Whether it is the Four Elephants and Seven Yao, the Twenty-Eight Star Transformation Array, or the Seven Yao Heavenly Array, this needs to be carefully considered.

Ding Yi was deducing the formation here, and a strong sense of uneasiness suddenly arose in his heart. He quickly hid on the roof of the toilet again......

A super obese man broke into the toilet, this guy was as huge as a mountain of meat, Ding Yi guessed that this guy should weigh six or seven hundred pounds. If it weren't for the fact that this guy was a cultivator, Ding Yi would even doubt that this guy would be able to walk.

At this time, Ding Yi finally understood why there was a cubicle in the toilet, which was surprisingly large.

"Fat Dragon, you can't, it's convenient when you're not on duty, it's convenient when you're on duty every time?" someone outside the toilet complained.

"Old man, this is in charge of heaven and earth, you still care about people shitting and farting? Wait for me for ten minutes, and it will be fine right away. The fat man gasped and said loudly.

"Fatty, hurry up, every time you say ten minutes, it's almost half an hour each time, we won't wait for you, you move quickly." Outside the toilet, another person complained.

The fat dragon smiled and said, "Why don't you all come in and squat together?"

There was a curse coming from outside the toilet.

Gradually, the curses faded away, and the fat dragon's originally smiling face retracted the smile.

This fat guy is not simple. Ding Yi was silently observing this fat dragon.

A mirror-shaped magic weapon suddenly appeared in the fat dragon's hand, and the fat dragon was carefully observing. Ding Yi was on it, and he could see it clearly, and above the mirror, there were four green points of light moving.

Feilong put away the mirror, and the next moment, he was like a balloon that had been deflated, and his whole person shrank sharply, and finally turned into a middle-aged man with a normal body and a slight thinness.

This fat guy is weird! Could it be that he is a peer?

Thinking of this, Ding Yi felt an inexplicable joy in his heart.

This toilet is a dead end in the inner city, Ding Yi can use the knowledge of the formation to deduce this, why can't others? If this fat dragon is also the same way, maybe it is also based on the same reason.

It is very likely that these Xuan-level guards are a room for several people, and the fat dragon can't start from his residence, so if you think about it, there are only a handful of places for him to act conveniently.

This is really the same thing that a hero sees! Ding Yi thought secretly.

You must know that the Tibetan Scripture Pavilion of the Heavenly Dao Gate is an existence that even the Shenwu Empire covets, and it is impossible for the collection of books in it, with the urine nature of the Shenwu Empire, not to have touched this crooked brain. Of course, the possibility of other forces cannot be ruled out.

This treasure of Lan Hanxing is an existence that everyone wants to touch. Ding Yi decided to stand still for the time being and observe the movements of this fat guy.

The fat dragon's movements were very fast, he quickly took off that body, and for him now, the clothes that were too bloated were replaced with a new outfit.

The fat dragon took out the mirror-like magic weapon again, and looked at it carefully, this is a very cautious person.

The fat dragon was just about to collect the magic weapon and start working, suddenly, as if his whole person was frozen, he slowly raised his head and looked at the shadow where Ding Yi was hiding.

The cultivation technology of the Tianjing Continent has not been able to refine the glow stone, which replaces the lighting at night, but the rampant smuggling still makes the Shenwu Empire now become a cabbage price of glow stone, and a large number of them have entered this land.

The toilet is also filled with glow stone, Ding Yi chose a corner with dim light, but he didn't expect that the magic weapon in Feilong's hand would have such a powerful detection function. It also has the function of 'breaking delusion'.

In fact, this is not how powerful the magic weapon in the hands of the fat dragon is, but the magic weapon is originally more sensitive to spiritual power, and illusion is also a form of spiritual power, it acts on people, affects people's perception, and makes people hallucinate, but for cold magic weapons, it can't change the detection results.

Ding Yi didn't expect that his illusion would be broken by this magic weapon. There is no point in hiding it anymore. He jumped straight from above.

