Chapter 1140 - 517: The Book of Technique of Desire and Emptiness, Sangmu Dharma King of Haemother Cave
If the genuine "The Book of Technique of Desire and Emptiness" could be used to comprehend the ultimate Way, then this skill would undoubtedly be a divine technique.
Though the Nine-tailed Fox had received the Bloodline Inheritance of the Ancestor of Qingqiu Fox, like the Little Dragon, she was also limited by the great threshold of her own soul and authority. Even if the bloodline fully merged and the Shell reached the Immortal or Eternal level, it would still fail to exert the true strength of the Shell due to the weakness of the soul.
And if "The Book of Technique of Desire and Emptiness" really had such effects, it could greatly resolve the issue of the Nine-tailed Fox’s weak soul.
As for the side effects of this cultivation technique, they were completely non-issues for him who possessed the Flesh Authority.
Of course, Lin Xun’s thoughts were entirely driven by the purpose of mutual strength enhancement...
"I wonder if Valkyrie could cultivate this technique..."
Valkyrie had transformed her Shell into Immortal level in the previous Chapter, but her soul was only beginning to gestate and was far from grasping the authority, hence she faced the plight of falling to the Mythical+ Level.
If Valkyrie could also cultivate this technique, it would solve two major challenges for Lin Xun in one fell swoop.
However, it seemed rather unrealistic. Although Valkyrie appeared no different from a human on the outside and even had very realistic bionic modules, her internal structure was completely different from that of fleshly beings, so it was unlikely she could cultivate Buddhist techniques.
