It's not the first time Wind and Fire have come to the world, but it's been a long time since the last time they came. It was when the first king Ouyang Xue Ye first became the lord of the demon world, and he was ordered to go to the human world to investigate several incidents of human beings being attacked by monsters, but he almost had a big fight with a human demon exterminator.

Unexpectedly, it was hundreds of years after he came to the human world again, and he had just heard from Ouyang Hongye that the human administrator of the underground database of Ouyang Ancient Mansion wanted to learn something about Nanzhejiang City and the Nanzhejiang City Lord from him, so he happily went.

He followed Xia Qiu to Ouyang's ancient mansion through the maze path, and was invited to the living room to wait for a while. While waiting for Dong Muya to come up from downstairs, he looked around the living room, there were a few square-shaped things that he had never seen before, and he guessed that they might be the things called electrical appliances that Ouyang Hongye and Mochizuki had mentioned.

After a while, Dong Muya followed Xia Qiu in, this was the first time she and Fenghuo met. Finally being able to see the legendary big monster leopard demon Fenghuo, which made her nervous and excited, and she even became incoherent.

"Hello! I...... I'm Dong Muya, the manager of Ouyang Ancient Mansion, oh no, the manager of Ouyang Ancient Mansion's underground database. ”

She stretched out a hand to Fenghuo, and then looked at the prince of the demon realm in front of her. Sure enough, as Ouyang Hongye had told her, although Fenghuo was not tall, he had a sturdy figure, his eyes were blazing, and his blonde hair mixed with black spots was very conspicuous.

Fenghuo was a little embarrassed and casually shook Dong Muya's outstretched hand and said, "You're welcome, just say hello if you have anything!" ”

Xia Qiu made a pot of Mufu for the two, then handed them a cup and filled it, and sat quietly in the corner.

"Thanks, little girl!" Wind and Fire smiled at her.

Dong Muya took a deep breath and began to enter the topic, asking: "I came to you today to ask if there is anything related to tungsten metal in your impression?" ”

"Tungsten?" Fenghuo didn't understand it very well.

"Tungsten is a metal with an extremely high melting point, and tungsten in the demon world may have a higher melting point than in the human world." Dong Muya added.

"Let me think about it."

Fenghuo felt that the name of that thing was on his lips, but he couldn't remember anything. Such a scene suddenly appeared in his mind, when he was still young, he came to Nanzhejiang for the first time with his father-in-law, Lion Wang Cheng, and it was also at that time that he met the lord of Nanzhejiang City, Huo Guan, who belonged to the same leopard demon clan as himself.

He still remembered that he rode a demon horse and followed behind the lion king Cheng, through the avenue paved with bricks embedded with gold wire patterns, until he came to the front of the Nanzhejiang Palace. At that time, it was Huo Guan himself who stood in front of the palace gate to greet them, and although it was spring, he was still wearing a heavy animal skin robe. It was the first time Feng Huo saw a man wearing so much jewelry, the huge blue diamond on the pure gold necklace was said to be a treasure that was difficult to find in the Three Realms, and any of the colorful gemstone belts that were faintly revealed in the front robe should be priceless.

After a while of greetings between Huo Guan and Lion King Cheng, he stretched out his strong and powerful hand and rubbed it on Feng Huo's head, and asked, "Is that him, the young man who belongs to the same leopard demon royal clan as me?" ”

Wind and fire were rubbed by him, and at the end he slapped him on the face a few times, and he remembered that when his hand crossed his face, something reflected a dazzling light in the sun, which made him squint.

"The Ring of the Northern Underworld!" Wind and fire blurted out.

That's right, it's the ring that Fire Chiena has always worn on her hand. The ring was made from the scale armor of a mythical beast called Pixiu that lived in the sea hundreds of thousands of years ago, and the ring was named because the sea where the beast once lived was called the North Underworld.

Pixiu used to dominate the party, he only ate gold, silver and jewelry, and never went in or out. Legend has it that this ring made of scales on its body also has the magic power to collect wealth, and whoever owns it can get unlimited wealth, and the fire hyena must have believed in this, so he wore it on his hand day and night.

