of the inside.

After flipping over, the four of Lu Xia suddenly fell from mid-air, and after descending a distance of dozens of meters, they landed here.

Fujimaru Rika was held by Ryuxia, and Meltellith and Nero also adjusted their landing positions, and soon landed safely, and the servants fell from this height without being damaged.

"Thank you, Ryusha-chan."

After getting out of Ryuxia's embrace, Rika Fujimaru breathed a sigh of relief, thanked Ryuxia, and looked at the surroundings.

She has already experienced a lot of compulsion in this crisis situation in the past, and she is not shy about it.

The entire interior environment is almost carved out of the same mold as the surface side, whether it is the wall or the floor, it is still the same transparent and hard material, and it is also a labyrinth-like structure.

It's just that the outside is no longer an endless ocean depth, but an East-West building that came out of nowhere, and it looks quite out of harmony with the scenes of classical lofts in the East and modern amusement parks in the West.

I don't know what kind of principle makes up such a landscape, but it has nothing to do with the people of Liuxia, and they didn't come here for sightseeing.

"This is the inside...... If this is the back of the flank, the road to the back should be this way. ”

Rika Fujimaru pondered as she identified the path and direction.

According to Melter Lilith, the surface and the inside side correspond to each other in terms of position, road, direction, etc., all of which are mirror symmetrical, in other words, they can deduce the general direction of the inner road when they already know the surface road.

"Lilith, how much area is there?"

Fujimaru Rika didn't act immediately, but asked Meltrilith questions.

"The inside area?"

Meltlilis groaned when she heard this, and the momentary look of unwillingness on her face had long since been put away, and she had become as calm as ever.

"I don't know much about the inside, but as far as I know, there should be at least three areas: the back, the buttocks, and the calves......

The surface side and the inside side are corresponding in position, and they should be complementary in area, after all, they are standing inside this female body, and the surface and the inside are at most two different sides, and in fact, how many organs and limbs should be the same, no matter which side you look at, after all, it is essentially just a person.

It is impossible to say that there are two arms on the side of the watch and two arms on the inside, which adds up to four arms, which does not match the shape of this one.

However, Meltrilith actually left half of what she said just now, in fact, she basically knew how much area there was inside, but she didn't tell Fujimaru Rika directly.

The subjective statement of "not much" is not a lie.

On the surface, there are only three areas on the back, buttocks, and calves, but in fact, there are several areas that are hidden, and they will not be revealed until the first three areas have been explored.

The reason for this troublesome mechanic may only be BB's bad taste.

"Is that so...... In that case, no matter what, saving people is the first priority. ”

Fujimaru Rika thought about it and made a decision, "Go to the back area first, go from the back to the chest on the side of the table, rescue the employees trapped in the control room first, and then come and explore the location of the celestial room." ”

It really looks like something that would be said by her character.

The crowd didn't have an opinion, either agreeing or nodding indifferently.

After making a decision, several people followed the identified path and walked upward, intending to enter the back area from the back of the neck.

Just as the road to the chest only has a fork in the neck, the road to the back is only a fork in the neck.

After going up the flanks, several people quickly came to the back of the neck.

However, unlike the imaginary four-way crossing, there are actually only three forks to the left arm, the right arm, and the back, and the last fork to the head is not a passage, but a main entrance, in other words, the entrance and exit of the labyrinth.

"Didn't you say that the main entrance to the base is on the top of the head?"

At the back of her neck, Fujimaru Rika looked at the entrance and exit in front of her, and couldn't help but show a puzzled look, "Why is this another main gate?" ”

Factories and bases that carry out fully enclosed management rarely have more than one main gate, and in the case of Chaldea, there is basically only one main gate, which is the entrance opened by Kotaro the Wind Demon on the day Ryuxia first arrived.

Setting up multiple main entrances in this kind of place will only increase the turnover of employees, which is inconvenient to manage and has no advantages.

"Huh? Didn't I tell you? ”

When Meltlillis heard this, she said noncommittally: "The main entrance on the side of the table is used by ordinary employees to enter and exit, that is, those employees who are related to the exploitation of oil fields. ”

"And the main gate here is the privileged staff, such as the Chaldean messengers, or the special main gate used by the magicians, that is, the main gate that has been magically treated."

Meltrilith chuckled, "This is a dual structure, ostensibly an ocean base for extracting oil fields, but in essence it is a workshop for magicians, didn't I tell you?" ”

"No, not at all!"

Fujimaru Rika waved her hand vigorously, but then she suddenly got up, "But that's right, after all, it's one of the subordinate organizations of the Chaldeans, and if it is not related to magic, it is unlikely...... But in that case, maybe the Celestial Laboratory has conducted experiments related to magic in the past? ”

They had also asked Marbur about the Celestial Chamber, but Mabur replied that he had no idea of the existence of the Celestial Chamber.

Considering that Marbur was just an ordinary employee, the gymnasium was probably not something that ordinary employees could know, and it was probably a place that only magicians were qualified to step into.

In fact, her reverse reasoning is indeed very correct, the celestial chamber is conducting magic experiments, but because it is too involved, neither Ryusha nor Mertellith has kept silent about this matter until now.

And, it is worth mentioning that the experiment was not just carried out in the past, but is even ongoing now.

"Okay, it's none of our business at this main gate, let's go through the fork in the road."

Apparently not wanting to continue the discussion on this issue, Mertrillis quickly changed the subject, beckoned Fujimaru Rika, and walked towards the fork in the road.

That's where the passage to the back area is located.
