It didn't take long for Li Fei to come to the deepest part of the "A*Polo" basin, which was more than ten miles above the ground. Li Fei felt that the aura in the depths of the basin was significantly thicker than in other places, and he searched carefully, but found nothing worth noting.

Half an hour later, Li Fei disappeared at the bottom of the basin. Because Li Fei had a new idea, he guessed that the ancient teleportation array might not be on the surface of the moon at all, so he directly used the Earth Escape Technique to drill down.

After several successive earth escapes, Li Fei estimated that he had gone down for dozens of miles, and found that the earth escape technique was almost impossible to perform, because the geology below was almost entirely a mixture of metal and rock.

In desperation, Li Fei temporarily learned the Golden Escape Technique, and found that the Golden Escape Technique was more mana consuming, and the distance was shorter! Li Fei continued to retreat while practicing...... I don't know how long it has been, how many times I have used the escape technique, Li Fei is exhausted, and there is not much mana left.

He could only stop for a while, Li Fei used the last bit of mana to force out a small space around him, and solemnly took out a bracelet, which was the bracelet that stored spiritual power from the father and daughter.

In the past, when he was on Earth, the spiritual power bracelet was useless to Li Fei, because there was no spiritual power to store, and it was only used in the few years on the moon.

The first time he injected spiritual power into it, he startled Li Fei, because the bracelet was like a bottomless pit, and it sucked Li Fei's nine-layer mana almost instantly!

Li Fei hurriedly threw off the bracelet, and after a while, he carefully picked up the bracelet and tried to suck the spiritual power back, but there was no big accident, and he sucked it back in an instant, but it was discounted, and there were about three layers of mana that did not come back.

After many tests, Li Fei had a preliminary understanding of the spiritual power bracelet and mastered its basic characteristics. Later, Li Fei injected spiritual power into the bracelet when he had time, at least hundreds of times, but the bracelet was still not full, but the color changed, from the original very ordinary light green to light red.

In order to make progress as soon as possible, Li Fei absorbed spiritual power directly from the spiritual power bracelet, and the mana was replenished in an instant, and he continued to retreat downward.

In this way, Li Fei absorbed it from the bracelet as long as his mana ran out, and then continued to retreat. After Li Fei absorbed the spiritual power from the bracelet for the thirtieth time, he finally escaped from the metal-rock mixing area and appeared in a small spherical space.

The diameter of the spherical space is two or three zhang, the spherical wall does not know what material it is made of, it is very strong, and at the same time it also has the effect of isolating the divine thoughts, there is nothing else in the space except some dust, but there is a round hole with a diameter of about three feet leading to the nearby spherical space. Li Fei looked at them one by one, and finally understood what this was, it was a honeycomb! A super-large honeycomb!

Li Fei also found another feature, that is, the size of the honeycomb in the same layer is the same, and the further down it gradually increases, the thickness of the honeycomb in different layers is also different, and the lower it goes, the thicker it becomes.

After figuring out the general structure of the honeycomb, Li Fei was full of curiosity about the next trip, and believed in the possibility that the moon was "artificial".

Sweeping all the way down, Li Fei found that some honeycombs were sporadically damaged, and the aura had also changed, becoming thicker and thicker.

At least after half a day, Li Fei estimated that he had traveled at least seven or eight hundred miles. Along the way, Li Fei's heart was extremely shocked! The endless cellular space is not only too numerous to count, but also extremely regular, if it is said that it is naturally formed, he will not believe it if he kills Li Fei!

Thinking of the notebook in the Wangxian Palace, Li Fei already believed the statement in it - the moon was created, at least transformed!

Li Fei thought to himself: "The moon is also a celestial body, even if it is transformed, how much magic power does it need to do! If it is by manpower, it is definitely an incompleteable task!" Sighing, Li Fei shook his head, shook off this headache, and cautiously continued to explore......

After descending for another distance, there was no honeycomb ball under Li Fei's feet, but a flat ground, and Li Fei estimated that the honeycomb structure ended here.

Each of the last spaces was large, at least more than a few miles in diameter, like a huge semi-circular ball upside down, with circular holes leading to the adjacent large spaces on the front, back, left, right and top.

Because he hadn't found any danger, Li Fei chose an exit at random and swept over. A quarter of an hour later, Li Fei came to a more damaged hall.

Li Fei found that there were obvious traces of a fight in this hall, and his mind swept it carefully, and found that there was a corpse in a corner of the hall, but it was a long time ago, and only the skeleton remained.

Coming to the side of the skeleton, Li Fei took out a large flashlight and shone it on the skeleton, and found that the head of the skeleton had been cut off and rolled aside, and then carefully checked the surroundings, there was nothing, and he casually released a fireball to burn the remains, and was surprised to find that it couldn't be burned!

After Li Fei swept away the dust outside the remains, revealing a silver luster like metal! After some research, there was no valuable discovery, Li Fei ignored it and continued to explore.

An hour later, Li Fei found three bodies in a hall that was only slightly damaged, all three of them were lying on their stomachs, and their heads were rolling down more than ten zhang away.

After checking it carefully, Li Fei guessed that the three people should have been killed in seconds during the flight. After looking around with a flashlight, Li Fei found that there were three yellow flying swords under the cover of dust, two of which were more than two feet long, and the other was only a few feet long, all of which were dull.

Li Fei used his hand to play with them one by one, and happily put in the blue bracers. Then, Li was pleasantly surprised to find that the storage treasures of the three were still there, two bracelets, and a belt, all engraved with the same pattern, guessing that the three should belong to the same organization.

