According to the artifact-refining manual, the Five Poison Soul Severing Sword was not a single sword, but five poison swords of different attributes that could be forged. They could injure the Divine Souls of Foundation Establishment Realm cultivators, and their power was terrifying.
Clearly, the Qi Family had planned far ahead and prepared for a long time.
If things truly went as they had envisioned, the five Ghost Infants could create five Foundation Establishment Realm combatants.
Even if they were only pseudo-Foundation Establishment, with five different Soul Severing Poison Swords, they could form a sword array fully capable of challenging a late-stage Foundation Establishment Realm expert.
But Zheng Yi had a wildly imaginative idea. According to his plan, if he could merge the five Five Poison Soul Severing Swords into one, use Blood Fetus Ghost Infants as their Artifact Spirits, and refine them into a Lifebound Sword Embryo, he could achieve Foundation Establishment through a Five Elements Magic Tool.
Once the Five Poison Soul Severing Sword came into being, even Zheng Yi could not estimate just how powerful it would become.
Zheng Yi set aside the matter of the Five Poison Soul Severing Sword for the time being. After all, the materials needed to forge Magic Swords capable of threatening Foundation Establishment Realm cultivators would naturally be exceedingly precious, not something he could plan for now.
Moreover, his realm was still low. He was only at Qi Refining Stage Four, so there would be plenty of time to make plans after his strength improved.
Zheng Yi continued cultivating the Profound Fiend Body Tempering Art. In the Da Yi Immortal Domain, rapid progress in this technique required the support of vast quantities of cultivation resources, something ordinary cultivators simply could not afford.
Yet Zheng Yi had creatively replaced those cultivation resources
