Li Mu's eyes widened in disbelief. This was the second Tier Seven Spiritual Object he had seen, following the Star Beast Relic Pearl. Unlike the Star Beast Relic Pearl, which held the Space-Time Dao Principle, this Sinking Star Crystal Core bore the Gravity Dao Principle. It was indestructible and had attributes such as repelling spiritual isolation and blocking Divine Thoughts, making it a top-grade material for artifact refining.
Even with countless Spirit Stones, you couldn't buy such a material! Its attributes are particularly suited for refining a defensive Spirit Treasure. But no, with its properties, refining it into a Spirit Sword would also be excellent.
Li Mu's eyes gleamed as he conceived numerous artifact refining plans in his mind.
"Master Li, are you interested in this boulder? Do you recognize what material it is?" Lin Baoqing asked with concern as he looked at Li Mu.
