There are many undercurrents on the bottom of the sea, and in order not to be swept away by these undercurrents, the two found a strong reef, put a rope on themselves, and stuck an iron anchor on the reef.

Jumping down the cliff, some creatures on the bottom of the sea also became more numerous, a few carnivorous fish opened their fangs and swam over, quite large, all of them are extraordinary species, they have not seen humans, for species that have not been seen, these fish with abnormal brains choose to bite and try.

They are surrounded by the carcasses of mayfly creatures and crushed prey, which is their extraordinary ability, whirling the sea and bringing the debris of the sea to smash their opponents.

With Mu Ning's heartbeat, the invisible cold force was pumped into the bodies of these fish, and Mu Ning didn't care where their key points were, freezing all the organs in the fish's bodies.

Against these sea species, the truth sophistry does not meet the trigger conditions, and the Void Fist is too rough, and the blood will attract other carnivorous creatures.

Ice pumps are the perfect fit.

"You really have other extraordinary abilities, damn it, how can we say that it is also a relationship between birth and death, and you even hide this from me......"

Mu Ning just glanced at it, and the menacing strange fish turned their bellies and floated to the sea, how weird they looked, of course, they couldn't escape Yu Yusi's eyes.

But it doesn't matter, as she said, the interests of the two are getting closer and closer, and there is a faint tendency to develop into an alliance, so it doesn't matter if it's thorough.

"This is close to the island, and the currents on the bottom of the sea should have stopped, and such a strong current is probably inseparable from these fish."

Mu Ning said, his pupil observed the surroundings, ignoring Yu Yusi's question, although the oxygen tank is a product of cutting-edge technology, and the use time is not short, but it is not a waste of small talk.

"You're very observant,"

Yu Yu Si Zhengsedao,

"These fanged fish are not ordinary people, they are vortex fish, hundreds of years ago, they were in groups, and the combination of extraordinary abilities was a huge whirlpool, and the ship sank because of them...... But now, cetaceans have expanded their territory and eaten a lot of the eddy fish in the sea, and the eddy disaster in this area has gradually subsided. ”

No wonder the ship was left unattended for so long, it turned out that there was such a fish in the sea.

"Is that wreck right in the middle of the vortex?"

With the help of the pupil, Mu Ning could see the bottom of this seabed cliff, the whirlpool rolled up some impurities from the seabed, there were fish bones, shells and stone fragments, as well as some human-caused garbage, these things circled endlessly in that area, like a barrier.

"Well, the Vortex Gate, they create a portal to defend against natural enemies, and it is also the ability to prey, they will pull their huge prey into the Vortex Gate and slowly eat away, but because of the decrease in the number of Vortex Fish, the Vortex Gate no longer has that function."

Yu Yusi said.

In fact, the wreck has been lying on the bottom of the sea for many years, and some people speculate that its disappearance was due to being attacked by vortex fish, but even if they did, no one would be willing to expend so much effort to fight the incredible number of vortex fish here.

And now it is different, the cetaceans have expanded their territory here and cleaned the vortex fish, which is the research topic of Professor Mi Dongfang, but he has not had time to publish it, so the defense of the vortex gate has been greatly reduced and only Yu Yusi knows.

This operation has been in her plan so far, and Dry Ze is not something that is so easy to plan, and once it is released, it will definitely be targeted by some powerful organizations.

Therefore, it is fitting to take the things before they do, and use the reason of internship with the expedition.

"How do you get through this vortex gate?"

Mu Ning said, he has a way to get over, at that time, the black snake roared in the eyes of the dragon heart to create an iceberg, although that kind of Cheng Muning can't do it for the time being, but give him time to make a big difference.

Of course, it is easy to block the vortex gate with icebergs.

"Since I plan to come over, of course there is a way!"

Yu Yusi's skills are all in his head, and he can't talk about any last resort, and he can still afford to be brave and strategic, of course he has thought of this situation.

She took out a small black box from her bag, opened the safety on it, and the red letters on it flashed and began to count down.

Mu Ning: ?

This shouldn't be the kind of thing he thought, right?

"Let's go a little upstream, and then it won't blow ourselves up."

Yu Yusi reminded Mu Ning.

"So your solution is to blow this place up?"

Mu Ning said that she didn't understand her brain circuits, and that the undersea explosion was something that people could think of? It's a fragile cliff!

"That's right,"

Yu Yu thought about it, and the black box in his hand was pulled by the turbulent current, and quickly fell into the center of the vortex.

The box with flashing red numbers quickly disappeared in a swirling pile of debris, Mu Ning counted the time, and two minutes later, a strange muffled sound came from the vortex gate.

It didn't have a lot of power, but it was a roaring sound from the vortex gate, Mu Ning had heard this voice, it was the ethereal whale song that he heard on the island yesterday!

"Biomimetic bombs! The blasting power is secondary, and the bomb explosion mimics the angry roar of a cetacean, which is much more useful than a simple explosion! ”

The vortex gate collapsed in an instant, and the whirlpool fish with hideous fangs escaped from the portal and scattered in all directions, lest they be used as a meal by the whale.

"With such a loud voice, aren't you afraid to lure the whales over?"

Mu Ning was taken aback, this idea was quite bold, it was indeed more reliable to scare the vortex fish away than to break into their nest directly.

"It doesn't matter, when the whale voice that appeared in the explosion was translated, there would be no one of the same kind who was boring to talk about, not to mention, there are so many vortex fish mats outside."

Yu Yusi explained, the vortex gate disappeared, and a black hole appeared in the cliff at the bottom of the sea, and the night vision function of the diving goggles was turned on, and the two went deeper.

There are more and more impurities in the seawater, and at a certain point of diving, the sea water with impurities and the clean sea water are clearly distinguished, and the rocks on the bottom of the sea seem to have large and small holes, which are the places where the whirlpool fish spawn.

In addition to this, debris such as whalebones, iron anchors, and some large and small fishing boats are also piled up here.

"Found it."

Yu Yusi found a large, black, moldy ship in the flat reef sand at the bottom of the sea, dilapidated and half-hidden in the sand, like a grave.

"Is this an ancient ship? It's huge! ”

It was also the first time Mu Ning had seen such a wooden ship, even though the wood that constructed the hull had decayed most of it, but he could still see the huge body of the ship.
