city at the bottom of the lake?”


“Then, I will cast a magic spell to avoid getting attacked by monsters.
Just for your information, the entrance to the lakebed city is at a depth of about 300 meters.”

“Thank you!”

A kind of blurred aura was attached to me.  Avoiding monsters, I’m just going with the flow, but then I suddenly realized something.

“It’s kind of too late now, but I have the title [Friend of the Water Dragon], so I don’t need this magic..”

“Well…… no, I mean.
It’s a bit of a cheat, and there’s a proficiency issue anyway, so it didn’t hurt to take it, yup.”

Right now I’m in the area that is said to be closest to the lake bottom city, still, I felt like I did something meaningless and wasteful, even though monster-repellant magic was free.

I jumped into the lake from the edge of the pier and after diving a little, I tried to find the lake bottom city to aim for.
There, I saw a faint light from a group of buildings at the bottom of the lake.

“I was diving towards the bottom of the lake for 130 seconds, since my speed is about 3 meters per second, I should be around 300 meters deep now.
But it appears that it’s not exactly located directly below us, camera, show them what’s in the water.”

“It’s probably that one.
It’s hard to measure underwater, but it’s probably about 400 meters away.”

The location is not directly below this pier, but diagonally below it.
It is just at the end of the diagonal of the square.

“I’ll just go for now!”

I breathe in without any meaningful reason and then dive in one breath.

As I swam diagonally towards the lake’s bottom ruined city, I soon realized that I had made a mistake.

(This angle, I must have been shifty….
and I meant both in terms of distance and efficiency.
Ummm, diving is really something I’m inexperienced at.)

The force was subtle, it’s coming both from above and below, and it felt like I couldn’t dive as smoothly and deeply as I wanted to.

After about a minute and a half of diving, I kept moving my legs, thinking that no matter how hard I tried, I couldn’t reach the surface… but my diving skills ran out when I only need 20 meters to go.

Once this happened, there was nothing more I could do.
The cost of diving without diving skills is that I lost my SP, and next to SP, my HP.

Not long after, I was resurrected at the Adventurers’ Guild in Trillia.

I got the death penalty, but at least now I know that diving skill as a passive skill doesn’t affect your swimming speed by much.

“ughh… I ran out SP… but considering I did it without plan that was already pretty good.”

“Scary? fufu, my vision was not that different from the ground.”

I’m starting to calm down.
And no, I’m not getting any more proficiency, by the way.
I’m not sure if it’s because I’m avoiding demons or what.
Well, it’s called challenge for something, I guess.”

I thought that after diving for two and a half minutes, one of my proficiency levels would have increased, but it didn’t seem to be the case.

Maybe it’s treated as an event, and it’s not supposed to go up with this challenge.
It’s a little stingy, isn’t it?

“When I think about it calmly, diving at an angle is a huge waste of time.
You need to think about gravity, it is definitely faster to dive directly down.
And it takes more time to move sideways.
So I’m thinking of swimming quickly to the surface and then diving down.”

{implying she is muscle brained}

“I do think, you know!”

If you look at the sides of a square and the diagonals, the diagonals are longer.
I think it’s the one that says, let’s see, √2 times the diagonal.

I know it’s a very obvious thing, but if the pier is set up like that, you would think that you are supposed to swim from the pier, wouldn’t you?

No matter how you think about it, it would be more efficient to dive from right above the city at the bottom of the lake all at once, but since all the players are swimming diagonally from the pier, and by now, they are probably guided by the same thought process.

Even so, I wasn’t sure if I should do it, so I decided to ask an NPC who put a monster repellant magic on me.

“Is it okay if I swim straight up first?’

The monster repellant spell lasts for five minutes, so you can do it any way you want within that time.”

“Thank you very much.”

As expected, they didn’t give me any strange stare at all but rather gave me their approval as if it was a matter of course.

<↑ Does this mean there are many players who are trying to conquer this with their own style somehow? >

“I think it’s fun to explore by yourself, isn’t it? Okay, let’s swim to the top of the city at the bottom of the lake first, and then dive all the way down!”

<↑This is not sea btw.>

I took two minutes to swim above the top of the city at the bottom of the lake, and then I started to dive toward the city after I fired up my spirit, hoping I could reach it this time.
