What is most necessary for a person to live?

It's water. Water that sweats and runs off. Water that becomes urine and is excreted. Water mixed with exhalation and evaporating. A person's body is able to actively drain moisture, even if he was thirsty to the extreme.

So people, above all, must consume water. You only have to take in the moisture for what's been drained.

People die faster than hunger, with thirst. Some have accomplished weeks of fasting with water alone, but none have accomplished the same feat with dry goods alone.

Nearly 60% of its body is made up of moisture. It is only natural to think carefully that, first and foremost, you will die if you do not drink water.

"That's why we're going to rehydrate -"

"Ooh!

Guido, a former adventurer, also well understood the importance of water.

In Earth, a medieval world, water was difficult to obtain anyway. There is no mineral water, enclosed in a pet bottle, that will last a year or two, or tap water that will come out if you twist the faucet. All there is is is spring water and well water, and 'where water suitable for drinking can be drunk' itself was much less than in Japan.

When I was not yet familiar with "Earth", I had neglected to replenish drinking water and was about to become dehydrated in the middle of the street. From those bitter experiences, Guitar still carries ten litres of bottled water, always in a personal storage space.

I'm surprised that even this much water, when I think of it as a necessary amount for the human body, can only be used for five days. Even if I chopped it up and drank it, I wouldn't mow it for two weeks. Just do what you can, and your body starts complaining about the malaise.

Your Highness continues to talk about these waters as you circle the outer perimeter of the island.

"Ah, Doctor, it's a river!

"Oh, there it is. Then let's go upstream."

"Huh? Can't it be river water? From what I've seen, it looks like clear water..."

Boy students who were packing porn books into storage spaces instead of water complained sooner which thirst.

He stares at the sarcastic flowing fresh stream and looks like he's going to want something.

"You can't because the seawater is mixed. Besides, it's beautiful, but when you get this far downstream, there's fine sand and mud floating around. There are demons and animals dropping by the water, so the faeces and urine may be dripping. That's why people with poor stomach and intestines have to go upstream. OK?"

"Salt and sand yet. I don't like faecal urine, faecal urine... haha"

The bitterly laughing boy student left the creek leading to the sea and continued after a noble university aiming upstream.

The island they adrift has a distorted oval shape when viewed overlooking. At its centre stood the mountains covered with trees, surrounded by forests.

Would the radius of the island be about 2 km vertically and 3 km horizontally? Greens flourished deeply in proportion to the area, and when it came to going upstream, they didn't want to walk in the city.

A leading noble university pays for spreads and branches with a knife, followed by students widening the path and consolidating their steps. A line departing from the west coast takes you on a sort of slope towards the centre of the island.

When the sun, which began to climb from the eastern sky, fell upon Jomtien, Guitar finally stopped. On the coastline, the river, which was wide enough to have spread its hands, was thin enough to be gripped with its hands.

"It's time, okay? All right, you guys, if it's water around here, you can drink it."

Students who boil down to your words and whisk up fresh water with their hands.

The spring water coming out of the sand was as sweet as sweet as sweet dew on my thirsty throat, and I could drink as much as I wanted, even if I wasn't willing to.

"Spring water is so delicious, Doctor. I think I'm going through the mountains for this flavor craving."

"No, no, no, no matter how much spring water, there's something you can drink and you shouldn't drink. If the soil is contaminated, if you drink spring water, you'll go belly down."

"What!? So, what about this one here...?

"You're gonna be fine here. Because,"

"Because fresh water flowers are blooming, right, Doctor?

It was Camilla, your girl, who broke into the conversation with the girl student.

She grinned, stroking a white, little flower that was blooming near the source of the water.

"Oh, you know me well. Yes, if this white one is in bloom, it means you can drink the water there. I hear these flowers are sensitive to pollution. No matter how beautiful it looks, it never blooms where the poisonous water is gushing. You guys in urban life won't have much chance of being taken care of, but, well, remember."

"Yes!"

The students nodded loudly, carving small, poor flowers into their hearts.

After enough, the students, who had finished hydrating and filled empty bottles and empty containers with water, were turning back the way they came.

"Until help comes, it's a repeat of this every morning. Draw water to use in a day and return to base. Even the adventurers were dying prematurely. Don't neglect to secure the water and keep the water in place, okay?

"Yes, Doctor!

We paved even, so we followed a path that made it somewhat easier for us to get through, and the greats walk in the woods.

The students' faces are bright knowing where fresh water springs up and convinced that only water can drink as much as they want. But one relief is that it is the shipwreck who will come out with the next anxiety, and the nobility of the puller was well aware of that.

"Nevertheless, if you don't eat rice, you still have the strength. And so, now we secure food."

"Whoa!"

Exciting boys students. As a matter of fact, in their childhood, in the upper classes there was a popular picture book that became 'South Sea Adventure Tan', and many admired the secret for the situations in which the protagonist picked pannoki fruits and baked and eaten them with wild birds.

"Doctor, actually, I was confident in my hunting skills."

"I've had three deer in a day. This is the bow of the family heirloom I gave away from my father."

Boys students who confidently ring a bow string slightly.

