Adventure Guide No. 5: Caves are not prone to fire, burning consumes a lot of oxygen and may produce thick smoke, causing adventurers to suffocate.

*********************

It was already 4 o'clock in the morning when Sora woke up, probably because he had spent too much mental and physical strength to get out of danger, and he slept for 10 hours this night.

Nana should have woken up a long time ago, but she didn't leave her master's embrace. Sora saw that even in her arms, her two long ears were raised high, vigilantly sensing her surroundings to prevent any wild elf from harming him.

"Thank you~ vigil for me." Sora whispered in Nana's ear.

"Babble~" Eevee pecked his master's face to show intimacy.

Sora took the clothes that were hanging on the side before going to bed and touched them, they were not dry, but they were much better than yesterday's wet and wet conditions.

He put on his clothes haphazardly and took a look around. His eyes had grown accustomed to the darkness, and he had noticed that there were glowing plants growing here on the rock walls, some of them resembling moss, and some of them had thick leaves, much like aloe vera that had never been seen before. He broke off a leaf, and the juice trickled from the cut to the ground, and the ground fluoresced.

It turns out that the fluorescent substance is in its tissue fluid, and it is empty. Then he saw Nana leaning over and sniffing, and he didn't show a disgusted expression, he smelled it himself, what about the smell of grass, maybe it was non-toxic? After all, I still didn't dare to taste it, and food poisoning in this kind of place is no joke.

Since there are other light sources, the flashlight should be kept first, there are a total of three batteries, and it should be no problem to use it for 3 days. The green hat light on the head is always on, its power is very low, and the light emitted is relatively dim, and it can be used for a long time. But if given a choice, Sora really doesn't want to wear it on his head all the time.

Before leaving here, Sora filled all the water bladders on his body, and although he already knew that there was a dark river underground, it was hard to guarantee that he would be able to encounter its tributaries in the future.

"Let's go, Nana." Sora greeted Eevee, chose a direction and began to move forward. He has basically determined that his location should not be out of the range of the second underground floor, as long as he walks to the southwest and high ground, he can be saved, and no matter how bad it is, he can find some traces of human activity.

Nana consciously ran to the front of the empty space to find the way for her master.

The two figures slowly disappeared into the darkness, drifting away.

……

This walk took 6 hours.

It's not a pleasant experience to grope your way through the darkness, the endless darkness, the occasional sound from the depths of the tunnel, which amplifies every trace of negativity in your mind, worry, confusion, loneliness, and fear of the unknown.

But as long as Sora sees Nana in front of him, he will feel at ease, and all kinds of distracting thoughts will recede like a tide, leaving only the desire for life.

Fortunately, with you by my side, I was not swallowed up by the darkness.

Eevee also walked cautiously, and the elves would be afraid, and they would be afraid, but ......

As long as I'm by your side, I can overcome anything.

Unconsciously, the two hearts are closer.

During the period, I did find a lot of mushrooms of different shapes, whether they were poisonous or not, they were all collected, and they were carefully inspected when they encountered a place with a water source. Many of the mushrooms are spore-reproductive, and Mt. Tsukimi has a colony of pyras, which may have been spilled while walking in caves.

In fact, Sora has met this kind of elf many times on the road, it looks like a cicada larva, with two small mushrooms on its back, it is very timid and cautious, and it will hide when the wind blows. Pyras is actually a very sad elf, who has been controlled by the plants on his back since birth, and after evolution, even his self-consciousness has completely disappeared, and he is completely dominated by plants. In addition, another name for this elf is Cordyceps...... It is said that the plant has a very high health value and is sold at a high price in the market.

Before Paist evolved, if the mushroom on his back was removed, he would not die, but he would never be able to evolve into Palast. But maybe that's a good thing for it.

On the way, I also encountered a lot of small fist stones, pangolins, gophers, and even rumbling stones have been seen twice. There are those who don't want to be killed, but they have all been taught to be elves by Nana with a [shadow ball]. Sora found that the [Shadow Ball] was so easy to use in the dark, silent, and powerful, and it didn't need a second trick to deal with this kind of wild elf without a trainer.

But what makes Sora strange is that he doesn't know why he hasn't encountered the Great Rock Serpent yet. The underground world of Yuejian Mountain is so accessible in all directions, it is all due to it, there is no reason why you have not seen a single one after walking for so long. The large rock snake generally lives in the mountains or underground and feeds on rocks, so it has a gentle personality and has no quarrel with the world. Even the ordinary large rock snake is 10 meters long, and some super huge large rock snakes that have lived for a long time and have undergone metamorphosis have been found in various regions, or their subspecies crystal large rock snakes, obsidian large rock snakes, etc.

Although the reason is not clear, Sora instinctively deduces that it may be related to the strangeness of Tsukimiyama.

Just as he was thinking, there was the sound of running water in front of him, and Sora quickened his pace.

