After saying goodbye to Xiuzi, the three of them embarked on a journey again, but unlike before, all three of them carried an oxygen tank on their backs.

In Xiuzi's research room, after Nebula raised the question that it was inconvenient to talk in the water, Xiuzi immediately handed Nebula a communication device for each of the three of them, and the three of them only needed to clip the communication equipment to their collars, and the three of them could have normal conversations underwater.

In the eyes of ordinary people, this kind of appearance of carrying an oxygen tank could not be more stupid, and the three of them even laughed at each other's appearance of carrying an oxygen tank, especially the handsome Heath, who carried this ugly oxygen tank on his back

Why is it still beautiful, Nebula thought secretly with a red face.

After a while, the three of them walked to the bottom of the second basement floor of the Tower of Babel, which is the bottom of the Tower of Babel, and further down is the mud of the sea, and there is no other way to continue going down for the time being, but on the right, there is a big hole in the wall, which should be the exit from the bottom of the sea!

The three of them swam out of the big hole one after another, and came to the fork in the bottom of the sea described on the map.

After entering the fork in the road, the three were stunned by the scenery in front of them

A soft white light came from the lighthouse in the distance, and the white light was reflected in all directions by the purple magic crystals placed near it, which could refract light, and the soft light filled the entire seabed.

Schools of exotic fish dance in schools in the water, while mischievous diving penguins and baby seals chase and play with the fish

Well, it should be said that it is more appropriate to prey on prey.

Fortunately, neither fish, diving penguins, nor baby seals are aggressive creatures, and they will not easily attack others except for normal predation.

This also made Nebula breathe a sigh of relief, they didn't want to run into a bunch of undersea monsters that were difficult to fight and kill as soon as they came. They weren't McGonagall's swordsmen, who had a strong desire for their opponents, and they wouldn't have shied down if they could save a little more effort.

From the fork in the sea nebula, they swam all the way to the right, well~~~~ How to say it, the swimming posture of the three of them is more or less problematic.

Nebula and Ryan, who have never been in the water, are not swimming at all, they are just simple strokes with their hands and feet, and they will even go backwards instead of advancing.

So the two of them are actually relying on teleportation on the ground at the bottom of the sea, although it costs more mana to use teleportation on the bottom of the sea than on land, but it's better than tossing around in place!

Of course, they flutter twice once in a while, and then use teleportation when they hit the ground, and if they practice like that, they will be able to learn to swim one day.

Shinas is much better than Nebula and the others, he can swim far just by moving his feet slightly, but occasionally there are some small mistakes that make his body unbalanced, and Shinas rolls up and down twice to stabilize his body.

Shinas was very helpless, if he wasn't worried about exposing his strength in front of these two little guys, as long as he raised the domain shield, the water flow in the domain would become a part of his body, as long as he controlled the flow of water to move forward, he would be able to reach the underwater world in a few minutes.

Where else would you need to swim as slowly as you do now?

However, it's also good to see the underwater scenery once in a while.

Looking at the two imps behind him, Shinas smiled slightly.

It's been more than five years since the last time I was in the underwater world! The scenery under the sea is still so beautiful, if you are not the queen of the Holy Land, it is also a good choice to grow old with your loved ones in this underwater world

★?????????????????? ★

After a while, the three of them left the undersea fork and came to Crystal Canyon.

As the name suggests, Crystal Canyon is a canyon with many magic crystals, but most of these magic crystals are ancient magic crystals that have existed on the bottom of the sea for many years, and the magic contained in the crystals has long been dissipated.

Their function is to reflect and refract the light of the lighthouse under the illumination of the lighthouse, so that the bottom of the sea is full of light.

Nebula and Ryan had seen this kind of bright seabed for the first time, and when they passed through the basement level and the second basement of the Tower of Babel, there was no light there, and if it weren't for Ryan's constant flashing spell on the side, keeping the light guided, I'm afraid Nebula wouldn't even be able to find the exit, let alone find the research room to find Xiuzi.

Crystal Canyon is inhabited by the grumpy underwater creature of the Blue Thorn Dolphin, which will swell up and shoot all the spikes on its surface at the enemy.

It only takes three seconds for their spikes to grow out of their bodies again, which means that if you mess with a blue thorn dolphin, you'll probably be shot to slag and its spines won't run out yet.

However, it also takes magic to condense the spikes, and the blue thorn dolphin generally does not chase so relentlessly, at most two deterrences are enough.

Nebula was very careful when they passed through the Crystal Canyon, for fear of angering a blue thorn dolphin, and it was very stupid to fight against the underwater creatures until they were unfamiliar with the underwater fighting methods

After a while, the three Nebulas finally passed through the Crystal Canyon and came to the red coral forest.

