Compared with the human world, the history of the demon world is even older, and there are many big cities with hundreds of thousands of years of history. However, the giant city made of purple rocks in front of him was not built by demons, but a neutral city built by the Xijia people, called the City of the Two Realms.

Dongsheng Shenzhou is roughly divided into six parts: Middle Earth, East China Sea, Xijia, North Wind, North Dust, and South Demon.

Middle-earth was the territory of the Houtu Dynasty, where human beings lived on the soil and engaged in farming, and were the most powerful. In fact, the so-called Middle-earth is not in the middle, but they occupy the anointed land in the southeast of the continent, and they think they are in the middle of the world, so they call themselves Middle-earth.

There are countless islands, large and small, in the East China Sea, which are occupied by the Aquarium monks. These aquarists are collectively known as sea devils by the Terrans.

Although Beifeng and Beichen are also humans, they are nomadic tribes, living by domesticating aliens, living in the northern desert, which is very different from the Tu people in Middle-earth.

The Sija are also human, but they do not look the same as the people of Middle-earth. Compared with the Tu people, the Sija people have a high nose, deep-set eye sockets, brown and curly hair, and a tall skeleton.

These people are not engaged in farming, but they are good at trading with flying magic weapons, accumulating countless wealth, and also practicing the Xuanmen Dao.

On the west coast of Dongsheng Shenzhou, there is a giant city called Xijia, which is the birthplace of the Xijia people. Xijia is not much better than Houtu City, the capital of the Houtu Dynasty. There is a teleportation array there that can go directly to Beiju Luzhou, and it is the only way to leave Dongsheng Divine Continent.

Between Xijia City and Middle-earth, there is a Hengyun Ridge that stretches for thousands of miles. There are countless mountains and mountains, and there is snow all year round, making it impassable. Therefore, the people of Middle-earth seldom went to the city of Sija. However, Sija's caravan had a huge magic boat, and it was not hindered to pass.

Although the enmity between the two worlds of the human and demon in Dongsheng Divine Continent is as deep as the sea, both sides have a welcoming attitude towards the Xijia people who only recognize money. Therefore the Sijaites built neutral cities everywhere. The Two Realms City not far from the border of the two worlds of demons is one of them.

The City of the Two Realms is one of the key cities for the Xijia people to collect the products of the demon world and the human world, and to transport and trade, and there are all kinds of rare treasures. It is precisely because of this that Lian Ling chose to open up a cave mansion only a hundred miles away from the Two Realms City, just a distance that a large teleportation talisman can travel to. It is precisely to facilitate the acquisition of the four foreign medicines needed for the Gou Dan.

These four major external medicines are Demon Spirit Ginseng, Blood Spirit Stone, Barrier Breaking Pill and Dan Seed.

As far as Gou Zhu is concerned, the Blood Spirit Stone is already ready-made. Even if there are not enough of them, it is not difficult to find more. Comparatively, Dan species are much rarer. But Lian Ling had already prepared a ready-made one for him, and he only needed to go to the Two Realms City to take it out.

The place where the Two Realms City is located is called Ziying Mountain, and the rocks of the mountain have a unique purple color. The whole city was carved in the mountains, surrounded by high walls and forbidden walls, and it was forbidden to fly in the city. But whether it is a human or a demon, as long as it has a human form, whether it is perfect or not, and can afford to enter the city with a penny of blood spirit stones, you can enter the city.

After Gou Zhu cultivated to the peak of the Nine Folds of Foundation Building, half of the original one hundred taels of blood spirit stones had been consumed. But there are still more than fifty taels. Although it was heartbreaking to pay a penny, he was still willing to think of the benefits after entering the city.

"May I ask this old brother, where is the location of the Broken Treasure House?" handed over a penny of blood spirit stones to the guards who entered the city, and asked a little bit of news by the way, how much can be earned.

