I don't understand it, and Li Lin doesn't plan to think about it, anyway, this problem can still be verified by observation later.

Ouyang Yufei sent Li Lin and Wu Yan to the restaurant and went to work. Li Lin looked at Ouyang Yufei who was far away, and thought to himself, I still have to buy a car as soon as possible, otherwise it will always be very convenient for her to send it, but although now, the restaurant is making money every day, but there is really not much money left to buy a car.

Coming to the kitchen, Li Lin put the fish in the fish pond into the fish tank, and left, and then went straight to his small office, and told Wu Yan, there is nothing important, don't let other people disturb him, he doesn't want someone to disturb him when he is studying pearl farming in the system.

Li Lin's consciousness entered the system, and in order to study this river mussel, Li Lin planned to collect a river mussel first, and then pick him up to take a look.

There were not many mature river mussels in the fish pond at this time, Li Lin immediately collected one, and then entered the backpack, ready to take it out for research, but Li Lin, who had just entered the backpack, was stunned, and there were not only 18 more river mussels in the backpack now, but in a square behind it, Li Lin also found the existence of pearls!

Li Lin can be sure that he didn't put the pearls in the backpack before, so now the origin of this extra pearl is obvious, it is from the fish river mussel!

Pearl farming was a success!

Li Lin is overjoyed, the current situation is already very telling, and he doesn't need to study how the mussels in the system produce pearls, it seems that this system is very humane, and the pearl farming will be automatically charged when the mussels are harvested.

Of course, there are also disadvantages, that is, when the mussels are not ripe, whether the pearls are successfully cultivated or not, they cannot be collected, but this small flaw is not a problem at all, because the maturity time of the mussels in this system is very short, and it doesn't matter if this time is too long.

Li Lin was very surprised that pearls could be successfully cultivated in such a short period of time, and he also learned about it before, and it took 3 to 5 years for freshwater cultured pearls to mature, Li Lin knew that in the system, this time would be shortened, but he didn't expect it to be such a short time.

Li Lin looked at the number of these pearls, and there were 362 of them!

Obviously, so many pearls could not have come from a river mussel, and although he had just harvested one river mussel from the system's fish pond, he got 18 of them, that is, all 18 river mussels produced pearls, but in fact they were just one river mussel he had raised.

In other words, he had only raised thousands of mussels before, but in the end he would harvest tens or even hundreds of thousands of pearl-producing mussels. Although this pearl is worthless now, it can't withstand its large volume, and Li Lin also learned that not all freshwater pearls are not before, those pearls with large diameter, perfect round, and bright color are still expensive.

At the same time, Li Lin was also very satisfied with the pearl production rate of this river mussel, and these 18 river mussels harvested 362 pearls, although he didn't have time to look at the size of these pearls, but this number already made him very satisfied.

Li Lin took out a pearl and put it in the palm of his hand, the surface of this pearl was crystal moist, the rainbow color was clear, and there was a cool feeling in the palm of his hand. As for the size, Li Lin estimates that its diameter is about 1cm, and the whole pearl is almost a perfect circle, which is very comfortable to look at.

Although Li Lin didn't know how the price of pearls was set, he understood a simple truth, the brighter, roather, and smoother the surface of the pearl, the more precious it was!

Li Lin then took out another one, one was slightly smaller than the one just now, but it was not much worse, the surface was also smooth, and the shape was also round.

Li Lin slowly took out the pearls in the backpack one by one, and he found that these 362 pearls were all almost perfectly round, and there was not even an irregular one, you know, in reality, artificially cultivated freshwater pearls can only have one or two out of every 100 relatively perfect, but it is almost 100% in his system.

Moreover, these pearls are also smooth in surface, round and delicate in color, and most of them are about 10mm in size, and Li Lin even found a few pearls that are almost about 12mm in these.

However, to Li Lin's slight regret, these pearls are all white, not pink or purple.

"The reason why these pearls are so similar in size and appearance is because they come from the same pearl mussel?" Li Lin pondered.

Li Lin put these pearls into his backpack again, he originally planned to come in to study how to harvest pearls, but he didn't expect that this is the situation now, since the pearls have matured, Li Lin plans to collect them on a large scale.

However, Li Lin later found that not every mature river mussel could harvest pearls, and some river mussels were collected without the slightest shadow of pearls.

"Is it because these mussels are the descendants of the river mussels that have undergone surgery, because they have not had surgery, or because the pearls in these mussels have not been successfully cultivated?" Li Lin looked at the fact that he had harvested several river mussels in a row without pearls, and secretly wondered.

It's just that this question is still hard to say, maybe because I haven't had surgery, but it may also be that it is not mature, which can only be observed slowly in the future. And in order to find out what the reason is, Li Lin plans not to exchange the new river mussels for surgery and put them in, but to collect all the mature river mussels, and put back the ones without pearls, and the river mussels that have received pearls will be temporarily placed in the backpack, anyway, they will occupy a grid, and they will not die.

In the end, after Li Lin collected all the mature river mussels in the fish pond, he got nearly 10,000 pearls. It's just that these pearls are big and small, the shape is perfectly round, and some are nearly round, but the color is very good, and the feel is also very good.

Li Lin looked at the many pearls in the backpack with satisfaction, although not all the pearls collected later were as good as those produced by the first river mussel, but, overall, he already wanted to be good.

As for these pearls, Li Lin had already thought about where they were going. Thinking of this, Li Lin didn't plan to stay here. Anyway, there shouldn't be anything going on in the restaurant, and he came today mainly to supplement the ingredients in the restaurant.

After saying hello to Wu Yan, Li Lin went out to take a taxi and went straight to the Qifu jewelry store in the city center.

Qifu Jewellery is the largest private jewelry store in China, and it has chain stores in almost all first- and second-tier cities in China. The store not only sells a variety of jewelry, but also collects a variety of raw materials.

Soon, Li Lin arrived at his destination, after all, his restaurant is not far from the city center, and the fact that he can have a store of four or five hundred square meters in the downtown area also shows that Qifu Jewelry is different.
