This wall appears quite abruptly in our view.

When the wall shines on the flashlight, it emits a strange blue-purple color, which is simply incompatible with the color of the ice fields we are used to.

"Professor Chen, take a picture of it!"

At this time, Professor Chen and I had already walked to a distance of thirty or forty meters from the wall, and after staring at the bruised wall in front of me, I opened my mouth to Professor Chen.

As I said, Professor Chen held a flashlight and shone it along the blue-purple wall.

To my surprise, the wall was quite high, at least a few tens of meters high.

In the dark, under the illumination of a strong flashlight, seeing such a wall suddenly appear in front of my eyes, I really have a strange feeling that I can't explain.

Professor Chen held up his flashlight and shone it at the height of the wall, and before I could speak, he turned his hand and shone it along the blue and purple wall to the left and right.

The bright flashlight shone through, and the end of the two sides of the wall could not be seen at all.

Needless to say, this is the long platform at the end of the ice field we saw earlier, and it is also the same place where the flare was fired earlier.

This tall blue and purple wall feels like a city wall, but I have never seen a wall built so high.

From the angle where Professor Chen and I stood, we couldn't see if there were any other buildings built above the bruised wall.

If you go closer, you can't see any entrances or the like on top of this wall.

"Go that way."

With feeling, I pointed to the left side of the wall and whispered to Professor Chen.

It is said that it is based on feelings, but in fact, it is also a stroke of luck.

However, I was lucky enough to make a discovery after slowly walking along the left side of the wall for a distance of about 100 meters.

Above the wall, I found a rectangular doorway.

This doorway is nearly four meters high and about two and a half meters wide.

If it is placed on the ordinary city wall, it can be regarded as a small city gate, but on this blue and purple stone wall, the doorway hole of this size is really quite small.

When I found the doorway, of course, I wanted to go in and find out.

It's just that standing outside and looking at the inside of this doorway, it is pitch black, and through the strong flashlight of Professor Chen, you can see that there seem to be stone steps winding up the doorway.

It seems that if you enter this doorway, you can go up to the top of the wall by following the stone steps.

"Let's go in now, you should be careful."

I whispered to Professor Chen, who was following me, and after seeing the old man nodding at me with a serious face, I clenched the short knife in my hand and walked into the doorway.

Professor Chen followed me in, and the bright flashlight shook a few times on the stone steps under my feet, allowing me to see the stone steps that meander towards the stone steps more clearly.

I have to say that the stone steps on this direction are still very dangerous, and the stone steps are only about two meters wide, which cannot accommodate two people walking side by side.

Moreover, there is no guardrail on this stone step, so when you go up, you can only walk close to the side of the wall, and the more you go up, the more people will feel trembling on the side without the guardrail, especially for people like me who still have a fear of heights.

"You must be careful, please pay attention to your step"

My voice of Professor Chen's advice also began to tremble involuntarily, and Professor Chen did not answer, but just nodded to me, and the bright flashlight in his hand was always shining on the stone steps we walked towards the mountain.

At the same time, I was still nervously listening to any unusual movements around me.

Earlier, we saw flares that weren't meant to be carried by us, but they were fired from above the wall.

Moreover, the person who fired the flare should still be on top of the wall at this time, and if we touch it like this, we are likely to encounter this person.

Although it is not known whether the person who fired the flare is friend or foe, it is better to be cautious in this environment.

I walked up the stone steps, but I didn't hear anything unusual on the way, except for the sound of my feet as Professor Chan and I approached each other.

I was exploring the road in front, Professor Chen was holding a flashlight in the back, and the two of them didn't know how many stone steps they had climbed up to the road, and they didn't know if the road was about to reach the top of the wall.

Although, I'm not as gasping as hard as Professor Chen. My physical strength has dropped so much, but after such a long period of rapid marching and a long time of rice water without teeth, my physical strength cannot be replenished, and my feet are inevitably a little weak.

At this time, I sincerely admired Professor Chen, as an old man of this age, who also did not have any physical supplements, he actually followed me to this place, completely relying on his own perseverance to persist.

At this time, looking at Professor Chen in front of me, I could completely imagine being in that mountain tomb. How did Captain Chen Jinting and Captain Chen of this archaeological team take their team members to life and death.

It's just that the years are unforgiving, and Professor Chen at this time is already in his sixtieth year, and he has long lost the life-and-death style he had with the Japanese female spy.

"Professor Chen, let's rest."

Looking at the stone steps above, I don't know how many roads there are to reach the top of the wall, and Professor Chen behind me is panting like a cow, I simply thought about stopping first and talking slowly, and by the way, I wondered what to do if I saw someone I didn't know after going up.

I said stop and rest, but Professor Chen didn't say anything, and sat down against the wall on the side of the stone steps.

Professor Chen has been talking noticeably less since he entered the doorway, and I can tell that he seems to be more nervous at this time.

Professor Chen is also beating a drum in his heart, and it is uncertain whether he is friend or foe.

Moreover, it is more likely that they will be enemies here.

If it is really an enemy, if we go up now, it will definitely be a fierce battle when we meet, and it is inevitable that Professor Chen will be so nervous.

I sat down next to Professor Chen against the wall on the side of the stone steps.

In this frozen world, although the physical strength of a long march will be very exertional, it can also produce enough temperature on people's bodies to resist the low temperature of dozens of degrees below zero.

At this time, after Professor Chen and I stopped, we could suddenly feel a chill on our bodies penetrating through the thick mountaineering suits0
