After reading it, Han Fei was also silent for a while, cultivation is actually cruel, on the earth, everyone knows that life is limited, so no one pursues longevity but pursues timely pleasure.

It's different here, people here can cultivate the Tao, and the Tao can pursue immortality, it is this glimmer of light that makes the cultivator walk for the Tao all his life, but how can this heaven and earth avenue be easily cultivated, the vast majority of them can only be exhausted of qualifications, waiting for old age to die.

Turn another page, it is already the introduction of the sword array, this set of sword arrays is based on eight swords, forming a small gossip sword array, and then the eight small gossip sword arrays can form a big gossip sword array, and even eight big gossip sword arrays can be used to form a larger gossip sword array, and so on, each upper layer, the power will naturally be many times stronger, and these swords can be magic swords, or they can be swords condensed with Taoism!

Han Fei's eyes lit up, originally he thought that this must be a magic weapon to cooperate, just like Kong Qianqiu's sword array is three spirit swords, and the entrance to this set of sword formations actually requires eight, if you want to call Han Fei to make up, I don't know how long and what month it will take to make up the kind depicted in the book.

Now this book actually says that it can be condensed into a sword with Dao Technique, if Han Fei had no way before, but now the Dao Technique he learned in that discipline just happened to be Dao Technique Condensing Sword, thinking about it this way, the original owner of the cave mansion was deliberately set up, first comprehend the sword gathering, and then get the sword array to cooperate, this can be regarded as a complete set of ground-level advanced Dao techniques!

Although Han Fei couldn't use many Dao Swords now, and his comprehension of the Dao of Water was also very weak, with Han Fei's qualifications, sooner or later he would be able to perfectly mobilize thousands of Dao Swords to form a large array, and that kind of power was estimated to be stronger than ordinary Heavenly Rank Dao Techniques!

After looking at it briefly, Han Fei still chose to put it away first, he had never been exposed to this kind of formation-type Dao technique, and it was unlikely that he would learn it as casually as before, so he had to study it slowly in the future.

Looking at the shelf again, there were several empty seats behind the shelf, as if something had been put on hold before, and then it was taken away for some unknown reason.

After checking to make sure that nothing was missing, Han Fei walked out, and after going out, he happened to meet Su Mengli who came out of another stone room.

"Han Fei, have you gained anything? My side is basically a few rotten items, only a few strange things for refining, which are considered treasured materials, which are not bad. Su Mengli saw Han Fei come out, smiled and said what she had gained.

"I have gained something from this stone room, a top-grade spiritual weapon, a material that I don't know the grade, and a sword formation book" Han Fei didn't hide it, anyway, since the two of them came together, they just had to take what they needed when the time came, and the two of them didn't have to fight for the things in the cave.

"It's not bad, but now that the stone chamber has been searched, do we need to go back next?" Su Mengli was also more happy, she and Han Fei came here purely to avoid the people who were chasing her, but she didn't expect to get something good.

"Is the search finished? If it's just these things, then it's more strange, since the owner of the cave has left things in the cave, and there are even some traces of daily life, if it's just to pass on this set of Taoist techniques, then why did he set it up so complicated, and the aura here is clearly not natural, and we didn't find any traces of the spirit gathering formation in the cave. "Han Fei has always had this doubt, this cave mansion is set up too strangely, so secretive, but after coming in, it is so ordinary.

Although these things left behind are not bad, but if they are really put on a peerless master in the distraction period, these things are too unsightly, only this set of sword formations is not bad, and this set of sword formations can be obtained so easily after the previous test, on the surface, this cave mansion is to spread this set of sword formations, but Han Fei just feels that it is too strange.

Su Mengli also thought about it, she had also experienced everywhere, and had broken through some ancient predecessors' caves and the like, either to leave a legacy or to sit in the tombs, and here it always felt like the two.

"Perhaps, this sword formation is just a cover, there may be other mysteries here!" Han Fei wasn't very sure, he just had an intuition.

"Then let's search carefully together, pay special attention to find the source of the aura here, I estimate that there was no aura here, it should have been leaked after the protective formation was damaged, this place is very old, it is normal for the formation to be damaged, isn't that the door broken?" Su Mengli also guessed according to Han Fei's thoughts.

"Okay!" Han Fei actually thought the same thing. Since there is a soul-gathering formation hidden here, the place of that formation may be the real secret of the cave, and if the formation is damaged, they may be able to enter there according to the broken place.

Just do it, the two of them started to check again, the aura in the cave is very strong, and the cave door is leaking again, so the direction of flow they feel is mainly towards the cave door, but since the aura has been leaking but has not weakened, then as long as they find a place to replenish the aura here, it is the place where the formation is damaged.

The two of them continued to feel the changes in the aura in every corner of the cave, although this cave was not big, but neither of them had divine consciousness in the Jindan period, so they could only feel it with their perception at close range, and it took a full day for the two to check all the stone chambers, but they still found nothing.

"Strange, could it be that I guessed wrong? The aura here is actually produced by the cultivation of that master at the beginning, and because the aura is too sufficient, although it is draining, the speed of loss is not fast, and the concentration inside has not changed significantly. Han Fei muttered to himself, he could only make other guesses about not finding the place where the aura overflowed.

"Probably not, although the aura here is rich, it has not changed so much that it has not changed, I guess we may have missed something. Su Mengli shook her head and said, in her opinion, the aura is useless to her, and it is too strong and affects her, so she is extremely sensitive to the concentration of aura.

"But we've gone through the hall and all the stone rooms here, and where else haven't we checked?" Han Fei said depressedly.

"There is another place, you forgot, that corridor has not been checked when we came" Su Mengli actually just remembered, patronizing the inspection of the cave mansion, but forgetting that the corridor is also part of the cave mansion, and it is also within the scope of the protective formation.
