In fact, Ling Zhenfei had long known that he had revealed this stunt of condensing qi into a needle, and if he met a master of traditional Chinese medicine, it would be easy to see through.

However, even so, he will not hesitate to use his magic skills to save people.

After all, human life is greater than heaven, and it is the duty of a doctor to cure diseases and save people. At that time, the life of the injured was in danger, how could he stand idly by?

After resting for the night, Ling Zhenfei got up early in the morning and walked towards Xishan Farm.

Although he is very comfortable with his current hands-off shopkeeper, even if he doesn't have to do many small things himself, some of the overall situation still needs to be mastered by himself.

For example, the matter of fish farming, he has been thinking about it for a long time.

The construction of the farm has been completed long ago, all the land has been used for growing vegetables, and the pond under the mountain has been renovated into a fish pond, but the fish have not been put in it for the time being.

Originally, according to Ling Zhenfei's plan, he wanted to use this large fish pond for breeding ornamental fish, but after consulting experts in this area, he realized that his idea was very naïve.

After all, most of those ornamental fish are tropical fish, and their small bodies are very expensive, and they must be served by knowledgeable personnel.

The advice given by the experts is to build a greenhouse dedicated to the cultivation of tropical fish, with several large glass fish tanks indoors, and the temperature difference between indoor and outdoor should not be too large.

Ling Zhenfei listened to the advice of the experts, such a greenhouse is also under construction, and although he forced Ikeda Yasushi to provide koi fish fry, the guy's goods have not been used yet, so there is no need to rush for a while.

Ornamental fish are kept in a greenhouse glass tank, but the fish pond in front of the farm is vacant.

Li Ermeng came to Ling Zhenfei several times, and proposed to put some fish fry in the fish pond, anyway, the residual leaves of the vegetable roots picked in the farm every season are also wasted, so they are broken up for feed and used to raise fish, which can be regarded as waste utilization.

Regarding Li Ermeng's proposal, Ling Zhenfei of course agreed. However, I was a little hesitant about what kind of fish to raise.

Li Ermeng's suggestion is to raise some common crucian carp, carp, and grass carp in the market. But Ling Zhenfei thinks that there are too many fish farmers in these fish markets, and people are tired of eating them, and if they go to raise them again, they don't seem to have much competitiveness.

Even if Ling Zhenfei used the water in the Spatial Sacred Spring to breed, although he could ensure the deliciousness of these fish, it was unlikely to have much advantage in terms of price and profit.

After listening to Ling Zhenfei's words, Li Ermeng also felt that it was very reasonable. So, the two of them decided to take advantage of their free time in the morning to go to the aquatic market in the city to see what fish species have large profit margins and are suitable for long-term development.

The plan was decided, and Ling Zhenfei rode an electric tricycle and drove Li Ermeng towards the city.

It was also the first time for both of them to visit the city's fish market, and when they arrived at the location, they were immediately stunned by the spectacular scene in front of them.

Located in the western suburbs of Binyang City, this aquatic product market, can be called the largest aquatic product trading market in the province and city, the whole market is divided into three areas, except for some retail households operating in the periphery of a district, most of them are all large households that do all kinds of aquatic products wholesale.

Looking at the entire market, all kinds of aquatic products in rivers, lakes and seas, which can be called or not, are readily available.

Ling Zhenfei and Li Ermeng walked around the market, and the feeling was like Grandma Liu entering the Grand View Garden, and she was dazzled, and she was not sure what kind of fish fry she wanted to buy to go back to farming.

However, this was difficult for Ling Zhenfei. The so-called scarcity is expensive, and the more fish species appear in the market, it basically means that this is a big road commodity and is not worth farming. He took Li Ermeng around the market, specifically looking for the kind of fish that was in short supply in the market and sold for a lot of money.

The hard work pays off, and there are really such fish species, the most notable of which is the sea bass.

When Ling Zhenfei used to study, he once read "The Fisherman on the River" by Fan Zhongyan, a great writer in the Song Dynasty, and there is a popular verse in the poem: People come and go on the river, but they love the beauty of sea bass.

He himself had eaten sea bass before, and at that time, he didn't know if it was because of the chef's superb skills, or because the taste of sea bass was delicious, Ling Zhenfei still remembered that taste, and he was still very nostalgic.

That's right, just farming sea bass!

The economic value of sea bass is considerable, the meat of sea bass is firm and white, not only has high nutritional value but also tastes delicious.

Raising sea bass is definitely a good business.

What's more, Ling Zhenfei has the Holy Spring Spirit Pot in the space, as long as the water of the Holy Spring is introduced into the fish pond, the taste of the raised sea bass will definitely be a hundred times more delicious than all similar sea bass on the market. In the future, it will be put on the market, and it will definitely be a hot hit!

The more Ling Zhenfei thought about it, the more excited he became, and told Li Ermeng about this idea, and Li Ermeng also agreed with it very much.

So, the two ran to a stall selling sea bass and asked, but they couldn't help but be dumbfounded.

Ling Zhenfei's judgment is indeed correct, sea bass is indeed a scarce fish species in the market, and the price is extremely high. The wholesale price of ordinary freshwater sea bass in the market here alone is 30 to 40 yuan a catty. Of course, if the retail price is sold, it will more than double.

The price of sea bass is so expensive, it should be the preferred species for farmers.

It's just that this fish is a species used for export in China.

What's more, the fry of this fish are currently only caught by the sea, and the success rate of artificial breeding is too low. This is the main reason why it is not very common in the market.

"Xiaofei, it seems that this perch is really not easy to raise, let's change the fish species!"

Hearing the shopkeeper's explanation, Li Ermeng's interest that had just risen was immediately extinguished by cold water, and he had to say to Ling Zhenfei stupidly.

Although he said that the farm was not his, he was serious and responsible, but he didn't want Ling Zhenfei to be poor at nutrition, and it would be bad if he lost money.

"The harder the sea bass is to raise, doesn't that mean the market needs it?"

However, for sea bass farming, Ling Zhenfei is full of confidence. Not only did he not give up, but he patted Li Ermeng's shoulder with confidence and said, "Brother Mengzi, don't worry, I have full confidence in how to raise perch well!"

I have to say that Ling Zhenfei does have such confidence. After all, the space is full of spiritual energy, coupled with the irrigation of the spiritual spring, even the most difficult fish species, he can completely achieve batch farming.

"This ......" Looking at Ling Zhenfei's confident look, Li Ermeng couldn't help but hesitate a little.

Li Ermeng really doesn't understand where Ling Zhenfei comes from such confidence, he grew up with Ling Zhenfei since he was a child, and knows Ling Zhenfei quite well, knowing that he doesn't know anything about breeding at all!

Such a layman, where did he get his confidence?