"First time here?" the warden glanced coldly in one direction, "the tallest building is." ”

The Broken Treasure House is a famous treasure hiding place for the Sija people. There are countless numbered space magic weapons in the treasure house, just like the immortal lotus commonly used by monks. For a storage fee, you can keep the items in the treasure house, or you can mortgage the treasure house for money, or sell it directly to the treasure house.

The item that Gou Zhu was going to cut off from the treasure house was a Dan seed. This Dan seed came at a good time. Thirty years ago, Lian Ling became the palace master of the Jade Palace, cleaned up the remnants of the previous palace masters, and accidentally found a magic key. There was a wisp of Qin Zunyang's divine thought on it, saying:

"Traveling through the demon world, I occasionally got a Dan seed, a masterpiece. It's useless to keep it, and it's a pity to throw it away. It existed in the city of the two realms for 500 years. If you are reincarnated, you can use it. ”

Qin Zunyang was about to soar at that time, but a pill seed that could only be used for foundation building monks and knotting Dan was still in his mind, and he still wanted to reincarnate and rebuild and use it himself, which was worthy of being a famous miser who was greedy for money.

It is not cheap to preserve it for 500 years in the Broken Treasure House. But for Qin Zunyang, it must not be comparable to the value of this Dan seed. It's just that the reincarnation is vast, does he really have a chance to get it back and use it?

Thinking of this, Lian Lingwan smiled. Five hundred years have expired, and this magic key has dimmed, and it is estimated that it will not last long. Since she was going to the demon world this time, she also used it for her disciples by the way. Regardless of him, Qin Zunyang will be so anxious in the Heavenly Realm that he jumps to his feet?

Qin Zunyang was ascended more than five hundred years ago, and he preserved this Dan seed at least ten years before ascending. Therefore, the preservation of this object has long since expired.

However, the rule of severing the treasure house is that as long as the key is not invalid, it can be withdrawn. It is nothing more than the need to pay a storage fee when extracting the product. It's just that once the key fails, there is nothing you can do to break off the treasure house.

Although the spirit of this magic key is dim, it will not be a problem to survive for a few more months. Therefore, Gou Zhu was not in a hurry, and went to the Broken Treasure House safely.

The building that is separated from the treasure house is boxy, like a giant monument, it is thirty zhang high, dozens of floors, like a beehive, densely covered with windows.

The architecture of the Middle-earth people pays attention to the pavilions and pavilions, and the courtyards are deep. The Sijas, on the other hand, have no taste, and are all about building more rooms on a limited plot. All the houses are densely packed and tall squares, like a forest of steles, and the floors are extremely high. There are dozens of floors at every turn, and there is no beauty at all.

This is also similar to the habits of the Sija people. They only look at the amount of money and the amount of money, and they never care what elegance is.

What Gou Zhu didn't know was that on the top floor of this building, in a room decorated with golden light, a handsome young man with pure white hair, a face like jade, and a red vertical stripe between his eyebrows was sitting in a guest seat, playing with a red and blue gem in his hand.

"Father, this Dan seed has obvious resonance with me, and it should have been mine!"

This young man's status is not low, he is the young patriarch of the Ziying tribe of the three-eyed egret clan, named Lu Hao. And the white-haired elder beside him was Lu Baiyu, the patriarch of the prestigious Ziying tribe and the city lord of the Two Realms City.

Although the Ziying tribe is a demon tribe, they took refuge in the Xijia people early and contributed all the land of their tribe to the Xijia people to build a city, so they have received great support from the Xijia people, and the patriarch has always served as the city lord of the Two Realms City.

The Sija people are not xenophobic. Any race that pays enough value to join the Sijahs can find a place in their vast merchant kingdom, and is treated no differently from "their own people".

The boy looked human, but he was holding the right hand of the two-color Dan seed, and his arm was black and covered in phosphoskin. The palms are yellow, slender like branches, and very much like chicken feet. The left hand, on the other hand, is a slender human hand.

