The place where we landed was also a cave, but there was no such precaution as if it were a great enemy, so a table was set up at the exit, and two people were seated, wearing old-fashioned armor and a knife pinned to their waists, like guards. Behind them was an ordinary door.

Zhao Laodao was not surprised, and took the lead in walking over, and I hurriedly followed.

"Lu Yin!" One of the guards asked, holding out his hand.

Zhao Laodao took out the envelope given by Lao Xin just now and handed it over. The guard examined the documents inside and nodded to his companion to indicate that there was no problem. The other stood up and walked to Zhao Laodao's side.

Zhao Laodao took out all the things on his body and put them on the table for him to check. After inspecting the items, the guard also searched Zhao Laodao's body to prevent him from carrying private goods.

"So strict? It's all in time for a flight! I couldn't help but curse.

But complaining is complaining, the first time I came to such a strange place, I didn't dare to make a mistake, or honestly learn from Zhao Laodao's practice and cooperate with the guards' inspection.

Actually, I'm quite worried that Zhao Laodao won't be able to pass the security check, because he actually has a sword in his belongings!

"Boom!"

The security guard pulled the sword out of its sheath, it was shining with cold light, extremely sharp, and it was still a real sword!

But the guard also looked at it, put the sword back again, and returned it to Zhao Laodao.

"You can bring in such a controlled knife? So what's the point of this kind of security check? "I was just confused.

I didn't have anything to check, but that pair of ruyi chopsticks caught the guard's attention and took a second look.

"It's okay, let's go in!" The guard beckoned behind him and said to us.

We put our belongings back away, pushed open the door and walked out. Sure enough, there is no hole outside!

A huge cavern is dotted with buildings, houses, squares, and warehouses. In the middle of the side of the cave wall, stands a three-story white building, there are guards in front of the building, and there is a small garden behind the building, planted with all kinds of exotic flowers and plants, elegant and chic, which is particularly distinctive.

"That's the City Lord's Mansion." Zhao Laodao saw that my eyes were staring at the small building for a long time, so he said to me.

"Who the hell is this city lord? Can such a Yin City be built here? I asked him with interest.

"The city lord has the surname Zuoqiu, and his full name is Zuoqiu Maoming. He was once one of the commanders of the underworld, and was later dismissed due to the failure of the encirclement and suppression of the ghost army. But I heard that this matter is not as simple as it seems, and it also involves the power struggle between the middle and high-level of the underworld, and the city lord of Zuoqiu is just a backbiter. ”

So, the city lord of Zuoqiu left the underworld with some of his old subordinates and began to establish the Yin City here. Some other exiled cultivators who were also dissatisfied with the prefecture also came to join him, and the city gradually grew. Therefore, this city is also called Zuoqiu City! ”

Zhao Laodao also had a look of reverence when he talked about this Zuoqiu City Lord. The big guy who dared to fight against the underworld and built a yin city independently, is naturally a legend, how can he not be admired?

"But why can the underworld still tolerate the existence of Zuoqiu City?" I asked again, "Could it be that Zuoqiu City is already strong enough to compete with the underworld?" ”

"Not really. From the very beginning, the Difu tried its best to erase the influence of Zuoqiu City, and sent troops to encircle and suppress it many times. Zhao Laodao explained, "But Zuoqiu City is located at the intersection of several major Yin veins, and it was originally a place where ghosts gathered, which was easy to defend and difficult to attack. ”

"Besides, even if the Yin City is captured, everyone can finally escape through the Yin Veins and break into pieces. As soon as the Yin soldiers of the underworld left, the city lord of Zuoqiu came back with everyone to rebuild. Therefore, in desperation, the prefecture can only take the way of Zhao'an to solve the problem. Now, Zuoqiu City only needs to nominally submit to the underworld and pay a part of the Yin Yuan every year. ”

"Isn't that the same elsewhere?" I asked with a smile. Originally, the status of the underworld in my mind was very mysterious and powerful, but I didn't expect that I couldn't even control such a dungeon.

"That's right!" Zhao Laodao nodded and said, "There are several similar Yin Cities underground, they are all inspired by Zuoqiu City, and they have started a guerrilla war with the underworld, forcing the underworld to acquiesce in their existence, or turn a blind eye, and they don't know it!" ”

"I didn't expect the underworld to have fallen to this point!"

"Nope! It's not that the underworld is in decline, it's that the underworld is too big to manage! Zhao Laodao denied my idea, "The underworld is still the overlord of the entire underground world, and no one can shake its status!" ”

I flattened my mouth, indicating that I didn't agree. After all, before I came, I always thought that Yin City was a very large place, but now it seems that the entire Yin City is only this size, and the number of people that can accommodate it is at most one or two thousand. If the prefecture can't even take such a small city, its own strength is estimated to be not much stronger.

