Xia and Luo Ye walked in the passage, followed by several students from the Department of Science and Technology.

"This place must be very deep underground, and there is still a hidden space underneath?"

Xia asked Luo Ye with some doubts.

The school garden is transferred through guò space, and the whole is moved.,In her cognition,It should only be a shallow layer above.。

"It seems that classmate Xia, you have not studied the theory of the Great Transfer thoroughly."

Luo Ye walked in the same posture as her character, cautious and rigorous, looking straight ahead and replied:

"The spatial transfer is different from most dimensional attack magic, and what is truncated is not a plane, but a sphere."

As she spoke, she gestured in the air:

"Because the sky above the school park is air,So there's no need to calculate it when transfering.,The rest is just a simple draw out the diameter.,Finally, form a complete sphere; At this point, the width of the ground is cut, from the tallest building on the surface to the depth of the ground, so you should be able to understand why we can still use the groundwater after being here for so long, right? ”

Hearing her words,Xia silently measured the width of the school park in his heart,There was a vibration in my heart:

Because this school park is built too big.,I'm afraid the width is more than tens of kilometers.。

In this case, the thickness of the rock layer that moves along with it is ...... Isn't it the equivalent of a small island with a size?

-- Many islands don't have this width.

"Of course, a lot of the groundwater sources come from other places, and they will soon be gradually depleted, and we basically rely on the storage of underground reservoirs to live, and then the science and technology department sends some simple pipes down from all over the place, deep into the closed water storage rock formations, so the water supply of the library can be guaranteed in a short time."

She pushed her glasses: "Of course, it's only for a short time...... Sooner or later, the stored water will run out, and most of the water sources on this island will be polluted, and even if there are some clean spots, it will be difficult to obtain and difficult to transport, because there are too many monsters and the water is heavy. ”

"Then there are so many of us, won't there be no water available soon?"

Natsu's words were full of concern.

As with food, finding water in the wild is a big problem; And many times, securing water is even more important than getting food.

"Yes, I was worried about the water source for a long time, but I didn't expect to come here, and the problem was temporarily solved...... Because we found a water recycling system in a secret base, and it was built with very advanced legacy technology, which is very efficient. ”

Luo Ye and Xia turned a corner, and the passage in front of them began to slope downward, Luo Ye looked at the wet ground on the side of the road and said:

"But from now on, people can't be as careless as before, and domestic water, including bathing, needs to be carefully planned. The little guy in the back proposed the concept of a collective bathroom, and everyone may go into the big bathroom to take a bath together in the future, which will save resources more; Of course, there will be separate male and female trainees. ”

She gestured back.

Xia saw a short female student among them, the alchemist girl who spoke like a machine gun, and her name seemed to be Sharo.

"Hey~"

Sara's personality seems to have always been optimistic, and after seeing Natsu looking at her, she happily said hello and jumped in place.

I don't know how the disciplines in Wang Li's school are classified, Xia has always thought that alchemy is exclusive to the Department of Magic, but this student of the Department of Science and Technology is obviously also an expert in alchemy.

"Let's take a shower...... Forget it. ”

Xia thought of the things he had done before, and sighed secretly.

"Master, I've found Agnes' location."

At this time, Stephanie flew back, and it looked like she had searched a considerable distance this time, and it took quite a while.

"She's okay, right? Where are you now? ”

Xia asked anxiously.

"She's locked up, but she doesn't look like she's hurt."

Stephanie replied quickly.

"Locked up? Who can lock her up, and without hurting her. ”

Xia was really surprised this time, except for Delia, she really couldn't imagine that anyone would have such a strong strength to be able to directly confine up Agnes, who had changed careers for three years.

"What is she locked up in? Iron cage? Magic Seal? No, these things should be hard to keep her...... Is it put on a forbidden chain? ”

She tried to calm herself down, and kept thinking about what might have happened in her mind, and asked Lori in black.

"This ......"

The black-clothed Lori looked a little hesitant.

"What's wrong? Say it. ”

Xia asked anxiously.

"What locked her inside was a dark green ball, and the magic composition on it was very strange, and this kind of high-strength elemental collection would not normally appear on the mainland, and I think the only one who could do this was ...... Artifact. ”

"Artifact?"

Natsu's footsteps stopped.

A ridiculous feeling arose in her heart:

"You mean, there's another Divine Fragment here?"

"Of course not! Master. ”

Stephanie looked dissatisfied:

"How could the fragments of God come together? Don't forget that I was sealed here, and there will be a connection between the fragments, and if there is, I can't be unaware of it; When I say artifacts, I'm just referring to those defective goods. ”

"Classmate Xia, why don't you leave?"

Luo Ye noticed that Xia stopped, turned her head and asked strangely.

"I suddenly thought of something very important, go first!" Natsu took the shotgun on his back in his hand:

"Stephanie, lead the way!"

"Over here, master."

Stephanie led her forward, leaving a stunned crowd behind.

The passages around him were getting darker and darker, and there was no light at all in front of them, and Natsu's eyes could see in the dark, and they were flying through under the guidance of Stephanie.

"Click......" Her footsteps occasionally stepped on a puddle of unidentified liquid, echoing through the dead silence of the hallway.

"What's on the ground over there?"