Red coral is a rare herb that can only be seen at the bottom of the sea, and the potions it makes are very good for petrochemical and shield armor elixirs, and it is occasionally used as a material for equipment boosters, which can increase the toughness of equipment and is a good choice for medium and low-level accelerators.

After seeing these corals, Nebula's first thought was to collect some red corals, even if they don't need them now, they will always need them in the future.

As an alchemist, Ryan also thinks the same, refining all these red corals into accelerators, and adding some accelerators to the refining process of magic equipment, the performance of magic equipment will be greatly improved.

Perfect!!

Nebula and Ryan glanced at each other, and they both saw the unabashed thoughts in each other's eyes.

Suddenly, the atmosphere between the two became awkward, if the other party proposed to collect these red corals first, then what should they do? Do we have to be humble among brothers?

At this time, the voice of the Hiss mentor came from the communicator: "Zi~~~Zi, hey!" What's going on with the two of you? Why did you suddenly stop and not leave? ”

Nebula immediately told Shinas what had happened, hoping that Shinas would wait for them to finish collecting the pile of red coral before setting off.

"You two idiots, if you can collect red coral here. With so many people passing through the red coral forest every year, wouldn't they have collected all these red corals a long time ago? Can it still be your turn? The red coral is inhabited by highly poisonous purple thorn dolphins, and if you dare to touch these red corals, you will be chased by a large group of purple thorn dolphins! After saying this, Shinas continued to swim forward, ignoring Nebula and Ryan, who were stunned behind him.

Ryan and Nebula glanced at each other again, and they both saw in each other's eyes the shock that Hiss Mentor knew so much, could it be that Hiss Mentor had been here before?

Next is the Conch Hill, where many conch creatures live, but they have been asleep for a long time, as long as they don't disturb them, they generally won't wake up, which makes many people think that the creatures of the Conch Hill are only baby walruses and baby sea lions.

The road of the conch hill is very short, and they passed through the nebula after a while, and I don't know if it is because of the conch, the little sea lions and walruses here did not do anything to the nebula even if they were angry when the nebula passed through their territory.

Finally arrived at the fork in the West Sea, and you only need to pass through this fork in the road to officially reach the underwater world.

The fork in the West Sea is a three-way junction that connects the Conch Hill on the top and the deep-sea canyon on the bottom, and the entrance on the far right is the Nebula's first destination, the underwater world.

Maybe the good luck in front ran out, after entering the fork in the West Sea, Xingyun and the three of them were immediately surrounded by a group of small sea lions and small walruses.

You must know that the little sea lion is a forty-three-level undersea monster, and the little walrus has a forty-seven-level strength, so many powerful monsters are simply a nightmare for the Nebula.

What's more, because this is the bottom of the sea, the flame orb released by Ryan will be extinguished halfway through the flight, even if it is a powerful flame arrow, hitting these rough-skinned and thick-skinned underwater creatures in the water will not be able to cause them any effective damage.

Nebula's ice magic is the same, even if one of them freezes with mana, the others will rush forward, and it won't work at all.

Underwater, after such a minute or two, the frozen baby sea lions and baby walruses can break through the ice again.

It's simply incomprehensible.

Nebula could only barely resist with the thunder magic that he was not very familiar with, and Ryan could only use the poison fog technique with the twentieth level magic double tap to drag the group of little sea lions and little walruses.

If it weren't for the paralyzing effect of the lightning magic and the weakening effect of the poison fog technique, I'm afraid that Nebula and Ryan would not have been able to hold it for a long time.

But the unskilled are not skilled after all, if you want to use the half-baked thunder magic of Nebula to defeat these little sea lions and baby walruses, or wait for Ryan to poison these thick-skinned sea creatures with his nascent poison magic, wouldn't it be a long, long wait?

The little sea lion and the baby walrus gathered more and more, and gradually Nebula and Ryan became unable to take care of Shinas, and if they still took care of others at this time, it would be like looking for death.

Faced with such a tricky situation, Nebula quietly connected his spiritual power to the dummy model in the space ring, although the use of costume change may have serious consequences, but at this time the arrow has to be sent.

Nebula would rather endure the pain of using and changing clothes one more time than be beaten to death by a group of unintelligent underwater creatures here.

Probably annoyed by the harassment of these underwater creatures, Shinas didn't expect these two little guys to be able to save him, and when he saw that the situation in front of him was very urgent, Shinas silently opened the Rubik's Cube that she had taken out of the space ring and held in her hand earlier

(I'm afraid adventure fans haven't thought about using fire magic in the underwater world, isn't it strange that the power of fire magic in the game hasn't diminished in the slightest?) ）
