Leo told the Chinese boss that he had been living in the countryside and rarely came to Havana, and this time he came to look for relatives, but the relatives were not at home, and just now he was strolling around the beach by himself, and found this dying fish, so he plugged it in and wanted to sell it for some money.

When the boss heard that he was not a local, he looked at Leo a few times, and saw that he was not dressed very well, so he said: "Such a barracuda can be sold in the market for 200-300 pesos, so let's see that you are also Chinese, I will give you 400 pesos, can you see it?"

Leo was overjoyed when he heard it, he didn't expect to meet a good person today. I thought maybe the money would be enough for him to live in Havana for a few days, and it should be fine when Robert and they find him. So he readily agreed, because the chef of this restaurant was already off work, so Leo had to take the money and find other restaurants.

He had money in his pocket, and although he didn't know the price of goods in Havana, he thought that 400 pesos should be enough for a few days, so he found a restaurant on this street that was still open and walked in.

The restaurant is not big, the decoration is very simple, but it is very clean, the owner is a middle-aged white man, he was not surprised to see Leo come in alone, and asked him in Spanish what he wanted to eat.

Leo didn't know how to communicate, so he said to his boss in English: "You can do anything, as long as you can eat enough." ”

The boss can fully understand English, it turns out that in Cuba, especially in Havana, although the official language is Spanish, but the general business or service industry will speak English, now Leo is relieved, do not have to worry about communication problems.

The boss served Leo a few very popular meals, and Leo ate quickly, and in a short time he ate several dishes and staples. He was really hungry, because he usually had snacks around him, and rarely when he was hungry, this was the first time he felt hungry, and now he was really hungry and collapsed.

After the hot food and soup were served, Leo's spirits were much better, and there were no other customers in the store at this time, and the boss was fine, so he sat opposite Leo and chatted with him.

When the boss also asked him how he could be alone, he said what he had said to the Chinese boss again. The boss asked Leo: "Actually, I noticed you when you first entered this street, you just held a big barracuda, right?" Sold it?"

When Leo heard him say this, he was shocked, could it be that the person in charge of the organization had found him? The boss said that he had just seen him, and he might have been too hungry at the time, and he didn't pay much attention to the people around him. Usually Leo will also observe the passers-by around him, this is his habit, because he can remember almost any face he has seen people, as long as that person is not going to have plastic surgery, whether he has become fat or sick, if he meets again, he will definitely be recognized by Leo.

Leo then took a closer look at the boss, although he hadn't observed it carefully at the time, but he also had some impressions of the people who walked by him, especially those who had also watched him. The boss did walk past him when he first entered the street.

Only then did Leo relax and know that the other party had no malicious intent, so he replied: "Yes, I sold it to the Chinese boss over there, and he said that the market price of such a fish was 200-300 pesos, and he said that I was both Chinese, so he gave me 400 pesos." ”

The boss nodded and said, "He's right, I saw that the fish you took was about 60 centimeters, and the market price was indeed around 300 convertible pesos, and he gave you 400 convertible pesos, which is a very high price." ”

Leo was a little puzzled when he heard the boss say the word convertible peso, is there a difference between convertible pesos and non-convertible pesos, so he asked, "Is there any difference between convertible pesos and pesos?"

The boss explained: "The convertible peso can be exchanged for foreign currency, the ordinary peso, also called the Cuban peso, can only be circulated in the country, it cannot be exchanged for foreign currency, 1 convertible peso is equivalent to 25 Cuban pesos, and both pesos can be used in Cuba." ”

When Leo heard that the difference between the two pesos was so big, he suddenly had a bad premonition in his heart, and hurriedly showed the peso given to him by the Chinese boss to the middle-aged boss, and when the middle-aged boss saw the peso in Leo's hand, he showed an expression that was really like this, and sighed and said, "You are taking Cuban pesos"

As soon as Leo heard this, he immediately became angry, he didn't expect that the Chinese boss just now already knew that he was also Chinese and lied to him like this, he didn't understand. Then I thought that this meal should not be cheap, so I asked, "Then how much is my meal?"

The boss said, "Your meal is 12 pesos, which is 300 Cuban pesos." ”

Although Leo was shocked when he heard the 300 Cuban pesos, he could still afford to pay for the meal, so he was at ease, he thought that it would be a big deal to catch another big fish like this, and now that he knew the approximate price, he didn't have to worry about being cheated next time.

The boss saw the change in Leo's expression and knew that Leo should still be able to get such a fish, so he said: "Look at your appearance, you are not Cuban, and you don't even know what Cuba's currency is." You don't have to look at me with such vigilant eyes, I won't ask where you came from. I know you can get another big fish like that, right, and if you can get it, I'll give you a fair price next time I buy it. ”

Leo was a little embarrassed when he knew that his lie had been exposed, but when he heard that the boss wanted to accept the fish he sold, he was a little puzzled and asked, "Boss, how do you know that I can still get this kind of big fish." ”

The boss smiled and said, "The first time I saw you and the fish you took, I knew that you caught the fish yourself, and the fish was killed by you with a branch." In fact, my family used to be fishermen, but it was only because the fishermen's lives were getting worse and worse that they changed careers and started a restaurant business. When I was a child, I heard that in this Latin American region, there is a kind of person who can catch fish directly with a fish plug underwater, but there are no people who can use this technique now, and the people who can use this technique are some local indigenous people, I didn't expect you to be a Chinese child can also use this technique."

Leo touched his nose a little embarrassed when he heard the boss say this, he couldn't tell the boss what skills he had, but he was able to catch a fish by relying on his long breath-holding time and vigorous skills. But when it came to technique, an idea popped into his head that he might try it later.

