It's an indescribable smell.

It's not a foul smell, it's not a good smell to be addictive, it's like moss that hasn't seen sunlight for a long time, and the acid secreted by it dissolves the ancient smell of the rocks.

The smell fills the dimly lit underground space in front of you, and occasionally you can feel a wind blowing through them, sweeping them away, and slowly recovering after a while.

"These rock snakes are so unreliable, it is clear that there are no plants, what is on this stone."

Natsu looked at the vine-like creature on top of a rock, dissatisfied.

"This is the Erondo silver fern, a species that can grow in the underworld, and it is widely distributed."

Natyavida knew much more about plants than she did, crouching on the edge of the rock, looking at the shiny stem, and touching it lightly with her hand.

Silvery veins suddenly appeared on the surface of the rock, just like the linear lights that Xia had seen on Earth before, illuminating the surrounding environment.

"Rock snakes are carnivorous monsters themselves, and they live in deserts and rocky fields with few plants, so it's too much for you to ask them to judge accurately."

The half-elf girl looked at the scene in front of her by the light of the silver fern, and her eyes were fresh.

Dwarves like to burrow into the ground, but elves don't like dark and damp places, and although she has been in caves, she has never seen the real underground world.

"Legends seldom match reality."

Natsu thought as he looked at his surroundings.

Where are the traces of excavation here? It is simply a very ordinary underground karst cave, and those stalagmites cannot be artificially formed.

Even if the Black Calamity is close to the existence of the gods, if someone says that it can produce a lot of stalactites with a single shot, a silver-haired girl will only laugh out her big teeth.

"But that's fine, otherwise if you encounter that thing underground, you won't have a place to run; The other party will obviously use the teleportation array as well. It's not the kind of inferior undead who don't have intelligence. ”

Secretly glad she had chosen the right route, she glanced back at the teleportation array, pulling Natya Vida to a place where the entrance was out of sight.

"Look, there's moss in here."

She took the half-elf girl's arm and pointed to the bryophytes on the ground in surprise.

"Of course there is, and this stacked tower moss can often be seen underground. If the silver-threaded fern is the guiding light of the underworld, then the tower moss is a signal of danger, and they can sense poison gases and disasters. ”

Natya Vida didn't know that she had brought herself over on purpose so that the little Lori in black could secretly use the teleportation array; I thought she was really interested in these plants, so she patiently acted as a commentator.

"I know that bryophytes have only one layer of cells in their leaves, and many toxic gases can invade the leaf cells from both dorsal and ventral sides, making bryophytes unable to survive, taking advantage of its characteristics. It can be used to detect air pollution. ”

In order to show that he is knowledgeable in front of his lover, Xia accidentally uses a term on earth.

"Cells? Air pollution? ”

Although she had some knowledge of legacy technology, Natya Vida had no exposure to these things, and tilted her head and asked.

“…… It's a title I've seen in an ancient book, and I don't know what it means, but it's supposed to be a very esoteric subject just like when the magic factor was first discovered. ”

Natsu took Natya Vida around the entrance, and then summoned some monster bats that couldn't be eaten. Let them spread out in several directions and explore the cavern with sound waves.

Natya Vida was not idle either. She sent a carpet search of the stealthy subterranean creatures, including the fat gophers she had seen before, and these creatures with dark vision, though flightless, were perfect for reconnaissance in such environments.

"There is no sun or beach, but it's still a great place for couples to be alone, especially if you're both adventurers. An underground adventure for two! How sentimental this kind of thing is. ”

Now that there is no crisis in front of him, Xia begins to have bad ideas.

"Nana, after such a long drive, aren't your legs sore? Let me give you a massage. ”

She said to Natyavida, who was sitting there with a notebook and writing down something.

Then he quietly got up from where he was sitting and walked behind her.

"We didn't go very far, did we? Flying most of the time. How can you have sore legs? ”

Natyavida didn't realize her evil intentions and replied by looking at the notebook on her lap.

"Yes, yes."

Natsu, who was about to start, retracted his hand again.

"But, Xia ...... I'm glad you could think of bringing me to such a secluded place...... But don't you want to go and save those in need? ”

Natya Vida stopped her pen and turned to her and asked:

"I remember when you were on Necronomicon Island, you often took the initiative to lead people to solve crises...... Many problems that others seem to be unimaginable have been solved by you one by one, and at that time I felt that you were really amazing, and there was nothing that could hurt you. ”

- Because then I knew where the plot was going, dear Nana.

Xia looked at her gaze with a hint of hope, and sighed in his heart: "Most of the game plot takes place in Wang Li School Park, and it's over in just two years, I don't know what will happen next; For example, this world-destroying star, I had never heard of it before. ”

What's more, at that time, she had Wendy and Delia, two super powerhouses, and later a demon black cat; The most dangerous area on the island, the people of Morgendona never really went in at all, and only wandered around the edge before returning.

"I can't even appear in the kingdom openly now, how can I save others."

