"What! Where do you say? Is this possible? So obvious? Or in the middle of the city? I wonder if ~ that entrance will be in a hidden location! I said in amazement as I looked at the building in the middle of the city.

Nie Xiaoqian actually said that the secret entrance to the underground would be in such an obvious location? Or is it the middle of the city? How is this possible! If it were me, I'd rather build the entrance to a secret place, or just inside the mouth of that well!

Repair to the middle of the city? Isn't that too ostentatious? Is it known at a glance?

However, Nie Xiaoqian did not agree with my statement, according to what she meant. The scale of this underground stronghold is quite large, and there are so many people in it, it would be easier to expose it if the entrance was really built in the 'hidden' locations I mentioned.

Because there are so many people in it, there will definitely be traces of looking in and out. If it's a hidden place, wouldn't it be easier to be exposed. And put it in the middle of the city, so that all the patrolmen in the whole city can take care of the safety in the middle. Even if this place is overrun, as long as the newcomers don't know the secrets of the underground, they will definitely not think that there is an underground entrance in the middle!

Anyway, after telling me a lot of truths, they all said that the entrance must be in the middle. I thought about it, anyway, Nie Xiaoqian is an expert in this area! After all, isn't Lubanmen specialized in these? (Actually, this is my misunderstanding!) So she should be right. And if the entrance isn't there, it's actually harder to find anywhere else. If so, we might as well retreat directly!

Although I don't really understand Nie Xiaoqian's thoughts, this guy must know more about this kind of secret door or something than I do, so I decided to leave the whole process to Nie Xiaoqian to judge and lead the way. And I~ as long as I see the 'valuable goods', just take it away!

This is the 'male and female matching, not working'~ ahhhh Wrong! It should be 'division of labor and cooperation'!

However, after Nie Xiaoqian carried me around the city, I even began to wonder if this guy had ever been to this city, and even this city was built by their Luban Gate! After wandering around the ground for a long time, each time we entered a house that was open to the face of a small adobe house, and bypassed the guards in the house, we would find a large amount of goods or gold, silver, jewelry, and other goods. And then I put it all away without even thinking about it. I didn't expect there to be so much property in this little ruined city! It's a market dedicated to trading! And I also looted a large number of goods that Persian merchants often brought with me, and it seems that more than half of the people in this city were Persian merchants! Do they use this as a transit point?

As I pondered the origins of these merchants, I mercilessly looted all the treasures I could see. We kept looting half of the city's adobe houses. It was only because some merchants who got up in the middle of the night to inspect the 'treasures' and found that the goods had disappeared issued a warning sound, and then caused chaos in the whole city, Nie Xiaoqian carried me before anyone found it, and we touched the front of the two-story building in the middle of the city.

"Look! I'll just say there's something wrong here! So many guards are coming! The entrance to the secret passage must be right there! Nie Xiaoqian and I were lying on the roof, looking at the crowd below, and said to me.

But what's the use of this girl talking about it now! This place is heavily guarded, and even if we knew that there was an entrance, we wouldn't be able to break through the siege and rush in...... Even if it's rushing in! The enemy only needs to put one on both ends of the passage inside, and we will be finished!

But this doesn't seem to stop Nie Xiaoqian, she threw me on the roof and asked me to wait quietly, after this guy asked me for a shovel, she just left me and slipped off the roof!

This guy is wearing a black jumpsuit, plus the reason why he is super good at covering his head and covering his face. As soon as she leaves the roof, I can't see this guy's figure! After letting me shrink on the roof and wait for half an hour, Nie Xiaoqian, this girl, slipped behind me quietly, and when she called me, she almost scared me to death!

"That's it! Come with me! After Nie Xiaoqian said this, she took me to fly down again, and then came to a position about thirty meters away from the middle building, and then she pointed to a very rare tree on the grassland in front of her, and then after putting me down, she shook it to the trunk, and the person disappeared magically!

"I'll go! What the heck? Is it magical? "I couldn't help but shout! Fortunately, there is a lot of noise in this city now, otherwise it will definitely attract the enemy with that sound just now!

At this time, Nie Xiaoqian's head suddenly came out of the trunk of the tree, and then asked me, "Hey! What are you shouting about? Come on in! ”

With that, her head was gone again! I looked over and realized that there was a half-human-high hole in the trunk of the tree, which I didn't notice because it was so dark. Nie Xiaoqian got into this hole from this hole!

After hesitating for a moment, I also lowered my head sideways and got in, and then climbed down the tree hole for three or four steps, and I came to a square hall underground, which was also a square space two meters high and two meters wide. And it's so dark that you can't see anything clearly.

In addition, after Nie Xiaoqian saw me get in, she stretched out her hand to the side, and then pulled a rope and pulled it down, I heard a 'click' sound, and the light leaking in from the tree hole where we originally got into was blocked, and now it has completely become out of reach.

"Hey! Illuminate it! Nie Xiaoqian's voice came from beside me.

I took out my phone that I habitually carry in my pocket, and then turned on the flashlight function. That's when you can see the space here.

It looks like this square hall was built a long time ago! It's just that I don't know why there is some newly dug up dirt on the ground, although there is not much.

It was only after the light was lit that I saw that there was a hole in the innermost part of the hall that looked like it had been dug up. It's not very big, enough for Nie Xiaoqian and me to bend down and get in.

While I was still observing my surroundings. Nie Xiaoqian lowered her head and got into it first, then turned back to me and said, "What are you still doing in a daze?" Come in and help light it up! ”

After I bent down with her and got in, I realized that the passage in the hole here was not just dug out, but it was blocked by some loess about ten centimeters wide. And the shovel that Nie Xiaoqian took away just now is now thrown in this passage.