"Where's that ring?" Dong Muya asked.

"It should still be on the corpse of the city lord of Nanzhejiang, unless it was taken by someone who entered the city later."

Feng Huo couldn't be more sure in his heart, for Huo Guan, it was something more important than life, and even at the moment of his death, he would never give him to anyone else. There were very few people he had respected in his life, and he respected Elder Cheng because of his majesty; He respected the former king Ouyang Xueye because of his generosity and kindness; And his respect for the fire hyena may be purely a kind of admiration for his overriding spirit, when he stands in his treasure cabinet, it is like having the whole world, and how could he have thought that his whole world will finally lead him to a road of no return.

The first target was locked on the Northern Ring of the Underworld, but it was still unknown how to convince the Second Elder Lion Wang Cheng and the princes to believe their opinion regarding the Array of Strange Arrays. Because the alchemy array diagram has no provenance, and the solution to it depends entirely on the words of the human child Min Entong, and the old diehards in the royal city to explain the networks, hackers, and high-tech instruments of the human world...... It is equivalent to playing the piano to a cow.

When Ouyang Xiaoleng and Ouyang Hongye were undecided, Fenghuo took the initiative to come to the Yuheng Palace, he had never liked to beat around the bush, and when he saw the Lord of the Demon Realm, he also made a simple salute, and began to express his thoughts.

"Although I'm not very smart, I guess that it is definitely not that simple for you to ask me to answer the matter about Nanzhejiang City and Nanzhejiang City Lord. The city lord of Nanzhejiang has been dead for so long, and you don't seem to believe that the Northern Ring really has any ability to collect money, if you still trust me, just tell me directly, lest I guess and think, uncertain, and impetuous! ”

"We intercepted a map in Qingyun's lair in the Red Mir of Fire City before, and after the analysis of the administrator of the Ouyang Ancient Mansion database you just met, it was an alchemy array map, called the Array of Strange Columns." Ouyang Xiaoleng said.

He felt that instead of explaining the cause and effect of the matter in too much detail, it was better to briefly explain it in an easy-to-understand way, and Ouyang Hongye and his thoughts were the same as his thoughts on this point.

"Wait a minute, Alchemy Array Diagram? Can it be used to make gold? Is the main fire of Nanzhejiang City related to this picture? "Fenghuo still doesn't understand.

"Exactly, but it can be made into something other than gold." Ouyang Hongye explained.

Feng Huo seemed to be enlightened after hearing this, and asked: "Yes, yes, yes, I once heard Huo Guan talk about it, and you can still conjure up the kind of elixir that can live forever, isn't it?" ”

"Yes, just a very small array can conjure these, but if you expand this array, maybe something more powerful will be produced!"

Ouyang Hongye's way of speaking was obviously more understandable to Fenghuo, seeing that he nodded again and again, he continued: "If you want to conjure something, you have to exchange it for equivalent substances, all substances can't be obtained out of thin air, and the same is true for this strange array, it needs to put five substances in five places in the demon world to exchange. ”

"What exactly does Qingyun want to do?" Hearing Ouyang Hongye say this, Fenghuo was a little scared.

"We don't know much about this, we only know the five cities that this array needs, and now we have a rough idea of the transformation material left behind in one of them!" Ouyang Xiaoleng continued.

"Could it be ......" Fenghuo also has a feeling.

"That's right, one of the cities is Nanzhejiang, which has the name of the Golden City, and the transformation material needed in that city is likely to be the Northern Hell Ring worn by the city lord of Nanzhejiang before his death."

Listening to Ouyang Xiaoleng's words, Fenghuo nodded stunned at first, and then began to shake his head desperately. If it was really as they said, Qingyun successfully activated that strange array, then it would definitely bring a huge disaster to the demon world.

Thinking so, he took the initiative to ask for help in a hurry, and said: "No one is more familiar with Nanzhejiang than me, and I will take my own team of subordinates to go." Even if you turn Nanzhejiang upside down, you will have to get the ring of the Northern Underworld back! ”

"But Elder Cheng's side......" Ouyang Hongye stopped talking again.