She said helplessly, and then sat down beside Natia Vida.

"Why? The royal family and the Order want to officially crown your heroic princess, and the students who were saved by you also organized a large search party to go to that island to find your whereabouts, but then it was disbanded for unknown reasons, and many people cried a lot for this. ”

Natya Vida tells two events that Natsu had no idea about.

"Maybe someone who knows the truth has persuaded them, President Wendy, El, and Agnes. Lorraine, Ebner...... I made these people clear to them before leaving, but I can't tell them the real reason for not returning to the royal capital. ”

Xia looked at the half-elf girl and suddenly hugged her in his arms.

"Summer, you ......"

Natyavida writhed twice in some resistance, but finally let her hold herself.

"Didn't you say you were going to give me some time? You've always been like that. ”

She leaned her head on Natsu's body and whispered.

"Just thinking about whether you really like me?"

Natsu kisses her long black and cyan hair:

"You seem to think differently than other girls, but in general, you should first worry about why you don't like men, or do you like girls in the first place?"

"Looks like you'll need to make up for the elves, little fool."

Natya Vida patted her on the leg, then stroked it again:

"The elves are most interested in nurturing life from nature, not by marrying to continue their offspring like humans; It doesn't matter if it's a man or a woman, as long as it's pure and immaculate, they'll love it. Not to mention that girls fall in love with girls, even between men. ”

Then she felt Xia shiver.

"What's wrong, Natsu?"

She looked up in confusion.

"I didn't ...... It's nothing, I just think the elf's mind is really open-minded, aha, ahaha......"

Xia Gan said with a smile.

- There are fagots in the elves, too?

She pondered in her heart:

It is said that nature breeds life...... How did the elves of this world come about? It doesn't grow out of a tree.

She remembered certain myths and fantasy stories, in which elves were born in various ways, and she didn't know which kind of elves from this other world would be.

"Hmm!"

Then she felt her thigh be twisted hard.

"Don't think about those elves!"

Natya Vida said with some anger.

After screwing. She pinched her black stockings a little with her fingertips, as if curious about the material of the thing. Pull up and play there.

Just like last time, how did she know what I was thinking?

Xia held back the pain in his leg and wondered in his heart.

The twist was so heavy that her thighs trembled slightly, and it took a while to calm down.

"Nana, I actually have something to tell you."

She grabbed Natia Vida's hand playing with stockings. Leaning in her ear and saying:

"Actually...... The end of this underground passage is where magical leaves can be obtained. ”

Natyavida's body stiffened.

"You're not lying to me?"

She kept her head down, unable to see the expression on her face.

"How could I lie to you."

Natsu pulled her body up, and the two hugged each other face to face, a position that made the half-elf girl a little shy. Turned his head to the side.

"If you lie to me, I'll ignore you in the future."

She looked at the rock next to her and said:

"It's so important to me."

"It's important to me, Nana."

Natsu kissed her on the cheek:

"But because it's important, we need to think long-term...... I'm only here to avoid disaster, not to set foot with you on the path full of death traps in front of you, which is too dangerous for us right now. ”

"Where did you hear about this place?" Natia Vida listened to what she said, and asked worriedly.

"It was a village that had been cursed for a thousand years......"

Natsu told the story of what happened to her beloved girl, and when she heard the appearance of the terrible knight, Natyavida exclaimed:

"Black Calamity! You're running into that kind of thing. ”

She hugged Xia tightly, and was afraid for a while:

"You're so reckless, how dare you track it down!"

"I should have asked you about the ...... of the uncle."

She glanced over to this side with eyes that tickled Natsu's heart, and then beckoned into the distance.

"Squeak!"

A chubby gopher came running up and pointed behind him with his front paws.

"These little ones seem to have discovered something, let's go over there and have a look."

She left Natsu's embrace.

"You dead rat, I'll stew you in a while!"

The silver-haired girl stared at the fat gopher viciously, causing it to run and hide behind a rock.

"Don't come here yet!"

Natyavida made a stop gesture.

"Sizzle......

A flash of magical brilliance flashed, and a snake appeared from her feet.

The snake was snow-white and swam forward with a letter in it.

Natsu jumped into the air, reached out and grabbed a stalactite, looked from a distance, and found a bright light slowly floating from the darkness.

The light is yellow and white, and it looks like a firefly, but it is much brighter than a firefly.

"Snails?"

She found that the light was coming from the top of a tall snail's head, its two eyes to be exact.

At this time, the white snake hiding in the shadows suddenly rushed out and bit the snail's head.

The light dimmed instantly, and Natyavida beckoned the snake back, strode over to the snail, pulled it up from the ground, and focused on its eyes and mouth, before bursting out of her hand with a cloud of ice mist, condensing it into ice.

"This is the Firefly Snail, it is known as the eye of the ancient giant, and it is the patrol monster of the giant's territory!"

She threw the snail that had turned into ice to the ground and turned to look at Natsu:

"Summer ...... What kind of place have we come to? (To be continued......)
