The visit of the corpse devouring insect swarm, Soul Su was not affected, at this time the corpse devouring mother worm in his body seemed to fall into a deep sleep, and did not toss him anymore, but Soul Su also consumed too much cultivation and vitality because of the failure to seize the house and the previous anti-Yuan Divine Technique, and the spirit was not very good at this time, so the two just chatted a few words, and sent Qingyang away.

After that, Qingyang put all his energy into cultivation, although Soul Su asked Qingyang to stay, in fact, it was still for Qingyang's sake, hoping that he could have a little more time to cultivate in this cold pool, under normal circumstances, Soul Su would not take up too much time in Qingyang.

For most of the time, Qingyang spent his time in cultivation with the Iron Arm Spirit Monkey and the Alcoholic Queen Bee, but every once in a while, he would leave Hantan and go to the soul Su to talk and chat, and fulfill his promise, this matter had no impact on Qingyang, with the situation of Hantan, it was impossible for him to stay in it to cultivate all the time, so he should go out for activities.

Qingyang occasionally sends the Iron Arm Spirit Monkey to accompany the Soul Su, for the Soul Su, he is just a person who has been in this cold cave for too long, and wants to find someone to talk to, to evacuate the loneliness in his heart, as for the person who talks to him is a human or a demon, there is not much difference, the Iron Arm Spirit Monkey is clumsy and not good at words, but he is a good listener, just suitable for accompanying the Soul Su.

In this process, Qingyang learned a lot of secret past stories about Ghost Valley from Soul Su's mouth, but Soul Su was trapped in this ruin six hundred years ago, so all he knew was some old things from a long time ago, and now things are wrong, and the news has long been outdated.

Of course, there is also some useful news, such as about the anti-Yuan Divine Formula, Soul Su did not regard Qingyang as an outsider, nor did he feel that this anti-Yuan Divine Recipe could not be passed on to him, if it was in the past, he might still be afraid of these rules and abide by the previous promises, but now it is a long time ago, he has also looked at many things, and feels that those old rules are useless, not to mention that Qingyang cannot be regarded as an outsider, strictly speaking, he is also a disciple of Ghost Valley.

As the secret of the Ghost Valley, the Reverse Yuan Divine Technique has always been cultivated only by the great cultivators of the late Yuan Infant Sect of the sect, on the one hand, because he is too important, on the other hand, it also shows that he is too difficult, and it took a lot of effort for Soul Su to completely teach it to Qingyang, but fortunately, when the former Soul Su used the Reverse Yuan Divine Technique to save Yu Mengmiao, Qingyang had observed it up close, and had an understanding of many of the details in advance, so it was much easier to master.

Of course, the most difficult thing about the reverse Yuan Shen Jue is how to use it, the requirements for the monks are extremely high, generally only if the cultivation reaches the late Yuan Infant stage, the powerful Yuan Shen can support the consumption of the Reverse Yuan Shen Jue, and now Qingyang is not able to operate no matter what, in his case, at least he must cultivate to reach the middle of the Yuan Infant, and practice diligently on the concentration taught by the one-horned ghost king.

Another piece of news is that the secret technique of the transfer of the true element and the underworld element that Soul Su once said, it is said that as long as this secret technique is mastered, the immortal spirit monk can cultivate in a place where the Yin and Underworld ghost qi is sufficient, and convert the absorbed Yin and Underworld ghost qi into the true element, and the ghost path monk can also cultivate in a place where the spiritual energy is sufficient, and the absorbed spiritual energy can be converted into the underworld, and at the same time, the true element and the underworld can be transferred to each other.

In this way, the immortal monk can use the ghost path magic weapon, take the dark pill, disguise himself as a ghost monk, and the ghost monk can also use the spirit weapon to refine the spirit pill, so as to become an immortal spirit monk, and fully explain the truth that the Tao is the same way, this secret technique can be described as the extreme against the sky.

The name of this secret technique is called Yin Yang Xuangong, according to Soul Su, it was obtained from a cave in this ruins, when their brothers and sisters found a lot of treasures in that cave, including this Yin Yang Xuangong. At the beginning, this exercise was going to be distributed to Soul Li, but he didn't look at it carefully, thinking that this was a book about double cultivation exercises, and he didn't want it very much, so he exchanged him with Soul Su for another treasure, and when he later found out the peculiarity of this exercise, Soul Li wanted to change it back, but Soul Su refused to agree, so that he hated that Soul Force.

The difficulty of this Yin Yang Xuangong is not very high, Qingyang has mastered the first layer after refining for a few days, this first layer is mainly used for cultivation, that is, you can absorb and refine different energies into the energy you need, Qingyang tried it in other places, the effect is very good, after the Yin and Yang Ghost Qi from the outside world is absorbed by him, after the transformation of this Yin and Yang Xuangong, it becomes the true yuan and is stored in the body.

However, there is a cold pool in this cave, and the aura in the cold pool is more abundant than the yin and ghost qi outside, so this exercise is not needed now, and when it reaches the depths of the ghost valley in the future, when the immortal qi does not stop, it can be used for cultivation, and the effect should be very good.

And there is a second and third layer of this Yin Yang Xuangong, which is about the use of pills, magic weapons, and talismans, and after mastering them, these things can be completely interconnected, and Yin Yang Xuangong has reached the deepest depths, and it can even directly reverse a true yuan into an underworld element, which is no different from a ghost monk.

Before, Qingyang also thought that there were too few immortal spirit cultivators in the depths of the Netherworld, and if he went by himself, he would be too conspicuous, and he would not do anything, with this exercise, he could completely disguise himself as a ghost monk, and his actions would not be restricted, and it seemed that this exercise would have to be practiced more in the future.

The third news is about how to get out of this fog, the solution is actually very simple, is to let the corpse eaters take themselves out, as the corpse eater swarm grows, they have almost become the overlord of the entire ruins, no monster dares to provoke them, and at the same time, the corpse eater swarm has also figured out the terrain of the entire ruins. As long as a few are caught, their senses are sealed with special techniques, and then these corpse eaters are driven by divine thoughts, they will crawl out of the cold cave, and they only need to follow them closely to get out of this fog.

This method seems simple, but it has also taken Soul Su countless time and energy to sum up, otherwise he would have gone out a long time ago, and he would not have been trapped here for hundreds of years.

Soul Su didn't seem to be afraid of Qingyang's debts, and it didn't take long for him to fulfill all the conditions he had promised Qingyang in advance, but Qingyang didn't turn his face and didn't admit it, and honestly stayed in this cold cave to cultivate, the reason why he did this was that he was unwilling to violate his own principles, and he had to do what he promised, not to mention that he had a good impression of this Soul Su. The second reason is that after Soul Su cast the Reverse Yuan Divine Technique, Yu Mengmiao's situation has been alleviated, and the search for the Long-eyebrow Ghost King is no longer as urgent as before, so there is no need to rush out.