"Brother, don't worry, my father-in-law will explain it! Then I'll take my leave, go back and sort it out, and set off immediately! ”

Fenghuo nodded to Ouyang Xiaoleng and Ouyang Hongye respectively, and then turned to leave.

"It's really hot, people are as good as their name suggests!" Ouyang Hongye looked at his back, shook his head and sighed.

After solving the first question, Dong Muya immediately began to study the elements of Mucheng Xizhen. When it comes to gloomy wood, it will be reminiscent of coffins, because of the particularity of the material in gloomy wood, even after the baptism of ten thousand years, it will not decay and deform, so it is the best material for making coffins.

And when it comes to coffins, you will inevitably think of the tomb, the demon is not like a human being, except for the noble monster, the ordinary identity will not be put into the coffin after death, so think that the tomb that can appear in Xizhen, must belong to a certain big monster with a more prominent identity.

Dong Muya opened the records about Xizhen, and it was difficult to investigate the prominent monsters who lived there, and it was not difficult to say that it was not difficult. Because Mucheng has only had one city lord in total since the establishment of the city, Blue Snake Xizhen, and this city lord has never liked to have foreign demons stay in her city for too long, and three days is the limit according to her regulations, so the identity of the residents in the city is very simple, and it is easier to investigate.

But also because of the mystery of the city lord Blue Snake Xizhen, there are very few records there, and she rummaged through and found only strong evidence of the existence of a tomb, and the owner of this tomb is the Blue Snake Xizhen. She had the same idea as many emperors in the world, that is, she began to prepare for her death while she was still alive. She had built herself a huge tomb beneath the palace of the wooden city, which was connected to the towering white oak tree in the center of the city before she turned into a demon.

The tomb is a small city, somewhat like a miniature version of the Akamere Dungeon, but without the impetuosity and hustle and bustle of the city. There, everything is white, with white rocks as the roof, white sand as the ground, white wood as the walls, pure white exotic plants reaching to the top of the cave, and the most peculiar thing is the milky white river flowing in the tomb. And Xi Zhen's coffin is in the deepest part of the cave, Dong Muya guessed whether it was because of the snake's habit of living in the cave that she chose the catacombs to become her final sleeping place.

Assuming that this second element, the gloomy wood, really came from the cemetery that belonged to the Blue Snake Xizhen, then it proves that she is likely to die soon. Such a beautiful and quiet monster, I don't know how long it took to cultivate to have a dragon-like body, and it couldn't escape the end of death, what could be the reason?

This is a difficult question that Dong Muya cannot answer, although she knows that the life of demons is much longer than that of humans, their death is sometimes more without warning than that of humans, and often after a long time, they pass away quietly.

In the blink of an eye, she had a general direction on the materials that belonged to the two cities to be arrayed, and was thinking about why there was no news from Min Entong's side, but her phone suddenly rang.

There were only a few words on the mobile phone screen, and she picked it up suspiciously, and said "Hey".

An immature voice sounded: "How is the investigation of the two substances of Jincheng and Mucheng going?" I have already tested specific results for three other substances here, and I will email you now. ”

"Wait, are you Euntong?" Dong Muya was curious that such a young child had a mobile phone, but after thinking about it, it was not surprising for a genius child like him.

"The model of the mobile phone I use should be much more advanced than yours, and I have modified it myself, and the operating system in the mobile phone is also improved by me." Min Entong's voice on the other side sounded calm, but it was obviously like a child's show-off.

Dong Muya couldn't help but laugh for a while, before saying: "Okay, I already have a general direction for those two substances, and the demon world has also sent people to Jincheng Nanzhejiang to investigate, it is said that the Northern Hell Ring, which the city lord Huo Guan's favorite wear before his death, is made of a metal substance similar to tungsten." ”

"Where's Wood City?"

"The catacombs of the Blue Snake Xizhen are probably the place we are looking for!"
