"The rock wall is empty, there must be a mechanism here, let's all spread out and look for it." Alan Lin knocked on the rock wall and said.

After all, I have read the "Tiangong Secret Spectrum" given to me by my grandfather, so I still know a little about the mechanism, but the problem is that most of the techniques mentioned in the "Tiangong Secret Book" are used in the Central Plains, and the Heizhugou where we are located belongs to the ancient Dian cultural area in ancient times, so I don't know if it is applicable.

"Chengzi, there's a discovery!" While I was thinking, Zheng Tian suddenly pointed to an area covered with weeds on the rock wall and said excitedly.

Hearing this, Elan Lin and I walked over and quickly pulled out the weeds, and found that there was a turntable on the stone wall, and the word "ink" was engraved on the turntable, and the circle of the turntable was from zero to twelve, and the thirteen numbers in capital letters were similar to a wall clock.

"This ...... Isn't this turntable the one in the secret passage of Zanglong Mountain? Do you remember Zheng Tian, the one who put the treasures of the Taiping Heavenly Kingdom. I looked at the familiar guy in front of me and was amazed.

"Damn, of course I remember, seeing this thing reminds me of the gold and silver treasures that I almost got my hands on, and I still hate it."

"You've seen this mechanism?" Seeing that we were reacting violently, Elanlyn asked.

I nodded, but I didn't feel good to tell her about the ancient tomb of Zanglong Mountain, so I made up one casually: "I encountered it when I followed the archaeological team to archaeology before." ”

This kind of mechanism is related to the Mo sect, it seems that the people in this Mo sect have also patronized the black bamboo ditch in the southwest mountainous area, is there any connection between this place and the ancient tomb of Zanglong Mountain? Thinking of this, the desire to open the secret door to find out is getting stronger and stronger.

So I said to Zheng Tian again: "The four numbers that unlocked the mechanism last time were 9, 7, 0, and 0, should we still use this?" ”

Zheng Tian was a little worried: "But when I tried to open the door of the treasure room for the second time, these four numbers didn't work. ”

"How do you know if you don't try?" As I spoke, I turned the dial according to these four numbers.

Nine-seven-zero-zero

"Boom—" A large stone door slowly rose next to the turntable.

It seems that these are really the four numbers.

"Mozong's gang is so lazy that they don't even change their passwords." Zheng Tian looked at the open stone door and complained casually.

"You think that the people of the Mozong are all the same as you? In my opinion, this 9700 must have some special meaning. I choked him, and when I saw that Alan Lin had walked into the stone door without saying a word, I followed suit.

When we came to the other side of the stone gate, we were presented with an unusually empty cave. This kind of spaciousness can be said to completely intimidate all three of us. I've visited famous caves like Yinziyan in Guilin before, and at the time I thought the stalactites inside were spectacular, but now they seem to be nothing more than a small one.

We sent the only flashlight around, and some of the stalactites here looked like the needle of the sea god falling from the top and hanging down to the bottom, some were like rolling waves, covering the rock wall, and there were even many like jellyfish and sea fish, all lying quietly on the wall, living out of an underwater world.

"This place is awesome, if it is developed by the local government, then the tourism income will not rise!" Zheng Tian was stunned and said.

"If we really develop it for the local government, this place will probably be destroyed." I shook my head and said.

Then I looked around carefully, we were about halfway up the mountain, looking down at the bottomless, looking up at the sky, all thanks to a plank road attached to the rock wall, people can barely move forward.

"This plank road must have been here for hundreds of years, can you still leave?" Zheng Tian said worriedly.

I looked at the incomplete plank road, and I couldn't be sure, if I stepped on the air, the consequences were unimaginable. But at the moment there is no other way to go but this one.

"Don't hesitate, the target is in this cave, we're going to give it a try anyway." After Ailanlin finished speaking, she stepped on the plank road one step ahead of us, and the plank road shook violently at the moment.

Zheng Tian and I glanced at each other, and then stepped onto the rickety plank road.

Walking up the boardwalk, you can experience what a real heartbeat feels like, unlike the heartbeat of a roller coaster in a playground and playing a pirate ship, it can touch death.

