The pages of this old notebook have been yellowed a little, and it is clear that it is not a short time.

I thought this should be the kind of decent adventure diary, but Zhang Luo only read a few pages and found that the content in it was not quite right:

18：16

It's fun to dance with bunnies! After drinking Coke, he left. 16，17，190，222。

13:00

It's overcast, I'm so happy!

12：23

Turn it over!

"Is this thing crazy......

Flipping back a few pages casually, and finding that it was still similar and unclear, Zhang Luo sighed helplessly and put the notebook into his jacket pocket.

Although it seemed like psychopathic nonsense, he always felt that the content of the notes was a little subtle. Maybe it will come in handy somewhere.

Moreover, Zhang Luo felt that he had now roughly understood the reason why this person lost his life:

"It's so ......cold here," he grumbled, folding his arms.

It's a far cry from the heat of the Sahara Desert, where the temperature is unbearably low in underground caverns hundreds of meters above the ground. Just standing in place, I couldn't help but get goosebumps all over my body.

That's all it takes, the most tragic thing is that when I was too cold, I found that the other three "people" around me were monsters who didn't need to keep warm at all.

"Is it cold? I don't feel it. The half-demon stood there and took a deep breath. Hasiner, who was the god of death Anubis, also shook his head.

As for the machine girl next to her, it is completely impossible to have the feeling of "cold......

Despite this, Frankenstein took out a pitch-black round metal device and handed it to Zhang Luo, instructing, "Take it with you." ”

As soon as he took over the device, Zhang Luo suddenly felt a tingling pain in his palm, hurriedly threw the hot thing into his pocket, and then rubbed the hot red palm vigorously.

Although he didn't know what this hot thing was, after Zhang Luo brought this thing, he noticed that the temperature around him seemed to have increased a little, and he didn't have the feeling of shivering from the cold just now.

"OK, let's go." He said.

Leaving the body of the nameless explorer, the four of them continued to walk towards the deep interior of the cavern, the sound of footsteps breaking the dead silence in the cavern, and with each step, a long echo kept echoing.

The white light from the tactical flashlight on their wrists tore through the deep darkness, and for safety reasons, they were not moving very fast.

After about 100 meters, there was still endless darkness ahead, and the road leading to the interior did not bend, still maintaining a "standard straight line" drawn with a ruler.

"I think there's something wrong with this place......" The half-demon whispered.

"Nonsense." Zhang Luo responded simply and rudely.

Venturing into this strange lower city with extremely low visibility, even a "madman" like him has become much more serious at this time.

Adventure is not the same as death, and venturing in an almost completely unknown territory requires extreme care.

"Smack!"

With a soft sound, the four people stopped at the same time, and at the same time as they pulled out their weapons, the pillars of light of the four flashlights instantly focused on the location where the sound came from.

"Smack!"

Droplets of water that shimmered in the light fell freely and smashed onto the stony ground.

Realizing that it was just the sound of water droplets dripping, Zhang Luo did not take it lightly, but moved the aperture projected by the flashlight to the position directly above the water droplets.

"It's ......"

When they saw the scene at the top of the cave, the movements of the four stopped again.

The top of the cave was nearly ten meters above the ground, and they had observed it when they were advancing just now, and there was nothing unusual on it.

However, it is not quite the same here......

- If there is anything more terrifying than the sight of a corpse on the ground, it is the sight of a corpse hanging from the ceiling.

What's even more terrifying is that there is more than one corpse on the roof of the cave.

Four rotting human corpses, as if embedded in the rock at the top of the cave, hung quietly, their hands and legs hanging weakly, and from time to time "water droplets" fell on their bodies, smashing on the ground with a crisp sound.

All four bodies were male, and they looked like they had been dead for some time, but they were certainly better than the "Indiana" at the entrance to the cave. Jones "died much later.

And when he saw the tattered gray clothes on the four people, Zhang Luo immediately recognized the origin of these guys:

"The expedition that disappeared in the Sahara Desert three months ago?"

He is very sensitive to such incidents, and remembers the news that he saw three months ago about the mysterious disappearance of a four-man expedition in the Sahara Desert:

It was four young men from Northern Europe who, in order to celebrate their coming of age, were well prepared and tried to cross the Sahara Desert.

At first, their journey was very smooth, and they didn't forget to take some videos every day and post them on their personal website, but one day when they arrived on the northern side of the Sahara Desert halfway through the journey, they suddenly disappeared from the world and lost all contact with the outside world.

At that time, there were also other explorers who were hiking in the vicinity, and after hearing the news, they searched and rescued the area. But no clues were found, and the young four-man expedition disappeared completely.

Now, they have finally reappeared...... It's a pity that it has long since become a rotting corpse.

Not to mention why this group of guys who are supposed to cross the desert appear hundreds of meters underground, Zhang Luo still has more important questions:

"How did they get there?"

The rock walls of this cave are like modern tunnels built by humans, and they are not only very smooth, but there are no grippers on them to climb. Even if his strength and agility are far beyond ordinary people, it is impossible for him to climb to the top.

"I don't know." Frankenstein's answer was succinct.

"It looks like he fell to his death." The half-demon made a joke.

Hearing the flat-headed man's words, Zhang Luo's brain was about to directly filter out this "useless information", but suddenly thought of something. Immediately took out the notebook he got from the entrance of the cave and flipped to the third page, and looked at the text on it by the light of the flashlight:

12：23

Turn it over!

"Could it be that these guys really fell to their deaths?"

Imagining the whole cave turned over, and the person who was originally standing on the "ground" fell towards the "ceiling" below, Zhang Luo suddenly had a hint of foreboding in his heart:

-- When my group came down, it was noon.

took out his mobile phone, which had long since run out of signal, and looked at the time, Zhang Luo realized that the time was now twelve o'clock. Other words......

"I think we'd better get out of this place ...... the hell."

Without time to explain, he immediately strode forward and ran wildly towards the darkness ahead.