"Hello fellow Dao!" Ding Yi was wearing a helmet and covered in armor, making it impossible to see his true face.

Both of them have evil intentions, but they don't do anything to each other, they just observe each other.

"We have the same purpose and can work together. Ding Yi said suddenly.

The fat dragon thought for a moment and agreed. None of them went to the bottom of each other's details. Presumably both of them know that the other party will not tell the truth.

The fat dragon didn't talk much nonsense, and started to act directly.

"Move!" the toilet urinal suddenly moved slowly to the side, revealing a black hole that was only slightly larger than a human head. If it weren't for the fat dragon opening this mechanism, who knew there would be such a cave here. The fat dragon glanced at Ding Yi coldly and made a move to make Ding Yi jump down.

Ding Yi was not ambiguous, and jumped directly.

It's a long tunnel, the hole is narrow, and I don't know where it leads.

Like riding a slide, it fell for a while before Ding Yi's feet came into contact with the ground. Ding Yi estimated that this cave, to say the least, was 100 meters high from the ground. Overhead, Ding Yi heard the sound of the urinal slowly closing, and soon heard the sound of the fat dragon sliding down.

The vertical part has been completed, and a horizontal hole is at his feet, Ding Yi didn't need to be commanded by the fat dragon, and directly bent down and crawled forward.

Ordinary tunnels will have ventilation ducts, but this cave does not, because the work is a cultivator, and they are not ordinary mortals.

Ding Yi moved forward quickly, and the more he crawled forward, the more frightened he became, although he couldn't see his five fingers in the cave, it was pitch black. However, Ding Yi has the qualifications of dark spirit and eye spirit, and he can see it clearly. It was surrounded by granite stone walls. Ding Yi also finally understood why the Heavenly Dao Gate set up the secret vault in this golden city, it turned out that the geological structure here was like this.

The length of the inner city is 4.3 kilometers, and the widest part is 1.7 kilometers, which resembles an oval-shaped bird's egg. Jincheng is a geographical pattern by the mountains and rivers, and the inner library is probably built in the mountains to a certain extent. However, those who are familiar with history know that this mountain is actually made by excavating the soil and stones of the basement.

This man-made hill two or three hundred high is likely to cover the ground part of the basement, but the basement will never be in the mountain. Moreover, there are many mechanisms on this mountain, and there are countless magic circles, and there are not a few people guarding this hill.

Most of the inner library was still built in the inner city. As for why, the fat dragon and the forces behind him did not dig from the outer city, and it is estimated that this has something to do with the structure of the outer city. On the surface, the outer city is mixed with various forces, but the management of the outer city is loose on the outside and tight on the inside, and the forces that enter the outer city are actually subject to the review of the Heavenly Dao Gate at all levels, and there are all kinds of monitoring methods in the outer city that are not known to outsiders.

From the gate to the toilet next to the restaurant, there are almost seven or eight hundred meters, and Ding Yi doesn't know what the process of this tunnel dug by Feilong is. Of course, Ding Yi hopes that Feilong has better dug into the basement, so the only thing to do is how to break the basement.

However, after climbing four or five hundred meters, this tunnel has come to an end, and it is not known where the basement is.

The tunnel is very narrow, but Ding Yi has practiced physical arts, and his flexibility is enough, he turned around at the end of the tunnel, and the fat dragon also crawled over at this time.

"How far is it from the basement?" Ding Yi asked Feilong.

Fat Dragon said: "This has nothing to do with you, the dead don't need to know all this." ”

Ding Yi said: "Wouldn't it be better to have one more helper?"

Feilong sneered: "Lao Tzu took over this secret passage and dug hard for more than two years, you say, will Lao Tzu agree to let you get a piece of the pie?"

Ding Yi suddenly understood the fat dragon's thoughts, obviously this is a guy who wants to eat alone. In fact, it is easy to understand that a person is so painstakingly and persevering in this inner city. He has to live like a mouse every day, and he really won't let a mysterious person like Ding Yi who suddenly appears share the treasures of the Heavenly Dao Gate with him.

