"It's still recovering."

On the third day, the team was ready to go, and Xia went to see the situation of the Black Calamity.

The black horse lay quietly on the ground, and the knight sat motionless on the horse's back in the same posture as he had been pierced by the sword that day.

The spear in its hand was stuck in the ground, and the cursed black mist around it was much thinner, and it seemed that all of it was back in the silver-white armor, healing the wounds in its body.

The elemental creatures had tried to attack the statue-like knight, but none of the monsters, including the leaders, could break through its armor, and it was gone.

"It would be nice when I had this armor too."

Xia thought enviously.

She turned and made a safe gesture to the crowd, escorted by a crowd of fire demons, and walked deeper into the plains.

Elemental creatures do not have a good means of communication, and most rely on roaring to convey information, and powerful individuals of the same race can occasionally use spiritual transmission, but the range is not large; This plain is very vast, so it is necessary to allow the fire demon to communicate with the other party so that he will not be attacked.

"If we were to walk on foot, it would take half a month to cross here."

Listening to the prediction of the black-clothed little Lori, Xia was a little frightened by the huge underground world, their speed can be regarded as quite fast, and it will take 2 weeks to cross the plain.

"It's a pity that Stephanie can't fit a magic car, it's much easier to have an off-road vehicle in this kind of terrain."

"Speaking of which, it seems that the people of Abner and Merlin are going to work on some kind of one-man flying device, and I don't know if they have succeeded now."

She suddenly remembered the people she hadn't seen since she left Necronomicon Island.

"When the matter here is over, maybe I can go to all parts of the mainland to visit the former students, I don't know how they are doing now."

In the curious eyes of all kinds of elemental creatures, half a month passed quickly.

"Master, this is the last place to bury food."

According to the master's instructions, the black-clothed little Lori hid food and water every once in a while during the reconnaissance in case of emergency.

"Hurry up and recycle it, unlike in your space, these things will break if you put them outside."

Xia walked over to help the black-clothed little Lori get something, but when they dug up the ground, both of them were dumbfounded:

- Food and water are gone!

"Elemental creatures shouldn't be able to touch these things."

Xia frowned and thought for a while, and said slowly:

"Here...... I'm afraid there are others. ”

Mondoli is obviously the most suspicious, he can fly, it is not difficult to sneak across the plains from a high place, although the angelic state does not need to eat, but it consumes life force, if there is food and drink, he should be happy to release the possession state.

"The food here can last an adult for seven days, and we have to be extra careful during those seven days."

She told the others about what she had just discovered, and then Sadonan made a different opinion:

"In addition to Mondoli, there are actually some unaccounted for people in that team; After reaching a certain level of strength, they can survive even in very harsh environments, and those people may not die, but persist in getting here. ”

"Cole can rule it out, he is a pure swordsman, neither fighting nor flying spells."

Delia recalls the voices and signs of the atheists:

"There is a man who can fly, but his strength is not very strong, and if it were him, he would not pose a threat to us."

"It's also possible that the people of Truis are still alive."

The Lich also gave his opinion:

"Anyway, we try to pay attention to ...... After listening to the little guy's introduction, the deep pit ahead gives me the impression that it is a very dangerous place, so don't fall into the enemy's trap like you did last time. ”

It says what is happening in the ogre tribe.

After coming to the deep pit that the fire demon and the black-clothed little Lori said, everyone felt a chill in their hearts.

It was a terrifying crater that looked like a huge basin, starting at the edge and gradually descending, with a dark abyss in the center.

"I can't see the bottom."

The werewolf princess glanced down, felt a little dizzy, and immediately retreated.

"Stephanie, this irregular opening, and the downward depression...... Isn't it similar to the crater at the ancient elven ruins? ”

Xia saw a clue and asked the little Lori in black.

"Seems like yes, master."

The little Lori in black flew over and looked around the pit:

"It seems to be the same size."

"This shouldn't be accidental."

Natsu walked over to the swarthy hole and kicked a pebble into it.

After a long time, no sound came.

“…… Are we really going down? ”

The half-elf girl shrank behind Delia, neither of them very good at facing this deep hole.

"I don't think it should matter."

Xia thought seriously for a long time:

"The underworld, though deep, is not endless; I once saw a theory about the structure of the world, that the world we live in is a circular sphere, its surface to the center is about 6,300 kilometers, and we are now in the very deep underground position, and this hole cannot penetrate the center of the earth no matter how deep it is. ”

This so-called 6,300 kilometers is the radius of the earth, although the world is different, and there is nothing wrong with using it as a reference.

"How long can the supply last?"

She asked in her head.

"It's been less than 4 months, master."

"Stephanie, fly down and take a look."

Xia made a decision:

"1,000 kilometers is not a very long distance for you, and I guess the depth of this hole should not exceed 3,000 kilometers, so you can fly according to the 3,000 kilometers distance, and when you reach the bottom, take a closer look at the environment there, and then come back and tell me."

After the black-clothed little Lori took the order, everyone stayed at the edge of the pit.

None of them wanted to get close to the terrible hole, so they chose to camp farther away, and everyone was recuperating and waiting for the arduous journey that was coming.

On the fourth day, the black-clothed Lori returned from the cave with a surprising news.

"There's no lava down there, and it's not some dark subterranean space, it's seawater?"

Xia said in surprise.

"Yes hosts. It was surrounded by a large orb that looked like a kind of barrier against the sea; I flew out of the ball and tasted it, salty...... With the smell of the ocean and strong water pressure, it should be very deep on the seabed. ”

The little Lori in black replied with an oath.

"It's not scientific at all."

Xia bowed his head and groaned:

"The maximum depth of the Mariana Trench on the earth is only about 11,000 kilometers, and 1,000 kilometers of Stephanie can fly back and forth in one day, but it is difficult to reach the depth of more than 3,000 kilometers in the world's oceans? That's 3 million meters!

"And, why the bottom of the sea? And not the center of the earth? ”

She felt a little confused in her mind:

"It's supposed to be the deepest part of the underground world down here, how can there be a sea?" R1152