Once inside, it was much wider than the entrance to the cave, enough for the two of us to walk side by side upright! And this channel is a downward continuation. In addition, the appearance of the passage looks very familiar. I suddenly realized why this Nie Xiaoqian knew about this passage!

"Huh! Xiaoqian! You~ This underground space won't be built by your Lubanmen people! And this passage ~ is the back door you left behind! I, Nie Xiaoqian, said. After all, seeing what it looks like here, plus what the underground space looked like yesterday. When I think of these things, it reminds me of what the people of the lower five gates of Lubanmen and the people of the Yin-Yang family school under Luoyang City said at that time! It's no different from there at all!

Sure enough, after Nie Xiaoqian heard me ask her, she admitted it without hesitation. She also told me that when she took me to the roof ambush, she was trying to confirm the location of this 'back door'. And she also read me a big mantra that I didn't understand at all~ It sounds a bit like the kind of slip that often appears in some 'tomb robbing'~ Ahh It's wrong, it should be called 'secret formula'!

I don't understand it, but it sounds amazing!

And Nie Xiaoqian also told me that basically, the underground buildings built in the last few hundred years are basically the handiwork of their Luban Gate, and they habitually leave a 'back door' in each built building! Although it is said that the 'back door' was left to find their lost 'inheritance'...... This is similar to the news I got at the lower five gates! And after all this time, I seriously suspect that what they call the 'Inheritance' is actually the prototype of the imprint on my chest, the antique locket. So when I thought of this, I decided even more that I would never reveal these secrets again when I returned home! The province has provoked an enemy who can't be provoked! After all, I also heard a lot of the secret history of the year from Zou Rushui of the Yin and Yang family! There are so many schools or sects that have lost the 'inheritance'! The 'Hundred Schools' of Jixia Academy back then! As soon as you hear it, you are the 'enemy' of hundreds of schools!

I'm off track again and I'm starting to think nonsense!

After my attention was brought back here, I let Nie Xiaoqian take me away for about ten minutes! We're in front of a device we've seen several times before! Isn't this the kind of rail car and 'Weiya' that Zou Rushui used to 'fly' at that time? Although the installation here looks dilapidated! But Nie Xiaoqian asked me to come last time, and after I lent her tools to build the fence wall between the 'warehouse' and the gate of the mall, I asked me to take out some lube and a few solid wood benches. Nie Xiaoqian, this guy let me see a wonderful and abnormal 'carpentry performance'! Doesn't this thing mean that she is the person who specializes in martial arts training in Luban and is responsible for the duties of the guard? Why are her hands so dexterous!

I was amazed to see all kinds of planers, chisels, saws, rulers, ink fountains and hand drills, as well as a sharp axe, in Nie Xiaoqian's hand, flying up and down. Then with the dancing of the tools, a few solid wood benches were transformed into a bunch of pulleys by Nie Xiaoqian's exquisite craftsmanship, and then she didn't use a single nail, so she installed these pulleys on the dilapidated slide car, and after replacing all the parts here, she picked up the only lubricant that made her feel regretful, and then shook her head and said while lubricating the new pulley: "Alas! What a pity! You don't have our special grease beeswax there, otherwise why use your lubricating oil! Although the lubricating properties of this grease are good, it is too corrosive! I knew it when I helped you remodel your 'car'. It is estimated that it will not take a few years to corrode this out! It's a pity! If you use our kind of grease beeswax, then this block can be used for hundreds of years! ”

"Hundreds of years?" Hearing Nie Xiaoqian's boasting, I suddenly realized a possibility~ According to what she meant, wouldn't it mean that this broken pulley was made a hundred years ago? That means ~ this underground building hidden in the depths of the grassland, and the 'Zoroastrianism', didn't it take root here a hundred years ago?

Suddenly I was moved by my own intelligence, and found that I was 'again' smarter, and my thinking was more sensitive and pioneering~ I was a little proud of myself, and then I told Nie Xiaoqian what I had just analyzed.

Then this guy pointed to the small word next to the pulley and said: "Oh~ You look! Isn't it written here? February of the second year of Wutai! In other words, this is until now~ I'll do the math! Oh! It's exactly one hundred ~ two years! Nie Xiaoqian said after breaking her fingers and counting.

I was speechless after hearing this, these Lubanmen people! Not only did he leave a secret door, but he also recorded the date! Could it be that this is also the tradition of his sect?

When I was secretly complaining, I saw Nie Xiaoqian pick up the chisel and put it under the line of small characters on the pulley, and after a few random strokes, I saw a neat block letter appear there! And it turned out to be the relief text of 'Yang carving'~ Are they really obsessive-compulsive? Just leave a date and even leave it with embossed text~ Isn't it too troublesome?

"Uh~ Okay! I'm convinced! ”

After getting this, I secretly asked Nie Xiaoqian to put away the tools and the replaced pulleys, and then let Nie Xiaoqian carry me again, and then she rolled the rope of 'Weiya' onto her own waist, and then I saw that this guy didn't know when he actually carved a wooden belt. It seems that the people of Lubanmen are already familiar with this kind of pulley and the use of Weiya!

"Alas! I don't know how many of these similar 'black technologies' will be there for the people of their Luban Sect! I now suspect that the 'public loser' is actually a traverser! Otherwise, the 'Jishita Academy' that cultivated these monsters is simply an alliance of large traversers! "I complained silently in my heart, especially after thinking of the antique locket that took me to Datang, maybe it was also the creation 'product' of 'Jixia Academy', I became even more curious about that 'Jixia Academy'! Maybe I will have a chance to discuss their deeds in the future!
