From the ground down to the first and second floors underground, there are special stairwells and lifting platforms, which are easy to find. However, if you go to the five floors below, you will have to hide a lot. However, this is a breeze for Ding Yi and them. Tens of thousands of puppet insects can easily lock on to some special characters and enter the various underground floors below.

Wudu is located in Wushan, at the intersection of Gangshan. It is not far from the largest deep-water port in the Black Iron Continent, Ul Port. The coal from Osan and the iron ore from Steel Mountain are all transported here and smelted by the steelworks here.

Although the steel produced by Wudu is not made of very good material, it is better in large quantities and cheaper. There is the Black Iron Continent here, the largest steel mill, and the largest group of industrial workers. There are tens of millions of mortals who depend on the steel industry to survive.

The first and second basement floors are the places where these mortals live. The greatest contribution made by the cultivators of the fog capital to this city is to arrange a circulating water treatment center in this city, otherwise, this city would not be able to stand for thousands of years.

Wandering in the dungeon and visiting this thousand-year-old city, Ding Yi was full of emotion.

There is a saying about fog, one layer is poor, and the second layer is rich. On the first floor, most of the people living there, are poor. In addition, there are many small and medium-sized workshops that are also located here.

Some low-level cultivators act as the administrators of the city and the underground, and they maintain the order of the underground city.

In the city, the law is very strict, the population here is relatively concentrated, historically, the city, there has been an outbreak of plague, so the management of the whole city, compared to other cities, is much stricter.

Wudu also has another name, called Cat City, this city has nearly hundreds of thousands of cats of all kinds. There are so many cats in the city, mainly to deal with mice. It is said that the plague of that year was spread by rats.

Xiao Hei transformed into a big dog, and Xiao Gray was held in Cai Meiniang's arms, and if she didn't look carefully, she couldn't see that this was a flying lynx.

A team of the investigation team is responsible for Ding Yi's actions, there were puppet insects exploring the way earlier, Cai Meiniang has already come here to wade through, Ding Yi and Cai Meiniang are still quite sure of their safety this trip.

Several important intersections and lifting platforms in the city are controlled by special cultivators, but these people are completely useless and useless to Ding Yi and Cai Meiniang.

You must know that Ding Yi and Cai Meiniang are illusionists, ever-changing, and these little soldiers of the Black Flag Army can't find anything at all. What's more, Ding Yi and the others didn't take the usual path, and directly used the space magic power to 'play through', and directly avoided them.

Ding Yi was on the top floor and stayed for a while. He was observing the life of the mortals in the fog. There are unique innate conditions here, and in addition, this fog capital city is also very suitable, as a fortress base operation, Ding Yi thinks farther.

Cai Meiniang followed Ding Yi to the mirage, and as Ding Yi's follower, she naturally guessed what Ding Yi was thinking.

The two stayed on the first floor for two hours, and finally, Cai Meiniang listened to Ding Yi say: "Here, although there are good congenital conditions, this is also the most difficult city to develop. The cultivators' control over this city is really too strict. Here, the fire of the puppet road has no possibility of burning at all, and it is difficult to succeed unless the manager of the fog capital is replaced by our own people. ”

Cultivators are almost invincible beings to mortals. This fog capital, which has a very good foundation, is difficult to develop because of this factor. The high-intensity management and strict laws make it difficult for the mortals of this city to have a bright future, and it is difficult for them to have other thoughts.

Ding Yi and Cai Meiniang did not deliberately transform into fixed characters, in fact, they changed all the way, all the way. On this street, the two may dress up as a boy and a maid, and on the next street, they will dress up as a couple, and on the next street, they will become grandparents and grandchildren......

Not only are they changing, but so are Black and Gray. Black Dog, White Dog, Flower Dog...... Kittens, bunnies, baby ......

Ding Yi and Cai Meiniang used illusion, and the 'ever-changing' along the way was actually Cai Meiniang teaching Ding Yi to learn illusion. As for Xiao Hei and Xiao Ash, the reason why they can also change with Ding Yi and them is because they are equipped with magic weapons that can release phantom arrays.

After Ding Yi's strength has greatly improved, he can make many miniature spirit arrays, which is a means of refining puppet insects. The miniaturization of the spirit array, combined with illusion, also made Xiao Ash and Xiao Hei have more changing forms, after all, Xiao Hei and Xiao Ash, they are also famous existences in the cultivation realm.

