Dai Zhixin's plan was very detailed. But because it was so detailed, many people felt overwhelmed after reading it.

Even Bai Shuanghua, who had been trained by Feng Shao as the successor to the city lord, couldn't help but feel a headache after seeing this.

But Bai Shuanghua also knew that if this plan was well done, it might really allow Wuling City's strength to reach a new level.

After some discussion, Feng Shao finally made the decision: to proceed according to Dai Zhixin's plan.

After the meeting, Dai Zhixin did not leave with Bai Shuanghua immediately, but found Feng Shao privately and said, "City Lord, there is another thing I want to tell you."

Feng Shao asked curiously, "What's the matter?"

Dai Zhixin first handed Feng Shao a blueprint, and then smiled and said, "It's about the cultivation of spirit stones."

"Spirit Stone Cultivation?" Feng Shao was stunned. I know about spirit stones, and I know about cultivation, but what the hell is spirit stone cultivation?

Feng Shao looked down at the drawing in his hand and found that it was a box with multiple pipes and air holes. Judging from the specifications, it looked a bit like a steamer. But a steamer wouldn't require a special drawing, right?

Dai Zhixin saw Feng Shao's puzzled look, and she felt even more proud. She couldn't help but laugh secretly: You didn't expect it? I just took out your future design in advance!

But Dai Zhixin said calmly, "This is a spirit stone cultivation device that can be used to cultivate spirit stones. Each box can cultivate 100 spirit stones at the same time. Each box is about half a foot high. If it is stacked in a space of ten feet high, it can be stacked in 20 layers, which means 2,000 spirit stones. According to my estimation, a space of 400 square meters can hold 18,000 boxes, which means 1.8 million spirit stones."

Feng Shao quickly raised his hand and said, "Stop! Stop! Tell me first, what exactly is Spirit Stone Cultivation! I have never heard of this term before."

Dai Zhixin smiled and said, "City Lord, do you know how spirit stones are formed?"

Feng Shao frowned: "Isn't this a natural mineral deposit?"

Dai Zhixin shook her head and said, "There are still some errors in your understanding. Spiritual stones are essentially a byproduct of natural spiritual energy."

Afterwards, Dai Zhixin told Feng Shao in detail what she knew.

It turns out that spiritual stone cannot be considered a natural mineral deposit, but a product of long-term immersion in natural spiritual energy.

To put it simply, the natural spiritual energy comes first, and then the spiritual stone comes.

Natural spiritual energy is widely present in this world. The natural spiritual energy mined in Wuling City should actually be considered as the middle-level spiritual energy vein. The spiritual stone is formed by the shallow natural spiritual energy veins about 30 to 100 meters underground.

From more than 100 meters underground to the surface, geological activities are relatively active. From time to time, some deep or middle-layer natural spiritual energy veins will enter the shallow layer under the influence of geological activities. The rock layer where the shallow natural spiritual energy is located has too many cracks, so it generally does not exist for a long time. This natural spiritual energy will gradually dissipate into the surrounding rock layers over time and gradually penetrate into the rock. After absorbing a certain degree of spiritual energy, ordinary rocks will become spiritual stones.

This is the origin of the spiritual stone vein.

In other words, all spiritual stones are essentially formed by long-term absorption of spiritual energy. Before this, they were just ordinary stones.

Hearing this, Feng Shao couldn't help but eyelids jump: "So, you want to artificially create an environment that can allow rocks to absorb spiritual energy in order to cultivate artificial spiritual stones?"

"Bingo! City Lord, you guessed it right!" Dai Zhixin said with a smile, "Since we know the formation principle of spirit stones, why don't we make spirit stones ourselves? Isn't this equivalent to opening a banknote printing factory? And the currency printed is the currency used by the whole world!"

Feng Shao's mouth twitched. If this idea could really be realized, Wuling City would be a real treasure trove!

The spirit stone in this world is a stone with one side spherical and the other side square, which looks a bit like a cupcake and weighs about one tael (50g). It is the common currency circulated mainly in the world of cultivation.

Unlike the real world, the spirit stones in this world are of uniform specifications, and there are no broken spirit stones, so there is no need to add the weight unit "liang" at the end.

(The broken silver in the world today is actually cut from official ingots. Unlike gold, silver is softer and can be cut with ordinary iron scissors. Therefore, broken silver was common in ancient times, but broken gold was rare. In addition, since the weight of broken silver varies, most merchants have to prepare their own special small scales for weighing.)

As a hard currency generally recognized by monks, it can be used not only as currency, but also as a cultivation resource. For example, in some areas where spiritual energy is scarce, monks can directly use spiritual stones to absorb spiritual energy for cultivation. In addition, facilities such as the sect protection array and the spirit gathering tower also require a large amount of spiritual stones.