We almost always moved forward a little bit by holding on to the rock wall, and we were careful with each step, for fear of bumping the fragile plank road under our feet. Halfway down the boardwalk, Elan Lin suddenly motioned for us to stop, made a gesture not to speak to us, and then leaned into the rock wall and said, "There seems to be some strange sound." ”

I was already very nervous, but now that there was a sound, I felt even more empty, worried that a group of bat-like strange creatures would suddenly fly out of the ancient tomb of Zanglong Mountain to cause chaos for us.

But if you listen carefully, the sound is not so much like the cry of some creature, but like the sound of many people walking, this sound is small at first, but gradually it reverberates in this huge confined space, forming a huge marching sound.

This makes us even more puzzling, it stands to reason that there is an abyss next to us, and the only thing that can pass people is the swaying plank road under our feet, where does the sound of the footsteps of the march come from?

Just as I was thinking, Zheng Tian suddenly pointed to the panic in the abyss and said, "How can there be light there?" ”

Alan Lin and I immediately looked in the direction of his finger, and saw a small point of light dangling in the dark abyss, and as the footsteps became louder, the light point became more and more dense, and after half a minute, we saw hundreds of swaying points of light in the black area, constantly moving forward.

"I heard Uncle Dao say before that in some giant caves in the southwest region, there is a kind of flying fireworm, I don't know if we ran into it today." I muttered.

"Those flying fireflies bite people, don't they? How does it compare to a ghost sting? Zheng Tian was even more frightened by what I said.

"If they touch you a little, they will probably spontaneously combust all over their bodies, which is much more powerful than ghost stings." I replied in a suppressed voice.

Zheng Tian swallowed his saliva after hearing this: "Then what are we still doing in a daze, run away!" ”

At this time, Elanlin suddenly said, "No, those are not flying insects, they are torches. ”

"Are you kidding me? Will the torch grow wings on its own? Zheng Tian shook his head and denied.

Ai Lanlin replied calmly: "It's not that you fly, but someone holds it." ”

"You mean, all those dense fires are full of people?" I was incredible.

"Yes, it's people walking in the abyss with torches, that's why we hear footsteps." Alan Lin said with a grim gaze.

"! How is it possible for a person to walk in the air? Zheng Tian didn't believe what Ai Lanlin said at all.

"They're going to pass through us soon, and you'll see for yourself then." Elanlyn said firmly.

So we clinged to the wall and stared at the firelight that was approaching us, and sure enough, as Alan Lin said, when the firelight moved in front of us, we really saw the strange flickering torches, flickering and faintly hiding the miserable white faces.

The men were cloaked, cloaked, and carrying a rifle on their shoulders, and looked like they were supposed to be soldiers. They walked in front of us one after the other in a marching order. To our surprise, none of them turned their heads to look at us as if we didn't exist at all.

"This ...... What the hell is this! Zheng Tian looked at the soldiers who were walking in the air in front of him and said in a trembling voice.

At this moment, Alan Lin suddenly made a bold move, she took out a stone-like thing from the pocket of her clothes, and struck it at the body of one of the marchers with a "whoosh", and to our surprise, the stone passed through as if nothing had touched it.

"Damn! Won't they all be ghosts, could it be that we ran into the legendary Yin soldier crossing the border today? Zheng Tian said dumbfounded.

Uncle Dao taught me early on not to find ghosts to take the blame whenever something happens, after all, the road is so expensive, and ghosts don't want to come to the world. So I thought about it rationally for a while, and felt that the scene in front of me was very similar to what we saw in the ancient tomb of Zanglong Mountain, which may be some kind of magnetic field photography mechanism, which recorded a certain momentary picture of history, and re-presented it in the form of video at a moment of fate in the future.

I said what I thought, and several people discussed it again, but there was still no substantive conclusion, Zheng Tian saw that those soldiers couldn't hurt us anyway, so he shook the flashlight there, wanting to take a closer look at who these people were. Just as the flashlight hit one of the men's chests, Zheng Tian almost screamed.

"Chengzi, look at what the troop number is written on his clothes."

When I looked at it, I couldn't help but be dumbfounded: it said the new 51st Division.

This is Wei Hengfu's troops, we fought in the ancient tomb of Zanglong Mountain, but by then they had become bloody.