After Ding Yi's strength has greatly improved, his means and abilities can be said to have made a qualitative leap compared with two or three months ago.

The fifteen main qualifications, especially the eye spirit qualifications, have reached the intermediate level of the Xuan level, which is really of great help to Ding Yi. What's more, he created a god brain. This made Ding Yi's followers weaken their strength because of the spiritual magnetic storm, and because of the substantial growth of Ding Yi's personal strength, he equipped his followers with higher-end magic weapons and war puppets, which made their entire strength rise instead of falling, and increased by several levels.

Cai Meiniang's qualifications have not been fully restored, she is now a high-level Xuan, but her overall strength is several times stronger than before.

As a puppeteer, she carries a Terminator on her body. In addition, inside her storage bracelet, there are five Xuan-level war puppets and a hundred 'Hidden Wolf Bee' puppet insects.

Cai Meiniang is now following Ding Yi wholeheartedly, and she has long lost her half-hearted thoughts. Ding Yi's strength and potential are all in her eyes.

It's a pity!

Ding Yi and Cai Meiniang, walking on the basement floor, felt a lot of emotion in their hearts for the largest city in the northeast.

"Isn't it okay to introduce the Creation God Cult?" Cai Meiniang suggested.

Ding Yi shook his head, the mortals of the fog capital, because of the unique environment here, under the high-pressure rule of the cultivators, for thousands of years, they were like beasts that were raised, gradually degraded into wildness. Mechanical, numb, day after day, year after year, repeating the trajectory of the father's generation. They are a group that has been thoroughly domesticated, carried out, and ideologically castrated.

Cai Meiniang could see that Ding Yi was real and wanted to help these mortals. The longer I spend with Ding Yi, the people around Ding Yi, under the subtle influence of Ding Yi, have gradually accepted Ding Yi's idea of 'all beings are equal'.

Among mortals, there are people with outstanding talents like Dai Xiaoxue, Ding Siqi, and Han Jiahui, and there are also mortals like Yang Jiabiao, who behave very ordinary. Through a period of contact and understanding, everyone has long changed their previous attitude. In addition to these companions around them, they can also uphold a tolerant attitude to face those mortals who were previously disdained by them.

In particular, everyone went on a mirage. The people of the mirage, especially the common people on Redstone Island, brought a lot of shock to everyone's hearts. The kind of fearless courage to die generously for the sake of faith and ideals, throwing away their heads, and spilling their blood, made these cultivators can't help but begin to examine themselves, and gradually change their attitude towards mortals.

The purpose of coming to Wudu this time is mainly to rescue Long Yan and Lan Xuan. At the same time, Ding Yi also tried to meet with the leader of the Black Flag Army to see if he could pull the Black Flag Army and Wukui into his camp.

As for the mortals of the Fog Capital, with the current situation, in the short term, there is no way to change the situation here.

There is a gap of more than twenty meters between the first and second floors, and in some places, there is even a depth of only seven or eight meters.

Ding Yi and Cai Meiniang are not on the beaten path. They avoided the various low-level guards of the Black Flag Army, directly activated the spatial supernatural powers, and entered the second layer.

Coming to this underground city, Ding Yi also has a purpose, which is to test Xiao Hei's spatial traversal ability, because until now, Ding Yi still doesn't know how much Xiao Hei has recovered.

Ding Yi has not yet tested how thick the rock layer Xiao Hei can pass through now, and this trip to the fog capital is actually a preliminary evaluation of Xiao Hei in advance.

You must know that Xiao Hei is at his peak, but he can pass through more than 3,000 meters thick rock layers, how much has his current strength recovered?

Xiao Hei is the key to returning to the underworld, and if it hasn't recovered most of its strength, everyone will have to stay in the surface world for a while.

One floor is poor, and the second floor is rich. The second layer, in every way, is quite a bit stronger than the first. Although the dungeon part of this fog capital is decorated everywhere, all kinds of glowstone lamps imported from the Shenwu Empire. But it can still be seen that the light on the second basement floor is obviously much brighter than the first floor. The living environment here has also improved a lot compared to the above.

