The seas have too many uncertainties. There are too many unknown monsters here.

It has been two days since the time when I encounter killer dolphins. After that, I encounter some other killer dolphins. Thanks to my experience in fighting against them, I no longer has difficulty when I fought them. But there are more of them than I thought.

Even today, I encounter at least fifteen of them. Maybe this is near their nest.

This time, I swum further from the shore. There should be more treasures I can get other than pearls. I already have a lot of them stocked on the empty island, but I still see some at the bottom of the sea. At least I won't have any trouble of empty stock for a while. But they were all just pearls though.

This time, I swum to the bottom of the sea and swum around there. I saw several giant crabs hiding under the sand. I wanted to have some of them for lunch. Maybe brought home some of them.

I heard from Sam that some sea animals are difficult to obtain, so she hoped that I could capture some of them to breed. Then we can have a crab farm or something. That will make our profit increased again.

But… the crab around here are gigantic. Most of them are over one meter in length. And I think I saw some more bigger than three meters.

Are they difficult to fight? Let's try them. I don't think they are harder to fight than those killer dolphins.

I provoked one of the crabs to come out of hiding, and the whole lot of them come out! Well, seeing how they move, I don't think they are faster than those killer dolphins.

They are approaching me at the same time. Prove that they are not a smart species. I guess I'm right that they are weaker than killer dolphins.

I easily dodged their attack, and with Victoria as a broadsword, I slashed one of the crabs.

It's hard!

Even when I'm using my Aura covering Victoria, these crabs have really hard shells! Not as hard as Giant Salamander that I killed, but it's' still hard enough for my weapon covered with Aura to breakthrough.

I don't think I can use that drill like I did with the Giant Salamander well underwater. I guess my only options is to continue attacking them until they die. This should be good as well for my Aura training.

I attacked the same crab again and again with the broadsword. In the first place, I chose the broadsword as a weapon because of its usefulness in continuous attack underwater by following the current. And this is the first time I use it for that purpose since all the other of my underwater fights are done with just one attack.

I keep slashing the crab over and over again without ever stopping my arm. There are already scratches on the shell of the crab I fought. Then when the crab about to attack me with its claw/pincer, I transformed Victoria into a shield to block it.

Another thing I did not expect, is that the crab's attack is stronger than I thought. And since I have no proper footing underwater, I got pushed back easily.

Good thing that I still managed to block the attack. Now I know that I have too many weaknesses in underwater fights. It's a good time for me to fix them.

If I have a terrible footing, then let's use the water as footings.

When the crab attacked me again, I put Victoshield in front of me to guard, and also cover my whole body with Aura. With the water pressure while covering my whole body with Aura, it makes it harder for me to move. But it's a good idea only for blocking attacks as I haven't moved back when the crab's pincer smashed my Victoshield.

But there's a delay after I blocked the attack, and when I'm about to attack since my Aura also stopped me from moving. I need to practice more so I can control my Aura even smoother so I could reduce the delay.

Then I repeated my actions. Attacking the crab continuously, then blocking its attack. I feel the control over my Aura is getting better and smoother, but I can't do that for long since there are a lot of crabs here.

When I was about to attack the crab again, I noticed that another crab won't sit still and attacked me from the side. My reaction is fast enough to block it, but I haven't covered my body with Aura. That's why I got pushed away from the first crab that tried to attack me again as it missed its swing.

Maybe it's a good idea to get pushed back some time. I can get away from being surrounded that way.

There's a reason why I wanted to improve so badly. Of course mainly is that I want to get stronger and better in fighting. But other reason is… I saw an underwater dungeon nearby.

Unlike the previous dungeon which only has the underwater part at the entrance, where the eels are delicious, this time, the whole dungeon are completely underwater.

And it doesn't seem like this dungeon was sunken. This dungeon seems to have been there ever since it was created. It's totally an underwater dungeon.

But the monsters that I see with my Divine Vision, might be even stronger and smarter than the killer dolphins. And I haven't seen everything yet.

Since it's a dungeon, there might be traps hidden there. That's why I need to improve my swimming and battling technique. Although I have my Divine Vision helping, there might be some traps I will get caught on.

When I told Victoria about the dungeon, she said to let her in that dungeon so she can scout there first before I enter. It's so great to have an immortal summoned monster.

Fighting underwater is still difficult for me to do. Even after I slashed dozens of times at the same position, the crab's shell is still difficult to penetrate.

Maybe there are other parts which are easier to hit to kill the crab, but this is also for my development as well. I have to find a way to be able to break through their hard shell. Because unlike that time with the Giant Lizard, it's unlikely that I will encounter other monsters that won't move when I drilled through their defense.

This time, I stopped attacking the crab's body and went for its legs. Although they are covered by hard shells as well, that part should be easier to damage.

And after ten hits, I managed to break one of its legs.

I keep doing that to its other legs, and also to other crabs. After that, I broke their pincers. As for their bodies… I don't think I can destroy them when I'm underwater, so I brought them to the surface, and kill them there… not.

Just killed one of them so I know that it works, and brought the rest home to be cooked. Although they don't have legs or pincers anymore, their bodies should still be delicious.

They are big, so I only brought home two of them, and some seashells in the empty island. As for the rest of the crabs, I think they will be eaten by other sea monsters. I don't think they will still alive by the time I return here tomorrow.

And so, I returned home with big catches.

When I arrived home, I instantly went to the kitchen where Lina is and brought them the giant crabs.

"Sorry. They are too though so I have to destroy their legs and pincers before I can bring them home."

"Don't worry. If They are similar to normal crabs, then their bodies would still be delicious if I cook them right. Please wait for dinner."

I helped Lina carries the two crab's bodies that she will cook for tonight. I can't wait for dinner.

As I was about to take a bath, I see someone knocking on the door. There are no other people here since everyone is doing their own training and cultivating, so I'm the only one here. I don't like greeting guests since I might forget them right away, but I have no choice since I'm the only one there. And I don't think it's right to let a slime do it for me. I don't know what form Victoria will be when she opened the door since she's very unique.

I used my Divine Vision to see who the guest is, and I think she's somewhat familiar. I guess I forgot about her.

I opened the door and see the girl happily smiled at me.

"Master! I have returned and hoped to get your guidance."

"…who are you?"

"HOW COULD YOU FORGET ABOUT ME! YOU'RE SO CRUEL, MASTER!"

"Ah! You're the loud girl!" I said as I finally remember who she is.

"YOU'RE THE ONE WHO SAID THAT I HAVE TO KEEP MY VOICE DOWN! YOU CAN'T JUST FORGET ABOUT ME WHEN I SPEAK NORMALLY!"

"I know, I know. Sorry about that. You can lower your voice again now."

"NOT YET! I HAVE TO ADJUST MY VOICE FOR A FEW MINUTES SO I CAN HAVE MY VOICE LOWERED!"

There's a strange species entered my house. She's so loud and can't adjust the volume of her voice easily. So, I let her in because she will bother the neighbors if she continues talking like that outside.
