......

For the indigenous inhabitants of Zixiao City, this winter is more comfortable than any season in previous decades.

Since Ren Wankut was killed by the current city lord of Zixiao City, the poisonous gas that pervades all year round can no longer affect people's daily life, and people can breathe freely under the fresh air without worrying about the poisonous gas entering the body, causing various diseases and deaths. Even, in such a dark killing place as Dark City, Zixiao City as an alternative subverted the previous people's definition of Dark City.

Here, there is no more killing, no more fighting, people live quietly and peacefully, and they don't have to worry about the scenes of fighting and killing every day. Ordinary civilians can cultivate and weave, and martial cultivators can find a secluded place to meditate and practice with peace of mind. The entire Zixiao City presented a quiet and peaceful scene.

Of course, all of this is thanks to the new gang of Zixiao, which in people's hearts is like a savior, bringing them a prosperous and healthy life. Therefore, don't look at the Zixiao Society, which has wantonly eradicated the poisonous sect, and even destroyed Zixiao City, but people are still happy to see this kind of sect that preaches justice appear.

All of a sudden, the prestige of the Zixiao Society and Ou Chuyang spread far and wide, and even the residents of the neighboring towns began to migrate to Zixiao City one after another.

Don't look at the great battle a few days ago, which brought huge losses to Zixiao City, and even the population was drastically reduced due to the fight of the two powerhouses, but it didn't take long for Zixiao City to once again restore the scene of a medium and large city with a surging flow of people.

At this time, the poison gate has already updated its intentions and changed its appearance into the appearance of the Zixiao Society.

In Ou Chuyang's residence in the backyard, Ou Chuyang stood alone in the center of the courtyard, standing with his eyes closed. Around him, there are colorful spirit crystals everywhere, from the first level to the five crystals, all kinds of colors, all sprinkled on the ground, the whole courtyard seems to be paved with colorful gems, it is very beautiful.

Of course, this spirit crystal all over the ground was not used as a paving stone, he was asked for by Ou Chuyang from Bauhinia in order to facilitate the study of the formation realm.

Originally, the Zixiao Society didn't have so many spirit crystals, but in the battle before the crystals, the number of people who died in the poison gate was too much. When it was those ordinary martial cultivators, under Ren Wanku's powerful martial arts, they turned into cold corpses. At that time, all the spirit rings all over the ground were collected by Zixiao, and nearly a hundred spirit rings naturally stored a large number of spirit crystal treasures, especially among the spirit rings that Ou Chuyang had found, there were hundreds of spirit crystals above the third level. Obviously, how many treasures this old ghost has collected over the years.

"Concentrate and calm your breath and feel the fluctuations of the aura of heaven and earth. You have to remember that the formation boundary is an independent space created by borrowing the power of the five elements of heaven and earth, and integrating the two into one according to the established formation and boundary law, in this space, there must be a force to maintain the formation of space, and this force can be formed by internal gas, or it can be acted by the power of the soul, which is what we call the array eye..."

In his soul, Wang Zhen stated word by word, and he was afraid that Ou Chuyang would not be able to comprehend it, so he deliberately said it a few more times. It wasn't until Ou Chuyang had everything in mind that he continued.

"The formation realm is ever-changing, there are no special rules, it all depends on how the cultivator perceives, what speed he perceives, the formation created by each person is different, if you want to cultivate into an array that you can create at will, you must understand the truth of heaven and earth, which is what martial artists often say. ”

For several days, Ou Chuyang was almost completely integrated into the obsession with the battle world, to say that Wang Zhen really deserved to be the god of the formation world, the basic knowledge he taught was almost immediately understood, and even the complicated big array, after Wang Zhen's explanation, coupled with Ou Chuyang's own scrutiny, could be easily understood.

In a few days, Ou Chuyang basically memorized the four major formations in the formation realm, namely "Phantom Array", "Maze Array", "Killing Array", and "Imperial Array". Next, it will depend on Ou Chuyang's own efforts.

After countless deliberations in his mind, and then placing the spirit crystal for field exercises, after countless failures, Ou Chuyang gradually mastered the tricks, and it was much easier to set up the formation again. Among them, Ou Chuyang's favorite is the Phantom Formation Technique, which can be easily performed without materials and with only internal qi and soul power. After all, the Wraith Formation is most effective in actual combat.

In addition, Ou Chuyang also had a soft spot for the wonderful method of the teleportation array. In order to learn this strange formation as soon as possible, Ou Chuyang squatted on the ground and drew a six-pointed star for two days. But there is still no way. For this reason, Wang Zhen also ridiculed Ou Chuyang.

