Since he already suspected that there was a protective formation arranged in the cave, Ye Qiuli naturally would not act recklessly, in line with the principle of caution and no big mistake, after taking out the Yunlong water and other protective magic weapons from the Qiankun bag and putting them on, he used another extremely common trick of "throwing stones to ask for directions", dug a few rocks from the passage and threw them down to test it, ready to see the specific reaction.

The distance of 1000 meters is not shallow, but it is not deep, even if the gravity of the moon is much smaller than that of the earth, the stones that fell from the sky quickly fell to the bottom of the cave, and the result that Ye Qiuli wanted was also fed back very clearly.

Probably because the age is really old, the formation has failed, or the person who opened up this underground cave has not arranged any formation at all, which makes people worry in vain, anyway, Ye Qiuli threw down several rocks in a row, and there was no accident, even if he smashed the broken stone block into the small purple palace at the bottom of the cave, he was not hindered by anything, and smashed it very accurately.

After making sure that there was no danger, Ye Qiuli took out a long rope from the Qiankun bag with peace of mind, fixed one end in the passage, and the other end hung down towards the ground of the cave. When all the preparations were made, he crawled out of his hiding place, grabbed the long rope, carried the light work, and descended lightly to the ground at the bottom of the cave, and then walked to the most striking palace.

When he got to the palace, Ye Qiuli found that this mysterious building was also made of rock, and the means of construction were very superb, the entire palace was completely connected, and there was no connection between the parts, giving people the feeling that it was almost cut out of a whole piece of rock. Although the stone palace is not big, it is exquisitely carved and painted, and it is no worse than the classic ancient buildings he has seen.

However, there is one slight difference between this rock palace and the classical palaces that exist in reality, that is, it is not marked with any name. At this time, the two rock gates of the palace were tightly closed, and the position of the door was also blank, and there was no name such as a certain palace or a certain hall that would normally be engraved.

After spending more than ten minutes before and after, carefully observing the palace, Ye Qiuli turned back to the gate again, ready to push the door in and take a look at the situation inside. He believed that there must be relevant information inside the palace that could tell him the ins and outs of the palace and this underground cavern.

As for the closed rock gate, Ye Qiuli had already made preparations, if the gate couldn't be opened, he wouldn't think of any other way, he would directly use the Rainbow Sword to cut it open, and choose the simplest, most direct and most violent way to solve the problem.

Because in the inspection just now, he had determined that this palace was not a magic weapon, it was a rock building, and it was not a great treasure, that is, the material was relatively special and rare, the stone was very solid and dense, and it was still undamaged after a long time, even if the gate was cut by a flying sword, there was no special loss.

It's just that the reality proved that Ye Qiuli's preparation was completely superfluous, and the two doors of the Rock Palace were not buttoned with locks or anything like that, and he only used a little force to push them open. As soon as the door was pushed open, the furnishings in the palace were displayed in front of him at a glance.

The situation inside the palace was not much different from Ye Qiuli's guess, and there were no cultivation methods such as space expansion, it was still a normal size, with a length and width of about five or six meters around it, and a height of seven or eight meters, which looked no different from an ordinary palace.

The interior of the entire palace is also the same as the cave outside, empty without any superfluous items, not even a pillar or beam, it is indeed very much like it was hollowed out of a whole rock. The floor is paved with two other unknown black and white cornerstones, which are painted as Tai Chi, with fluorescent light on them, and the entire interior of the palace can be seen clearly. In addition to this main hall, there are two side halls next to it, each connected by a stone door.

After looking at the entire palace with a leisurely view, Ye Qiuli quickly focused his attention on a rock long table placed in the center of the back wall of the main hall, where there happened to be a few items that looked like the cultivators had left behind, but they were very similar to the scene he saw when he first entered the Fuyun Immortal Mansion.

"Hehe, it seems that the way of doing things of these cultivators is similar, they are all simple and clear. ...... I don't know what's left inside, but I hope it doesn't disappoint me. Seeing this scene, after being 100% sure that this cave was built by a cultivator, Ye Qiuli didn't think about it, muttered a few words in a low voice, stepped forward to take those special items, and began to check them carefully.

There are actually not many items on the stone table, there are only three pieces in total, and all of them are jade slips, arranged on the table in order from small to large, and the colors are not the same, the small one is cyan, and the two large ones are purple. Obviously, their quality is not the same as the amount of information they can carry.

