Lu Xiaotian had not originally planned to send a secondary Primordial Spirit into this secret realm. After all, this place posed enormous dangers even to Void Refinement Realm cultivators. Losing some divine sense was nothing to worry about. As a fourth-grade Pill King, Lu Xiaotian had made extensive preparations before entering the star region, and he had brought plenty of spirit pills to restore his magical power and divine sense. On top of that, his Primordial Spirit was exceptionally powerful. Even if one or two, or even several, of his secondary Primordial Spirits were damaged, he could always replenish them given time—and it would not even affect his ability to fight. After all, if he got into a battle with other Body Integration Realm cultivators, with his current level of cultivation, he would not need most of his secondary Primordial Spirits.
A loss of some divine sense could be made up through cultivation. But once he lost a complete secondary Primordial Spirit, no amount of spirit pills or precious medicines could restore it. The only way would be to cultivate the Soul-Splitting Secret Art again and split his Primordial Spirit. But splitting his Primordial Spirit had been perilous even back when he was in the Void Refinement Realm, and he had nearly lost everything in the attempt. Now his cultivation was far deeper and his Primordial Spirit more stable. Splitting it again was no longer realistic; the odds of failure far exceeded the chances of success. Lu Xiaotian had no intention of trying to split it, only to lose several secondary Primordial Spirits in the process.
Lu Xiaotian had many cultivation techniques to study at present. Without so many secondary Primordial Spirits, he would never have been able to keep this vast undertaking going.
