After a while, someone dug up the mussel and screamed to find a knife to pry it open, but there was nothing inside.

Looking at the very small river mussel, Yun Yi felt that it was too small, so the few strands with pearls were relatively small.

After walking not far to the deep water, Yunyi dived carefully at the bottom of the water, and after a while. There was a big mussel, which was about the same as the one just now; Hurriedly pried the mussel open, which immediately disappointed him a little, there was only one pearl in it, and the size was also very small.

"Yunyi, you dug up another pearl!"

The people around looked at Yunyi enviously, the river mussels they dug up did not even have a pearl in it.

"The river mussel has to be big, and the chance of a small river mussel producing pearls is low!"

The biology teacher smiled, and then continued to walk into the deep water like Yunyi, but his water quality was not very good, and he could only dive and grope at a distance of two or three meters.

It was inconvenient to hold the pearl in his hand, and Yun Yi didn't want to waste time back and forth, so he wanted Xiaobai to send the pearl back, but he was worried that this guy would accidentally swallow it in his mouth.

"Xiaobai, you go up and carry Wukong over, boss, I have a task for you!"

patted Xiaobai on the head, Xiaobai swam to the shore very obediently, and shouted at Wukong a few times, and then Wukong rode on Xiaobai's back and came over to Yunyi.

"Ha, Wukong, this is looking for a mount that knows water!"

The monkey riding on the dog surprised many people.

put the pearl in the cloth pocket in front of Wukong, buttoned it and sent Xiaobai to swim to the shore, and then Yunyi continued to find it in the deep water, and kept touching. When I got to a depth of seven or eight meters, I finally touched it again. Arrived at a mussel, and the volume is also very large.

However, because the water depth is more than eight meters, although the water is very good. But it didn't last much under such a high water pressure.

After working for a while, the mussel, which was 25 centimeters in diameter, was dug out of the mud and sand, and then swam to the neck depth, where he pried the mussel open again.

There are also pearls in this river mussel, but there is only one, it is quite large, almost the size of a pea, which makes Yun Yi a little disappointed, it seems that he remembers the river mussels used to cultivate pearls in the past, and there are more than a dozen pearls in it.

"Yunyi found another river mussel with pearls!"

Someone exclaimed. Everyone swam to Yun Yi's side with envy again, looking at his river mussel of more than 20 centimeters, and the pearl in his hand that was more than a soybean with a reward of three points, and they all sighed Yun Yi's luck in their hearts.

"Yunyi, your luck is too good, this time to find a river mussel is so big, you can also dig up pearls, I have dug up three river mussels, but I haven't seen a pearl!"

Long Xiaotian was also quite envious. Although I don't care about the price of pearls, the meaning of being able to dig up pearls and give them to my girlfriend is still different.

"It's just a pearl. What is there to envy, Ya, I remember looking at the kind of pearls in the shopping mall before, there are dozens of mussels in a river mussel, and I only have one in it. It's so decaying! ”

Yun Yi didn't care about the pearls in his hand, obviously very dissatisfied with the small number.

"Hehe, that's artificially cultured pearls. Generally, the larger the mussel, the more pearls are raised; You wild river mussel, the number of pearls depends on luck! ”

The biology teacher said with a smile, so that Yun Yi understood this problem, and he also regretted a little bit of the way he was remembering the way he took the pearls directly from the live mussels, as soon as he scraped it with a knife, the river mussels were dead; If such a large wild mussel is used to cultivate pearls, there can be as many as thirty or forty in one shell.

Although he lost two river mussels, Yunyi didn't blame himself too much, after all, this is not the same as the mussel meat that can be eaten at home?

After handing the mussels and pearls to Goku and sending them to the shore, he continues to dive into the deep water, searching for the large mussels, which only the large mussel belt can give birth to large pearls.

Many people think that the size of the mussel has nothing to do with the depth of the water, but this is not the case, and the mussel with a diameter of less than 20 cm is indeed not related to the depth of the water; However, those mussels over 20 centimeters will run into deep water and continue to grow, which is quite strange.

Because river mussels live on microorganisms and algae in filtered water, there are generally more substances in shallow water than in deep water, and it is said that river mussels should grow in shallow water with better conditions; However, many large river mussels are running into the deep water.

This is a mystery that has not yet been solved, and science has so far failed to reveal the cause of this phenomenon; However, one thing is certain, the older the mussel, the higher the nutritional value of its meat, and the better the effect of replenishing qi and blood.

In the joking argument of one scientist, the older these mussels live, the more cunning they become, or that the mussels can also have a biological crisis awareness and think that deep water is safer.

Yun Yi searched for a while in the water seven or eight meters deep, but he couldn't find a river mussel, the water here is too deep, and people have to come up to ventilate after diving down to stay under the water for a while, so there is very little time to find a river mussel.

Not far from Yunyi, a group of bear children and a few young teachers, as well as Long Xiaotian, were also looking for river mussels in the deep water, and if they followed Yunyi's footsteps, they would definitely find river mussels.

Sure enough, after a while, a bear child from Qingyun Mountain Village dug up a large river mussel of nearly 30 centimeters, sent it to the shore and dug it up, and there were indeed pearls in it, and there were three of them.

In this way, let everyone follow closely behind Yunyi, they firmly believe that they can find the river mussel by following Yunyi.

"Hey, I said Brother Long, you don't have to follow me, let's get too close!"

Yun Yi said with a sad face, just now Long Xiaotian also found a big river mussel not far from him, and there was also a pearl in it, which made Luo Xiaoyun very excited, and gave him a fragrant kiss in front of many people.

On the contrary, Yunyi, who has not been able to find a river mussel for a while, seems to have been 'robbed' by others.

"It's okay, I'll take a look behind you, you can just look for it!"

Long Xiaotian grinned and hugged his shoulders, his upper body did not move, and his lower body did not move. Stepping on the waterway.

Yunyi was helpless, and his heart simply swam to the deepest part of the river.

The water depth here can be at least twelve or thirteen meters, Yunyi tried to dive a few times, and he was able to barely reach the end, but the breath was not enough. (To be continued.) )