Li Fei unceremoniously picked up all three treasures, picked up one of the bracelets, swept it with his divine thoughts, and found that the space was not large, and it was only the size of a few feet, there were a lot of things, but they were relatively miscellaneous, and the entire space was almost filled, and what particularly caught Li Fei's attention was a small pile of glittering small gems of various colors.

Li Fei took out a few gems to play with, and the gems were only the size of his thumb, but they exuded abundant spiritual power! Li Fei estimated that this should be the so-called spirit stone! Because it was mentioned in that notebook.

The second bracelet was similar to the first, and there was nothing special about Li Fei's attention. The last belt, Li Fei's divine thoughts showed a look of great joy, because the space inside was much larger than the previous two, the size of five zhang, especially the large pile of spirit stones that were enough to have millions of pieces, which made Li Fei very happy!

In addition, there is a small pile of slightly larger spirit stones, estimated to be thousands, Li Fei took out a few pieces and felt it, and he was even happier, because the spiritual power emitted by these slightly larger spirit stones was not a grade compared to those ordinary spirit stones!

In addition, there are hundreds of jade boxes large and small that have attracted Li Fei's attention, among which there is a jade box that is relatively special and relatively large in size, it should not be made of ordinary jade, because the jade box itself exudes strong spiritual power!

Li Fei took out this big jade box, opened it, and immediately showed a surprised expression! Because there were a total of thirty egg-sized large spirit stones inside, and the spiritual power emitted was beyond Li Fei's imagination......

In order to facilitate management, Li Fei named three kinds of spirit stones: primary spirit stones, intermediate spirit stones, and high-grade spirit stones.

Li Fei tidied up a little, first put all the spirit stones into his blue bracers, and then put some jade boxes and jade slips that he thought were more useful into the blue bracers, and ignored other things for the time being, directly put the bracelets and belts into the blue bracers, and finally cleared out some useless things and waste products.

In the past five years, Li Fei has not thrown garbage on the surface of the moon, and this clean-up has really cleared out a pile of garbage like a small mountain, and burned it clean along with the three remains! Li Fei watched the three corpses and garbage turn into ashes together, and felt that the level of these three people was much worse than the person he met before, and he thought: "If the person in front of him can leave a storage treasure, it will be developed!"

In the subsequent trip, there were no big waves, and although Li Fei encountered a lot of remains, there was nothing.

After searching for a few more days, Li Fei couldn't remember where he had turned, and finally found a different hall.

In the center of the hall there is a boss with a three-zhang square circle, and a teleportation formation is carved on the boss, and there are three grooves around the formation.

When he first saw the teleportation array, Li Fei was very excited, and thought that he had finally found the target! But after some research, Li Fei thought that it was not very likely, because the formation was too small, especially since there were only three grooves.

After trying the size of the groove, Li Fei took out three intermediate spirit stones and put them into the groove, pinched the trick to activate the formation, a burst of white light flashed, and Li Fei's figure disappeared......

After a while, Li Fei felt a wave of dizziness and appeared in a bright world. After the dizziness disappeared, Li Fei stepped down from an identical platform and began to look at his surroundings.

To Li Fei's surprise, this is a super-large space, or the world is more suitable, and if it is compared with the entire moon, it is a smaller world. Li Fei estimated that this should be the real core of the moon's interior.

Li Fei glanced around and found that this was an extremely beautiful underground world! At first, Li Fei thought that he had arrived in another place similar to the earth, because the landscape looked like an earth that had shrunk many times! Not only did there be air, water, but also flowers, trees, and the occasional animal!

What made Li Fei happiest was that the aura was very sufficient! After feeling the magic in detail, Li Fei was so shocked that he couldn't express it in words......

After Li Fei felt it well, he began to look for a teleportation array that could lead to the cultivation world. After Edgeworth flew into the air, Li Fei suddenly saw a huge circular mountain peak in the distance reaching straight into the sky, and he quickly flew over.

It took more than half an hour for Li Fei to fly to the peak. Looking up, Li Fei felt that this mountain peak was the real Optimus Prime, so big that he couldn't see the edge at a glance, and at the same time it was so high that he couldn't see the end at a glance! In fact, Li Fei guessed correctly, this mountain peak was originally one of the three hundred and sixty Optimus Prime supporting the core of the moon!

After watching Optimus Prime for a while, Li Fei continued to fly forward, and suddenly found that there was a straight bluestone avenue in front of him, and when he flew closer, he found that it was an avenue dozens of zhang wide. After flying along the avenue for another quarter of an hour, Li Fei came to a huge square. The square is dozens of miles wide, and there is a jade round platform in the center of the square, the diameter of the round platform is more than several miles, and it is thirty or forty zhang high!

Li Feifei came to the round platform to check for a moment, and finally showed a look of ecstasy! Because he had finally found the Ancient Teleportation Array!

After studying it for a while, the ancient teleportation array was so huge and complex that Li Fei was dizzy and dizzy! Li Fei didn't want to look at the formation diagram anymore, because he noticed that there were a total of twenty-seven grooves at the edge of the teleportation array, judging by the size of the grooves, it should be a high-grade spirit stone.

Li Fei sighed for a while, sighing that fate was really a coincidence, he had only obtained thirty high-grade spirit stones not long ago! It seemed that there was a providence in the dark......

Coming to the center of the round platform, Li Fei took a closer look, and suddenly his face became extremely ugly......