For a sect, if they could obtain a large spiritual stone vein, it would be like obtaining a gold mine. There were countless sects that had fought over a spiritual stone vein, resulting in countless casualties. The number of sects and forces that were destroyed because of this was even more numerous.

But for a long time, no one knew that spirit stones could be cultivated artificially? !

"Of course, cultivating spirit stones is not an easy task. First of all, it's a matter of material. Most stones are not suitable as carriers of spirit stones. Even if they absorb spiritual energy, it will gradually dissipate. As far as I know, the best material for spirit stones is marble, which is calcium carbonate. Spirit stones made of this material have a stable shape and the spiritual energy is not easily lost.

"So we just need to mine a large amount of marble, cut it into the shape of spiritual stones, and then use the device I drew to cultivate it on a large scale. Within a year, we can harvest a large amount of high-quality spiritual stones!"

Dai Zhixin gestured with her hands as she spoke: "We can dig out a space for cultivating spirit stones directly under Wuling City, and then infuse it with highly concentrated natural spiritual energy and maintain the concentration of spiritual energy. As long as the gaps between the spirit stones are kept the same, the marble can absorb the spiritual energy at the fastest speed. In this way, the cultivation speed of artificial spirit stones will be much faster than that of natural spirit stones."

After the initial surprise, Feng Shao immediately calmed down and began to think carefully.

Although it is not clear where Dai Zhixin got this knowledge from, seeing how confident she is, she must have a basis for it. If it is really possible to cultivate spirit stones on a large scale, it would be a big success. After all, who can resist money?

One cultivation room can cultivate 1.8 million spirit stones a year, and with Wuling City's capabilities, building 10,000 cultivation rooms is no problem, which means an annual income of 18 billion! What does this mean? Yunjian Pavilion has been operating for decades, but has never made so much money!

But after the initial excitement, Feng Shao immediately realized that although this idea was tempting, it was not feasible because he had to consider human greed.

A city without spiritual stone ore veins can easily produce a large number of spiritual stones. Even a fool would think something is wrong. In addition, mining a large amount of marble and making it into the shape of spiritual stones is impossible to do secretly. Therefore, anyone who is interested will definitely be able to detect that Wuling City has the ability to cultivate spiritual stones on a large scale.

This ability is enough to drive all the sects and forces crazy. Once discovered, Wuling City will inevitably become the target of public criticism. Even if Wuling City has Yunjian Pavilion behind it, it is powerless to fight against so many sects and forces!

Therefore, unless Wuling City possesses the strength to dominate the entire Upper Domain, this kind of spirit stone cultivation can only be carried out on a small scale.

In addition, even if he did not consider the greed of human beings, he had to consider the problem of inflation. So many spirit stones entering circulation would be enough to affect the spirit stone market in Dongzhou and even the entire Upper Domain. When spirit stones became less and less valuable, the cultivation world would also be stirred up.

Feng Shao really wanted to make money, but this way of making money must have a bottom line. If it would disrupt order and cause unrest, then it would be better not to use this way of making money.

However, considering Wuling City’s current lack of money, Feng Shao felt that it could still be used on a small scale.

So Feng Shao said: "We need to think about this matter carefully. The people who participate in the cultivation of spirit stones must be absolutely trustworthy. I will find some trustworthy people to hand over to you, and you will lead the work of cultivating spirit stones. According to your plan, develop ten cultivation rooms first. Please note that this matter must not be leaked at all!"

Dai Zhixin also understood the risks of this matter and nodded solemnly: "Don't worry, City Lord, I know the limits."

A few days later, Feng Shao found some steady and capable people from Taiwei Sect and gave them to Dai Zhixin. After all, these disciples were all brought up by him and were people he absolutely trusted.

After Dai Zhixin had enough manpower, she also started the work of cultivating spirit stones. She also knew how much disaster would be caused if the matter of cultivating spirit stones was leaked, so the whole process was done secretly, just like printing counterfeit money. The difference was that she printed real money that could not be used anywhere.

On the other hand, the meeting hall was jointly led by Feng Shao and Bai Shuanghua, who began to carry out new urban construction work in accordance with Dai Zhixin's development plan.

Just when everything was going on in full swing, a guest suddenly appeared in Wuling City. He went straight to the City Lord's Mansion and asked to visit Wuling City Lord Feng Shao.

As soon as Feng Shao saw the other person, he was startled. The other person smiled at Feng Shao and said, "Brother Feng, long time no see!"

Feng Shao nodded: "It's been a long time since we last met. Brother Deng, have you made all the preparations for coming here today?"

The person who came was none other than the Lord of Qianyun City, Deng Jingyun.

(Of the two ideas I mentioned, more people have suggested reading the second one. You can read the book first and give your own opinions. The original book has a total of 250,000 words. I hope you like it.)
