Zhang Zi'an remembered it very clearly how 52 Hz surfaced fiercely last time and last time, leaving almost no room for him and the minky whale to avoid it, but this time it appeared two or three hundred meters away from the boat, and its tail fin slapped the water surface lazily and approached this side at a slower speed.

The whale has generally poor vision, but at least the general outline of the boat can be seen at this distance. It must be both surprised and puzzled, why is the "whale" that can emit the same band of audio as it is so small?

It swam out an arc, as if it was going to circle the boat and observe it.

Seeing it like this, Zhang Zi'an knew that Shihua's singing had worked, no longer the irritable brother... or sister before, but he still couldn't tell how effective it was.

As it approached, he complained secretly, because the pressure of a giant approaching at a slow speed was even stronger than the shock caused by its sudden appearance. It was like a train coming at a low speed and for some reason he could only stay on the tracks, hoping that the train could stop in time.

When it got closer, he finally observed some details on its body surface.

As for whales, their appearance is very unique, and they can even be said to be a bit strange. They are about 25 meters long from beginning to tail, and maybe a little longer. After all, they have no reference objects and rely solely on visual inspection.

It looks close to a baleen whale, but its size is thicker than a baleen whale. Its head is slightly curved like a blue whale. The baleen is black and its back is blue-gray like a blue whale. However, the wrinkles on the flanks are white like a baleen whale, and the other flanks are also blue-gray marks like a blue whale.

In addition, its dorsal fin is so small that it is not commensurate with its size, it is as tall as a sword like a sword, which is why it almost mistakenly mistakenly thought it was a shark.

During its swimming process, it occasionally jumped out of the water and then fell back into the water, splashing a lot of waves. Zhang Zi'an took the opportunity to observe the characteristics of the bottom of its body through a telescope.

First of all, it is definitely not a blue whale. Secondly, although it looks like a baleen whale, there are several signs of baleen whale that are not. For example, the right chin of the baleen whale is gray-white, while the left chin is gray-black, which looks like a shaved yin and yang beard, but it is not. The color of its chin is uniform and uniform.

The same is true for the color of baleen. The baleen on both sides of the real fin whale is different in color, and it is the same.

When it turns sideways, the slightly exposed baleen board is thinner and not as thick as a blue whale.

Based on the above characteristics, Zhang Zian is at least 80% sure that it is a mixed-race child born from blue whales and finch whales. As for the remaining 20%, it must rely on DNA identification to be sure.

Throughout the second half of the 20th century, humans only confirmed the mixed-race children born from blue whales and fin whales. Even if the 10 or 20 years of the new century were added, this number would definitely not exceed 10, and it might not even increase at all.

Obviously, the mysterious 52 Hertz is another mixed-race child who was not discovered. The mixed-race caused its unique voice and also caused its loneliness.

In addition, during its swimming process, Zhang Zi'an confirmed that it was a female whale.

Mixed blood across species often means infertility, such as the well-known mule, but he believes that 52 Hz is different, and if it meets the right person, it is still possible to become a mother.

Mules are infertile because the number of horses is 64, donkeys is 62, and the mules are born with 63, which are not paired, but the number of chromosomes of blue whales and fin whales is 22, and the number of chromosomes of mixed-race children is still 22.

If nothing unexpected happens, the chromosome of 52 Hz is paired and has fertility.

It has long been adultery, so it can't wait to swim over after hearing the sound, looking for a partner?

Unfortunately, it was about to be disappointed, there was only one inflatable boat here.

Zhang Zi sat quietly in the boat, using slow motion no matter what he did, so as not to panic it with quick action.

When 52 Hz appeared, in order to avoid making it too excited, he turned off Shihua's voice and left the speaker in the water.

It may be because of the poor vision, or it may be because it is eager to find out, it is swimming closer and closer, and even faces Zhang Zi'an's sight.

Its eyes are different from those of minke whales. The upper and lower eyelids have two obvious folds, such as human double eyelids and eye bags, and the eyeballs are blue and black, with almost no whites visible, and they are as bright and shiny as huge sapphires.

Then, its eyes narrowed slightly, took a breath, and its body sank quickly, causing the sea water to pass through its body and disappear from the sea.

Has it gone?

No, no.

If a drone was photographed from directly above, he would see a huge shadow quietly swimming under Zhang Zi'an's boat in the blue sea. As long as it suddenly floated out of the water, he would experience the feeling of flying.

Zhang Zian also knew his current situation and dared not move around. He was wearing a life jacket and had a lifebuoy on his hand. Anyway, whales don’t eat people, and as long as they can’t drown, it’s easy to say.

It took more than ten seconds for the huge shadow to swim past the assault boat.

It floated on the other side of the boat and sprayed a mist.

At this time, the wind blew from the land to the ocean, and some mist was blown on Zhang Zi'an's body, carrying a strong smell of fish and shrimp.

It swung its pectoral fins, turned its semicircular bend, and swam back. This time its eyes were full of expectations and desires, so strong that it almost overflowed, even Zhang Zian was deeply infected.

Thirty years of loneliness finally responded.

"Hi!"

Zhang Zi'an waved to it and greeted him with a smile.

"You heard it right, the sound was made by me." He patted the rubber side of the assault boat, "This is my ship, let's say hello to you."

52 Hertz obviously couldn't understand his words, so he paraded around the boat repeatedly, and from time to time he dived into the water and swam down the boat again, as if looking for a similar person that did not exist.

As it was unable to find its target for a long time, it seemed increasingly anxious and its movements became larger and larger. The waves raised made the boat undulate like a roller coaster. Although it was not as good as a capsized boat, it would be a matter of time before it would be a matter of time.

Zhang Zian underestimated its desire for his kind, and thought that he would leave with satisfaction after hearing the response, but seeing it like this, it would seem that he would not give up until he achieved his goal.

If it doesn't leave, then he can only retreat.

When it swam in front of the charge boat again, he quietly activated the motor, drove to reverse, and tried to backward and retreat to the coast.

However, it immediately noticed his intention, and chased after him in a flash, bypassing the boat and blocking his retreat, and not letting him go.
