Those things that happened in Luoyun City, although Lin Xiao was not present, he also knew it clearly, the danger of the war of annihilation in advance was gone, but it was a stabbing god, and he became a street rat again, and many of the territories they infiltrated and occupied were given up again, which can be described as a heavy loss.

Before and after Yun Shaoyang left, the joint business of the Heavenly Saint Sect and the Danyang Sect had already set off for the Qi Kingdom, a total of forty people left by flying boat, the goods were carried by large storage tools, and the personnel were mainly used for security, and the Heavenly Saint Sect was led by Bai Zichen and Li Mingyang, two Purple Mansion monks.

At the same time, Lin Xiao had already informed Zhang Mingtang that from now on, he would no longer increase the share of Qianling Liquor to the merchants of the Four Seas, and all the increased production would be sold by himself, and his share would be gradually reduced.

The Four Seas Merchant is very dishonest, making small moves everywhere, Lin Xiao is ready to sanction them with economic means, and now the Four Seas Merchant earns seven or eight hundred thousand Xuanjing a year, most of which is earned by acting as an agent for Qianling Wine, and the rope of Qianling Wine is put around their necks, pull it, let them know who is their food and clothing parents.

At this time, the output of Qianling Liquor is still restricted by Lingshui, and the output of one million copies of Qianling Liquor a year is really only five hundred tons, which is very low, Lin Xiao remembers that in the previous life, a famous wine known as the national liquor had an output of tens of thousands of tons a year, and the output of Qianling Liquor was very different from him.

And there are already six spiritual mountains where the Heavenly Saint Sect planted spiritual fruit trees, and there are hundreds of thousands of spiritual fruits produced every year, and only about two-thirds of them are used to make wine, and the rest are all consumed due to the lack of spiritual water.

However, the development of spiritual water in the Heavenly Saint Sect has also reached the extreme, and the seven spiritual springs that produce spiritual water are all used to brew Qianling Wine, and even Bai Chenxi has to find another way to refine the pill, Danyang Sect, Tianhaimen, and Hongshanmen will also sell about seven or eight thousand catties of spiritual water to the Heavenly Saint Sect every year, but it is still not enough.

In addition to the production of spiritual water, there is also quality, the quality of spiritual water depends on the spiritual spring, and the spiritual spring depends on the spiritual vein, the highest spiritual vein in Tianyun Prefecture is the mountain gate of Danyang Sect, the third order of the upper grade, so it is difficult for the Heavenly Saint Sect to get the spiritual water above the fourth order.

According to the news, the spiritual water used in the existing high-end spirit wine in the immortal cultivation world is basically not lower than the fourth order, and only the spiritual water above the fourth order can ensure the Xuan Qi content of the spirit wine.

But in fact, the price of fourth-order spiritual water is already very expensive, and the amount of use is extremely high, basically the fourth-order spiritual elixir above the fourth order needs to use the fourth-order spiritual water, so the price is as high as the high price of a pound of fourth-order spiritual water and 300 Xuanjing, and it cannot be purchased in large quantities, and people don't sell it at all.

Therefore, Lin Xiao had no choice but to seek to cultivate his own spiritual vein, at this time, after decades of cultivation, the spiritual veins of the Heavenly Saint Sect Mountain Gate had reached the third-order mid-grade level, and the Bailing Mountain side was about to restore the third-order level, and Qiyun Mountain, Baiwu Mountain, and Gongmingfang City were at the second-order upper grade level.

This time, Lin Xiao explained to Bai Zichen and Li Mingyang, after going to Qi to trade, he wanted to collect some treasures to improve his spiritual veins and come back, even if he lost money, he didn't care, relying solely on Xuanjing Yunyu was too slow, and it would take decades for the second-order upper grade to be promoted to the third-order lower grade, Lin Xiao didn't have this patience.

After several years of painstaking cultivation, coupled with the level of the formation mage that Lin Xiao exchanged from the system, Zhou Huaiying, the formation mage of the Heavenly Saint Sect, finally broke through the level of the third-order formation mage, and the protection ability of the Heavenly Saint Sect was improved again, and there was no need for Lin Xiao to systematically change the third-order formation, and he had the ability to independently refine the third-order formation.

In the following months, Zhou Huaiying successively refined many sets of third-order formations, and after the refining ability was greatly improved, Lin Xiao began the plan to build a city in Gongmingfang City.

This plan was mentioned a few years ago, and the Heavenly Saint Sect has also accumulated a large number of building materials for this purpose, these materials are not ordinary bricks and stones, they are all materials that can be used to refine low-level magic weapons, although the price is low, but if the quantity is large, the price will be high.

"This is a common recipe for building materials in the world of cultivating immortals, the foundation is made of second-order basilica stone, strip-shaped, each piece is two meters long, half a meter wide, and half a meter high, to build a small city three miles long and one mile wide, it will cost nearly 20,000 pieces of this kind of bascular, and the market price of a basmine stone is one hundred Xuanjing, even if it is cheaper for large-scale procurement, it will cost 1.5 or 600 million Xuanjing if it is not artificial.

The bricks of the city wall also have to be specially refined, with Xuanying stone, Gangsha, Mingjing mud, and Xuanjing shell according to the proportion of refining, its hardness is harder than the first-order high-grade Xuaniron, if the city wall is more than two meters wide, even if it does not use the formation, it is difficult for Daogang monks to break through.

