After the previous battle, the lower Ozachi around the world axis was either cleaned up or fled to other places.

This made it much easier for Xiwei and Xiwei to explore downwards.

"This is where I fought before." Looking at the remaining battle traces on the world axis, Siwei sighed: "I didn't expect that I could really fight the overwhelming Ozaki for so long when my power was suppressed to such a level, and survived successfully..."

"This is the first time I have encountered this situation. Even when I was fighting with Robert Velen, it wasn't that scary."

Xiwei also sighed.

Killing with Robert... Girl, you are such a man...

Xiwei looked dark.

"Prepare to continue diving," Xiwei ignored the subtle expression beside her and planned to set out toward the center of the earth: "I have only been to that depth once, and it is near the Xilu Cliff. It is estimated that the depth of the strata on both sides is different. At least one hundred kilometers will have to dive in the eastern plain."

"Then it's all to the mantle?" Siwei couldn't help but stutter when she heard this.

Although this guy has also fought in dungeons, except for swallowing the bottomless pit of Shakespeare Minnik Academy, the deepest place he has been to is no more than 2,000 meters...

In fact, in that magical world, the deepest natural cave known in the eastern plain is only about 1,700 meters, but the deepest mines recorded by artificially excavated have exceeded 2,000 meters. After all, in a world with supernatural powers such as earth element magic, digging is relatively simple.

"This world does not seem to have the setting of mantle. If you continue to go down, although the temperature and air pressure will rise, they are still within the range that the human body can bear. At least at that time, the civilians and soldiers who went down with me were not in danger of life," Siwei paused and continued: "Of course, I have never been to that kind of place when I was on Earth, so it is different. To be honest, I don't know... It is also possible that people in this world have a strong ability to adapt to this environment."

After saying that, she found that Xiwei didn't seem to be listening to her, but stared at the outer wall of the world axis and was stunned, and couldn't help but feel curious.

"What are you looking at?"

She reached out and poked Siwei, causing the latter to almost fall off Gundam (yes. They came down on Siwei's Gundam).

"Surely, someone else has come here," Siwei complained casually, but was completely ignored by Siwei. He understood that the girl's personality was very cheerful. In a sense, he was a little close to the tomboy and could only smile helplessly. He said what he had just discovered: "There is an unknown energy remaining on the wall, which is not the magic that I know, and it is also different from the prayer you used before."

"The power system in my world is quite chaotic. Unlike you, almost all of them are magic, but they are simply different attributes." Xiwei lifted up the ends of her hair and looked at the place where Xiwei pointed. Her long black hair swayed with her movements: "In addition to the power of prayer, this world also has natural spiritual light, soul ripples, divine grace glow, etc., which are almost not of the same origin. For example, some people will extract the blood of monsters into their bodies and refine them into a special bloodline called "source blood". After these guys activate the source blood, they will have a power similar to monsters, which is called source blood power."

Because he does not have the keen sense of energy like Xiwei, even if he looks at what Xiwei points out, the girl doesn't see anything useful.

In the end, Xiwei could only record the energy fluctuations slightly and continued to dive with Xiwei.

"Speaking of this, when you chased the Ozaki core, didn't you dive quite far? I took the time to look down and wanted to find you. But I couldn't see anything except some flashes of light."

Sivi found a flat spot on Gundam, sat anywhere without any image, and then found a topic bored.

"That thing escaped very quickly, and it took me a lot of effort to chase it." Xiwei said with a wry smile: "After all, I left this thing at that time (she photographed Gundam). Although my own flying ability is impressive, my movements are not flexible, and it is very troublesome to chase it. Fortunately, the thing is very weak and the weakness is obvious, so I killed it with one sword. Later, in order to save you, I rushed up directly..."

There was an awkward silence between the two.

After a while, Xiwei scratched her face a little embarrassedly: "Anyway, thank you for saving me."

"This world is my territory at least. Letting you die as a guest on another territory is not a good thing for my reputation~"

The little girl raised her face proudly, and without waiting for Xiwei to continue saying something, she hummed an unknown song.

The melodious singing echoed in the dark corridor. Although it was an a cappella, the wonderful melody of the original song could still be heard, and the girl's clear and sweet voice was surprisingly good.

At the same time, Xiwei also discovered the difference between the two again. Before crossing, Xiwei was the type of singing that was super bad. She was a ktv with her friends. When she came out, except for him, everyone else had a psychological shadow level, and she was nicknamed Shadow Maker.

After enjoying with his eyes closed for a while, Xiwei suddenly opened her eyes and frowned: "Xiwei, please stop for a while."

"What's wrong?"

The girl stopped singing and looked at Xiwei curiously.

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

After a while, he opened his eyes again: "I originally thought that the strange energy I discovered just now was left by the uninvited guest when he sent Ozachi here. But now it seems that I'm afraid something is wrong."

"Didn't Ozachi get it from the master of that kind of energy?" Siwei touched his nose thoughtfully and asked.

"No, this is not certain yet." Xiwei shook his head, and then stopped keeping it in hiding: "But he got it, I think it would be better to ask him directly."

"You mean, did the master of that energy not leave this sinkhole, but hid below?"

"That's it." He nodded and affirmed the girl's guess.

So under the control of Siwei, the large alchemy humanoid (that is, Gundam) they were riding accelerated and flew downwards. The feeling of weightlessness like bungee jumping filled the whole colleague, and a figure appeared in the field of vision that the two of them blessed their night vision ability... (To be continued.)
