Downstairs, Pegasus is still surrounded by fans and customers who have heard the news, and everyone wants to take a photo with it before the movie is released, because they feel that it will become a big star in the future, and there may not be many opportunities to take a photo together.

Zhang Zi'an picked up the battery that was placed in the corner of the wall to charge, opened the compartment and connected it to the motor, and confirmed that the power had been charged to 100%.

Wang Gan noticed his movements and knew that he was going to sea by boat again, otherwise he would not be carrying a battery, so he came over and asked, "Master, are you going whale watching again?"

Jiang Feifei also heard the news of the upcoming release of the movie next door, although she was not interested in the movie, but her classmates knew that she was working here, and asked her to inquire about some of the latest news, anyway, the aquarium had no guests for the time being, so she also came to the pet store.

"Manager, when are you going to take me with you for whale watching?" I've bought all my life jackets...... she asked expectantly.

"Well...... It should be soon. Zhang Zi'an smiled, "Don't worry, wait for the right time to come, everyone has a share." ”

Jiang Feifei was overjoyed when he heard his tone loosening.

Before, he was very nervous because there was a moody whale at sea, but as long as the 52 Hz matter can be resolved smoothly, it is no longer a threat to whale watchers, and it will be much safer to go whale watching at sea.

He said a few more words, turned around, got into the car, and headed for the sea.

After a while, he stopped at his old position by the sea and dragged the assault boat out of the compartment.

Due to a long spring rain that lasted for two or three days, the temperature was a little cooler today, and the sea level seemed to be a little higher than usual, and the foaming waves rushed down to the beach and crashed against the reef.

Zhang Zi'an inflated the assault boat while repeatedly thinking about the steps of today's action, 52 Hz understands Shihua's singing, what if you don't understand?

He thought about how to deal with different situations in order to be relatively safe, but the sea is vast, and there is no perfect solution, at least to ensure that he comes back safely.

The assault boat was full of air, and he briefly looked for any air leaks, then pushed the boat out into the sea, started the motor, and headed out into the sea.

Visually looking at the same thing as the last time, he turned off the motor, inserted the memory card into the underwater speaker, and started playing.

Once he had it done, he put on his headphones again, paused the playback at regular intervals, and listened to the sound of the ocean floor through the underwater pickups.

Countless mysterious and complex voices surrounded him again, some of them had heard it, others had not, hadn't it been a few days, and there was a new guest in the nearby seas?

It would be great if the waterfront of the city, which had been barren for a long time, could take advantage of the precious time of the fishing ban to return to its former life.

Listening to the sound of the bottom of the sea, his mind unconsciously wandered a little, and his heart was surging at the thought of the upcoming release of the Pegasus movie, the excitement of the mysterious trip to ancient Egypt, and the worry of the cat abuse incident that had not been solved for a long time, and the damned statue of the cat god was still missing......

At this moment, a distant sound like a train whistle suddenly sounded in his ears, at first far away, somewhat dull, as if it had come from a tunnel, and soon it was getting closer and closer, suppressing all other sounds, causing the whole valley to echo.

The other voices seemed to know that the giant of the sea was coming, and they suddenly fell silent, or fled as fast as they could, as quiet as a pond before a storm.

Zhang Zi'an perked up and broke away from the state outside the spirit.

He had listened to the recording before 52 Hz many times, and was already familiar with its sound, but today the sound seemed to be different, more urgent, shorter, and heavier than the last time, like a wanderer who saw his hometown from afar, leaving behind all the burdens in his hands, and rushing to his parents and relatives at the door of his home.

He glanced at the small LCD screen, which showed an increase in sound intensity at an even speed, proving that it was swimming almost straight in this direction, faster than ever.

With the experience of the last time, he estimated the time, and when he felt that it was about the same, he put away the pickups, kept only the speakers, started the motor, and retreated a short distance in the direction of the coast.

This distance is very delicate, in fact, it is not a safe distance, but Zhang Zi'an decided to take a gamble, he believes in Shihua's efforts in the past few days. At this distance, even if something goes wrong, you can probably swim back to the shore.

He couldn't retreat too far, and if 52 Hz was too excited to chase after him, and its huge body would probably run aground on the shore, then he would be the culprit, trying to help it, but ending up killing it.

Zhang Zi'an took off his headphones, his eyes cruised on the undulating sea, his hands grabbed the sides of the boat on both sides, and his heart was full of sweat.

It is impossible to say that it is not nervous, a great beast is about to appear, but I don't know how it intends to appear, will it rush out from below and lift the boat into the sky?

Well, the latter is probably impossible, and if 52 Hz is a hybrid offspring of a blue whale and a fin whale, it must have inherited some of their characteristics - although the mouth of the blue whale is extremely large, its throat is so narrow that it cannot swallow an adult, and it may even be blocked by plastic bags floating in the sea, which is how some blue whales die...... As a result, blue whales instinctively avoid devouring larger creatures.

Of course, Zhang Zi'an didn't want to verify whether this statement was correct or not.

Suddenly, out of the corner of his eye, he caught a small black dot moving quickly, and quickly picked up the telescope to look over.

It was a dorsal fin that pierced through the sea like a sharp blade and stabbed straight in the direction of the boat, with a swinging tail fin faintly visible behind it.

If it is a person who does not know about marine life, sitting in an eggshell-like boat like Zhang Zi'an, and suddenly sees the towering dorsal fin rushing towards him, I am afraid that the first reaction is that a shark is coming, and then the second reaction is to be scared to pee on the spot.

Zhang Zi'an was also nervous, but when he saw the tail fin behind the dorsal fin, he put his heart back in his throat.

It's easy to tell a shark from a whale at sea, and while their dorsal fin can sometimes be confusing, there is a fundamental difference in the way their tail fin swings – sharks swing their tail fins left and right, while whales swing their tail fins up and down, so the owner of this dorsal fin is a fake whale.

Burst!

It approached, slowed down, and spewed out a towering arrow of water, and half of its body rose to the surface.

Exactly 52 hertz.