Some of the old ladies are also taking a stunning matching bow out of their personal containment space and smiling.

I feel completely, the hunter himself. Where did they feel frightened by the shipwreck, and they were familiar with and enjoying the situation as early as possible.

I call that alarming, but your university sighed briefly, and took the survival knife out of my nostalgia.

"Well, let's hunt -"

"Yes!"

"Fruit."

"Yes!... Huh?

Guitar jumped up big with his jumping skills [high jump] and shook a knife in his right hand to the side.

Landing, the knife is wrapped around the sheath, and your hands are spread out as if they were frightened. On its hands, fruits like oranges fell bottomwise.

Guitar spoke to the students as they peeled with their hands and threw the pulp wrapped in the bag into their mouths.

"Look, you're hungry. That one, get it."

(... not to be blatant!!

The students, who just thought they were going to hunt the beast, dropped their shoulders disappointed by the unexpected situation and unfortunately lost their bows and arrows.

"Oh, you can eat this, too. Look, you can eat this grass raw."

Precious magnitude that grabs the stems of seri-like plants that grow along the fresh stream and progresses steadily.

Behind him, the students with their ghostly sunken expressions walked around, clutching stems inorganically.

"Hmm, there's nothing more edible than I thought, this forest. If there's enough vitamins, there's nothing we can do about it."

A line that went on for a while while while collecting grass, fruit, nuts, etc., had stopped for once at the midpoint between the stronghold and the water resources.

Noble Dae, who spread his harvest in an open place in the woods, put his arms together and roar, yeah, yeah.

"I think I'll expand my exploration a little bit. Uh, but if a student gets lost, I'm in trouble. I'd be scared if I had a unique monster. Melissa and I will explore the whole island for once..."

"Did you call?

"Whoa!? Melissa ah!?"

Everyone on the spot jumped and was surprised by the light peachy Sister, who glimpsed his face from the shade of the woods.

Dressed in a light peach piece woven with a small gold cross pattern, Melissa pampers her sandals of the same colour and approaches the precious.

I remember the impression that the presence that appeared without even making me feel the slightest signs of dust was the girl who laughed innocently, etc., and the students shook their bodies for the first time.

Meanwhile, noble daughters, who were just as surprised as they were, were recovering lightly because they knew the power of Melissa, who could even make a space transfer on her own, "Don't surprise the general people," she said, lightly poking Sister in the head.

"Eh, I'm sorry. But Takahiro seemed like a pinch, so I rushed here. Takahiro, what are you in trouble for?

The tanned Melissa puts her hands behind her back for a naive smile.

"Hmm? Oh, I don't have more fruit or anything than I thought, this island. Nutrition, I wonder if it's enough."

Sitting on the ground, Guido had slightly creased between his brows as he showed Melissa the fruits and nuts he had harvested and the young leaves and stems of the plants.

Two people, no, maybe ten, wouldn't have had to think so hard about food. But there are too many thirty people on the island without knowing when the rescue will come.

In the critical situation of distress, the more food there was, the better.

"Huh? What food... you can eat this and this?

The edible plant, the noble one moaning about the lack of fruit, let Melissa answer blatantly.

The thin peachy Sister, picking the tulip-like red flowers that were blooming nearby and the small grains of black fruit that were growing into branches, offered them dearly.

"Oh, did you eat that?

"Yeah, I can eat it. I can eat that and that, and that's okay."

"What!? Oh, seriously."

Melissa stretches her fingers all over the square of the woods where you were resting small.

In his time as an adventurer, Noble Daughter, who had deepened his knowledge of edible wild grass, had a good deal of confidence in his ability to survive.

But the world is wide, and that means he was just a frog in the well. Still, to Melissa, who pointed to "What You Can Eat," you raised your hands and indicated your intention to defeat.

"Even so, it's a treasure trove of food, this island. There's plenty to eat. I'm never going to be able to eat these still colored purple mushrooms or anything, but I can. Hey, Melissa. Are you gonna bake and eat this?

"Yeah, we eat it raw. Not if you bake it."

"Raw... Me, I've never eaten mushrooms raw, but I don't think I'm going to have a belly break... hey Melissa. Are you sure you don't want to bake this mushroom?

"Yeah, you can't if you bake it. If you set fire to it, the chaser will find you."

"Huh?"

Here at last, Guitar University realized. "What you can eat" is too much.

Melissa even pointed to the famous poison mushroom that even children know and said, "I can eat it. Eat raw," he says. From Melissa's eyes the light was lost and the dark atmosphere began to drift around her.

"There's nothing you can't eat in this world. Even if you break your stomach, you'll be fine because there's a cure. But not if you pick too much. You can't leave a footprint. Absolutely no burning. If you leave a trail, the scary ones will come. Once you realize it, as many of you will come. So don't like or dislike anything, eat raw. If I break my stomach, the spell of healing. If I break my stomach, the spell of healing. If I break my stomach, I'll be cured..."

"Go back! But come back, Highlights!

With a dark grin on his face, the students were shaking his legs like a newborn deer before Sister, who kept squirming in vain.
