After the previous battle, the lower Ozarzi around the World Axis was either cleared or fled elsewhere.

This made it a lot easier for Sivi and Siwei to explore downward.

"This is where we fought." Looking at the remaining traces of battle on the world axis, Sivi sighed a little: "I didn't expect that I could really fight with the overwhelming Ozarchi for so long when my strength was suppressed to that extent, and I managed to survive......"

"It's the first time I've encountered this situation, and even if I fought against Robert Veron, it wasn't so scary."

Sivi also sighed.

and Robert slashed against ...... Girl, you're such a man......

Sivi's face was black.

"Ready to continue diving," Xiwei didn't care about the subtle expression beside her, and planned to continue to set off towards the center of the earth: "I have only been to that depth once, and it is still near the cliff of the Western Continent, and it is estimated that the depth of the strata on both sides is also different, and the Eastern Plains here have to dive at least nearly a hundred kilometers." ”

"It's all to the mantle, right?" Sivi couldn't help but sigh when he heard this.

Although this thing has also been in places like dungeons, except for the bottomless pit that engulfed Shakespeare's Minick Academy, the deepest place he has been to is no more than 2,000 meters......

In fact, in that magical world, the deepest known natural cave in the Eastern Plains was only about 1,700 meters, but the deepest recorded pit excavated by hand was more than 2,000 meters - after all, in a world with supernatural powers such as earth element magic, digging a hole or something was relatively simple.

"There doesn't seem to be such a setting as a mantle in this world, if you continue to go down, although the temperature and air pressure will rise, but they are still within the range that the human body can bear, at least the lives of the people and soldiers who went down with me at that time were not in danger." Sivi paused, then continued, "Of course, I haven't been to that kind of place when I'm on Earth, so whether it's different or not, I honestly don't know...... It is also possible that people in this world are more adaptable to this environment. ”

After saying that, she found that Xiwei didn't seem to be listening to her, but staring at the outer wall of the world axis in a daze. I can't help but be a little curious.

"What are you looking at?"

She reached out and poked Sivi, causing her to nearly fall off the Gundam (yes, they came down from Sivi's Gundam).

"Sure enough, someone else has been here," Xiwei complained casually at first, but was completely ignored by Xiwei, understanding that the girl's personality was very hearty, and in a sense, he was a little close to a tomboy, and he could only laugh helplessly, and said what he had just discovered: "There is an unknown energy left on the wall, not magic that I know." It's also different from the prayer you used before. ”

"The power system of my world is relatively messy, unlike your side, almost all of which are magical, but the attributes are different." Xiwei lifted the tips of her hair and looked at the place where Xiwei pointed, her long black hair swaying with her movements: "In addition to the power of prayer, this world also has powers such as natural aura, soul ripples, and divine grace glow, almost all of which are not homologous, for example. Some people will refine the blood of monsters into their own bodies to refine it into a special bloodline called 'source blood'. When these guys activate Source Blood, they will have a monster-like power, which is called Source Blood Power. ”

Because she didn't have the keen perception of energy like Sivi, even if she looked at the place that Sivi pointed out, the girl didn't see anything useful.

In the end, Xiwei could only record the fluctuation of that energy a little, and continued to dive with Xiwei.

"Speaking of which, when you hunted down that plant-type Ozarzi core before. Didn't you dive quite a long way too? I had taken the moment to look down to find you, but I couldn't see anything but a few flashes of light. ”

Sivi found a flat spot on Gundam's body, sat on the ground without any image, and then found a topic of conversation in boredom.

"That thing escaped very quickly. It took me a lot of effort to chase it. Xiwei smiled bitterly and said, "After all, I left this thing at that time (she patted the Gundam), although my own flying ability can be said to be impressive in front of me, but the movement is not very flexible, and it is very troublesome to chase." Fortunately, it was weak, and the weakness was obvious, and I killed it with a single sword. After that, in order to save you, I didn't pay attention to the surrounding situation, so I rushed straight up......"

There was an awkward silence between the two.

After a while, Xiwei scratched his face a little embarrassed: "Anyway, thank you for saving me at that time." ”

"This world is my territory anyway, and letting you, as a guest, die in another territory, it's not a good thing for my reputation~"

The girl raised her face proudly, and without waiting for Sivi to say anything, she hummed an unknown song.

The melodious singing echoed in the dark corridor, although it was an unaccompanied cappella, but you could still hear the beautiful melody of the original song, coupled with the girl's clear and sweet voice, the feeling was unexpectedly good.

At the same time, Xiwei also discovered the difference between the two again-before the crossing, Xiwei was the type who sang super badly, belonged to a KTV with friends, and when he came out, except for himself, everyone else had a psychological shadow at that level, and people gave him the nickname Shadow Maker.

After closing his eyes and enjoying himself for a while, Xiwei suddenly opened his eyes and frowned: "Xiwei, you stop first." ”

"What's wrong?"

The girl stopped singing and looked at Sivi curiously.

The latter did not answer, but closed his eyes again, but this time he was expanding his senses.

After a while, he opened his eyes again: "I thought that the strange energy I just discovered was left behind by the uninvited guest to send Ozarzi here. But now it seems that there is a slight mistake. ”

"Isn't Ozarzi the owner of that energy?" Sivi touched her nose thoughtfully, then asked.

"No, that's not for sure." Xiwei shook his head, and then stopped selling Guanzi: "But if he didn't get it, I think it's better to ask him directly." ”

"Do you mean that the owner of that energy did not leave this sinkhole, but hid underneath?"

"That's it." He nodded in confirmation of the girl's guess.

So under the control of Xiwei, the large alchemy figure (that is, Gundam) they were riding accelerated and flew downward, and the feeling of weightlessness like bungee jumping filled the whole body of colleagues, and a figure appeared in the field of vision of the two of them, blessed with night vision...... (To be continued.) )