Zhao Laodao also seemed to see my doubts, so he smiled and said, "Do you think Zuoqiu City is much smaller than you expected?" ”

"Yes, it's just a little bigger than the Xiling Ghost Market!" I do think so, "A dungeon of this scale can resist the underworld, and the strength of the underworld is too weak, right?" ”

"You still underestimate the underworld, and you also underestimate Zuoqiu City. It's just the upper city, and there's the lower city! ”

"Downtown?"

"Well, Zuoqiu City is divided into two cities." Zhao Laodao pointed to the distance and said, "Look over there, there is also a gate there, called the door, which is the only passage connecting the upper and lower cities." ”

I followed Zhao Laodao's hand and looked from afar, and sure enough, there was a door on the other side of the cave wall directly opposite the City Lord's Mansion, and people came and went, which was much more lively than ours.

"The upper city is not big, mainly these places: the city lord's mansion, the Yin Affairs Division, the Ghost Affairs Division, the city guard, the gate checkpoint and the exit of the yang world." Zhao Laodao pointed behind us and said, "The place we came from is one of the exits of the Yang Realm, and there are two others. ”

"What do the Yin Division and the Ghost Division do?" The other organizations understood what they did when they heard the names, but these two names sounded fresh.

"The Yin Affairs Division is the place where we are in charge of these Yin cultivators, and is responsible for dealing with all kinds of contradictions and disputes, including collecting taxes from large and small shops, caravans, and expeditions in Zuoqiu City, and so on.

"Then the ghost secretary is the yamen who manages ghosts?"

"That's right! There are more ghosts than people in the Yin City, and the Ghost Affairs Division is much busier than the Yin Affairs Division! ”

"That city guard is relative to the army in the Yin City?"

"It's pretty much the same, but it's still a police officer internally."

Zhao Laodao introduced me to me and took me to the door. The entrance door is composed of two tall stone doors, and behind the doors there is a winch, which requires the joint efforts of several big men to turn. Two rows of long tables were lined up in front of the door, where two caravans were unloading and inspecting, while officials counted the goods and calculated the taxes.

Zhao Laodao and I walked to the door and were also stopped, it seems that we have to pass not only when we enter the door, but also when we go out. But this time we came to buy ingredients, and we didn't carry any goods except Yin Yuan and some weapons and props for self-defense. A door-to-door official briefly inspected it and let us go.

But as soon as this came out, a strong sense of shock came to my face! My eyes widened and I couldn't close my mouth in surprise!

"Wow! What a majestic underground city! ”

I couldn't help but sigh, and I couldn't help but stop and admire. There was another cave outside the gate, but it was much bigger than the cave where Uptown was located!

The length and width of the lower city are hundreds of meters, about the size of a dozen football fields, and the highest part of the cave roof is also hundreds of meters, and there are hundreds of thick stone pillars between the cave roof and the ground, so there is no need to worry about collapse.

The terrain of the lower city is not as flat as that of the upper city, and many places still retain the topography of the original caves, with high platforms, potholes, and underground rivers. The general topography is the highest at the upper gate, overlooking the entire lower city, and the farthest point is the lowest, about 500 meters apart.

The lower city is full of shops, crowds, and bustling with strange buildings, some places like a labyrinth. Looking far to the far left of the lower city, there is a tall wall, and it is the only part of the city that has a wall. The wall is in a semicircular arc next to the cave wall, surrounded by a huge stone gate. The cave wall next to the stone gate is also full of charms and formations, and it is heavily guarded, I don't know what kind of place it is?

Zhao Laodao said: "Over there is Zemen, leading to Death." Dead Ze is an underground swamp, in which ghosts breed, there are all kinds of dangerous underground monsters and dead things in the underworld, and from time to time they will run over to harass and destroy. Therefore, Zemen and the city walls must be guarded twenty-four hours a day! ”

"Why don't you just seal this entrance?"

"Because the dead river is also the source of all kinds of livestock, resources, and minerals, Yin City regularly sends expeditions to go deep into the dead river to collect."

"What about the right side? Why isn't there even a door over there? I asked, pointing to a hole on the right. The hole on the right is bigger than the one on the left, but not only is there no city wall, not even a gate is installed, only some guards and officials are on duty and checking, which is similar to the gate checkpoint.

"It's the slave gate over there!" Zhao Laodao explained, "Behind the Numen is a long and wide Yin vein, which leads to several other Yin Cities, which is relatively safe. The Yin veins in the Numen are also mining areas, and tens of thousands of ghost slaves are driven in every day to collect the Yin Yuan, so it is called the Numen! ”

"What is the relationship between the other Yin Cities and Zuoqiu City?"

"It's all okay, after all, with the strength of Zuoqiu City, they can't afford to provoke it!"
