Chapter 275: Great Sound

Then they found some messy patterns in the lower left corner of the stone mural, which were completely invisible to ordinary people.

"It seems this is indeed a map left by our family. The one at the back is a proper guide, but the one at the front... is it meant to remind future generations of something?"

The mural in front looks like some unknown sacrificial scene. The general meaning is that there are many people playing musical instruments and offering sacrifices on the edge, and then walking into this place full of human-faced bird statues, and they will die if they walk to a certain place.

Zhang Moyu's eyes lightly swept across the first few pictures, and finally landed on the messy scratches. He decomposed those scratches in his mind, and gradually combined them into a rough map of the waterway.

Putting himself in the other's shoes, Zhang Benling looked a little strange and spoke in a low voice.

"The drawings above are too serious. I think it's more likely that one of them enjoys painting and was simply bored, so he doodled them during his break."

Things like the simple yet messy ones at the back should be useful things to draw.

It's not that he wants to slander his own family, but his own family knows his own business.

When it comes to serious matters, the words will be as concise as possible, and I would like to throw all the thoughts in my mind into the other person's head with just a glance.

Just like the one at the end of these paintings, a map made up of messy scratches.

At first glance it looks like something randomly drawn.

If you are not a family member, you cannot tell that it is a map, and even if you can see it, you may not be able to decipher it, which ensures the confidentiality of the information to the greatest extent.

As for the entire map, one only needs to calculate it in advance in the mind using the algorithm taught by the tribe, and those scratches can be carved out in a few seconds, saving time and effort, and ensuring high efficiency and confidentiality!

As for how hard it would be for later generations to figure out how to solve the map, and what to do if they weren't skilled enough and couldn't solve it, that wasn't something they considered.

"Tsk, our ancestors are really willful."

Hei Xia Zi, who thought he was now a member of the Zhang family, sighed first, and then spoke with dissatisfaction.

"By the way, the Zhang family's instructor didn't teach this either. You guys don't consider me, a blind man, as a family member!

You didn’t call me when you were teaching corpse language, and you didn’t call me when you were teaching map deciphering. If this keeps up, I’m going to make a scene~”

Hei Xia Zi's words were uniformly ignored by the Zhang family members present.

After all, they all knew that if they wanted to learn corpse language, not to mention the language talent required, the prerequisite was that they had to learn ventriloquism.

Ventriloquism requires a person to have extremely high control over their body. In the past, the Zhang family had very strict training requirements since childhood, and basically everyone could do it. But now, not even one out of a hundred can do it.

Not to mention the conversion method of Zhang family engravings from more than 1,600 to 1,700 years ago. The conditions are even more difficult to achieve. If you want to learn it, you must first learn the Qimen Bagua.

I don't need to be very skilled, but at least you have to be able to calculate.

If ventriloquism can be learned through hard work, then Qimen Bagua is something that requires complete talent.

Just like an ordinary person needs to write several pages of drafts to solve advanced math problems, while a genius only needs to calculate in his mind to get the answer.

If you don't have some talent, you may not be able to get the correct answer even if you rack your brains.

Now, apart from these old people in the Zhang family, there are only five people, including those from other families, who are proficient in Qimen Bagua.

Hei Xia Zi's complaints are purely unreasonable.

"Looking at the paintings in front, is the area with the human-faced birds standing in the arch used for sacrifice? You see, these people died when they walked into the middle. This area shouldn't be dangerous, right?"

After carefully looking at the mural, Wuxie put forward his own reasonable guess.

Although, they had previously said that this might have been drawn by a Zhang family ancestor out of boredom...

But what if there is some hidden information in it?

"At the sacrificial site, there are no fruits or musical instruments. All the human-faced birds face the central sidewalk. There are holes of uniform size on the birds' bodies. Anyone who walks into the middle will die..."

Zhang Benling summarized the points that he cared about in the previous paintings, connected them together, and had a vague guess in his mind.

"Is this... the great sound without sound?"

Zhang Moyu beside him nodded in agreement without saying much.

"What the hell are you talking about? The sacrifice of an eagle? There's no bird on this map. Do we have to find an eagle as a sacrifice to get through?"

The uneducated Fatty Wang cutely raised his questions.

On his left and right, Wuxie and Nan Xihe, both highly educated, covered their faces in unison and turned their heads away.

"Fatty, if you don't know, just shut up and stop exposing your ignorance. Others are full of knowledge, and you're full of... well, I've never felt that the word paunchy is so realistic."

Wuxie complained crazily. He felt that his good brother was usually very smart and clever, but it was his bad habit of always interrupting at inappropriate times and exposing his cultural level, which easily affected his image.

"This should be said that great sounds are silent and great elephants are invisible."

The clever Xie Yuchen pursed her lips and smiled.

He knew that sound could also kill people, and that sound frequencies that were too high or too low would have an impact on the human body.

Based on the clues in these pictures and the holes and placement of the stone statues, if it was a killing move, Xie Yuchen guessed that it should be the use of infrasound to kill people.

"Is it infrasound?"

Wu Sansheng suddenly spoke at this time.

He had to speak up. He hadn't found an opportunity to take action before. How long had he been ignored by others?

He felt that if he didn't actively participate and play a role, his voice in the team would become increasingly less.

He didn't join the team just to be a bystander. If this continues, they will not be able to proceed according to plan.

Although the current plan has been messed up...

But how could Wu Sanxing admit defeat? Besides, all the preparations made over the years couldn't go to waste.

"It's very likely, Third Master. You know, I used to be a soldier, and I heard about those infrasonic weapons when I was in the army."

Pan Zi echoed and tried hard to recall the original descriptions of his comrades.

"I've never seen this kind of weapon, but I've heard it's incredibly powerful. It's highly stealthy, has a wide range, is highly lethal, and is difficult to defend against.

I heard that infrasound can cause resonance in the human body's internal organs, leading to organ damage, bleeding, and even rupture.

In addition, it can also affect the human nervous system and psychological state, causing symptoms such as fear, anxiety, and nausea, thereby weakening the enemy's combat effectiveness."

Pan Zi's scientific explanation frightened Wuxie and the other young people.
