The biting chill made me shiver, and then I became more and more energetic.

In this environment, we must not have the mentality of slackness and slackness, and we must always maintain high spirits.

When our Red Army climbed snowy mountains and crossed grasslands, at least half of the soldiers who died died in this resting and exhaustion.

When fatigue reaches an extreme, rest becomes a luxury, and the psychology of "resting a little longer" is often the culprit who kills the most.

I sat down against Professor Chen, but my eyes were wide open, and I didn't say anything to Professor Chen, I just stared straight at the stone steps that snaked above our heads.

At this time, Professor Chen, who was sitting next to me, suddenly opened his mouth.

"Brother Wang, look"

When I heard the sound, I turned around and saw Professor Chen pinch up a small object from the stone steps not far away.

I looked closely, and saw that what Professor Chen was holding in his hand was a cigarette butt.

I couldn't help but raise my eyebrows, took off my gloves and reached out to pinch the cigarette butt handed over by Professor Chen, and took a closer look at it with the afterglow of the flashlight, and there were still a few English letters left at the end of the cigarette butt.

However, when I pinched the cigarette butt in my fingers, I frowned again.

Those "French foreign mercenaries" came in more than ten or twenty years ago, and if this cigarette butt was really brought in by them back then, so many years have passed, and in such an environment, this cigarette should have been as hard as a hard stick.

But the cigarette butt I was holding in my hand was not only not dry and hard, but soft.

Moreover, the cigarette butt is pinched between the fingers, and it seems that there is residual warmth, as if someone has just finished smoking and dropped it here.

With the cigarette butt in my hand, I couldn't help but look up at the dark stone steps above me.

The cigarette butt that Professor Chen found clearly tells us that the person who fired the flare before had also ascended the stone steps to the top of the high wall, just like us, and that this cigarette butt should have been discarded here by this person.

At the same time, the discovery of this cigarette butt made me even more suspicious of the judgment that it was my own person who fired the flare.

Because, in my impression, Bai Yi and that Jasmine are non-smokers.

"Professor Chen, we have to be careful."

I looked up at the dark stone steps above me as I whispered to Professor Chen.

After the words fell, I casually threw away the cigarette butt I was holding in my hand, and stood up with a short knife.

"Hey"

From behind me, Professor Chen's soft sigh was heard.

What this cigarette butt tells us, Professor Chen is also very clear, and Professor Chen at this time also understands that after we go up to the high wall, the person we meet will not be his daughter Bai Yi to a large extent

As we climbed the stairs again, Professor Chan and I became more and more cautious.

After making sure that the person we met was probably not my own, my nerves instantly tightened more and more, not only did the speed of walking along the stone steps become slower, but also every time I walked up the stone steps, I would inexplicably feel an illusion from the bottom of my heart when facing the blind corner in the darkness that the flashlight could not illuminate.

It seemed that in the blind corner in the darkness, there was something at this time, staring at me and Professor Chen who were slowly moving towards the clouds.

The nervousness of Professor Chen and I has always been with us, and we don't know how long we walked slowly along the stone steps to the rock, and after walking through countless dark blind corners, I imagined that in the darkness, something bared its sharp teeth and opened its foul mouth to pounce on me.

Moreover, this winding and extremely insecure stone staircase has finally come to an end.

With the help of the bright flashlight held by Professor Chen, I saw that after walking a dozen or so stone steps above my head, there was a rectangular exit several meters long and wide.

This should be the exit to the top of the wall.

I asked Professor Chen to wait where he was, and then after receiving the flashlight from him, I walked up a few stone steps lightly.

There was no cover at this rectangular exit, and I walked a few stone steps up the stone to just in time to peer out from the exit.

When I held up my flashlight and shone out from the exit, I couldn't help but be stunned, and then gasped.

"Hiss"

"What's wrong?"

Professor Chen was not far away from me, and when he heard my gasp, Professor Chen hurriedly whispered to me.

Hearing Professor Chen's urgent question, I came back to my senses, and after holding up my flashlight and shining a picture around, I shook my head and replied to Professor Chen in a low voice.

"Nothing up?"

With that, I stepped out of the rectangular exit and literally stood on top of the high wall.

After hearing what I said, he saw that I was walking up, and Professor Chen quickly climbed the actual steps, walked out of the exit, and stood beside me.

On top of this high wall, Professor Chen and I are standing on the left side of the place is an unfathomably high rock wall, and from the range of flashlight, we can see that this rock wall is very smooth and smooth, and there are some strange shapes and incomprehensible patterns and words carved on it.

The patterns and characters are carved quite large, and a single odd text must be a meter or two in length and width.

After seeing these strange words and patterns, Professor Chen, who was beside me, suddenly emitted that kind of "gurgling" and speechless movement from his throat.

I know very well why Professor Chen would make such a sound at this time, and for an expert in the study of ancient characters, he will definitely be quite excited after seeing these huge and strange characters.

And, if I'm not mistaken, Professor Chen will certainly not see these strange words for the first time.

At that time, Professor Chen and his archaeological team members once saw tall and strange characters in the caves above the cliffs in the mountains.

The words must be the same as the ones we see on the cliff before our eyes.

Sure enough, I only listened to Professor Chen's throat "grunting" for a long time, and finally opened his mouth.

"O Lord! I didn't expect to see these words here again, but it's a pity that after so many years, I still haven't been able to crack the secret."

As he spoke, Professor Chen slowly walked to the side of the rock wall, stretched out his hand and gently stroked the text pattern engraved on the rock wall, revealing an indescribable sigh in his words
