Then a little later.

We were reaching the center of the sixth source without being disturbed.

"Right here."

'This is the heart of the source… it's amazing size…. I can't see the bottom......'

In the heart of the source is an artificial lake called the 'Central Reservoir Lake'.

It has a diameter of about 500 meters and a water depth of about 2000 meters.

At the bottom of this huge reservoir lake is installed a magic device that produces a huge amount of water.

One man sat down by such a lake.

- He was carrying an example poison, a masked man.

Beside it is placed a bag of poison that the man was carrying.

The bag reads: 'Special disinfectants. Wearing protective masks when in use'.

Apparently the example poison is disguised as a disinfectant for water supply.

Well, that's an extremely natural option as a camouflage.

If it's disinfectant, it's not strange to have it in the water hospital warehouse, and it's not suspected of putting it in the source.

Normal disinfectants are also toxic to kill fungi, so it would also be a reason to put on a protective magic mask.

The masked man looked at the hourglass, beside a bag filled with such poison.

Apparently, there's a set time for the poison to be put in.

'... you just have to stop him.... There doesn't seem to be defensive magic or anything, can I bow it?

'No, a bow threatens to catch detection.... This reservoir, if you look closely, is full of detecting demons.'

That's what I'm referring to nearby ground.

There was a type of demonic prop placed there that sensed airflow.

The airflow sensing type trap has the disadvantage that if the wind blows at all, it will malfunction.

As a result, the outdoors are useless, as well as in places where people come and go.

But because it's so sensitive, it's hard to deceive.

If you disturb the ambient airflow at all, it will react quickly.

It doesn't translate to magic props for magic sensing, which can be deceived by simply turning off magic.

This reservoir lake was heavily equipped with such 'detective magic tools that can be used because there are no people in or out of it'.

Naturally, land is full of traps, and because there are such magic items up to the inside of the lake, there's no way that it's safe to walk with boundaries on top of the lake.

We're not caught up in detection right now because only the entrance and exit portions of the aisle are equipped with detective magic props in the shores of the Central Water Reservoir Lake.

Probably to avoid malfunction.

I don't know what happens when you get caught up in a detective magic prop, just by looking at it... first of all, no doubt, it won't be a loco thing.

If you try to be an enemy, you don't mind blowing up the reservoir with a whole massive explosion magic if someone gets to detect it.

In that case, the poison delivery clerk won't be safe for the first time... but he's not the one who seems to care about that either.

'Wow. That sounds like a troublesome detection... Can you get over there without finding out?

'Proceed with care and we'll figure it out.... wait here for me'

That said, I magically erase my presence and approach the man with care not to get caught up in the magic props.

Along the way...... the masked man moved.

Nothing. I don't see how you noticed my movements.

The man's gaze was poured into the hourglass at hand.

Just, I guess it's time to put the poison in.

"He's moving!

'Keep it up, there's poison in the lake!

"Oh. You're not gonna make it."

With that said, I will proceed with caution to avoid getting caught up in the Detective Demon Prop.

Nothing. You don't have to stop poisoning me.

'Er... don't you want me to stop you?

"It takes about three hours for the reservoir to be poisoned before that water runs out. You can process it in the meantime.... I just left this water alone in the first place, and things won't be the same until yesterday '

'Oh, well. The water in this country should have been poisoned a long time ago, but people in this country usually seemed fine.'

'That's what I'm talking about.... Well, it looks like the person who spreads the poison doesn't either'

That's what I see, a masked man poisoned the lake.

The masked man fluttered, clearing out the bag he had used to put the poison in with his blue and white face.

Obviously, it lacks vitality.

With a mask that only covers your face, there's no way you can completely prevent poison.

Already the masked man seems to have been sucked into life by high concentrations of poison and has lost strength.

... Now, it's not weird when you fall.

If you look closely, there were numerous bloodstains around the man.

Perhaps there has ever been a similar masked man here.

And he fell right after he spilled the poison.

As I proceeded with that in mind, I reached near the masked man.

There are no detective magic props around a man, and it's easy to kill a man as he is... but he may have some information, and unlike a doll, this man feels like he's just being deceived.

... In the meantime, should I leave you to pass out?

With that in mind, I stunned a man by typing in simple magic.

On the fall, a man groaned every wow.

'I... have to protect the water supply... if I don't do it, there will be plagues all over the country...'

Apparently, the masked man was just a work enthusiastic water steward.

The vitality seems to be quite sharpened, but the man seemed to have worked out quite a bit originally, with high basic health.

If it feels like this, you won't die leaving it alone.

'All right, let's make sure it's safe elsewhere, and then we'll open up an example stash. When you open a hidden room, it's the worst pattern of being pinched.'

Having stunned the masked man before returning to the Luriis, I say so and turn back the way I came.

I know the enemy is in a hidden room connected to an outside warehouse, but it sucks when there are demons hiding elsewhere and they get pinched.

To prevent it, let's start by making sure it's safe from the visible areas.
