(776 Thousand-year-old Giant City, Wan Jun Ning Yidan)

The next day, when they teleported to Houtu City, it was already night.

As soon as he walked out of the teleportation array of Houtu City, what Gou Zhu saw was a huge bridge erected in the air, and the light bands composed of countless night pearls illuminated them, like bridges of light leading to the heavenly realm.

Outside, there are huge pavilions that are stacked on top of each other. Illuminated flying boats pass between these huge pavilions. On the bridges that connect with each other, all kinds of cars, horses and people flow like a tide.

Compared with the Golden Jade City, the history of Houtu City in Guizhou is much older.

The city was built here thousands of years ago. In order to protect against attacks from the north, all the buildings here were forts in the beginning, and the fortified city was thick-walled, almost all of which were piled up with huge stones from the nearby mountains.

Some are made by man, while others are miracles of the magic power of powerful monks.

Cities have expanded and overlapped throughout the ages. New high-rise buildings were built on top of abandoned fortresses, and the collapsed city was reinforced, rammed and leveled, and then continued to be built.

The whole city is like a living thing, and many huge towers are growing closer and closer to the sky like giant bamboo shoots.

In order to facilitate transportation, they had to build a bridge to connect the huge stone towers to each other, forming a complex forest-like stone city.

If you have the money and don't have to walk hard, you can rent a flying boat. But the traffic in the air is also quite congested.

The entire state of Guizhou is as big as the four states of Jin, Yu, Yi, and Tong combined, and they are all fertile plains. In terms of area, it is just not as desolate as the northwest of the lost state. The population accounted for more than half of the entire Houtu Dynasty.

The population of Guy and other surrounding states is pouring towards Atsuchi, and you can imagine how crowded it is.

Lian Ling didn't show up, she still hid in Gouzhu's neck with her Shuralan body. Everyone else has their own disguises.

After the group got out of the teleportation array, they went directly to the "Easy Club" prepared by the imperial court for the Getaway Club and stayed.

The imperial court also knew the preferences of the monks, so the area where the Xiaoyao Hall was located was the area where the Xuan City was concentrated.

The monks who lived there could walk a short distance at night to the city of Daigen, the city of Atsuto. Nearby neighborhoods are under special alerts, and ordinary mortals are not allowed to enter.

Gou Zhu came out to visit Xuan City on the first night. To keep a low profile, he brought only two people. One is the mortal Song Lan, and the other is the former Soul Sect elder Miao Zhong, who has become a resurrected corpse.

With the treacherous aura of the Yin Dan, the cultivation looks like it is just about the four colors of the Void Dan. Miao Zhong did not hide his cultivation, and others could see the realm of his Purple Mansion Erqi. Song Lan is a mortal.

In Xuan City, a thick earth city that hides Crouching Tigers, this cultivation is very common.

This time, they teleported from Cloud Sky City to Thick Earth City, and they did not deliberately hide their whereabouts. Gou Zhu believed that from the moment they set off from Jade Peak, the people of the Song family had already set their sights on them.

That's exactly what he wanted. He deliberately took Song Lan out, that is, to tell the ancestor of the Song family: "The person you want is in my hands, are you greedy?"

If the ancestor of the Song family couldn't help but make a move on him, this would be even more what he wanted.

He has two Jindan double-flower masters hidden on his body, Lian Ling and Han Beizi. Moreover, this is in Daxuan City, Houtu City, which can be said to be the most rigorous place in the world to guard against monks fighting.

If the ancestor of the Song family is frustrated, he will know even better: trading with Song Ruhai is the only way for him to get involved with Song Lan. Other cleverness is useless. In this way, Song Ruhai and his fishing transaction will also be smoother.

The Xuan City of Houtu City is not like the Xuan Market in Qingyang Town, where the sellers all set up stalls in the cemetery.

Each building here has a high dome, a wide space, and a crystal clear terrazzo marble floor, which is as elegant as a royal palace.

Countless such halls are connected by straight corridors. Standing in the middle of the corridor and looking back and forth, it is as if you are standing in the middle of two mirrors facing each other, and you can see one hall after another converging and disappearing into the infinite distance.

The content of the transactions in each lobby is slightly different. For example, there are those who specialize in trading exotic flowers and plants, those who specialize in trading beast cores, and those who only trade weapons. And Gou Zhu came this time for nothing else, he only looked for the Jindan foreign medicine for the Jindan he was about to condense.

Jindan is probably the hardest and heaviest thing in the world.

If it was placed in the ancient times, the monks would have to refine the mana gathered by the Void Pill bit by bit in the Purple Mansion, and finally turn the void into reality, and it took hundreds of years to finally achieve the Golden Pill.

In modern times, the Xuanmen monks have already discovered the external medicine that can condense the golden pill, so there is no need to be so troublesome.

