Before long, Li Yunmu and Ye Qing's mortal soul completed their transaction. Both sides were quite satisfied and seemed to have forgotten their previous conflicts.
As soon as the trio came out of the heavenly world, Li Qinghong frowned and said, "Since he is acting this way, he might have a method to escape after his mortal soul is strengthened. If that happens, then not only can we forget about learning the secrets of the origin world from him, he will even prepare many formidable enemies for us."
Li Qinghong's underlying meaning was that they should immediately extinguish his mortal soul.
"I also understand this point, but we definitely cannot miss out on the cultivation method for a mortal soul. This would be our future capital. Moreover, a prey who has tasted honey will want to obtain even more. After this first time, sooner or later, he will be unable to resist spitting out the secret," Li Yunmu said with certainty.
"You mean Devil Soul Refining?"
"Yes, if I didn't have that cultivation method, why would I be so confident in making him fall for my trap? As long as he experiences the effects of Ghost King's Body Refining Method, the person who will be requesting to tell a secret next time would be him," Li Yunmu claimed with confidence.
As long as Ye Qing's mortal soul remained within the heavenly world, regardless of whatever tricks he tried, he wouldn't be able to escape from his prison. As long as Li Yunmu stuck to this bottomline, he would always have the initiative.
Soon, the three of them huddled together and began to investigate the method provided by Ye Qing's mortal soul, desiring to enjoy the benefits of congealing a mortal soul. In truth, this wasn't a real cultivation method, but knowledge and tricks to congeal a mortal soul.
These tricks to congeal the mortal soul were known as "Preserving Infant Soul".
It emphasized on how to exploit heavenly materials and earthly treasures together with nine strange materials to refine one's infant soul, which was a formidable carrier. If they could do that, then after they died, their mortal soul would be preserved.
This Preserving Infant Soul was simply a miraculous method. Li Yunmu didn't know which eccentric person had figured it out, but he knew that this method certainly didn't originate from his Earth.
"Clever, truly clever. This Han Xiaozi is truly a talented genius, given that he has created such a formidable method. This provides a whole new path for human cultivation."
Demon couldn't help but praise it.
It couldn't be denied that Han Xiaozi who had created this Preserving Infant Soul was indeed a monstrous genius.
According to him, as long as one refined their infant soul using this method, it would equivalent to having a second life in the form of a mortal soul.
Moreover, with this soul infant, one could gradually walk on the path of unconventional cultivation. The inheritance of Ghost Clan was precisely an example of such cultivation method.
Soon, Li Yunmu used Han Xioazi's memory fragments and associated them with Ghost King's Body Refining Method and Devil Soul Refining, the two secret techniques of Ghost Clan.
Suddenly, the trio gained an enlightenment. These two secret techniques seemed to have been created for the follow up cultivation of infant soul. Not only were these two secret techniques, even Ghostly Image Substitution and Ghostly Evasion were also compatible with life-forms like infant soul.
With both sides mutually compatible with each other, it was equivalent to double the reward for half the effort. The effects produced using this method would far surpass forcefully cultivating Ghost Clan's inheritance using corporeal body.
"Unimaginable, according to Han Xiaozi, as long as this infant soul cultivates the techniques of similar life-forms, it can even separate from the human body for a period of time. After the strength of the infant soul increases to the level of influencing matter, it can even forcefully occupy another person, thus obtaining another physical body. How can such a dreadful method exist in this world? It is simply unimaginable."
Li Qinghong couldn't help but turn cold while looking at this method.
The three of them finally understood the reason why Ye Qing's mortal soul was able to cultivate Ghost King's Body Refining Method, which was because it was compatible with the infant soul.
If the infant soul could be regarded as an alternative body, then Ghost King Body would allow it to obtain sufficient strength.
It could then use it to reach the level of affecting matter, and, according to Han Xiaozi, even seize another person's body, obtaining it for oneself.
This way, both the person's corporeal body and infant soul could achieve immortality. Whenever one's corporeal body aged, they could use the infant soul to seize a young body again and again. With this method, one's infant soul would have to continuously struggle against the defenses of another person's body, and after a long time, once it would mature properly, it could even break through to become a deity.
The trio had to accept that this sort of eccentric and unconventional cultivation method caused their hearts to pound fiercely. But Han Xiaozi also stated that they would require three heavenly treasures, of which only one was available in the origin world. As for the other two, they were either extremely difficult to find or perhaps didn't even exist.
According to the narration, the other two materials could only be found within the secondary planes. Until Li Yunmu looked through the description of the secondary plane, he was still all right, but once he read through it, he was astounded.
Based on the environment and power composition of the secondary plane as described by Han Xiaozi, it was completely identical to the Earth from which Li Yunmu and the others had arrived!
Bang!
The three of them seemed to have been struck by a thunderbolt. This information was too explosive!
Li Yunmu and his two followers kept looking at each other, their hearts filled with extreme shock.
It seemed that this Han Xiaozi had visited Earth. No, he definitely had done so. Otherwise, he wouldn't have been able to obtain these two materials and refine his mortal soul.
"Wait a minute, this Ghost Fate Stemen, I seem to have heard of it!" Demon suddenly exclaimed. He lowered his head and began to think. Soon, an expression of extreme shock appeared on his face, and he loudly said, "I remember now, this Ghost Fate Stemen was one of the materials I used when I was trying to merge with the ghost bloodline.
"As for this Underworld Devil River's water, I used it as well. Both of them are relatively common materials within the Sixth Dimension. My god, why is this Han Xiaozi thinking that they are heavenly treasures."
Demon was bewildered.
After being reminded by Demon, Li Yunmu immediately entered the system and asked it about the information regarding Ghost Fate Stemen and Underworld Devil River's water.
Soon, he found the information about these so called 'heavenly treasures' within the records gathered by the system.
Ghost Fate Stemen – a plant which possesses consciousness and grows within the Sixth Dimension. Relatively common.
Underworld Devil River – a river flowing near the territory of the now extinct Ghost Clan. Any amount of water can be obtained from it.