On this day, Ou Chuyang, as usual, raised a branch and drew on the ground. In the distance, Xu Jie'er walked over slowly.

Seeing Ou Chuyang squatting on the ground and concentrating on drawing something, Xu Jie'er did not make a sound to disturb, but approached gently.

When she got closer, Xu Jie'er couldn't help but be shocked when she looked at the ground.

"Array?"

A coquettish shout interrupted Ou Chuyang, who was practicing, who raised his head and looked at Xu Jie'er in surprise and asked, "Do you know?"

A misty light flashed in Xu Jie'er's eyes, and she finally nodded.

Now, it was Ou Chuyang's turn to be surprised.

Standing up slowly, Ou Chuyang clapped his hands and said, "Jie'er, I think you know a lot of things." ”

The slightly ridiculous words came out of Ou Chuyang's mouth, but they implied an inquiry, Ou Chuyang looked directly at Xu Jie'er, his eyes showing anticipation.

Of course Xu Jie'er is not stupid, he can see that Ou Chuyang is deliberately asking about his identity, and he is embarrassed to speak.

After getting along for a few years, the two have long been good friends, and even Ou Chuyang doesn't know that Xu Jie'er's heart has long been captured by him.

Struggling, Xu Jie'er couldn't bear to say: "Ou Chuyang, I know you are very curious about my identity, but please forgive me, I can't say it now, when the opportunity comes, I will naturally tell you." Okay?"

Experiencing the embarrassment in Xu Jie'er's words, Ou Chuyang nodded happily and said, "Hehe, it's nothing, you also said it, I'm just curious, we are friends, I won't force you to say what you don't want to say." ”

Hearing this, Xu Jie'er closed her lips and bit her lips, at this moment, he wanted to tell his identity, and even the feelings that were pressed in his heart wanted to be revealed, but in the end, Xu Jie'er still held back.

Ou Chuyang is such a shrewd person, of course he can see Xu Jie'er's inner entanglement, so he hurriedly changed the topic and asked, "Come to me?"

Seeing that Ou Chuyang diverted the topic, Xu Jie'er nodded gratefully and said, "Black Rock City sent an invitation to invite you to gather in Dark City." ”

"Haoming?" Ou Chuyang heard this, and his calm expression appeared a dignified look.

The Dark City, which has been synonymous with devastation and chaos since ancient times, no one knows how long it has been standing on the mainland, and people can only guess its history through the mottled ancient city walls.

The Dark City does not have a clear sense of overlord, and the people who have lived here for a long time have passed down their memories of the Dark City from generation to generation is that this darkness has always been occupied by the four forces, and people don't know how many faces the four forces have changed, in short, this dark city has never belonged to anyone.

Standing under the towering dark city, Ou Chuyang felt the shock brought to him by this ancient city with a long history with an upward gaze, and sighed.

"It's a big city. Looking at the majestic city wall in front of her, Xu Jie'er showed surprise for the first time, and sighed: "I have long heard the seniors in the clan say that the dark city is one of the largest cities on the mainland, but I didn't expect it to be so big, who built it." Such a large city can accommodate hundreds of thousands of people, to say the least. ”

"Yes. Beside Xu Jie'er, Ou Chuyang stood with his hands in his hands and said solemnly: "Indeed, the huge size of this dark city has exceeded our imagination. It's really hard to understand that there is no one to rule such a big city. ”

"It's not that no one rules, it's that no one dares to rule here, and no one has the ability to rule here. Xu Jie'er smiled, as if she knew some of the details of the dark city, and said: "I heard from my predecessors, this dark city has had this rule since ancient times, no forces are allowed to set foot in the dark city, and if you want to occupy a place here, you can do it, but if you want to occupy this place and become a hegemon, it is an act of crossing the line." ”

"Crossing the boundary?" Ou Chuyang turned his head, looked at Xu Jie'er suspiciously, and asked, "How to cross the boundary?"

"Unbounded?" Xu Jie'er smiled meaningfully, as bright as a chrysanthemum, and said, "Haven't you heard of the Dark City, also known as the City of Freedom. Here, people have absolute freedom, you want to kill people, you can. If you want to rob, you can too. In short, as long as you come here, as long as you have the strength to save your life, no one will care about whatever you do. However, there is only one rule here that no one can ignore. ”

"What rules?" asked Ou Chuyang.

"Don't try to take this place. Otherwise, the wrath of the Four Kings of Darkness will be met. Xu Jieer replied.