Leo didn't speak, and he acquiesced to the boss's statement, but the boss saw that he didn't speak, thinking that he was right and didn't want to say more, so he continued: "My name is Raul, and I hope you can bring me more surprises." ”

Leo nodded and said, "Thank you, Uncle Raul, my name is Leo, I will definitely get a big fish to sell to you, the price is easy to say." I'm going to get a bigger fish tonight, and I'll get it to you tomorrow morning." ”

Raul heard that Leo could catch fish at night, and asked curiously: "How can you catch fish at night, I heard that you can catch fish in that ancient way, and it is only during the day, and the sun has to be sufficient."

Leo smiled mysteriously and said, "This is a secret, by the way, Uncle Raul, do you have a harpoon at home, borrow it from me, I don't have anything suitable, I can't catch too big a fish."

Raul saw that Leo didn't say the reason, so he didn't ask more, and walked to the back of the restaurant with Leo, it turned out that Raul lived at the back of the hotel, his home was not very big, about 60 square meters, and there was a middle-aged woman sitting in the house at this time, and there were two girls about the same age as Leo next to her. Leo didn't follow up when he saw someone in the house, but just stood at the door and waited, and although he didn't enter the house, he could hear the conversation inside.

"Is the store closed so early today?"

"No, I'm here to get the warehouse key, take something out, someone wants to borrow it!"

At this time, the middle-aged woman glanced out of the door and saw Leo standing there, obviously he wanted to borrow something, and then the eyes of the two girls were also attracted by Leo, because the proportion of Chinese in Cuba is still very low, maybe less than 1%, and they are also very curious to see a very beautiful Chinese boy standing at the door of the house.

At this time, Raul said: "He wants to borrow a harpoon to catch fish, I will go and take out the original harpoon at home and borrow him to use"

"He can also harpoon fish, not many people can do it now, do you believe him so much?"

He had just caught a half-meter-long needlefish with a branch. What is there to believe, I told him that if he could catch a fish, he would sell it to me. ”

"Oh, I can't see it, such a little guy is quite powerful!"

After a while, Raul came out of it, with a key in his hand, and led Leo to the back of the house, and Raul's two daughters kept staring at Leo as if they were interested in Leo himself.

Raul looked at his two daughters, then at Leo, smiled and didn't speak, came to the door of the warehouse, opened the door of the warehouse, there were many things inside, but they were all neatly arranged. Leo saw at a glance a few harpoons standing in the corner, although they seemed to have not been used for a long time, but there was no rust at all, and the owner would often wipe them.

Raul asked Leo to pick a suitable one among several harpoons, and Leo walked over and picked up the largest harpoon, the front of the harpoon was mountain-shaped, very bright and seemed to be very sharp. Leo picked up the smallest one-handed harpoon, with only two forks at the front.

Raul saw that Leo took two handfuls, he was also very curious, and asked, "Are you so difficult that you can take one handful in one hand, I have to use both hands to use this big handful." ”

Leo said, "It's not that heavy underwater, I can use both, lend them to me." Then he saw a thick line on the ground, pointed to it, and said, "Lend me this too." ”

Raul saw that Leo could use it, so he lent it to him, and he was also curious about what kind of fish Leo could catch back, and asked: "There are many things here that I left when I was fishing, you can take anything else that can be used." ”

Leo was not polite when he heard this, and looked carefully and found that there was a pair of huge flippers on the ground. He thought that with this, he didn't have to use it all the time underwater, and that using flippers would save effort and move quickly, so he picked up the pair of flippers again. Only then did he walk out of Raul's warehouse, and after having these utensils this time, he thought that he would have to get a big guy back this time.

After saying goodbye to Raul, he took two harpoons and hung everything else on his body with a fishing line, and often walked to the beach. It's already past 9 p.m., and the nightlife in Havana isn't very rich, and there are basically no people on the streets.

Soon he was on the beach, and he sat on the beach and adjusted his breathing, his brain racing rapidly, perfecting the thoughts that had just popped into his head. Half an hour later, Leo got up and walked out to sea, but he left his harpoon and flippers on the shore. He came to a reef in the water, put his hands in his mouth, and opened his mouth to let out a silent cry at the reef. Although ordinary people can't hear it, Leo himself can hear it. He is emitting ultrasound now, and when he practiced sending infrasound waves before, he was already able to emit ultrasound waves, and this ultrasound wave does not care whether the sound is understood or not, as long as it emits a smooth sound wave.

In fact, ultrasonic waves and infrasound waves are both sound waves, but their wavelengths are different, the higher the frequency of sound wave vibration, the shorter the wavelength of sound waves, and the easier it is for such sound waves to be bounced back when they encounter obstacles, so that they can locate things in front of them.

What he just thought of was to use ultrasound to locate where there are fish, no matter how big a fish is, it is difficult to bounce back the echo waves, but the fish schools are different, they will have a large group, so that the bounced sound waves can be received, and where there are schools of fish, there will be big fish.

Leo tried the reef several times to determine which frequency would bounce best and that he could hear. He gradually moved away from the reef and emitted ultrasound waves to determine his distance from the reef.

After many experiments, he found that the closer the distance, the more impossible it was to determine the distance, but the farther the distance, the better the effect of the determined distance, because it was used to determine the distance to the obstacle by the length of time it had been receiving the echo. But the sound that Leo can make also travels a certain distance, so now he can only determine whether there are fish within 500 meters, which is not a good thing for Leo, because the range is too small, he can only rely on luck, and pray that wherever he walks, there will be fish within 500 meters.

Time passed quickly, four hours had passed since he was back at the beach, and Leo knew that the time was almost up, so he picked up his harpoon and headed to the bottom of the sea.
