And so, a week has passed since my negotiation with Sam.

That day, after concluding our negotiation, I left to check the rival group. Luckily, the first group I checked has no member of the cult. It was Sam's group biggest rival so it won't be strange if Sammy died because of that group.

After telling Sam that night, she told me that she will take care of it. Seeing how she preserved Sammy in ice, it might be a while until she planned out everything. But I will trust her in how she will do it.

Funnily, when I got to Sam's base that night, a parfait already waiting for me to eat. And a maid already waiting for my praise. When I told Lina I will come after I got the goods, she looked dejected.

Aaah! I want to praise her every day!

I went back to the brothel telling the girls' debt are cleared. The brothel closed again that night. And it hasn't been opened since the girls are focused to be stronger so they can be a hunter instead of sex worker again.

When I told Ruby about my negotiation with her daughter, she told me that she built this brothel so the girls who fall into debt can pay their debt little by little. So when the debts are cleared, she found no reason to continue her business. Now it looked like this brothel changed into magic school since everyone were so enthusiastic.

Some of the girls also has rare magic which hard to find. Like Sophie's lightning element. If only she had enough resources, she would be able to pay her debt by doing some quests.

Although we still don't have enough resources, at least I can teach everyone to improve without using resources. Of course I only told them what Victoria told me.

The day after my negotiation with Sam, I went to Angela's and Kayla's new apartment and tutor them for the exam. Other than some magic theories, the exam include math, history, and language. Language is obvious because not many people can read, so if the student want to go to college, they must be able to read and write. Math is necessary to not be swindled when shopping, and history is so everyone knows common knowledge of the past. As for geography, somehow it wasn't taught in the first place so it's not included in the exam.

For the people in this time, they don't need to know the location of another country. As long as they know their city, the cities surrounding, and where the capital is, they will be fine. It was until about 20 years later that geography was taught in school so people will know the boundary between countries. At least that's what I've heard.

Anyway, the test was finished and we all passed. Since this is my second life, I can pass easily. Kayla is smart enough that even if I didn't tutor her, she would be fine on her own. As for Angela, she barely pass the exam. She found it difficult to study anything not related to magic.

Well, that's all for the written exam. Next is magic exam.

For those who wanted to learn other things than magic, like how I aim to be a doctor, magic exam won't change the result for the exam. But if you do it well, you might get a recommendation to an elite college for magic and get magic resources and scholarship.

This magic exam wasn't important. There are three exams in one year so the most important one is the third exam since that's where the students is at their strongest point in their student days. And after that last exam, there will be another sparring event like last month, but there might be scouts in the audience to offer the students recommendation to their schools.

I told that to the girls and they choose to hold back during this time. They each showing their weakest magic. Angela used her wind magic and Kayla used her Light magic.

As for me…

"Summon! Black Slime, Blobby!"

The teachers not making any changes in their expression after I summoned Blobby. That's all I needed to show as summoner. Since the strength of summoner can only be shown by how strong their summons are, so when I summoned Blobby, the teacher already made their judgment.

Then one of the teacher asked me a question.

"Why is the name of your monster is 'Blobby'?"

"Because she's a blob. Another option is Blimey."

"Alright, next!"

What? Nothing else? He's just ask me about the origin of Blobby's name? He doesn't want to ask why Blimey? Blimey!

In any case, my grade is already decided by the teacher. At least they know that it's useless to recommend me to magic college. At least with my grade, they encourage me to go to medical college when I told them that's what I'm aiming for.

And so, the time has come for me to leave this city again.

"So? Where are you going?"

Kayla and Angela are curious about my destination. But seems like Kayla already had a guess.

"Cassau city."

"Cassau? You're going to the sea?"

"As expected of you. I already guessed what you're going to do."

Angela doesn't know what my goal is, but Kayla already guessed it.

Kayla knows because Cassau is a city next to a sea. It's also where most trade happened since it's where the harbor is and the destination of merchant from other countries who's doing business in our kingdom, Tatrama Kingdom.

I feel like this is the very first time I thought of the name of this kingdom since I turned back in time.

"Kayla, you know about it?"

"I don't know his destination is, but I can guess what he's going to do."

"And that is…"

""He's (I'm) going fishing.""

Both of us answered at the same time.

"What?"

And of course Angela is curious why I'm going fishing in another city.

"Do you remember that I had just get a partnership with someone?"

"If I'm not wrong, your partner is a mafia or something."

"Right. But after this mission on Cassau, I bet they will choose to be merchant since it's very profiting."

"You're going to trade fish?"

"Possibly, and also all other things that lay in the bottom of the sea."

"Since he can breathe underwater, he's going treasure hunting under the sea, where no one has ever tried to before. Not just because it's hard to find mage that can fight underwater, but also because of the monsters there. Most of the monsters under the sea are still unknown to us. We can learn from books and hearsay about shark-type monster, siren, and other well-known monsters, but it is presumably only less than 1% of what's hidden under the sea. It is an unknown territory."

Kayla kindly explained to Angela.

"What?! Why are we going there if the monsters are unknown?"

"What? You're thinking of coming along?"

"Huh?"

Huh? Angela seems to think that she will come along. Why does she think that?

"It is a totally unknown territory, so I don't suggest you to come along. In the first place, I want to go there alone. With Blobby/Victoria."

"Eh? Then what will I do?"

"You and Kayla can choose to do some quests like usual and improve your rank. And I'm asking you to teach the girls in Red Tail about being a hunter."

"Sure. I can do that."

It was Kayla who answered.

"Well… I can do that too. But I'm worried about you since you said that it's a totally unknown territory."

"Oh? You're worried about me? Don't tell me that you have fallen for me?"

"No. You can leave. I will help the girls from Red Tail."

Her attitude changes too quickly. Does it mean there's no chance for her to like me? Well, that doesn't matter since I already have Kayla.

"But are you sure you can find treasure at the bottom of the sea?"

"Yes. Think about it. Most trade to far places, are transported by ships. And even though we already have a safe sea route, it took us hundreds of years to finally found it. Before that, there are already many ships sunk because of monsters. Even today, although we have a safe routes, it doesn't mean monsters won't attack. It's just a route where monsters are less likely to appear.

And so, where are the goods carried by the ships? They're at the bottom of the sea. Other than that, there must be another treasure I can get there."

"What treasure?"

"Resources. Since it's at the bottom of the sea, there should be magic resources for ice element. Then if I find underwater volcano, there might be another one for fire element. As for earth, maybe they are buried in a cave underwater. Ice, if I go to a place close to iceberg. There might be other, but that's the obvious ones. Many researchers already thought about it, but since the places they are located is difficult to reach, no one has ever tried it. But what about me? I have Air element that makes me able to breathe anywhere, Blobby who can change into any shape I want, my vision that can see through the darkness, and my Aura ability. Since if I trained Aura I could walk on air, what about underwater? Especially when water is much thicker than air. My Aura and Air element should be able to make me move well even underwater. So this is an experiment for me."

"You're risking your life for an experiment?"

"You should know it by now that I won't risk my life. If I can't do it, I would just give up. That's all."

"Roy. You forgot one thing. Underwater ruins."

"That's right! If I could find one, I can be rich in one day!"

Thanks to Kayla reminder, now I have one more thing to look forward.

After that, I return to Red Tail and tell everyone I'm leaving to Cassau. I also told the girls that they can learn from Angela and Kayla when I leave. Daniel about to cry when he realize I'm leaving again, but after I told him it won't be as long as before, he calmed down.

That night, he hugged me tight in his sleep.
