"Shooting fish" is just a fish that Lupin remembers, not the real name of the strange fish in front of him.

Lupin just remembered that in his previous life, there seemed to be an ornamental fish that could shoot arrows at the insects above the surface of the water, and the high-speed water was like a bullet, knocking the insects into the water, and then feasting!

He has a friend who raises this kind of fish at home, and once he went to his house as a guest, and he deliberately put live flying insects into the fish tank, so that the shooting fish performed a "unique skill".

However, the ornamental fish seem to live in shallow water, and their targets are often insects that stay on branches and rocks not far above the water. But here it is the bottom of the sea...... It can only be said that there are similarities between the two, but Lupin actually doesn't know what the strange fish in front of him is called.

It's just a small fish, and Lupin is naturally not afraid.

In the face of the water arrow, he deliberately picked it up.

The palm of his hand shook, Lu Ping suddenly felt a little surprised, there was a gap of about two meters between himself and the palm-sized fish, and when this water arrow hit his palm, it still made his palm hurt slightly!

This power is no less than the full force attack of the undead!

And you must know that the person who made this attack was only a small fish less than 20cm long......

Miss Bottle looked a little frightened, and her body writhed, and she was at least five meters away from the entrance of the cave.

But it was clearly unwilling, suspended in the sea five meters away, tilting its head to stare at the strange fish in contemplation.

After a few moments, it swooped down and came back again...... On top of the head is a turtle shell with a diameter of half a meter!

I don't know which turtle left a legacy after his death, but now, it has become Miss Bottle's "hard hat", and the relatively fragile abdomen of the turtle shell has been stabbed by Miss Bottle with her nose, leaving only the thickest and hardest part of the back armor, and then it is on the head. The bulge on the dolphin's forehead just stuck it.

Miss Bottle slowly approached the cave this time, carefully adjusting the angle so that the turtle shell was always facing the hole.

Soon a few more water arrows were shot in the hole! But they all hit the turtle shell, and except for the sound of "Dongdong Dongdong", there was no merit.

And wait until you get close enough...... Miss Bottle suddenly took off her helmet and sped up!

The spear-like slender snout was directly inserted into the cave, and the strange fish that shot the water was instantly poked to death on the cave wall.

Lupin didn't intervene the whole time, watching from the side, and the IQ assessment of Miss Bottle in his heart suddenly improved greatly again.

Predators actually know how to use tools, and this tool is not ready-made, but has to go through a certain amount of processing - if the abdominal carapace is not broken, the turtle shell cannot be worn on the head.

In fact, this was not the first time Lupin had been amazed, he had just discovered the secret of Miss Bottle's ability to live in a canyon and keep her breath - she was able to find some bubble-like holes in the cliff face, like a pearl spring! Then turn sideways to block the air hole and breathe.

It looks like the gases should contain oxygen.

"Chirp." Miss Bottle is feasting.

Lupin leaned over as well, his fingertips running across the blood-stained water, and putting a little into his mouth.

[Obtained 100% ...... of the "Archback Pufferfish" gene]

Lupin was overjoyed.

He hadn't actually heard of this species because he didn't know much about marine life in the first place.

However, I have collected a lot of creatures in this submarine canyon today, and one of the genes that I am most interested in at present is this "bow-backed pufferfish"!

He could roughly see just now that the attack method of this deep-sea fish is likely to absorb a large amount of seawater in the stomach first, and then squeeze the water flow into water arrows by contracting the muscles of the whole body.

The name pufferfish also reminded him of the familiar "pufferfish", as many pufferfish seem to be able to swallow large amounts of seawater to inflate their bellies, which further confirms Lupin's speculation about the principle of its attack.

And with a body size of only 20cm, the water arrows shot can actually reach the power of an immortal.

Lupin wanted to know what kind of power the water arrow could achieve if he integrated this ability into his dolphin form and squeezed the water flow with his more powerful muscles.

What's more, it's a long-range attack!

Undoubtedly, it opened up a new way of thinking for Lupin, who used his smart dolphin form to fight the undead, but he still had to rely on himself to hit and cut, and it was easy to get injured in the process.

And although he can also use Pandora material to forcibly blend pangolin scales, rhinoceros skins and other things into the Wisdom Dolphin form to increase his own defense, but that will actually do more harm than good! Lupin had already tried it, and as a result of the chaos, the swimming speed of the dolphin form was greatly reduced, and it even began to produce deep-sea anesthesia.

The drop in swimming speed is easy to understand.

The smooth, streamlined skin, which dolphins have evolved over the years, is designed to minimize underwater drag, compared to the surface structure covered in pangolin scales, which undoubtedly greatly increases friction.

The soft skin of the dolphin, as well as the tiny spongy structure under the skin, can control the skin to rise and fall one after another during high-speed movement, eliminating turbulence and further reducing resistance! The use of rhino leather, which is up to 5cm thick, undoubtedly makes this subtle skin manipulation an empty talk.

As for deep-sea anesthesia.

Lupin didn't figure out the principle, he only knew that when he used the soft body of the dolphin, he would not feel uncomfortable whether he was going up or down quickly! However, after changing to a hard and sturdy scaly body, it is more likely to produce many manifestations of deep-sea anesthesia and decompression sickness......

In the end, it can only be boiled down to the fact that the body structure of every animal that has evolved successfully is a complex system that has been tempered and tempered, and if it is changed casually, there may be problems that are difficult to explain.

"Okay, today's harvest is enough, it's time to go back and report the news." After Lupin got the genes for the pufferfish, he also moved to leave.

This experience was very magical and opened Lupin's eyes, but calculating the time, it had only been about an hour since he met the group of undead.

"Life Canyon, come back next time." Lupin secretly remembered the location of the canyon in his mind and began to float upward.

In the process, he silently loaded and re-transformed into a six-meter-long dolphin form.

"Goodbye, Miss Bottle." Lupin tried to pronounce the words in the voice of a dolphin, but the sound was still awkward, and Lupin was stunned for a moment when he saw Miss Bottle.

It followed Lupin all the way upstream, but stopped when it reached the crack at the top of the canyon.

Stopped in the less toxic waters of the canyon and kept looking at Lupin away.

————

A moment later.

Lupin returned to the Crystal Palace in Fishman form, and as soon as he entered the range of the signal base station, he received several urgent messages from the Transcendent Dedicated Channel and the City Management Channel.

"Uh, I don't need to say it, Crystal Palace already knows?"

When Lupin saw these messages, it turned out that the transcendents urgently stopped going out to hunt, and the patrol team also stopped patrolling.

Crystal Palace has announced that it is in a closed state and everyone is not allowed to go out!

The reason for this is that the undead in this area have clearly united and are searching for the location of the Crystal Palace...... There seems to be a "king" behind them, and it is speculated that it is likely to be a four-turn immortal! In order to prevent the other party and the undead under his command from discovering the location of the Crystal Palace, no one is allowed to go out.

"Everyone can't go out, but those who have already gone out can't be contacted, because the signal base station can't cover that far." Lupin frowned slightly, "In other words, we can only see these warning messages when everyone returns one by one as originally planned......"

"Uh, no." Lupin's heart suddenly tightened, "Isn't my mother a member of the geological exploration team?" I remember these days, the whole geological exploration team was mobilized to explore the surrounding waters for the veins...... She wouldn't have come back yet, would she? ”

Hurriedly use the electronic bracelet to contact Yu Xin!

But it was like a stone sinking into the sea, and no one answered for a long time, and it was obvious that she was probably not in the Crystal Palace at this time.

"Damn." Lu Ping became nervous and hurriedly contacted his father Lu Xuejiang.
