He didn't go far, Tang Juyi came to an open place, where a large instrument that had been damaged was placed, judging from the appearance, it should be some kind of detection equipment, and it was also marked with the mark of the Phil family, which was obviously from that expedition team.

"They had this instrument installed to measure data or detect something...... But it was destroyed. ”

Tang Juyi walked around the instrument twice and came to an unexpected conclusion:

"This is a trace of vandalism!"

The structure of the instrument was quite sophisticated, but now it was dented in many places, and it had been split with several irreparable fractures, which seemed to have been caused by cutting with a sharp object.

At this moment, Tang Juyi thought of the axe in the submarine "Starling Snail".

"Could it be...... Did they do it themselves? They spoiled their own arrangement with their own hands? But why do you do that? ”

Tang Juyi looked around, except for a few lamps inserted in the rocks that had lost their power, there was only a simple camp set up near this instrument.

There was a pile of damp char in the center of the camp, presumably a campfire lit by the expedition members, and some food bags were left in the small tent next to it, and it seemed that they had lived here for a while.

After wandering around the improvised camp for a while, Tang Juyi was not able to find any clue items such as diaries, but found some unusual ashes in the pile of charcoal.

Judging by some of the unburned parts of the ashes, a large stack of paper had been thrown into the campfire.

Tang Juyi wanted to find something out of the little bit of what was left, but he found nothing. More than 95% of the paper was burned, and the remaining corners were meaningless blanks.

Tang Juyi stood in place for a moment, then walked quickly to the destroyed instrument, and sure enough, he saw a distorted flat structure, and a broken pen needle on it, probably used to record data on paper.

Looking at all this, Tang Juyi gradually had an idea:

"They initially installed the instrument and then got some unusual data or records...... In the course of camping and exploring, their mental state was gradually affected, or perhaps something terrible reflected in the data records that caused them to burn all the documents and violently destroy the instrument......"

Judging from the appearance of this instrument, there is no hope of repair, so Tang Juyi can't understand what kind of data those people have detected.

Looking away, the only thing left of the place was a raised stone pillar, about the height of a person's chest, like a naturally occurring rock.

The top of the rock had been cut and what should have been irregular edges and corners, but now it was a smooth plane, and a recessed groove remained.

Looking at the triangular groove, Tang Juyi could know what was originally placed here with his toes:

"Gold-veined slate...... They took the gold-veined slab from the pillar. ”

There was no text left by ancient civilization on the stone pillar, and even if there were, Tang Juyi couldn't understand it, so he didn't pay attention to the stone pillar anymore, but looked farther away.

"Is that what they call the abyss?"

About 30 meters from this improvised camp, there is a bottomless fissure...... No, it's not so much a fissure as a cliff, because you can't see the other side at all, or even if there is one.

Tang Juyi turned on the light he was carrying and shone it on the other side of the cliff, and then he barely saw the appearance of the other side.

Rough estimates put the span between these two sides at least two hundred meters.

Tang Juyi slowly walked to the edge of this cliff, looked down, but what he saw was bottomless darkness, and the fluorescent minerals on the cliff wall extended all the way to the end, forming a light band like a vertical bridge, which looked beautiful, like a scene in a dream.

However, even then, only the glimmering bridge could be seen extending into the distance, which was invisible to the naked eye, and then it was no longer visible, and the bottom was obviously extremely deep.

Tang Juyi thought for a moment, took out a short-term lighting stick from his bag, and then threw it towards the bottom of the cliff. The light stick lasted for a short time, but the light was just as dazzling, and the purple-red fire almost illuminated the area tens of meters around Tang Juyi.

One second.

Two seconds.

……

Minutes passed, and no sound was heard, as if the rod had disappeared forever into the abyss beneath the cliff.

"Either the bottom is much deeper than you think, or there's some kind of cushioning at the bottom that prevents echoes from coming in, like vines or currents. But the light of the light stick was no longer visible...... I think it's too scary. ”

Staring at the pitch-black abyss, Tang Juyi always felt that it was not a good place below, although his eyes could not reach it, but the unsettling feeling that vaguely emanated from it was very strong.

Shaking his head, Tang Juyi retreated again, no longer stopping on the edge of this dangerous cliff.

Due to the log found in the submarine before, Tang Juyi deliberately prepared ropes and nail hooks for climbing before this trip according to the description, but they were not needed at this time, because the height of this cliff had greatly exceeded the length of the rope prepared by Tang Juyi.

In this way, Tang Juyi could only dispel the idea of going down to explore, and instead hit the idea to the other side.

Through the searchlight in his hand, Tang Juyi did see the "other side" recorded in the log, but it was only a vague outline, and he didn't know anything about what kind of thing was on it.

"Until now, there has been no trace of Jiang Shuiyue."

Tang Juyi returned to the camp and fell into thought.

Jiang Shuiyue should have followed them to this underground cave, but she didn't leave any traces...... They didn't encounter the tentacles at the bottom of the deep pool, nor were they harmed by the stone carving, so theoretically there shouldn't be any other danger factors. ”

Turning his head to look at the edge of the cliff, Tang Juyi slowly narrowed his eyes, as if he had a guess.

"The fact that the people in the expedition team thought that Jiang Shuiyue was dead, but there was no body left here only shows one thing - she was in some kind of situation where it was impossible to survive...... At least not to others, it was impossible to survive, and the body could not be found. ”

"In other words, it is very likely that she fell under this cliff in front of those people......"

This speculation is based on the information obtained so far, because Tang Juyi came from the stone gate and knew that although the passages here occasionally forked in the road, they all converged on the same place, which was this cave. There was no corpse of Jiang Shuiyue during the period, so there can only be one or two possibilities:

1. Jiang Shuiyue lied, she didn't participate in the trip at all.

2. The members of the four expedition teams teamed up to kill her, and buried her body by the way

3. She fell off a cliff in front of four other people.

Judging from the note Jiang Shuiyue left for Tang Juyi, she must have come here to explore the truth under the sea, and the time of her disappearance can also be matched with it. If she is still hiding in Haichao City, according to the Phil family's news network, it is impossible not to find her whereabouts.

As for the second ...... Tang Juyi didn't think that these people had the ability to kill Jiang Shuiyue, because that woman's vigilance and observation were strong enough.

Tang Juyi walked to the edge of the cliff again, looked down, and felt a little entangled in his heart:

"So...... Should I say youjump, ijump? ”