In the toilet, Feilong didn't want to do anything to Ding Yi, probably because he was afraid of exposing his secrets, and when he got to this underground, he had no scruples, which was Feilong's plan.

"Your spiritual sense, you can't not be unaware that there is something behind you, right?" Ding Yi was not afraid, he dared to jump into it alone, this stinky tunnel, he couldn't have left his hands behind.

The fat dragon's body stiffened, and he really noticed the abnormality behind him.

"What's that?" asked the fat dragon.

"Thunderbolt, a small but effective bomb, a small thunderbolt, in such a small space, can be blown up enough, even your own mother will not recognize you. Ding Yi said.

The fat dragon was silent for a long time and said, "Who are you? What do you want?"

Ding Yi said: "It doesn't matter who I am, just like you, everyone has the same purpose, cooperation is two benefits, and fighting is two defeats, you weigh it yourself." ”

The fat dragon didn't think about it for too long, and after a while, he nodded.

"Cooperate. ”

The fat dragon finally chose to give in. The two quickly came to an agreement. At this point, it would be stupid to have another infighting.

"Are you sure of the location of the inner library? How long will it take to dig it? Excavate the tunnel, what should I pay attention to?" Ding Yi asked a few questions.

The fat dragon took out a piece of glyphite, and the tunnel suddenly lit up. Then, he took out a jade talisman with a simple style and threw it directly.

"Let's exchange information!" said Feilong to Ding Yi.

Face to face and close observation, in fact, this fat dragon is not too ugly, not only is he not fat, but on the contrary, he is a little thin. The secret method that his hand made himself bloated and unbearable was really hard to believe that the fat dragon would be such a thin man in front of him.

Ding Yi took the jade talisman, as a puppet master and array mage, as soon as he got his hands on this jade talisman, he knew how to operate it. He fiddled with the jade talisman a few times, entered a spiritual power, and suddenly the entire structure of the inner city appeared in front of Ding Yi in the form of an illusion.

This jade talisman is very old, and it is likely that it was made by a monk who built the basement at that time.

Not only because this jade talisman looks quaint, but also because of this jade talisman, there are not as many inner city buildings as there are now. Obviously, with the passage of time and the progress of Xiuzhen civilization, Jincheng has added a lot of modern collections, and many new libraries have been built on the ground.

Ding Yi looked at the illusion for a few seconds, and he quickly came to the conclusion that this was a genuine product, and the direction of the fat dragon's excavation was not wrong. The only pity is that the basement is still not a short distance from here

The fat dragon threw the jade talisman to Ding Yi, showing his attitude of cooperation, which was a good thing, but Ding Yi didn't have any information to exchange with him.

Ding Yi returned the jade talisman to the fat dragon. He shrugged his shoulders and told the truth.

"I have no intelligence. ”

"You're fooling me!" roared the fat dragon.

Ding Yi waved his hand, and he took out the flying lynx puppet.

"What the hell is this?" asked the Fat Dragon.

This thing looks like a tiger, a leopard, and a cat, a winged tiger, a clouded leopard, and the fat dragon doesn't know, what Ding Yi wants to take out such a thing.

"You don't care what it is. Pay attention to its claws, this is Otitanium, sharpened like clay, I don't know how much work you and your predecessor have done, and when it comes to me, this kind of turtle speed is not good. Ding Yi said.

In this underground tunnel, all super-powerful and powerful spells cannot be used, so as not to alarm the guards of the inner city. You can only use physical methods, little by little......

While the fat dragon was skeptical, the flying lynx puppet had already started working. Under Ding Yi's control, the four claws of the flying lynx puppet dug up quickly, and in the blink of an eye, a stone chip appeared in the hole.

The fat dragon was dumbfounded.

"Still stunned what to do, hurry up and dispose of these stone fragments. Ding Yi commanded.

Only then did the fat dragon come to his senses, he had several storage bracelets on his body, and hurriedly loaded these broken stones with Ding Yi, and then returned along the road.

