Listened to this. Xu Yuanyuan looked at the position pointed to by Xiang Dongliu, and really found that the left chest of this corpse had a logo of the Mares diving brand, so she understood that this corpse was most likely Xu Jinzong's father.

However, there was nothing on or around the corpse, suggesting that the note they were looking for might have been lost.

In this regard, Xu Yuanyuan couldn't help but have the courage to go over and move the corpse away from its original position, and then suddenly found that there was something strange in the mud and sand that the corpse was originally covered, so after reaching out and picking it up, she immediately found a palm-sized black notebook and a pen clamped on the notebook.

It's just that the pages and pens of this black notebook are not regular pen and paper.

The pages of the notebook are made entirely of plastic, but the tip of the pen is a delicate steel needle. When writing, use a steel needle to make a mark on the smooth page of the plastic material, so that it does not get soaked in the water under the natural cavern when writing on the paper with ink.

In other words, this should have been prepared by Xu Jinzong's father in order to cope with underwater writing.

"Good fellow, what the hell did his dad write, why can't I read it at all?"

Xiang Dongliu took the notebook from Xu Yuanyuan's hand and flipped through it, and suddenly said in confusion: "It feels like an engraved astronomical symbol, it looks very mysterious, not like an expedition note at all?" ”

"Perhaps...... It's a special kind of password, right? ”

Xu Yuanyuan couldn't help but point to a symbol on the page, and said thoughtfully: "It's like this symbol may represent a word or a sentence, so if the words represented by all the symbols are connected, it should be a complete article." ”

"Khan, wouldn't it be too exaggerated?"

Xiang Dongliu cried and laughed: "If the truth is really as Sister Xu said, then this Xu Jinzong's father must be trying to hide something!" ”

"Or else?" Xu Yuanyuan spread her hands and said, "If it is just to recover my father's body, I estimate that Xu Jinzong is still reluctant to spend tens of millions of capital to ask us to do things, so the most likely situation is that Xu Jinzong's tens of millions of expenses may be an investment, and the purpose is the information recorded in this black notebook." ”

"Don't worry about it yet! Keep exploring! ”

Xiang Dongliu quickly put away Xu Jinzong's father's personal notes, thinking that if there was really a secret hidden in this notebook, wouldn't it be better to find a free time to copy a research study after completing the task?

Anyway, now, I can't see anything famous when I look left and right.

After a slight pause, Xiang Dongliu and Xu Yuanyuan temporarily put Xu Jinzong's father's body in its place, and continued to investigate in this unknown second area.

I have to say that in this second unknown area, there is indeed a bit of hidden danger.

Because, Xiang Dongliu and Xu Yuanyuan can actually see a rotten corpse or even human bones from time to time, which shows that since a long, long time, many people have come here one after another but ended up dying!

If you look at the water quality alone, it is certain that it is not poisonous when it flows eastward, but why did you come here and die? And there are quite a few of them! Why do they continue to follow each other like moths to a flame?

Xiang Dongliu and Xu Yuanyuan came to find the perspective treasure mirror, but before the owner of the perspective treasure mirror, there were already many people who had turned into bones here! What does this mean?

Through a few simple wound investigations, Xiang Dongliu found that the dead or rotting corpses could not find any blunt objects or wounds attacked by ferocious creatures, so he felt that the cause of their death seemed to be too strange.

Even those white bones couldn't see any cause of death, which really made Xiang Dongliu and Xu Yuanyuan feel a little creepy unconsciously, as if they had come to a cursed place of death.

In fact, if a strong enemy or an extremely dangerous creature appeared in front of Xiang Dongliu and Xu Yuanyuan, they would not be so afraid.

But it was this unknown danger that made them immediately realize that this second area was far from being as normal as it seemed!

"What the hell killed those people?"

Xu Yuanyuan frowned, and immediately told Xiang Dongliu: "You have to be careful, if something is wrong, it is safer to retreat in time." ”

"Don't worry, I'll pay attention."

Xiang Dongliu nodded seriously, but suddenly guessed: "Sister Xu, do you say that there are other treasures or treasures hidden in this second area?" Otherwise, how could so many people come one after another? ”

"Although we say that we are also for the baby, the crux of the matter is that before the owner of this see-through treasure mirror came here, there were already many people here! This shows that they are not here to see through the treasure glass! ”

“…… Don't you patronize and think about it, baby, okay? ”

When Xu Yuanyuan heard this, although she also felt so, she was even more afraid of the unknown danger, so she told again: "The people here don't know what they have been killed, if we don't find out or avoid this danger in time, maybe we will end up like these people!" At that time, this second unknown area will really become a veritable burial place! ”

"What is certain is that the source of this unknown danger is definitely not people!"

Xiang Dongliu gently stroked the surface of the Soul Ring, and immediately searched for the inner thoughts of people nearby through the magic of long-distance listening through the Mind Ring's long-distance listening.

In addition to Xu Yuanyuan's inner thoughts, Xiang Dongliu actually heard the two axes, and then there was no one else.

This means that all of the two axes' men may have been killed by the piranhas, and there are no other humans in this second area!

"Is it poison?"

Xu Yuanyuan guessed: "But the experience I learned from the forensic doctor earlier shows that after the poisoned person dies, his bones will actually become a very different color, and it will not be as normal as the color of the white bones of these dead people now." ”

"Don't worry about it yet!"

Xiang Dongliu lowered his head and shook the rotting corpse and said, "Sister Xu, pay attention to the faces of those dead people, as long as you have glasses, take off your glasses!" After all, I've never seen a real see-through mirror, and I don't know what it looks like. ”

After saying this, Xiang Dongliu suddenly grabbed his right hand tightly with his left hand, and almost cried out in pain.

Because, he found that the frequency of alternating between hot and cold before the Mind Ring had gradually accelerated over time to a very rapid situation, which caused the pain he was suffering to skyrocket several times.

However, Xiang Dongliu didn't tell Xu Yuanyuan the slightest, he just wanted to endure the pain first, and find the perspective treasure mirror and leave before the soul ring really evolved.