Taking the jade slip in his hand, Ye Qiuli just looked at it a little and then chose the cyan one and started reading. This jade slip seems to be of slightly inferior quality to the other two, and what is recorded in it is obviously a little secondary, probably a miscellaneous record of the ins and outs of this underground cave.

Sure enough, the final result was not at all beyond Ye Qiuli's expectations, and what was recorded in this jade slip was the origin and details of these items in front of him. According to the description of the information in the jade slip, this palace is indeed a place where an earth cultivator named Xuanjizi built and left a place to hide scriptures, as for the cave outside, it is a natural existence, and Xuanjizi only polished and carved it after finding it, so as to form its current appearance.

Judging from the information recorded in the jade slip, this Xuanji Zi came from a unique sect called the Xuanji Sect on the earth, and happened to live in an era when the earth's cultivation world had begun to decline, but it had not yet completely decayed.

At that time, because of the frequent monk wars on the earth, the underground spiritual veins were basically completely shattered, and the spiritual energy of heaven and earth had slowly begun to disperse and drain, even those famous mountains and rivers guarded by large arrays, the spiritual energy in them was becoming thinner and thinner, and the cultivation resources such as spar medicinal materials were almost completely exhausted. In this case, the cultivation of Earth cultivators naturally became more and more difficult as a result.

Originally, when the teleportation array connected to the earth and other planets was still intact, they could also obtain resources from the outside world through the teleportation array, maintaining an increasingly severe cultivation. However, when the last remaining forces on the earth fought for control of the teleportation array, and accidentally destroyed the teleportation array, this last lifeline to maintain the existence of the earth's cultivation realm was completely cut off.

This Xuanjizi lived in such an era, and witnessed the destruction of the Earth Teleportation Array and the decline of the Earth Cultivation Realm. Therefore, when he finally cultivated to the realm of returning to the void after thousands of years of arduous cultivation and had the ability to fly out of the earth, in order to cultivate to become an immortal, he immediately embarked on the path that many of his predecessors had walked without hesitation - flying away from the earth and looking for other cultivation environments with excellent conditions.

Like Ye Qiuli, after Xuanjizi flew out of the earth, the first stop she arrived at was also the moon, and she accidentally discovered this underground cave when she was checking the lunar environment. It just so happened that at that time, when he looked at the earth for the last time, his mind suddenly drifted, thinking that once he left, there was almost no possibility of coming back again, and all his learning came from the earth, and it was a pity that he would be extinct from the earth cultivation realm.

Therefore, after discovering this very secret underground cave, Xuan Jizi suddenly had the idea of leaving behind his cultivation exercises, which did not necessarily need to be obtained by others, but he had to leave a little trace of his own existence. For this reason, he also specially used the escape method to escape to the depths of the moon, found a relatively strange rock, and used it to build the palace in front of Ye Qiuli, leaving the two exercises he cultivated in it.

Because this idea suddenly came to me on a whim, and he was not prepared to pass on his exercises in the earth's cultivation world, so Xuanjizi finally arranged it very casually, just found such a place on the moon at random, carved a few pieces of jade slips, and didn't do much arrangement, purely with the mentality of everything casual, which can be regarded as leaving a thought for simple descendants......

After reading this message, after having a clear understanding of the ins and outs of the underground cave, rock palace, and exercise jade slips in front of him, Ye Qiuli couldn't help but be glad, fortunately, at the beginning of Xuan Jizi's whim, he left the cultivation exercises on the inaccessible moon, if he returned to the earth again at that time and found a secret place to leave these exercises jade slips, it might have nothing to do with him at all.

After reading the records of the history of the development of martial arts collected in the Zangjing Pavilion of Shaolin Temple, Ye Qiuli knew very clearly how crazy those cultivators were in the era when martial arts were created. In order to collect the exercise materials left by the predecessors, that group of people searched almost all the famous mountains and rivers in the world, and any place where the relics of the predecessors of the cultivators could appear were searched by them, and the exercises and treasures left by those predecessors were also searched by them, and finally disappeared in the long passage of time.

In such a frenzied search, it is conceivable how much damage the caves and treasure lands left by those predecessors in the Earth Cultivation Realm have suffered. Among those treasures related to cultivators, there are no tragic murders, and those that can still be safely preserved are naturally rare, and there is no one in ten thousand. If these jade slips of Xuanjizi had been left on the earth, I am afraid that they would have been excavated long ago, and in the end, it would not be Ye Qiuli's turn to discover the secrets and obtain the benefits from them!