On the second floor, there is the commercial area of Wudu, and the high-end living area. The space on the second floor is very high, fifty or sixty meters long. There are also many trees and flowers planted here. The population of the first layer accounts for almost ninety or five of the fog capital, and there are many people in the second layer, no matter how you look at it, there are hundreds of thousands.

There is a prosperous business here, with shops, gambling halls, green buildings, and wineries. The lights are bright, and on the street, the clothing of the personnel is obviously much brighter than the first layer.

At this level, there were obviously a lot more cultivators in the crowd. But I can still feel that this is the mundane mortal world. The consumer groups faced by various businesses are mainly mortals. However, with the size of the fog capital, its prosperity is far from catching up with Jiyun City.

Ding Yi didn't stay at this level for too long, he took Cai Meiniang and went directly to the third layer.

In the first two floors of the fog capital, there are many thousand-year-old buildings, and the third layer is obviously not so old, at most, it is more than 200 years. This is the station of the Black Flag Army, and it is the underground floor where the various Xiuzhen families live. The population here is even smaller, probably no more than 50,000 people. Here, it's probably the cultivation realm circle of the fog capital.

The main body of the third layer is the natives of the fog capital, but there are still some cultivators who come to the fog capital from other places.

Ding Yi and Cai Meiniang did not follow the normal procedures to enter the third layer, the people of the Black Flag Army, they didn't know at all that there would be monks who used their magical powers to mix in.

At every level, there are a lot of cats and dogs, and Ding Yi and they brought Xiao Hei and Xiao Gray into here, and they didn't look very different. The monks that Ding Yi and Cai Meiniang transformed into are all the kind of public faces, and their clothes are very high-end, but ordinary monks can't see the doorway.

In fact, in this city, it is also impossible that someone will be able to recognize it. Because this is the latest type of cultivation material refined by Wu Hong from the seaweed using cultivation technology, Zhen Zhen gave it a name, called 'sponge'.

'Sponge' is combined with other cultivation materials, refined according to the secret method, and finally, it is Ding Yi and Cai Meiniang, who are wearing the 'Divine Variety Clothes'.

Liu Chengzhi noticed these two seemingly ordinary middle-level cultivators almost immediately. Out of professional instinct, he always felt that there was something wrong with these two monks.

Liu Chengzhi is the deputy leader of the dark group, and they are the first special service team to rush to the fog capital after receiving the news.

The various groups of the special service, stationed in various overseas continents for a long time, the Black Iron Continent, have always been the main area of activity of the dark group. Liu Chengzhi and they are very familiar with the fog, and they have long figured out the reality of the fog capital, including the various paths of the seven underground layers of the fog capital.

The strength of the special service group is already high, and in addition, their group is a cultivator who mainly has dark spirit qualifications. Surveying the subterranean city was a breeze for them. What's more, the people who control the city are still their own people.

Liu Chengzhi found out about Ding Yi and them, but he didn't know that long before he found Ding Yi and Cai Meiniang, he was identified by the investigation team as the object of close monitoring. Who let him carry the identity spirit rune of the Shenwu Empire on his body.

Ding Yi and Cai Meiniang, mingling in the crowd, were inconspicuous, but they still attracted the attention of this secret service monk. Liu Chengzhi has been in the Black Iron Continent for so long, so he naturally knows a lot of monks from the Black Iron Continent, and in this fog capital alone, there are many people who know this Liu Gongzi who often travels everywhere.

Liu Chengzhi summoned a native monk from the fog capital. He lowered his voice and said, "Little Brother Qin, do you know the two people in front of you?" It was the young man holding a gray dog, and the girl holding a kitten beside him. ”

The indigenous monk looked at Ding Yi and Cai Meiniang and shook his head.

Liu Chengzhi continued: "You hurry up and inform a few commanders, I suspect that these two people are spies of the Demon Kingdom, I seem to be believing in the end of the world, seeing them, and being with the people of the Demon Kingdom." ”

Brother Qin was convinced of Liu Chengzhi's words. He hurriedly called the garrison here and reported the information of Liu Chengzhi's reaction. Liu Chengzhi stayed behind the two unhurriedly and continued to follow and observe the two.

Not long after, Brother Qin rushed over with more than a dozen monks from the Black Flag Army.

The illusion of avatar is a very simple thing for a cultivator. The information that Brother Qin reacted quickly spread to the monks who were guarding the stairwells and lifting platforms.