"What do you usually do with these excavated stones?" asked Ding Yi.

Fei Long said: "Every time, I crush the stone into stone powder, and then use the toilet sewage system to wash it away with water. ”

Ding Yi said: "In this way, you stay on top, responsible for gravel and flushing, and I am below, responsible for digging and transporting gravel, and the speed of excavation will come up." Remember, if you want to wash away the water flow of stone powder, you must have a lot of water, otherwise it will cause siltation, and we will lose all our efforts when we get out of the way. ”

The fat dragon nodded. He casually handed Ding Yi three storage bracelets, and Ding Yi was not polite, took them, turned around and went down the tunnel again.

After the division of labor was clear, the two thieves went all out and began to work with their lives.

In twenty minutes, Ding Yi excavated at least three or four cubic meters of stone. That's almost a month of Wyvern's achievement.

"I'm leaving, I still have a night mission. Feilong estimated the time and said to Ding Yi.

Ding Yi said: "Go ahead, one person here will do it." ”

Feilong glanced at Ding Yi in a complicated way, and changed back to the original Roshan-like image.

"Pay attention to yourself. The fat dragon looked at Ding Yi, who refused to show his true face until now, sighed softly, and turned to leave.

Ding Yi returned to the tunnel again and began to work intensely.

According to the information provided by Feilong, this tunnel will be dug for at least another two kilometers, which is a difficult project, if it is just excavation, it is better, the key is to deal with these excavated stones.

Ding Yi has a headache and that's not all, he only has five days left. Although both Steward Hong and Rong Cai agreed to help him, in order to be able to connect his time perfectly, it is not only necessary to have a reasonable arrangement, but also to have excellent luck.

Ding Yi is sure that in about twenty days, this tunnel will be dug to the basement, but will God give him so much time?

Ding Yi released the general puppet, the job of this puppet is to grind the stone into small particles of powder, but this general puppet has a drawback, that is, it is only made of ordinary steel, Ding Yi has no guarantee that this general puppet will not fail halfway.

In the ghost place of the inner city, in addition to books, it is still books, and it is difficult to find a few pieces of ironware, and in case of failure, there is no way to prepare the replacement parts.

Sure enough, after three or four hours, the general puppet quit work. Ding Yi had to slow down the speed of the excavation, and he asked the flying cat puppet to try to make the stones as fine as possible when digging the stones, and he smashed the stones again with his fists.

Throughout the night, Ding Yi was busy in the tunnel like a tireless mouse, and he was busy until morning, when it was almost five o'clock, and Ding Yi ended the night's work. He became invisible again, and soon heard the sound of doors and windows opening and tapping footsteps everywhere.

There were people coming in and out of the toilet all the time, and it was easy for a short time when there was no one, Ding Yi hurriedly came out of the shadows, walked out of the toilet and blended into the crowd.

This night, he dug about a hundred meters. It's still very early to dig into the basement.

At breakfast, Ding Yi and Rong Cai met.

"Give me all your weapons. Ding Yi commanded everyone. Ding Yi also didn't explain to them what it was for.

Rong Cai and the others were inexplicable, but they still obediently handed over their weapons: swords, sabers, and coiling dragon sticks.

Rong Cai's weapon is a jade fan, this thing is useless to Ding Yi, he didn't accept it, and he put other people's weapons into the storage bracelet. After a few words of instruction, everyone dispersed.

The consumption at night was very large, and in the morning, Ding Yi let go of his stomach and ate several plates of braised beef, seven or eight turkeys, and finally replenished some physical strength.

Walking out of the restaurant, Ding Yi returned to Wuxuan Hall again, this time he still found a room casually like yesterday. But this time he didn't come to see the book, he was very tired, and he came in to find a place to sleep.

He picked up a large book from the shelf, walked to the table, put the book up, lay on the table, and fell asleep after a while.

When he came to the inner city, he didn't hurry up to cultivate, but slept here, and it is estimated that Ding Yi is still the first one.

Soon, the corner gate of the inner city opened, and a group of newcomers poured in......