Coming to an entrance, Natsu noticed a humanoid object on the ground, slowed down, and asked vigilantly.

Stephanie flew over to look at it, and came back and said:

"Like the dried corpse in that room, it is also a corpse that has been dead for a long time, the environment here is a little damp, it has been very badly decayed, and all that is left is crispy bones and a few flesh remains."

"Click!"

Natsu opened the shotgun and took out the bullets that were originally filled inside, and replaced them with light bullets.

"Keep walking."

For some reason, she felt a strong sense of oppression in the area in front of her, much stronger than in the library in the middle of the night.

Due to the urgency of time, she did not bring the black long knife this time, and could only use two magic guns to fight.

All the way to the depths of the earth, Stephanie spotted an acquaintance in the distance, and the route happened to collide with them face to face.

"Mother Elisa?"

Natsu didn't expect to see this nun of the Order here, and it seemed that he hadn't seen her in days.

Mother Alyssa, who was hurrying forward, was startled when she saw a person suddenly appear in the darkness ahead.

"Your Highness, Your Highness!"

The nun showed a look of fear in her eyes when she saw Queen Xia, and bowed her head at her, as if she already knew Natsu's identity.

"What are you doing here?"

Looking at her hurried appearance, Xia couldn't help but be suspicious.

Mother Alyssa is an ordinary clergyman, and her combat power is very weak, so it is a bit strange to venture to such a deep ground by herself.

“…… I'm lost. ”

Mother Alyssa's eyes twinkled, and she lowered her head and didn't dare to look at her.

Do you take me for a fool?

Natsu almost sprayed this sentence in her face.

But thinking of Agnes's situation at this time, he was not in the mood to continue to deal with this guy, and ran forward with his shotgun in hand.

Behind her, the nun looked at her figure with a hint of resentment in her eyes.

"Master, there are a lot of people ahead!"

Stephanie reports.

Natsu scurried out of the corrupt passage and saw a group of people gathered around a door to study.

She hid in the shadows, and the people over there suddenly cheered in unison, as if some problem had finally been solved, and many of them had a relieved look on their faces.

I saw a blonde girl with a double ponytail walk up to the door surrounded by everyone, and with a divine light in her hand, she pushed towards the door.

"Is there any other way?"

She didn't want to meet anyone else right now, especially when Wendy was there.

Rescuing Agnes was the most important thing on her mind right now.

"It's going to go a little farther away, master, come with me."

Stephanie turned into a path.

"There's a lot of water on this road."

Xia looked at the waist-deep stenched water in front of him, and stood on the stairs and quickly activated the elemental resonance.

Two light purple wings glowed in the darkness and emerged from her waist, and this time she didn't let the wings appear on the sides of her thighs, instead opting for a more stable middle.

"Uhhh

She tried to hover in the air and rushed forward.

There was no sign of man-made structures in the area, but instead turned into a jagged rock wall, the protruding rock was covered with slippery dark green moss, and the water under the ground gradually deepened, and later it was able to overflow overhead, leaving only a narrow area for her to fly.

"Master, above!"

Xia Kongzhì held her wings, trying not to let her body contact the water, and after flying for a while, a huge cave suddenly appeared, and she looked up in the direction pointed by Stephanie and found that there was a dark green sphere embedded in the rock wall at the very top of the cave, and Agnes was sitting in it with her head down, her face buried between her legs, and she couldn't see her expression clearly.

"Xiao Ai, don't be afraid, I'm here to save you!"

Natsu launched a transmission at her from afar, and the wings on her waist fluttered, drawing a glowing trajectory in the dark air, rushing towards the green ball above.

Agnes's body trembled, and she lifted her face from between her legs, and immediately knelt in it when she saw the queen of summer, and kept slapping the ball with her hand, as if shouting something there.

"Master, she seems to be saying, let you go quickly."

Stephanie looked at the shape of her mouth and said to Natsu.

"How could I go! Keep me on guard, that enemy may still be nearby. ”

Xia rushed to the bottom of the ball, his face suddenly turned red, and he looked away.

Agnes went out with nothing underneath, a subtle angle that made her see the old Band-Aid again.

Although she looked away, her movements did not stop, reaching out and touching the surface of the sphere, the dark green ball shook violently, like a bubble "popped" and burst, Agnes's body fell out of it, Xia reached out below and took her firmly in his arms.

"Sister Xia!"

Agnes threw herself on her shoulder, lying between her silver hair and breathing greedily, and suddenly thought of something, and straightened up suddenly:

"Sister, let's go! The enemy who trapped me here is terrible, and we are definitely no match for him! Get out of here! ”

As she spoke, pitch-black wings also appeared behind her, taking Natsu's hand and rushing downward.

"Stephanie, have you detected a powerful enemy nearby?"

Seeing Egnes's frightened eyes, Natsu's heart also hung high.

"Not yet, master."

Stephanie shook her head and said:

"But I'm not sure, because some powerful beings can hide their aura, and as long as the other party is not hostile to the master, I can't detect the other party's location......"

At this moment, a loud roar suddenly echoed throughout the cave.

Both of them felt a strong shock in the air, Agnes covered her ears in pain, Natsu's eyes glowed with blue light, Agnes felt that the piercing roar disappeared in an instant, and looked around in surprise, not knowing what had just happened. R1152