If the real golden pill can be taken out and placed in the material world, the golden pill the size of the jujube core can reach the weight of tens of thousands of catties.

It's just a pity that this thing can't exist stably. If you move into the present world, it will explode and release a huge amount of energy.

But if you say it through, Jin Dan is actually an ordinary substance condensed by spiritual energy.

It's just that these substances are extremely compressed by the monk's mana, forming a huge density, so that they emit a strong light, and they look almost indistinguishable from the sun, so they are called Jindan.

The monk's purple mansion is a world of its own, which is similar to leaving the world. Jin Dan exists in it, isolated from the present world, so as not to make the weight of each Jin Dan monk skyrocket to tens of thousands of catties.

If the monk dies, the golden pill will soon be annihilated between the Purple Mansion and the heaven and earth of the present world.

Those techniques that can transfer some of the substances in the golden pill to the present world and use them as weapons are rare secret techniques, and normal monks would not use them as suicidal.

There is no problem with the Purple Mansion of Gou, what he needs now is to condense the golden pill.

Jindan external medicine is much simpler than the external medicine of condensing the void pill, and all the Jindan external medicine in the world is the same, and there is only one, called "Tianyin Stone".

Tianyin Stone is essentially the same substance as Jindan, with huge density and incomparably heavy.

As long as this kind of thing is transferred into his own Purple Mansion for refining, it will become the seed of the Golden Pill. The golden pill will grow and take shape on it.

In the present world, each piece of the Heavenly Stone is as fine as dust and needs to be preserved with a special magic weapon. If it is directly exposed to the present world, it will explode and annihilate.

Fortunately, the volume of the Tianyin Stone is generally less than the size of a thousandth of a sesame seed, and the power is not too great.

Such a strange substance is naturally not something that can be found on earth. The Heavenly Stones were all obtained from the heavens by powerful immortals. It is said that among the brilliant stars above the heavenly realm, many of them are composed of celestial stones.

Some people even speculate that when the sun reaches the point of decline, the whole will turn into a planet made of celestial stones.

Unlike Jindan Sanhua external medicine, Tianyin Stone is not uncommon. This thing can be stored for a long time, and each time it achieves Jindan, it only needs to be as fine as a little bit, so there is a lot of stock on the market.

All the monks who have achieved the Purple Mansion will buy a Heavenly Guide Stone for themselves in advance. There are even some monks of the family who have prepared the Heavenly Guiding Stone from the first day they enter the Xuanmen.

But how many people in the world can really use the Heavenly Guiding Stone?

When the Purple Mansion is completed, you can "take" this stone. As for when Jin Dan can be achieved, it depends on personal merit.

Lian Ling had already taken the Tianyin Stone after the consummation of the Purple Mansion, but he waited until he bathed in the root of the immortal tree to truly achieve Jindan.

But Gou Zhu has never taken the Tianyin Stone. The reason is not only that Lian Ling doesn't want his foundation to be unstable, but also that his Void Pill grade is too high.

Such a perfect Void Pill, if you don't use the Perfect Heavenly Primer Stone, it would be a waste.

Most of the really good Heavenly Stones come from Houtu City. The reason for this is very simple, whoever has produced more Ascended Immortals on the ancestors is likely to leave more Heavenly Attraction Stones. And the great families gathered in Houtu City are the most.

Whose ancestors have the most ascended immortals? Naturally, it is the Hao family, the royal family of the Houtu Dynasty. Few of the emperors of the Houtu Dynasty died. The way of death is almost always ascension.

Today, Emperor Kun Yuan Haohan is already the consummation of Jindan Sanhua. It is said that he will soon become a Yuan Baby. Once he attained the primordial infant, he had to fly to the sky. The entire property of the Houtu Dynasty, he will be handed over to his son after all.

The Emperor of Heaven is also surnamed Hao, and the Hao family on earth is just a branch of the Hao family in heaven. Therefore, it is not surprising that they have the best Celestial Stones.

Therefore, Houtu City Daxuan City is the place where Gou Zhu will inevitably come.

He resisted a lot of temptations and came to a hall dedicated to selling foreign medicine for promotion. There are literally all the foreign medicines here. From Xudan to Jindan, there are almost everything except Jindan Sanhua foreign medicine.

(The first time Gou Zhu came to Houtu City, I felt the same way I felt when I first came to Shanghai.) It happened to be evening, when I walked out of the Meilong Town Railway Station, the first thing I saw was a lot of huge viaducts.

The prototype of Houtu City Xuan City is Yiwu Small Commodity Market. What I saw there was a continuous stream of connected buildings, each full of shops. I remember an entire building full of bags and no end in the straight corridors.

Each state's name is derived from a mineral. For example, Jinzhou is gold, Yuzhou is jade, Yizhou is tin, Lost is iron, and Guizhou is silicon. ）
