"Senior brother, it's time to eat." Yun Rou's voice came from the door, the voice was very soft, and there was no knocking on the door or using sound transmission, so that if Feng Xue was at a critical moment, she would not be interrupted by this level of calling, although it was only a little detail, but it showed Yun Rou's carefulness.

"Here, what do you want to eat today?" Feng Xue answered, then put on her coat and prepared to go out, there is no way if she doesn't go out, Feng Xue herself can only make noodles, Yunrou's instant noodles are still learned from him, as for Yunlan, as a sister who was born after eating brown rice and salting for decades, do you expect her to cook?

"Didn't you say you would eat all the way along the food court?" Yunlan, who changed into civilian clothes, pursed her lips, looking at the way she couldn't chat, she was out of character again.

"......" Feng Xue was choked for a moment, but she didn't take it to heart, "Then let's go eat the yellow braised chicken rice bowl today, by the way, what level of attack can you use the piano without using the true yuan?" ”

"Probably to the extent that a mortal is frozen to death by sound alone, right?" Yun Lan stated the terrible truth without any emotion.

"So you almost killed thousands of people through the screen yesterday?" Feng Xue suddenly felt that she was still a little careless, which was no less than carrying dozens of tons of flammable and explosive materials in and out of the gas station, and by the way, she also lit a cigarette!

"No, I looked at the video later, and found that after passing through that magic weapon, there are some sounds that can't be truly reflected, so the effect will be reduced by about three to fifty percent, even if I go all out, at most it will make the people behind the screen infected with wind and cold." Yun Lan shook her head, which was regarded as a reassuring shot for Feng Xue.

"Forget it, I'm not asking about spirits or illusions, but physical attacks, can you do it without using true element power?" Feng Xue has already said that he feels that he is a strong man, martial arts novels are just novels after all, and they have to rely on the piano to play the vacuum blade or something, and it is impossible not to rely on supernatural powers, right?

"......" Yunlan was silent for a moment when she heard this, as if she was calculating something, and after about two minutes, she nodded, "It may not work at a long distance, but if it is within ten meters, you should be able to boil a glass of water......

"How does this work?" Feng Xue had a strange look on her face, "Why water?" ”

"The essence of sound attack is vibration,After excluding the interference of sound on human consciousness (including souls, hormones, psychology, etc.),Vibration is the only means of killing sound attack,Back then, Miao Yin Pavilion once lost to the Forgetful Sect that can isolate their emotions (similar to the mechanical mind,Shielding the influence of hormones on emotions) in the cultivation world,So I have worked hard in this regard,If you use the true yuan force to assist,You can beat your target into powder thousands of miles apart,But simply use the sound rhythm, Without the increase in true elemental force, it is not enough for the solid to produce sufficient vibrations, and the gas is not powerful enough under low-frequency vibrations, and if the calculations are in place, it should be able to boil the liquid in the quilt. Yun Lan explained simply, I have to say that this group of cultivators is more scientific than imagined!

But......

"If you can boil water, can't you burn it all together?" Feng Xue didn't know how many times this was the first time he had raised the level of danger in his mind from this group of cultivators! Even if the real yuan is banned, can you keep making trouble?

"Impossible!" Yun Lan waved her hand as if she had heard a joke, "Although most of the human body is water, the vibration frequency of blood, water, muscles, and bones is different. ”

"I see." Feng Xue was somewhat relieved, this was actually the same as putting a straw in a water cup that would not be easy to spill, but speaking of which, Feng Xue suddenly liked that method to increase the effect of the performance-

"That, Yunlan, you try this, if you can make the liquid in it boil, maybe you can put on a new show tomorrow."

"What is this?" Yun Lan watched Feng Xue take out what looked like a cup from the refrigerator, and it looked like there should be a lot of liquid in it.

"A drink." Feng Xue didn't explain much, because once it comes to Coke, you have to talk about carbon dioxide, and when it comes to carbon dioxide, you have to explain what this thing is for, instead of being so troublesome, it's better to just say a rough idea, let Hou let Yunlan check it himself, anyway, he has already learned to use a computer, isn't it?

"Let me study what's in it first, water and drinks don't shake the same way." Although Yun Lan said this, Feng Xue always felt that her eyes were full of three big words: "I want to drink".

"Okay......" Feng Xue opened the can and poured it into the cup and handed it to Yun Lan, and by the way, he took another can to Yun Rou, not that he insisted on treating people equally, but because Yun Rou's eyes were about to stab him, if he didn't give it again, he was afraid that Yun Rou would give him small shoes.

"Uh-huh, I see, is there a gas flush in the liquid? So the gas will come out of the heat after heating, are you trying to use this to make the sealed jar explode? Yunlan took a sip of Coke, a smile appeared on her face, and she didn't know if she was satisfied with the drink she tasted for the first time, or if she had simply found a solution.

"That's pretty much it, can you do it?" Feng Xue nodded in affirmation.

"How so? It's so much easier than I thought! Yun Lan put the half-drunk Coke on the table, thought about it, drank most of it again, leaving only a small sip on the table, and then summoned Xing Lanqin and played it quickly.

This time she didn't play an existing repertoire, and it wasn't an improvised piece, but a series of individual notes out of tune.

Obviously, this is Yunlan auditioning.

With Yun Lan's attempt, the less than centimeter-tall cola in the glass began to ripple, and then as if it had been thrown into Mentos, it turned into gray-brown foam and swelled, and in an instant spewed out of the rim.

"It's finished?" Feng Xue raised her eyebrows, a smile on her face.

"Well, I almost understand, give me that jar, although it looks thin, but if you want it to explode, you still have to study it." Yun Lan seemed to be a research madman at this time, staring at the subject in front of her intently, and even forgetting to eat, but she would forget, but there was someone who wouldn't, just when Yun Lan and Feng Xue were chatting energetically, Yun Rou had been changing her clothes for a long time, although she was still standing there quietly, but she always felt that her smile had changed strangely......

"That, Senior Sister Lan, let's go eat first, shall we?" Feng Xue finally felt the piercing gaze, shook her spirit, and then said in a good way.

"Ahh Okay, I'm pretty much there, this thing is more fragile than I thought......" Yunlan nodded, casually throwing the jar aside, the next time belongs to food!