Listening, Ou Chuyang shook his head slightly, and sneered: "The Four Kings of Darkness, but they are also martial arts-level powerhouses, I don't think they have much deterrent power. ”

"That's right. Xu Jie'er raised her eyebrows and said softly: "The strength of the Four Kings of Darkness is too weak, not enough to make people feel palpitations. ”

Ou Chuyang deeply agreed with Xu Jie'er's words, after all, the huge brave martial arts continent, there are countless strong people, just the realm of martial madness, it is not enough for an ancient city to maintain a peaceful state for many years, maybe there are any secrets in it.

Looking at Xu Jie'er, Ou Chuyang felt that there was something in the former's words, so he bowed his hand and said with a look of asking for advice: "What else do you know? Let's hear it, so that the kid can have a long experience." ”

Seeing Ou Chuyang's humble appearance, Xu Jie'er was very satisfied, snapped her fingers, Xu Jie'er pretended to be profound: "Even if you know each other, I'll tell you." ”

"Oh?" Ou Chuyang was stunned when he heard this, and couldn't help but suspect in his heart: "What is it that even the Four Kings of Darkness don't know?"

"At least you, one of the four kings, know, hee-hee. Xu Jie'er Jiao laughed.

"Uh" Ou Chuyang smiled bitterly and shook his head, he didn't expect that Xu Jie'er would actually put herself in this place. But he knew that Xu Jie'er was right, when it came to understanding some secrets on the mainland, not to mention Xu Jie'er, even if it was a figure like Fang Tang, he couldn't catch up. Therefore, Ou Chuyang was just stunned for a moment and did not refute.

Seeing Ou Chuyang's old-fashioned appearance, Xu Jie'er was deeply bored, pouted, and muttered "elm head" before she said solemnly: "I heard the seniors of the clan say that this dark city must be at least a thousand years old, and it has been renovated countless times before it becomes so majestic little by little. The Dark City has been ruled by four kings for generations, and no one can cross the line. I still remember that one of the four kings of the past was amazingly talented, and he had already cultivated into a martial saint before he was 100 years old. However, this man was ambitious and unwilling to let the other three kings jointly rule the Dark City, so he killed the other three kings, and that man also fell in that battle. No one knows how these four kings died. There have been at least three such incidents, all of which ended in the same way, so that no one dared to take over the Dark City again, and the people here regarded it as a curse. This curse is the realm of the Dark City. ”

Ou Chuyang listened, his brows furrowed more and more, he didn't believe that these four times were all burned by the four kings, if that was the case, it would be too much of a coincidence. There must be a secret in this.

Staring at Xu Jie'er, Ou Chuyang smiled lightly: "Things are not so simple, right?"

"Of course not. Xu Jie'er wasn't surprised by Ou Chuyang's inquiry, if someone really believed that this was a curse, then this person was really a fool.

Ou Chuyang is not a fool, on the contrary, he is still very shrewd.

Xu Jie'er raised her eyebrows, but her face became solemn: "Actually, these four times, there is only one time, one of the kings was killed by the other three kings, and the conspiracy was not completed." The other three times were the victories of the ambitious man, but after these three great battles, the victorious king was killed. ”

"Killed?" Ou Chuyang was shocked when he heard this.

"Yes. Xu Jie'er nodded heavily, and a cautious color flashed in her eyes: "And it's all just over the war, and it's no more than a day before and after." ”

"Such a coincidence?" Ou Chuyang guessed, and said in his heart: "If so, there should be an invisible force behind this dark city that secretly controls the dark city, so that the dark city can maintain long-term multi-party governance." ”

"I don't need to talk about the rest, I'm sure you can think of it. There is someone in the back of the Dark City. Xu Jie'er looked at Ou Chuyang, who was frowning, and said.

Nodding subconsciously, Ou Chuyang said, "I thought about it, but..."

Ou Chuyang rolled his eyes, raised his head, and asked tentatively: "I believe that with the power of our Jie'er family, I don't know, who is the person behind it?"

"Alas......" This time, Xu Jie'er did not show a profound expression, but shook her head with a touch of regret on her pretty face: "I don't know." There are a lot of secrets on the mainland, and I'm not afraid to tell you, even with my family's strength, there are still a few places that can't be found out in detail, and this dark city is among them. ”

"Huh?" This time it was Ou Chuyang's turn to be surprised, he and Xu Jie'er had been friends for a long time, through the former repeatedly exposing his details, Ou Chuyang had already guessed that his family must be the most powerful existence on this continent, if it was counted, it would be at least stronger than the eight major families. If even Xu Jie'er's family finds out the details of the Dark City, it can only show one problem, that is, the forces behind this Dark City must at least be the same as Xu Jie'er's family.

After thinking about it, Ou Chuyang was about to ask, when a short figure entered Ou Chuyang's line of sight.