Clan demons are different from wild demons. Most of the elders of the clan demons are shapeshifters with perfect human bodies, so they are born with human form, but this human form is not perfect. Some of the demons are ugly and weird, while others have the remains of beast bodies. The boy's left right paw was one of them.

The more perfect the human form of the clan demon, the higher the talent for cultivation. This young man Lu Hao is extremely handsome, almost comparable to the Yao people of Middle-earth. Therefore, he is quite loved by his father Lu Baiyu.

Now that Lu Hao's cultivation is approaching the ninefold consummation of foundation building, Lu Baiyu took him to all the major businesses just to find a suitable Dan seed.

The wild demons in this world have been infected by the aura of heaven and earth for a long time and produce beast cores on their own. It is almost impossible for clan demons and human beings to cultivate. Whether it is a clan demon or a human cultivator, they all live in the mundane world, and the purity of heaven and earth is disturbed by mundane things, and it is extremely difficult to form a pill on their own, so they must rely on foreign "Dan seeds".

The Dan Seed is similar to the beast core naturally produced in the body of the wild demon due to the aura of heaven and earth, except that this "core" is not produced in the body of sentient beings, but in ruthless minerals. Whether it is a human cultivation or a demon cultivation, as long as you use this kind of mineral pill that is self-generated in heaven and earth, you can avoid the disadvantage of not being able to generate a self-generated condensation nucleus, resulting in the inability to form a pill.

It's just that the production of Dan is not easy. Almost all of the Dan species come from the demon realm. And different Dan species have different qualities. The older the Dan species, or the more rare the Dan species, the better the effect of the Dan formation.

"The young master is really sharp-eyed. Behind a red sandalwood table, a Xijia man with a fat face and a bald and shiny shine smiled and complimented, "This Dan is called Yin and Yang Twin Crystals, and it is a masterpiece in the world. The old man has collected treasures for so many years, and he has only seen this one. The only special thing about this Dan species is that there is a certain probability that it can be condensed into a Yin and Yang Double Dan!"

Lu Hao's eyes moved, and he obviously shot a fiery color. Although he hadn't heard of what the Yin and Yang Double Pill was, as far as he knew, the Void Pill cultivators, whether they were human cultivators or demon cultivators, only had one Void Pill. If this pill can actually help people form a double pill, this benefit is simply beyond the imagination of a fool.

The old and spicy Lu Baiyu didn't move much, but just said coldly: "I have also heard some of the fame of the Yin and Yang Twin Crystals. But when it comes to dogs, I don't have more than this choice. The shopkeeper doesn't have to sell anything, just set a price, and I will weigh it. ”

Shopkeeper Sai's eyes rolled, and he quickly made a judgment in his mind, and then stretched out five fingers and said, "Lord of the City, how dare I deceive in any way." Five thousand taels of blood spirit stones, there is no two prices. ”

Five thousand taels of blood spirit stones are equivalent to five million pure yang pills in the human world. You must know that such a large sect in the Jade Palace has an annual income of only 10 million Pure Yang Pills. The Two Realms City is a giant city of merchants, and the income is of course much more than that of the Jade Palace, but these five thousand taels of blood spirit stones are definitely not a small amount of money.

The problem is that this thing has a price, so the shopkeeper opened his mouth casually. When he opened his mouth to set the price, he didn't consider the true value of this Dan species, but Lu Baiyu's tolerance limit.

Unexpectedly, Lu Baiyu didn't think about it, so he threw out an immortal lotus and said, "Five thousand taels of blood spirit stones are in the immortal lotus, let's count them." Then he glanced at Lu Hao, who was playing with the yin and yang twin crystals, "Put away your things and get ready to go." ”

Unexpectedly, the smiling shopkeeper changed his face, and hurriedly stretched out his hand to stop it, and said to Lu Baiyu with a slightly embarrassed face: "There is no doubt that this thing belongs to Young Master Lu, but the city lord can't take it away for the time being!"
