With Ye Fan's cultivation, she couldn't feel this powerful magnetic field, let alone grasp the changes in the magnetic field, but Xuannu said that she could clearly feel it, as if she was telling Ye Fan that she still had cultivation in her body.

But Ye Fan did not doubt what Xuannu said, Xuannu's time on the earth may be earlier than the birth of human beings, she had lived in an ocean above her head before, and regarded this place as the last harbor for refuge, and it was understandable that she knew some ancient secrets.

"Childe, what should I do?" Sang Yuan trusted Xuannu's words even more, after all, it was the god she believed in, the person who brought her life and cultivation, and it could even be said that Sang Yuan was the mother.

"Scourge around, and if you can't find it, we'll go back!"

Ye Fan was unwilling to leave like this, so he asked to prove whether this underground "eggshell" really couldn't be broken, and the clues he had now were only, but there was a staff given to him by the old priest, and the old priest also said the problem of the "key".

Ye Fan can understand that the underground race may exist for longer than the existence of human beings, they have multiplied from generation to generation, and the purpose is not to protect this artifact underground, but to guard the key to open the way to the artifact, and the staff is the key to finding the key, and finding the key will also mean being able to open the "eggshell".

It took them less than twenty minutes to get from the surface of the sea to the bottom of the earth, and now there was still nearly half an hour, that is, an hour, and the time was completely in time.

Sang Yuan continued to use it as a drill to open the mantle layer around the eggshell, while Ye Fan continued to feel what special existence was around him.

The situation inside the eggshell is completely undetectable, and judging from the feedback from the Xuannu, she doesn't know what is inside, but she knows that there is an energy source inside the eggshell, which is also the best proof of the existence of the artifact.

"Childe, it seems that there is a small space, someone has been here!"

Sang Yuan said in surprise, she seemed to have made a meritorious service, and she wanted to ask for merit in front of Ye Fan. Ye Fan used his spiritual sense to probe in the direction that Sang Yuan said, and sure enough, in the middle and lower part of the eggshell with a diameter of dozens of kilometers, there was a small space of about a few square meters, and if he didn't explore carefully, it would be impossible to know at all.

Several people arrived in the small space together, and it was also a passage from a distance, and they also stopped in front of the eggshell, the eggshell did not have any cracks, and there was no place like a keyhole, and there was no trace of the existence of the key in the small space.

Ye Fan looked at it and said, "The soil is a little new, but the predecessors have been here before?"

"Nope. Xuannu shook her head, "Maybe someone else came after that." ”

"That should be shadowless. The last time I saw her in the underground ocean, she must have been to the underground at that time, and explored the situation around this artifact, and she was even more sure that her predecessors did not hide the artifact privately. Ye Fan thought of the situation when he saw Xihe next to the big blue crystal before, Xihe looked very confused at that time, and he had never seen Xihe be so distracted.

Sang Yuan said: "Childe, it doesn't look like there are any secret rooms or secret passages around here, do you want to send a large number of cultivators here in the future and let them look around carefully?"

"There's no need to make a big deal out of it. Ye Fan said, and suddenly took out something from the storage bracelet, not only Sang Yuan and Xuannu were puzzled, but even Li Zhaojun, Min Yan and Lan Jing looked at him curiously, what he had in his hand was not the staff given to him by the old priest, but Xiao Hongjing.

Since Xiao Hongjing caused that phantom killing in the land ** under the Dead Sea in the Pangu Secret Realm, she has been in a dormant state, but Xiao Hongjing already has the demeanor of a spirit after all, and it is very likely that she is the next crystal that can turn into a girl. Now among the four small crystals in Ye Fan's body, only Amethyst has obtained a human body, and the small blue crystal was first received by Ye Fan, but it is still only a small crystal, not even in the form of a spirit, black crystal and red crystal have the form of a spirit but have not become a girl.

"What are you going to do?" said the Xuannu with a frown.

Ye Fan said: "Seniors may not know, this red crystal was obtained by me in the idol of the underground palace, and it has always been worshiped as a sacred object of the underground race, and the underground race regards me as their god, and even the person in the idol is a little similar to me, reaching out to the sword I am holding, which is also similar to the fire dragon sword I hold." In that case, then I'm just going to verify whether the idol in the underground palace really exists, and whether the prophecy will be true!"

Ye Fan said and sacrificed the fire dragon sword, and the fire dragon sword, as a crimson flame power, can also exert great power in the high temperature of the underground environment, and the little red crystal was directly inlaid on the hilt of the fire dragon sword by Ye Fan according to the position marked by the statue.

When Ye Fan raised the long sword according to the god shown in the idol, Xiao Hongjing also burst out with a strong red light, but seeing that the originally unbreakable eggshell also emitted a faint red light at this time, this change was also unexpected by the Xuannu.

"What's going on?" Xuannu was also shocked.

She didn't find any way to break the Pangu seal herself, but she was actually discovered by Ye Fan, and now it seems to be effective.

Ye Fan did not directly use the sword to chop the eggshell, but looked down at Xiao Hongjing, at this time Xiao Hongjing seemed to wake up, but it couldn't leave Ye Fan's hilt, she seemed to prefer to be Ye Fan's hilt, feeling controlled by Ye Fan's powerful force. And at this time, she is like a rune, with a special symbol on her body, and this symbol coincides with the symbol presented on the eggshell.

Ye Fan said: "No wonder the red crystal has always been sealed on the statue, it turns out that it is the key to opening this artifact!"

At this time, he finally took out the staff that the old priest gave him, and the staff was dim at this time, but when Xiao Hongjing transferred from the hilt of the sword to the head of the staff, everything was different, and the eggshell in front of him seemed to suddenly appear A transparent mist of water seemed to be able to lead directly to the inside, allowing Ye Fan to retrieve the artifact inside.

"Come in!" Ye Fan shouted, "We don't have much time, after we get the artifact, leave immediately!"

This time, Ye Fan had clearly felt that the surrounding magnetic field was gradually getting stronger.

Li Zhaojun and the others did not hesitate, and Ye Fan walked through the mist together and entered the eggshell, the eggshell was not substantial, but hollow, a huge hollow in a range of dozens of miles, emitting red light around it, which also made the space inside the eggshell very bright, even if it was more than ten kilometers away, several people could still clearly see that there was an "artifact" emitting a light red light in the center of the eggshell.

This artifact looks unpretentious, and when you look closer, it just looks like a three-foot-long short blade.

When Ye Fan's hand touched the short blade, the red light on it suddenly disappeared, turning into an object like an ordinary dagger.

Xuannu said coldly: "This is the Heaven Splitting Heaven, one of the three artifacts used by Pangu when Pangu opened the world. It is the first of the three great artifacts of the ancients!"