Now the entire Lu Kingdom, that is, Yujing City, is a city of cultivating immortals to this extent, Tianluo City is the inner city, and the outer city is just an ordinary city wall.

I've seen some records of major events in the world of cultivating immortals, and the cities of cultivating immortals are rarely breached by breaking the city walls, basically relying on internal responses, or the defenders have no intention of fighting, and even weaker city gates. ”

"I see, it means that if we build a city of cultivating immortals according to this standard, as long as we have more than a thousand people to defend it, the other party will not be able to break it with one or two thousand people, right?"

"Theoretically, unless our strength is extremely weak, and the opponent has more than seven or eight Daogang monks attacking continuously, it will be extremely difficult to break through."

"According to the construction standard of three miles long and one mile wide, what is the approximate estimate and how long is the construction time?"

"Not counting the formation, not counting the artificial, at least about three million Xuanjing, the artificial formation is counted, it will not be less than four million Xuanjing, the time depends on the speed of raising materials, if all the materials are all together, and the manpower is enough, two to three years will be fine.

Master, in fact, I don't approve of building this city, the existing Fang City is enough, and the price of three million Xuanjing is too expensive."

"No, you still have to build the city, this city is very important, once it is built, it can be at an angle with the mountain gate, if one day the army is coming, he must divide his troops to surround the city, now five thousand people can surround the mountain gate, at least ten thousand people in the future, otherwise it will be in danger of being attacked on its back"

Lin Xiao shook his head, from an economic point of view, with the current financial resources of the Heavenly Saint Sect, it is not suitable for building a city, but from the point of safety, it will be worth it, Lin Xiao will not stay in Tianyun Prefecture all the time, he will definitely have to travel to the Central Continent of Qi in the future, as soon as he leaves, the safety of the mountain gate must be guaranteed.

"Now that the head has decided, then we can start, and we don't need to rush to build it in two or three years, if the time is extended to less than twenty years, then our pressure will be much looser."

"I understand, that's it, you find some people to come, first plan the place, and then dig the foundation, where you can use mortals, you can use mortals, so as to save some money"

"Yes, Master"

Soon, Lin Xiao ordered the transfer of 10,000 mortals to excavate the planned places around Gongmingfang City, and the huge resources of the Heavenly Saint Sect also began to be mobilized, and all kinds of materials were prepared quickly, and various businesses and merchants from all over the world began to continuously transport various materials to Fang City.

And the generosity of the Heavenly Saint Sect also shocked many people, to build such a city of cultivating immortals, even the Danyang Sect does not have this skill, millions of Xuanjing is not a small amount, very few sects can get this money, besides, it is not good to have this money to cultivate a little more disciples?

Some people even dissuaded Lin Xiao from being so wasteful, isn't the current Gongmingfang City very good, with an annual income of two or three hundred thousand, and the population who has lived in Fang City for a long time has also fallen into a bottleneck stage, and it is mostly a waste to build a Xiuxian City.

But Lin Xiao didn't care so much, they still insisted on going their own way, they didn't understand Lin Xiao's strategy at all, and they couldn't say anything more, so let them misunderstand.

Two months later, the pit of the foundation has been dug up, and the stone of the Xuanjing Stone is also ready, and the next project is not suitable for outsiders to interfere, for fear of being made some secret doors and the like, all of which are completed by the disciples of the Heavenly Saint Sect themselves, so Lin Xiao took out five hundred low-level disciples who cultivated to the fifth to ninth layers of the Kaimai as an engineering team.

The stones weigh thousands of catties, and it is very hard for mortals to put down such stones, but for immortal cultivators, it is not very difficult, because immortal cultivators have mana, and in a month, the stones will become the foundation.

However, this is only the roughest work, because it is not enough to have a foundation, and it is necessary to engrave the formation, and to prevent some martial arts such as the earth escape from entering and leaving the city freely, so the four corners of the city wall have already laid a pillar up to 100 meters long, called the Zhenlong Pillar.

With the Zhenlong Pillar as the support to connect the spiritual veins in Fang City, and then engrave the formation from the stones to protect the underground range of the city, Zhou Huaiying and Xu Zhongsheng and other more than 20 formation mages have to be busy for at least half a year, these more than 20 formation mages have been all accumulated by the Heavenly Sage Sect, although they can recruit formation mages from the outside, but Lin Xiao refused, this is the core part of the city, and it must not be faked.

And when they were busy, Lin Xiao gave part of the city bricks to the loose cultivators in the market, as long as those city bricks were refined according to the proportions, they were extremely simple, and they were not magic weapons at all, even ordinary immortal cultivators could learn them in a few days, and these would not bother the disciples of the Heavenly Saint Sect.

Lin Xiao just sent someone to teach those loose cultivators how to make them, and then buy them at the price they said, of course, someone must supervise them when they buy, so as to prevent someone from being shoddy.

This made the thousands of low-level casual cultivators in Gongmingfang City have a new source of wealth after planting spiritual fields and hunting demon beasts, and in just one month, the scattered cultivators in the fang market have increased a lot, and their arrival has also accelerated the prosperity of the fang market, and after careful calculation, it is much cheaper than refining it yourself.

In Lin Xiao's plan to build the city, the city wall should be six meters high, eight meters wide at the bottom, and about three meters wide at the top.

Lin Xiao dispatched a lot of manpower to protect the construction, and he went to greet Bai Zichen and Li Mingyang, who came back from Qi State, and carefully inquired about Bai Ziyu's affairs in Qi State.
