed to have seen nothing, and forced his heavy eyelids as heavy as ten thousand pounds, waved to the beautiful doctor beside him, "It's okay, I'll inject all these into those unconscious brothers. They need them more than me."

"But... Colonel Tyron." The doctor pursed his red lips tightly, hesitated, and said with some difficulty: "We have given them double doses. Now they are still sleeping, which only means that these drugs cannot produce antibodies in their bodies, and... their breathing has begun to be paralyzed and become weaker and weaker..."

In the end, the doctor's voice was getting smaller and smaller, and it was too small to hear. Although this was for everyone to consider, because there were more unknown dangers later, so they did not save some, and they would reserve more hope for life for everyone, but after all, this was to leave behind the words of their companions.

On the other hand, Colonel Tyron suddenly opened his eyes wide and stood up suddenly. The beautiful doctor who was so scared that he retreated repeatedly and almost fell to the ground.

It seems that Colonel Tyron really cherishes his subordinates as he said outside, but the thunderous rage that the beautiful doctor expected did not appear. Colonel Tyron just walked towards the wall on the left in silence, then gently put his hand forward, and after looking at Major Blanu, the two of them shook their heads at the same time.

"Terron University... School? Are you okay?" asked the beautiful doctor with some anxiety.

Colonel Tyron slowly turned around, and if his eyes had not appeared at all, he sighed: "It's okay. I should be too tired."

...

In the underground secret passage, a naval doctor with a strange appearance, suddenly looked up and looked at the ceiling above his head for a long time. Then he gently stroked the black creature on his left hand. His voice was so gentle that it made his scalp numb, and he asked, "Little baby, have you heard any strange sound just now?"

The black creature spins on the Navy's hand for two weeks, making a "chiji, schiji" sound, and then the monster immediately smiled and said, "Yes, it's my fault. You don't have ears, so you can't hear it. Then do you feel any strange fluctuations? Oh? Is that? Well... I understand."

...

Although the fluctuation on the ground passage did not make any sound, it continued over time and spread from afar. The obvious tremor really scared Fu Yun.

"It seems that it won't work." Kavina shook her head in disappointment and said, "They seem to have discovered the situation here just now. It seems that we have to think of other ways."

Fu Yun also frowned slightly and said, "Try it again. The frequency has been determined now, so don't last for that long, and try to let the vibration hit some."

Kavina coughed softly, then nodded, put her hand on again, without the prelude just now, and directly released the resonant frequency of the steel.

The air was obviously rhythmic, and Fu Yun also felt as if he had illusions that there were obviously wrinkles on the wall in front of him. However, the subsequent situation was the same as before, and the wall returned to calm. Just as everything had happened, Kavina immediately let go, not allowing the wave to spread too far.

"It's still not possible." Kavina's face felt a little more disappointed. She covered her mouth with her hands, and her cough became even worse.

Just give up like this?

Fu Yun believes that he does not have such a habit, and he doesn't like the feeling of failure. And once he can break through the steel, it can be said that Kavina's strength will also make a qualitative leap.

Fu Yun turned around and said softly: "You have a rest first."

"Um."

“…”

Looking back on the fold just now, it was like the waves of water spreading out layer by layer in Fu Yun’s mind, but why? Why did the water surface return to calm?

It is this feeling of vagueness that makes Fu Yun want to catch it, but he can't catch anything. Stones, fluctuations, water surface, stones fluctuations, water surface, stones...

"etc."

Fu Yun suddenly stood up and said with a smile: "I understand, the key to the problem lies in the stone."