As soon as the news of 'no such person found' came, this group of monks stationed there could no longer hold back and hurriedly chased after them.

"Those two people, I saw them enter the tea house, I have been guarding the door, I didn't see them come out, you go in and have a look. "Liu Chengzhi's hand is skillful in killing people with a knife. This group of more than a dozen monks hurriedly rushed in.

But soon the group came out of the tea house.

If they hadn't discovered that Liu Chengzhi was strong, it was estimated that someone would have been unkind to Liu Chengzhi when they landed.

Liu Chengzhi was taken aback, he was a Yuan-level master, although there were indeed some spiritual arrays in the teahouse that isolated the divine sense, but he was guarding outside the teahouse, and there was only one entrance and exit of the teahouse.

Liu Chengzhi still can't believe that someone will play 'big change of life' under his nose. He hurriedly entered the tea house, just as the results of this group of Black Flag Army exploration sites. These two people, a cat and a dog, disappeared into the teahouse alive.

There are endless secret methods of cultivators, and it is not clear what kind of magical powers the other party uses, but there are two eyewitnesses to this matter, the monks of the Black Flag Army, still chose to believe the words of Liu Chengzhi and Qin Xiaoge, and they hurriedly reported to the above, and then most of the personnel of the Black Flag Army on the third layer received the news and began to make every effort to find the monk with a man and a woman with cats and dogs.

Liu Chengzhi originally just wanted to get to the bottom of the matter, but he didn't expect such a thing to happen, he was a little discouraged, and at the same time he was very curious.

Could these two people be the targets of their investigation? Or are these two just people from the Demon Destroying Dao Alliance, such as Wukui and Demon Slayer? Liu Chengzhi was still unsure, and he also took the initiative to help find out, but he still found nothing.

Liu Chengzhi felt more and more incredible.

"Big brother, someone asked me to give this thing to you. A little girl jumped up and down to Liu Chengzhi, holding a sugar gourd in her left hand and an origami in her right hand.

Liu Chengzhi reached out to pick it up, and the little girl's little hand handed over the origami retracted again.

"Big brother, big sister said, this letter is worth ten magic yuan. The little girl said with a smile, and between her eyebrows, the appearance of a little wealth fan was undoubtedly revealed.

Liu Cheng's heart moved, and he hurriedly took out ten gold dollars from the Shenwu Empire from his body and handed them to the little girl. The little girl also kept her promise and handed over the origami to Liu Chengzhi.

There is only one sentence on the origami, and a pattern of a cat and a dog.

'If you want to see us, follow Sister Xiaoxue.' ’

Why did a little snow sister come out again, could it be the little girl in front of her?

"You're Xiaoxue, right? The letter said that you want you to take me to meet them. Liu Chengzhi leaned over and said to the little girl.

The little girl nodded generously and said, "Yes, I am Xiaoxue, but the eldest brother wants me to take you there, and he will give me another ten magic yuan." ”

Liu Cheng's art is bold, he was not frightened by the elusive supernatural powers of the young man and woman, he took out another ten gold yuan according to his words.

The little girl smiled and said to Liu Cheng: "Come with me." Jumping up and down to lead the way, Liu Chengzhi hurriedly followed.

Along the way, Liu Chengzhi mobilized his divine sense, carefully searched the surroundings, and did not dare to let go of any clues, he also observed the little snow girl who led him the way, but he didn't find anything, this little girl who was greedy for money seemed to be an ordinary little girl, nothing special.

After going around and around for a while, Liu Chengzhi suddenly found that the little girl had gone around in a big circle and took him to the teahouse.

Liu Chengzhi couldn't help but hesitate.

"Big brother, big sister, let you go to see him alone, if you call someone, they won't see you. Xiaoxue seemed to have guessed Liu Chengzhi's thoughts, and took the lead in blocking his retreat.

"Xiaoxue, are you very familiar with the big brother and big sister, why do they ask you to help them run errands?"

Xiaoxue tilted her head and thought for a while.

"You're giving me ten magic dollars, and I'll tell you. ”

Liu Chengzhi frowned, he didn't care about this bit of gold yuan, and besides, he had already arrived at the door of the teahouse, he ignored the little girl and walked into the teahouse again.