In a few moments, he found the source of the sound of running water, a mountain spring gushing out of the rock wall, which flowed down the rock wall to the ground, and finally seeped into the earth, and behind the rock wall was probably a river channel.

Sora's previous speculation was correct, that dark river really has many tributaries, so there is no need to worry about drinking water now.

After walking for so long in one breath, both Sora and Nana felt a little tired. Sora decided to take a break here and grab a bite to eat.

You can't easily light a fire in a cave, and this is naturally clear. But there is not much emergency food, and when you don't know when you will be saved, of course, you can save it.

Just because you can't start a fire doesn't mean you can't heat food.

There is a sealed bag in the hiking bag, which contains many heating packs and salt packets. This is also prepared by Kamio's father for the air, as an old driver who survives in the wild, taking his son out on an adventure is naturally to take into account everything that can be taken into account.

Once again, I would like to thank my thoughtful father. Take out one of the heating packets and one of the salt packets, and start looking for stones. Fortunately, now underground, stones are quite common. I picked a piece of the right size, and then called Nana.

"Nana, aim at the center of the stone and use the Shadow Ball. Control the force and don't break the rock. Sora commanded.

Nana was very smart, and immediately understood what her master meant, and condensed a small [shadow ball] from the tail and printed it on the stone. The corrosive energy quickly carved a large hole in it, and it felt almost there, and the void made Nana stop.

The size is just right, and I am very satisfied with the size of the stone bowl. He then rinsed the stone crumbs from the bowl with clean water and set it aside. He and Nana had picked a lot of mushrooms along the way, and it was perfect to take them out and sort them for lunch now.

Relying on the method taught by his father, Sora quickly picked out the mushrooms that could be eaten, and the poisonous mushrooms and some mushrooms of unknown species were thrown aside. Still not at ease after sorting the empty mushrooms, she asked Nana to smell the edible mushrooms one by one, and then take them to clean after she nodded. In any case, the elves' sense of smell is far superior to that of humans, and Nana should be able to distinguish some of the toxins hidden in the mushrooms.

While cleaning the mushrooms, Sora had already put water in a stone bowl and threw it into the heating pack. This kind of heating pack is very practical, it can immediately heat up within 3~5 seconds after contact with water, and the maximum temperature can reach 150°C, which can easily boil water. The most important thing is that there is no smoke generated during the heating process, only a little water vapor, and it is very environmentally friendly.

Of course, the mushrooms can't be thrown in and cooked, so take out the stainless steel lunch box in the backpack, fill it with water, put it in a stone bowl, use the water temperature on the outside to boil the water in the lunch box, and then throw in the mushrooms and a small piece of compressed biscuits. Finally, tear open the salt packet and sprinkle a little into it. A steaming bowl of mushroom soup is ready.

I scooped up a spoonful and tasted it, it seemed a little too light. I simply poured in the remaining half packet of salt, stirred it, and tasted it again, this time it tasted just right.

The heating pack works for a long time, and I can't think of a way to get out the hot lunch box for a while. But he couldn't help but sigh when he saw Nana on the side eager to try it and couldn't wait to try it.

Then, he carefully scooped up a spoonful, put it to his mouth, blew it, and when it was a little cooler, fed it to Nana's mouth.

"Whew." Nana chewed and swallowed it in one gulp, with a look of unfinished business.

No way, I fed her another spoonful.

The juicy mushrooms, paired with just the right amount of soup, are indeed a rare delicacy in these hundreds of meters underground.

A big bowl of mushroom soup was quickly divided between you and me.

I'm full, so satisfied~

At this time, Sora and Nana's hearts are connected, and the two foodies are sitting on the ground, and neither of them wants to move for a while.

……

After 20 minutes, Shi Shiran got up from the ground, patted the dust on his pants, and first washed the lunch box that had cooled down and put it in his backpack. Then pack up the leftover mushrooms and finally fill the water bladder.

He was ready to go again.

Nana was still walking in front, and after eating, she could see that she was energetic and very energetic.

Sora followed closely behind, and marked the fork when it encountered, and by the way, observed whether there were any traces left by predecessors on it.

After continuing to explore for an hour, he really found one, and when he first saw the circle mark carved into the rock wall, he thought he was dazzled, and quickly told Nana in front of him to stop. If you look closely, it is indeed obvious man-made traces, but it may be because of the long time, you can't find it if you don't look closely, you have to have a good pair of eyes, otherwise you will miss it.

Finding the first artificial marker boosted Sora's confidence, which proved his idea right. If you can find more markers later, you will be rescued!

In the subsequent explorations, Sora significantly quickened the pace. He had been alone in the darkness for almost a day, and the dim environment, like an endless tunnel, and the wild spirits that popped up from time to time, all of this tormented his nerves all the time. If it weren't for Nana's company, he suspected he would have collapsed.

Now he desperates for light!
