The traces of the artificial excavation of this ventilation channel are obvious, it should be dug out by the Tibetan people when they built the tomb for the princess of Jincheng, I don't know how long, the whole is straight down.

Why do you say it's easy to dig?

Because the craftsmanship is so bad!

I have not done less things to drill ventilation ducts, all kinds of ventilation ducts have not been less knowledgeable, this kind of structure is actually not much in our country, as far as the ventilation ducts I have seen so far are concerned, the most representative and highest achievements should be the Canberra pyramid seen in the ruins of Atlantis civilization, the splicing technology of the pyramid is quite powerful, the ventilation duct is very hidden, if it is not for the fat man with a pipe and spoon, can we find it or two, and the splicing process and materials are also very particular, The stone slabs used to lay the ventilation ducts are polished very smooth, like freshly waxed floors.

And the ventilation duct in this ancient tomb of Princess Jincheng obviously does not have such a high level of craftsmanship, it is a dirt road, if it were not for the higher terrain of Qilian Mountain, the thick soil layer, and the more stable crust, I am afraid that this ventilation duct would have collapsed long ago.

As for why an ancient tomb with a "death door" structure would have a ventilation passage in the main burial chamber, this is not something I can figure out for the time being! The "Death Gate" structure means that the owner of the tomb must be completely isolated from the world, and suddenly a ventilation channel leading to the outside world is a bit unreasonable. However, the secret of Princess Jincheng is big, this person has mastered the principle of "Tui Bei Tu" without accident, and can already be regarded as a person in our industry, but there is no Taoism, and it is normal for her tomb to be a little weird.

I didn't have the heart to think about it, my legs stuck on the left and right sides of the ventilation duct, and I carefully slid down the rough dirt tunnel little by little.

The ventilation duct is cold, to be honest, carrying a dead man with a corpse on his back to drill such a ventilation tunnel alone, I am still quite worried in my heart, Princess Jincheng's cold arms and thighs are tightly wrapped around me, when I move downward, from time to time will touch me, every contact, her cold skin will give me the same feeling of electric shock, several times I have the illusion that she is moving, the whole person is in a state of "fried hair", the taste is definitely not wonderful.

I always felt that behind the princess's sweet smile on my shoulder, as if she were asleep, there was a pair of eyes staring at me deeply, all the time, never leaving, as if they were staring at me......

It was in this situation that I groped my way down the ventilation duct with trepidation.

Several of our flashlights have been blown off, and the spare ones are basically lost during the horse war, and the fire breaker can't be used in this place, so we can't keep it in our hands, right? No matter how thick the skin is, I can't bear to roast it so much, and it doesn't take long for me to turn into roast pig's trotters! So, I always acted in the dark, and I don't know exactly how long I walked down, but the further down I went, the more viscous the air in this ventilation tunnel seemed to be getting thicker and thicker.

No, to be exact, it should be...... The air became moist.

The further down I went, I could feel the place I was holding on, stepping on, starting to get sticky, and it was the moisture that thinned the dirt in the ventilation tunnel.

Moreover, the surrounding environment seems to be getting warmer and warmer.

When a stream of water vapor came up from the dark ventilation duct, I felt a warmth that I hadn't felt for a long time, as if I hadn't felt it since I entered the Nalengrad Gorge, and I couldn't help frowning for a moment.

It seems that this ventilation tunnel is really built very deep, and the closer it is to the center of the earth, the hotter it gets, because the center of the earth is constantly dissipating heat, but unfortunately this heat cannot be conducted to the ground, that's all.

And, not surprisingly, below us, there should be an underground lake!

Just when I was full of doubts, secretly guessing what kind of world is underground, without warning, I felt that my right foot slipped and stepped on the air when moving down, and I lost my balance at that time, so I didn't fall down directly, but fortunately, my reaction speed was still relatively fast, and my two arms hurriedly exerted force, and both hands grabbed the more convex places on both sides of the ventilation duct in time, which stabilized my body.

I don't know if it's my delusion, but at the moment when my right foot stepped into the air and my body lost balance, I obviously felt that the princess of Jincheng on my back was hugging tightly!

That's right, she's absolutely moving!

This scared me a lot, and after stabilizing my body, I was motionless for a long time, and I finally breathed a sigh of relief when I found that she had no next move.

Stepping into the air when your right foot moves down means that I have reached the end of this ventilation channel.

What's next?

I couldn't see clearly, so I looked up and yelled, "Who's following me?" ”

"It's me!"

Zhang Jinya's voice came from the ventilation duct, and it seems that after I came down, it should be Zhang Jinya who followed me!

"I'm at the end of it!"

I looked up and said, "You throw a fire fold down, I'll see what's going on below!" ”

"Okay, wait a minute!"

Zhang Jinya's voice came from above, and listening to the strength of the voice, I could probably tell that he should be about a hundred meters away from me.

I waited patiently, and after about ten seconds, there was a "snort" sound in my head, and a little fire suddenly lit up, and then fell directly towards me!

Lao Zhang's goods......

What do you usually do, but now it's very good to throw a fire fold, and the meow is very accurate, just above my head!!

You won't wipe the wall of the ventilation duct and throw it? Just throw it down!

I was startled, my legs propped up on the right wall of the ventilation duct, my feet stuck in the bulge of the earth wall, to prevent myself from falling, and my body quickly retreated to the left to avoid the falling fire.

In this way, I was closer to the princess Jincheng on my back, and I could even clearly feel every curve of the other party's bumpy body.

However, I swear, I don't have the slightest feeling of being scared!

All kinds of signs show that this princess is absolutely sober, I am afraid that I am not enough, and I dare to YY?

Hula!

By this time, the fire fold had already fallen, and although I tried to dodge it, it still wiped my face, and I could smell the stench of my hair being burned, and then the fire fold "snapped" on my leg, and then it fell down the corridor.

I didn't care about being frightened, and hurriedly looked down, and by the bright light from the fire fold falling all the way down, I vaguely saw that under this ventilation channel, there seemed to be an underground lake?

The surface of the underground lake was not far from the exit of this vent, and it was only thirty or forty meters high at most, and the fire fold fell into the lake almost in the blink of an eye, and then it was extinguished at once!

If you have an underground lake, you can jump!

As soon as I gritted my teeth, I was about to drag Princess Jincheng to jump down directly, but before I could move, a particularly majestic male voice came from under the ventilation duct.

"Look, Firelight!!"

The male voice said in a hurry: "Go over and look, it seems that there is a black hole over there, and there are people in it!" ”

As soon as the male voice ended, the bright light from several flashlights shone towards me.

"Let's go, let's take a look!"

A female voice sounded: "It is very likely that they can appear here at this point in time, it is very likely that they are Xiaotian!" ”

I was stunned.

The male voice that spoke at the beginning was Xuanchen's, and the female voice after that was Yi Shiting's!!

How did they end up near the underground lake?

We were scattered in the frozen canyon, and then there was an avalanche and a heavy snow closed the cave, and they definitely couldn't enter the frozen canyon!

Don't...... Is there any other place to get into this underground space below me?

Anyway, no matter what, I'm pretty sure the people below are Xuanchen and the others, although I don't know how they got in, but it's a good thing to be able to meet them, isn't it?

With my teammates below, I was completely down-to-earth, tightened the thick bandages that tied me and Princess Jincheng, and then jumped directly towards the underground lake below!
